WHAT'S KNOWN ON THIS SUBJECT: Readmissions have been identified as a priority area for pediatric inpatient quality measurement nationally. However, it is unknown whether readmission rates vary meaningfully across hospitals and how many hospitals would be identified as high-or low-performers.
WHAT THIS STUDY ADDS:Only a few hospitals that care for children are high-or low-performers when their conditionspecific revisit rates are compared with average rates across hospitals. This limits the usefulness of condition-specific readmission or revisit measures in pediatric quality measurement. abstract OBJECTIVE: To assess variation among hospitals on pediatric readmission and revisit rates and to determine the number of high-and low-performing hospitals.
METHODS:In a retrospective analysis using the State Inpatient and Emergency Department Databases from the Healthcare Cost and Utilization Project with revisit linkages available, we identified pediatric (ages 1-20 years) visits with 1 of 7 common inpatient pediatric conditions (asthma, dehydration, pneumonia, appendicitis, skin infections, mood disorders, and epilepsy). For each condition, we calculated rates of all-cause readmissions and rates of revisits (readmission or presentation to the emergency department) within 30 and 60 days of discharge. We used mixed logistic models to estimate hospital-level riskstandardized 30-day revisit rates and to identify hospitals that had performance statistically different from the group mean.RESULTS: Thirty-day readmission rates were low (,10.0%) for all conditions. Thirty-day rates of revisit to the inpatient or emergency department setting ranged from 6.2% (appendicitis) to 11.0% (mood disorders). Study hospitals (n = 958) had low condition-specific visit volumes (37.0%-82.8% of hospitals had ,25 visits). The only condition with .1% of hospitals labeled as different from the mean on 30-day risk-standardized revisit rates was mood disorders (4.2% of hospitals [n = 15], range of hospital performance 6.3%-15.9%).
CONCLUSIONS:We found that when comparing hospitals' performances to the average, few hospitals that care for children are identified as high-or low-performers for revisits, even for common pediatric diagnoses, likely due to low hospital volumes. This limits the usefulness of condition-specific readmission or revisit measures in pediatric quality measurement. Pediatrics 2013;132:429-436
