Agency for Healthcare Research and Quality pediatric indicators as a quality metric for surgery in children: do they predict adverse outcomes?

Background/PurposeThe pediatric quality indicators (PDIs) were developed by the Agency for Healthcare Research and Quality to compare patient safety and quality of pediatric care. These are being considered for mandatory reporting as well as pay-for-performance efforts. The present study evaluates the PDIs' predictive value for surgical outcomes in children.MethodsA cross-sectional study was performed using nationwide inpatient data from 1988 to 2007. Patients younger than 18 years with an inpatient surgical procedure were included and evaluated for 10 PDIs. Odds ratios for mortality, increase in length of stay, and total charges were calculated using multivariate regression adjusting for age, sex, race, region, hospital type, and comorbidities.ResultsA total of 1,964,456 pediatric discharges were included. Mortality rates were 5.4% for patients with at least 1 PDI and 0.6% for those with none. Multivariate analysis showed that occurrence of any PDI was associated with a 20% increased risk of mortality. The PDIs were associated with an increased length of stay and total hospital charges.ConclusionThe present study shows that PDIs are associated with increased mortality risk as well as increased hospital stay and total hospital charges. This provides positive evidence for the utility of these indicators as metrics for quality and patient safety.
