Inequities in Inpatient Pediatric Patient Safety Events by Category

Few studies have analyzed potential inequities in both pediatric patient safety events (PSEs) and adverse events (AEs) - PSEs leading to harm - nor in PSEs by event type. We sought to examine potential inequities in rates of pediatric PSEs overall, by severity, and by category based on race and ethnicity, insurance payor, and language as measured using voluntary incident reports (IRs).

We conducted a retrospective cohort study of pediatric hospitalizations between January 19, 2012 through December 31, 2019 at a US urban, tertiary care children's hospital. Analyzing 85 458 hospitalizations, we compared PSEs overall, by severity, and by event category by race and ethnicity, insurance payor, and language using incident rate ratios (IRRs).

In models controlling for covariates, we found that hospitalizations of Latinx (IRR 1.17, 95% confidence interval [CI] 1.07-1.29), non-Latinx Black/African American (IRR 1.17, 95% CI 1.01-1.34), publicly insured (IRR 1.10, 95% CI 1.02-1.20), and nonprivately/nonpublicly insured (IRR 1.12, 95% CI 1.02-1.23) children had higher rates of PSEs compared with reference groups, but the association between language and PSEs was not significant. There were similar patterns among AEs, although only the association between hospitalizations of Latinx patients and AEs was significant. Medication, fluid, or blood and lines or tubes PSEs drove many inequities.

We found inequities in PSEs as recorded by IRs, suggesting differences in care related to race, ethnicity, and payor. Limitations include analysis of a single center, that event categories are unique to the institution analyzed, and the voluntary nature of IRs.
