Contraception, Sterilization and Abortion Alternatives, Counseling and Management Suzanne Trupin, MD Women’s Health Practice Clinical Professor of Obstetrics and Gynecology Contraceptive Practices in USA The typical American woman wants only two children; she spends roughly five years pregnant or trying to become pregnant, and three decades trying to avoid unwanted pregnancy. Yet many women find it difficult to practice contraception consistently or correctly over the course of their entire reproductive lives and lack the information and services that would assist them in doing so. As a result, roughly one in three American women will have had an abortion by age 45. Counseling: GATHER Greet the patient in a warm and friendly manner, help her to feel at ease (Gather information on what she knows) Ask the patient about her needs and goals, STI risks nondirective counseling improves outcomes Tell the patient about her choices Help her decide Explain the correct use of the method or drug being prescribed Repeat important instructions and set up Return appointments World Population Growth Oct 12th 1999 we reached 6 billion, US just reached 300 million this year Mourning Picture for Polly Botsford and Her Children (c. 1813) Medical Evaluation for Contraception Prescription: WHO Class A: Mandatory Pelvic for IUD, Cervical Cap and Diaphragm, Sterilization STI risk for IUD BP screening for women getting sterilization Class B: Contributes substantially to safe and effective use, but consider context Hb for IUD and Sterilization Class C: does not contribute substantially to safe and effective use of the method U.S. Pregnancies: Unintended vs. Intended Intended 51% Unintended 49%: Unintended births 22.5% Elective Abortions 26.5% Henshaw: Fam Plann Perspect 1998;30:24-29.

Categories of Contraceptive Risk WHO Category 4 (old ‘contraindications’, now ‘refrain from use’) Condition which represents an unacceptable health risk if the contraceptive method is used. Do not use the method. WHO Category 3 (exercise caution) A condition where the theoretical or proven risks usually outweigh the advantages. Use of method is not usually recommended WHO Category 2 (advantages outweigh risks) Generally use the method with clinical judgement WHO Category 1 (no restrictions) Use of Contraception with Coexisting Medical Conditions FDA package labeling is the same for POP as COC without supporting evidence in many cases Current labeling for Norethindrone POP no longer lists history of thromobembolism as contraindication but does for norgesterel POP Conditions that expose a woman to increased risk as a result of unintended pregnancy Breast cancer or Estrogen Dependent Neoplasia Complicated valvular heart disease Diabetes: Vascular Complications WHO Category 4 most apply to COC, R, P Known thromobegenic mutations do not use COC or CIC Uterine Fibroids with cavity distortion do not use Cu-IUD or LGN-IUD PID or purulent cervicitis or active GC or CT do not Initiate IUDs For conditions of high risk of HIV and AIDS spermacide use is a category 4 Cerebrovascular or coronary artery disease multiple risk factors Migraines with Aura or migraines over the age of 35 Lactation (<6 weeks postpartum) do not use COC, P, R Liver disease Headaches with focal neurologic symptoms Major surgery and prolonged immobilization Age >35 years and smoke >14 cigarettes per day or more do not use COC, P, R Hypertension (blood pressure of >160/100 mmHg or concomitant vascular disease) Venous thromboembolism history Major surgery with prolonged immobilization WHO Category 3 (exercise caution) Postpartum <21 days Lactation (6 weeks to 6 months) Age >35 years and smoke <15 cigarettes per day History of breast cancer but no recurrence in past 5 year Interacting drugs (that affect liver enzymes) Gallbladder disease WHO Category 2 (advantages outweigh risks) CIN Severe headaches after initiation of oral contraceptive pills Undiagnosed vaginal or uterine bleeding Diabetes mellitus Major surgery without prolonged immobilization Sickle-cell disease or sickle-cell hemoglobin C disease Blood pressure of 140/100 to 159/109 mm Hg Undiagnosed breast mass Obesity Age >40 years High BP in Pregnancy Conditions predisposing to medication noncompliance Family history of lipid disorders Family history of premature myocardial infarction or DVT Uncomplicated valvular heart disease WHO Category 1 (no restrictions) Postpartum >=21 days Pos-tabortion, with abortion performed in first or second trimester History of gestational diabetes Varicose veins Mild headaches Irregular vaginal bleeding patterns without anemia Past history of PID Current or recent history of PID Current or recent history of STD Vaginitis without purulent cervicitis Increased risk of STD HIV-positive or at high risk for HIV infection or AIDS Benign breast disease Family history of breast cancer or endometrial or ovarian cancer Cervical ectropion Viral hepatitis carrier Uterine fibroids Past ectopic pregnancy Thyroid conditions Oral Contraception Oral Contraceptives and Shorter Acting Steroid Contraception Contraceptive Cases A 16 year old wants pills but refuses a pelvic, do you give them to her? 19 year old U of I sophomore says her menses comes on Sunday, so she wants to know does she start this Sunday or next?

Decrease No Increase Change Intrauterine Contracetion IUD IUS IUC Contraceptive Case A patient wants to get her pap and her IUD but the nurse insists she come on her period for the IUD insertion, who is right? A 29 year old exotic dancer comes for an IUD insertion, her most frequent partner has offered to pay for it, do you recommend this method for her? The nurse asks you if you want to give the patient antibiotics before or after IUD insertion? A patient wants to know fertilization rates with IUDs? IUC History Guidelines overly restrictive in the past. These obsolete recommendations reflected concerns about infection and resultant infertility. This cloud of suspicion concerning infection has now been lifted from the IUD by data from both cohort and case-control studies. A landmark case-control study from Mexico City showed that among nulligravid women, use of a copper IUD was not associated with tubal infertility; in contrast, prior exposure to Chlamydia trachomatis was associated with a significant increase in risk.[1] Cohort studies from Norway[2] and New Zealand[3] have found that upon discontinuation of an IUD, women had problems with unwanted fertility, not involuntary infertility. Almost any woman interested in highly effective contraception can use an IUD. IUDs today are appropriate for women who have never been pregnant as well as for those who have had upper genital tract infection or a prior ectopic pregnancy. For example, the World Health Organization Medical Eligibility Criteria give nulliparity a category 2 rating, meaning that, in general, the benefits of IUDs for such women outweigh the potential harms. A few contraindications exist, such as an established pregnancy, undiagnosed uterine bleeding that might represent cancer, mucopurulent cervicitis, etc. Leukocytic Infiltration of Superficial Layers of Endometrium in Contact with IUD: Day 16 of Cycle LNG-IUS (Mirena®) Contraceptive efficacy due to cervical mucus change and sperm motility and function inhibition plus weak foreign body action. 20 mcg/d LNG (30 would suppress ovulation). 5 year cumulative failure rate 0.71/100 in 12,000 US women.

According to both the scientific community and long-standing federal policy, a pregnancy is established when a fertilized egg has implanted in the wall of a woman’s uterus. However, definitions of pregnancy in state law vary widely. And although they have not yet been used to impede women’s access to legal hormonal contraceptive methods, such restrictions are a goal of at least some antiabortion and anticontraception activists. To date, 22 states have enacted one or more laws that include a definition of “pregnancy.” The definitions found in 18 of these laws are based on the idea that pregnancy begins at fertilization or conception. The ongoing debate around emergency contraception–a concentrated dosage of the same hormones found in birth control pills–has brought the question of when pregnancy prevention ends and disruption of an existing pregnancy begins to the forefront of public discussion. Attempts to define pregnancy as beginning before implantation could have serious implications for women’s access to both emergency contraceptives and other hormonal contraceptive methods. “The fact is the majority of Americans have sex before marriage; virtually all U.S. women (98%) use a contraceptive method at some point in their lives; and most women rely on contraception, not abstinence, to help them responsibly manage their sexual lives in the long term,” says Dailard. “As long as politicians continue to ignore the realities of women’s lives, the United States will continue to have the highest rates of unintended pregnancy and abortion in the developed world–a dubious honor that most Americans would prefer not to have.” (Contraceptive) Case A 21 year old patient presents for an abortion but she doesn’t have a positive pregnancy test, she wants a medical abortion, what do you give her? Medical Abortion Regimens Prostaglandin Mifepristone + Antiprogesterone Misoprostol Antimetabolite Methotrexate + Misoprostol Medical Abortion Advantages Can be performed without delay Avoids surgical and anesthetic risk Potential to increase access through expanding providers (not true) Potential to shield abortion providers (also not true) Increases choice Medical Abortion Disadvantages Longer waiting period for completion Requires multiple visits (2-3) Less effective than surgical (95% vs 99%) Not available after about 7 weeks Expense (Cumbersome) regimen Surgical Abortion Advantages More effective Shorter time to completion Fewer visits Shorter bleeding duration Always has pathologic confirmation Can be performed in later gestation Surgical Abortion Disadvantages More serious risks involved Limited access Requires more equipment and investment Providers more vulnerable to risk Medical Abortion Counseling Desires termination of pregnancy Usual method and efficacy of alternatives Risks, side effects, tetarogenicity and adverse events for each medication and for failed medical Informed consent and administer the MifeprexTM Medication Guide and Patient Agreement Medical ascertainment of contraindications to the medications Clarify the amount of pain and the number of visits and the possibility of need for outside medical care at own expense Mifepristone: Mechanism Softens and dilates the cervix Causes decidual necrosis by affecting the capillary endothelial cells of the decidua and detachment of pregnancy Increases prostaglandin release Increases uterine contractions and sensitivity to exogenous prostaglandin Mifepristone + Misoprostol Medical history and physical exam Pregnancy dating (HCG titers if no sac) Rh status and administration of Rhogam Hematocrit or hemoglobin Counseling/informed consent Offer surgical abortion Explain 4 hour waiting requirements of visit 2?
