BackgroundPreviously few means existed to broadly examine variability across conditions/practices within or between hospitals for common pediatric conditions.ObjectiveOur objective was to develop a novel empiric measure of variation in care and test its association with patient-centered outcomes.DesignsWe conducted a retrospective cohort study of children hospitalized from January 2016 to December 2018 using the Pediatric Hospital Information Systems database.Settings And ParticipantsWe included children ages 0-18 years hospitalized with asthma, bronchiolitis, or gastroenteritis.InterventionWe developed a hospital-specific measure of variation in care, the hospital's observed specific standard practice (HOSSP), the most common combination of laboratory studies, imaging, and medications used at each hospital.Main Outcome And MeasuresThe outcomes were standardized costs, length of stay (LOS), and 7-day all-cause readmissions.ResultsAmong 133,392 hospitalizations from 41 hospitals (asthma = 50,382, bronchiolitis = 54,745, and gastroenteritis = 28,265), there was significant variation in overall HOSSP adherence across hospitals for these conditions (asthma: 3.5%-47.4% [p < .001], bronchiolitis: 2.5%-19.8% [p < .001], gastroenteritis: 1.6%-11.6% [p < .001]). The majority of HOSSP variation was driven by differences in medication prescribing for asthma and bronchiolitis and laboratory ordering for gastroenteritis. For all three conditions, greater HOSSP adherence was associated with significantly lower hospital costs (asthma: p = .04, bronchiolitis: p < .001, acute gastroenteritis: p = .01), without increases in LOS or 7-day all cause readmissions.ConclusionWe found substantial variation in the components and adherence to HOSSP. Hospitals with greater HOSSP adherence had lower costs for these conditions. This suggests hospitals can use data around laboratory, imaging, and medication prescribing practices to drive standardization of care, reduce unnecessary testing and treatment, determine best practices, and reduce costs.© 2022 Society of Hospital Medicine.
