OBJECTIVE: To estimate whether 6-month use of the levonorgestrel-releasing intrauterine device (IUD) would be higher when insertion occurred within 10 minutes of placental delivery compared with 6–8 weeks postpartum. METHODS: We enrolled pregnant women planning vaginal deliveries and desiring a postpartum levonorgestrel-releasing IUD. Patients were randomly assigned when admitted in labor to postplacental or delayed IUD insertion. The women followed up in person at 6–8 weeks and 6 months and were contacted by telephone at 3 months. Women were ineligible for a study IUD postenrollment for intrapartum events including infection, hemorrhage, and cesarean delivery; these women were contacted by phone at 3 and 6 months. Expelled IUDs were replaced per patient preference. RESULTS: Successful IUD placement occurred in 50 of 51 participants (98.0%) and 46 of 51 participants (90.2%) in the postplacental and delayed groups, respectively (P=.2). Expulsion within 6 months occurred in 12 of 50 (24.0%; 95% confidence interval [CI], 13.1–38.2) and two of 46 (4.4%; 95% CI 0.5–14.8) participants, respectively (P=.008). Intrauterine device use at 6 months was 43 of 51 (84.3%; 95% CI 71.4–93.0) and 39 of 51 (76.5%; 95% CI 62.5–87.2), respectively (P=.32). For ineligible patients, only 11 of 41 (26.8%) women were using IUDs at 6 months and two (4.9%) had become pregnant. CONCLUSION: Intrauterine device use 6 months after delivery is similar in women who have postpartum or scheduled delayed IUD placement through a study after replacement of expelled IUDs. Expulsions are significantly higher with postplacental compared with delayed IUD placement. Women asked to follow up with their own health care providers for delayed insertion are significantly less likely to receive an IUD.

BACKGROUND This study was conducted to assess the feasibility of using telephone calls combined with high-sensitivity urine pregnancy testing as a primary method of follow-up after medical abortion. METHODS We enrolled 139 women up to 63 days of gestation to receive mifepristone 200 mg orally and misoprostol 800 mcg vaginally or buccally, per their choice. Participants were contacted by phone one week after mifepristone administration and interviewed using standardized questions. If the subject or clinician thought the pregnancy was not expelled, the subject returned for an ultrasound examination. Otherwise, subjects performed high-sensitivity home urine pregnancy testing 30 days after the mifepristone and were called within 3 days of the test. Those with positive pregnancy tests returned for an ultrasound examination. Those with negative tests required no further follow-up. RESULTS Six of the 139 (4.3%, 95% CI 1.6-9.1%) subjects presented prior to Phone Call 1 for an in-person visit. All 133 (100%, 95% CI 97.8-100%) subjects eligible for their first telephone follow-up were contacted. Eight of the 133 (6.1%, 95% CI 2.6-11.5%) women were asked to return for evaluation and all did so (100%, 95% CI 63.1-100%). Eight of the 133 women eligible for the 30 day phone call presented for an interim visit prior to the call. After 30 days, 116 of the 117 (99.1%, 95% CI 97.5-100%) eligible subjects were contacted. One subject was not reached for the day 30 phone call. Twenty-seven of the 116 (23.3%, 95% CI 15.6-31.0%) subjects had a positive pregnancy test and required follow-up. Two of these subjects (7.4%, 95% CI 1.0-24.2%) did not return for in-person follow-up. Two of the 116 (1.7%, 95% CI 0.2-6.1%) subjects had inconclusive pregnancy tests and were asked to return for follow-up. One of these subjects (50%, 95% CI 1.2-98.7%) did not return. Complete follow-up was achieved in 135 of the 139 subjects (97.1%, 95% CI 94.3-99.9%). None of the 26 women evaluated for a positive or inconclusive pregnancy test had a gestational sac or continuing pregnancy. CONCLUSION Telephone follow-up combined with urine pregnancy testing after medical abortion is a feasible alternative to routine ultrasonography or serial serum hCG measurements.

Prior uterine evacuation of pregnancy as independent risk factor for preterm birth: a systematic review and metaanalysis

Gabriele Saccone; Lisa K. Perriera; Vincenzo Berghella

BACKGROUND Preterm birth (PTB) is the number one cause of perinatal mortality. Prior surgery on the cervix is associated with an increased risk of PTB. History of uterine evacuation, by either induced termination of pregnancy (I-TOP) or spontaneous abortion (SAB), which involve mechanical and/or osmotic dilatation of the cervix, has been associated with an increased risk of PTB in some studies but not in others. OBJECTIVE The objective of the study was to evaluate the risk of PTB among women with a history of uterine evacuation for I-TOP or SAB. DATA SOURCES Electronic databases (MEDLINE, Scopus, ClinicalTrials.gov, EMBASE, and Sciencedirect) were searched from their inception until January 2015 with no limit for language. STUDY ELIGIBILITY CRITERIA We included all studies of women with prior uterine evacuation for either I-TOP or SAB, compared with a control group without a history of uterine evacuation, which reported data about the subsequent pregnancy. STUDY APPRAISAL AND SYNTHESIS METHODS The primary outcome was the incidence of PTB < 37 weeks. Secondary outcomes were incidence of low birthweight (LBW) and small for gestational age (SGA). We planned to assess the primary and the secondary outcomes in the overall population as well as in studies on I-TOP and SAB separately. The pooled results were reported as odds ratio (OR) with 95% confidence interval (CI). RESULTS We included 36 studies in this metaanalysis (1,047,683 women). Thirty-one studies reported data about prior uterine evacuation for I-TOP, whereas 5 studies reported data for SAB. In the overall population, women with a history of uterine evacuation for either I-TOP or SAB had a significantly higher risk of PTB (5.7% vs 5.0%; OR, 1.44, 95% CI, 1.09-1.90), LBW (7.3% vs 5.9%; OR, 1.41, 95% CI, 1.22-1.62), and SGA (10.2% vs 9.0%; OR, 1.19, 95% CI, 1.01-1.42) compared with controls. Of the 31 studies on I-TOP, 28 included 913,297 women with a history of surgical I-TOP, whereas 3 included 10,253 women with a prior medical I-TOP. Women with a prior surgical I-TOP had a significantly higher risk of PTB (5.4% vs 4.4%; OR, 1.52, 95% CI, 1.08-2.16), LBW (7.3% vs 5.9%; OR, 1.41, 95% CI, 1.22-1.62), and SGA (10.2% vs 9.0%; OR, 1.19, 95% CI, 1.01-1.42) compared with controls. Women with a prior medical I-TOP had a similar risk of PTB compared with those who did not have a history of I-TOP (28.2% vs 29.5%; OR, 1.50, 95% CI, 1.00-2.25). Five studies, including 124,133 women, reported data about a subsequent pregnancy in women with a prior SAB. In all of the included studies, the SAB was surgically managed. Women with a prior surgical SAB had a higher risk of PTB compared with those who did not have a history of SAB (9.4% vs 8.6%; OR, 1.19, 95% CI, 1.03-1.37). CONCLUSION Prior surgical uterine evacuation for either I-TOP or SAB is an independent risk factor for PTB. These data warrant caution in the use of surgical uterine evacuation and should encourage safer surgical techniques as well as medical methods.

Immediate versus delayed insertion of the levonorgestrel-releasing intrauterine device following dilation and evacuation: a randomized controlled trial

Heather L. Hohmann; Matthew F. Reeves; Beatrice A. Chen; Lisa K. Perriera; Jennifer L. Hayes; Mitchell D. Creinin

BACKGROUND The study was conducted to compare 6-month usage of the levonorgestrel-releasing intrauterine device (LNG-IUD) when placed immediately or 3 to 6 weeks after dilation and evacuation (D&E) procedure. STUDY DESIGN We enrolled women undergoing D&E at 15 to 23 weeks of gestation. After completion of the D&E, subjects without contraindications to immediate IUD insertion were randomized to immediate or delayed (3 to 6 weeks later) LNG-IUD insertion. Subjects in the immediate group had the LNG-IUD placed using ultrasound guidance. All subjects returned at 3 to 6 weeks and 8 to 10 weeks after D&E and were contacted by phone at 6 months. RESULTS Of the 93 subjects enrolled, 88 were randomized. All 44 subjects (100%) randomized to immediate insertion had successful IUD placement, while only 20 (45.5%) of the 44 subjects randomized to delayed insertion returned for IUD placement, all of which were successful [difference 54.5%, 95% confidence interval (CI) 39.8%-69.3%]. Seventeen (38.6%) participants in each group were lost to follow-up. Of subjects contacted at the 6-month follow-up phone call, 23 of 27 women (85.2%) and 17 of 27 women (62.9%) were utilizing the LNG-IUD in the immediate and delayed groups, respectively (difference 22.2%, 95% CI -0.4% to 44.8%). Intrauterine device expulsion occurred in three subjects (6.8%) and one subject (5.0%) in whom the IUD was placed in the immediate and delayed groups, respectively (p=1.0). No significant adverse events occurred. CONCLUSION Significantly more participants had the LNG-IUD placed in the immediate insertion group compared with the delayed insertion group. Given the low risk of complications, immediate post-D&E insertion of the LNG-IUD should be offered, especially for populations that may have difficulty returning for follow-up.

Ultrasound Criteria for Diagnosis of Early Pregnancy Failure and Ectopic Pregnancy

Lisa K. Perriera; Matthew F. Reeves

Early pregnancy failure and ectopic pregnancy are common clinical diagnoses for which ultrasound can provide useful information. This review explores the use of ultrasound to diagnose early pregnancy failure and ectopic pregnancy. By documenting the developmental milestones of early normal pregnancy using ultrasound, clinicians can distinguish normal from abnormal intrauterine pregnancies. An early pregnancy failure can be diagnosed by the absence of a visible yolk sac with a mean sac diameter of 13 mm; the absence of a visible embryo with a mean sac diameter of 20 [corrected] mm; the absence of cardiac motion with an embryo measuring 5 mm or more in maximal length; or the presence of an empty amnion. In most settings, documentation of a normal intrauterine pregnancy effectively eliminates the possibility of ectopic pregnancy. The presence of an adnexal mass in the absence of an intrauterine gestational sac may indicate an ectopic pregnancy.

BACKGROUND:The primary objective of this study was to assess the risk of perioperative anesthesia-related complications in a cohort of obese and non-obese women undergoing outpatient surgical abortion under IV sedation without tracheal intubation. METHODS:We performed a retrospective cohort study of all surgical abortions through 22 6/7 weeks’ gestation at an outpatient clinic from 2012 to 2013. Women receiving IV sedation were included. Obesity status was defined by the World Health Organization criteria. The primary outcome was the rate of perioperative anesthesia complications defined as tracheal intubation, pulmonary aspiration, hospital transfer for an anesthesia indication, or anesthesia-related adverse events (persistent hypoxemia and allergic reaction). The use of opioid reversal (naloxone) was assessed as a secondary outcome measure. Multivariate analysis for the secondary outcome measure was performed with adjustment for confounding factors. RESULTS:During the study period, 9348 abortions were performed. Of the 5579 patients who received IV sedation, 1438 (25.8%) were obese, 1707 (30.6%) were in the second trimester, and 851 (15.3%) were ≥17 weeks’ gestation. No patients experienced a primary outcome measure. Based on the upper 95% confidence interval (CI) for the sample size, the maximal risk of an anesthesia-related complication is 1 in 1860 procedures. Naloxone use occurred in 13 (0.2%) patients and was not more frequent among obese patients (0.14% vs 0.27%; 95% CI of odds ratio [OR], 0.12–2.36; P = 0.54) or procedures at ≥17 weeks’ gestation (0.47% vs 0.19%; 95% CI of OR, 0.76–8.06; P = 0.12). These negative findings should be interpreted with caution, given the limitations of the sample size to assess these secondary outcome measures. Naloxone use was associated with fentanyl doses >200 &mgr;g (0.82% vs 0.13%; P = 0.002), an association that remained significant when we controlled for confounding factors (adjusted OR, 5.51; 95% CI, 1.61–18.91). Further analysis revealed that fentanyl dose >200 &mgr;g was associated with naloxone use for procedures in the first trimester (incident rate ratio, 9.02; 95% CI, 3.73–21.80) but not in the second trimester (incident rate ratio, 0.92; 95% CI, 0.23–3.70). CONCLUSIONS:Among women receiving IV sedation without tracheal intubation for surgical abortion, anesthesia complications are rare and may not be greater for obese women or procedures at gestational age ≥17 weeks. IV sedation without tracheal intubation may be considered for women undergoing first- and second-trimester surgical abortion; however, the rarity of anesthesia-related complications in our cohort precludes a definitive conclusion regarding the overall safety of IV sedation without tracheal intubation.

OBJECTIVES To evaluate whether home visits for contraceptive implant insertion result in an increase in postpartum uptake compared to clinic insertion and to assess the feasibility of home insertions. STUDY DESIGN We randomized women within 10 weeks of a birth or dilation and curettage (D&C) for abortion or miscarriage to home or standard office insertion. The primary outcome was successful insertion of the implant. To achieve 80% power to detect a 40% difference in visit attendance, 20 women were assigned to each group. The secondary outcome was attendance of the 4-week postpartum visit. RESULTS From June 2013 through February 2014, we screened 45 women and 40 were randomly assigned to home and office insertion visits. We enrolled 37 postpartum women and 3 women post-D&C. Because of the significant under enrollment of the latter, we chose to report results of only the postpartum women. The results were similar whether we included or excluded post-abortion women. A majority of women desired a home visit for their implant insertion appointment at time of enrollment. Postpartum appointment attendance rates were similar between home and office visits at 53% and 50% (p=1.00), respectively. Home visits resulted in a trend toward increased implant uptake [12/19 (63%) vs 6/18 (33%), p=.10]. CONCLUSION Home insertion of the contraceptive implant may be a feasible option. Future studies that examine the feasibility and uptake in both postpartum and post-D&C women are warranted. IMPLICATIONS Women reported preference for home insertion visits in this pilot study. We also showed that a greater proportion of women received the etonogestrel implant at a home visit compared to the current standard of care, which may warrant larger studies that would have sufficient power to evaluate smaller differences.

Hormonal contraception as treatment for heavy menstrual bleeding: a systematic review.

Suji Uhm; Lisa K. Perriera

A systematic review to compare the effectiveness of contraceptives to treat heavy menstrual bleeding (HMB). PubMed was searched for studies using hormonal contraceptive methods to treat HMB. Two reviewers screened 734 citations and extracted eligible trials based on rigid inclusion and exclusion criteria. Fourteen articles met inclusion criteria. The evidence was good to poor quality and suggested that all contraceptives tested were effective in the treatment of HMB, but the levonorgestrel intrauterine system was the most effective method. Hormonal contraceptives effectively treat HMB. The levonorgestel intrauterine system is the superior method.
