Development and Use of a Calculator to Measure Pediatric Low-Value Care Delivered in US Children's Hospitals.

Importance: The scope of low-value care in children's hospitals is poorly understood. Objective: To develop and apply a calculator of hospital-based pediatric low-value care to estimate prevalence and cost of low-value services. Design, Setting, and Participants: This cross-sectional study developed and applied a calculator of hospital-based pediatric low-value care to estimate the prevalence and cost of low-value services among 1 011 950 encounters reported in 49 US children's hospitals contributing to the Pediatric Health Information System (PHIS) database. To develop the calculator, a multidisciplinary stakeholder group searched existing pediatric low-value care measures and used an iterative process to identify and operationalize relevant hospital-based measures in the PHIS database. Children with an eligible encounter in 2019 were included in the calculator-applied analysis. Two cohorts were analyzed: an emergency department cohort (with encounters resulting in emergency department discharge) and a hospitalized cohort. Exposures: Eligible condition-specific hospital encounters. Main Outcomes and Measures: The proportion and volume of encounters in which low-value services were delivered and their associated standardized costs. Measures were ranked by those outcomes. Results: There were 1 011 950 encounters eligible for 1 or more of 30 calculator-included measures in 2019; encounters were incurred by 816 098 unique patients with a median age of 3 years (IQR, 1-8 years). In the emergency department cohort, low-value services delivered in the greatest percentage of encounters were Group A streptococcal testing among children younger than 3 years with pharyngitis (3679 of 9785 [37.6%]), computed tomography scan for minor head injury (7541 of 42 602 [17.7%]), and bronchodilators for treatment of bronchiolitis (8899 of 55 616 [16.0%]). In the hospitalized cohort, low-value care was most prevalent for broad-spectrum antibiotics in the treatment of community-acquired pneumonia (3406 of 5658 [60.2%]), acid suppression therapy for infants with esophageal reflux (3814 of 7507 of [50.8%]), and blood cultures for uncomplicated community-acquired pneumonia (2277 of 5823 [39.1%]). Measured low-value services generated nearly $17 million in total standardized cost. The costliest services in the emergency department cohort were computed tomography scan for abdominal pain (approximately $1.8 million) and minor head injury (approximately $1.5 million) and chest radiography for asthma (approximately $1.1 million). The costliest services in the hospitalized cohort were receipt of 2 or more concurrent antipsychotics (approximately $2.4 million), and chest radiography for bronchiolitis ($801 680) and asthma ($625 866). Conclusions and Relevance: This cross-sectional analysis found that low-value care for some pediatric services was prevalent and costly. Measuring receipt of low-value services across conditions informs prioritization of deimplementation efforts. Continued use of this calculator may establish trends in low-value care delivery.

Impact of the Choosing Wisely® Campaign Recommendations for Hospitalized Children on Clinical Practice: Trends from 2008 to 2017.

BACKGROUND: The Choosing Wisely® Campaign (CWC) was launched in 2012. Five recommendations to reduce the use of "low-value" services in hospitalized children were published in 2013. OBJECTIVES: The aim of this study was to estimate the frequency and trends of utilization of these services in tertiary children's hospitals five years before and after the publication of the recommendations. METHODS: We conducted a retrospective, longitudinal analysis of hospitalizations to 36 children's hospitals from 2008 to 2017. The "low-value" services included (1) chest radiograph (CXR) for asthma, (2) CXR for bronchiolitis, (3) relievers for bronchiolitis, (4) systemic steroids for lower respiratory tract infection (LRTI), and (5) acid suppressor therapy for uncomplicated gastroesophageal reflux (GER). We estimated the annual percentages of the use of these services after risk adjustment, followed by an interrupted time series (ITS) analysis to compare trends before and after the publication of the recommendations. RESULTS: The absolute decreases in utilization were 36.6% in relievers and 31.5% in CXR for bronchiolitis, 24.1% in acid suppressors for GER, 20.8% in CXR for asthma, and 2.9% in steroids for LRTI. Trend analysis showed that one "low-value" service declined significantly immediately (use of CXR for asthma), and another decreased significantly over time (relievers for bronchiolitis) after the CWC. CONCLUSIONS: There was some decrease in the utilization of "low-value" services from 2008 to 2017. Limited changes in trends occurred after the publication of the recommendations. These findings suggest a limited impact of the CWC on clinical practice in these areas. Additional interventions are required for a more effective dissemination of the CWC recommendations for hospitalized children.
