Indication Creep of Antenatal Late Preterm Steroids.

OBJECTIVE: While antenatal corticosteroids (ACS) administered in the late preterm period have been shown to reduce respiratory morbidity, this finding was demonstrated in a well-designed randomized controlled trial (the Antenatal Betamethasone for Women at Risk for Late Preterm Delivery [ALPS]) with strict inclusion/exclusion criteria that may differ from clinical practice. The aim of this study was to investigate whether there has been indication creep since use of late preterm ACS became standard of care. STUDY DESIGN: Retrospective cohort study of pregnant women who received late preterm ACS between 2016 and 2019 were identified and separated into epochs of 2016 to 2017 and 2018 to 2019 based on year of exposure. The primary outcome was rate of inappropriate ACS exposure, defined as nonadherence to the inclusion/exclusion criteria of the ALPS trial. Secondary outcomes were rates of nonoptimal ACS exposure (delivery >7 days from ACS or term delivery). Logistic regression was used to generate adjusted odds ratios (aORs) between epochs for the primary outcome adjusting for confounders. RESULTS: There were 660 women who received late preterm ACS during the study period with 229 (34.6 %) deemed inappropriate exposures. The most common reason for inappropriate treatment was preterm premature rupture of membrane (PPROM; 29.0%) with exclusionary cervical examination or contraction frequency. No difference was observed in inappropriate ACS exposure between epochs (aOR = 0.83, 95% confidence interval [CI]: 0.59-1.2). However, there was a reduction in nonoptimal exposure over time (aOR = 0.67, 95% CI: 0.47-0.97) . Women receiving inappropriate ACS were more likely to deliver at term if indicated for maternal/fetal status (50.0 vs. 19.5%, p < 0.001) and preterm labor (66.0 vs. 41.9%; p = 0.015). Further, inappropriate exposure in preterm labor had higher rates of exposure latency >7 days (62.3 vs. 39.1%, p = 0.006) with a longer latency to delivery (3 vs. 16 days; p < 0.001). CONCLUSION: Over one-third of women received late preterm ACS for an indication that could be classified as indication creep. Depending on indication, inappropriate administration is associated with higher rates of nonoptimal exposure. KEY POINTS: · There is potential for indication creep of ACS administration.. · One third of late preterm ACS exposures in our study were inappropriate.. · Utilizing clinical criteria can aid in identifying patients who best benefit from late preterm ACS..

Cost-effectiveness analysis of 2 surveillance options for cervical intraepithelial neoplasia 1.

OBJECTIVE: We aim to determine the difference in cost between 2 accepted surveillance strategies for women diagnosed with cervical intraepithelial neoplasia 1 (CIN 1): repeat cytology at 6 and 12 months versus human papillomavirus (HPV) DNA testing at 12 months. MATERIALS AND METHODS: Extracting data from the literature regarding the natural history of HPV infection and CIN 1, we estimated regression, persistence, and progression rates during a 2-year interval. Costs were based on 2011 Medicaid reimbursements for cytology, biopsy interpretation, HPV testing, and the associated office visit or procedure fee. We constructed a decision tree model to estimate the potential cost benefits of using HPV testing, and sensitivity analyses were performed. Treatment costs for high-grade disease were not included because of equal occurrence in both groups. RESULTS: In a hypothetical cohort of 100 women with CIN 1 (assumed compliant with 2 y of follow-up), the total cost for cytology-based follow-up was $89,969, whereas the total cost for HPV-based follow-up was $37,357. This indicates an average cost savings of $526 per patient in favor of HPV testing. If we then consider the 234,603 incident cases of CIN 1 in the United Sates per year, preferential use of HPV-based follow-up would save $123,429,305. CONCLUSIONS: Although both cytology and HPV testing are sound methods for surveillance of CIN 1, it is more cost-effective to use HPV testing.

Increasing Preterm Delivery and Small for Gestational Age Trends in South Carolina during the COVID-19 Pandemic.

Preterm delivery (PTD) complications are a major cause of childhood morbidity and mortality. We aimed to assess trends in PTD and small for gestational age (SGA) and whether trends varied between race-ethnic groups in South Carolina (SC). We utilized 2015-2021 SC vital records linked to hospitalization and emergency department records. PTD was defined as clinically estimated gestation less than (<) 37 weeks (wks.) with subgroup analyses of PTD < 34 wks. and < 28 wks. SGA was defined as infants weighing below the 10th percentile for gestational age. This retrospective study included 338,532 (243,010 before the COVID-19 pandemic and 95,522 during the pandemic) live singleton births of gestational age ≥ 20 wks. born to 260,276 mothers in SC. Generalized estimating equations and a change-point during the first quarter of 2020 helped to assess trends. In unadjusted analyses, pre-pandemic PTD showed an increasing trend that continued during the pandemic (relative risk (RR) = 1.04, 95% CI: 1.02-1.06). PTD < 34 wks. rose during the pandemic (RR = 1.07, 95% CI: 1.02-1.12) with a significant change in the slope. Trends in SGA varied by race and ethnicity, increasing only in Hispanics (RR = 1.02, 95% CI: 1.00-1.04) before the pandemic. Our study reveals an increasing prevalence of PTD and a rise in PTD < 34 wks. during the pandemic, as well as an increasing prevalence of SGA in Hispanics during the study period.
