Background: In the United States, Black maternal mortality is 2–4 × higher than that of White maternal mortality, with differences also present in severe maternal morbidity and other measures. However, limited research has comprehensively studied multilevel social determinants of health, and their confounding and effect modification on obstetrical outcomes. Materials and Methods: We performed a retrospective multistate analysis of adult inpatient delivery hospitalizations (Florida, Kentucky, Maryland, New Jersey, New York, North Carolina, and Washington) between 2007 and 2020. Multilevel multivariable models were used to test the confounder-adjusted association for race/ethnicity and the binary outcomes (1) in-hospital mortality or maternal end-organ injury and (2) in-hospital mortality only. Stratified analyses were performed to test effect modification. Results: The confounder-adjusted odds ratio showed that Black (1.33, 95% confidence interval [CI]: 1.30–1.36) and Hispanic (1.14, 95% CI: 1.11–1.18) as compared with White patients were more likely to die in-hospital or experience maternal end-organ injury. For Black and Hispanic patients, stratified analysis showed that findings remained significant in almost all homogeneous strata. After statistical adjustment, Black as compared with White patients were more likely to die in-hospital (1.49, 95% CI: 1.21–1.82). Conclusions: Black and Hispanic patients had higher adjusted odds of in-patient mortality and end-organ damage after birth than White patients. Race and ethnicity serve as strong predictors of health care inequality, and differences in outcomes may reflect broader structural racism and individual implicit bias. Proposed solutions require immense and multifaceted active efforts to restructure how obstetrical care is provided on the societal, hospital, and patient level. [ABSTRACT FROM AUTHOR]

Background and Aim: Safety-net hospitals (SNHs) serve high proportions of uninsured and Medicaid patients. Data conflict as to the impact of hospital safety-net status on perioperative complications. Our goal was to assess the effect of hospital safety-net burden on mortality and readmission following coronary artery bypass graft (CABG) surgery.Methods: A retrospective analysis was performed using five State Inpatient Databases (2007-2014) for isolated CABG surgery. High, medium, and low burden hospitals were those with the highest, middle, and lowest tertiles of uninsured and Medicaid admissions, respectively. We compared patient demographics and hospital characteristics by safety-net status. Multivariable logistic regression models assessed adjusted odds of in-hospital mortality and 30- and 90-day readmission.Results: About 304 080 patients were included in our analysis. On univariate analysis, high burden hospitals had higher inpatient mortality (2.06% vs 1.71%; P < .001) and 30 day- (16.3% vs 15.3%; P < .001) and 90-day readmission rates (24.6% vs 23.0%; P < .001). On multivariate analysis, high-burden status was not associated with significantly increased adjusted odds of inpatient mortality (OR, 1.047; 95% CI, 0.878-1.249), or readmission at 30 (OR, 1.035; 95% CI, 0.958-1.118) or 90 days (OR, 1.040; 95% CI, 0.968-1.117).Conclusion: SNHs do not have worse mortality and readmission outcomes following CABG, after adjusting for patient and hospital characteristics. These findings are reassuring regarding the quality of cardiac surgery care provided to underinsured patient groups. More research is needed to further elucidate trends in outcomes.

Study Objectives: To investigate postoperative outcomes following total hip arthroplasty (THA) in patients with obstructive sleep apnea (OSA). To evaluate trends in the use of regional anesthesia (RA) versus general anesthesia (GA) following the publication of practical guidelines. To compare postoperative outcomes according to anesthesia type.Design: Retrospective analysis.Setting: Operating room.Patients: 349,008 patients who underwent elective THA in Florida, New York, Maryland, and Kentucky between 2007 and 2014 were extracted from the State Inpatient Databases (SID), Healthcare Cost and Utilization Project, including 18,063 patients with OSA (5.2%).Interventions: No intervention.Measurements: The effect of OSA on postoperative outcomes was investigated using bivariate analysis and multivariable logistic regression models. Outcomes studied included in-hospital mortality, postoperative complications, length of stay (LOS), and post-discharge readmissions. In a population from New York only, (n = 105,838 with 5306 patients with OSA [5.0%]), we investigated the outcomes in the OSA population according to the anesthesia type. Analysis was performed overall and for each individual year.Main Results: The OSA prevalence increased from 1.7% in 2007 to 7.1% in 2014. In multivariable analysis, there was no effect of OSA on in-hospital mortality (aOR:0.57; 0.31-1.04). Postoperative complications, LOS, and readmission rates were all higher in patients with OSA. In patients with OSA receiving GA than those receiving RA, we found a higher rate of complications overall and pulmonary complications specifically in men and higher rate of 90-day readmission in women. Over the study period, the rate of GA use in patients with OSA increased.Conclusions: The OSA prevalence in patients undergoing THA increased fourfold over the study period. OSA was associated with increased overall postoperative complications, LOS, and readmission, but not with in-hospital mortality. Despite the publication of guidelines favoring RA over GA, the use of GA increased over the study period. [ABSTRACT FROM AUTHOR]
