Contraception, Sterilization and Abortion Alternatives, Counseling and Management Suzanne Trupin, MD Women’s Health Practice Clinical Professor of Obstetrics and Gynecology
Slide 2-

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

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)
Slide 12-

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
Slide 13-

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
Slide 14-

WHO Category 4most 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
Slide 15-

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
Slide 16-

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

Oral Contraception Oral Contraceptives and Shorter Acting Steroid Contraception
Slide 19-

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? To take a break from pills a 21 year old stops the pills for a month while her partner is off visiting medical schools. How long a break does she need? A 16 year old presents with her mother requesting pills for acne, the mother insists you give her the ones that are the cheapest, the patient wants the ones she sees on TV that are good for your skin, which do you choose? A 23 year old is getting monthly PMDD, what do you advise? A 55 year old comes in on birth control pills from her previous physician, is this dangerous? A 26 year old with three previous ME presents for contraceptive advice, she has a sister and a mom with breast cancer and she refuses to take the pills, can she use them?
Slide 20-

Prescription of Oral Contraceptives Counseling Begin COC or POP at any time if reasonably certain is not pg If begun within 5 days of bleeding no extra protection If not within 5 days use back up for 7 days if on COC, and for 2 days if on POP Begin immediately post abortion Rapidly reversible, within 2-3 months conceptions are seen Medical history and physical examination Selection of a particular preparation User instructions Missed pill instructions No evidence that obese patients suffer decreased efficacy
Slide 21-

Establishing that a patient is protected by her contraception Mode of action for contraceptive protection Molecular: P suppresses LH, E suppresses FSH Cellular: E increases intracellular P receptors Reproductive Organs: Endometrial atrophy, hostile cervical mucus Reproductive Processes WHO in last report said that it is not reliably known how accurately ultrasound findings, hormonal measurements or evaluation of the cervical mucus predict the risk of pregnancy during most contraceptive use

Oral Contraceptives and the Risk of Breast Cancer Results of a large epidemiologic study suggest that oral contraceptives do not cause breast cancer Breast cancer risk in women who have not taken oral contraceptives for ≥10 years is the same as those who have never used them There is a slightly increased risk of diagnosis in current users of oral contraceptives and in those who stopped taking them ≤10 years ago Tumors are more likely to be localized in oral contraceptive users than in nonusers Collaborative Group on Hormonal Factors in Breast Cancer.

Intrauterine Contracetion IUD IUS IUC
Slide 64-

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?
Slide 65-

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.
Slide 66-

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.

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. Spotting for first 3-6 months of use. Low EP rate (0.2-0.6/1000) Rapid return to fertility.
Slide 69-

LNG IUS As with other progestin-only methods, persistent follicles can occur (in less than 8 % of women). They do not require treatment. Produces both cervical barrier and intrauterine barrier to fertilizaiton Pakarinen et al. Fertil Steril 1997;68:59
Slide 70-

Candidates for IUDs: ParaGard T380 Nulliparous or parous women No longer a requirement to be mutally monogamous, but do avoid if high risk for STD or PID. Appropriate for all stages of reproductive life whether young, pg spacing or finished with childbearing. Not for someone with post-pg or post-ab infection within the past three months Uterine or cervical cancer Cervical infection Allergies.

Slide 73-

IUD Counseling No risk of infertility after discontinuing IUC No increased risk of PID except in the first 20 days after insertion No difference in complications for parous or nulliparous women
Slide 74-

IUD Counseling, continued Cu IUD at any time in the cycle if it is reasonably sure she is not pg, no additional protection is necessary It is not known exactly how soon it becomes effective If she is less than 48 hours postpartum she can have a Cu-IUD, or 4 or more weeks post partum and amenorrhoeic she can have a either IUD inserted Immediately post first trimester abortion and post second trimester she can generally have the IUD inserted Cu-IUD can be inserted within 5 days of unprotected intercourse, not farther as the risk of serious pelvic infection and septic spontaneous abortion If the LNG-IUD has been inserted more than 7 days into the cycle use protection for 7 days
Slide 75-

Bleeding with IUD use Spotting or light bleeding is common during first 3-6 months for either IUD NSAIDs Amenorrhea with Mirena doesn’t require treatment Persistent problem work up for gynecologic causes Heavier than normal menses with the Cu-IUD NSAIDs Tranexamic acid (a hemostatic agent) Do NOT use Asprin Treat anemia If anemia persists remove the IUD

Barrier Methods
Slide 77-

Contraceptive Cases A 18 year old reports that she and her partner were mutually stimulating each other and suddenly decided to have intercourse, she didn’t want to fuss with her diaphragm so she inserted a vaginal film immediately before penetration, was she protected? A woman’s cervical cap was discolored so she’s been cleaning it with Listerine, is it ok? Your patient is worried about HIV she makes her partner use two condoms but he thinks this is unsafe, who’s right?
Slide 78-

Phases of the Cervical Mucus Method Calendar (or calculation) method Basal body temperature (BBT) method Cervical mucus method (the Billings method) Sympto-thermal method
Slide 79-

Barrier Methods Not as effective as hormonal methods Most require concomitant spermicide Efficacy is highly dependent on consistent and correct use Some require partner cooperation Vaginal insertion and removal may be unacceptable Increased risk of urinary tract infection when used with a spermicide Some require fitting by a clinician Most are less effective in parous women No hormonal side effects Some methods available without prescription Some reduce sexually transmitted infections
Slide 80-

Efficacy: In a 28-week multicenter, randomized, parallel group study of unadjusted typical use (with spermicide), the probability of pregnancy was 7.9% Advantages: Can be inserted hours before intercourse Does not require removal between acts of intercourse Cost: Approximately $30.00 Diaphragm Mauck C, et al.

Adiana Delivery: A catheter placed through the operating channel of a small hysteroscope delivers low-power bipolar electrosurgical energy to the tubal orifice. A pushrod then delivers a small porous matrix of material in the tubal lumen.Occlusion: Ingrowth of healthy, vascularized tissue occurs over approximately 3 months, to occlude the tubes. Retention of the matrix and tubal occlusion are documented by both transvaginal ultrasonography and hysterosalpingogram before patients may discontinue additional contraception.

Rachel Benson Gold discusses a particularly troubling aspect of state laws in “The Implications of Defining When a Woman is Pregnant,” which appears in the same issue of TGR. 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.
Slide 118-

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.
Slide 119-

“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.”

Medical AbortionAdvantages 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
Slide 123-

Medical AbortionDisadvantages 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
Slide 124-

Surgical AbortionAdvantages More effective Shorter time to completion Fewer visits Shorter bleeding duration Always has pathologic confirmation Can be performed in later gestation
Slide 125-

Surgical AbortionDisadvantages More serious risks involved Limited access Requires more equipment and investment Providers more vulnerable to risk

“Expected” Side Effects GI: Nausea, Vomiting, Diarrhea Mild temperature elevation (PD effect) Cramping Headache, dizziness Bleeding
Slide 134-

“Expected” Bleeding Bleeding-moderate to heavy Some clots-small to large Onset average 2-4 hours after misoprostol Heaviest bleeding may last 1-4 hours as pregnancy is expelled Contact us if 2 maxipads/hour for 2 hours: call (pads should be ‘dripping wet’)
Slide 135-

“Expected” Cramping Cramps are light to heavy Pain usually managed with ibuprofen 600-800 mg/4-6 hours Prescription for acetaminophen with codeine may be given on day 1 or day 3 Night cramping usually worse before expulsion

Diagnosis of Complete Abortion Any abortion without suction curettage must have a confirmatory examination before the patient’s treatment course is complete Ultrasound disappearance of the gestational sac this usually mandates a transvaginal ultrasound Negative pregnancy test (<50 mIU/ml in urine) 90% drop in b-HCG
Slide 139-

Management of Complications Pain: May assess on an Likart scale Temperature: returns to normal 3-4 hours after misoprostol Failure to bleed: Do not treat EP with this regimen Heavy or prolonged bleeding: stops 1-2 hrs after passing pregnancy Rest, heating pads, NSAID or non-ASA Plenty of non-alcoholic beverages Clinician should call back 30-60 minutes to assess the patient’s condition Completion may take up to 3-4 weeks Return visits are the only way to assure completion 80-85% will abort within two weeks with Mtx-Misoprostol and 95-97% within two weeks with RU486-Misoprostol
Slide 140-

Complication Rates Surgical abortion: 9/100,000 overall with mortality <1/100,000 Most surgical complications result from instrumentation in the uterus and from second trimester procedures Medical abortion: complications are more difficult to assess: bleeding is expected, it can be heavy, hemorrhage is a complication US Trial 1/859 Tx adverse event rate of 0.17% Specific AEs From Medical Abortions of first 80,000 5 EP, one of which was fatal 13 transfusions (one was EP case) 117 had curettages, nearly all were non-emergent 10 received antibiotics for presumed infection 6 had allergic reactions 50 women had ongoing pregnancies, of which all but two terminated surgically
