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.

Parental Childhood Adversity and Pediatric Emergency Department Utilization: A Pilot Study.

OBJECTIVES: Adverse childhood experiences (ACEs) including physical, emotional, or sexual abuse; neglect; and/or exposure to household instability have been associated with adult emergency department utilization, but the impact of parental ACEs on pediatric emergency department (PED) utilization has not been studied. The primary aim was to determine if parental ACEs impact resource utilization as measured by (1) frequency of PED utilization, (2) acuity of PED visits, and (3) 72-hour PED return rates. The secondary aim was to determine if resilience interacts with the impact of parental ACEs on PED utilization. METHODS: This study is a cross-sectional survey using previously validated measures of ACEs, resiliency, and social determinants of health screening. Surveys were administered from October 17, 2019, to November 27, 2019, via iPad by research assistants in our institution's PEDs. Survey responses were linked to data abstracted from the electronic health record. Descriptive statistics were used to characterize our study population. Pearson correlation was used to identify correlation between ACEs, social determinants of health, and PED utilization measures. RESULTS: A total of 251 parents had complete data. Parental ACEs were positively associated with frequency of PED visits (incidence rate ratio, 1.013). In addition, high levels of parental resilience attenuated the association between parental ACEs and the number of severe acuity visits and were associated with fewer 72-hour return visits (incidence rate ratio, 0.49). CONCLUSIONS: Parental ACEs appear to be positively associated with frequency of PED utilization and inversely associated with higher-acuity PED visits and parental resiliency.

Pediatric emergency departments' readiness for change toward improving suicide prevention: A mixed-methods study with US leaders.

Objective: To assess pediatric emergency departments' (PEDs) current suicide prevention practices and climate for change to improve suicide prevention for youth. Methods: We conducted an explanatory, sequential mixed-methods study. First, we deployed a national, cross-sectional survey of PED leaders identified through publicly available data in Fall 2020, and then we conducted follow-up interviews with those who expressed interest. The survey queried each PED's suicide prevention practices and measured readiness for change to improve suicide prevention practices using questions scored on a 5-point Likert scale. Interviews gathered further, in-depth descriptions of PEDs' practices and culture. Interviews were audio-recorded, transcribed verbatim, and analyzed using a rapid analysis approach. Results: Of 135 PED directors eligible to complete the survey, 64 responded (response rate 47%). A total of 64% of PEDs had a mental health specialist available 24 hours/day, 7 days/week; 80% reported practicing mental health disposition planning, and 41% reported practicing psychiatric medication management. Altogether 91% of directors agreed or strongly agreed that their PED had a positive culture and 92% agreed/strongly agreed that their PED was ready for change. However, 31% disagreed/strongly disagreed that their PED had tools for evaluation and quality measurement. Resources needed for change (including budget, staffing, training, and facilities) varied across institutions. Interviews with our convenience sample of 21 directors revealed varying suicide prevention practices and confirmed that standardization, evaluation, and quality improvement initiatives were needed at most institutions. Leaders reported a high interest in improving care. Conclusions: PED leaders reported high motivation to improve suicide prevention services for young people, and reported needing quality improvement infrastructure to monitor and guide improvement.

The impact of COVID-19 on disease epidemiology, family dynamics, and social justice in Minnesota: All that you cannot see.

Objective: The COVID-19 pandemic presented a challenge to established seed grant funding mechanisms aimed at fostering collaboration in child health research between investigators at the University of Minnesota (UMN) and Children's Hospitals and Clinics of Minnesota (Children's MN). We created a "rapid response," small grant program to catalyze collaborations in child health COVID-19 research. In this paper, we describe the projects funded by this mechanism and metrics of their success. Methods: Using seed funds from the UMN Clinical and Translational Science Institute, the UMN Medical School Department of Pediatrics, and the Children's Minnesota Research Institute, a rapid response request for applications (RFAs) was issued based on the stipulations that the proposal had to: 1) consist of a clear, synergistic partnership between co-PIs from the academic and community settings; and 2) that the proposal addressed an area of knowledge deficit relevant to child health engendered by the COVID-19 pandemic. Results: Grant applications submitted in response to this RFA segregated into three categories: family fragility and disruption exacerbated by COVID-19; knowledge gaps about COVID-19 disease in children; and optimizing pediatric care in the setting of COVID-19 pandemic restrictions. A series of virtual workshops presented research results to the pediatric community. Several manuscripts and extramural funding awards underscored the success of the program. Conclusions: A "rapid response" seed funding mechanism enabled nascent academic-community research partnerships during the COVID-19 pandemic. In the context of the rapidly evolving landscape of COVID-19, flexible seed grant programs can be useful in addressing unmet needs in pediatric health.

Emergency Department Health Care Utilization and Opioid Administration Among Pediatric Patients With Sickle Cell Vasoocclusive Pain Crisis and Coexisting Mental Health Illness.

OBJECTIVES: To determine whether patients with sickle cell disease (SCD) who present to the emergency department (ED) with vasoocclusive pain crises (VOC), and have coexisting mental health (MH) diagnoses, are more likely to have increased health care utilization and more frequent opioid administration compared with those without coexisting MH conditions. METHODS: This is a retrospective study of patients aged 5 to 18 years with SCD who presented to a tertiary care ED with a primary complaint of VOC between January 1, 2013, and December 31, 2017. We excluded patients with sickle cell trait and without a pain management plan in the electronic medical record. Outcomes included ED length of stay (LOS), admission rate, and opioid administration in the ED. Morphine equivalents were used to standardize opioid dosing. Mann-Whitney U and χ2 tests were used for univariate analysis. Multivariable logistic was performed for categorical and continuous outcomes, respectively, after adjusting for confounding factors. RESULTS: We identified 978 encounters. We excluded 196 without a pain management plan and one with inaccurate ED LOS, resulting in 781 encounters (148 patients) for analysis. Coexisting MH diagnoses were present in 75.0% of encounters, with anxiety (83.0%) and depressive disorders (55.9%) being most common. Compared with SCD patients without coexisting MH diagnoses, those with coexisting MH diagnoses had significantly longer ED LOS (252 ± 139 minutes vs 232 ± 145 minutes, P = 0.03), longer median hospital LOS (1.4 ± 3.2 days vs 0.3 ± 2.4 days, P < 0.001) in univariate analyses, but these differences were no longer significant in adjusted regression models. Patients with coexisting MH diagnoses had higher frequency of opioid administration in the ED (85.6% vs 71.4%, P < 0.0001) and higher odds of receiving opioids (adjusted odds ratio, 2.07; 95% confidence interval, 1.28-3.33). CONCLUSIONS: Patients with SCD and coexisting MH diagnoses presenting with VOC have greater odds of receiving opioids compared with patients with SCD without coexisting MH diagnoses. Our results indicate a need for more MH resources in this vulnerable population and may help guide future management strategies.

Emergency Department Visits for Pediatric Firearm Injuries by Trauma Center Type.

OBJECTIVES: This study aimed to characterize pediatric visits to emergency departments (EDs) for firearm injuries and examine differences by trauma center type. METHODS: Analyses included all patients younger than 19 years from the National Trauma Data Bank, years 2009 to 2014. Trauma centers were categorized as adult, mixed adult and pediatric, or pediatric based on certification level. Baseline characteristics were compared between subgroups using χ2 tests. Multivariable logistic regression was used to examine risk of death. RESULTS: Of 466,403 pediatric ED visits, 21,416 (4.6%) resulted from a firearm injury. Most firearm injuries were treated at an adult (64.9%) or mixed trauma center (29.1%) and involved patients that were male (87.1%), in the 15- to 18-year age group (83.2%), and black or African American (61.3%). Most visits were for injuries resulting from assault (78.1%), followed by unintentional (12.6%) and self-inflicted (4.7%) injuries, undetermined intent (3.7%), and legal intervention (0.8%). Patients visiting EDs for firearm injuries had more than 7 times the odds of dying compared with patients with other injuries (odds ratio, 7.30; 95% confidence interval, 6.82-7.72), and firearm injuries were responsible for more than a quarter (26.1%) of the total pediatric deaths in the National Trauma Data Bank (n = 2866). Assault-related injuries resulted in the most deaths (n = 2010; 70.1%), but the case fatality rate was highest for self-inflicted (n = 453; 44.6%). CONCLUSION: We identified more than 20,000 firearm-related ED visits by pediatric patients from 2009 to 2014, averaging nearly 10 visits per day. Findings from this study can inform strategic planning in hospitals focused on preventing firearm injuries in children and adolescents.

Organ Donation Authorization After Brain Death Among Patients Admitted to PICUs in the United States, 2009-2018.

OBJECTIVES: To identify trends in and factors associated with pediatric organ donation authorization after brain death. DESIGN: Retrospective cohort study of data from Virtual Pediatric Systems, LLC (Los Angeles, CA). SETTING: Data from 123 PICUs reporting to Virtual Pediatric Systems from 2009 to 2018. PATIENTS: Patients less than 19 years old eligible for organ donation after brain death. MEASUREMENTS AND MAIN RESULTS: Of 2,777 eligible patients, 1,935 (70%) were authorized for organ donation; the authorization rate remained unchanged over time (ptrend = 0.22). In a multivariable logistic regression model, hospitalizations lasting greater than 7 days had lower odds of authorization (adjusted odds ratio, 0.5; p < 0.001 vs ≤ 1 d) and White patients had higher odds than other race/ethnicity groups. Authorization was higher for trauma-related encounters (adjusted odds ratio, 1.5; p < 0.001) and when donation was discussed with an organ procurement organization coordinator (adjusted odds ratio, 1.7; p < 0.001). Of 123 hospitals, 35 (28%) met or exceeded a 75% organ donation authorization target threshold; these hospitals more often had an organ procurement organization coordinator discussing organ donation (85% vs 72% of encounters; p < 0.001), but no difference was observed by PICU bed size. CONCLUSIONS: Organ donation authorization after brain death among PICU patients was associated with length of stay, race/ethnicity, and trauma-related encounter, and authorization rates were higher when an organ procurement organization coordinator was involved in the donation discussion. This study identified factors that could inform initiatives to improve the authorization process and increase pediatric organ donation rates.

Longitudinal Trends in Costs for Hospitalizations at Children's Hospitals.

OBJECTIVES: Children's hospitals are increasingly focused on value-based improvement efforts to improve outcomes and lower costs. Such efforts are generally focused on improving outcomes in specific conditions. Examination of cost drivers across all admissions may facilitate strategic prioritization of efforts. METHODS: Pediatric Health Information System data set discharges from 2010 to 2017 were aggregated into services lines and billing categories. The mean annual growth per discharge as a percentage of 2010 total costs was calculated for aggregated medical and surgical service lines and 6 individual service lines with highest rates of growth. The mean annual growth per discharge for each billing category and changes in length of stay was further assessed. RESULTS: The mean annual growth in total costs was similar for aggregated medical (2.6%) and surgical (2.7%) service lines. Individual medical service lines with highest mean annual growth were oncology (3.5%), reproductive services (2.9%), and nonsurgical orthopedics (2.8%); surgical service lines with highest rate of growth were solid organ transplant (3.7%), ophthalmology (3.3%), and otolaryngology (2.9%). CONCLUSIONS: Room costs contributed most consistently to cost increases without concomitant increases in length of stay. Value-based health care initiatives must focus on room cost increases and their impacts on patient outcomes.

Care of Pediatric High-Cost Hospitalizations Across Hospital Types.

BACKGROUND: High-cost hospitalizations (HCHs) account for a substantial proportion of pediatric health care expenditures. We aimed to (1) describe the distribution of pediatric HCHs across hospital types caring for children and (2) compare characteristics of pediatric HCHs by hospital type. METHODS: Cross-sectional analysis of all pediatric hospitalizations in the 2012 Kids' Inpatient Database. HCHs were defined as costs >$40 000 (94th percentile). Hospitals were categorized as children's, small general, and large general. RESULTS: Approximately 166 000 HCHs were responsible for 50.8% of aggregate hospital costs ($18.1 of $35.7 billion) and were mostly at children's hospitals (65%). Children with an HCH were largely neonates (45%), had public insurance (50%), and had ≥1 chronic condition (74%). A total of 131 children's hospitals cared for a median of 559 HCHs per hospital (interquartile range [IQR]: 355-1153) compared to 76 HCHs per hospital (IQR: 32-151) at 397 large general hospitals and 5 HCHs per hospital (IQR: 2-22) at 3581 small general hospitals. The median annual aggregate cost for HCHs was $60 million (IQR: $36-$135) per children's hospital compared to $6.6 million (IQR: $2-$15) per large general hospital and $300 000 (IQR: $116 000-$1.5 million) per small general hospital. HCHs from children's hospitals encompassed nearly 5 times as many unique clinical conditions as large general hospitals and >30 times as many as small general hospitals. CONCLUSIONS: Children's hospitals cared for a disproportionate volume, cost, and diversity of HCHs compared to general hospitals. Future studies should characterize the factors driving cost, resources, and reimbursement practices for HCH to ensure the long-term financial viability of the pediatric health care system.

Risk Factors for Compartment Syndrome in Pediatric Trauma Patients.

OBJECTIVE: This study aimed to identify risk factors for compartment syndrome (CS) in pediatric trauma populations. METHODS: We included patients younger than 19 years treated at trauma centers contributing to the National Trauma Data Bank between 2009 and 2012. Multivariable logistic regression was used to examine the association between risk factors and the development of CS. The final model adjusted for age, sex, race, number of comorbidities, Glascow Coma Scale, Injury Severity Score, mechanism of injury, and fracture of the lower limb. RESULTS: A total of 341,238 patients were eligible for analysis, and 896 patients developed CS (0.3%). In adjusted regression models, older patients had significantly higher odds of CS compared with patients 1 years or younger (odds ratio [OR], 3.29 [95% confidence interval [CI], 1.29-8.37; 2-6 years]; OR, 7.55 [95% CI, 3.08-18.55 [7-12 years]; OR, 10.34 [95% CI, 4.26-25.09 [13-18 years]). Male patients had significantly increased odds of CS compared with female patients, as did patients with lower limb fractures compared with patients without lower limb fractures (OR, 1.93 [95% CI, 1.56-2.40]; OR, 7.61 [95% CI, 6.48-8.94]; respectively). Finally, patients with a firearm injury had higher odds of CS compared with other mechanisms of injury (OR, 3.51 [95% CI, 2.70-4.56]). CONCLUSIONS: Older pediatric trauma patients, male patients, and those with lower limb fractures and firearm injuries have increased odds of CS. Information on risk factors can be used to help identify patients most likely to develop CS, facilitating timely diagnosis and treatment.

Trends in Pediatric Emergency Department Visits for Mental Health Conditions and Disposition by Presence of a Psychiatric Unit.

OBJECTIVE: To examine trends in mental health (MH) visits to pediatric emergency departments (EDs) and identify whether ED disposition varies by presence of a hospital inpatient psychiatric unit (IPU). STUDY DESIGN: Cross-sectional study of 8,479,311 ED visits to 35 children's hospitals from 2012 to 2016 for patients aged 3 to 21 years with a primary MH or non-MH diagnosis. Multivariable generalized estimating equations and bivariate Rao-Scott chi-square tests were used to examine trends in ED visits and ED disposition by IPU status, adjusted for clustering by hospital. RESULTS: From 2012 to 2016, hospitals experienced a greater increase in ED visits with a primary MH versus non-MH diagnosis (50.7% vs 12.7% cumulative increase, P < .001). MH visits were associated with patients who were older, female, white non-Hispanic, and privately insured compared with patients of non-MH visits (all P < .001). Forty-four percent of MH visits in 2016 had a primary diagnosis of depressive disorders or suicide or self-injury, and the increase in visits was highest for these diagnosis groups (depression: 109.8%; suicide or self-injury: 110.2%). Among MH visits, presence of a hospital IPU was associated with increased hospitalizations (34.6% vs 22.5%, P < .001) and less transfers (9.2% vs 16.2%, P < .001). CONCLUSION: The increase in ED MH visits from 2012 to 2016 was 4 times greater than non-MH visits at US children's hospitals and was primarily driven by patients diagnosed with depressive disorders and suicide or self-injury. Our findings have implications for strategic planning in tertiary children's hospitals dealing with a rising demand for acute MH care.

Unintentional Injuries in Primary and Secondary Schools in the United States, 2001-2013.

BACKGROUND: Unintentional injuries are the leading cause of youth morbidity. However, limited nationally representative data are available to characterize the occurrence of unintentional injuries at US schools. Given this paucity, we characterized secular trends in unintentional injuries at schools that led to emergency department (ED) visits. METHODS: A retrospective analysis of the National Electronic Injury Surveillance System-All Injury Program from 2001 to 2013 compared injuries occurring at schools to injuries occurring elsewhere in youth ages 5-18 years. Incidence rates were calculated using weighted frequency estimates as numerators and US population estimates as denominators. RESULTS: School injuries accounted for 21% of unintentional injury-related ED visits, with an estimated annual incidence rate of 1385 injuries per 100,000 5- to 18-year-olds. Middle school-aged youth (10-13 years) had the highest annual incidence rate (1640 per 100,000 youth) compared with younger and older counterparts. School injuries were more likely to be due to sports/recreation than nonschool injuries (55% vs 41%, p < .0001). Importantly, no detectable change in incidence rates of school injuries between 2001 and 2013 was found (p = .11). CONCLUSIONS: Stagnant annual incidence rates of unintentional injuries at schools and large numbers of school-based injuries demonstrate that school-based injuries are a notable opportunity for future prevention efforts.

Parasagittal vertex clots on head CT in infants with subdural hemorrhage as a predictor for abusive head trauma.

BACKGROUND: Abusive head trauma (AHT) is the most common cause of subdural hemorrhage (SDH) in infants younger than 12 months old. Clot formation in the parasagittal vertex seen on imaging has been associated with SDH due to AHT. There have been very few studies regarding these findings; to our knowledge, no studies including controls have been performed. OBJECTIVE: To describe parasagittal vertex clots on head computed tomography (CT) in infants with SDH and AHT compared to patients with SDH and accidental trauma, and to evaluate for parasagittal vertex clots in the absence of SDH in the setting of known accidental head trauma. MATERIALS AND METHODS: All infants younger than 12 months old with SDH present on CT scan were retrospectively identified from 2004 to 2014. Blinded, independent review of all CT scans for clot formation at the parasagittal vertex was performed by a pediatric neuroradiologist. RESULTS: Ninety-nine patients were eligible for analysis. Mean age was 4 months. Fifty-seven (57.6%) were male. Fifty-five (55.6%) patients were identified as having AHT and 22 (22.2%) had accidental trauma. Forty-five (81.2%) patients with AHT had parasagittal vertex clots present on CT scan compared to 8 (36.4%) patients with accidental trauma. Compared to patients without parasagittal vertex clots, those with parasagittal vertex clots were more likely to have AHT (66.2% vs. 32.3%, P=0.001), no known mechanism of injury (69.1% vs. 32.3%, P=0.015), retinal hemorrhage (75% vs. 35.5%, P=0.002) and hypoxic-ischemic changes (25% vs. 0%, P=0.002). Patients with parasagittal vertex clots have eight times the odds of AHT compared to patients without parasagittal vertex clots. Age-matched control patients who underwent head CT scan due to a history of accidental head injury without SDH were identified (n=87); no patient in the control group had parasagittal vertex clots. CONCLUSION: The finding of parasagittal vertex clots on CT scans should raise suspicion for abuse and prompt further investigation, especially in the setting of no known, uncertain or inconsistent mechanism of injury.

ICD Social Codes: An Underutilized Resource for Tracking Social Needs.

BACKGROUND: Social determinants of health (SDH) data collected in health care settings could have important applications for clinical decision-making, population health strategies, and the design of performance-based incentives and penalties. One source for cataloging SDH data is the International Statistical Classification of Diseases and Related Health Problems (ICD). OBJECTIVE: To explore how SDH are captured with ICD Ninth revision SDH V codes in a national inpatient discharge database. MATERIALS AND METHODS: Data come from the 2013 Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample, a national stratified sample of discharges from 4363 hospitals from 44 US states. We estimate the rate of ICD-9 SDH V code utilization overall and by patient demographics and payer categories. We additionally estimate the rate of SDH V code utilization for: (a) the 5 most common reasons for hospitalization; and (b) the 5 conditions with the highest rates of SDH V code utilization. RESULTS: Fewer than 2% of overall discharges in the National Inpatient Sample were assigned an SDH V code. There were statistically significant differences in the rate of overall SDH V code utilization by age categories, race/ethnicity, sex, and payer (all P<0.001). Nevertheless, SDH V codes were assigned to <7% of discharges in any demographic or payer subgroup. SDH V code utilization was highest for major diagnostic categories related to mental health and alcohol/substance use-related discharges. CONCLUSIONS: SDH V codes are infrequently utilized in inpatient settings for discharges other than those related to mental health and alcohol/substance use. Utilization incentives will likely need to be developed to realize the potential benefits of cataloging SDH information.

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.

Injury Region and Risk of Hospital-Acquired Pneumonia Among Pediatric Trauma Patients.

OBJECTIVE: To describe the relationship between injury region and risk of hospital-acquired pneumonia (HAP) in pediatric trauma patients. METHODS: Analyses included patients <19 years of age from the National Trauma Data Bank, during 2009-2011. Multivariable logistic regression was used to examine the association between injury region and odds of developing HAP stratified by age group. RESULTS: A total of 71 377 patients were eligible for analysis, and 1818 patients developed pneumonia. In adjusted regression models both younger (11-15 years) and older (16-18 years) adolescents with multisite injuries including the head and neck had higher odds of developing HAP compared with adolescents with isolated head and neck injuries (odds ratio [OR] = 2.04, 95% confidence interval [CI] 1.34-3.10; OR = 1.47, 95% CI 1.14-1.89, respectively), and younger adolescents with multisite injuries not involving the head and neck also had higher odds of developing HAP (OR = 1.97, 95% CI 1.08-3.60). We found no significant association between injury region and risk of HAP in children <11 years of age. Younger and older adolescents with firearm (OR = 1.85, 95% CI 1.00-3.42; OR = 1.39, 95% CI 1.02-1.88, respectively) or pulmonary (OR = 3.78, 95% CI 1.26-11.3; OR = 2.56, 95% CI 1.01-6.51, respectively) injuries had higher odds of developing HAP compared with those with motor vehicle collision injuries. CONCLUSIONS: Adolescent trauma patients with multisite injuries including the head and neck have a higher risk of developing HAP compared with those with isolated head and neck injuries. We identified several risk factors that can be used to inform future research focused on identifying subgroups at high risk for the development of HAP.

Higher Diet Quality in Adolescence and Dietary Improvements Are Related to Less Weight Gain During the Transition From Adolescence to Adulthood.

OBJECTIVES: To examine the previously validated A Priori Diet Quality Score (APDQS), and weight change among adolescents transitioning into young adulthood. STUDY DESIGN: Young people were recruited in middle/high schools and followed for 10 years. Participants reported diet and weight in 1999 (mean age, 15 years), 2004 (20 years), and 2009 (25 years). The analytic sample (n = 2656) had dietary intake assessments in 1999 and at least one other assessment. The APDQS (without alcoholic items) was based on 13 beneficial food groups, 12 adverse food groups, and 9 neutral food groups to capture aspects of Mediterranean/prudent diets, focusing on foods that are varied, based on nutritionally rich plants, and less processed. RESULTS: From mean age 15 to 25 years, mean (SD) weight increased from 61.0 (14.7) kg to 76.1 (18.8) kg, and APDQS increased from 43.1 (11.1) points to 45.6 (10.7) points. Within-person tracking correlation of the APDQS was 0.35 at mean age 15-20 years, increasing to 0.49 at 20-25 years. Independent of lifestyle factors and energy intake, a 15-point (IQR) higher APDQS in 1999 was associated with 1.5 kg (95% CI, 0.7-2.3 kg) less weight gain over 10 years, The increase in APDQS over time was similarly associated with less concurrent weight gain. Findings were stronger for models of excess weight gain. CONCLUSION: Higher diet quality, based on an assessment of dietary patterns in and after adolescence, was associated with reduced weight gain during the next 10 years. Establishment of high-quality dietary patterns in adolescence may help mitigate excess weight gain by young adulthood.

Association of Social Determinants With Children's Hospitals' Preventable Readmissions Performance.

IMPORTANCE: Performance-measure risk adjustment is of great interest to hospital stakeholders who face substantial financial penalties from readmissions pay-for-performance (P4P) measures. Despite evidence of the association between social determinants of health (SDH) and individual patient readmission risk, the effect of risk adjusting for SDH on readmissions P4P penalties to hospitals is not well understood. OBJECTIVE: To determine whether risk adjustment for commonly available SDH measures affects the readmissions-based P4P penalty status of a national cohort of children's hospitals. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 43 free-standing children's hospitals within the Pediatric Health Information System database in the calendar year 2013. We evaluated hospital discharges from 2013 that met criteria for 3M Health Information Systems' potentially preventable readmissions measure for calendar year 2013. The analysis was conducted from July 2015 to August 2015. EXPOSURES: Two risk-adjustment models: a baseline model adjusted for severity of illness and an SDH-enhanced model that adjusted for severity of illness and the following 4 SDH variables: race, ethnicity, payer, and median household income for the patient's home zip code. MAIN OUTCOMES AND MEASURES: Change in a hospital's potentially preventable readmissions penalty status (ie, change in whether a hospital exceeded the penalty threshold) using an observed-to-expected potentially preventable readmissions ratio of 1.0 as a penalty threshold. RESULTS: For the 179,400 hospital discharges from the 43 hospitals meeting inclusion criteria, median (interquartile range [IQR]) hospital-level percentages for the SDH variables were 39.2% nonwhite (n = 71,300; IQR, 28.6%-54.6%), 17.9% Hispanic (n = 32,060; IQR, 6.7%-37.0%), and 58.7% publicly insured (n = 106,116; IQR, 50.4%-67.8%). The hospital median household income for the patient's home zip code was $ 40,674 (IQR, $ 35,912-$ 46,190). When compared with the baseline model, adjustment for SDH resulted in a change in penalty status for 3 hospitals within the 15-day window (2 were no longer above the penalty threshold and 1 was newly penalized) and 5 hospitals within the 30-day window (3 were no longer above the penalty threshold and 2 were newly penalized). CONCLUSIONS AND RELEVANCE: Risk adjustment for SDH changed hospitals' penalty status on a readmissions-based P4P measure. Without adjusting P4P measures for SDH, hospitals may receive penalties partially related to patient SDH factors beyond the quality of hospital care.
