Obstacles to Accepting Care: Understanding Why Obstetric Patients Leave against Medical Advice.

INTRODUCTION: Discharge "against medical advice" (AMA) in the obstetric population is overall under-studied but disproportionally affects marginalized populations and is associated with worse perinatal outcomes. Reasons for discharges AMA are not well understood. The objective of this study is to identify the obstacles that prevent obstetric patients from accepting recommended care and highlight the structural reasons behind AMA discharges. METHODS: Electronic health records of patients admitted to antepartum, peripartum, or postpartum services between 2008 and 2018 who left "AMA" were reviewed. Progress notes from clinicians and social workers were extracted and analyzed. Reasons behind discharge were categorized using qualitative thematic analysis. RESULTS: Fifty-seven (0.12%) obstetric patients were discharged AMA. Reasons for discharge were organized into two overarching themes: extrinsic (50.9%) and intrinsic (40.4%) obstacles to accepting care. Eleven participants (19.3%) had no reason documented for their discharge. Extrinsic obstacles included childcare, familial responsibilities, and other obligations. Intrinsic obstacles included disagreement with provider regarding medical condition or plan, emotional distress, mistrust or discontent with care team, and substance use. DISCUSSION: The term "AMA" casts blame on individual patients and fails to represent the systemic barriers to staying in care. Obstetric patients were found to encounter both extrinsic and intrinsic obstacles that led them to leave AMA. Healthcare providers and institutions can implement strategies that ameliorate structural barriers. Partnering with patients to prevent discharges AMA would improve maternal and infant health and progress towards reproductive justice.

Comprehensive pregnancy monitoring with a network of wireless, soft, and flexible sensors in high- and low-resource health settings.

Vital signs monitoring is a fundamental component of ensuring the health and safety of women and newborns during pregnancy, labor, and childbirth. This monitoring is often the first step in early detection of pregnancy abnormalities, providing an opportunity for prompt, effective intervention to prevent maternal and neonatal morbidity and mortality. Contemporary pregnancy monitoring systems require numerous devices wired to large base units; at least five separate devices with distinct user interfaces are commonly used to detect uterine contractility, maternal blood oxygenation, temperature, heart rate, blood pressure, and fetal heart rate. Current monitoring technologies are expensive and complex with implementation challenges in low-resource settings where maternal morbidity and mortality is the greatest. We present an integrated monitoring platform leveraging advanced flexible electronics, wireless connectivity, and compatibility with a wide range of low-cost mobile devices. Three flexible, soft, and low-profile sensors offer comprehensive vital signs monitoring for both women and fetuses with time-synchronized operation, including advanced parameters such as continuous cuffless blood pressure, electrohysterography-derived uterine monitoring, and automated body position classification. Successful field trials of pregnant women between 25 and 41 wk of gestation in both high-resource settings (n = 91) and low-resource settings (n = 485) demonstrate the system's performance, usability, and safety.

Factors Associated with the Uptake of Long-acting Reversible Contraception and Contraceptive Use in Postpartum People with HIV at a Single Tertiary Care Center.

OBJECTIVE: This study aimed to elucidate factors contributing to uptake of highly effective contraception, including permanent contraception, and no contraceptive plan among postpartum people with HIV (PWHIV). STUDY DESIGN: A retrospective cohort analysis was conducted to correlate postpartum birth control (PPBC) with sociodemographic and biomedical variables among postpartum PWHIV who received care at The Ruth M. Rothstein CORE Center and delivered at John H. Stroger, Jr. Hospital of Cook County in Chicago, from 2012 to 2020. RESULTS: Earlier gestational age (GA) at initiation of prenatal care, having insurance, and increased parity are associated with uptake of highly effective contraception. Meanwhile, later GA at presentation increased odds of having no PPBC plan. CONCLUSION: Early prenatal care, adequate insurance coverage, and thorough PPBC counseling are important for pregnant PWHIV. KEY POINTS: · Contraceptive use among PWHIV is poorly understood.. · Having insurance and increased parity are associated with long-acting reversible contraception use.. · Earlier GA at first prenatal care visit is associated with increased PPBC uptake..

Intimate Partner Violence Detected during Abortion-Related Visits: A Systematic Review of Screenings and Interventions.

OBJECTIVE: To perform a systematic review of screening tools and interventions focused on reducing adverse health outcomes associated with intimate partner violence (IPV) at abortion-related visits. STUDY DESIGN: Studies were eligible if they included individuals seeking pregnancy options health care services in the United States, screening for or implementation of an intervention for IPV, and were published in English after the year 2000. The primary outcomes were to summarize screening tools, interventions studied, and if interventions led to individuals being connected to IPV-related resources. Secondary outcomes included patient responses to the IPV-related interventions and any other outcomes reported by the studies (PROSPERO #42021252199). RESULTS: Among 4,205 abstracts identified, nine studies met inclusion criteria. The majority (n = 6) employed the ARCHES (Addressing Reproductive Coercion in Health Settings) tool for identification of IPV. Interventions included provider-facilitated discussions of IPV, a safety card with information about IPV and community-based resources, and referral pathways to directly connect patients with support services. For the primary outcome, IPV-related interventions were shown to better inform patients of available IPV-related resources as compared to no intervention at all. For the secondary outcomes, screening and intervening on IPV were associated with improvements in patient perception of provider empathy (i.e., caring about safety) and safer responses by patients to unhealthy relationships. CONCLUSION: Screening for and intervening on IPV at abortion-related visits are associated with positive outcomes for patient safety and the patient-provider relationship. However, data on effective tools for identifying and supporting these patients are extremely limited. This review emphasizes the unmet need for implementation and evaluation of IPV-specific interventions during abortion-related clinical encounters. KEY POINTS: · The abortion visit offers a crucial setting to address IPV among a highly affected population.. · This study reviews others that analyzed interventions and associated outcomes for IPV at abortion-related visits.. · Appropriate interventions for IPV can improve patient-provider relationships and connect patients to essential resources..

The value and limitations of using predetermined criteria in decision making for maternal-fetal interventions.

Maternal-fetal interventions-such as prenatal fetal myelomeningocele (MMC) repair-are at the forefront of clinical innovation within maternal-fetal medicine, pediatric surgery, and neonatology. Many centers determine eligibility for innovative procedures using pre-determined inclusion and exclusion criteria based on seminal studies, for example, the "Management of Myelomeningocele Study" for prenatal MMC repair. What if a person's clinical presentation does not conform to predetermined criteria for maternal-fetal intervention? Does changing criteria on a case-by-case basis (i.e., ad hoc) constitute an innovation in practice and flexible personalized care or transgression of commonly held standards with potential negative consequences? We outline principle-based, bioethically justified answers to these questions using fetal MMC repair as an example. We pay special attention to the historical origins of inclusion and exclusion criteria, risks and benefits to the pregnant person and the fetus, and team dynamics. We include recommendations for maternal-fetal centers facing these questions.

Predictors of Preexposure Prophylaxis Eligibility among Pregnant People with Opioid Use Disorder.

OBJECTIVE: We seek to evaluate risk factors for eligibility for preexposure prophylaxis (PrEP) among pregnant people with opioid use disorder (OUD). STUDY DESIGN: This is a single-site retrospective cohort study of pregnant people admitted for management of OUD at an urban, tertiary care center from 2013 to 2022. PrEP eligibility was defined based on (1) modified American College of Obstetricians and Gynecologists' (ACOG) 2014 criteria: diagnosis of a sexually transmitted infection (STI), engagement in transactional sex work, intravenous drug use (IVDU), or incarceration and (2) modified 2021 Centers for Disease Control (CDC) criteria: diagnosis of bacterial STI (e.g., gonorrhea or syphilis) or transactional sex work. Risk factors associated with PrEP eligibility were evaluated using chi- square or Fischer's exact tests for categorical variables and t-tests or Wilcoxon rank-sum tests for continuous variables. Multivariable regression was used to control for confounding covariates, defined as p < 0.10 on bivariate analysis. p < 0.05 was used to indicate statistical significance. RESULTS: A total of 132 individuals met inclusion criteria, of whom 101 (76.5%) were deemed eligible for PrEP by meeting one or more modified 2014 ACOG criteria: 42 (31.8%) were incarcerated or had one or more STIs, while 30 (22.7%) endorsed engaging in transactional sex work and 68 (58.6%) endorsed IVDU. Using modified 2021 CDC criteria, 37 (28%) met PrEP eligibility, with 12 (9.1%) diagnosed specifically with a bacterial STI and 30 (22.7%) engaging in transactional sex work. Only comorbid psychiatric illness was associated with an increased risk for PrEP eligibility based on 2014 criteria, which persisted after controlling for maternal race/ethnicity (aRR 1.52, 95% confidence interval [CI] 1.24-1.86), and 2021 criteria, which persisted after controlling for nulliparity (aRR 2.12, 95% CI 1.30-3.57). CONCLUSION: A significant number of pregnant people with OUD meet one or more criteria for PrEP, with comorbid psychiatric conditions increasing the risk of meeting criteria. KEY POINTS: · Comorbid psychiatric illness is significantly associated with high risk of PrEP eligibility.. · A large proportion of pregnant individuals with active OUD meet criteria for PrEP prescribing.. · Risk-based screening algorithms for PrEP eligibility have limitations..

Hypertension in pregnancy and adverse outcomes among low-risk nulliparous women expectantly managed at or after 39 weeks: a secondary analysis of a randomised controlled trial.

OBJECTIVE: To evaluate whether hypertensive disorders of pregnancy (HDP) among low-risk nulliparous women expectantly managed at or after 39 weeks of gestation are associated with adverse outcomes. DESIGN: Secondary analysis of a randomised trial. SETTING: Multicentre, USA. POPULATION: Individuals in the expectantly managed group who delivered on or after 39 weeks. METHODS: Multivariable analysis to estimate adjusted relative risks (aRR) for binomial outcomes, adjusted odds ratios (aOR) for multinomial outcomes and 95% CI. MAIN OUTCOME MEASURES: Composite adverse maternal outcome including placental abruption, pulmonary oedema, postpartum haemorrhage, postpartum infection, venous thromboembolism or intensive care unit admission. Secondary outcomes included a composite of perinatal death or severe neonatal complications, mode of delivery, small and large for gestational age and neonatal intermediate or intensive unit length of stay. RESULTS: Of the 3044 women randomised to expectant management in the original trial, 2718 (89.3%) were eligible for this analysis, of whom 373 (13.7%) developed HDP. Compared with participants who remained normotensive, those who developed HDP were more likely to experience the maternal composite (12% versus 6%, aRR 1.84, 95% CI 1.33-2.54) and caesarean delivery (29% versus 23%, aOR 1.32, 95% CI 1.01-1.71). Differences between the two groups were not significantly different for the adverse perinatal composite (7% versus 5%, aRR 1.38, 95% CI 0.92-2.07) or for other secondary outcomes. CONCLUSION: Almost 14% of low-risk nulliparous individuals expectantly managed at 39 weeks developed HDP, and were more likely to experience adverse maternal outcomes compared with those who did not develop HDP. TWEETABLE ABSTRACT: Almost 14% of low-risk nulliparous individuals expectantly managed at 39 weeks developed hypertensive disorders of pregnancy, and were more likely to experience adverse maternal outcomes compared with those who did not develop hypertensive disorders.

Predictive Factors Associated with Naloxone Prescription among Pregnant People Admitted for the Management of Opioid Use Disorder.

OBJECTIVE: Our objective was to examine the biomedical and sociodemographic factors associated with the prescription of naloxone among pregnant people with opioid-use disorder (OUD) who were admitted for initiation of medications for OUD (i.e., buprenorphine-containing medications or methadone) following the implementation of a statewide initiative focused on reducing adverse perinatal health outcomes. STUDY DESIGN: This is a single-site, retrospective cohort study of pregnant people admitted for the management of OUD at an urban, tertiary care center between 2013 and 2020. The primary outcome is evidence of a prescription of naloxone, ascertained from the electronic medical record. Bivariate and multivariable logistic regression modeling was performed to evaluate biomedical and sociodemographic variables associated with a prescription for naloxone. Covariates for inclusion in the multivariate logistic regression model were selected based on a p < 0.05 on bivariate analysis. Statistical significance was set at p < 0.05. RESULTS: One hundred and thirty-nine participants met the inclusion criteria. On bivariate analysis, people who received naloxone were more likely to be admitted after the initiation of a statewide initiative focused on reducing adverse perinatal outcomes associated with perinatal OUD. Those individuals reporting intravenous drug use (IVDU) were less likely to receive naloxone. On multivariate logistic regression, after controlling for IVDU and epoch of admission, both IVDU (adjusted odds ratio [aOR]: 0.27, 95% confidence interval [CI]: 0.11-0.70) and epoch of admission (aOR: 3.48, 95% CI: 1.28-9.50) were independently associated with receipt of prescription of take-home naloxone. CONCLUSION: Naloxone prescription was independently associated with the epoch of admission and route of drug administration. These data can be useful in the evaluation and development of clinical practices to increase rates of naloxone prescription in pregnant people with OUD admitted for inpatient management. KEY POINTS: · Thirty four percent of individuals with perinatal OUD were prescribed take-home naloxone (THN).. · Epoch of admission and route of drug administration were independently associated with THN.. · These data can be used to guide public health and clinical programming for pregnant people..

Race/Ethnicity and Perception of Care: Does Patient-Provider Concordance Matter?

OBJECTIVE: We determine whether racial concordance between postpartum patients and obstetric providers (dyads) impacts the perception of quality of care among people undergoing intrapartum obstetrical procedures. STUDY DESIGN: This is a prospective cohort study of postpartum people who underwent operative vaginal or cesarean deliveries in the second stage of labor. Participants were asked to identify the race of their primary provider and complete the Interpersonal Processes of Care (IPC) survey, which assesses communication, patient-centered decision-making, and interpersonal style. The association of participant-identified patient-provider racial concordance with IPC scores was determined. The primary outcome was the IPC subdomain related to discrimination, and secondary outcomes included other IPC subdomains and IPC results by participant racial identity (Black, LatinX vs. White). Sociodemographic and biomedical data were extracted from the medical record. Bivariable analyses were performed. RESULTS: Of 168 patients who were approached, 107 (63.6%) agreed to participate and 87 (81.3%) completed the survey. The majority (n=49) identified a racially discordant provider. Participants in racially concordant dyads were more likely to be older, White, use English as a primary language, complete a higher degree of education, and have a higher household income when compared with racially discordant dyads. Intrapartum outcomes were not significantly different between groups. Median IPC subtest scores were not significantly different between groups or between racial/ethnic identities. CONCLUSION: There were no significant differences in perceptions of IPC between racially concordant versus discordant dyads. However, there is an ongoing need to further clarify measures of quality of care in high-acuity obstetrical situations to remediate ongoing racial and ethnic disparities in adverse health outcomes. KEY POINTS: · Racial concordance between patient and clinician has been associated with improved quality of care.. · There are limited data on racial concordance and perceptions of operative obstetrical care (e.g., operative vaginal delivery).. · Racial concordance was not associated with differences in patient-perceived quality of care associated with operative obstetrics..

Selective Fetoscopic Laser Photocoagulation or Expectant Management for Stage I Twin-Twin Transfusion: A Cost-Effectiveness Analysis.

BACKGROUND: Selective fetoscopic laser photocoagulation (SFLP) is the preferred intervention for stage II-IV twin-twin transfusion syndrome (TTTS); however, there is no consensus on whether SFLP or expectant management (EM) is the preferred strategy to manage Quintero stage I TTTS. OBJECTIVE: The objective of this study is to estimate whether SFLP or EM is the cost-effective strategy for management of Quintero stage I TTTS. STUDY DESIGN: A decision-analysis (DA) model compared SFLP to EM for 1,000 pregnant people with monochorionic-diamniotic twins affected by stage I TTTS. All subjects were assumed to be appropriate candidates for either SFLP or EM. Probabilities, costs, and utilities were derived from the literature. The DA was conducted from a healthcare payor perspective, and the analytic horizon was over the course of an offspring's lifetime, with primary outcomes of survivorship (i.e., no intrauterine fetal demise or neonatal death) and long-term neurodevelopmental impairment. The model incorporated Markov processes with 4-week cycles throughout pregnancy. Incremental cost-effectiveness ratios (ICER) for each strategy were calculated and compared to estimate marginal cost effectiveness. An ICER of USD 100,000 per quality-adjusted life year was used to define the cost-effectiveness threshold. One-way sensitivity and Monte Carlo analyses (MCA), as well as microsimulations, were performed. RESULTS: For base-case estimates, SFLP was found to be cost-effective compared to EM in the management of stage I TTTS. In one-way sensitivity analysis, varying each variable along pre-specified ranges did not result in changes in the conclusion. MCA projects SFLP as the cost-effective strategy in 100% of runs. CONCLUSIONS: With base-case estimates, SFLP is estimated to be the cost-effective strategy for the treatment of Quintero stage I TTTS when compared with EM. This remained true across a wide range of inputs.

Social Vulnerability among Foreign-Born Pregnant Women and Maternal Virologic Control of HIV.

OBJECTIVE: The aim of this study was to assess whether social vulnerability among foreign-born pregnant women living with HIV is associated with maternal viremia during pregnancy. STUDY DESIGN: This retrospective cohort study included all foreign-born pregnant women living with HIV who received prenatal care in a multidisciplinary prenatal clinic between 2009 and 2018. A licensed clinical social worker evaluated all women and kept detailed clinical records on immigration status and social support. Social vulnerability was defined as both living in the United States for less than 5 years and reporting no family or friends for support. The primary outcome was evidence of viral non-suppression after achievement of initial suppression. Secondary outcomes were the proportion of women who required > 12 weeks after starting antiretroviral therapy to achieve viral suppression, median time to first viral suppression (in weeks) after initiation of antiretroviral therapy, and the proportion who missed ≥ 5 doses of antiretroviral therapy. Bivariable analyses were performed. RESULTS: A total of 111 foreign-born women were eligible for analysis, of whom 25 (23%) were classified as socially vulnerable. Social and clinical characteristics of women diverged by social vulnerability categorization but no differences reached statistical significance. On bivariable analysis, socially-vulnerable women were at increased risk for needing > 12 weeks to achieve viral suppression (relative risk: 1.78, 95% confidence interval: 1.18-2.67), though there was no association with missing ≥ 5 doses of antiretroviral therapy or median time to viral suppression after initiation of antiretroviral therapy. CONCLUSION: Among foreign-born, pregnant women living with HIV, markers of virologic control during pregnancy were noted to be worse among socially-vulnerable women. Insofar as maternal viremia is the predominant driver of perinatal transmission, closer clinical surveillance and support may be indicated in this population. KEY POINTS: · 23% of foreign-born pregnant women living with HIV were identified as socially vulnerable.. · Socially-vulnerable women were at higher risk for re-emergent viremia (24 vs. 7%, RR 3.44).. · Socially-vulnerable women were at higher risk for needing >12 weeks to become aviremic (64 vs. 36%, RR: 1.7)..

Postpartum NSAID Use and Adverse Outcomes among Women with Hypertensive Disorders of Pregnancy: A Systematic Review and Meta-analysis.

OBJECTIVE: This study was aimed to perform a systematic review and meta-analysis of the association between postpartum nonsteroidal anti-inflammatory drug (NSAID) use among women with hypertensive disorders of pregnancy (HDP) and risks of adverse postpartum outcomes. STUDY DESIGN: Studies were eligible if they included women who had been diagnosed with HDP and were postpartum, reported exposure to NSAIDs, were written in English, and were published between January 2000 and November 2019. Assessment of bias was performed using the Newcastle-Ottawa scale for observational studies or the Cochrane Collaborative tool for randomized trials. The primary outcome was maternal blood pressure ≥ 150 mm Hg systolic and/or 100 mm Hg diastolic. Secondary outcomes were persistent blood pressures ≥ 160 mm Hg systolic and/or 110 mm Hg diastolic, mean arterial pressure (MAP), initiation or up-titration of antihypertensive medication, length of hospital stay, rehospitalization for blood pressure control, and postpartum opioid use. A random-effect meta-analysis was performed using RevMan, with a p-value < 0.05 used to indicate statistical significance (PROSPERO CRD no.: 42019127043). RESULTS: Among 7,395 abstracts identified, seven studies (four randomized and three cohort studies, n = 777 patients) met inclusion criteria. All cohort analyses exhibited low levels of bias, while two randomized controlled trials exhibited a high risk of bias in blinding and inclusion criteria. There was no association between NSAID use and blood pressures ≥ 150 mm Hg systolic and/or 100 mm Hg diastolic (risk ratio [RR]: 1.21, 95% confidence interval [CI]: 0.89-1.64). Conversely, NSAID use was associated with a statistically significant, but clinically insignificant, increase in length of postpartum stay (0.21 days, 95% CI: 0.05-0.38). No other secondary outcomes were significantly different between groups. CONCLUSION: Postpartum NSAID use among women with HDP was not associated with maternal hypertension exacerbation. These findings support the recent American College of Obstetricians and Gynecologists' guideline change, wherein preeclampsia is no longer a contraindication to postpartum NSAID use. KEY POINTS: · Postpartum (PP) NSAID use does not worsen hypertension in preeclampsia.. · PP NSAID use is associated with a longer, though clinically insignificant, length of stay.. · Our findings support ACOG's recommendations for PP NSAID use..

Home Birth in the Era of COVID-19: Counseling and Preparation for Pregnant Persons Living with HIV.

With the coronavirus disease 2019 (COVID-19) pandemic in the United States, a majority of states have instituted "shelter-in-place" policies effectively quarantining individuals-including pregnant persons-in their homes. Given the concern for COVID-19 acquisition in health care settings, pregnant persons with high-risk pregnancies-such as persons living with HIV (PLHIV)-are increasingly investigating the option of a home birth. Although we strongly recommend hospital birth for PLHIV, we discuss our experience and recommendations for counseling and preparation of pregnant PLHIV who may be considering home birth or at risk for unintentional home birth due to the pandemic. We also discuss issues associated with implementing a risk mitigation strategy involving high-risk births occurring at home during a pandemic. KEY POINTS: · Coronavirus disease 2019 pandemic has increased interest in home birth.. · Women living with HIV are pursuing home birth.. · Safe planning is paramount for women living with HIV desiring home birth, despite recommending against the practice..

"A Résumé for the Baby": Biosocial Precarity and Care of Substance-Using, Pregnant Women in San Francisco.

In the United States, the historical condemnation and punitive legal consequences of substance use during pregnancy-ranging from incarceration to termination of parental custody of a newborn-render pregnant women in state of biosocial precarity. Yet pregnant women who use illicit substances who desire to parent must generate a legible narrative for bureaucratic groups, such as Child Protective Services, through engagement with biomedical care in order to demonstrate parental capacity. Based on longitudinal interviews with pregnant women who were actively using illicit substances and attempting to parent after delivery, we posit that the relationship between biosocial precarity and biomedical care is a procedural interaction that is rooted in the potential to parent, described as the ability to have a "take-home baby." In order to achieve this goal, the need for engagement in biomedical care and the creation of a biomedical narrative, described as a "résumé for the baby" is required. The relationship between care and biosocial precarity is a unique, underdeveloped concept within medical anthropology and has important consequences not only for the ethical turn within anthropology, but also how applied researchers consider engagement with this highly marginalized, vulnerable population.

Hypertensive Disorders of Pregnancy and Preterm Birth Rates among Black Women.

OBJECTIVE: The objective of this study was to investigate the role of gestational hypertension (gHTN) and chronic hypertension (cHTN) on rates of preterm birth (PTB) among black women. STUDY DESIGN: Singleton live births between 20 and 44 weeks' gestation among black women in California from 2007 to 2012 were used for analysis. Risk of PTB by subtype and gestational age among women with cHTN or gHTN, including preeclampsia, was calculated via Poisson's logistic regression modeling. Risks were adjusted for maternal factors associated with increased risk of PTB. RESULTS: A total of 154,950 women met the inclusion criteria. Of the 5,948 women in the sample with cHTN, 26.2% delivered preterm; for the 11,728 women with gHTN, 21.6% delivered preterm. Women with gHTN or cHTN had a higher risk of medically indicated and spontaneous PTB, both at less than 32 and 32 to 36 weeks, when compared with nonhypertensive women (adjusted relative risks [aRRs]: 3.4-11.6). Women with superimposed preeclampsia had higher risks of spontaneous (aRR: 2.8, 95% confidence interval [CI]: 2.3-3.4) and medically indicated PTB (aRR: 2.8, 95% CI: 2.0-3.8), especially PTB < 32 weeks, when compared with women with preeclampsia. CONCLUSION: Among black women, superimposed preeclampsia increased the risk for spontaneous and medically indicated PTB, especially PTB < 32 weeks.

The interaction between maternal race/ethnicity and chronic hypertension on preterm birth.

BACKGROUND: In both the biomedical and public health literature, the risk for preterm birth has been linked to maternal racial/ethnic background, in particular African-American heritage. Despite this well-documented health disparity, the relationship of comorbid conditions, such as chronic hypertension, to maternal race/ethnicity and preterm birth has received relatively limited attention in the literature. OBJECTIVE: The objective of the study was to evaluate the interaction between chronic hypertension and maternal racial/ethnic background on preterm birth. STUDY DESIGN: This is a retrospective cohort study of singleton pregnancies among women who delivered between 2002 and 2015 at the University of California, San Francisco. The associations of chronic hypertension with both spontaneous and medically indicated preterm birth were examined by univariate and multivariate logistical regression, adjusting for confounders including for maternal age, history of preterm birth, maternal body mass index, insurance type (public vs private), smoking, substance abuse, history of pregestational diabetes mellitus, and use of assisted reproductive technologies. The interaction effect of chronic hypertension and racial/ethnicity was also evaluated. All values are reported as odds ratios, with 95% confidence intervals and significance set at P = .05. RESULTS: In this cohort of 23,425 singleton pregnancies, 8.8% had preterm deliveries (3% were medically indicated preterm birth, whereas 5.5% were spontaneous preterm births), and 3.8% of women carried the diagnosis of chronic hypertension. Chronic hypertension was significantly associated with preterm birth in general (adjusted odds ratio, 2.74, P < .001) and medically indicated preterm birth specifically (adjusted odds ratio, 5.25, P < .001). When evaluating the effect of chronic hypertension within racial/ethnic groups, there was an increased odds of a preterm birth among hypertensive, African-American women (adjusted odds ratio, 3.91, P < .001) and hypertensive, Asian-American/Pacific Islander women (adjusted odds ratio, 3.51, P < .001) when compared with their nonhypertensive counterparts within the same racial/ethnic group. These significant effects were also noted with regard to medically indicated preterm birth for hypertensive African-American women (adjusted odds ratio, 6.85, P < .001) and Asian-American/Pacific Islander women (adjusted odds ratio, 9.87, P < .001). There was no significant association of chronic hypertension with spontaneous preterm birth (adjusted odds ratio, 0.87, P = .4). CONCLUSION: The effect of chronic hypertension on overall preterm birth and medically indicated preterm birth differs by racial/ethnic group. The larger effect of chronic hypertension among African-American and Asian/Pacific Islander women on medically indicated and total preterm birth rates raises the possibility of an independent variable that is not captured in the data analysis, although data regarding the indication for medically indicated preterm delivery was limited in this data set. Further investigation into both social-structural and biological predispositions to preterm birth should accompany research focusing on the effect of chronic hypertension on birth outcomes.

Rethinking the social history in the era of biolegitimacy: global health and medical education in the care of Palestinian and Syrian refugees in Beirut, Lebanon.

The critiques leveled towards medical humanitarianism by the social sciences have yet to be felt in medical education. The elevation of biological suffering, at the detriment of sociopolitical contextualization, has been shown to clearly impact both acute and long-term care of individuals and communities. With many medical students spending a portion of their educational time in global learning experiences, exposure to humanitarianism and its consequences becomes a unique component of biomedical education. How does the medical field reconcile global health education with the critiques of humanitarianism? This paper argues that the medical response to humanitarian reason should begin at the level of a social history. Using experiential data culled from fieldwork with Palestinian and Syrian refugees in Lebanon, the authors argue that an expanded social history, combined with knowledge derived from the social sciences, can have significant clinical implications. The ability to contextualize an individual's disease and life within a complex sociopolitical framework means that students must draw on disciplines as varied as anthropology, sociology, and political history to further their knowledge base. Moreover, situating these educational goals within the framework of physician advocacy can build a strong base in medical education from both a biomedical and activist perspective.
