Breakout Session B - 2016 Charleston APRN Conference
Women’s Health Update 2016: A Sharmacological Review for APRN’s Kelly W. Jones, Pharm.D., BCPS Associate Professor of Family Medicine McLeod Family Medicine Center Florence, South Carolina kjones@mcleodhealth.org In Memory of Dr. Sharm Steadman Disclosure I have no conflict of interest relating in the material covered today I do not serve on any speaker bureau I do not have any personal grants concerning the area of discussion today 1 More Disclaimer I like bow-ties. No discussion of ties in this talk and how they could be conduits to infection. Just took a dose of ibuprofen to help my feet but we will not discuss NSAID’s. Used “Big Sexy Hair” hairspray this morning, but no discussion on hairspray! My shoe size is 10, but we will not discuss shoes today. Objectives 1) Discuss the history involving use of estrogen and progesterone for menopause. 2) Discuss the current research involving hormone therapy for the prevention and treatment of diseases associated with menopause. 3) Compare and contrast treatment regimens for hormone therapy. 4) Describe the components of oral contraceptives, comparing monophasic, biphasic and multiphasic products. 5) Discuss new oral contraceptives, identifying important side effects, clinical relevance and therapeutic usefulness. 6) Discuss new products and new indications. Recent News on Mammography New guidelines from the American Cancer Society Women 40-44 should discuss mammography with their provider and start screening if risk or wants warrant (insurance coverage?) Women 45 – 54 annual screening Women older that 55 – every other year, discontinue if life expectancy falls below 10 years (they use to recommend stopping at age 74) Clinical breast exam for screening is not recommended at any age JAMA 2015;314(15):1599-14 2 USPSTF Recommendation of 2009 Biennial screening mammography for women aged 50 to 74 years. The USPSTF recommends against routine screening mammography in women ages 40 to 49 years. The decision to start screening mammography should be an individual one and take patient context into account, including the patient’s values regarding specific benefits and harms. Women in their 40’s undergo excessive treatment and harm (false +, biopsies, surgery and chemotherapy) Hot controversy Excluded radiologist and oncologist Risking lives to reduce cost Harbinger for rationing and government-run health care USPSTF 2016 Guidelines Ann Intern Med 2016;164(4):279-96 USPSTF Grading 3 False-Positive Results USPSTF 2016 Guidelines Ann Intern Med 2016;164(4):279-96 What is the USPSTF? z z Established in 1984 Non-governmental y z z z y z z They do receive administrative support Independent Apolitical The members are nonfederal experts on preventative medicine and primary care They weigh patient benefit and harm They do not advise insurers Not cost-oriented Moral duty “When millions of asymptomatic women have a procedure that benefits few, the consequences of inaccurate mammograms to save one woman’s life is a legitimate ethical question for us to consider.” JAMA 2010;303(2):162-3 For most with cancer, screening does not change the ultimate outcome; the cancer is just as treatable or just as deadly regardless of screening. Ann Intern Med 2009;151(10):738-47 4 “Take the test, not the chance” Really? Benefit Women age 40 to 49 NNS = 2000 For every 2000 women screened for breast cancer with mammography 1 would be spared death from breast cancer over a 10 year period. NNS = 3400 for those in their 40’s and over 10 years (from recent 2015 JAMA editorial) Harm In that same 2000 women, 120 to 400 would get biopsy due to a falsepositive mammogram 2 to 10 would be overdiagnosed, resulting in tx 6 JAMA 2010;303(2):162-73 JAMA 2014;312(23):2585 Harms of Mammography 40% can have false-positive mammogram Overdiagnosis Cancers detected by mammography that were never destined to cause symptoms or death Because it is impossible to know who is overdiagnosed, all are treated Surgery, chemotherapy, radiation or some combination Besides treatment and harm, they must live with the fear of recurrence 5 Overdiagnosis Malmo trial 2 women are overdiagnosed for every breast cancer death avoided BMJ 2006;332(7543):689-92 Gotzsche, et al 10 women are overdiagnosed for every breast cancer death avoided Cochrane 2009;4:CD001877 Overdiagnosis – Definition Hypothetical study Overdiagnosis Zone 40 cases of overdiagnosis Life Expectancy Table JAMA 2015;314(15):1599-14 6 Breast Cancer Risk by Age JAMA 2015;314(15):1599-14 Self-Assessment Questions-T/F 1. 2. 3. 4. 5. 6. __ Hormone replacement therapy should be offered to most postmenopausal women to prevent heart disease. __ Hormone replacement therapy should be offered to most postmenopausal women to prevent osteoporosis. __ Hormone replacement therapy should be offered to most postmenopausal women to prevent breast cancer. __ Hormone replacement therapy should be offered to most postmenopausal women to prevent vasomotor symptoms. __ Antidepressants can be used to reduce hot flashes as an alternative to hormones. __ In those women who smoke, estrogen patches are the formulation of choice. 7 Hormones for what? Menopause is defines retrospectively after 12 months of amenorrhea Usual transition begins in the mid to late forties and last 4 years with menopause occurring at a median age of 51 years 6000 American women reach menopause every day 40% of a women’s life is spent in menopause Smokers, low BMI, nulliparity, lower education go through menopause 2 years earlier Med Clin N Am 2015;99:521-34 Science side of hormones Women live longer than men! Lowers cholesterol Lowers heart disease Increases bone mineral density and reduces osteoporosis Improved cognition in “Nuns” Hormones should reduce cancer, right? Therefore, HORMONE REPLACEMENT THERAPY Research • Yesterday • • Observational studies Today • • • • Evidence-based Medicine HERS Trial WHI Trials WHIMS Trial 8 The WHI trial have changed things Top 300 drugs by total prescriptions rxlist.com 1995 1996 1997 1998, 1999 2000, 2001 2002 2003 2004 2005 #1 #2 #2 #1 #3 #5 #16 #31 #46 Real Benefits of HT Hot Flashes or Flushes 80% of women are affected 20% find the symptoms intolerable The severity and frequency vary during the day or night. Hot flashes last ~4 min, can last 10 min Hot flush may or may not be associated with sweats May have chills Often aggravated by warm environment, stress, hot food and beverages Lancet 2005;336:409-21 Med Clin N Am 2015;99:521-34 Incidence Symptoms generally begin 2 years before true menopause, peak one year after menopause and diminish over next 10 yrs Usually transient 30% to 50% improve over a few months Most resolve within one year 90% have resolved by 5 years 10% can have hot flushes for many years. Med Clin N Am 2015;99:521-34 9 New Trial SWAN Longitudinal Database Longitudinal, observational trial spanning 17 years, USA trial Sought to assess the transition from premenopause into late postmenopause (menstrual transition) 42 to 52 year old women 13 visits from 1996 to 2013 (follow-up mean is 12.7 yrs) Used a questionnaire at each visit Started with 3302 cohort Excluded 1853 51% of these excluded women had NO visits with frequent vasomotor symptoms (VMS) JAMA Intern Med, published online Feb 16, 2015 SWAN Longitudinal Database Defined 2 groups Total VMS Duration (menstrual symptoms) Post-FMP Persistence (symptom persistence after final menstrual period) Patients in general ~50 years old Multi-racial (45% white, 35% AA) ~70% married, 60% with no financial strain, 40% > college education, 54% never smoked, ~35% with BMI > 30 10 SWAN Song Mean total VMS lasted 7.4 yrs Those who had a defined observable final menstrual period,VMS lasted 4.5 years Those with premenopausal symptoms (early perimenopausal) had VMS for the longest, median 11.8 years Those who were postmenopausal at the onset of VMS had the shortest duration, 3.4 years AA had the longest duration of symptoms, 10 years Longer duration was associated with younger age, lower education level, greater perceived stress and anxiety, depressive symptoms Efficacy data in hot flashes Meta-analysis data reveal a reduction in vasomotor symptoms 65% in estrogen only patients 90% in combined hormone patients Substantial efficacy is usually seen by 4 weeks. Low doses may take 8-12 weeks to work. NEJM 2006;355(22):2338-47 11 Symptoms Vasomotor symptoms Hot flashes Night sweats Vaginal symptoms Urinary incontinence Trouble sleeping Sexual dysfunction Depression, anxiety Labile mood Consistent association More Symptoms Memory loss Fatigue Headache Joint pain Weight gain NEJM 2006;355(22):2338-47 Urogenital symptoms Symptoms include Vaginal dryness and atrophy Dyspareunia Recurrent UTI Vaginal symptoms worsen with aging Hormones help with symptoms and are best used topically, but oral and transderm are also effective.

They are natural…. They may have less side effects So where are we? Back to the basics: treat symptoms and dis-ease more so than disease or disease prevention. Continuous-combined regimens have improved adherence. We have more options to start with: Prempro® or Activella® Femhrt® for estrogen-sensitive patients. Ortho-Prefest® for progestin-sensitive patients.
