ABSTRACT

OBJECTIVES: To evaluate the availability of mifepristone and misoprostol at pharmacies in a state with protective abortion legislation and variation in access by rurality. STUDY DESIGN: Using a secret shopper survey, researchers attempted to contact all community pharmacies in Oregon and evaluate their mifepristone and misoprostol provisions. RESULTS: Among the 444 pharmacies surveyed, mifepristone was planned at 19.2%. Misoprostol was available at 77.5%, but stocking issues and medication ordering impact access, without significant differences by rurality. CONCLUSIONS: Pharmacy engagement and support are key to increasing access to these essential medicines, which may be improved through education and referral programs.

ABSTRACT

OBJECTIVE: To assess the cost effectiveness of targeting a blood pressure of less than 140/90 mm Hg compared with 160/105 mm Hg. METHODS: A decision-analytic model was constructed to compare the treatment of chronic hypertension in pregnancy at mild-range blood pressures (140/90 mm Hg) with the treatment of chronic hypertension before 20 weeks of gestation at severe-range blood pressures (160/105 mm Hg) in a theoretical cohort of 180,000 patients with mild chronic hypertension. Probabilities, costs, and utilities were derived from literature and varied in sensitivity analyses. Primary outcomes included incremental cost per quality-adjusted life-year (QALY), cases of preeclampsia, preeclampsia with severe features, severe maternal morbidity (SMM), preterm birth, maternal death, neonatal death, and neurodevelopmental delay. The cost-effectiveness threshold was $100,000 per QALY. RESULTS: Treating chronic hypertension in a population of 180,000 pregnant persons at mild-range blood pressures, compared with severe-range blood pressures, resulted in 14,177 fewer cases of preeclampsia (43,953 vs 58,130), 11,835 of which were cases of preeclampsia with severe features (40,530 vs 52,365). This led to 817 fewer cases of SMM (4,375 vs 5,192), and 18 fewer cases of maternal death (102 vs 120). Treating at a lower threshold also resulted in 8,078 fewer cases of preterm birth (22,000 vs 30,078), which led to 26 fewer neonatal deaths (276 vs 302) and 157 fewer cases of neurodevelopmental delay (661 vs 818). Overall, treating chronic hypertension at a lower threshold was a dominant strategy that resulted in decreased costs of $600 million and increased effectiveness of 12,852 QALYs. CONCLUSION: Treating chronic hypertension at a threshold of mild-range blood pressures is a dominant (lower costs, better outcomes) and cost-effective strategy that results in fewer neonatal and maternal deaths compared with the standard treatment of treating at severe range blood pressures.

ABSTRACT

OBJECTIVE: Despite a downward trend in recent years, adolescent pregnancies in the United States remain higher than any other western country. Adolescent pregnancies have been inconsistently associated with adverse perinatal outcomes. The objective of this study is to investigate the association between adolescent pregnancies and adverse perinatal and neonatal outcomes in the United States. STUDY DESIGN: This is a retrospective cohort study of singleton births in the United States from 2014 to 2020 using national vital statistics data. Perinatal outcomes included gestational diabetes, gestational hypertension, preterm delivery <37 weeks (preterm birth [PTB]), cesarean delivery (CD), chorioamnionitis, small for gestational age (SGA), large for gestational age (LGA), and neonatal composite outcome. Chi-square tests were used to compare outcomes among adolescent (13-19 years) versus adult (20-29 years) pregnancies. Multivariable logistic regression models were used to examine association of adolescent pregnancies with perinatal outcomes. For each outcome, we utilized three models: unadjusted logistic regression, adjusted for demographics, and adjusted for demographics and medical comorbidities. Similar analyses were used to compare younger (13-17 years) and older (18-19 years) adolescent pregnancies to adults. RESULTS: In a cohort of 14,014,078 pregnancies, we found that adolescents were at an increased risk of PTB (adjusted odds ratio [aOR]: 1.12, 99% confidence interval (CI): 1.12-1.13) and SGA (aOR: 1.02, 99% CI: 1.01-1.03) compared with adult pregnancies. We also found that multiparous adolescents with a prior history of CD were at an increased risk of CD, compared with adults. For all other outcomes, adult pregnancies were at higher risk for adverse outcomes in the adjusted models. When comparing birth outcomes among adolescents, we found that older adolescents are at an increased risk of PTB, whereas younger adolescents are at an increased risk of both PTB and SGA. CONCLUSION: After adjusting for confounders, our study demonstrates adolescents have an increased risk of PTB and SGA, compared with adults. KEY POINTS: · Adolescents as a whole subgroup have an increased risk of PTB and SGA compared with adults.. · Younger adolescents have a risk of PTB and SGA, whereas older adolescents have a risk of PTB only.. · Adverse birth outcomes in adults are gestational diabetes, chorioamnionitis, LGA, and worse neonatal composite score..

ABSTRACT

BACKGROUND: Eviction during pregnancy has been shown to be associated with adverse birth outcomes. A safety net program focused on covering the costs of rent during pregnancy may aid in preventing adverse complications. OBJECTIVE: This study aimed to evaluate the cost-effectiveness of a program covering the cost of rent to prevent eviction during pregnancy. STUDY DESIGN: A cost-effectiveness model using TreeAge software was designed to evaluate the cost, effectiveness, and incremental cost-effectiveness ratio associated with eviction compared to no eviction during pregnancy. The cost of eviction from a societal perspective was compared to the annual cost of housing in the no eviction group, which was estimated by the median contract rent in the United States from 2021 national census data. Birth outcomes included preterm birth, neonatal death, and major neurodevelopmental delay. Probabilities and costs were derived from the literature. The cost-effectiveness threshold was set at $100,000/QALY. We performed univariable and multivariable sensitivity analyses to assess the robustness of the results. RESULTS: In our theoretical cohort of 30,000 pregnant individuals aged 15 to 44 years facing eviction annually, the no eviction during pregnancy strategy was associated with 1427 fewer preterm births, 47 fewer neonatal deaths, and 44 fewer cases of neurodevelopmental delay compared to eviction. At the median cost of rent in the United States, the no eviction strategy was associated with increased quality-adjusted life-years and decreased costs. Therefore, the no eviction strategy was the dominant strategy. In univariate sensitivity analysis varying the cost of housing, no eviction remained the cost-effective strategy and was cost-saving when rent was below $1016 per month. CONCLUSION: The no eviction strategy is cost-effective and reduces cases of preterm birth, neonatal death, and neurodevelopmental delay. When rent is below the median of $1016 per month, no eviction is the cost-saving strategy. These findings suggest that policies supporting social programmatic implementation for rent coverage for pregnant people at risk of eviction have the potential to be highly beneficial in reducing costs and disparities in perinatal outcomes.

ABSTRACT

Importance: Many states enacted 20-week abortion bans from 2011 to 2018. Such bans affect individuals who receive diagnoses of fetal anomalies and aneuploidy in the second trimester, preventing pregnant individuals from having the choice of whether or not to continue the pregnancy. Objectives: To examine the trends of neonatal Down syndrome rates and assess the association between enactment of 20-week abortion bans and rates of Down syndrome diagnosis. Design, Setting, and Participants: This population-based, historical cohort study used National Vital Statistics System data on 31 157 506 births in the US from 2011 to 2018. Statistical analysis was performed from May 2021 to February 2023. Exposure: States were categorized as those with or without a 20-week abortion ban enacted during the study period. Main Outcomes and Measures: Demographic characteristics between the ban and no-ban states were compared using χ2 tests and 2-sample t tests. Multivariable logistic regression evaluated the adjusted odds of Down syndrome among births in states that enacted 20-week abortion bans after the abortion ban enactment, adjusting for state, year of birth, maternal race and ethnicity, age, educational level, insurance, and number of prenatal visits. Results: The cohort consisted of 31 157 506 births (mean [SD] maternal age, 28.4 [5.9] years) in the United States, of whom 15 951 neonates (0.05%) received a diagnosis of Down syndrome at birth. A total of 17 states enacted 20-week abortion bans during the study period, and 33 states did not enact bans. In both states with and states without bans, the birth prevalence of neonatal Down syndrome increased over time; in states with bans, rates increased from 48.0 to 58.4 per 100 000 births; in states without bans, rates increased from 47.4 to 53.3 per 100 000 births. In multivariable logistic regression assessing the interaction of time and presence of a 20-week abortion ban, the odds of Down syndrome were higher in states that enacted 20-week abortion bans after enactment of the law compared with the years prior to enactment of the ban (adjusted odds ratio, 1.22; 95% CI, 1.11-1.35). Conclusions and Relevance: In the US from 2011 to 2018, neonatal Down syndrome diagnoses increased more in states that enacted 20-week abortion bans compared with states that did not enact bans. Because these abortion bans were enacted throughout the study period and are known to inhibit choice in patient decision-making, it is possible that the difference in the rates of diagnosis is associated with these policies.

ABSTRACT

OBJECTIVE: To assess the cost effectiveness of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccination in pregnant patients in the United States. METHODS: A decision-analytic model in TreeAge was developed to compare universal Tdap vaccination in pregnancy with no Tdap vaccination in pregnancy using a theoretical cohort of 3.66 million pregnant individuals, the approximate number of deliveries per year in the United States. Outcomes included infant pertussis infections, infant hospitalizations, infant encephalopathy cases, infant deaths, and maternal pertussis infections. All probabilities and costs were derived from the literature. Utilities were applied to discounted life expectancies at a rate of 3% to generate quality-adjusted life-years (QALYs). A strategy was considered cost effective if it had an incremental cost-effectiveness ratio of less than $100,000 per QALY. Univariable and multivariable sensitivity analyses were performed to assess the robustness of the model to changes in the baseline assumptions. RESULTS: With a baseline assumption of vaccine cost at $47.75, Tdap vaccination was cost effective at $7,601 per QALY. The vaccination strategy was associated with a decrease of 22 infant deaths, 11 infant encephalopathy cases, 2,018 infant hospitalizations, 6,164 infant pertussis infections, and 8,585 maternal pertussis infections, with an increase of 19,489 QALYs. In sensitivity analyses, the strategy was cost effective until the incidence of maternal pertussis became lower than 1.6 cases per 10,000 individuals, the cost of the Tdap vaccine was greater than $540, or previous pertussis immunity was present in more than 92.1% of pregnant individuals. CONCLUSION: In a theoretical U.S. cohort of 3.66 million pregnant individuals, Tdap vaccination during pregnancy is cost effective and reduces infant morbidity and mortality compared with no vaccination during pregnancy. These findings are especially relevant given that approximately half of individuals are not vaccinated during pregnancy and recent data have shown that postpartum maternal vaccination and cocooning strategies are ineffective. Public health strategies to encourage greater uptake of Tdap vaccination should be used to reduce the morbidity and mortality of pertussis infection.

ABSTRACT

OBJECTIVE: To assess the cost effectiveness of universal repeat screening for human immunodeficiency virus (HIV) infection in the third trimester of pregnancy. METHODS: A decision-analytic model was constructed to compare two strategies: screening for HIV infection in the first trimester alone compared with the addition of repeat screening in the third trimester. Probabilities, costs, and utilities were derived from the literature and varied in sensitivity analyses. The assumed incidence of HIV infection in pregnancy was 0.0145% or 14.5 per 100,000. Outcomes included costs (in 2022 U.S. dollars), maternal and neonatal quality-adjusted life-years (QALYs), and cases of neonatal HIV infection. Our theoretical cohort contained 3.8 million pregnant individuals, the approximate number of births per year in the United States. The willingness-to-pay threshold was set at $100,000/QALY. We performed univariable and multivariable sensitivity analyses to determine inputs that most influenced the model. RESULTS: Universal third-trimester screening prevented 133 cases of neonatal HIV infection in this theoretical cohort. Universal third-trimester screening led to an increased cost of $17.54 million and 2,732 increased QALYs, with an incremental cost-effectiveness ratio of $6,418.56 per QALY, less than the willingness-to-pay threshold. In a univariate sensitivity analysis, third-trimester screening remained cost effective with variation of HIV incidence in pregnancy to as low as 0.0052%. CONCLUSION: In a theoretical U.S.-based cohort of pregnant individuals, universal repeat screening for HIV infection in the third trimester was found to be cost effective and to reduce vertical transmission of HIV. These results merit consideration of a broader HIV-screening program in the third trimester.

ABSTRACT

BACKGROUND: Medical abortion provided via telemedicine is becoming more widely available, potentially decreasing travel time for in-person abortion evaluation. METHODS: We conducted a retrospective chart review of all outpatient medical abortions from October 2016 through December 2019 at our academic medical centre in Portland, Oregon, USA. Using mifepristone administration logs, we identified patients who underwent abortion via direct-to-patient telemedicine or in clinic. Both groups had pre-abortion ultrasound examination. We extracted patient characteristics and geographic data to compare travel distance to clinic, ultrasound facility, and nearest advertised abortion clinic. We compared time from first contact until mifepristone ingestion and gestational age at mifepristone ingestion. RESULTS: Median distance from mailing address to clinic for 80 telemedicine and 124 clinic medical abortions was 95 (range 4-377) and 12 (range 0-184) miles (p<0.01). Distance travelled to ultrasound facility was shorter for telemedicine patients (median 7 miles, range 0-150 vs 12 miles, range 0-184; p<0.01) excluding outliers >200 miles. Distance to nearest advertised abortion clinic was equal between groups (median 7 miles, p=0.4). Time to mifepristone administration (ingestion) was longer (11 vs 6 days; p<0.01) and median gestational age was higher (49 vs 44 days; p=0.01) for telemedicine. CONCLUSIONS: Telemedicine increases the reach of abortion providers and provides care to more geographically distant patients. Patients chose telemedicine abortion even when they had an equidistant option, suggesting that patients value telemedicine for reasons other than geographic convenience. This telemedicine delivery model that included ultrasound testing prior to abortion resulted in up to a 5-day delay in abortion initiation, which was not clinically significant.

ABSTRACT

BACKGROUND: Syphilis infections affect many pregnant women worldwide every year. The increasing rates of maternal and congenital syphilis infections in recent years in the United States necessitates further investigation into the adverse effects of syphilis infection on maternal and neonatal health. OBJECTIVE: We sought to examine the association of maternal syphilis infection with adverse pregnancy and perinatal outcomes. METHODS: We performed a retrospective cohort study of women with singleton pregnancies who delivered between 23 and 42 weeks in California between 2007 and 2011. We compared demographic characteristics and pregnancy outcomes between pregnant women with syphilis and without syphilis. Maternal outcomes of interest included gestational hypertension, pre-eclampsia, gestational diabetes, preterm delivery, cesarean delivery, induction of labor, and severe maternal morbidity. Neonatal outcomes included neonatal intensive care unit admission, congenital anomaly, congenital syphilis, small for gestational age, stillbirth, neonatal death, infant death. Descriptive statistics were assessed using chi-square/Fisher's Exact tests. Multivariable logistic regression was used to estimate the association between syphilis and adverse pregnancy and perinatal outcomes. Statistical comparisons with a p-value of less than .05 and 95% CI that did not cross the null were considered statistically significant. RESULTS: Among a cohort of 2,566,246 women, there were 991 pregnancies complicated by maternal infection with syphilis (0.04%). We found during multivariable logistic regression that syphilis infection was significantly associated with preterm delivery (aOR: 1.27, 95% CI: 1.05-1.54), NICU admission >24 h (aOR: 2.54, 95% CI: 2.13-3.04) and stillbirth (aOR: 5.01, 95% CI: 3.16-7.92) after adjusting for a number of potential confounders including maternal age, race/ethnicity, education, parity, prenatal visits, body mass index, smoking and insurance status. CONCLUSION: Maternal syphilis infection in pregnancy is associated with specific adverse pregnancy outcomes, even after adjusting for potential confounders. These data can be used to counsel patients with syphilis in pregnancy, and in developing approaches to clinical care. Due to the increased risk of stillbirth, perhaps such patients should receive antenatal testing. Further research is necessary to investigate the mechanisms of morbidity.

ABSTRACT

BACKGROUND: Patients undergoing systemic therapy for urothelial carcinoma (UC) are at increased risk for venous thromboembolic (VTE) events. The objective of the current study was to determine the rate of VTE events in patients undergoing systemic therapy for UC and assess factors affecting this rate. METHODS: This study was registered with the PROSPERO database (CRD42015025774). We searched Pubmed, MEDLINE, EMBASE, The Cochrane Library, CINAHL, and Web of Science libraries through August 2014. As per PRISMA guidelines, 2 reviewers independently reviewed titles and abstracts. Disagreements were arbitrated by a third reviewer. After full text review, data were abstracted and pooled using a random effects model. Authors were contacted for clarification of data. To determine VTE risk factors, subgroup analyses and meta-regression were conducted. RESULTS: We identified 3,635 publications in the initial search, of which 410 met inclusion criteria for full text review. Of these, we were able to obtain data on the outcome of interest for 62 publications. A total of 5,082 patients, of which 77% were male, underwent systemic therapy for UC, with 373 VTE events. The proportion of patients who had had prior surgery, chemotherapy, or radiation was 55%, 25%, and 9%, respectively. Fixed effects and random effects models were used to estimate the VTE rate, yielding event rates of 6.7% and 5.4%, respectively. CONCLUSIONS: VTE occurs frequently in patients undergoing systemic therapy for UC. The VTE rate was affected by the country of origin, history of radiation, as well as by the systemic treatment class. The study was limited by the incomplete reporting of all variables of interest.
