Lower socioeconomic status (SES) has been associated with hypertension; however, the mediators and moderators of this association remain understudied. We examined the mediation effect of psychological distress on the link between lower SES and self-reported hypertension and the racial and sex moderation effects. We analyzed the data collected from 2009 to 2019 among adults from the Panel Study of Income Dynamics (PSID). Lower SES was defined as one of three indicators: education ≤ 12 years, unemployed, or individual annual income < $27,800. Psychological distress was assessed using the Kessler K6 scale. Cox proportional hazard regression was conducted. Mediation analyses were performed using the PROCESS macro. In the sample of heads of family who did not have self-reported hypertension in 2009 (N = 6,214), the mean age was 41 years, 30.6% were female, 32.9% were African American. The cumulative incidence of self-reported hypertension was 29.8% between 2009 and 2019. Cox proportional hazard regression analysis showed that after controlling for covariates, lower SES (score > 0 vs. score =0) was associated with self-reported hypertension (HR = 1.27, 95% CI = 1.14-1.42). SES had indirect effect on self-reported hypertension through psychological distress and the indirect effect (0.02 in females, 0.01 in males, p < 0.05) was moderated by sex but not by race. The association of SES and self-reported hypertension was mediated by psychological distress and sex moderated the mediation effect. Interventions focused on reducing contributors to SES and psychological stress should be considered to reduce hypertension risk.

Objectives: We aimed to determine the rate of postdischarge adverse events (AEs), classify the types of postdischarge AEs, and identify risk factors for postdischarge AEs among neonates admitted to the neonatal intensive care unit (NICU). Study Design: This was a prospective cohort study of neonates admitted to the NICU from February 2017 through June 2019. We enrolled 170 neonates from a level 4 NICU who were being discharged home and whose parents can speak English and could be contacted after discharge. The main outcome of the study was postdischarge AEs based on structured telephone interviews, health record review, and adjudication by 2 blinded, trained physicians using a previously established methodology. Results: Fourteen percent of 170 neonates admitted to the NICU experienced postdischarge AEs, with 48% being either preventable or ameliorable. Adverse drug events and procedural complications comprised most of the AEs (48%), but most of the preventable and ameliorable AEs were due to management, therapeutic, or diagnostic errors. Seventy-nine percent of neonates who suffered an AE experienced either a readmission to the hospital or an emergency department visit. Neonates admitted to a level 4 NICU from another NICU (level 1, 2, or 3) (adjusted odds ratio, 3.62; 95% confidence interval, 1.27–12.60; P = 0.01) and those 28 to 36 weeks (adjusted odds ratio, 11.38; 95% confidence interval, 1.67–127.98; P = 0.01) had a significantly higher risk of AEs at discharge. Conclusions: Neonates discharged from a level 4 NICU were at high risk for experiencing postdischarge AEs. The identification of AE types and risk factors can be used to guide efforts to develop interventions to improve neonatal patient safety during the postdischarge period.

Introduction: There has been little attention to measuring quality of prenatal care from a Black person's perspective. We examined validity and reliability of the Quality of Prenatal Care Questionnaire (QPCQ) and perceptions of the quality of prenatal care among pregnant Black women.Methods: A total of 190 women had complete data on the postpartum questionnaire containing the QPCQ within 8 weeks after birth. Internal consistency reliability was assessed using Cronbach's α. Construct validity was assessed through hypothesis testing using select questions from the Pregnancy Risk Assessment Monitoring System (PRAMS) and Pearson's r correlation.Results: The mean (SD) maternal age was 26.5 (5.5) years, and 85.3% of births were term (>37 weeks’ 0 days’ gestation). The total mean (SD) QPCQ score was 191.3 (27.9) points (range 46‐230), and the mean (SD) item score for the subscales ranged from 3.88 (0.80) points to 4.27 (0.64). The Cronbach's α for the overall QPCQ score was .97 and ranged from .72 to .96 for the 6 subscale scores, which indicated acceptable internal consistency reliability. All but one subscale had a Cronbach's α higher than .80. The Approachability subscale had a Cronbach's α of .72. Construct validity demonstrated a moderate and significant positive correlation between the PRAMS items and the QPCQ (r = .273, P < .001).Discussion: To our knowledge, this is the first study to examine the validity and reliability of the QPCQ and perceptions of quality of prenatal care among Black women from the United States. The results indicate that participants rate the quality of their prenatal care highly and that the QPCQ is a reliable and valid measure of the quality of prenatal care. Use of a convenient and reliable instrument to measure the quality of prenatal care rather than prenatal care satisfaction or utilization may help to elucidate the factors of prenatal care that are protective specifically among Black women.

Longitudinal data on the associations between sleep disturbances, daytime sleepiness, and daily functioning are limited in the general adolescent population. This study examined the cross-sectional...

Background: The purpose of this study was to implement and evaluate a pharmacist-led hypertension (HTN) program for under-resourced patients discharged from the emergency department (ED) or screened at community health events who are lacking a regular primary care provider (PCP) relationship. Methods: This was a single arm, prospective, pilot study to recruit patients from the Detroit Medical Center (DMC) Sinai Grace Hospital (SGH) ED and community health events. The outpatient pharmacist-led transitional care clinic (TCC) was implemented through a collaborative practice agreement (CPA) with ED physicians. Eligible patients 18 to 60 years with elevated blood pressure (BP) (> 140/90 mmHg) and lacking a PCP relationship were referred to the TCC for HTN management. The primary outcome measure was change in systolic and diastolic BP (SBP and DBP). Difference in BP values was evaluated using Wilcoxon Signed Ranks test and descriptive statistics were used to explain demographic data. Results: There were 116 patients enrolled May 2017 to August 2018; 44 (37.9%) completed visit one [cohort 1], 30 (25.9%) completed at least three visits [cohort 2], and 16 (13.8%) completed five visits [cohort 3]. Most patients were African American (AA) 97.7%, 47.8% were male, and an average of 42.11 (SD 9.70) years. For cohorts 2 and 3, there was significant reduction in BP between TCC visits one and two and the reduction was maintained through five visits for patients that remained in the study. Patients who completed five visits (n=16) showed a significant change from visit one to visit five in SBP of -23 mmHg (p=0.002) and achieved BP goal with an average SBP 139 mmHg (SD 19.33) and DBP 90 mmHg (SD 10.17). Conclusion: The pharmacist-led TCC was successfully implemented. Outpatient pharmacists collaborating with ED physicians increased access to HTN management with a positive impact on BP outcomes in an under-resourced population.

Objectives: We examine the mediation effects of prenatal stress on the associations between intimate partner violence (IPV) experience and the most common forms of substance use (i.e., cigarette smoking, alcohol drinking, and marijuana use) among pregnant Black women.Design: Cross‐sectional.Sample: Black women (N = 203) from metropolitan Detroit, Michigan and Columbus, Ohio, were recruited between 8 and 29 weeks of gestation.Measurements: Women were asked about IPV experience during 12 months prior to the start of the pregnancy, perceived stress during pregnancy, and substance use during pregnancy.Results: Intimate partner violence prior to pregnancy was positively associated with cigarette smoking and marijuana use but not with alcohol use during pregnancy. IPV prior to pregnancy was also positively associated with higher levels of perceived stress during pregnancy after controlling for covariates. Path analysis indicated that IPV had an indirect effect on marijuana use through perceived stress (standardized indirect effect = 0.026, SE = 0.020, 95% CI = 0.005–0.064, p =.017).Conclusions: Perceived stress during pregnancy partially mediated the association between previous experience of IPV and marijuana use among pregnant Black women. Interventions are needed to reduce IPV that would lower stress during pregnancy and consequently substance abuse to improve pregnancy outcomes and maternal and newborn health.

Objective: This study examined whether cigarette smoking mediated the association of racial discrimination with depressive symptoms among pregnant Black women.Design: Cross‐sectional.Sample: Two hundred Black women at 8–29 weeks gestation.Measurements: Women completed questionnaires including the Experiences of Discrimination and the Center for Epidemiologic Studies‐Depression (CES‐D) scales, as well as questions about sociodemographic characteristics and cigarette smoking.Results: The mean age of the sample was 26.9 ± 5.7 years and the mean gestational age at data collection was 15.6 ± 5.7 weeks. Approximately 17% of women reported prenatal cigarette smoking; 27% had prenatal CES‐D scores ≥23, which have been correlated with depression diagnoses; and 59% reported ever (lifetime) experiencing discrimination in at least one situation (e.g., at work). Path analysis results indicated that the standardized indirect effect of experiences of racial discrimination on CES‐D scores through prenatal smoking was statistically significant (standardized indirect effect = 0.03; 95% CI: 0.001, 0.094; p = .042).Conclusion: Cigarette smoking during pregnancy partially mediated the association between lifetime experiences of racial discrimination and prenatal depressive symptoms among pregnant Black women. Smoking cessation programs should focus on identifying and treating depressive symptoms among pregnant Black women.

Introducing patient safety and quality improvement science to medical students is integral to improving healthcare. However, developing and implementing a patient safety curriculum can be challenging in a medical school curriculum that is already densely packed. Our aim was to develop and evaluate the impact of a workshop introducing patient safety and quality improvement science to a large class of first-year medical students. As a part of an evolving longitudinal patient safety curriculum, an introductory workshop on patient safety was integrated into an anatomy course. A high impact event (a simulated “retained sponge” discovery during an anatomy dissection lab) was used to introduce medical error. The educational session which followed consisted of a presentation by an interprofessional team utilizing the retained sponge as example of an error. Use of safety tools was introduced and quality improvement science was discussed using the evolution of methods to decrease retained foreign objects during surgery. A patient’s story told by a close family member about the personal impact of medical errors was presented. Students then participated in an interactive breakout activity and completed a module on safety. The impact of the workshop was assessed through pre- and post- session tests. Quantitative and qualitative evaluation reflected a positive effect of the session in improving students’ safety knowledge and attitudes. Students’ mean total knowledge improved from 7.58 to 8.98 (p = 0.000). Mean total attitudes score improved from 47.73 to 50.56 (p = 0.000). Students’ comments after the workshop reflected increased awareness and appreciation of the importance of addressing medical errors. A workshop introducing patient safety and quality improvement to first year medical students improved knowledge and attitudes regarding safety and increased awareness of the importance of addressing medical errors in their future careers. Integrating patient safety education into an existing foundational science course is a model for teaching patient safety at other medical schools.
