Patterns of Electrolyte Testing at Children's Hospitals for Common Inpatient Diagnoses

Antibiotic route and outcomes for children hospitalized with pneumonia

BACKGROUND

Emerging evidence suggests that initial oral and intravenous (IV) antibiotics have similar efficacy in pediatric community-acquired pneumonia (CAP), but further data are needed.

OBJECTIVE

We determined the association between hospital-level initial oral antibiotic rates and outcomes in pediatric CAP.

DESIGNS, SETTINGS, AND PARTICIPANTS

This retrospective cohort study included children hospitalized with CAP at 43 hospitals in the Pediatric Health Information System (2016-2022). Hospitals were grouped by whether initial antibiotics were given orally in a high, moderate, or low proportion of patients.

MAIN OUTCOME AND MEASURES

Regression models examined associations between high versus low oral-utilizing hospitals and length of stay (LOS, primary outcome), intensive care unit (ICU) transfers, escalated respiratory care, complicated CAP, cost, readmissions, and emergency department (ED) revisits.

RESULTS

Initial oral antibiotics were used in 16% (interquartile range: 10%-20%) of 30,207 encounters, ranging from 1% to 68% across hospitals. Comparing high versus low oral-utilizing hospitals (oral rate: 32% [27%-47%] and 10% [9%-11%], respectively), there were no differences in LOS, intensive care unit, complicated CAP, cost, or ED revisits. Escalated respiratory care occurred in 1.3% and 0.5% of high and low oral-utilizing hospitals, respectively (relative ratio [RR]: 2.96 [1.12, 7.81]), and readmissions occurred in 1.5% and 0.8% (RR: 1.68 [1.31, 2.17]). Initial oral antibiotics varied across hospitals without a difference in LOS. While high oral-utilizing hospitals had higher escalated respiratory care and readmission rates, these were rare, the clinical significance of these small differences is uncertain, and there were no differences in other clinically relevant outcomes. This suggests some children may benefit from initial IV antibiotics, but most would probably do well with oral antibiotics.

Changing patterns of routine laboratory testing over time at children's hospitals

BACKGROUND

Research into low-value routine testing at children's hospitals has not consistently evaluated changing patterns of testing over time.

OBJECTIVES

To identify changes in routine laboratory testing rates at children's hospitals over ten years and the association with patient outcomes.

DESIGN, SETTINGS, AND PARTICIPANTS

We performed a multi-center, retrospective cohort study of children aged 0-18 hospitalized with common, lower-severity diagnoses at 28 children's hospitals in the Pediatric Health Information Systems database.

MAIN OUTCOMES AND MEASURES

We calculated average annual testing rates for complete blood counts, electrolytes, and inflammatory markers between 2010 and 2019 for each hospital. A >2% average testing rate change per year was defined as clinically meaningful and used to separate hospitals into groups: increasing, decreasing, and unchanged testing rates. Groups were compared for differences in length of stay, cost, and 30-day readmission or ED revisit, adjusted for demographics and case mix index.

RESULTS

Our study included 576,572 encounters for common, low-severity diagnoses. Individual hospital testing rates in each year of the study varied from 0.3 to 1.4 tests per patient day. The average yearly change in hospital-specific testing rates ranged from -6% to +7%. Four hospitals remained in the lowest quartile of testing and two in the highest quartile throughout all 10 years of the study. We grouped hospitals with increasing (8), decreasing (n = 5), and unchanged (n = 15) testing rates. No difference was found across subgroups in costs, length of stay, 30-day ED revisit, or readmission rates. Comparing resource utilization trends over time provides important insights into achievable rates of testing reduction.

Intravenous antibiotics for urinary tract infections in children with neurologic impairment

BACKGROUND

Children with high-intensity neurologic impairment (HINI) have an increased risk of urinary tract infection (UTI) and prolonged intravenous (IV) antibiotic exposure.

OBJECTIVE

To determine the association between short (≤3 days) and long (>3 days) IV antibiotic courses and UTI treatment failure in hospitalized children with HINI.

METHODS

We performed a retrospective cohort study examining UTI hospitalizations at 49 hospitals in the Pediatric Health Information System from 2016 to 2021 for children (1-18 years) with HINI. The primary outcome was UTI readmission within 30 days. Our secondary outcome was the association of hospital-level variation in short IV antibiotic course use with readmission. Readmission rates were compared between short and long courses using multivariable regression.

RESULTS

Of 5612 hospitalizations, 3840 (68.4%) had short IV antibiotic courses. In our adjusted model, children with short IV courses were less likely than with long courses to have a 30-day UTI readmission (4.0%, 95% CI [3.6%, 4.5%] vs. 6.3%, 95% CI [5.1%, 7.8%]). Despite marked hospital-level variation in short IV course use (50.0%-87.5% of hospitalizations), there was no correlation with readmissions.

CONCLUSIONS

Children with HINI hospitalized with UTI had low UTI readmission rates, but those who received long IV antibiotic courses were more likely to experience UTI readmission versus those receiving short courses. While residual confounding may influence our results, we did not find that short IV courses impacted readmission at the hospital level despite variation in use across institutions. Long IV antibiotic courses are associated with risks and may not confer benefit in this population.

A National Quality Improvement Collaborative to Improve Antibiotic Use in Pediatric Infections

BACKGROUND

Nearly 25% of antibiotics prescribed to children are inappropriate or unnecessary, subjecting patients to avoidable adverse medication effects and cost.

METHODS

We conducted a quality improvement initiative across 118 hospitals participating in the American Academy of Pediatrics Value in Inpatient Pediatrics Network 2020 to 2022. We aimed to increase the proportion of children receiving appropriate: (1) empirical, (2) definitive, and (3) duration of antibiotic therapy for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infections to ≥85% by Jan 1, 2022. Sites reviewed encounters of children >60 days old evaluated in the emergency department or hospital. Interventions included monthly audit with feedback, educational webinars, peer coaching, order sets, and a mobile app containing site-specific, antibiogram-based treatment recommendations. Sites submitted 18 months of baseline, 2-months washout, and 10 months intervention data. We performed interrupted time series (analyses for each measure.

RESULTS

Sites reviewed 43 916 encounters (30 799 preintervention, 13 117 post). Overall median [interquartile range] adherence to empirical, definitive, and duration of antibiotic therapy was 67% [65% to 70%]; 74% [72% to 75%] and 61% [58% to 65%], respectively at baseline and was 72% [71% to 72%]; 79% [79% to 80%] and 71% [69% to 73%], respectively, during the intervention period. Interrupted time series revealed a 13% (95% confidence interval: 1% to 26%) intercept change at intervention for empirical therapy and a 1.1% (95% confidence interval: 0.4% to 1.9%) monthly increase in adherence per month for antibiotic duration above baseline rates. Balancing measures of care escalation and revisit or readmission did not increase.

CONCLUSIONS

This multisite collaborative increased appropriate antibiotic use for community-acquired pneumonia, skin and soft tissue infections, and urinary tract infection among diverse hospitals.

Phlebotomy-free days in children hospitalized with common infections and their association with clinical outcomes

BACKGROUND

Phlebotomy for hospitalized children has consequences (e.g., pain, iatrogenic anemia), and unnecessary testing is a modifiable source of waste in healthcare. Days without blood draws or phlebotomy-free days (PFDs) has the potential to serve as a hospital quality measure.

OBJECTIVE

To describe: (1) the frequency of PFDs in children hospitalized with common infections and (2) the association of PFDs with clinical outcomes.

DESIGN, SETTINGS AND PARTICIPANTS

We performed a cross-sectional study of children hospitalized 2018-2019 with common infections at 38 hospitals using the Pediatric Health Information System database. We included infectious All Patients Refined Diagnosis Related Groups with a median length of stay (LOS) >2 days. We excluded patients with medical complexity, interhospital transfers, those receiving intensive care, and in-hospital mortality.

MAIN OUTCOME AND MEASURES

We defined PFDs as hospital days (midnight to midnight) without laboratory blood testing and measured the proportion of PFDs divided by total hospital LOS (PFD ratio) for each condition and hospital. Higher PFD ratios signify more days without phlebotomy. Hospitals were grouped into low, moderate, and high average PFD ratios. Adjusted outcomes (LOS, costs, and readmissions) were compared across groups.

RESULTS

We identified 126,135 encounters. Bronchiolitis (0.78) and pneumonia (0.54) had the highest PFD ratios (most PFDs), while osteoarticular infections (0.28) and gastroenteritis (0.30) had the lowest PFD ratios. There were no differences in adjusted clinical outcomes across PFD ratio groups. Among children hospitalized with common infections, PFD ratios varied across conditions and hospitals, with no association with outcomes. Our data suggest overuse of phlebotomy and opportunities to improve the care of hospitalized children.

Disparities in Management of Acute Gastroenteritis in Hospitalized Children

BACKGROUND AND OBJECTIVES

Acute gastroenteritis (AGE) is a common health care problem accounting for up to 200 000 pediatric hospitalizations annually. Previous studies show disparities in the management of children from different ethnic backgrounds presenting to the emergency department with AGE. Our aim was to evaluate whether differences in medical management also exist between Hispanic and non-Hispanic children hospitalized with AGE.

METHODS

We performed a single-center retrospective study of children aged 2 months to 12 years admitted to the pediatric hospital medicine service from January 2016 to December 2020 with a diagnosis of (1) acute gastroenteritis or (2) dehydration with feeding intolerance, vomiting, and/or diarrhea. Differences in clinical pathway use, diagnostic studies performed, and medical interventions ordered were compared between Hispanic and non-Hispanic patients.

RESULTS

Of 512 admissions, 54.9% were male, 51.6% were Hispanic, and 59.2% were on Medicaid. There was no difference between Hispanic and non-Hispanic patients in reported nausea or vomiting at admission, pathway use, or laboratory testing including stool studies. However, after adjusting for covariates, Hispanic patients had more ultrasound scans performed (odds ratio 1.65, 95% confidence interval 1.04-2.64) and fewer orders for antiemetics (odds ratio 0.53, 95% CI 0.29-0.95) than non-Hispanic patients.

CONCLUSIONS

Although there were no differences in many aspects of AGE management between Hispanic and non-Hispanic patients, there was still variability in ultrasound scans performed and antiemetics ordered, despite similarities in reported abdominal pain, nausea, and vomiting. Prospective and/or qualitative studies may be needed to clarify underlying reasons for these differences.

Factors Associated With Inpatient Subspecialty Consultation Patterns Among Pediatric Hospitalists

IMPORTANCE

Subspecialty consultation is a frequent, consequential practice in the pediatric inpatient setting. Little is known about factors affecting consultation practices.

OBJECTIVES

To identify patient, physician, admission, and systems characteristics that are independently associated with subspecialty consultation among pediatric hospitalists at the patient-day level and to describe variation in consultation utilization among pediatric hospitalist physicians.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study of hospitalized children used electronic health record data from October 1, 2015, through December 31, 2020, combined with a cross-sectional physician survey completed between March 3 and April 11, 2021. The study was conducted at a freestanding quaternary children's hospital. Physician survey participants were active pediatric hospitalists. The patient cohort included children hospitalized with 1 of 15 common conditions, excluding patients with complex chronic conditions, intensive care unit stay, or 30-day readmission for the same condition. Data were analyzed from June 2021 to January 2023.

EXPOSURES

Patient (sex, age, race and ethnicity), admission (condition, insurance, year), physician (experience, anxiety due to uncertainty, gender), and systems (hospitalization day, day of week, inpatient team, and prior consultation) characteristics.

MAIN OUTCOMES AND MEASURES

The primary outcome was receipt of inpatient consultation on each patient-day. Risk-adjusted consultation rates, expressed as number of patient-days consulting per 100, were compared between physicians.

RESULTS

We evaluated 15 922 patient-days attributed to 92 surveyed physicians (68 [74%] women; 74 [80%] with ≥3 years' attending experience) caring for 7283 unique patients (3955 [54%] male patients; 3450 [47%] non-Hispanic Black and 2174 [30%] non-Hispanic White patients; median [IQR] age, 2.5 ([0.9-6.5] years). Odds of consultation were higher among patients with private insurance compared with those with Medicaid (adjusted odds ratio [aOR], 1.19 [95% CI, 1.01-1.42]; P = .04) and physicians with 0 to 2 years of experience vs those with 3 to 10 years of experience (aOR, 1.42 [95% CI, 1.08-1.88]; P = .01). Hospitalist anxiety due to uncertainty was not associated with consultation. Among patient-days with at least 1 consultation, non-Hispanic White race and ethnicity was associated with higher odds of multiple consultations vs non-Hispanic Black race and ethnicity (aOR, 2.23 [95% CI, 1.20-4.13]; P = .01). Risk-adjusted physician consultation rates were 2.1 times higher in the top quartile of consultation use (mean [SD], 9.8 [2.0] patient-days consulting per 100) compared with the bottom quartile (mean [SD], 4.7 [0.8] patient-days consulting per 100; P < .001).

CONCLUSIONS AND RELEVANCE

In this cohort study, consultation use varied widely and was associated with patient, physician, and systems factors. These findings offer specific targets for improving value and equity in pediatric inpatient consultation.

Pharmacologic restraint use for children experiencing mental health crises in pediatric hospitals

BACKGROUND

Children in mental health crises are increasingly admitted to children's hospitals awaiting inpatient psychiatric placement. During hospitalization, patients may exhibit acute agitation prompting pharmacologic restraint use.

OBJECTIVE

To determine hospital-level incidence and variation of pharmacologic restraint use among children admitted for mental health conditions in children's hospitals.

DESIGN, SETTING, AND PARTICIPANTS

We examined data for children (5 to ≤18 years) admitted to children's hospitals with a primary mental health condition from 2018 to 2020 using the Pediatric Health Information System database. Hospital rates of parenteral pharmacologic restraint use per 1000 mental health bed days were determined and compared after adjusting for patient-level and demographic factors. Cluster analysis (k-means) was used to group hospitals based on overall restraint use (rate quartiles) and drug class. Hospital-level factors for pharmacologic restraint use were compared.

RESULTS

Of 29,834 included encounters, 3747 (12.6%) had pharmacologic restraint use. Adjusted hospital rates ranged from 35 to 389 pharmacologic restraint use days per 1000 mental health bed days with a mean of 175 (standard deviation: 72). Cluster analysis revealed three hospitals were high utilizers of all drug classes. No significant differences in pharmacologic restraint use were found in the hospital-level analysis.

CONCLUSIONS

Children's hospitals demonstrate wide variation in pharmacologic restraint rates for mental health hospitalizations, with a 10-fold difference in adjusted rates between highest and lowest utilizers, and high overall utilizers order medications across all drug classes.

Establishment of achievable benchmarks of care in the neurodiagnostic evaluation of simple febrile seizures

BACKGROUND

Current guidelines recommend against neurodiagnostic testing for the evaluation of simple febrile seizures.

OBJECTIVES

(1) Assess overall and institutional rates of neurodiagnostic testing and (2) establish achievable benchmarks of care (ABCs) for children evaluated for simple febrile seizures at children's hospitals.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional study of children 6 months to 5 years evaluated in the emergency department (ED) 2016-2019 with simple febrile seizures at 38 children's hospitals in Pediatric Health Information System database. We excluded children with epilepsy, complex febrile seizures, complex chronic conditions, and intensive care.

OUTCOME MEASURES

Proportions of children who received neuroimaging, electroencephalogram (EEG), or lumbar puncture (LP) and rates of hospitalization for study cohort and individual hospitals. Hospital-specific outcomes were adjusted for patient demographics and severity of illness. We utilized hospital-specific values for each measure to calculate ABCs.

RESULTS

We identified 51,015 encounters. Among the study cohort 821 (1.6%) children had neuroimaging, 554 (1.1%) EEG, 314 (0.6%) LP, and 2023 (4.0%) were hospitalized. Neurodiagnostic testing rates varied across hospitals: neuroimaging 0.4%-6.7%, EEG 0%-8.2%, LP 0%-12.7% in patients <1-year old and 0%-3.1% in patients ≥1 year. Hospitalization rate ranged from 0%-14.5%. Measured outcomes were higher among hospitalized versus ED-only patients: neuroimaging 15.3% versus 1.0%, EEG% 24.7 versus 0.1% (p < .001). Calculated ABCs were 0.6% for neuroimaging, 0.1% EEG, 0% LP, and 1.0% hospitalization.

CONCLUSIONS

Rates of neurodiagnostic testing and hospitalization for simple febrile seizures were low but varied across hospitals. Calculated ABCs were 0%-1% for all measures, demonstrating that adherence to current guidelines is attainable.

Effect of a Quality Improvement Bundle to Standardize the Use of Intravenous Fluids for Hospitalized Pediatric Patients: A Stepped-Wedge, Cluster Randomized Clinical Trial

IMPORTANCE

Given that hypotonic maintenance intravenous fluids (IVF) may cause hospital-acquired harm, in November 2018, the American Academy of Pediatrics released a clinical practice guideline recommending the use of isotonic IVF for patients aged 28 days to 18 years without contraindications. No recommendations were made regarding laboratory monitoring; however, unnecessary laboratory tests may contribute to health care waste and harm patients.

OBJECTIVE

To examine the effect of a quality improvement intervention bundle on (1) increasing the mean proportion of hours per hospital day with exclusive isotonic IVF use to at least 80% and (2) decreasing the mean proportion of hospital days with laboratory tests obtained.

DESIGN, SETTING, AND PARTICIPANTS

This stepped-wedge, cluster randomized clinical trial (Standardization of Fluids in Inpatient Settings [SOFI]) was sponsored by a national quality improvement collaborative and was conducted across 106 US pediatric hospitals. The SOFI intervention period was from September 2019 to March 2020.

INTERVENTIONS

Hospital sites were exposed to educational materials, a clinical algorithm and order set for IVF use, electronic medical record interventions to reduce laboratory testing, and "harms of overtesting" cards.

MAIN OUTCOMES AND MEASURES

Primary outcomes were mean proportion of hours per hospital day receiving exclusive isotonic IVF and mean proportion of hospital days with laboratory test values obtained. Secondary measures included total IVF duration per hospital day, daily patient weight measurement while receiving IVF, serum sodium testing, and adverse events. Baseline data were collected for 2 months; intervention period data, 7 months. Outcomes were analyzed using linear mixed-effects regression models.

RESULTS

A total of 106 hospitals were randomly assigned to 1 of 3 intervention start dates (wedges), and 100 hospitals (94%) completed the study. In total, 5215 hospitalizations were reviewed before the intervention, and 6724 hospitalizations were reviewed after the intervention. Prior to interventions, the mean (SD) proportion of hours per day with exclusive isotonic IVF use was 88.5% (31.7%). Interventions led to an absolute increase of 5.4% (95% CI, 3.9%-6.9%) above baseline in exclusive isotonic IVF use but did not change the proportion of hospital days during which a laboratory test value was obtained (estimated difference, 0.1%; 95% CI, -1.5% to 1.7%; P = .90), IVF use duration (estimated difference, -1.2%; 95% CI, -2.9% to 0.4%), serum sodium testing, or adverse events. There was an absolute increase of 4.4% (95% CI, 2.6%-6.2%) in the mean proportion of hospital days with a patient weight measurement while receiving IVF.

CONCLUSIONS AND RELEVANCE

In this stepped-wedge, cluster randomized clinical trial, an intervention bundle significantly improved the use of isotonic maintenance IVF without a concomitant increase in adverse events or electrolyte testing. Further work is required to deimplement laboratory testing.

Trends and Variation in Length of Stay Among Hospitalized Febrile Infants ≤60 Days Old

OBJECTIVES

Researchers in recent studies suggest that hospitalized febrile infants aged ≤60 days may be safely discharged if bacterial cultures are negative after 24-36 hours of incubation. We aimed to describe trends and variation in length of stay (LOS) for hospitalized febrile infants across children's hospitals.

METHODS

We conducted a multicenter retrospective cohort study of febrile infants aged ≤60 days hospitalized from 2016 to 2019 at 39 hospitals in the Pediatric Health Information System database. We excluded infants with complex chronic conditions, bacterial infections, lower respiratory tract viral infections, and those who required ICU admission. The primary outcomes were trends in LOS overall and for individual hospitals, adjusted for patient demographics and clinical characteristics. We also evaluated the hospital-level association between LOS and 30-day readmissions.

RESULTS

We identified 11 868 eligible febrile infant encounters. The adjusted mean LOS for the study cohort decreased from 44.0 hours in 2016 to 41.9 hours in 2019 (P < .001). There was substantial variation in adjusted mean LOS across children's hospitals, range 33.5-77.9 hours in 2016 and 30.4-100.0 hours in 2019. The change from 2016 to 2019 in adjusted mean LOS across individual hospitals also varied widely (-23.9 to +26.7 hours; median change -1.8 hours, interquartile range: -5.4 to 0.3). There was no association between hospital-level LOS and readmission rates (P = .70).

CONCLUSIONS

The LOS for hospitalized febrile infants decreased marginally between 2016 and 2019, although overall LOS and change in LOS varied substantially across children's hospitals. Continued quality improvement efforts are needed to reduce LOS for hospitalized febrile infants.

Safety Events in Children's Hospitals During the COVID-19 Pandemic

BACKGROUND AND OBJECTIVES

The coronavirus disease 2019 (COVID-19) pandemic has impacted hospitals, potentially affecting quality and safety. Our objective was to compare pediatric hospitalization safety events during the pandemic versus previous years.

METHODS

In this retrospective cohort study of hospitalizations in the Pediatric Health Information System, we compared Pediatric Quality Indicator (PDI) rates from March 15 to May 31, 2017-2019 (pre-COVID-19), with those from March 15 to May 31, 2020 (during COVID-19). Generalized linear mixed-effects models with adjustment for patient characteristics (eg, diagnosis, clinical severity) were used.

RESULTS

There were 399 113 discharges pre-COVID-19 and 88 140 during COVID-19. Unadjusted PDI rates were higher during versus pre-COVID-19 for overall PDIs (6.39 vs 5.05; P < .001). In adjusted analyses, odds of postoperative sepsis were higher during COVID-19 versus pre-COVID-19 (adjusted odds ratio 1.28 [95% confidence interval 1.04-1.56]). The remainder of the PDIs did not have increased adjusted odds during compared with pre-COVID-19.

CONCLUSIONS

Postoperative sepsis rates increased among children hospitalized during COVID-19. Efforts are needed to improve safety of postoperative care for hospitalized children.

Outcomes Associated With High- Versus Low-Frequency Laboratory Testing Among Hospitalized Children

BACKGROUND AND OBJECTIVES

Previous pediatric studies have revealed substantial variation in laboratory testing for specific conditions, but clinical outcomes associated with high- versus low-frequency testing are unclear. We hypothesized that hospitals with high- versus low-testing frequency would have worse clinical outcomes.

METHODS

We conducted a multicenter retrospective cohort study of patients 0 to 18 years old with low-acuity hospitalizations in the years 2018-2019 for 1 of 10 common All Patient Refined Diagnosis Related Groups. We identified hospitals with high-, moderate-, and low-frequency testing for 3 common groups of laboratory tests: complete blood cell count, basic chemistry studies, and inflammatory markers. Outcomes included length of stay, 7- and 30-day emergency department revisit and readmission rates, and hospital costs, comparing hospitals with high- versus low-frequency testing.

RESULTS

We identified 132 391 study encounters across 44 hospitals. Laboratory testing frequency varied by hospital and condition. We identified hospitals with high- (13), moderate- (20), and low-frequency (11) laboratory testing. When we compared hospitals with high- versus low-frequency testing, there were no differences in adjusted hospital costs (rate ratio 0.89; 95% confidence interval 0.71-1.12), length of stay (rate ratio 0.98; 95% confidence interval 0.91-1.06), 7-day (odds ratio 0.99; 95% confidence interval 0.81-1.21) or 30-day (odds ratio 1.01; 95% confidence interval 0.82-1.25) emergency department revisit rates, or 7-day (odds ratio 0.84; 95% confidence interval 0.65-1.25) or 30-day (odds ratio 0.91; 95% confidence interval 0.76-1.09) readmission rates.

CONCLUSIONS

In a multicenter study of children hospitalized for common low-acuity conditions, laboratory testing frequency varied widely across hospitals, without substantial differences in outcomes. Our results suggest opportunities to reduce laboratory overuse across conditions and children's hospitals.

Opportunities for Stewardship in the Transition From Intravenous to Enteral Antibiotics in Hospitalized Pediatric Patients

BACKGROUND/OBJECTIVE

Pediatric patients hospitalized with bacterial infections often receive intravenous (IV) antibiotics. Early transition to enteral antibiotics can reduce hospital duration, cost, and complications. We aimed to identify opportunities to transition from IV to enteral antibiotics, describe variation of transition among hospitals, and evaluate feasibility of novel stewardship metrics.

METHODS

This multisite retrospective cohort study used the Pediatric Health Information System to identify pediatric patients hospitalized with pneumonia, neck infection, orbital infection, urinary tract infection (UTI), osteomyelitis, septic arthritis, or skin and soft tissue infection (SSTI) between 2017 and 2018. Opportunity days were defined as days on which patients received both IV antibiotics and enteral medications, suggesting enteral tolerance. Percent opportunity was defined as opportunity days divided by days on any antibiotics. Both outcomes excluded IV antibiotics that have no alternative oral formulation. We evaluated outcomes per infection and antibiotic and assessed across-hospital variation.

RESULTS

We identified 88,522 aggregate opportunity days in 100,103 hospitalizations. On 57% of the antibiotic days, there was an opportunity to switch patients to enteral therapy, with greatest opportunity days in SSTI, neck infection, and pneumonia encounters, and with clindamycin, ceftriaxone, and ampicillin-sulbactam. Percent opportunity varied by infection (73% in septic arthritis to 40% in pneumonia). There was significant across-hospital variation in percent opportunity for all infections.

CONCLUSION

This multicenter study demonstrated the potential opportunity to transition from IV to enteral therapy in over half of antibiotic days. Opportunity varied by infection, antibiotic, and hospital. Across-hospital variation demonstrated likely missed opportunities for earlier transition and the need to define optimal transition times. Stewardship efforts promoting earlier transition for highly bioavailable antibiotics could reduce healthcare utilization and promote high-value care. We identified feasible stewardship metrics.

Learning from Each Other: A Multisite Collaborative to Reduce Electrolyte Testing

Inpatient electrolyte testing rates vary significantly across pediatric hospitals. Despite evidence that unnecessary testing exists, providers still struggle with reducing electrolyte laboratory testing. We aimed to reduce serum electrolyte testing among pediatric inpatients by 20% across 5 sites within 6 months.

METHODS

A national quality improvement collaborative evaluated standardized interventions for reducing inpatient serum electrolyte testing at 5 large tertiary and quaternary children's hospitals. The outcome measure was the rate of electrolyte laboratory tests per 10 patient-days. The interventions were adapted from a previous single-site improvement project and included cost card reminders, automated laboratory plans via electronic medical record, structured rounds discussions, and continued education. The collaborative utilized weekly conference calls to discuss Plan, Do, Study, Act cycles, and barriers to implementation efforts.

RESULTS

The study included 17,149 patient-days across 5 hospitals. The baseline preintervention electrolyte laboratory testing rate mean was 4.82 laboratory tests per 10 patient-days. Postimplementation, special cause variation in testing rates shifted the mean to 4.19 laboratory tests per 10 patient-days, a 13% reduction. There was a wide variation in preintervention electrolyte testing rates and the effectiveness of interventions between the hospitals participating in the collaborative.

CONCLUSIONS

This multisite improvement collaborative was able to rapidly disseminate and implement value improvement interventions leading to a reduction in electrolyte testing; however, we did not meet our goal of 20% testing reduction across all sites. Quality improvement collaboratives must consider variation in context when adapting previously successful single-center interventions to a wide variety of sites.

Trends and Variation in Care and Outcomes for Children Hospitalized With Acute Gastroenteritis

OBJECTIVES

Assess trends in inpatient acute gastroenteritis (AGE) management across children's hospitals and identify elements of AGE management associated with resource use.

METHODS

We examined inpatient stays for children 6 months to 18 years hospitalized with AGE from 2009 to 2018 using the Pediatric Health Information System database. We characterized demographics, hospital-level resource use (ie, medications, laboratories, and imaging), and outcomes (ie, cost per case, 14-day revisit rates, and length of stay [LOS]). We compared demographic characteristics and resource use between 2009 to 2013 and 2014 to 2018 using χ2 and Wilcoxon rank-sum tests. We grouped hospitals on the basis of 2009 use of each resource and trended use over time using logistic regression. Annual change in mean cost and LOS were estimated by using models of log-transformed data.

RESULTS

Across 32 354 hospitalizations at 38 hospitals, there was a high use of electrolyte testing (85.4%) and intravenous fluids (84.1%) without substantial changes over time. There were significant reductions in the majority of laboratory, medication, and imaging resources across hospitals over the study period. The most notable reductions were for rotavirus and stool testing. Many hospitals saw a decrease in LOS, with only 3 noting an increased revisit rate. Reductions in cost per case over time were most associated with decreases in imaging, laboratory testing, and LOS.

CONCLUSIONS

Significant variation in resource use for children hospitalized with AGE coupled with high use of resources discouraged in AGE guidelines highlights potential opportunities to improve resource use that may be addressed in future AGE guidelines and quality improvement initiatives.

Differences in the Receipt of Low-Value Services Between Publicly and Privately Insured Children

BACKGROUND

Children frequently receive low-value services that do not improve health, but it is unknown whether the receipt of these services differs between publicly and privately insured children.

METHODS

We analyzed 2013-2014 Medicaid Analytic eXtract and IBM MarketScan Commercial Claims and Encounters databases. Using 20 measures of low-value care (6 diagnostic testing measures, 5 imaging measures, and 9 prescription drug measures), we compared the proportion of publicly and privately insured children in 12 states who received low-value services at least once or twice in 2014; the proportion of publicly and privately insured children who received low-value diagnostic tests, imaging tests, and prescription drugs at least once; and the proportion of publicly and privately insured children eligible for each measure who received the service at least once.

RESULTS

Among 6 951 556 publicly insured children and 1 647 946 privately insured children, respectively, 11.0% and 8.9% received low-value services at least once, 3.9% and 2.8% received low-value services at least twice, 3.2% and 3.8% received low-value diagnostic tests at least once, 0.4% and 0.4% received low-value imaging tests at least once, and 8.4% and 5.5% received low-value prescription drug services at least once. Differences in the proportion of eligible children receiving each service were typically small (median difference among 20 measures, public minus private: +0.3 percentage points).

CONCLUSIONS

In 2014, 1 in 9 publicly insured and 1 in 11 privately insured children received low-value services. Differences between populations were modest overall, suggesting that wasteful care is not highly associated with payer type. Efforts to reduce this care should target all populations regardless of payer mix.
