Setting a universal standard: Should we benchmark quality outcomes for pediatric anesthesia care?

Anesthesiology is a medical specialty well known for its work in patient safety, allowing the field to show a dramatic decrease in perioperative morbidity and mortality in both adults and children since the 1950s. Currently, anesthesia-related mortality is close to zero in healthy children, with deaths occurring primarily in children ASA physical status ≥4. Survival during anesthesia today represents the expectation and standard of care, rather than a marker of quality. Several programs and organizations have created measures to assess safety in pediatric anesthesia-yet none are universally accepted as safety metrics or bundled to evaluate specific aspects of care. In addition, collection of this nonstandardized data in individual centers requires a significant investment of resources and personnel limiting access to only large, "resource-rich" institutions. In this perspective paper, we provide an overview of the efforts made to enhance quality of care across medical specialties with a specific emphasis on pediatric anesthesiology. We discuss the need for standardization of metrics to establish targets and benchmarks for the delivery of high-quality care to children and adolescents mainly in North America. The time has come to move beyond mortality and establish universally accepted minimum outcome standards in pediatric anesthesia. We believe this will ultimately improve confidence in the quality of pediatric anesthesia care offered to children, no matter where they are receiving that care.

Association of Clinical Guidelines and Decision Support with Computed Tomography Use in Pediatric Mild Traumatic Brain Injury.

OBJECTIVE: To examine whether the presence of clinical guidelines and clinical decision support (CDS) for mild traumatic brain injury (mTBI) are associated with lower use of head computed tomography (CT). STUDY DESIGN: We conducted a cross-sectional study of 45 pediatric emergency departments (EDs) in the Pediatric Hospital Information System from 2015 through 2019. We included children discharged with mTBI and surveyed ED clinical directors to ascertain the presence and implementation year of clinical guidelines and CDS. The association of clinical guidelines and CDS with CT use was assessed, adjusting for relevant confounders. As secondary outcomes, we evaluated ED length of stay and rates of 3-day ED revisits and admissions after revisits. RESULTS: There were 216 789 children discharged with mTBI, and CT was performed during 20.3% (44 114/216 789) of ED visits. Adjusted hospital-specific CT rates ranged from 11.8% to 34.7% (median 20.5%, IQR 17.3%, 24.3%). Of the 45 EDs, 17 (37.8%) had a clinical guideline, 9 (20.0%) had CDS, and 19 (42.2%) had neither. Compared with EDs with neither a clinical guideline nor CDS, visits to EDs with CDS (aOR 0.52 [0.47, 0.58]) or a clinical guideline (aOR 0.83 [0.78, 0.89]) had lower odds of including a CT for mTBI. ED length of stay and revisit rates did not differ based on the presence of a clinical guideline or CDS. CONCLUSIONS: Clinical guidelines for mTBI, and particularly CDS, were associated with lower rates of head CT use without adverse clinical outcomes.

Discharge Prescription Errors After the Implementation of a Prospective Pharmacist Review Process in a Pediatric Emergency Department.

OBJECTIVES: Pediatric emergency department (ED) patients are at an increased risk for experiencing a preventable medication error. Studies show that pharmacists are effective at decreasing medication errors on inpatient orders but there are few studies looking at error reduction on discharge prescriptions. Children's Health implemented a prospective pharmacist verification process on all ED discharge prescriptions. The objective of this study is to identify and describe the prescription errors leaving a pediatric ED after the implementation of this pharmacist review process. METHODS: An electronic medical database was utilized to identify all ED prescriptions between January 1, 2016, and June 30, 2016. A random number generator was used to select 750 prescriptions. Two pharmacists independently performed a chart review assessing prescriptions for errors. A third pharmacist was used to clarify discordant assessments between the 2 pharmacists. Errors were recorded and assessed for severity using the Taylor et al 2005 stratification. The primary objective of this study is to identify the errors leaving the ED. Secondary objectives include: error severity, error subtype, and readmission rates. RESULTS: Forty-one errors were identified from 750 randomly selected prescriptions for a total error rate of 5.5%. The most common subtypes of errors were missing duration (39%) and antimicrobial optimization (24.4%). When using the Taylor et al 2005 scale, no prescriptions were classified as severe or serious. None of the errors led to patient harm.

Effectiveness of Pediatric Asthma Pathways for Hospitalized Children: A Multicenter, National Analysis.

OBJECTIVE: To determine if clinical pathways affect care and outcomes for children hospitalized with asthma using a multicenter study. STUDY DESIGN: This was a retrospective, multicenter cohort study using an administrative database, the Pediatric Health Information System. We evaluated the impact of inpatient pediatric asthma pathways on children age 2-17 years admitted for asthma from 2006 to 2015 in 42 children's hospitals. Date of pathway implementation for each hospital was collected via survey. Using generalized estimating equations with an interrupted time series approach (to account for secular trends), we determined the association of pathway implementation with length of stay (LOS), 30-day readmission, chest radiograph utilization, ipratropium administration >24 hours, and administration of bronchodilators, systemic steroids, and antibiotics. All analyses were risk-adjusted for patient and hospital characteristics. RESULTS: Clinical pathway implementation was associated with an 8.8% decrease in LOS (95% CI 6.7%-10.9%), 3.1% decrease in hospital costs (95% CI 1.9%-4.3%), increased odds of bronchodilator administration (OR 1.53[1.21-1.95]) and decreased odds of antibiotic administration (OR 0.93[0.87-0.99]) (n = 189 331). We found no associations between pathway implementation and systemic steroid administration, ipratropium administration for >24 hours, chest radiograph utilization, or 30-day readmission. CONCLUSIONS: Clinical pathways can decrease LOS, costs, and unnecessary antibiotic use without increasing rates of readmissions, leading to higher value care.

Impact of Discharge Components on Readmission Rates for Children Hospitalized with Asthma.

OBJECTIVES: To describe hospital-based asthma-specific discharge components at children's hospitals and determine the association of these discharge components with pediatric asthma readmission rates. STUDY DESIGN: This is a multicenter retrospective cohort study of pediatric asthma hospitalizations in 2015 at children's hospitals participating in the Pediatric Health Information System. Children ages 5 to 17 years were included. An electronic survey assessing 13 asthma-specific discharge components was sent to quality leaders at all 49 hospitals. Correlations of combinations of asthma-specific discharge components and adjusted readmission rates were calculated. RESULTS: The survey response rate was 92% (45 of 49 hospitals). Thirty-day and 3-month adjusted readmission rates varied across hospitals, ranging from 1.9% to 3.9% for 30-day readmissions and 5.7% to 9.1% for 3-month readmissions. No individual or combination discharge components were associated with lower 30-day adjusted readmission rates. The only single-component significantly associated with a lower rate of readmission at 3 months was having comprehensive content of education (P < .029). Increasing intensity of discharge components in bundles was associated with reduced adjusted 3-month readmission rates, but this did not reach statistical significance. This was seen in a 2-discharge component bundle including content of education and communication with the primary medical doctor, as well as a 3-discharge component bundle, which included content of education, medications in-hand, and home-based environmental mitigation. CONCLUSIONS: Children's hospitals demonstrate a range of asthma-specific discharge components. Although we found no significant associations for specific hospital-level discharge components and asthma readmission rates at 30 days, certain combinations of discharge components may support hospitals to reduce healthcare utilization at 3 months.

Postacute Care after Pediatric Hospitalizations for a Primary Mental Health Condition.

OBJECTIVES: To determine the proportion of US children hospitalized for a primary mental health condition who are discharged to postacute care (PAC); whether PAC discharge is associated with demographic, clinical, and hospital characteristics; and whether PAC use varies by state. STUDY DESIGN: Retrospective cohort study of a nationally representative sample of US acute care hospitalizations for children ages 2-20 years with a primary mental health diagnosis, using the 2009 and 2012 Kids' Inpatient Databases. Discharge to PAC was used as a proxy for transfer to an inpatient mental health facility. We derived adjusted logistic regression models to assess the association of patient and hospital characteristics with discharge to PAC. RESULTS: In 2012, 14.7% of hospitalized children (n = 248 359) had a primary mental health diagnosis. Among these, 72% (n = 178 214) had bipolar disorder, depression, or psychosis, of whom 4.9% (n = 8696) were discharged to PAC. The strongest predictors of PAC discharge were homicidal ideation (aOR, 24.9; 96% CI, 4.1-150.4), suicide and self-injury (aOR, 15.1; 95% CI, 11.7-19.4), and substance abuse-related medical illness (aOR, 5.0; 95% CI, 4.5-5.6). PAC use varied widely by state, ranging from 2.2% to 36.3%. CONCLUSIONS: The majority of children hospitalized primarily for a mood disorder or psychosis were not discharged to PAC, and safety-related conditions were the primary drivers of the relatively few PAC discharges. There was substantial state-to-state variation. Target areas for quality improvement include improving access to PAC for children hospitalized for mood disorders or psychosis and equitable allocation of appropriate PAC resources across states.

Rising utilization of inpatient pediatric asthma pathways.

INTRODUCTION: Clinical pathways are detailed care plans that operationalize evidence-based guidelines into an accessible format for health providers. Their goal is to link evidence to practice to optimize patient outcomes and delivery efficiency. It is unknown to what extent inpatient pediatric asthma pathways are being utilized nationally. OBJECTIVES: (1) Describe inpatient pediatric asthma pathway design and implementation across a large hospital network. (2) Compare characteristics of hospitals with and without pathways. METHODS: We conducted a descriptive, cross-sectional, survey study of hospitals in the Pediatric Research in Inpatient Settings Network (75% children's hospitals, 25% community hospitals). Our survey determined if each hospital used a pathway and pathway characteristics (e.g. pathway elements, implementation methods). Hospitals with and without pathways were compared using Chi-square tests (categorical variables) and Student's t-tests (continuous variables). RESULTS: Surveys were distributed to 3-5 potential participants from each hospital and 302 (74%) participants responded, representing 86% (106/123) of surveyed hospitals. From 2005-2015, the proportion of hospitals utilizing inpatient asthma pathways increased from 27% to 86%. We found variation in pathway elements, implementation strategies, electronic medical record integration, and compliance monitoring across hospitals. Hospitals with pathways had larger inpatient pediatric programs [mean 12.1 versus 6.1 full-time equivalents, p = 0.04] and were more commonly free-standing children's hospitals (52% versus 23%, p = 0.05). CONCLUSIONS: From 2005-2015, there was a dramatic rise in implementation of inpatient pediatric asthma pathways. We found variation in many aspects of pathway design and implementation. Future studies should determine optimal implementation strategies to better support hospital-level efforts in improving pediatric asthma care and outcomes.

Racial and Ethnic Differences in Pediatric Readmissions for Common Chronic Conditions.

OBJECTIVE: To compare the timing and magnitude of variation of pediatric readmission rates across race/ethnicity for selected chronic conditions: asthma, diabetes, seizures, migraines, and depression. STUDY DESIGN: Retrospective analysis of hospitalizations at 48 children's hospitals in the 2013 Pediatric Health Information System database for children (ages 0-18 years) admitted for asthma (n = 36 910), seizure (n = 35 361), diabetes (n = 12 468), migraine (n = 5882), and depression (n = 5132). Generalized linear models with a random effect for hospital were used to compare the likelihood of readmission by patients' race/ethnicity, adjusting for severity of illness, age, payer, and medical complexity. Adjusted readmission rates were calculated by week over 1 year. RESULTS: Significant variation in adjusted readmission rates by race/ethnicity existed for conditions aside from depression. Disparities for diabetes and asthma emerged at 3 and 4 weeks, respectively; they remained divergent up to 1 year with the highest 1-year readmission rates in non-Hispanic blacks vs other race/ethnicities (diabetes: 21.7% vs 13.4%, P < .001; asthma: 21.4% vs 14.6%, P < .001). Disparities for migraines and seizure emerged at 6 and 7 weeks, respectively; they remained up to 1 year, with the highest 1-year readmission rates in non-Hispanic whites vs other race/ethnicities (migraine: 17.3% vs 13.6%, P < .001; seizure: 23.9% vs 21.9%, P < .001). CONCLUSIONS: Readmission disparities behave differently across chronic conditions. They emerge more quickly after discharge for children hospitalized with asthma or diabetes than for seizures or migraines. The highest readmission rates were not consistently observed for 1 particular race/ethnicity. Study findings can impact pediatric chronic disease management to improve care for children with these conditions.

Adding Social Determinant Data Changes Children's Hospitals' Readmissions Performance.

OBJECTIVES: To determine whether social determinants of health (SDH) risk adjustment changes hospital-level performance on the 30-day Pediatric All-Condition Readmission (PACR) measure and improves fit and accuracy of discharge-level models. STUDY DESIGN: We performed a retrospective cohort study of all hospital discharges meeting criteria for the PACR from 47 hospitals in the Pediatric Health Information database from January to December 2014. We built four nested regression models by sequentially adding risk adjustment factors as follows: chronic condition indicators (CCIs); PACR patient factors (age and sex); electronic health record-derived SDH (race, ethnicity, payer), and zip code-linked SDH (families below poverty level, vacant housing units, adults without a high school diploma, single-parent households, median household income, unemployment rate). For each model, we measured the change in hospitals' readmission decile-rank and assessed model fit and accuracy. RESULTS: For the 458 686 discharges meeting PACR inclusion criteria, in multivariable models, factors associated with higher discharge-level PACR measure included age <1 year, female sex, 1 of 17 CCIs, higher CCI count, Medicaid insurance, higher median household income, and higher percentage of single-parent households. Adjustment for SDH made small but significant improvements in fit and accuracy of discharge-level PACR models, with larger effect at the hospital level, changing decile-rank for 17 of 47 hospitals. CONCLUSIONS: We found that risk adjustment for SDH changed hospitals' readmissions rate rank order. Hospital-level changes in relative readmissions performance can have considerable financial implications; thus, for pay for performance measures calculated at the hospital level, and for research associated therewith, our findings support the inclusion of SDH variables in risk adjustment.

Delayed Diagnoses in Children with Constipation: Multicenter Retrospective Cohort Study.

OBJECTIVE: The use of abdominal radiographs contributes to increased healthcare costs, radiation exposure, and potentially to misdiagnoses. We evaluated the association between abdominal radiograph performance and emergency department (ED) revisits with important alternate diagnosis among children with constipation. STUDY DESIGN: Retrospective cohort study of children aged <18 years diagnosed with constipation at one of 23 EDs from 2004 to 2015. The primary exposure was abdominal radiograph performance. The primary outcome was a 3-day ED revisit with a clinically important alternate diagnosis. RAND/University of California, Los Angeles methodology was used to define whether the revisit was related to the index visit and due to a clinically important condition other than constipation. Regression analysis was performed to identify exposures independently related to the primary outcome. RESULTS: A total of 65.7% (185 439/282 225) of children with constipation had an index ED visit abdominal radiograph performed. Three-day revisits occurred in 3.7% (10 566/282 225) of children, and 0.28% (784/282 225) returned with a clinically important alternate related diagnosis. Appendicitis was the most common such revisit, accounting for 34.1% of all 3-day clinically important related revisits. Children who had an abdominal radiograph performed were more likely to have a 3-day revisit with a clinically important alternate related diagnosis (0.33% vs 0.17%; difference 0.17%; 95% CI 0.13-0.20). Following adjustment for covariates, abdominal radiograph performance was associated with a 3-day revisit with a clinically important alternate diagnosis (aOR: 1.39; 95% CI 1.15-1.67). Additional characteristics associated with the primary outcome included narcotic (aOR: 2.63) and antiemetic (aOR: 2.35) administration and underlying comorbidities (aOR: 2.52). CONCLUSIONS: Among children diagnosed with constipation, abdominal radiograph performance is associated with an increased risk of a revisit with a clinically important alternate related diagnosis.

Impact of Chronic Conditions on Emergency Department Visits of Children Using Medicaid.

OBJECTIVE: To assess the impact of chronic conditions on children's emergency department (ED) use. STUDY DESIGN: Retrospective analysis of 1 850 027 ED visits in 2010 by 3 250 383 children ages 1-21 years continuously enrolled in Medicaid from 10 states included in the Truven Marketscan Medicaid Database. The main outcome was the annual ED visit rate not resulting in hospitalization per 1000 enrollees. We compared rates by enrollees' characteristics, including type and number of chronic conditions, and medical technology (eg, gastrostomy, tracheostomy), using Poisson regression. To assess chronic conditions, we used the Agency for Healthcare Research and Quality's Chronic Condition Indicator system, assigning chronic conditions with ED visit rates ≥75th percentile as having the "highest" visit rates. RESULTS: The overall annual ED visit rate was 569 per 1000 enrollees. As the number of the children's chronic conditions increased from 0 to ≥3, visit rates increased by 180% (from 376 to 1053 per 1000 enrollees, P < .001). Rates were 174% higher in children assisted with vs without medical technology (1546 vs 565, P < .001). Sickle cell anemia, epilepsy, and asthma were among the chronic conditions associated with the highest ED visit rates (all ≥1003 per 1000 enrollees). CONCLUSIONS: The highest ED visit rates resulting in discharge to home occurred in children with multiple chronic conditions, technology assistance, and specific conditions such as sickle cell anemia. Future studies should assess the preventability of ED visits in these populations and identify opportunities for reducing their ED use.

Socioeconomic Status and Hospitalization Costs for Children with Brain and Spinal Cord Injury.

OBJECTIVE: To determine if household income is associated with hospitalization costs for severe traumatic brain injury (TBI) and spinal cord injury (SCI). STUDY DESIGN: Retrospective cohort study of inpatient, nonrehabilitation hospitalizations at 43 freestanding children's hospitals for patients <19 years old with unintentional severe TBI and SCI from 2009-2012. Standardized cost of care for hospitalizations was modeled using mixed-effects methods, adjusting for age, sex, race/ethnicity, primary payer, presence of chronic medical condition, mechanism of injury, injury severity, distance from residence to hospital, and trauma center level. Main exposure was zip code level median annual household income. RESULTS: There were 1061 patients that met inclusion criteria, 833 with TBI only, 227 with SCI only, and 1 with TBI and SCI. Compared with those with the lowest-income zip codes, patients from the highest-income zip codes were more likely to be older, white (76.7% vs 50.4%), have private insurance (68.9% vs 27.9%), and live closer to the hospital (median distance 26.7 miles vs 81.2 miles). In adjusted models, there was no significant association between zip code level household income and hospitalization costs. CONCLUSIONS: Children hospitalized with unintentional, severe TBI and SCI showed no difference in standardized hospital costs relative to a patient's home zip code level median annual household income. The association between household income and hospitalization costs may vary by primary diagnosis.

Rates and impact of potentially preventable readmissions at children's hospitals.

OBJECTIVE: To assess readmission rates identified by 3M-Potentially Preventable Readmissions software (3M-PPRs) in a national cohort of children's hospitals. STUDY DESIGN: A total of 1 719 617 hospitalizations for 1 531 828 unique patients in 58 children's hospitals from 2009 to 2011 from the Children's Hospital Association Case-Mix Comparative database were examined. Main outcome measures included rates, diagnoses, and costs of potentially preventable readmissions (PPRs) and all-cause readmissions. RESULTS: The 7-, 15-, and 30-day rates by 3M-PPRs were 2.5%, 4.1%, and 6.2%, respectively. Corresponding all-cause readmission rates were 5.0%, 8.7%, and 13.3%. At 30 days, 60.6% of all-cause readmissions were considered nonpreventable by 3M-PPRs, more than one-half of which were related to malignancies. The percentage of readmissions rated as potentially preventable was similar at all 3 time intervals. Readmissions after chemotherapy, acute leukemia, and cystic fibrosis were all considered nonpreventable, and at least 80% of readmissions after index admissions for sickle cell crisis, bronchiolitis, ventricular shunt procedures, asthma, and appendectomy were designated potentially preventable. Total costs for all readmissions were $1.7 billion; PPRs accounted for 27.3% of these costs. The most costly readmissions were associated with ventricular shunt procedures ($26.5 million/year), seizures ($15.5 million/year), and sickle cell crisis ($15.0 million/year). CONCLUSIONS: Rates of PPRs were significantly lower than all-cause readmission rates more than one-half of which were caused by exclusion of malignancies. Annual costs of PPRs, although significant in the aggregate, appear to represent a much smaller cost-savings opportunity for children than for adults. Our study may help guide children's hospitals to focus readmission reduction strategies on areas where the financial vulnerability is greatest based on 3M-PPRs.

Impact of inpatient bronchiolitis clinical practice guideline implementation on testing and treatment.

OBJECTIVE: To determine the association between institutional inpatient clinical practice guidelines (CPGs) for bronchiolitis and the use of diagnostic tests and treatments. STUDY DESIGN: A multicenter retrospective cohort study of infants aged 29 days to 24 months with a discharge diagnosis of bronchiolitis was conducted between July 2011 and June 2012. An electronic survey was sent to quality improvement leaders to determine the presence, duration, and method of CPG implementation at participating hospitals. The Wilcoxon rank-sum test was used to perform bivariate comparisons between hospitals with CPGs and those without CPGs. Multivariable analysis was used to determine associations between CPG characteristics and the use of tests and treatments; analyses were clustered by hospital. RESULTS: The response rate to our electronic survey was 77% (33 of 43 hospitals). The majority (85%) had an institutional bronchiolitis CPG in place. Hospitals with a CPG had universal agreement regarding recommendations against routine tests and treatments. The presence of a CPG was not associated with significant reductions in the use of tests and treatments (eg, complete blood count, chest radiography, bronchodilator use, steroid and antibiotic use). A longer interval duration since CPG implementation and presence of an easily accessible online CPG document were associated with significant reductions in the performance of complete blood count and chest radiography and the use of corticosteroids. Other implementation factors demonstrated mixed results. CONCLUSION: Most children's hospitals have an institutional bronchiolitis CPG in place. The content of these CPGs is largely uniform in practice recommendations against tests and treatments. The presence of institutional CPGs did not significantly reduce the ordering of tests and treatments. Online accessibility of a written CPG and prolonged duration of implementation reduce tests and treatments.

Children's hospitals with shorter lengths of stay do not have higher readmission rates.

OBJECTIVE: To test the hypothesis that children's hospitals with shorter length of stay (LOS) for hospitalized patients have higher all-cause readmission rates. STUDY DESIGN: Longitudinal, retrospective cohort study of the Pediatric Health Information System of 183616 admissions within 43 US children's hospitals for appendectomy, asthma, gastroenteritis, and seizure between July 2009 and June 2011. Admissions were stratified by medical complexity, based on whether patients had a complex chronic health condition, were neurologically impaired, or were assisted with medical technology. Outcome measures include LOS; all-cause readmission rates within 3, 7, 15, and 30 days; and the association between hospital-specific mean LOS and all-cause readmission rates as determined by linear regression. RESULTS: Mean LOS was <3 days for all patients across all conditions, except for appendectomy in complex patients (mean LOS 3.7 days, 95% CI 3.47-4.01). Condition-specific 3-, 7-, 15-, and 30-day all-cause readmission rates for noncomplex patients were all <5%. Condition-specific readmission rates for complex patients ranged from <1% at 3 days for seizures to 16% at 30 days for gastroenteritis. There was no linear association between hospital-specific, condition-specific mean LOS, stratified by medical complexity, and all-cause readmission rates at any time interval within 30 days (all P values ≥.10). CONCLUSION: In children's hospitals, LOS is short and readmission rates are low for asthma, appendectomy, gastroenteritis, and seizure admissions. In the conditions studied, there is no association between shorter hospital-specific LOS and higher readmission rates within the LOS observed.

Annual Variation in 30-Day Risk-Adjusted Readmission Rates in U.S. Children's Hospitals.

OBJECTIVE: Reducing pediatric readmissions has become a national priority; however, the use of readmission rates as a quality metric remains controversial. The goal of this study was to examine short-term stability and long-term changes in hospital readmission rates. METHODS: Data from the Pediatric Health Information System were used to compare annual 30-day risk-adjusted readmission rates (RARRs) in 47 US children's hospitals from 2016 to 2017 (short-term) and 2016 to 2019 (long-term). Pearson correlation coefficients and weighted Cohen's Kappa statistics were used to measure correlation and agreement across years for hospital-level RARRs and performance quartiles. RESULTS: Median (IQR) 30-day RARRs remained stable from 7.7% (7.0-8.3) in 2016 to 7.6% (7.0-8.1) in 2019. Individual hospital RARRs in 2016 were strongly correlated with the same hospital's 2017 rate (R2 = 0.89 [95% confidence interval (CI) 0.80-0.94]) and moderately correlated with those in 2019 (R2 = 0.49 [95%CI 0.23-0.68]). Short-term RARRs (2016 vs 2017) were more highly correlated for medical conditions than surgical conditions, but correlations between long-term medical and surgical RARRs (2016 vs 2019) were similar. Agreement between RARRs was higher when comparing short-term changes (0.73 [95%CI 0.59-0.86]) than long-term changes (0.45 [95%CI 0.27-0.63]). From 2016 to 2019, RARRs increased by ≥1% in 7 (15%) hospitals and decreased by ≥1% in 6 (13%) hospitals. Only 7 (15%) hospitals experienced reductions in RARRs over the short and long-term. CONCLUSIONS: Hospital-level performance on RARRs remained stable with high agreement over the short-term suggesting stability of readmission measures. There was little evidence of sustained improvement in hospital-level performance over multiple years.

Child Opportunity Index and Rehospitalization for Ambulatory Care Sensitive Conditions at US Children's Hospitals.

OBJECTIVE: Child Opportunity Index (COI) measures neighborhood contextual factors (education, health and environment, social and economic) that may influence child health. Such factors have been associated with hospitalizations for ambulatory care sensitive conditions (ACSC). Lower COI has been associated with higher health care utilization, yet association with rehospitalization(s) for ACSC remains unknown. Our objective is to determine the association between COI and ACSC rehospitalizations. METHODS: Multicenter retrospective cohort study of children ages 0 to 17 years with a hospital admission for ambulatory care sensitive conditions in 2017 or 2018. Exposure was COI. Outcome was rehospitalization within 1 year of index admission (analyzed as any or ≥2 rehospitalization) for ACSC. Logistic regression models adjusted for age, sex, severity, and complex and mental health conditions. RESULTS: The study included 184 478 children. Of hospitalizations, 28.3% were by children from very low COI and 16.5% were by children from very high COI neighborhoods. In risk-adjusted models, ACSC rehospitalization was higher for children from very low COI than very high COI neighborhoods; any rehospitalization occurred for 18.7% from very low COI and 13.5% from very high COI neighborhoods (adjusted odds ratio 1.14 [1.05-1.23]), whereas ≥2 rehospitalization occurred for 4.8% from very low COI and 3.2% from very high COI neighborhoods (odds ratio 1.51 [1.29-1.75]). CONCLUSIONS: Children from neighborhoods with low COI had higher rehospitalizations for ACSCs. Further research is needed to understand how hospital systems can address social determinants of health in the communities they serve to prevent rehospitalizations.

Follow-up After Pediatric Mental Health Emergency Visits.

OBJECTIVES: To examine how outpatient mental health (MH) follow-up after a pediatric MH emergency department (ED) discharge varies by patient characteristics and to evaluate the association between timely follow-up and return encounters. METHODS: We conducted a retrospective study of 28 551 children aged 6 to 17 years with MH ED discharges from January 2018 to June 2019, using the IBM Watson MarketScan Medicaid database. Odds of nonemergent outpatient follow-up, adjusted for sociodemographic and clinical characteristics, were estimated using logistic regression. Cox proportional hazard models were used to evaluate the association between timely follow-up and risk of return MH acute care encounters (ED visits and hospitalizations). RESULTS: Following MH ED discharge, 31.2% and 55.8% of children had an outpatient MH visit within 7 and 30 days, respectively. The return rate was 26.5% within 6 months. Compared with children with no past-year outpatient MH visits, those with ≥14 past-year MH visits had 9.53 odds of accessing follow-up care within 30 days (95% confidence interval [CI], 8.75-10.38). Timely follow-up within 30 days was associated with a 26% decreased risk of return within 5 days of the index ED discharge (hazard ratio, 0.74; 95% CI, 0.63-0.91), followed by an increased risk of return thereafter. CONCLUSIONS: Connection to outpatient care within 7 and 30 days of a MH ED discharge remains poor, and children without prior MH outpatient care are at highest risk for poor access to care. Interventions to link to outpatient MH care should prioritize follow-up within 5 days of an MH ED discharge.

Ambulatory follow-up among publicly insured children discharged from the emergency department.

BACKGROUND: While children discharged from the emergency department (ED) are frequently advised to follow up with ambulatory care providers, the extent to which this occurs is unknown. We sought to characterize the proportion of publicly insured children who have an ambulatory visit following ED discharge, identify factors associated with ambulatory follow-up, and evaluate the association of ambulatory follow-up with subsequent hospital-based health care utilization. METHODS: We performed a cross-sectional study of pediatric (<18 years) encounters during 2019 included in the IBM Watson Medicaid MarketScan claims database from seven U.S. states. Our primary outcome was an ambulatory follow-up visit within 7 days of ED discharge. Secondary outcomes were 7-day ED return visits and hospitalizations. Logistic regression and Cox proportional hazards were used for multivariable modeling. RESULTS: We included 1,408,406 index ED encounters (median age 5 years, IQR 2-10 years), for which a 7-day ambulatory visit occurred in 280,602 (19.9%). Conditions with the highest proportion of 7-day ambulatory follow-up included seizures (36.4%); allergic, immunologic, and rheumatologic diseases (24.6%); other gastrointestinal diseases (24.5%); and fever (24.1%). Ambulatory follow-up was associated with younger age, Hispanic ethnicity, weekend ED discharge, ambulatory encounters prior to the ED visit, and diagnostic testing performed during the ED encounter. Ambulatory follow-up was inversely associated with Black race and ambulatory care-sensitive or complex chronic conditions. In Cox models, ambulatory follow-up was associated with a higher hazard ratio (HR) of subsequent ED return (HR range 1.32-1.65) visit and hospitalization (HR range 3.10-4.03). CONCLUSIONS: One-fifth of children discharged from the ED have an ambulatory visit within 7 days, which varied by patient characteristics and diagnoses. Children with ambulatory follow-up have a greater subsequent health care utilization, including subsequent ED visit and/or hospitalization. These findings identify the need to further research the role and costs associated with routine post-ED visit follow-up.

Epidemiology and management of abdominal injuries in children.

BACKGROUND: Although more guideline-adherent care has been described in pediatric compared to adult trauma centers, we aimed to provide a more detailed characterization of management and resource utilization of children with intra-abdominal injury (IAI) within pediatric centers. Our primary objective was to describe the epidemiology, diagnostic evaluation, and management of children with IAI across U.S. children's hospitals. Our secondary objective was to describe the interhospital variation in surgical management of children with IAI. METHODS: We conducted a cross-sectional study of 33 hospitals in the Pediatric Health Information System. We included children aged <18 years evaluated in the emergency department from 2010 to 2019 with IAI, as defined by ICD coding, and who underwent an abdominal computed tomography (CT). Our primary outcome was abdominal surgery. We categorized IAI by organ system and described resource utilization data. We used generalized linear regression to calculate adjusted hospital-level proportions of abdominal surgery, with a random effect for hospital. RESULTS: We studied 9265 children with IAI. Median (IQR) age was 9.0 (6.0-13.0) years. Abdominal surgery was performed in 16% (n = 1479) of children, with the lowest proportion of abdominal surgery observed in children aged <5 years. Liver (38.6%) and spleen (32.1%) were the most common organs injured. A total of 3.1% of children with liver injuries and 2.8% with splenic injuries underwent abdominal surgery. Although there was variation in rates of surgery across hospitals (p < 0.001), only three of 33 hospitals had rates that were statistically different from the aggregate mean of 16%. CONCLUSIONS: Most children with IAI are managed nonoperatively, and most children's hospitals manage children with IAI similarly. These data can be used to inform future benchmarking efforts across hospitals to assess concordance with guidelines for the management of children with IAI.
