<p><strong>OBJECTIVE: </strong>Overuse of diagnostic tests is of particular concern for pediatric academic medical centers. Our objective was to measure variation in testing based on proportion of hospitalization during the day versus night and the association between attending in-house coverage on the teaching service and test utilization for hospitalized pediatric patients.</p>

<p><strong>METHODS: </strong>Electronic health record data from 11,567 hospitalizations to a large, Northeastern, academic pediatric hospital were collected between January 2007 and December 2010. The patient-level dataset included orders for laboratory and imaging tests, information about who placed the order, and the timing of the order. Using a cross-sectional effect modification analysis, we estimated the difference in test utilization attributable to attending in-house coverage.</p>

<p><strong>RESULTS: </strong>We found that admission to the teaching service was independently associated with higher utilization of laboratory and imaging tests. However, the number of orders was 0.76 lower (95% confidence interval:-1.31 to -0.21, P = .006) per 10% increase in the proportion in the share of the hospitalization that occurred during daytime hours on the teaching services, which is attributable to direct attending supervision.</p>

<p><strong>CONCLUSIONS: </strong>Direct attending care of hospitalized pediatric patients at night was associated with slightly lower diagnostic test utilization.</p>

<p><strong>BACKGROUND AND OBJECTIVES: </strong>Length of stay (LOS) is a common benchmarking measure for hospital resource use and quality. Observation status (OBS) is considered an outpatient service despite the use of the same facilities as inpatient status (IP) in most children's hospitals, and LOS calculations often exclude OBS stays. Variability in the use of OBS by hospitals may significantly impact calculated LOS. We sought to determine the impact of including OBS in calculating LOS across children's hospitals.</p>

<p><strong>METHODS: </strong>Retrospective cohort study of hospitalized children (age &lt;19 years) in 2017 from the Pediatric Health Information System (Children's Hospital Association, Lenexa, KS). Normal newborns, transfers, deaths, and hospitals not reporting LOS in hours were excluded. Risk-adjusted geometric mean length of stay (RA-LOS) for IP-only and IP plus OBS was calculated and each hospital was ranked by quintile.</p>

<p><strong>RESULTS: </strong>In 2017, 45 hospitals and 625 032 hospitalizations met inclusion criteria (IP = 410 731 [65.7%], OBS = 214 301 [34.3%]). Across hospitals, OBS represented 0.0% to 60.3% of total discharges. The RA-LOS (SD) in hours for IP and IP plus OBS was 75.2 (2.6) and 54.3 (2.7), respectively ( &lt; .001). For hospitals reporting OBS, the addition of OBS to IP RA-LOS calculations resulted in a decrease in RA-LOS compared with IP encounters alone. Three-fourths of hospitals changed ≥1 quintile in LOS ranking with the inclusion of OBS.</p>

<p><strong>CONCLUSIONS: </strong>Children's hospitals exhibit significant variability in the assignment of OBS to hospitalized patients and inclusion of OBS significantly impacts RA-LOS calculations. Careful consideration should be given to the inclusion of OBS when determining RA-LOS for benchmarking, quality and resource use measurements.</p>

<p><strong>BACKGROUND: </strong>Improvement initiatives promote safe and efficient care for hospitalized children. However, these may be associated with limited cost savings. In this article, we sought to understand the potential financial benefit yielded by improvement initiatives by describing the inpatient allocation of costs for common pediatric diagnoses.</p>

<p><strong>METHODS: </strong>This study is a retrospective cross-sectional analysis of pediatric patients aged 0 to 21 years from 48 children's hospitals included in the Pediatric Health Information System database from January 1, 2017, to December 31, 2017. We included hospitalizations for 8 common inpatient pediatric diagnoses (seizure, bronchiolitis, asthma, pneumonia, acute gastroenteritis, upper respiratory tract infection, other gastrointestinal diagnoses, and skin and soft tissue infection) and categorized the distribution of hospitalization costs (room, clinical, laboratory, imaging, pharmacy, supplies, and other). We summarized our findings with mean percentages and percent of total costs and used mixed-effects models to account for disease severity and to describe hospital-level variation.</p>

<p><strong>RESULTS: </strong>For 195 436 hospitalizations, room costs accounted for 52.5% to 70.3% of total hospitalization costs. We observed wide hospital-level variation in nonroom costs for the same diagnoses (25%-81% for seizure, 12%-51% for bronchiolitis, 19%-63% for asthma, 19%-62% for pneumonia, 21%-78% for acute gastroenteritis, 21%-63% for upper respiratory tract infection, 28%-69% for other gastrointestinal diagnoses, and 21%-71% for skin and soft tissue infection). However, to achieve a cost reduction equal to 10% of room costs, large, often unattainable reductions (&gt;100%) in nonroom cost categories are needed.</p>

<p><strong>CONCLUSIONS: </strong>Inconsistencies in nonroom costs for similar diagnoses suggest hospital-level treatment variation and improvement opportunities. However, individual improvement initiatives may not result in significant cost savings without specifically addressing room costs.</p>

<p>Low-value health care is pervasive in the United States, and clinicians need to be trained to be stewards of health care resources. Despite a mandate by the Accreditation Council for Graduate Medical Education to educate trainee physicians on cost awareness, only 10% of pediatric residency programs have a high-value care (HVC) curriculum. To meet this need, we set out to develop and evaluate the impact of High-Value Pediatrics, an open-access HVC curriculum. High-Value Pediatrics is a 3-part curriculum that includes 4 standardized didactics, monthly interactive morning reports, and an embedded HVC improvement project. Curriculum evaluation through an anonymous, voluntary survey revealed an improvement in the self-reported knowledge of health care costs, charges, reimbursement, and value ( &lt; .05). Qualitative results revealed self-reported behavior changes, and HVC improvement projects resulted in higher-value patient care. The implementation of High-Value Pediatrics is feasible and reveals improved knowledge and attitudes about HVC. HVC improvement projects augmented curricular knowledge gains and revealed behavior changes. It is imperative that formal high-value education be taught to every pediatric trainee to lead the culture change that is necessary to turn the tide against low-value health care. In addition, simultaneous work on faculty education and attention to the hidden curriculum of low-value care is needed for sustained and long-term improvements.</p>

<p><strong>Objectives: </strong>Develop and test a new metric to assess meaningful variability in inpatient flow.</p>

<p><strong>Methods: </strong>Using the pediatric administrative dataset, Pediatric Health Information System, that quantifies the length of stay (LOS) in hours, all inpatient and observation encounters with 21 common diagnoses were included from the calendar year 2013 in 38 pediatric hospitals. Two mutually exclusive composite groups based on diagnosis and presence or absence of an ICU hospitalization termed Acute Care Composite (ACC) and ICU Composite (ICUC), respectively, were created. These composites consisted of an observed-to-expected (O/E) LOS as well as an excess LOS percentage (ie, the percent of day beyond expected). Seven-day all-cause risk-adjusted rehospitalizations was used as a balancing measure. The combination of the ACC, the ICUC, and the rehospitalization measures forms this new metric.</p>

<p><strong>Results: </strong>The diagnosis groups in the ACC and the ICUC included 113,768 and 38,400 hospitalizations, respectively. The ACC had a median O/E LOS of 1.0, a median excess LOS percentage of 23.9% and a rehospitalization rate of 1.7%. The ICUC had a median O/E LOS of 1.1, a median excess LOS percentage of 32.3%, and rehospitalization rate of 4.9%. There was no relationship of O/E LOS and rehospitalization for either ACC or ICUC.</p>

<p><strong>Conclusions: </strong>This metric shows variation among hospitals and could allow a pediatric hospital to assess the performance of inpatient flow.</p>

<p><strong>BACKGROUND: </strong>Little is known about repeat testing for patients admitted to children's hospitals from the emergency department (ED).</p>

<p><strong>OBJECTIVE: </strong>The objective of this study was to describe the trend of repeat laboratory testing from a children's hospital ED.</p>

<p><strong>METHODS: </strong>Laboratory studies were analyzed for July 2002 to June 2010 for complete blood counts (CBCs; 7 years), basic metabolic panels (BMPs; 2.5 years), and coagulation studies (7 years) ordered and reordered in the ED within 8 hours for patients admitted to the hospital. Results for tests were generated and classified into high, low, and normal based on reference ranges. To reflect actual practice, we expanded the normal range from 95% of lower bound to 105% of upper bound.</p>

<p><strong>RESULTS: </strong>A total of 37,035 CBCs, 11,414 BMPs, and 3903 coagulation studies were ordered. Proportions of these tests repeated were 0.9%, 1.9%, and 1.9%, respectively. Mean time to repeat was 2 hours. For CBCs, 25% of repeats were for a missing component; 35% were for low platelet counts. Sixty-eight percent of initial BMPs were repeated for high potassium. Half of coagulation studies were repeated for high prothrombin time; 36% were repeated for a missing component. On repeat, 75% of BMPs with high potassium levels and 65% of CBCs with low platelet count returned normal values, but 16% of coagulation studies repeated for high prothrombin time returned normal values.</p>

<p><strong>CONCLUSIONS: </strong>Repeat ED laboratory testing occurs infrequently at a children's hospital, and a large proportion of repeats is attributed to missing results. When repeated, abnormal results on initial studies are often returned as normal.</p>

<p>Insurers are increasingly adopting narrow network strategies. Little is known about how these strategies may affect children's access to needed specialty care. We examined the percentage of pediatric specialty hospitalizations that would be beyond existing Medicare Advantage network adequacy distance requirements for adult hospital care and, as a secondary analysis, a pediatric adaptation of the Medicare Advantage requirements. We examined 748,920 hospitalizations at eighty-one children's hospitals that submitted data for the period October 2014-September 2015. Nearly half of specialty hospitalizations were outside the Medicare Advantage distance requirements. Under the pediatric adaptation, there was great variability among the hospitals, with the percent of hospitalizations beyond the distance requirements ranging from less than 1&nbsp;percent to 35&nbsp;percent. Instead of, or in addition to, time and distance standards, policy makers may need to consider more nuanced network definitions, including functional capabilities of the pediatric care network or clear exception policies for essential specialty care services.</p>

<p><strong>BACKGROUND: </strong>Significant disparities exist between patients of different races and with different family incomes; less is understood regarding community-level factors on outcomes.</p>

<p><strong>METHODS: </strong>In this study, we used linked data from the Pediatric Health Information System database and the US Census Bureau to examine associations between median annual household income by zip code and mortality, length of stay, inpatient standardized costs, and costs per day, over and above the effects of race and payer, first for children undergoing cardiac surgery (2005-2015) and then for all pediatric discharges (2012-2015). Median community-level income was examined as continuous and categorical (by quartile) predictors. Hierarchical logistic and censored linear regression models were constructed. To these models, patient and surgical characteristics, year, race, payer, state, urban or rural designation, and center fixed effects were added.</p>

<p><strong>RESULTS: </strong>We identified 101 013 cardiac surgical (and 857 833 total) hospitalizations from 46 institutions. Children from the lowest-income neighborhoods who were undergoing cardiac surgery had 1.18 times the odds of mortality (95% confidence interval [CI]: 1.03 to 1.35), 7% longer lengths of stay (CI: 1% to 14%), and 7% higher standardized costs (CI: 1% to 14%) than children from the highest-income neighborhoods. Results for all children were similar, both with and without any major chronic conditions. The effects of neighborhood were only partially explained by differences in race, payer, or the centers at which patients received care. There were no differences in costs per day.</p>

<p><strong>CONCLUSIONS: </strong>Children from lower-income neighborhoods are at increased risk of mortality and use more resource intensive care than children from higher-income communities, even after accounting for disparities between races, payers, and centers.</p>

<p><strong>OBJECTIVE: </strong>(1) To evaluate regional variation in costs of care for 3 inpatient pediatric conditions, (2) assess potential drivers of variation, and (3) estimate cost savings from reducing variation.</p>

<p><strong>DESIGN/SETTING: </strong>Retrospective cohort study of hospitalizations for asthma, diabetic ketoacidosis (DKA), and acute gastroenteritis (AGE) at 46 children</p>

<p><strong>MEASUREMENTS:</strong> Variation in trimmed standardized costs were assessed within and across regions. Linear mixed effects models were adjusted for patient- and encounter-level variables to assess drivers of variation.</p>

<p><strong>RESULTS:</strong> After adjusting for patient-level factors, variation remained. Using census division clusters, mean trimmed and adjusted total standardized costs were 120% higher for asthma ($1920 vs $4227), 46% higher for DKA ($7429 vs $10,881), and 150% higher for AGE ($3316 vs $8292) in the highest-cost compared with the lowest-cost region. Comparing hospitals in the same region, standardized costs were significantly different (P &lt; 0.001) for each condition in each region. Drivers of variation were encounter-level variables including length of stay and intensive care unit utilization. For this cohort, annual savings from reducing variation would equal $69.1 million at the interregional level and $25.2 million at the intraregional level.</p>

<p><strong>CONCLUSIONS:</strong> Pediatric hospital costs vary between and within regions. Future studies should examine how much of this variation is avoidable. To the extent that less spending does not compromise outcomes, care models may be adjusted to eliminate unwarranted variation and reduce costs.</p>
