IMPORTANCE A high cesarean delivery rate in US hospitals indicates the potential overuse of this procedure; however, underlying causes of the excessive use of cesarean procedures in the US have not been fully understood. OBJECTIVE To investigate the association between the probability of cesarean delivery at the patient-level and profit per procedure from cesarean deliveries. DESIGN, SETTING, AND PARTICIPANTS This observational, cross-sectional study used a nationally representative sample of hospital discharge data from women at low risk for cesarean birth who delivered newborns between 2010 and 2014 in the US. Data were gathered from the Nationwide Readmissions Database from the Healthcare Cost and Utilization Project, compiled by the Agency for Healthcare Research and Quality. Data cleaning and analyses were conducted between August 2019 and May 2020. EXPOSURES Hospital-level median value of profits from cesarean deliveries, defined as the difference between the charge and the cost for cesarean delivery calculated for each hospital. MAIN OUTCOMES AND MEASURES Our primary outcome was the individual-level probability of undergoing a cesarean delivery. We examined the association with the hospital-level median value of profits per procedure for cesarean delivery (defined as the difference between the charge and the cost for cesarean delivery) using hierarchical regression models adjusted for patient and hospital characteristics and year-fixed effects. RESULTS A total of 13 215 853 deliveries were included in our analyses (mean [SE] age, 27.4 [0] years), of which 2 202 632 (16.7%) were cesarean deliveries. After adjusting for potential confounders, pregnant women were more likely to have a cesarean birth when they delivered at hospitals with higher profits per procedure from cesarean deliveries. Women cared for at hospitals with the highest (adjusted odds ratio, 1.08; 95% CI, 1.02-1.14; P = .005) and second-highest profit quartiles (adjusted odds ratio, 1.07; 95% CI, 1.02-1.13; P = .007) had higher probabilities of a cesarean delivery compared with those cared for at hospitals in the lowest profit quartile. CONCLUSIONS AND RELEVANCE In this cross-sectional study of US nationally representative hospital discharge data, hospitals with higher profits per cesarean procedure were associated with an increased probability of delivering newborns through cesarean birth. These findings highlight the potential influence financial incentives play in determining a high cesarean delivery rate in the US.
Objective Regionalization directs patients to high‐volume hospitals for specialized care. We investigated regionalization trends and outcomes in pediatric cardiac surgery. Data Sources/Study Setting Statewide inpatient data from eleven states between 2000 and 2012. Study Design Mortality, length of stay (LOS), and cost were assessed using multivariable hierarchical regression with state and year fixed effects. Primary predictor was hospital case‐volume, categorized into low‐, medium‐, and high‐volume tertiles. Data Collection/Extraction Methods We used Risk Adjustment for Congenital Heart Surgery‐1 (RACHS‐1) to select pediatric cardiac surgery discharges. Principal Findings In total, 2841 (8.5 percent), 8348 (25.1 percent), and 22 099 (66.4 percent) patients underwent heart surgeries in low‐, medium‐, and high‐volume hospitals. Mortality decreased over time, but remained higher in low‐ and medium‐volume hospitals. High‐volume hospitals had lower odds of mortality and cost than low‐volume hospitals (odds ratio [OR] 0.59, P < 0.01, and relative risk [RR] 0.91, P < 0.01, respectively). LOS was longer for high‐ and medium‐volume hospitals, compared to low‐volume hospitals (high‐volume: RR 1.18, P < 0.01; medium‐volume: RR 1.05, P < 0.01). Conclusions Regionalization reduced mortality and cost, indicating fewer complications, but paradoxically increased LOS. Further research is needed to explore the full impact on health care utilization.
BACKGROUND AND OBJECTIVES: Asthma is widely prevalent among US children, particularly in homeless children, who often lack proper medication storage or the ability to avoid environmental triggers. In this study, we assess asthma-attributed health care use among homeless youth. We hypothesize that asthma hospitalization rates, symptom severity, and admission through the emergency department (ED) will be higher among homeless youth compared with nonhomeless youth. METHODS: This secondary data analysis identified homeless and nonhomeless pediatric patients (,18 years old) with a primary diagnosis of asthma from New York statewide inpatient databases between 2009 and 2014. Hospitalization rate, readmission rate, admission through the ED, ventilation use, ICU admittance, hospitalization cost, and length of stay were measured. RESULTS: We identified 71 837 asthma hospitalizations, yielding 73.8 and 2.3 hospitalizations per 1000 homeless and nonhomeless children, respectively. Hospitalization rates varied by nonhomeless income quartile, with low-income children experiencing higher rates (5.4) of hospitalization. Readmissions accounted for 16.0% of homeless and 12.5% of nonhomeless hospitalizations. Compared with nonhomeless patients, homeless patients were more likely to be admitted from the ED (odds ratio 1.96; 95% confidence interval: 1.82-2.12; P , .01), and among patients .5 years old, homeless patients were more likely to receive ventilation (odds ratio 1.45; 95% confidence interval: 1.01-2.09; P 5 .04). No significant differences were observed in ICU admittance, cost, or length of stay. CONCLUSIONS: Homeless youth experience an asthma hospitalization rate 31 times higher than nonhomeless youth, with higher rates of readmission. Homeless youth live under uniquely challenging circumstances. Tailored asthma control strategies and educational intervention could greatly reduce hospitalizations. WHAT'S KNOWN ON THIS SUBJECT: Asthma is widely prevalent among US children, particularly in homeless children, who often lack proper medication storage or ability to avoid environmental triggers. Poor treatment adherence and follow-up have been reported, making homeless children susceptible to attacks. WHAT THIS STUDY ADDS: Because of high prevalence and attack susceptibility, use of health care by homeless patients with asthma could be high. However, no prior studies have quantified these levels. This study offers new insight on asthma-attributed health care use among homeless and nonhomeless youth.
