Denial, CRNP, MSN Committee Member Saint Vincent Health System Date Date c. > Abstract Hormone Replacement Therapy: A Patient Education Web Page Hormone replacement therapy (HRT) is used by perimenopausal women to manage the symptoms associated with menopause and for potential long-term health benefits. These potential benefits include protection against osteoporosis, heart disease, colon cancer, and possibly Alzheimer’s disease (Shaywitz et al., 1999). The decision to start therapy must take into consideration the potential risks of breast and endometrial cancer, and thromboembolic disorders (Cutson & Meuleman, 2000). The purpose of this project is to provide information to perimenopausal and postmenopausal women related to hormone replacement therapy. This information will be made available via internet and world wide web at www.velocity.net/~rrmartin.The web page was evaluated using the Model for Evaluating Printed Educational Materials by Bernier and Yasko (1991). The content is based on a review of the literature and is presented at the eighth grade level using the McLaughlin Smog Formula (McLaughlin, 1969). The topics covered include health risks, benefits, and alternative therapies. The theoretical framework for this project is the Neuman Systems Model by Betty Neuman (1995). Based on this theory, the nurse practitioner analyzes how sociocultural, developmental, and psychological variables influence a patient’s health practices (Reed, 1993). i Table of Contents Contents Page Chapter 1: Introduction... 1 Background of the Problem 1 History.. 1 Physiology 2 Treatment Issues. 2 Discontinuation of Therapy 2 Statement of the Problem 2 Therorectical Framework 3 Statement of the Purpose 4 Assumptions 4 Limitations 4 Definition of Terms 5 Summary 5 7 Chapter 2: Review of the Literature 7 Physiology Perimenopausal Years 7 Postmenopausal Years 8 8 Treatment Issues.... 9 Osteoporosis 10 Heart Disease... 12 Colon Cancer.. ii Alzheimer's Disease 13 Breast Cancer.. 15 Summary.. 17 Chapter 3: Methodology 18 Development of a Web Page 18 Factors Influencing the Adult Learner 18 Model for Evaluating Printed Education Materials 19 Predesign 19 Design 20 Pilot Test 20 I mp le mentation/D istribut ion 21 Evaluation 21 Summary 21 References 22 Appendix A: Web Page Overview 27 iii Chapter 1 Introduction This chapter provides a brief introduction to hormone replacement therapy (HRT), also known as estrogen replacement therapy or hormone therapy. Information includes the health risks and benefits of HRT, alternative therapies, and approximate cost of treatment. The theoretical framework utilized for this project is the Neuman Systems Model by Betty Neuman (Neuman, 1995). Assumptions, limitations, and definitions of terms are also included. Background of the Problem Issues surrounding perimenopausal and postmenopausal use of HRT include menopausal symptoms and physiology, pharmacological treatment, alternative therapies, risks and benefits, and reasons for starting or discontinuing therapy. Information needs to be available to women considering HRT so that they can make informed decisions. Changes associated with the perimenopausal and postmenopausal years were described in the medical literature as early as 200 years ago. History. The effects of menopause were documented during the 18th century when peasant women were thought to be unaffected by menopause while women of the upper class suffered from the loss of estrogenic function as seen by changes within their bodies and loss of social status (Lewis & Bernstein, 1996). At that time, the goal of treatment was to promote the excretion of toxins that were believed to be retained when menstruation became irregular or stopped. This treatment included the use of leeches and phlebotomy and was thought to restore sexual attractiveness (Lewis & Bernstein). 2 g to Lewis and Bernstein (1996), the first study conducted on menopause was published in 1933 and determined that the most frequent symptom (62.3%) was flushing. Based on these findings, the first therapy was aimed at symptom relief. Physiology. The perimenopausal years may be characterized by irregular menstrual cycles and erratic estrogen production generally affecting women between 45 and 55 years of age (Winter & Bernard, 1998). Signs and symptoms include hot flashes (vasomotor response); nighttime flushes, sweats, and sleep disturbances; genitourinary complaints such as vaginal dryness; and a decrease in skin thinness, muscle strength, and memory (Lewis & Bernstein, 1996). HRT may be used short term for symptom control (Yanni & Klein, 2000). The postmenopausal period begins when menses have ceased for 12 months (Papaioannou & Parksinson, 1998). Treatment Issues. At the center of HRT controversy is the debate concerning perceived risks versus benefits. The possible benefits of HRT include protection against osteoporosis, heart disease, colon cancer, and possibly Alzheimer’s disease (Gambrell, 1998). The risks associated with HRT are increased risk of breast and endometrial cancer, and thromboembolic disorders (Cutson & Meuleman, 2000). Discontinuation of Therapy. Women may decline or discontinue HRT for several reasons: breast tenderness, breakthrough bleeding, and fear of cancer or thromboembolic disorders (Cutson & Meuleman, 2000). Of these reasons, the fear of cancer and breakthrough bleeding are the most common (“HRT 2000: Pause for thought,” 2000). Statement of the Problem The decision made by perimenopausal and postmenopausal women regarding hormone replacement therapy will, in all probability, depend upon their perceptions of 3 potential health risks versus health benefits. For this reason, Mrmration related to side effects, health hazards and benefits, and alternative therapies needs to be made available from a reliable source. Theoretical Framework The decision whether to start ho:•rmone replacement therapy should be made on the basis of promoting health and maintaining wellness. One of the roles of the nurse practitioner is to educate the patient during this decision process by providing materials that will allow her to make an informed decision. The Neuman Systems Model (Neuman, 1995) demonstrates how sociocultural, developmental, and psychological factors influence a patient’s health maintenance decision. Sociocultural variables measure the relationship the patient has with family, friends, significant others, and community members (Reed, 1993). For example, a patient’s economic level may influence her health practices, beliefs, and lifestyle. In a primary care environment, these factors must be taken into account when developing a plan of treatment. Additionally, teaching plans must consider language, culture, and the methods of learning that are appropriate for the patient. The developmental variable in Neuman’s model measures cognitive abilities, education, and life experiences (Reed, 1993). The patient’s developmental age must be taken into consideration as well as her ability to conceptualize and respond to changes in health status. The psychological variable encompasses the mental and emotional aspects of the patient. Since the Neuman Systems Model is multidimensional and recognizes the variability and interactions that patients share with each other and the environment, it is an attractive model for the nurse practitioner. The emphasis on wellness and levels of 4 prevention speak to the heart of primary care. Since its R been usgd a guide for nursmg education and practice (Fawcett et al, 1982). By addressing the sociocultural, developmental, and psychological factors that influence a patient’s health maintenance decision, the nurse practitioner can effectively provide information relating to hormone replacement therapy and allow the patient to make an informed decision. Statement of the Purpose The purpose of this project is to provide information relating to hormone replacement therapy to perimenopausal and postmenopausal women. This information will be made available over the internet via the world wide web. Assumptions This project is motivated by the following assumptions: 1. There is a need for unbiased patient education material relating to HRT. 2. A significant number of perimenopausal and postmenopausal women have a desire to learn about short and long-term HRT therapy. 3. A large number of patients have access to the world wide web and are capable of reading and understanding the English language at the eighth grade level. Limitations The limitations of this project are identified as follows: T The internet-user audience is not entirely representative of the target population. Currently, the majority of internet users are Caucasians who are not in the perimenopausal or postmenopausal age groups and have a household income of greater than $75,000 anually (“Internet access in America,” 2000). 2. Those individuals who utilize the internet to research health related topics independantly are more likely to have a population. higher educational attainment than the general 5 Definition of Terms ormone replacement therapy (HRT) is a combination of estrogen plus progestin that partially replaces the body’s depleting hormonal stores as a woman goes through the perimenopausal and postmenopausal period (“Decision tree can guide recommendations,” 2000). 2. Estrogen replacement therapy involves the use of a natural or synthetic form of estrogen to replace, in part, the estrogen no longer produced by the ovaries (Ammer, 1995). 3. Perimenopause, the transition into menopause, includes a few years before and one year after the permanent cessation of menses and is associated with a reduction in estradiol and progesterone. Symptoms associated with the decrease in estrogen are hot flashes, night sweats, fatigue, irritability, forgetfulness, and headache (Li & Holm, 2000). 4. Postmenopause is a period that begins when menses have been absent for 12 months (Papaioannou & Parksinson, 1998). 5. Estrogen is a hormone produced by the ovaries and is responsible for female sexual characteristics and the cyclic changes within the vagina and uterus. Natural estrogens include estradiol, estrone, and estriol (Thomas, 1989). 6. Progestin is a synthetic form of progesterone, a hormone that is responsible for the cyclic changes in the uterus (Thomas, 1989). Summary Hormone replacement therapy can be benficial to the perimenopausal and postmenopausal patient. The advantages include a reduction in bone loss and prevention of osteoporosis (Cutson & Meuleman, 2000), heart disease, colon cancer, and possible 6 decrease in the prevalence, incidence, and severity of the dementia of the Alzheimer’s type (Gambrell, 1998). In addition, HRT offers relief from the symptoms associated with perimenopause such as hot flushes, night sweats, sleep disturbances, vaginal dryness, and changes to the skin, muscles, and memory (Lewis & Bernstein, 1996). When deciding to use HRT, the side effects and potential health risks must also be considered. Breast tenderness, breakthrough bleeding, thromboembolic disorders, and the fear of cancer are the most common reasons for decisions against using HRT (Cutson & Meuleman, 2000). This scholarly project will provide information for women who are attempting to make an informed decision regarding the advantages and disadvantages of HRT. It allows nurse practitioners to provide patient education material related to HRT. It utilizes the Neuman System Model which stresses the sociocultural, developmental, and psychological variables that influence a patient’s decisions relating to health care. The project is justified by the assum]iptions that a desire and a need exist for unbiased information, and that many affected women possess the ability to understand this material and the capability to access it over the internet. The audience is narrowed to these indiviuals. 7 Chapter 2 Review of the Literature Hormone replacement therapy is used by both perimenopausal and postmenopausal women. The topics surrounding HRT including relief of menopausal symptoms, physiology, risks and benefits, pharmacological treatment, alternative therapies, and reasons for discontinuation of therapy are discussed. Physiology The physiology of menopause is presented in terms of perimenopause and postmenopause. Treatment options and goals are dependent upon whether the woman is perimenopausal or postmenopausal. Perimenopausal Years. The perimenopausal years are associated with a reduction in estradiol and progesterone (Li & Holm, 2000). This period of time is also called the climacteric (Lewis & Bernstein, 1996). Menopause is a period between reproductive and postreproductive years (Ammer, 1995) generally covering ages 40 to 60 (Lewis, & Bernstein). Perimenopause may include women between 45 to 55 years of age (Winter & Bernard, 1998). It may precede menopause by 1 to 2 years and is confirmed by a follicle- stimulating hormone (FSH) level greater than 20mIU/ml (Lewis & Bernstein). Signs and symptoms during this period may include hot flashes (vasomotor response), night sweats, sleep disturbances, genitourinary complaints such as vaginal dryness, changes to the skin, decreased muscle strength, and memory problems (Lewis & Bernstein). Since these complaints are related to estrogen withdrawal from target organs, they impact long-term health status. HRT may be used during the perimenopausal period for symptom control (“Hormone replacement therapy,” 2000). Estrogen has been shown to improve mood and dysphoria by affecting serotonin in the central nervous system and also to decrease mood swings, depression, and difficulty with concentration (Cutson & Meuleman, 2000). HRT 8 also decreases hot flushes, urethral irritation, vaginal thinning, and dyspareunia. An alternative therapy for these symptoms include natural progesterone present in yam root, known as disogenin, which is prepared into a topical cream and may be topically applied for absorption or may be taken orally as Prometrium (Cutson & Meuleman). Alternatives may also include natural phytoestrogens called isoflavones which are soy proteins that may reduce hot flushes, bone loss, and total cholesterol and LDL cholesterol levels; vitamin E which is believed to stabilize estrogen levels; black cohosh which may suppress luteinizing hormones; chasteberry that may decreases prolactin; supplemental calcium and vitamin D, and many others (Cutson & Meuleman). Postmenopausal Years. The postmenopausal years begin when menses have been absent for 12 months (Papaioannou & Parksinson, 1998). The use of HRT after menopause is for long-term health benefits including protection against osteoporosis, heart disease, colon cancer, and possibly Alzheimer’s disease (“Hormone replacement therapy,” 2000). Treatment Issues The absolute contraindications for HRT often include estrogen-responsive breast cancer, endometrial cancer, undiagnosed abnormal vaginal bleeding, active thromboembolic disease, and a history of malignant melanoma (Cutson & Meuleman, 2000). The relative contraindications for the use of HRT include chronic liver disease, severe hypertriglyceridemia, endometriosis, previous thromboembolic disease, and gallbladder disease (Cutson & Meuleman). The side effects of HRT are attributed to the estrogen component and may include headache, nausea, breast tenderness, bloating, leg cramps, irregular vaginal bleeding, and increased vaginal mucus (Ammer, 1995). 9 P 1_ Estrogen loss is the primary cause of osteoporosis and is associated with an increased risk of fracture morbidity and mortality including hip and vertebral fractures. Long-term HRT results in a 30% to 50% reduction in all osteoporotic fractures (Cutson & Meuleman, 2000). The alternatives to HRT for bone protection include the use of bisphosphonate medications such as alendronate (Fosamax), risedronate (Actonel), and etidronate (Didronel) to maintain or increase bone mineral density and reduce fractures. Intranasal calcitonin (Miacalcin) inhibits osteoclast activity. In addition, raloxifen (Evista) is a selective estrogen receptor modulator that does not stimulate endometrial or breast tissue and does reduce fractures. Other nonhormonal and alternative therapies include the use of calcium and vitamin D supplements, weight bearing and strengthening exercises, smoking cessation, and decreasing alcohol intake (Cutson & Meuleman). The Rancho Bernardo Study was a cross sectional study of 740 women aged 60 to 98 years concerning osteoporosis (Schneider, Barrett-Connor, & Morton, 1997). The objective of the study was to determine the effect of initiation and duration of postmenopausal estrogen therapy on bone mineral density (BMD). The women were divided into groups based on HRT usage and length of treatment. The study concluded that estrogen initiated in the ear.ly menopausal years and continued into later life was associated with the highest BMD while estrogen started after age 60 years and continued into later life provided near.ly equal osteoporosis protection. It was demonstrated that BMD levels among current continuous users were 20% higher at the ultradistal radius. 12% higher at the midshait radius, 8% higher at the hip, and 13% higher at the lumbar spine when compmed to women who had never used HRT. Current late users had similar 10 findings when compared to women who had never used HRT with a 19% increase in bone density at the ultradistal radius, 10% at the midshaft radius, 7% at the hip, and 10% at the lumbar spine. Heart Disease. In American women, heart disease is the primary cause of death claiming 223,000 lives annually, and affecting one out of two women (Cutson & Meuleman, 2000). Estrogen has been shown to reduce the risk of heart disease 40% to 50% and reduce the relative risk of heart disease in one-third of the women who had ever used it. However, according to Cutson and Meuleman, HRT does not have any benefit for secondary prevention of cardiovascular events and may be only beneficial as primary prevention in otherwise healthy women. Other nonhormonal approaches for the prevention of cardiovascular disease include the prescription “statin” drugs such as atrovastatin (Lipitor) or simvastatin (Zocor) for women with dyslipidemia, as well as the use of aspirin to act as an anti-thromboembolic agent (“Hormone replacement therapy,” 2000). Alternative and nonpharmacological prevention measures include a diet high in fiber, low in fat, and rich in antioxidants; cardiovascular/weight bearing exercises; smoking cessation; and the use of relaxation techniques (Cutson & Meuleman). The Postmenopausal Estrogen/Progestin Interventions (PEPI) Trial (PEPI Trial Group, 1995) was a 3 year, multicenter, randomized, double-blinded, placebo-controlled trial of 875 healthy postmenopausal women aged 45 to 64 years with no known contraindication for HRT. The PEPI Trial subjects used estrogen without progestin or estrogen/progestin combinations. Estrogen with or without progestin improved lipoproteins. Estrogen alone resulted in a 5.6 tng/dL increase in high-density lipoprotein cholesterol (HDL). However, the increased risk of endometrial cancer restricts the use of 11 unopposed estrogen in a woman with a uterus. Estrogen/progestin combinations also showed a beneficial effect on HDL with an increase of 4.1 mg/dL. Mean low-density lipoproteins decreased 14.5 to 17.7 mg/dL with either estrogen or estrogen/progestin combmations. HRT was also noted to increase mean triglyceride levels 11.4 to 13.7 mg/dL. A randomized, blinded, placebo-controlled secondary prevention trail was conducted with 2763 women who had known coronary disease (Hulley et al., 1998). Their mean age was 66.7 years and all had an intact uterus. The objective of the Heart and Estrogen Replacement Study (HERS) was to determine, over a 4 year period, if HRT altered the risk for coronary heart disease events in postmenopausal women with known coronary artery disease. The results showed no significant difference between the placebo and HRT groups (relative hazard [RH], 0.99; 95% confidence interval [CI], 0.801.22). The study concluded that HRT did not reduce the overall rate of cardiovascular events but did increase the rate of thromboembolic events (RH 2.89; 95% CI, 1.50-5.58) and gallbladder disease (RH 1.38; 95% CI, 1.00-1.92). Therefore, HRT was not recommended as a means of secondary prevention in postmenopausal women with known coronary artery disease. A study by Parish et al. (1996) examined the effects of estrogen alone and in combination with progestin on lipoprotein risk markers for coronary heart disease. Eighty postmenopausal women were randomly assigned to received either estrogen with . or without progestin for 12 months while monitoring lipoprotein levels. Estrogen alone resulted in a slight rise in triglycerides and a decrease in low density lipoprotein (LDL) cholesterol significant at 6 months (^<0.05). There was a 16% increase in HDL (p<0.01), 12 while lipoprotein(a) showed no significant change. The combination of estrogen and progestin caused a 31 % decrease in triglycerides (p<Ml), 15% decr»e in totoi cholesterol (p<0.001), a 42% decrease in very low density lipoproteins (VLDL) (p<0.01), 9% decrease m LDL (p<0.05), and 11% decrease in HDL (p<0.001). Lipoprotein(a) was reduced 39 /o (p<0.05). Since at the end of 1 year the combination of estrogen and progestin had favorable effects on triglycerides, VLDL, LDL, and lipoprotein(a), these may balance the adverse effect on HDL. Colon Cancer. After age 50, there is a one in 19 chance of developing colon cancer with a one in 40 chance of fatality (Daminitz, McCormick, & Rex, 1996). Postmenopausal women using HRT are at a decreased risk since bile acids promote the development of colon cancer and estrogen and progestins reduce the production of those acids (Daminitz et al.). Alternative therapy for the prevention of colon cancer would include an aspirin every other day (Daminitz et al.), previous use of oral contraceptives, cessation of smoking, weight control, limited intake of red meat, and intake of folate (Grodstein et al., 1998). The Cancer Prevention Study II (CPS-II), which began in 1982 and ended December 31, 1989, followed 422,373 postmenopausal women who were cancer-free (Calle, Miracle-McMahill, Thun, & Heath, 1995). CPS-II demonstrated that any use of HRT was associated with a decreased risk of colon cancer with the greatest reduction in risk was among cunent user (RR, 0.55; 95% CI, 0.40 to 0.76) and with 11 or more years of use (RR, 0.54; 95% CI, 0.39 to 0.76). The Nurses’ Health Study was a prospective cohort and nested case-control study comprised of 59,002 postmenopausa! registered nurses ta. 11 U.S. states (Grodstein et 13 al., 1998). This study used biennial questionnaires from 1980 to 1994 and found that 470 women developed colorectal cancer and 838 developed distal adenomas. The current use of HRT was associated with a decreased risk of colon cancer (RR, 0.65; 95% CI, 0.50 to 0.83). This association declined with past use of HRT and was absent 5 years after HRT was discontinued (RR, 0.92; 95% CI, 0.70 to 1.21). The Nurses’ Health Study concluded that HRT decreased the risk of colon cancer, but this protection ceased when therapy stopped. A Wisconsin study identified women aged 30 to 74 years with a diagnosis of colon or rectal cancer through a statewide tumor registry (Newcomb & Storer, 1995). The study consisted of 694 case subjects and 1622 control subjects. Information on postmenopausal hormone replacement use as well as medical history was obtained via telephone interviews. Premenopausal women were excluded from the study. The researchers concluded that HRT provided a statistically significant reduced risk of colon cancer (RR, 0.54; 95% CI, 0.36 to 0.81), but had no effect on rectal cancer (RR, 0.91; 95% CI, 0.54 to 1.55). Alzheimer’s Disease. Alzheimer’s disease is the most common form of dementia and is a significant women’s health care concern since women live long enough to develop more severe cognitive impairment than men (Benson, 1999). Dementia of the Alzheimer’s type (DAT) affects three women for every one man. With the aging of the American population it is becoming a medical expense in excess of $1 billion dollars per year (Benson). The loss of estrogen is one contributing factor for DAT and, although HRT is not yet approved for the treatment of DAT, research has shown that HRT increases cerebral blood flow and may reduce the prevalence, incidence, and severity of 14 DAT as evidenced by improved memory, cognition, and Mini-Mental Status Exam scores when compared to women not taking HRT. A meta-analysis of ten studies of postmenopausal estrogen use and the risk of dementia was conducted to detei;rmine if estrogen therapy improved cognition, prevented the development of dementia, or improved the severity of dementia (Yaffe, Sawaya, Lieberburg, & Grady, 1998). The study results demonstrated a 29% decreased risk of developing dementia with estrogen use. However, studies of estrogen therapy in women with Alzheimer’s disease have had small samples, have been of short duration, and were generally uncontrolled. These studies indicated that estrogen might lead to improved cognition, reduced risk for dementia, or improvement in the severity of dementia, but further, long-term studies are needed before estrogen can be recommended for the prevention or treatment of Alzheimer’s disease or other dementias (Yaffe et al., 1998). The Baltimore Longitudinal Study of Aging also investigated the relationship between estrogen use and the risk of developing Alzheimer s disease (Kawas et al., 1997). This was a prospective multidisciplinary study of normal aging conducted by the National Institute on Aging and included 472 postmenopausal or perimenopausal women followed for up to 16 years. Estrogen use was documented, via either the oral or transdermal routes, and the Cox proportional hazards model with time-dependent covariates was utilized to determine the risk of developing Alzheimer’s disease. Forty- five percent of the women in the study were using estrogen replacement therapy. Thirtyfour cases of Alzheimer’s disease were diagnosed; nine of these women were using estrogen replacement therapy The study results demonstrated a reduced risk of 15 Alzheimer’s disease for women who use estrogen replacement (RR,0.46; 95% CI, 0.209 to 0.997). This study also recommended randomized clinical trails for further study. er. The fear of cancer is one of the most common reasons women refuse or discontinue HRT (“HRT 2000,” 2000). Many women believe that breast cancer is the leading cause of death in women when, iin fact, the chance of getting breast cancer is one in 17 by age 65 as opposed to one in three by age 65 for heart disease. Unopposed estrogen replacement therapy (ERT) should be taken only by women who have undergone a hysterectomy since unopposed estrogen use carries a five to eight times increased risk of endometrial adenocarcinoma (Cutson & Meuleman, 2000). HRT, a combination of estrogen and progestin, is prescribed for women with an intact uterus. In one study, combination HRT with estrogen and progestin was found to have a 24% increased risk of breast cancer for every 5 years of use, which correlates to an increased risk of 51% after ten years (Ross, Paganini-Hill, Wan, & Pike, 2000). The Nurses’ Health Study examined the relationship between current and past HRT use and the risk of breast cancer (Colditz, Stampfer, Willett, Hennekens, Rosner, & Speizer, 1990). This was a prospective study of 121,700 female nurses 30 to 55 years of age that were followed over a 6 year period. The Nurses’ Health Study showed that the risk of breast cancer was highest among current HRT users (RR, 1.36; 95% CI, 1.11 to 1.67). This study also demonstrated that no elevated risk was associated with past use and that a definitive answer relating to breast cancer has yet to be determined. A cohort study of follow-up data for 1980 to 1995 from the Breast Cancer Detection Demonstration Project was conducted to determine whether there is an increased risk of breast cancer with estregen-progestin combination compared to estrogen 16 alone (Schairer, Lubin, Troisi, St„rge()n, Brinton- & comprised of46,355 postmenopausal women, with ag e of 58 years, who were located at 29 screening centers throughout the United States. During thel5 year follow up, 2,082 cases of breast cancer were identified. The study concluded that there is a slightly greater risk of breast cancer with estrogen-progestin (RR, 1.4; 95% CI, 1.1 to 1.8) as opposed to estrogen alone (RR, 1.2; 95% CI, 1.0 to 1.4). The Iowa Women s Health Study in 1986 was a prospective cohort study of 37,105 postmenopausal women aged 55 to 69 years (Gapstur, Morrow, & Sellers, 1999). The study was conducted to determine associations between HRT use and breast cancer with favorable histology. These women were followed over 11 years with a total of 1520 cases of breast cancer. For HRT use of 5 years or less there was an increase in invasive carcinoma with favorable histology (RR, 1.81; 95% CI, 1.07 to 3.07) as opposed to HRT use of greater than 5 years (RR, 2.65; 95% CI, 1.34 to 5.23). There was no association between HRT use and the incidence of ductal carcinoma in situ or invasive ductal or lobular carcinoma which have a less favorable histology. The study concluded that HRT use was most strongly associated with an increased risk of breast cancer with favorable histology and prognosis. A population-based case-control study was conducted in King County in Washington State to determine the risk of breast cancer in relation to the use of HRT (Stanford et al., 1995). The participants were 50 to 64 years of age consisting of 537 patients with primary breast cancer and 492 randomly selected control women without a history of breast cancer. Menopausal hormones hod been used by 57.6% of the breast cancer patients and 61.0% of the control gt»»p. In this study, the women taking HRT 17 (21.5% of the breast cancer patients and 21.3% of the control group) were not at an increased risk of breast cancer (relative odds [RO], 0.9; 95% CI, 0.7 to 1.3). When compared with nonusers of HRT, those women who used HRT for 8 years or longer had a reduced risk of breast cancer (RO, 0.4; 95% CI, 0.2 to 1.0). The study concluded that in middle-aged women, the use of HRT does not appear to be associated with an increased risk of breast cancer, but further long-term studies need to be conducted. Summary Short term HRT therapy is indicated for the treatment of symptoms during the perimenopausal period (Cutson & Meuleman, 2000). The many benefits of long-term HRT use, primarily a decreased incidence of osteoporosis, improved lipid profiles, decrease incidence of colon cancer, and possible reduced risk of dementia of the Alzheimer’s type, must be weighed against potential health risks such as breast cancer. Alternative therapies for nonhormonal treatment are available but have not been studied for their long-term effectiveness or safety. 18 Chapter 3 Methodology The purpose of this scholarly project was to construct a web page designed for patient education related to hormone replacement therapy (HRT). The purpose of the web page was to assist perimenopausal and postmenopausal women in making an educated and informed decision as to the potential health benefits and perceived risks of HRT. This chapter discusses the development of the web page using Dreamweaver 3.0 software by Icon Logic, factors influencing patient education, and the Evaluating Printed Education Materials (EPEM) model by Bernier and Yasko (1991). Development of a Web Page To develop a web page, appropriate software must be utilized. For this project, Dreamweaver 3.0 by Icon Logic was used beginning with a site folder (Siegel, 2000). Once information, graphics, and links were entered into the site folder, it was submitted to an Internet Service Provider where the site is stored on their network for internet access. The codes for searching the web include ERT, HRT, hormones, hormone replacement therapy, menopause, perimenopause, hot flashes, estrogen, and progesterone. The font will be Tahoma with the majority of print at twelve point. The color scheme is predominately grayscale with color graphics. Factors Influencing the Adult Learner Several factors influence adults’ participation in the educational process: attitudes toward learning, life transitions, the importance of goals and their expectations for meeting goals, information related to learning opportunities, and perceived barriers toward learning opportunities (Whitman, Graham, Gleit, & Duncan Boyd, 1992), Perimenopausal and postmenopausal women are affected by these factors when deciding to use HRT. For example, negative attitudes toward learning will prohibit effective education reiating to HRT, However, during this life transition, individuals often express 19 the desire to increase their knowhdge (Whitmi„ M fa.e goal attainment might also fecihtate learning. The opportunity to educate patients is enhanced by educational material, including pamphlets and the internet. By increasing the ease of obtammg information, the patient may be more willing to participate in learning. The Neuman Systems Model (Neuman, 1995) demonstrates how sociocultural, developmental, and psychological factors influence a patient’s health maintenance decision. Sociocultural variables measure the relationship the patient has with family, friends, significant others, and community members (Reed, 1993). For example, a patient’s economic level may influence her health practices, beliefs, and lifestyle. These factors must be taken into account when developing a plan of treatment. Additionally, teaching plans must consider language, culture, and the methods of learning that are appropriate for the patient. The developmental variable in Neuman’s model measures cognitive abilities, education, and life experiences. The patient’s developmental age must be taken into consideration as well as the ability to conceptualize and respond to changes in health status (Reed). The psychological variable encompasses the mental and emotional aspects of the patient. Model for Evaluating Printed Education Materials To develop the web page, Bernier and Yasko's (1991) EPEM mode! was applied. The model consists of five phases: predesign, design, pilot test, implementation, and evaluation. Pmdesion. The predesign phase included the assessment of the need for information by perimenopausa! and postmenopausal women regarding hormone replacement therapy. The decision to start HRT wUl. in a.l probability, depend upon their 20 perceptions of potential health risks versus health benefits, information related to side effects, and alternative therapies. This needs to be made available from a reliable source. The purpose of the web page is to provide this information. Design. The design phase involved the review of literature to determine the information to be placed on the web page. This information was then combined with graphics and presented so that patients, capable of reading and understanding the English level at the eighth grade level, would comprehend the material. Links to other sites allow the patient to research related topics and to find information at a higher learning level. The McLaughlin Smog Formula (McLaughlin, 1969) was used to determine that the web page reads at an eighth grade. The formula is based on counting 10 consecutive sentences from the beginning of the web page, 10 consecutive sentences from the middle, and 10 consecutive sentences from the end. From these 30 sentences, the words containing three or more syllables are counted and the nearest perfect square root is determined. To this number, a constant of 3 is added to determine the grade level. For the eighth grade level, the word count will be 21 to 30, with the nearest perfect square root being 5. Pilot Test. The pilot test phase was completed by having the web page viewed by two health care professionals and three postmenopausal women. The web page was analyzed for clarity. content, and helpfulness of information and provided Mm. Changes were made to graphics (floral design) on the HRT home page, explmtadons of test questions were simplified, and ciarification concerning the indications for Evista was added. 21 Implementation/Distnbution. This informational site was made available via the world wide web and can be viewed by anyone with internet access. Information can be downloaded and/or printed and supplied to any perimenopausal or postmenopausal women requesting information on HRT. Evaluation. The evaluation of the completed web page can be done by asking anyone viewing the web page to respond to the web master via e-mail relating to the effectiveness of the information provided. Changes to the site can be made based on their responses and on new research findings concerning HRT. Summary In summary, the purpose of this scholarly project was to create a web page to be utilized by perimenopausal and postmenopausal women as a means of patient education on hormone replacement therapy. The web page address is www.velocitY.net/~rnnartm. The site was developed using Dreamweaver 3.0 software by Icon Logic. Development and evaluation of the site was done using the EPEM model by Bernier and Yasko (1991) and the McLaughlin Smog Formula (1969). 22 References c- <1995>- (3rd ei).

One in three women will die of coronary heart disease. Heart disease is, by far, the leading killer of women 55 and older. 2 In the female body, estrogen is responsible for the development of female breasts. a. true b. false At the onset of puberty, estrogen stimulates the development of characteristics such as rounded hips and breasts. Estrogen also plays an essentia, pad in menstruation, being response for the month,,Ranges in the lining of the womb. As a woman grows older, her ovanes smaller amounts of estrogen as "change of life" begms. 31 3 Menopausal symptoms, such as hot flashes and night sweats, last for the rest of a woman's life. a. true b. false For most women, the symptoms of menopause last for a relatively short time. However, a woman's level of estrogen always remains low after menopause. This can affect many parts of the body including the sexual and urinary organs, the heart, and the bones. 4 Memory can be affected by menopause. a. true b. false Many menopausal women have problems with short-term memory because of low estrogen levels. It is not unusual to forget things like appointments or losing the end of a thought when speaking. 5 Hormone replacement therapy (HRT) relieves many of the symptoms associated with menopause. a. true b. false One immediate benefit of hormone replacement therapy is the relief of uncomfortable symptoms that may occur with menopause; things such as "hot flashes" (a wave of heat and sweating), night sweats, and painful intercourse. Hormones also help alleviate other menopausal symptoms, such as changes in urination, irritability, and depression. 6 HRT is risk free. a. true b. false There are some risks associated with the long-term use of HRT. These risks depend on the type of treatment prescribed, whether the woman has a uterus, and how long the hormones are taken. There are almost no risks 32 associated with a short-term therapy of less than five years. 7 Every woman experiencing menopause may use HRT. a. true b. false Not every woman is a candidate for HRT. Women with a family history of breast cancer as well as women who have had breast cancer, abnormal vaginal bleeding, liver disease, or blood clots should be carefully evaluated before hormone replacement therapy begins. 8 HRT is used by postmenopausal women. a. true b. false For healthy women, long-term use of HRT is often recommended to slow bone loss, decrease the risk of bone fractures, prevent heart disease, and reduce the risk of colon cancer. 9 For most women, the benefits associated with HRT outweigh the risks. a. true b. false There is almost no short-term risk. Long-term risks that accompany HRT include a small increased tendency toward blood clots in the veins and a small increase in the risk of breast cancer. However, studies indicate that the breast malignancies associated with HRT may be of a less aggressive type than those discovered in postmenopausal women not using HRT. 10 HRT usage is rare. a. true b. false HRT usage is not rare. About 12 million women in the United States take estrogen alone while another 8.6 million women are on the combined estrogen and progestin regimen, according to drug company estimates. 33 As Women Age From the main menu, clicking on “As Women Age” produces a web page that contains the text below: As women age they eventually experience menopause, commonly referred to as "change of life." It is characterized by irregular menstrual periods and decreases in the amount of estrogen produced by the body. This condition generally affects women between the ages of 40 and 60 years. This time period may be characterized by hot flashes, night sweats, sleep disturbances, vaginal dryness, changes to the skin, fatigue, irritability, forgetfulness, and headache. Perimenopause symptoms may precede the end of menstruation by one or two years. What is happening within the body? The natural estrogen produced in the ovaries of a woman not only allows her to have children, but also helps keep her bones strong. As will be seen, there is evidence that estrogen also protects against heart disease and stroke. During the perimenopausal phase, the estrogen level gradually decreases which causes the risk of heart and blood vessel disease to slowly rise. By the time menstrual periods finally end, estrogen levels will have been reduced significantly. What if 1 had a hysterectomy? According to the American Heart Association, if the menstrual periods are brought to an abrupt stop through the surgical removal of the uterus, the chance of heart and blood vessel disease sharply increases. Can anything be done to control the symptoms associated with menopause? Cutson and Meuleman report that replenishing estrogen levels may alleviate depression and the constant feeling of illness or discontent. Estrogen also improves concentration and decreases the sensation of hot flashes, urethral irritation, vaginal thinning, and painful intercourse. 34 Heart disease is the number one killer among women. What effect does HRT have on heart disease? The American Heart Association states that over the years, millions of women have been given estrogen to relieve the symptoms associated with perimenopause and to lessen the risk of heart and blood vessel disease. For women who have not had a hysterectomy, the estrogen is combined with another hormone called progestin. For women that have had a hysterectomy, the progestin is unnecessary and they are given estrogen alone. May HRT be continued beyond the time when I no longer have periods? Yes. According to Gambrell, taking estrogen continues to offer protection against osteoporosis, heart disease, colon cancer, and possibly Alzheimer's disease long after menopause and even into very old age. What risks are associated with hormone replacement therapy? At the center of the HRT controversy is the debate concerning perceived risks versus benefits. For women who take HRT for less than five years, there is almost no risk involved. For long-term users, there seems to be a slight increase in risk of breast and uterine cancers in some individuals, and there may be a slight tendency to form blood clots. Some women have discontinued HRT because of breast tenderness, vaginal bleeding, and the fear of developing cancer or blood clots. To see a more complete discussion of the benefits and risks associated with HRT, click on the "HRT Issues" button at the left. How do I decide whether HRT is right for me? Begin by becoming well-informed. Read as much as you possibly can about HRT and estrogen replacement therapy. This web is a good starting point. Once you are knowledgeable, discuss the possibility of using hormone therapy with your health care provider who will assess your history and current health. On this basis, you and your health care provider can determine if the potential benefits associated with HRT outweigh any risks. 35 HRT Issues From the main menu, clicking on “HRT Issues” produces a page that serves as an introduction to the various HRT issues to be discussed. Hormone Replacement Therapy is used to effectively manage the symptoms associated with menopause. Used long-term, it also offers significant protection against osteoporosis and heart disease in women, decreases the risk of colon cancer, and may even offer some protection against Alzheimer's disease. Medical science has identified estrogen loss as the cause of "change of life" symptoms. Today, replenishing this lost estrogen is a simple and effective process with a variety of prescription medications available - - much more attractive than the use of leeches, a method used 200 years ago! The decision to use HRT should be made on the basis of maintaining wellness and promoting long-term health. In the face of this decision, a woman should understand the risks as well as the benefits associated with this therapy. This page introduces a new menu. A “Home Page” button may be clicked to return to the original menu. 36 Osteoporosis Clicking on “Osteoporosis” from the “HRT Issues” submenu produces this Page. The word osteoporosis means "porous bones." The bones become brittle as this disease progresses. Women are particularly susceptible to osteoporosis. It may begin even before menopause, but the effects of the disease increase dramatically as a woman's estrogen level declines. Postmenopausal women are at great risk from osteoporosis. The skeletal system fractures easily when osteoporosis is in an advanced stage. The top image at the right shows bone that is becoming diseased. The dark areas represent no bone growth. At the left is an image of a more advanced form of osteoporosis in the same region. Notice the obvious decrease in bone. A region with this type of bone loss is very susceptible to fractures. Such fractures typically occur in the areas of the hip, wrist, and vertebrae. The lower image to the right shows a vertebral fracture. Cutson & Meuleman have demonstrated that HRT, when used long-term, results in at least a 50% reduction of osteoporotic bone fractures. May a woman obtain significant osteoporotic benefits if HRT is started later in life? The Ranco Bernardo Study involved 740 women aged 60 to 98 years. The study concluded that estrogen initiated in the early menopausal years and continued into later life resulted in the greatest bone strength. But, the study also found that women who started HRT after age 60 obtained nearly the same amount of protection against osteoporosis. 37 Heart Disease Clicking on “Heart Disease” from the “HRT Issues” submenu produces this page. The following statement may come as a bit of a shock: recent findings show that twice as many women die from heart disease than from all forms of cancer combined! Furthermore, an important part of this heart disease is the diminishing supply of estrogen as women age. Elevated levels of cholesterol in the blood can cause heart disease. There are different types of cholesterol within the body. High levels of LDL cholesterol (Low Density Lipoproteins - the "bad cholesterol") are responsible for the formation of fatty deposits along the inside walls of the arteries. This causes blockages in the arteries that often lead to serious heart disease. On the other hand, HDL cholesterol (High Density Lipoproteins - the "good cholesterol") transports excess blood cholesterol to the liver where it is recycled or eliminated. As a result, increasing the HDL level protects against coronary heart disease. Several studies have shown the important role that estrogen replacement plays in lowering the risk of heart disease. The Postmenopausal Estrogen/Progestin Interventions Trial (PEPI Trial) was an extensive threeyear study involving women between the ages of 45 and 64 years. The study found that the use of estrogen significantly lowered LDL levels and significantly elevated HDL levels. In all, HRT was demonstrated to be effective in lowering the risk of heart disease in healthy women even though HRT does elevate triglycerides to some extent. Cutson and Meuleman claim that HRT may reduce the risk of heart disease by 40% to 50%. The Heart and Estrogen Replacement Study (HERS) was a four year study that concluded that HRT provided no protective effect in women who already had heart disease. 38 Colon Cancer Clicking on “Colon Cancer” from the “HRT Issues” submenu produces this Page. The colon or large intestine (pictured in purple) has five parts: from the lower right side of the body, the Ascending Colon extends upward to the Transverse Colon which extends across the abdomen to the left side; the Descending Colon extends downward to a lower S-shaped piece of large intestine called the Sigmoid Colon which empties into the Rectum, a container that is vertical and approximately seven inches in length. The Anus is the opening to the outside. Colon cancers typically begin as benign polyps in the large intestine. They can be detected and removed before they become cancerous. Through colonoscopy or sigmoidoscopy, flexible scopes equipped with a light and tiny camera are used to examine the colon. Adults should have such an exam every five years to prevent colon cancer. Acids formed in the liver (bile acids) promote the development of colon cancers. A study done by Daminitz, McCormick, and Rex, determined that postmenopausal women using HRT are at a decreased risk for colon cancer since estrogen and progestin reduce the production of these bile acids. The eight year Cancer Prevention Study II (CPS-II) demonstrated that any use of HRT was associated with a decreased risk of colon cancer. These results were also confirmed by the Wisconsin Study. Even though these results indicate a significantly reduced risk of colon cancer, the use of HRT seems to have no effect on the frequency of rectal cancer. 39 Breast Cancer Clicking on “Breast Cancer” from the “HRT Issues” submenu produces this page. The relationship between the risk of breast cancer and HRT remains a concern. Many women believe that breast cancer is the leading cause of death in women when, in fact, the chance of getting heart disease by age 65 is six times greater. Periodic mammograms are recommended for early detection of breast cancer. There have been many studies, some that show HRT increases the risk of breast cancer and others showing that HRT does not increase this risk. A 1995 study conducted in King County in Washington State concluded that middleaged women taking HRT were not at an increased risk for breast cancer. The Breast Cancer Detection Demonstration Project (BCDDP), a national breast cancer screening program that involved 46,355 postmenopausal women, found an increased risk of one percent each year for women taking estrogen only; they found an eight percent increase in breast cancer risk each year for women using the estrogen-progestin combination. For someone taking the combination estrogen-progestin over ten years, there may be an increase in the risk of developing breast cancer. As a result of the BCDDP, the National Cancer Institute advises women with no uterus to avoid long-term combination therapy; however, the Institute also states that the combination therapy poses no additional breast cancer risk for any woman if used for only a few years to alleviate the symptoms associated with menopause . Because of the conflicting data regarding the risk of breast cancer and long-term use of HRT, the National Cancer Institute is continuing this research and is soon to gather and study new data. 40 Alzheimer’s Disease Clicking on “Alzheimer’s” from the “HRT Issues” submenu produces this page. Alzheimer's disease is the most common form of dementia and is a significant health concern for women since women live long enough to develop it more often than men. According to Benson, dementia of the Alzheimer's type affects three women for every one man. Very little is known about the cause and currently there is no cure. In fact, the disease can be identified with absolute certainty only by autopsy after death. Scientists are currently exploring the effect of estrogen in the prevention of Alzheimer's disease. It seems that estrogen may slow the formation of the plaque produced by the disease, and improves blood flowthrough the brain. In an analysis often studies by Yaffe, it was determined that postmenopausal estrogen use decreased the risk of Alzheimer's disease by 29%. However, the studies involved small groups of women for short periods of time. Therefore, the results are not completely reliable. The Baltimore Longitudinal Study of Aging (BLSA), conducted by the National Institute on Aging, included 472 older women that were followed for 16 years. This well-controlled study demonstrated a significantly reduced risk of Alzheimer's disease for women who use HRT. 41 Alternative Therapies From the main menu, clicking on “Alternative Therapies” produces a web page that contains the text below: The alternative approaches to HRT usually focus on dietary, nutritional, and lifestyle changes. They may include prescription drugs or nonprescription drugs other than estrogen/progestin. Many of these alternatives to HRT involve a risk of their own since very few have been studied for either their long-term effect or their safety. The motivation for using these therapies is usually to avoid the risks associated with HRT therapy. Sometimes this approach is very effective; in any case, it requires both great discipline and patience. A generally healthy lifestyle is advocated which stresses good nutrition and exercise, the elimination of smoking, and a decrease in alcoholic consumption. Of course, this should be everyone's lifestyle. The General Relief of Menopausal Symptoms The Association of Reproductive Health Professionals heard testimony stating that the natural progesterone present in yam root, taken orally as Prometrium and used to provide relief of various menopausal symptoms, is no more effective than a sugar pill. However, some alternative therapies are recognized as being somewhat effective. Specific dietary and nutritional changes with nutritional and herbal supplements have been shown to alleviate some menopausal discomforts. For example, soy protein may reduce hot flashes, bone loss, and LDL-cholesterol levels. Osteoporosis As a non-hormonal therapy, calcium is typically recommended to prevent bone loss in women. With increased doses, and combined with vitamin D, calcium does seem to provide some protection. Numerous studies have shown that 42 calcium alone does not build bone, but only slows bone loss. Fosamax is another drug prescribed to improve bone density. The manner in which Fosamax and other drugs of its type (biophosphates) slow the progression of osteoporosis is not completely understood. Most endocrinologists prefer the use of estrogen to biophosphates. Calcitonin, a hormone naturally produced in the thyroid and prescribed for patients with osteoporosis, is a prescription drug that produces modest increases in bone mass. This drug is sprayed into the nose for quick absorption into the blood stream. It is less effective than estrogen. Combining calcitonin and estrogen, with enough calcium (1,200 mg a day), offers an even greater benefit than using either separately. Evista is another prescription drug that is used to prevent bone loss. It has no effect on uterus or breast tissue and it does reduce osteoporotic fractures. However, it cannot be taken by everyone. If you can become pregnant, are nursing, have severe liver problems, or have had blood clots that required a doctor's treatment, you cannot take Evista. Also, Evista cannot be started while a woman is still experiencing hot flashes or the symptoms will worsen. Heart Disease Vitamin E is frequently taken to reduce the risk of heart disease. Researchers from the National Heart, Lung and Blood Institute concluded in January, 2000 that estrogen provides more effective heart protection than vitamin E . Currently, other studies are in progress to better determine the role of both estrogen and vitamin E in preventing heart disease in postmenopausal women. Typical measures taken to prevent heart disease include exercise, daily aspirin, and a diet that is low in fat, high in fiber content, and rich in antioxidants. For women with high cholesterol, prescription drugs such as Lipitor and Zocor are often used. When these drugs are taken, periodic blood tests are required to 43 check liver function. Other prescription medications such as Baycof and Pravachol are also available to combat cholesterol problems. Colon Cancer According to the Harvard Center for Cancer Prevention, men and women are at equal risk for developing colon cancer. To lower colon cancer risk, eat less red meat, exercise regularly, take multivitamins that contain folic acid, aspirin 325mg every other day, vitamin E and get screened regularly after the age of 50. The risk of dying from colon cancer is reduced about approximately 50% with periodic screening. In Conclusion... There is a wide variety of alternatives to HRT. These alternatives range from acupuncture to herbs and include prescription as well as nonprescription drugs. The above discussion refers to some of the more popular alternative therapies. Keep in mind that very little testing has been done to determine the actual effectiveness of most of these non-pharmacological (or prescription drug) alternatives. Of course, HRT is also not completely risk free. The benefits of HRT are many.
