OBJECTIVE To determine pharmacy availability of ulipristal acetate (UPA) and compare to availability of levonorgestrel-containing emergency contraceptive pills (LNG-ECPs). METHODS We conducted an observational population-based study utilizing a telephone-based secret shopper methodology. Researchers called all 198 unique retail pharmacies in Hawaii on December 2013-June 2014, representing themselves as patients and physicians. RESULTS Only 2.6% of pharmacies had UPA immediately available, though 22.8% reported ability to order UPA. In contrast, 82.4% reported immediate availability of LNG-ECPs. No significant difference in availability was reported to patients and physicians. CONCLUSIONS Availability of UPA is limited and significantly lower compared to LNG-ECPs. The study period did overlap with a change in distributor for UPA, likely capturing some disruption of the supply chain. IMPLICATIONS Systems-based interventions are needed to address barriers to obtaining UPA.

Contraceptive Coverage and the Affordable Care Act

Mary Tschann; Reni Soon

A major goal of the Patient Protection and Affordable Care Act is reducing healthcare spending by shifting the focus of healthcare toward preventive care. Preventive services, including all FDA-approved contraception, must be provided to patients without cost-sharing under the ACA. No-cost contraception has been shown to increase uptake of highly effective birth control methods and reduce unintended pregnancy and abortion; however, some institutions and corporations argue that providing contraceptive coverage infringes on their religious beliefs. The contraceptive coverage mandate is evolving due to legal challenges, but it has already demonstrated success in reducing costs and improving access to contraception.

Interpregnancy interval and subsequent pregnancy outcomes after dilation and evacuation

Abstract We conducted this study to compare outcomes for pregnancies conceived ≤6 months after dilation and evacuation (D&E) with those conceived >6 months after D&E. This retrospective cohort study included women who underwent D&E (14–26 weeks) and were readmitted with a subsequent pregnancy. The primary outcome was the rate of preterm birth (<37 weeks). We identified 737 D&Es with 214 subsequent pregnancies. Outcomes were available for 85.5% of these pregnancies. Preterm birth <37 weeks occurred in 9.4% (3/32) of patients with an interpregnancy interval ≤6 months and 20.7% (12/58) of patients with an interpregnancy interval >6 months (p = .17). No differences in preterm birth <34 weeks, postpartum haemorrhage, placentation abnormalities, intrauterine growth restriction, cervical insufficiency or mode of delivery were noted. Adverse pregnancy outcomes were not higher in the group of women who conceived ≤6 months after D&E compared to those who waited longer than 6 months. IMPACT STATEMENT What is already known on this subject: A small number of studies have noted an increased risk of adverse pregnancy outcomes with an interpregnancy interval of 6 months or fewer after a spontaneous or an induced abortion. What the results of this study add: We present the first study exploring pregnancy outcomes after dilation and evacuation for termination of pregnancy at 14 weeks or greater. Our results do not support an increased rate of adverse events with an interpregnancy interval of 6 months or fewer following dilation and evacuation. What the implications are of these findings for clinical practice and/or further research: Because of limitations in sample size, our results should be interpreted in the context of other studies.

OBJECTIVE Our objective was to document current practices of abortion providers on the use of medications to decrease bleeding during surgical abortion. STUDY DESIGN We emailed surveys to 336 abortion providers through a professional listserv to elicit information on their use of medications to prevent and treat bleeding during first- and second-trimester surgical abortion. RESULTS One hundred sixty-eight (50%) providers responded to our survey. The majority were obstetrician-gynecologists (83%) working in an academic practice (66%). Most completed a fellowship in family planning (87%) and currently perform abortions up to 22 or 24weeks of gestation (63%). Seventy-two percent routinely used prophylactic medications for bleeding. Providers who routinely used medications to prevent bleeding most commonly chose vasopressin (83%). Providers preferred methylergonovine as a treatment for excessive bleeding in the second trimester, followed by misoprostol. CONCLUSION We found that most providers routinely use medications to prevent bleeding and use several different regimens to treat bleeding during abortion. IMPLICATIONS We found that surgical abortion providers use a range of medications to prevent and treat hemorrhage at the time of surgical abortion. Scant evidence is available to guide abortion providers on the use of medications to decrease hemorrhage during surgical abortion. To provide evidence-based recommendations for the prevention and treatment of clinically significant bleeding, researchers should target the most commonly used interventions.

Blood loss at the time of dilation and evacuation at 16 to 22 weeks of gestation in women using low molecular weight heparin: a case series

OBJECTIVE Describe blood loss with surgical abortion ≥16weeks of gestation in anticoagulated patients. STUDY DESIGN Clinicians involved in a professional listserv (2011-2013) reported cases of abortion ≥16weeks of gestation in anticoagulated women. RESULTS All 7 patients were using or had recently discontinued low molecular weight heparin (LMWH). One patient was reported to have greater than anticipated blood loss for gestational age. No patients required transfusion and no complications were reported. CONCLUSIONS Our limited case series suggests D&E may not always be contraindicated in women with recent or current LMWH use.

Pharmacy Access to Ulipristal Acetate in Major Cities throughout the United States

OBJECTIVE Ulipristal acetate (UPA) is a prescription emergency contraceptive pill (ECP). Despite the potential for UPA to reduce the risk of unintended pregnancies, a recent study in Hawaii demonstrated less than 3% of pharmacies stocked UPA and less than 23% reported the ability to order it. The primary outcome of our study was to assess the availability of UPA in a sample of large cities nationwide. STUDY DESIGN We conducted a telephone-based secret shopper study of 533 retail pharmacies sampled proportionally from 10 large cities in five geographic regions across the US. Callers represented themselves as uninsured 18-year-old women attempting to fill prescriptions for UPA between February and May 2016. Using a semi-structured questionnaire, callers inquired regarding availability and use of UPA. RESULTS Less than 10% (33/344; 95% CI: 6.5-12.7%) of pharmacies indicated the ability to immediately fill a UPA prescription, while 72% (224/311; 95% CI: 65.0-77.0%) of pharmacies without immediate availability reported the ability to order UPA, with the median predicted wait time of 24 h (IQR: 21.5 to 26.0 h). CONCLUSION Despite evidence for increased efficacy of UPA over levonorgestrel (LNG) ECPs, the availability of UPA in a sample of US major cities is extremely limited. Given that ECPs should be taken as soon as possible after unprotected sex, the long wait times when ordering UPA present an access barrier. Efforts to improve the availability of UPA are important to optimize the potential of ECPs to decrease unintended pregnancy following unprotected sex. IMPLICATIONS Interventions are needed to address barriers to obtaining UPA from retail pharmacies nationwide.
