<p><strong>OBJECTIVE: </strong>To inform resource allocation toward a continuum of care for youth at risk of suicide, we examined unplanned 30-day readmissions after pediatric hospitalization for either suicide ideation (SI) or suicide attempt (SA).</p>
<p><strong>METHODS: </strong>We conducted a retrospective cohort study of a nationally representative sample of 133,516 hospitalizations for SI or SA among 6- to 17-year-olds to determine prevalence, risk factors, and characteristics of 30-day readmissions using the 2013 and 2014 Nationwide Readmissions Dataset (NRD). Risk factors for readmission were modeled using logistic regression.</p>
<p><strong>RESULTS: </strong>We identified 95,354 hospitalizations for SI and 38,162 hospitalizations for SA. Readmission rates within 30 days were 8.5% for SI and SA hospitalizations. Among 30-day readmissions, more than one-third (34.1%) occurred within 7 days. Among patients with any 30-day readmission, 11% had more than one readmission within 30 days. The strongest risk factors for readmission were SI or SA hospitalization in the 30 days preceding the index SI/SA hospitalization (adjusted odds ratio [AOR]: 3.14, 95% CI: 2.73-3.61) and hospitalization for other indications in the previous 30 days (AOR: 3.18, 95% CI: 2.67-3.78). Among readmissions, 94.5% were for a psychiatric condition and 63.4% had a diagnosis of SI or SA.</p>
<p><strong>CONCLUSIONS: </strong>Quality improvement interventions to reduce unplanned 30-day readmissions among children hospitalized for SI or SA should focus on children with a recent prior hospitalization and should be targeted to the first week following hospital discharge.</p>

<p><strong>OBJECTIVE: </strong>Mental health conditions (MHCs) are prevalent among hospitalized children and could influence the success of hospital discharge. We assessed the relationship between MHCs and 30-day readmissions.</p>
<p><strong>METHODS: </strong>This retrospective, cross-sectional study of the 2013 Nationwide Readmissions Database included 512,997 hospitalizations of patients ages 3 to 21 years for the 10 medical and 10 procedure conditions with the highest number of 30-day readmissions. MHCs were identified by using the International Classification of Diseases, 9th Revision-Clinical Modification codes. We derived logistic regression models to measure the associations between MHC and 30-day, all-cause, unplanned readmissions, adjusting for demographic, clinical, and hospital characteristics.</p>
<p><strong>RESULTS: </strong>An MHC was present in 17.5% of medical and 13.1% of procedure index hospitalizations. Readmission rates were 17.0% and 6.2% for medical and procedure hospitalizations, respectively. In the multivariable analysis, compared with hospitalizations with no MHC, hospitalizations with MHCs had higher odds of readmission for medical admissions (adjusted odds ratio [AOR], 1.23; 95% confidence interval [CI], 1.19-1.26] and procedure admissions (AOR, 1.24; 95% CI, 1.15-1.33). Three types of MHCs were associated with higher odds of readmission for both medical and procedure hospitalizations: depression (medical AOR, 1.57; 95% CI, 1.49-1.66; procedure AOR, 1.39; 95% CI, 1.17-1.65), substance abuse (medical AOR, 1.24; 95% CI, 1.18-1.30; procedure AOR, 1.26; 95% CI, 1.11-1.43), and multiple MHCs (medical AOR, 1.43; 95% CI, 1.37-1.50; procedure AOR, 1.26; 95% CI, 1.11-1.44).</p>
<p><strong>CONCLUSIONS: </strong>MHCs are associated with a higher likelihood of hospital readmission in children admitted for medical conditions and procedures. Understanding the influence of MHCs on readmissions could guide strategic planning to reduce unplanned readmissions for children with cooccurring physical and mental health conditions.</p>
<p><strong>OBJECTIVES: </strong>Suicide ideation (SI) and suicide attempts (SAs) have been reported as increasing among US children over the last decade. We examined trends in emergency and inpatient encounters for SI and SA at US children's hospitals from 2008 to 2015.</p>
<p><strong>METHODS: </strong>We used retrospective analysis of administrative billing data from the Pediatric Health Information System database.</p>
<p><strong>RESULTS: </strong>There were 115 856 SI and SA encounters during the study period. Annual percentage of all visits for SI and SA almost doubled, increasing from 0.66% in 2008 to 1.82% in 2015 (average annual increase 0.16 percentage points [95% confidence intervals (CIs) 0.15 to 0.17]). Significant increases were noted in all age groups but were higher in adolescents 15 to 17 years old (average annual increase 0.27 percentage points [95% CI 0.23 to 0.30]) and adolescents 12 to 14 years old (average annual increase 0.25 percentage points [95% CI 0.21 to 0.27]). Increases were noted in girls (average annual increase 0.14 percentage points [95% CI 0.13 to 0.15]) and boys (average annual increase 0.10 percentage points [95% CI 0.09 to 0.11]), but were higher for girls. Seasonal variation was also observed, with the lowest percentage of cases occurring during the summer and the highest during spring and fall.</p>
<p><strong>CONCLUSIONS: </strong>Encounters for SI and SA at US children's hospitals increased steadily from 2008 to 2015 and accounted for an increasing percentage of all hospital encounters. Increases were noted across all age groups, with consistent seasonal patterns that persisted over the study period. The growing impact of pediatric mental health disorders has important implications for children's hospitals and health care delivery systems.</p>
<p><strong>OBJECTIVES: </strong>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.</p>
<p><strong>STUDY DESIGN: </strong>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.</p>
<p><strong>RESULTS: </strong>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%.</p>
<p><strong>CONCLUSIONS: </strong>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.</p>
<p><strong>BACKGROUND AND OBJECTIVE: </strong>Like their adult counterparts, pediatric hospitals are increasingly at risk for financial penalties based on readmissions. Limited information is available on how the composition of a hospital's patient population affects performance on this metric and hence affects reimbursement for hospitals providing pediatric care. We sought to determine whether applying different readmission metrics differentially affects hospital performance based on the characteristics of patients a hospital serves.</p>
<p><strong>METHODS: </strong>We performed a cross-sectional analysis of 64 children's hospitals from the Children's Hospital Association Case Mix Comparative Database 2012 and 2013. We calculated 30-day observed-to-expected readmission ratios by using both all-cause (AC) and Potentially Preventable Readmissions (PPR) metrics. We examined the association between observed-to-expected rates and hospital characteristics by using multivariable linear regression.</p>
<p><strong>RESULTS: </strong>We examined a total of 1 416 716 hospitalizations. The mean AC 30-day readmission rate was 11.3% (range 4.3%-19.6%); the mean PPR rate was 4.9% (range 2.9%-6.9%). The average 30-day AC observed-to-expected ratio was 0.96 (range 0.63-1.23), compared with 0.95 (range 0.65-1.23) for PPR; 59% of hospitals performed better than expected on both measures. Hospitals with higher volumes, lower percentages of infants, and higher percentage of patients with low income performed worse than expected on PPR.</p>
<p><strong>CONCLUSIONS: </strong>High-volume hospitals, those that serve fewer infants, and those with a high percentage of patients from low-income neighborhoods have higher than expected PPR rates and are at higher risk of reimbursement penalties.</p>
<p><strong>BACKGROUND AND OBJECTIVES: </strong>Pneumonia is a leading cause of hospitalization and readmission in children. Understanding the patient characteristics associated with pneumonia readmissions is necessary to inform interventions to reduce avoidable hospitalizations and related costs. The objective of this study was to characterize readmission rates, and identify factors and costs associated with readmission among children previously hospitalized with pneumonia.</p>
<p><strong>METHODS: </strong>Retrospective cohort study of children hospitalized with pneumonia at the 43 hospitals included in the Pediatric Health Information System between January 1, 2008, and December 31, 2011. The primary outcome was all-cause readmission within 30 days after hospital discharge, and the secondary outcome was pneumonia-specific readmission. We used multivariable regression models to identify patient and hospital characteristics and costs associated with readmission.</p>
<p><strong>RESULTS: </strong>A total of 82 566 children were hospitalized with pneumonia (median age, 3 years; interquartile range 1-7). Thirty-day all-cause and pneumonia-specific readmission rates were 7.7% and 3.1%, respectively. Readmission rates were higher among children <1 year of age, as well as in patients with previous hospitalizations, longer index hospitalizations, and complicated pneumonia. Children with chronic medical conditions were more likely to experience all-cause (odds ratio 3.0; 95% confidence interval 2.8-3.2) and pneumonia-specific readmission (odds ratio 1.8; 95% confidence interval 1.7-2.0) compared with children without chronic medical conditions. The median cost of a readmission ($11 344) was higher than that of an index admission ($4495; P = .01). Readmissions occurred in 8% of pneumonia hospitalizations but accounted for 16.3% of total costs for all pneumonia hospitalizations.</p>
<p><strong>CONCLUSIONS: </strong>Readmissions are common after hospitalization for pneumonia, especially among young children and those with chronic medical conditions, and are associated with substantial costs.</p>
<p><strong>OBJECTIVE: </strong>To test the hypothesis that children's hospitals with shorter length of stay (LOS) for hospitalized patients have higher all-cause readmission rates.</p>
<p><strong>STUDY DESIGN: </strong>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.</p>
<p><strong>RESULTS: </strong>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).</p>
<p><strong>CONCLUSION: </strong>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.</p>
<p><strong>OBJECTIVE: </strong>To assess readmission rates identified by 3M-Potentially Preventable Readmissions software (3M-PPRs) in a national cohort of children's hospitals.</p>
<p><strong>STUDY DESIGN: </strong>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.</p>
<p><strong>RESULTS: </strong>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).</p>
<p><strong>CONCLUSIONS: </strong>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.</p>
