OBJECTIVE(S): To understand how contraception method use differed between women prescribed and not prescribed medications for opioid use disorder (MOUD) among commercially-insured and Medicaid insured women. STUDY DESIGN: IBM Watson Health MarketScan Commercial Claims and Encounters database and the Multi-State Medicaid database were used to calculate the (1) crude prevalence, and (2) adjusted odds ratios (adjusted for demographic characteristics) of using long-acting reversible or short-acting hormonal contraception methods or female sterilization compared with none of these methods (no method) in 2018 by MOUD status among women with OUD, aged 20 to 49 years, with continuous health insurance coverage through commercial insurance or Medicaid for ≥6 years. Claims data was used to define contraception use. Fisher exact test or χ(2) test with a P-value ≤ 0.0001, based on the Holm-Bonferroni method, and 95% confidence intervals were used to determine statistically significant differences for prevalence estimates and adjusted odds ratios, respectively. RESULTS: Only 41% of commercially-insured and Medicaid-insured women with OUD were prescribed MOUD. Medicaid-insured women with OUD prescribed MOUD had a significantly lower crude prevalence of using no method (71.1% vs 79.0%) and higher odds of using female sterilization (aOR, 1.33; 95% CI: 1.06–1.67 vs no method) than those not prescribed MOUD. Among commercially-insured women there were no differences in contraceptive use by MOUD status and 66% used no method. CONCLUSIONS: Among women with ≥ 6 years of continuous insurance coverage, contraceptive use differed by MOUD status and insurance. Prescribing MOUD for women with OUD can be improved to ensure quality care. IMPLICATIONS: : Only two in five women with OUD had evidence of being prescribed MOUD, and majority did not use prescription contraception or female sterilization. Our findings support opportunities to improve prescribing for MOUD and integrate contraception and MOUD services to improve clinical care among women with OUD.

Background The goal of risk-appropriate maternal care is for high-risk pregnant women to receive specialized obstetrical services in facilities equipped with capabilities and staffing to provide care or transfer to facilities with resources available to provide care. In the United States, geographic access to critical care obstetrics varies. It is unknown whether this variation in proximity to critical care obstetrics differs by race, ethnicity, and region. Objective We examined the geographic access, defined as residence within 50 miles of a facility capable of providing risk-appropriate critical care obstetrics services for women of reproductive age, by distribution of race and ethnicity. Study Design Descriptive spatial analysis was used to assess geographic distance to critical care obstetrics for women of reproductive age by race and ethnicity. Data were analyzed geographically: nationally, by the Department of Health and Human Services regions, and by all 50 states and the District of Columbia. Dot density analysis was used to visualize geographic distributions of women by residence and critical care obstetrics facilities across the United States. Proximity analysis defined the proportion of women living within an approximate 50-mile radius of facilities. Source data included the 2015 American Community Survey from the United States Census Bureau and the 2015 American Hospital Association Annual Survey. Results Geographic access to critical care obstetrics was the greatest for Asian and Pacific Islander women of reproductive age (95.8%), followed by black (93.5%), Hispanic (91.4%), and white women of reproductive age (89.1%). American Indian and Alaska Native women had more limited geographic access (66%) in all regions. Visualization of proximity to critical care obstetrics indicated that facilities were predominantly located in urban areas, which may limit access to women in frontier or rural areas of states including nationally recognized reservations where larger proportions of white women and American Indian and Alaska Native women reside, respectively. Conclusion Disparities in proximity to critical care obstetrics exist in rural and frontier areas of the United States, which affect white women and American Indian and Alaska Native women, primarily. Examining insurance coverage, interstate hospital referral networks, and transportation barriers may provide further insight into critical care obstetrics accessibility. Further exploring the role of other equity-based measures of access on disparities beyond geography is warranted.

Objective To compare the risk of preeclampsia among spontaneously conceived pregnancies to those after hyperestrogenic ovarian stimulation (hyperestrogenic OS) with and without assisted reproductive technology (ART), and stimulation with non-hyperestrogenic aromatase inhibitor stimulation (non-hyperestrogenic OS). Methods Live-born singleton deliveries among women 20-49 years were identified in the 2004-2012 Truven Health MarketScan Commercial Claims and Encounters Databases using ICD-9 and CPT codes. Maternal characteristics were compared using Chi squared and Fisher exact tests. We performed multilevel multivariable logistic regression, controlling for maternal age, parity, comorbid conditions, and region of delivery, and calculated adjusted odds ratios (aOR) and 95 % confidence intervals for mild and severe preeclampsia. Results 1,014,526 spontaneously conceived, 6881 hyperestrogenic OS with ART, 27,516 hyperestrogenic OS without ART, and 2117 non-hyperestrogenic OS pregnancies were identified. The adjusted odds of developing preeclampsia were increased for deliveries after hyperestrogenic OS with ART (mild preeclampsia aOR 1.42, 1.24-1.62; severe preeclampsia aOR 1.83, 1.59-2.11) and without ART (mild preeclampsia aOR 1.32, 1.24-1.42; severe preeclampsia aOR 1.53, 1.41-1.66). Adjusted odds of preeclampsia were similar between spontaneously conceived and non-hyperestrogenic OS pregnancies. Conclusions for Practice Risk of preeclampsia after ART may in part be related to supraphysiologic estrogen associated with hyperestrogenic OS.

BACKGROUND: There is limited information on the patterns and trends of contraceptive use among women living with HIV, compared with noninfected women in the United States. Further, little is known about whether antiretroviral therapy correlates with contraceptive use. Such information is needed to help identify potential gaps in care and to enhance unintended pregnancy prevention efforts. OBJECTIVE: We sought to compare contraceptive method use among HIV-infected and noninfected privately insured women in the United States, and to evaluate the association between antiretroviral therapy use and contraceptive method use. STUDY DESIGN: We used a large US nationwide health care claims database to identify girls and women ages 15–44 years with prescription drug coverage. We used diagnosis, procedure, and National Drug Codes to assess female sterilization and reversible prescription contraception use in 2008 and 2014 among women continuously enrolled in the database during 2003 through 2008 or 2009 through 2014, respectively. Women with no codes were classified as using no method; these may have included women using nonprescription methods, such as condoms. We calculated prevalence of contraceptive use by HIV infection status, and by use of antiretroviral therapy among those with HIV. We used multivariable polytomous logistic regression to calculate unadjusted and adjusted odds ratios and 95% confidence intervals for female sterilization, long-acting reversible contraception, and short-acting hormonal contraception compared to no method. RESULTS: While contraceptive use increased among HIV-infected and noninfected women from 2008 through 2014, in both years, a lower proportion of HIV-infected women used prescription contraceptive methods (2008: 17.5%; 2014: 28.9%, compared with noninfected women (2008: 28.8%; 2014: 39.8%, P < .001 for both). Controlling for demographics, chronic medical conditions, pregnancy history, and cohort year, HIV-infected women compared to HIV-noninfected women had lower odds of using long-acting reversible contraception (adjusted odds ratio, 0.67; 95% confidence interval, 0.52–0.86 compared to no method) or short-acting hormonal contraception method (adjusted odds ratio, 0.59; 95% confidence interval, 0.50–0.70 compared to no method). In 2014, HIV-infected women using antiretroviral therapy were significantly more likely to use no method (76.8% vs 64.1%), and significantly less likely to use short-acting hormonal contraception (11.0% vs 22.7%) compared to HIV-infected women not using antiretroviral therapy. Those receiving antiretroviral therapy had lower odds of using short-acting hormonal contraception compared to no method (adjusted odds ratio, 0.45; 95% confidence interval, 0.32–0.63). There was no significant difference in female sterilization by HIV status or antiretroviral therapy use. CONCLUSION: Despite the safety of reversible contraceptives for women with HIV, use of prescription contraception continues to be lower among privately insured HIV-infected women compared to noninfected women, particularly among those receiving antiretroviral therapy.

Objective To assess trends and outcomes of assisted hatching among assisted reproductive technology (ART) cycles. Design Retrospective cohort analysis using National ART Surveillance System (NASS) data. Setting U.S. fertility centers reporting to NASS. Patient(s) Fresh autologous noncanceled ART cycles conducted from 2000–2010. Intervention(s) None. Main Outcome Measure(s) Implantation, clinical pregnancy, live-birth, miscarriage, multiple gestation. Result(s) Assisted hatching use statistically significantly increased in absolute number (from 25,724 to 35,518 cycles), percentages of day-3 (from 50.7% to 56.3%) and day-5 transfers (from 15.9% to 22.8%), and percentage of transfers among women ≥38 years (from 17.8% to 21.8%) or women with ≥2 prior ART cycles and no live birth(s) (from 4.3% to 7.4%). Both day-3 and day-5 cycles involving assisted hatching were associated with lower odds of implantation (adjusted odds ratios [aOR] 0.7 and 0.6, respectively), clinical pregnancy (aOR 0.8 and 0.7, respectively), live birth (aOR 0.8 and 0.7, respectively), and increased odds of miscarriage (aOR 1.4 and 1.4, respectively), as compared with cycles without assisted hatching. Assisted hatching was associated with lower odds of multiple gestation in day-5 cycles (aOR 0.8). In cycles for women with a "poor prognosis," the association of assisted hatching with pregnancy outcomes was not statistically significant. Conclusion(s) Assisted hatching use had an increasing trend but was not associated with improved pregnancy outcomes, even in poor-prognosis patients. Prospective studies are needed to identify the patients who may benefit from assisted hatching.

OBJECTIVE: To calculate incidence of postpartum venous thromboembolism by week after delivery and to examine potential risk factors for venous thromboembolism overall and at different times during the postpartum period. METHODS: A deidentified health care claims information database from employers, health plans, hospitals, and Medicaid programs across the United States was used to identify delivery hospitalizations among women aged 15–44 years during the years 2005–2011. International Classification of Diseases, 9th Revision, Clinical Modification diagnosis and procedure codes were used to identify instances of venous thromboembolism and associated characteristics and conditions among women with recent delivery. Incidence proportions of venous thromboembolism by week postpartum through week 12 were calculated per 10,000 deliveries. Logistic regression was used to calculate odds ratios for selected risk factors among women with postpartum venous thromboembolism and among women with venous thromboembolism during the early or later postpartum periods. RESULTS: The incidence proportion of postpartum venous thromboembolism was highest during the first 3 weeks after delivery, dropping from nine per 10,000 during the first week to one per 10,000 at 4 weeks after delivery and decreasing steadily through the 12th week. Certain obstetric procedures and complications such as cesarean delivery, preeclampsia, hemorrhage, and postpartum infection conferred an increased risk for venous thromboembolism (odds ratios ranging from 1.3 to 6.4), which persisted over the 12-week period compared with women without these risk factors. CONCLUSION: Risk for postpartum venous thromboembolism is highest during the first 3 weeks after delivery. Women with obstetric complications are at highest risk for postpartum venous thromboembolism, and this risk remains elevated throughout the first 12 weeks after delivery.

To examine trends in severe maternal morbidity from 2008 to 2012 in delivery and postpartum hospitalizations among pregnancies conceived with or without assisted reproductive technology (ART).In this retrospective cohort study, deliveries were identified in the 2008-2012 Truven Health MarketScan Commercial Claims and Encounters Databases. Severe maternal morbidity was identified using International Classification of Diseases, 9th Revision, Clinical Modification diagnosis codes and Current Procedural Terminology codes. Rate of severe maternal morbidity was calculated for ART and non-ART pregnancies. We performed multivariable logistic regression, controlling for maternal characteristics, and calculated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for severe morbidity. Additionally, a propensity score analysis was performed between ART and non-ART deliveries.Of 1,016,618 deliveries, 14,761 (1.5%) were identified as pregnancies conceived with ART. Blood transfusion was the most common severe morbidity indicator for ART and non-ART pregnancies. For every 10,000 singleton deliveries, there were 273 ART deliveries or postpartum hospitalizations with severe maternal morbidity compared with 126 for non-ART (P.001). For ART singleton deliveries, the rate of severe morbidity decreased from 369 per 10,000 deliveries in 2008 to 219 per 10,000 deliveries in 2012 (P=.025). Odds of severe morbidity were increased for ART compared with non-ART singletons (adjusted OR 1.84, 95% CI 1.63-2.08). Among multiple gestations, there was no significant difference between ART and non-ART pregnancies (rate of severe morbidity for ART 604/10,000 and non-ART 539/10,000 deliveries, P=.089; adjusted OR 1.04, 95% CI 0.91-1.20). Propensity score matching agreed with these results.Singleton pregnancies conceived with ART are at increased risk for severe maternal morbidity; however, the rate has been decreasing since 2008. Multiple gestations have increased risk regardless of ART status.

Background Migraine with aura and combined hormonal contraceptives are independently associated with an increased risk of ischemic stroke. However, little is known about whether there are any joint effects of migraine and hormonal contraceptives on risk of stroke. Objective We sought to estimate the incidence of stroke in women of reproductive age and examine the association among combined hormonal contraceptive use, migraine type (with or without aura), and ischemic stroke. Study Design This study used a nationwide health care claims database and employed a nested case-control study design. Females ages 15-49 years with first-ever stroke during 2006 through 2012 were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification inpatient services diagnosis codes. Four controls were matched to each case based on age. Migraine headache with and without aura was identified using inpatient or outpatient diagnosis codes. Current combined hormonal contraceptive use was identified using the National Drug Code from the pharmacy database. Conditional logistic regression was used to estimate adjusted odds ratios and 95% confidence intervals of ischemic stroke by migraine type and combined hormonal contraceptive use. Results From 2006 through 2012, there were 25,887 ischemic strokes among females ages 15-49 years, for a cumulative incidence of 11 strokes/100,000 females. Compared to those with neither migraine nor combined hormonal contraceptive use, the odds ratio of ischemic stroke was highest among those with migraine with aura using combined hormonal contraceptives (odds ratio, 6.1; 95% confidence interval, 3.1–12.1); odds ratios were also elevated for migraine with aura without combined hormonal contraceptive use (odds ratio, 2.7; 95% confidence interval, 1.9–3.7), migraine without aura and combined hormonal contraceptive use (odds ratio, 1.8; 95% confidence interval, 1.1–2.9), and migraine without aura without combined hormonal contraceptive use (odds ratio, 2.2; 95% confidence interval, 1.9–2.7). Conclusion The joint effect of combined hormonal contraceptives and migraine with aura was associated with a 6-fold increased risk of ischemic stroke compared with neither risk factor. Use of combined hormonal contraceptives did not substantially further increase risk of ischemic stroke among women with migraine without aura. Determining migraine type is critical in assessing safety of combined hormonal contraceptives among women with migraine.
