Two-Year Utilization and Expenditures for Children After a Firearm Injury.

INTRODUCTION: Firearm injuries are a leading cause of morbidity among children, but data on healthcare utilization and expenditures after injury are limited. This study sought to analyze healthcare encounters and expenditures for 2 years after a nonfatal firearm injury. METHODS: A retrospective cohort study was conducted between 2020 and 2022 of children aged 0-18 years with International Classification of Diseases, Ninth Revision/ICD-10 diagnosis codes for firearm injury from 2010 to 2016 in the Medicaid MarketScan claims database. Outcomes included the difference in healthcare encounters and expenditures, including mental health. Descriptive statistics characterized patient demographics and healthcare utilization. Changes in health expenditures were evaluated with Wilcoxon sign rank tests. RESULTS: Among 911 children, there were 12,757 total healthcare encounters in the year before the index firearm injury, 15,548 1 encounters in the year after (p<0.001), and 10,228 total encounters in the second year (p<0.001). Concomitantly, there was an overall increase of $14.4 million in health expenditures ($11,415 per patient) 1 year after (p<0.001) and a $0.8 million decrease 2 years after the firearm injury (p=0.001). The children with low previous expenditures (majority of sample) had sustained increases throughout the second year after injury. There was a 31% and 37% absolute decrease in mental health utilization and expenditures, respectively, among children 2 years after the firearm injury. CONCLUSIONS: Children who experience nonfatal firearm injury have an increased number of healthcare encounters and healthcare expenditures in the year after firearm injury, which is not sustained for a second year. Mental health utilization and expenditures remain decreased up to 2 years after a firearm injury. More longitudinal research on the morbidity associated with nonfatal firearm injuries is needed.

Hospital's observed specific standard practice: A novel measure of variation in care for common inpatient pediatric conditions.

BACKGROUND: Previously few means existed to broadly examine variability across conditions/practices within or between hospitals for common pediatric conditions. OBJECTIVE: Our objective was to develop a novel empiric measure of variation in care and test its association with patient-centered outcomes. DESIGNS: We conducted a retrospective cohort study of children hospitalized from January 2016 to December 2018 using the Pediatric Hospital Information Systems database. SETTINGS AND PARTICIPANTS: We included children ages 0-18 years hospitalized with asthma, bronchiolitis, or gastroenteritis. INTERVENTION: We 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 MEASURES: The outcomes were standardized costs, length of stay (LOS), and 7-day all-cause readmissions. RESULTS: Among 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. CONCLUSION: We 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.

Epidemiology and Risk Factors for Hemodialysis Access-Associated Infections in Children: A Prospective Cohort Study From the SCOPE Collaborative.

RATIONALE & OBJECTIVE: Infections cause significant morbidity and mortality for children receiving maintenance hemodialysis (HD). The Standardizing Care to Improve Outcomes in Pediatric End-Stage Kidney Disease (SCOPE) Collaborative is a quality-improvement initiative aimed at reducing dialysis-associated infections by implementing standardized care practices. This study describes patient-level risk factors for catheter-associated bloodstream infections (CA-BSIs) and examines the association between dialysis center-level compliance with standardized practices and risk of CA-BSI. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Children enrolled in SCOPE between June 2013 and July 2019. EXPOSURES: Data were collected on patient characteristics and center-level compliance with HD catheter care practices across the study period. Centers were categorized as consistent, dynamic (improved compliance over the study period), or inconsistent performers based on frequency of compliance audit submission and changes in compliance with HD care practices over time. OUTCOME: CA-BSIs. ANALYTICAL APPROACH: Generalized linear mixed models were used to evaluate (1) patient-level risk factors for CA-BSI and (2) associations between change in center-level compliance and CA-BSIs. RESULTS: The cohort included 1,277 children from 35 pediatric dialysis centers; 1,018 (79.7%) had a catheter and 259 (20.3%) had an arteriovenous fistula or graft. Among children with a catheter, mupirocin use at the catheter exit site was associated with an increased rate of CA-BSIs (rate ratio [RR], 4.45; P = 0.004); the use of no antibiotic agent at the catheter exit site was a risk factor of borderline statistical significance (RR, 1.79; P = 0.05). Overall median compliance with HD catheter care practices was 87.5% (IQR, 77.3%-94.0%). Dynamic performing centers showed a significant decrease in CA-BSI rates over time (from 2.71 to 0.71 per 100 patient-months; RR, 0.98; P < 0.001), whereas no significant change in CA-BSI rates was detected among consistent or inconsistent performers. LIMITATIONS: Lack of data on adherence to HD care practices on the individual patient level. CONCLUSIONS: Improvement in compliance with standardized HD care practices over time may lead to a reduction in dialysis-associated infections.

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.

A comparison of the buttonhole and rope-ladder AVF cannulation techniques and infection rates within the SCOPE collaborative.

BACKGROUND: Studies regarding hemodialysis (HD) arteriovenous fistula (AVF) cannulation in adults indicate a higher risk of infection with the buttonhole (BH) technique compared to the rope-ladder (RL) technique. Pediatric data on this issue is sparse. METHODS: We compared infection rates within the Standardizing Care to Improve Outcomes in Pediatric End stage kidney disease (SCOPE) centers performing BH cannulation versus RL cannulation of AVF. Generalized linear mixed modeling was used to assess differences in access-related blood stream infection (BSI) and access site infection (ASI) rates between the centers. RESULTS: Data was available from 211 AVF enrollments among 210 children. There were 61 AVF enrollments at 6 BH centers and 150 enrollments at 13 RL centers. Demographics were similar between the two groups. There were 12 total infections in 3383 patient months. BH centers had 3 infections (0 BSI, 3 ASI) and RL centers had 9 infections (5 BSI, 3 ASI). Mean [95% confidence interval] infection rates per 1000 patient months were not different between BH and RL centers (BH: 3.1 [0.6,15.6], RL: 3.2 [1.3,9.4], p = 0.947). A survey was also completed by the BH centers to describe their BH practices. The BH procedure at the majority of sites was characterized by a small patient/nurse ratio and strict antiseptic protocols. CONCLUSIONS: This data provides evidence of a low BSI rate associated with BH cannulation in pediatric HD patients. Further studies are needed to better delineate the differences in the pediatric and adult experience with the BH cannulation technique.

Continued reduction in peritonitis rates in pediatric dialysis centers: results of the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Collaborative.

BACKGROUND: In its first 3 years, the Standardizing Care to Improve Outcomes in Pediatric End Stage Renal Disease (SCOPE) Collaborative demonstrated a statistically significant increase in the likelihood of compliance with a standardized follow-up care bundle and a significant reduction in peritonitis. We sought to determine if compliance with care bundles and low peritonitis rates could be sustained in centers continuously participating for 84 months. METHODS: Centers that participated from collaborative launch through the 84-month study period and provided pre-launch peritonitis rates were included. Children on maintenance peritoneal dialysis were eligible for enrollment. Changes in bundle compliance were assessed using a logistic regression model or a generalized linear mixed model (GLMM). Changes in average annualized peritonitis rates over time were modeled using GLMMs. RESULTS: Nineteen centers contributed 1055 patients with 1268 catheters and 17,247 follow-up encounters. The likelihood of follow-up compliance increased significantly over the study period (OR 1.05 95% confidence interval (CI) 1.03, 1.07; p < 0.001). Centers achieved ≥ 80% follow-up bundle compliance by 28 months and maintained a mean compliance of 84% between 28 and 84 months post-launch. Average monthly peritonitis rates decreased from 0.53 (95% CI 0.37, 0.70) infections per patient-year pre-launch to 0.30 (95% CI 0.23, 0.43) at 84 months post-launch, p < 0.001. CONCLUSIONS: Centers participating in the SCOPE Collaborative for 84 months achieved and maintained a high level of compliance with a standardized follow-up care bundle and demonstrated a significant and continued reduction in average monthly peritonitis rates.
