{"title":"Prenatal Care Utilization and Birth Outcomes After Expansion of the National Health Service Corps.","authors":"Yanlei Ma, Olesya Baker, Fang Zhang, Carrie Cochran-McClain, Anjali J Kaimal, Hao Yu","doi":"10.1097/AOG.0000000000005704","DOIUrl":"10.1097/AOG.0000000000005704","url":null,"abstract":"<p><strong>Objective: </strong>The National Health Service Corps (NHSC) attracts clinicians to Health Professional Shortage Areas (HPSAs) through scholarships and loan repayments. Since 2009, the NHSC workforce, including maternity care clinicians, has substantially expanded. This study evaluates the association between NHSC expansion and prenatal care and birth outcomes.</p><p><strong>Methods: </strong>In this quasi-experimental study, we adopted a generalized difference-in-differences design to compare changes in prenatal care and birth outcomes from 2005 to 2019 using birth certificate data. Counties designated as HPSAs without any NHSC maternity care clinicians throughout the study period were control counties, and those without such clinicians before 2009 but receiving them after 2009 were treated counties. Outcome measures include a count variable of number of prenatal visits and four dichotomous variables: prenatal care initiation in the first trimester, adequacy of prenatal care, preterm birth, and low birth weight. We estimated negative binomial models for number of prenatal visits and linear probability models for the dichotomous outcomes, adjusting for maternal characteristics, non-NHSC clinician density, and state-level policies. Stratified analyses were also conducted on the basis of birthing people's demographics and county-level characteristics.</p><p><strong>Results: </strong>Our sample comprised 12,980,111 live births between 2005 and 2019 by individuals residing in 1,254 HPSA counties without any NHSC maternity care clinicians before 2009, including 222 counties that received such clinicians after 2009. Compared with control counties, pregnant people in treated counties experienced significant increases in prenatal visits (211 more prenatal visits relative to baseline of 11,226 visits per 1,000 births, P <.001) and in the likelihood of receiving adequate prenatal care (1.43 percentage point increase relative to baseline of 67.0 percentage points, P <.01). Although the NHSC expansion improved prenatal care use for all racial and ethnic groups, pregnant people residing in urban and high social vulnerability areas benefited most. Improvements in birth outcomes were observed only among certain subgroups such as a 0.91 percentage point reduction in preterm birth (relative to baseline of 12.6 percentage points, P <.001) and a 0.87 percentage point reduction in low birth weight (relative to baseline of 8.2 percentage points, P <.05) among pregnant people living in full-county HPSAs.</p><p><strong>Conclusion: </strong>The NHSC expansion since 2009 was associated with increases in prenatal care utilization, particularly among vulnerable populations.

Evaluation for the presence of anti-red cell antibodies should be routinely undertaken at the first prenatal visit. If anti-red cell antibodies are detected, consideration of a consultation or referral to a maternal-fetal medicine specialist with experience in the monitoring and treatment of these patients is warranted. Cell-free DNA can be used to determine fetal red cell antigen status to determine whether the pregnancy is at risk of complications from the red cell antibodies. First-time sensitized pregnancies are followed up with serial maternal titers, and, when indicated, serial Doppler assessment of the peak systolic velocity in the middle cerebral artery should be initiated by 16 weeks of gestation. When there is a history of an affected fetus or neonate, maternal titers are less predictive of fetal risk; if the fetus is antigen positive, serial peak systolic velocity in the middle cerebral artery measurements should be initiated by 15 weeks of gestation because intraperitoneal intrauterine blood transfusions can be used at this gestation if needed. The mainstay of fetal therapy involves intrauterine transfusion through ultrasound-directed puncture of the umbilical cord with the direct intravascular injection of red cells. A perinatal survival rate exceeding 95% can be expected at experienced centers. Neonatal phototherapy and \"top-up\" transfusions attributable to suppressed reticulocytosis often are still required for therapy after delivery.</p>","PeriodicalId":19483,"journal":{"name":"Obstetrics and gynecology","volume":null,"pages":null},"PeriodicalIF":5.7,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141988497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This frequently disadvantages academic specialists in promotion compared with their subspecialty fellowship-trained colleagues. A few research fellowship programs were recently launched to address this issue. However, these programs are not uniform and encounter challenges such as sustainable funding. In this article, building on knowledge from current academic specialist fellowship programs, we discuss the needs, challenges, and proposed solutions. We also propose some details needing further discussion among the academic obstetrics and gynecology community. We discuss how such fellowships can integrate with current development and training opportunities such as the Women's Reproductive Health Research award, Building Interdisciplinary Research Careers in Women's Health award, other K and K-type career development programs, NIH T32 grants, and clinical research courses for obstetricians and gynecologists.
