Aspiration and Non-Aspiration Pneumonia in Hospitalized Children With Neurologic Impairment

Pediatric Patients With Acute Flaccid Myelitis: Long-term Respiratory and Neurologic Outcomes

BACKGROUND

Acute flaccid myelitis (AFM), an infection-mediated neurologic condition, may be accompanied by respiratory failure and subsequent variable recovery. This study assessed and provided prescriptive data on long-term respiratory and neurologic outcomes according to respiratory status at the time of presentation.

METHODS

This was a retrospective cohort study using a large, single-payer healthcare database to identify children 1-18 years old, diagnosed with AFM between January 1, 2011 and December 31, 2019. Descriptive statistics described the overall cohort and the cohort by respiratory failure status. Bivariate analyses evaluated incidence rate ratios of outcome data, comparing those with respiratory failure to those without.

RESULTS

A total of 37 patients met the study criteria for AFM; 28 were from a previously established cohort. Median follow-up time was 4.7 years [interquartile range (IQR): 2.39-6.06]. Overall incidence rate of AFM over the study period was 0.6 per 100,000 person-years. Eight patients (21.6%) had respiratory failure during the index hospitalization. Among children with respiratory failure, 6 patients (75%) required follow-up respiratory support. Those with respiratory failure had higher Modified Rankin Scores [mean difference 1.29, 95% confidence interval (CI): 0.34-2.23] and a higher rate of respiratory-related emergency and in-hospital visits (incidence rate ratios 1.94; 95% CI: 1.27-2.96) compared to those without respiratory failure.

CONCLUSIONS

Having respiratory failure at presentation was observed to have worse outcomes, including the need for long-term respiratory support, higher healthcare utilization, and prolonged neurologic deficits. This study contributes to the scant literature on pediatric patients with AFM.

Compliance with antibiotic therapy guidelines in french paediatric intensive care units: a multicentre observational study

BACKGROUND

Bacterial infections (BIs) are widespread in ICUs. The aims of this study were to assess compliance with antibiotic recommendations and factors associated with non-compliance.

METHODS

We conducted an observational study in eight French Paediatric and Neonatal ICUs with an antimicrobial stewardship programme (ASP) organised once a week for the most part. All children receiving antibiotics for a suspected or proven BI were evaluated. Newborns < 72 h old, neonates < 37 weeks, age ≥ 18 years and children under surgical antimicrobial prophylaxis were excluded.

RESULTS

139 suspected (or proven) BI episodes in 134 children were prospectively included during six separate time-periods over one year. The final diagnosis was 26.6% with no BI, 40.3% presumed (i.e., not documented) BI and 35.3% documented BI. Non-compliance with antibiotic recommendations occurred in 51.1%. The main reasons for non-compliance were inappropriate choice of antimicrobials (27.3%), duration of one or more antimicrobials (26.3%) and length of antibiotic therapy (18.0%). In multivariate analyses, the main independent risk factors for non-compliance were prescribing ≥ 2 antibiotics (OR 4.06, 95%CI 1.69-9.74, p = 0.0017), duration of broad-spectrum antibiotic therapy ≥ 4 days (OR 2.59, 95%CI 1.16-5.78, p = 0.0199), neurologic compromise at ICU admission (OR 3.41, 95%CI 1.04-11.20, p = 0.0431), suspected catheter-related bacteraemia (ORs 3.70 and 5.42, 95%CIs 1.32 to 15.07, p < 0.02), a BI site classified as "other" (ORs 3.29 and 15.88, 95%CIs 1.16 to 104.76, p < 0.03), sepsis with ≥ 2 organ dysfunctions (OR 4.21, 95%CI 1.42-12.55, p = 0.0098), late-onset ventilator-associated pneumonia (OR 6.30, 95%CI 1.15-34.44, p = 0.0338) and ≥ 1 risk factor for extended-spectrum β-lactamase-producing Enterobacteriaceae (OR 2.56, 95%CI 1.07-6.14, p = 0.0353). Main independent factors for compliance were using antibiotic therapy protocols (OR 0.42, 95%CI 0.19-0.92, p = 0.0313), respiratory failure at ICU admission (OR 0.36, 95%CI 0.14-0.90, p = 0.0281) and aspiration pneumonia (OR 0.37, 95%CI 0.14-0.99, p = 0.0486).

CONCLUSIONS

Half of antibiotic prescriptions remain non-compliant with guidelines. Intensivists should reassess on a day-to-day basis the benefit of using several antimicrobials or any broad-spectrum antibiotics and stop antibiotics that are no longer indicated. Developing consensus about treating specific illnesses and using department protocols seem necessary to reduce non-compliance. A daily ASP could also improve compliance in these situations.

Antibiotics for the treatment of lower respiratory tract infections in children with neurodisability: Systematic review

AIM

Determine the optimal antibiotic choice for lower respiratory tract infection (LRTI) in children with neurodisability.

METHODS

Embase, Ovid Emcare and MEDLINE were searched for studies from inception to January 2023. All studies, except case reports, focusing on the antibiotic treatment of LRTI in children, with neurodisabilities were included. Outcomes included length of stay, intensive care admission and mortality.

RESULTS

Nine studies met the inclusion criteria (5115 patients). All the studies were of low quality. The shortest length of stay was with anaerobic and gram-positive cover. Five studies used anaerobic, gram-positive and gram-negative cover (e.g., amoxicillin-clavulanic acid), which was frequently adequate. In one large study, it was better than gram-positive and gram-negative cover alone (e.g. ceftriaxone). Those unresponsive or more unwell at presentation improved faster on Pseudomonas aeruginosa cover (e.g., piperacillin-tazobactam).

CONCLUSION

In this context, anaerobic, gram-positive and gram-negative cover is just as effective as P. aeruginosa cover, supporting empiric treatment with amoxicillin-clavulanic acid. If there is a failure to improve, broadening to include P. aeruginosa could be considered. This is consistent with a consensus statement on the treatment of LRTI in children with neurodisability. An accepted definition for what constitutes LRTI in this cohort is required before designing prospective randomised trials.

A systematic review of the perspectives of botulinum toxin use on the quality of life of neurological patients with drooling

OBJECTIVE

To investigate the effectiveness of botulinum toxin in the salivary glands of patients with neurological impairment and drooling and its impact on the quality of life.

MATERIALS AND METHODS

This systematic review was registered with the International Prospective Register of Systematic Reviews (CRD 42,023,435,242) and conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses. An electronic search was performed in the PubMed/MEDLINE, Embase, Scopus, Cochrane Library, and clinical trial databases until August 2023, no language restriction. Cohort studies and randomized clinical trials of patients diagnosed with drooling and neurological impairment who used botulinum toxin on the salivary gland were included, which evaluated subjective quality of life parameters. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist and Risk of Bias 2 tools. The certainty of the evidence was analyzed using the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Eight studies involving 317 patients were included. All studies, through subjective parameters, suggested the effectiveness of botulinum toxin in reducing drooling, resulting in an improvement in the quality of life. Three studies demonstrated improvements in swallowing and four in cases of respiratory diseases. Two clinical trials had a high risk of bias, whereas one had low risk. The five cohort studies that were evaluated had a high risk of bias. The certainty of the evidence was considered low.

CONCLUSIONS

Based on the patient/caregivers' perception of improvement in drooling, dysphagia, and respiratory symptoms, it can be inferred that botulinum toxin application reduces subjective drooling in neurologically compromised patients. Its impact contributes to the general well-being and quality of life.

CLINICAL RELEVANCE

Injection of botulinum toxin into the salivary glands can be considered an alternative technique to surgical or medicinal approaches in reducing drooling. It is effective, less invasive and without significant side effects. It promotes a positive impact on the well-being and quality of life of neurological patients.

Clinical Feeding and Swallowing Evaluation for the School-Based Speech-Language Pathologist

PURPOSE

From preschool through high school, eating is part of the school day. Children with feeding and/or swallowing issues are now in our neighborhood schools, our responsibility in our care, and require adequate nutrition and hydration to participate in school and access the curriculum. The whole child is in school, including all of their medical, behavioral, social, and educational needs. This clinical focus article describes a holistic process of evaluating swallowing and feeding in the school setting for the school speech-language pathologist (SLP) leading the team supporting the child.

METHOD

This clinical focus article explores the evaluation process in the educational setting for the school SLP in identification of pediatric feeding disorders (PFDs), which can involve dysphagia. Detailed descriptions of the related U.S. educational law, PFD, assessment processes for the multiple systems relating to eating, and collaboration with an interdisciplinary team are highlighted. Using the four overlapping domains of PFD (medical, psychosocial, feeding skill-based systems and associated nutritional aspects), medical and background history gathering; integration with instrumental results; and the need to consider the complex interaction of developmental, physical, cognitive, social, behavioral, family, and cultural aspects in the evaluation are detailed.

CONCLUSIONS

School-age children require safe and adequate nutrition and hydration for learning and social participation. The SLP has a lead role in the school team in evaluating swallowing and feeding, and developing a plan for team implementation. A holistic school-based SLP clinical evaluation process is described.

Unplanned Readmissions in Children with Medical Complexity in Saudi Arabia: A Large Multicenter Study

Background

Children with medical complexity (CMC) account for a substantial proportion of healthcare spending, and one-third of their expenditures are due to readmissions. However, knowledge regarding the healthcare-resource utilization and characteristics of CMC in Saudi Arabia is limited.

Objectives

To describe hospitalization patterns and characteristics of Saudi CMC with an unplanned 30-day readmission.

Methodology

This retrospective study included Saudi CMC (aged 0-14 years) who had an unplanned 30-day readmission at six tertiary centers in Riyadh, Jeddah, Dammam, Alahsa, and Almadina between January 2016 and December 2020. Hospital-based inclusion criteria focused on CMC with multiple complex chronic conditions (CCCs) and technology assistance (TA) device use. CMC were compared across demographics, clinical characteristics, and hospital-resource utilization.

Results

A total of 9139 pediatric patients had unplanned 30-day readmission during the study period, of which 680 (7.4%) met the inclusion criteria. Genetic conditions were the most predominant primary pathology (66.3%), with one-third of cases (33.7%) involving the neuromuscular system. During the index admission, pneumonia was the most common diagnosis (33.1%). Approximately 35.1% of the readmissions were after 2 weeks. Pneumonia accounted for 32.5% of the readmissions. After readmission, 16.9% of patients were diagnosed with another CCC or received a new TA device, and the in-hospital mortality rate was 6.6%.

Conclusion

The rate of unplanned 30-day readmissions in children with medical complexity in Saudi Arabia is 7.4%, which is lower than those reported from developed countries. Saudi children with CCCs and TA devices were readmitted approximately within similar post-discharge time and showed distinct hospitalization patterns associated with specific diagnoses. To effectively reduce the risk of 30-day readmissions, targeted measures must be introduced both during the hospitalization period and after discharge.

Clinical recommendations for the inpatient management of lower respiratory tract infections in children and adolescents with severe neurological impairment in Germany

Children and adolescents with severe neurological impairment (SNI) require specialized care due to their complex medical needs. In particular, these patients are often affected by severe and recurrent lower respiratory tract infections (LRTIs). These infections, including viral and bacterial etiology, pose a significant risk to these patients, often resulting in respiratory insufficiency and long-term impairments. Using expert consensus, we developed clinical recommendations on the management of LRTIs in children and adolescents with SNI. These recommendations emphasize comprehensive multidisciplinary care and antibiotic stewardship. Initial treatment should involve symptomatic care, including hydration, antipyretics, oxygen therapy, and respiratory support. In bacterial LRTIs, antibiotic therapy is initiated based on the severity of the infection, with aminopenicillin plus a beta-lactamase inhibitor recommended for community-acquired LRTIs and piperacillin-tazobactam for patients with chronic lung disease or tracheostomy. Ongoing management includes regular evaluations, adjustments to antibiotic therapy based on pathogen identification, and optimization of supportive care. Implementation of these recommendations aims to improve the diagnosis and treatment of LRTIs in children and adolescents with SNI. What is Known: • Children and adolescents with severe neurological impairment are particularly affected by severe and recurrent lower respiratory tract infections (LRTIs). • The indication and choice of antibiotic therapy for bacterial LRTI is often difficult because there are no evidence-based treatment recommendations for this heterogeneous but vulnerable patient population; the frequent overuse of broad-spectrum or reserve antibiotics in this patient population increases selection pressure for multidrug-resistant pathogens. What is New: • The proposed recommendations provide a crucial framework for focused diagnostics and treatment of LRTIs in children and adolescents with severe neurological impairment. • Along with recommendations for comprehensive and multidisciplinary therapy and antibiotic stewardship, ethical and palliative care aspects are taken into account.

Current Trends in Invasive Closure of Patent Ductus Arteriosus in Very Low Birth Weight Infants in United States Children's Hospitals, 2016-2021

OBJECTIVE

To describe the current practices in invasive patent ductus arteriosus (PDA) closure (surgical ligation or transcatheter occlusion) in very low birth weight (VLBW) infants and changes in patient characteristics and outcomes from 2016 to 2021 among US children's hospitals.

STUDY DESIGN

We evaluated a retrospective cohort of VLBW infants (birth weight 400-1499 g and gestational age 22-31 weeks) who had invasive PDA closure within 6 months of age from 2016 to 2021 in children's hospitals in the Pediatric Health Information System. Changes in patient characteristics and outcomes over time were evaluated using generalized linear models and generalized linear mixed models.

RESULTS

2418 VLBW infants (1182 surgical ligation; 1236 transcatheter occlusion) from 42 hospitals were included. The proportion of infants receiving transcatheter occlusion increased from 17.2% in 2016 to 84.4% in 2021 (P < .001). In 2021, 28/42 (67%) hospitals had performed transcatheter occlusion in > 80% of their VLBW infants needing invasive PDA closure, compared with only 2/42 (5%) in 2016. Although median postmenstrual age (PMA) at PDA closure did not change for the overall cohort, PMA at transcatheter occlusion decreased from 38 weeks in 2016 to 31 weeks by 2020, P < .001. Among those infants not intubated prior to PDA closure, extubation within 3 days postprocedure increased over time (yearly adjusted odds ratios of 1.26 [1.08-1.48]). Length of stay and mortality did not change over time.

CONCLUSION

We report rapid adoption of transcatheter occlusion for PDA among VLBW infants in US children's hospitals over time. Transcatheter occlusions were performed at younger PMA over time.

Correlation Between Clinical Characteristics and Radionuclide Salivagram Findings in Infants With Congenital Laryngeal Developmental Anomalies

OBJECTIVE

To evaluate the correlation between clinical characteristics and radionuclide salivagram findings in infants with congenital laryngeal developmental anomalies, and determine the clinical characteristics that could predict the positive results of radionuclide salivagram.

METHODS

151 hospitalized infants with congenital laryngeal developmental anomalies were retrospectively included to assess the correlation between positive radionuclide salivagram results and clinical features, and a multivariate logistic regression model was constructed to identify significant correlates that jointly predict positive radionuclide salivagram results.

RESULTS

Positive radionuclide salivagram results were significantly associated with fever, neurological diseases, congenital syndromes, and positive pathogenetic test results in univariate analysis. Positive radionuclide salivagram were significantly associated with fever (odds ratio [OR] = 3.494; 95% confidence interval [CI] 1.414-8.630; P = 0.007), neurological diseases (OR = 3.296; 95% CI 1.335-8.138; P = 0.010), and congenital syndromes (OR = 5.069, 95% CI 1.696-15.154; P = 0.004) in a multivariable logistic regression analysis.

CONCLUSION

Fever, concurrent neurological diseases, and concurrent congenital syndromes were discovered as clinical factors that could predict positive radionuclide salivagram results and salivary aspiration should be highly suspected in infants with these clinical factors of congenital laryngeal developmental anomalies.

Evaluating Adult Idiopathic Scoliosis as an Independent Risk Factor for Critical Illness in SARS-CoV-2 Infection

BACKGROUND

Thoracic spinal deformities may reduce chest wall compliance, leading to respiratory complications. The first SARS-CoV-2 (L-variant) strain caused critical respiratory illness, especially in vulnerable patients. This study investigates the association between scoliosis and SARS-CoV-2 (COVID-19) disease course severity.

METHODS

Clinical data of 129 patients treated between March 2020 to June 2021 who received a positive COVID-19 polymerase chain reaction result from Mount Sinai and had a scoliosis ICD-10 code (M41.0-M41.9) was retrospectively analyzed. Degree of coronal plane scoliosis on imaging was confirmed by 2 independent measurers and grouped into no scoliosis (Cobb angle <10°), mild (10°-24°), moderate (25°-39°), and severe (>40°) cohorts. Baseline characteristics were compared, and a multivariable logistic regression controlling for clinically significant comorbidities examined the significance of scoliosis as an independent risk factor for hospitalization, intensive care unit (ICU) admission, acute respiratory distress syndrome (ARDS), mechanical ventilation, and mortality.

RESULTS

The no (n = 42), mild (n = 14), moderate (n = 44), and severe scoliosis (n = 29) cohorts differed significantly only in age (P = 0.026). The percentage of patients hospitalized (P = 0.59), admitted to the ICU (P = 0.33), developing ARDS (P = 0.77), requiring mechanical ventilation (P = 1.0), or who expired (P = 0.77) did not significantly differ between cohorts. The scoliosis cohorts did not have a significantly higher likelihood of hospital admission (mild P = 0.19, moderate P = 0.67, severe P = 0.98), ICU admission (P = 0.97, P = 0.94, P = 0.22), ARDS (P = 0.87, P = 0.74, P = 0.94), mechanical ventilation (P = 0.73, P = 0.69, P = 0.70), or mortality (P = 0.74, P = 0.87, P = 0.66) than the no scoliosis cohort.

CONCLUSIONS

Scoliosis was not an independent risk factor for critical COVID-19 illness. No trends indicated any consistent effect of degree of scoliosis on increased adverse outcome likelihood.

Eating and Drinking Ability Classification System to detect aspiration risk in children with cerebral palsy: a validation study

This prospective study has two aims. The first aim is to assess the concurrent validity of the Eating and Drinking Ability Classification System (EDACS) as a means of identifying aspiration risk in children with cerebral palsy by using the Pediatric version of the Eating Assessment Tool (PEDI-EAT-10) as the reference test. The second aim is to investigate the relationship between the aspiration and non-aspiration groups using both the EDACS and the PEDI-EAT-10. Data were collected and analyzed from the EDACS and PEDI-EAT-10 using a convenience sample of 131 children with cerebral palsy and feeding problems (77 males, 54 females; median age 4.4 years [IQR 2.5 years]). Risk of aspiration was identified in 118 individuals using the PEDI-EAT-10 scores of ≥ 5 points. The EDACS proved to be a valid tool in identifying aspiration risk in children who are classified in EDACS levels III-V. There was a significant correlation between the EDACS and PEDI-EAT-10 (r_s = 0.597, p < 0.001). The EDACS had 78% (95% CI = 71-86%) sensitivity and 92% (95% CI = 88-97%) specificity in identifying aspiration risk a positive predictive value of 0.99, a negative predictive value of 0.32, a positive likelihood ratio of 9.75, and a negative likelihood ratio of 0.24.   Conclusion: The EDACS is a useful clinical tool to identify aspiration risk in children with cerebral palsy. Children in EDACS levels III to V are at risk of aspiration. As time permits, we recommend the use of both tools, the EDACS and the PEDI-EAT-10, when making decisions regarding referral for an instrumented swallowing study. What is Known: • Approximately 50% of children with cerebral palsy have dysphagia. • The Eating and Drinking Ability Classification System (EDACS) can be used to classify eating and drinking efficiency and safety in children with cerebral palsy. What is New: • Based on ROC analysis, EDACS demonstrates sensitivity of 78% and specificity of 92% in clinical identification of aspiration risk. • The combined use of the EDACS and the Pediatric version of the Eating Assessment Tool is recommended to make decisions about referral for an instrumented swallow study.

Degree of Postoperative Curve Correction Decreases Risks of Postoperative Pneumonia in Patients Undergoing Both Fusion and Growth-friendly Surgical Treatment of Neuromuscular Scoliosis

INTRODUCTION

Due to a combination of poor respiratory muscle control and mechanical lung compression secondary to spine and chest wall deformities, patients with neuromuscular (NM) early-onset scoliosis (EOS) are at a high risk for pulmonary complications including pneumonia. The purpose of this study is to examine the effect of surgical intervention on the prevalence and risk of postoperative pneumonia in patients with NM EOS.

METHODS

In this retrospective cohort study, pediatric (18 y old and below) patients with NM EOS undergoing index fusion or growth-friendly instrumentation from 2000 to 2018 were identified. Patients were then categorized into 2 groups: those with ≥50% curve correction and those with <50% curve correction of the coronal deformity at the first postoperative visit. The primary outcome of interest was postoperative pneumonia occurring between 3 weeks and 2 years postoperatively. Manual chart review was supplemented with phone call surveys to ensure all occurrences of preoperative/postoperative pneumonia (ie, in-institution and out-of-institution visits) were accounted for.

RESULTS

A total of 35 patients (31% female, age at surgery: 10.3±4.3 y) with NM EOS met inclusion criteria. Twenty-three (66%) patients experienced at least 1 case of preoperative pneumonia. Twenty-six (74%) patients had ≥50% and 9 (26%) patients had <50% immediate postoperative curve correction. In total, 12 (34%) patients experienced at least 1 case of postoperative pneumonia (7 in-institution, 5 out-of-institution). Seven (27%) patients with ≥50% curve correction versus 5 (56%) with <50% curve correction experienced postoperative pneumonia. Relative risk regression demonstrated that patients with <50% curve correction had increased risk of postoperative pneumonia by 2.1 times compared with patients with ≥50% curve correction (95% confidence interval: 0.9; 4.9, P =0.099).

CONCLUSION

The prevalence of preoperative and postoperative pneumonia is high in patients with NM EOS. This study presents preliminary evidence suggesting that percent curve correction is associated with the occurrence of postoperative pneumonia in patients with NM EOS undergoing surgical correction.

Associations between comorbidity-related functional limitations and pneumonia outcomes

BACKGROUND

Underlying comorbidities are common in children with pneumonia.

OBJECTIVE

To determine associations between comorbidity-related functional limitations and risk for severe pneumonia outcomes.

DESIGN, SETTING, AND PARTICIPANTS

We prospectively enrolled children <18 years with and without comorbidities presenting to the emergency department with clinical and radiographic pneumonia at two institutions. Comorbidities included chronic conditions requiring daily medications, frequent healthcare visits, or which limited age-appropriate activities. Among children with comorbidities, functional limitations were defined as none or mild, moderate, and severe.

MAIN OUTCOMES AND MEASURES

Outcomes included an ordinal severity outcome, categorized as very severe (mechanical ventilation, shock, or death), severe (intensive care without very severe features), moderate (hospitalization without severe features), or mild (discharged home), and length of stay (LOS). Multivariable ordinal logistic regression was used to examine associations between comorbidity-related functional limitations and outcomes, while accounting for relevant covariates.

RESULTS

A cohort of 1116 children, including 452 (40.5%) with comorbidities; 200 (44.2%) had none or mild functional limitations, 93 (20.6%) moderate, and 159 (35.2%) had severe limitations. In multivariable analysis, comorbidity-related functional limitations were associated with the ordinal severity outcome and LOS (p < .001 for both). Children with severe functional limitations had tripling of the odds of a more severe ordinal (adjusted odds ratio [aOR]: 3.01, 95% confidence interval [2.05, 4.43]) and quadrupling of the odds for longer LOS (aOR: 4.72 [3.33, 6.70]) as compared to children without comorbidities.

CONCLUSION

Comorbidity-related functional limitations are important predictors of disease outcomes in children with pneumonia. Consideration of functional limitations, rather than the presence of comorbidity alone, is critical when assessing risk of severe outcomes.

Evaluation of the Treatment of Aspiration Pneumonia in Hospitalized Children

BACKGROUND

Aspiration pneumonia (AP) treatment is variable with limited available guidance on optimal antibiotic choice and duration. This study evaluated the impact of antibiotic regimen and duration on treatment failure for AP in children and correlated the effects of antimicrobial stewardship program (ASP) interventions on treatment duration.

METHODS

Hospitalized children who received antibiotics for AP were identified through an existing ASP repository. Diagnosis was confirmed through ASP documentation with either an international classification of diseases 9/10 code or physician diagnosis of AP. Incidence of treatment failure (necrotizing pneumonia, lung abscess, empyema, or retreatment) was compared between patients receiving shorter (≤7 days) vs longer (>7 days) course of antibiotics and between various empiric/final antibiotic regimens utilized. Duration of treatment was evaluated in patients with or without an ASP intervention.

RESULTS

Four hundred and nineteen treatment courses for AP were included. Nineteen episodes (4.5%) of treatment failure were identified. No difference in treatment failure was observed between shorter vs longer courses (8 vs 11 episodes). An aminopenicillin plus beta-lactamase inhibitor was most frequently utilized for both empiric (47.2%) and final treatment (67.5%). Treatment failure rates did not differ with length of intravenous therapy nor empiric/final antibiotic regimen chosen. ASP interventions targeting duration were associated with significantly shorter courses (6.28 vs 7.46 days; P = .04).

CONCLUSIONS

Shorter courses of antibiotics did not result in more treatment failure for AP when compared to longer courses. Neither antibiotic choice nor route impacted treatment failure rates. ASPs may optimize the treatment of pediatric AP.

Dysphagia limit in children with cerebral palsy aged 4 to 12 years

AIM

To assess the dysphagia limit in children with cerebral palsy (CP) according to Eating and Drinking Ability Classification System (EDACS) level, sex, and age compared to typically developing children.

METHOD

Seventy-seven children with CP (54 males, 23 females; mean age 7y 6mo, SD 2y 2mo, age range 4-12y) were assessed with the Maximum Volume Water Swallow Test. Median dysphagia limit in the CP group was compared with data of typically developing children.

RESULTS

The dysphagia limit of children with CP differed significantly (p<0.001) from typically developing children. The latter showed a threefold higher median dysphagia limit (22mL) compared to children with CP in EDACS level I (7mL). The higher the EDACS level, the lower the dysphagia limit in children with CP. EDACS level explained 55% of the variance in the dysphagia limit of the CP group.

INTERPRETATION

Where children with CP in EDACS levels IV and V showed that their capacity met the level of their performance, children in EDACS level I had the ability to perform a maximum capacity task, but still had a threefold lower median dysphagia limit than typically developing children. Establishment of the dysphagia limit should be part of general swallowing assessment in children with CP.

Research priorities for children with neurological impairment and medical complexity in high-income countries

AIM

To identify the highest-priority clinical research areas related to children with neurological impairment and medical complexity among clinicians and caregivers.

METHOD

A modified, three-stage Delphi study using online surveys and guided by a steering committee was completed. In round 1, clinicians and family caregivers suggested clinical topics and related questions that require research to support this subgroup of children. After refinement of the suggestions by the steering committee, participants contributed to 1 (family caregivers) or 2 (clinicians) subsequent rounds to develop a prioritized list.

RESULTS

A diverse international expert panel consisting of 49 clinicians and 12 family caregivers provided 601 responses. Responses were distilled into 26 clinical topics comprising 126 related questions. The top clinical topics prioritized for research were irritability and pain, child mental health, disorders of tone, polypharmacy, sleep, aspiration, behavior, dysautonomia, and feeding intolerance. The clinician expert panel also prioritized 10 specific research questions.

INTERPRETATION

Study findings support a research agenda for children with neurological impairment and medical complexity focused on addressing clinical questions, prioritized by an international group of clinicians and caregivers.

Variation in Bacterial Respiratory Culture Results in Children With Neurologic Impairment

OBJECTIVES

To examine bacterial respiratory cultures in children with neurologic impairment (NI) (eg, cerebral palsy), both with and without tracheostomies, who were hospitalized with acute respiratory infections (ARIs) (eg, pneumonia) and to compare culture results across hospitals and age groups.

METHODS

This multicenter retrospective cohort study included ARI hospitalizations for children aged 1 to 18 years with NI between 2007 and 2012 who had a bacterial respiratory culture obtained within 2 days of admission. Data from 5 children's hospitals in the Pediatric Health Information System Plus database were used. Organisms consistent with oral flora and nonspeciated organisms were omitted from analysis. The prevalence of positive respiratory culture results and the prevalence of organisms identified were compared across hospitals and age groups and in subanalyses of children with and without tracheostomies by using generalized estimating equations to account for within-patient clustering.

RESULTS

Of 4900 hospitalizations, 693 from 485 children had bacterial respiratory cultures obtained. Of these, 54.5% had positive results, although this varied across hospitals (range 18.6%-83.2%; P < .001). Pseudomonas aeruginosa and Staphylococcus aureus were the most commonly identified organisms across hospitals and age groups and in patients with and without tracheostomies. Large variation in growth prevalence was identified across hospitals but not age groups.

CONCLUSIONS

The bacteriology of ARI in hospitalized children with NI differs from that of otherwise healthy children. Significant variation in prevalence of positive bacterial respiratory culture results and organism growth were observed across hospitals, which may be secondary to local environmental factors and microbiology reporting practices.

Readmissions Following Hospitalization for Infection in Children With or Without Medical Complexity

OBJECTIVE

To describe the prevalence and characteristics of infection-related readmissions in children and to identify opportunities for readmission reduction and estimate associated cost savings.

STUDY DESIGN

Retrospective analysis of 380,067 nationally representative index hospitalizations for children using the 2014 Nationwide Readmissions Database. We compared 30-day, all-cause unplanned readmissions and costs across 22 infection categories. We used the Inpatient Essentials database to measure hospital-level readmission rates and to establish readmission benchmarks for individual infections. We then estimated the number of readmissions avoided and costs saved if hospitals achieved the 10th percentile of hospitals' readmission rates (ie, readmission benchmark). All analyses were stratified by the presence/absence of a complex chronic condition (CCC).

RESULTS

The overall 30-day readmission rate was 4.9%. Readmission rates varied substantially across infections and by presence/absence of a CCC (CCC: range, 0%-21.6%; no CCC: range, 1.5%-8.6%). Approximately 42.6% of readmissions (n = 3,576) for children with a CCC and 54.7% of readmissions (n = 5,507) for children without a CCC could have been potentially avoided if hospitals achieved infection-specific benchmark readmission rates, which could result in an estimated savings of $70.8 million and $44.5 million, respectively. Bronchiolitis, pneumonia, and upper respiratory tract infections were among infections with the greatest number of potentially avoidable readmissions and cost savings for children with and without a CCC.

CONCLUSION

Readmissions following hospitalizations for infection in children vary significantly by infection type. To improve hospital resource use for infections, future preventative measures may prioritize children with complex chronic conditions and those with specific diagnoses (eg, respiratory illnesses).

Timing of Co-occurring Chronic Conditions in Children With Neurologic Impairment

BACKGROUND

Children with neurologic impairment (NI) are at risk for developing co-occurring chronic conditions, increasing their medical complexity and morbidity. We assessed the prevalence and timing of onset for those conditions in children with NI.

METHODS

This longitudinal analysis included 6229 children born in 2009 and continuously enrolled in Medicaid through 2015 with a diagnosis of NI by age 3 in the IBM Watson Medicaid MarketScan Database. NI was defined with an existing diagnostic code set encompassing neurologic, genetic, and metabolic conditions that result in substantial functional impairments requiring subspecialty medical care. The prevalence and timing of co-occurring chronic conditions was assessed with the Agency for Healthcare Research and Quality Chronic Condition Indicator system. Mean cumulative function was used to measure age trends in multimorbidity.

RESULTS

The most common type of NI was static (56.3%), with cerebral palsy (10.0%) being the most common NI diagnosis. Respiratory (86.5%) and digestive (49.4%) organ systems were most frequently affected by co-occurring chronic conditions. By ages 2, 4, and 6 years, the mean (95% confidence interval [CI]) numbers of co-occurring chronic conditions were 3.7 (95% CI 3.7-3.8), 4.6 (95% CI 4.5-4.7), and 5.1 (95% CI 5.1-5.2). An increasing percentage of children had ≥9 co-occurring chronic conditions as they aged: 5.3% by 2 years, 10.0% by 4 years, and 12.8% by 6 years.

CONCLUSIONS

Children with NI enrolled in Medicaid have substantial multimorbidity that develops early in life. Increased attention to the timing and types of multimorbidity in children with NI may help optimize their preventive care and case management health services.

Aspiration pneumonia after antireflux surgery among neurologically impaired children with GERD

BACKGROUND AND OBJECTIVE

Aspiration pneumonia is a common and serious complication to gastroesophageal reflux disease (GERD) among neurologically impaired children. Medication of GERD does not effectively prevent aspiration pneumonia, and whether antireflux surgery with fundoplication is better in this respect is uncertain. The objective was to determine whether fundoplication prevents aspiration pneumonia among children with neurological impairment and GERD.

METHODS

This was a population-based cohort study from Denmark, Finland, Norway and Sweden, consisting of neurologically impaired children with GERD who underwent fundoplication. The risk of aspiration pneumonia before fundoplication (preoperative person-time) was compared with the risk after surgery (postoperative person-time). Multivariable Cox regression provided hazard ratios (HRs) with 95% confidence intervals (CIs). Except for confounding adjusted for by means of the "crossover like" design, the HRs were adjusted for age, sex, year of entry and respiratory diseases.

RESULTS

Among 578 patients (median age 3.5 years), the preoperative person-time was 956 years and the postoperative person-time was 3324 years. Fundoplication was associated with 56% decreased overall HR of aspiration pneumonia (HR 0.44, 95% CI 0.27-0.72), and the HRs decreased over time after surgery. The risk of other types of pneumonia than aspiration pneumonia was not clearly decreased after fundoplication (HR 0.79, 95% CI 0.59-1.08). The 30-day mortality rate was 0.7% and the complication rate was 3.6%.

CONCLUSIONS

Antireflux surgery decreases, but does not eliminate, the risk of aspiration pneumonia among neurologically impaired children with GERD. Fundoplication may be a treatment option when aspiration pneumonia is a recurrent problem in these children.

Antibiotic exposure in hospitalized pediatric patients in the United States: prevalence and length of stay

BACKGROUND

Hospital antibiotic use is rising. We aimed to evaluate the antibiotic-use prevalence and length of stay.

METHODS

We conducted a single-center retrospective study of patients < 18-years-old admitted to general pediatric services who received ≥ 1 antibiotic over six months. Demographics, culture results and antibiotic details were collected. The primary outcome was to identify the total number and classes of antibiotics prescribed during the admission. Secondary outcomes included length of stay (LOS), culture results, and the most commonly used antibiotics.

RESULTS

Forty-eight percent of patients received monotherapy (single class antibiotic). Cephalosporins (55%), vancomycin (35%), and clindamycin (22%) were prescribed more commonly than other antibiotic classes. Children were exposed up to 4 classes of antibiotics (range 1-4). A moderate correlation existed between the length of stay and the number of antibiotic classes used (R² = 0.38). Two or more classes of antibiotic use prolonged the length of stay. Cephalosporin use was associated with 35% reduced LOS (95 CI, 21%-57%), and penicillin use correlated with 38% more prolonged LOS (95 CI, 22%-66%).

CONCLUSIONS

Antibiotic use in pediatric hospitals was high, and children received multiple classes of antibiotics. Inappropriate antibiotic use and culture results may have an untoward effect on hospital length of stay.

Antibiotics for Aspiration Pneumonia in Neurologically Impaired Children

OBJECTIVE

To compare hospital outcomes associated with commonly used antibiotic therapies for aspiration pneumonia in children with neurologic impairment (NI).

DESIGN/METHODS

A retrospective study of children with NI hospitalized with aspiration pneumonia at 39 children's hospitals in the Pediatric Health Information System database. Exposure was empiric antibiotic therapy classified by antimicrobial activity. Outcomes included acute respiratory failure, intensive care unit (ICU) transfer, and hospital length of stay (LOS). Multivariable regression evaluated associations between exposure and outcomes and adjusted for confounders, including medical complexity and acute illness severity.

RESULTS

In the adjusted analysis, children receiving Gram-negative coverage alone had two-fold greater odds of respiratory failure (odds ratio [OR] 2.15; 95% CI: 1.41-3.27), greater odds of ICU transfer (OR 1.80; 95% CI: 1.03-3.14), and longer LOS [adjusted rate ratio (RR) 1.28; 95% CI: 1.16-1.41] than those receiving anaerobic coverage alone. Children receiving anaerobic and Gram-negative coverage had higher odds of respiratory failure (OR 1.65; 95% CI: 1.19-2.28) than those receiving anaerobic coverage alone, but ICU transfer (OR 1.15; 95% CI: 0.73-1.80) and length of stay (RR 1.07; 95% CI: 0.98-1.16) did not statistically differ. For children receiving anaerobic, Gram-negative, and P. aeruginosa coverage, LOS was shorter (RR 0.83; 95% CI: 0.76-0.90) than those receiving anaerobic coverage alone; odds of respiratory failure and ICU transfer rates did not significantly differ.

CONCLUSIONS

Anaerobic therapy appears to be important in the treatment of aspiration pneumonia in children with NI. While Gram-negative coverage alone was associated with worse outcomes, its addition to anaerobic therapy may not yield improved outcomes.

Non-ventilator health care-associated pneumonia (NV-HAP): Pediatrics

There is a paucity of data on the prevalence, risk factors or prevention of nonventilator health care-associated pneumonia (NV-HAP) in children. As with adults, viral, fungal and bacterial infections can lead to NV-HAP, but surveillance definitions and case ascertainment remain a challenge. This section will review the known epidemiology of NV-HAP in the pediatric population, risk factors, surveillance, and prevention practices. Prevention strategies specific to pediatrics, aimed at reducing risk of viral transmission to hospitalized children will be discussed.

Biochemical and structural insights into the cytochrome P450 reductase from Candida tropicalis

Cytochrome P450 reductases (CPRs) are diflavin oxidoreductases that supply electrons to type II cytochrome P450 monooxygenases (CYPs). In addition, it can also reduce other proteins and molecules, including cytochrome c, ferricyanide, and different drugs. Although various CPRs have been functionally and structurally characterized, the overall mechanism and its interaction with different redox acceptors remain elusive. One of the main problems regarding electron transfer between CPRs and CYPs is the so-called "uncoupling", whereby NAD(P)H derived electrons are lost due to the reduced intermediates' (FAD and FMN of CPR) interaction with molecular oxygen. Additionally, the decay of the iron-oxygen complex of the CYP can also contribute to loss of reducing equivalents during an unproductive reaction cycle. This phenomenon generates reactive oxygen species (ROS), leading to an inefficient reaction. Here, we present the study of the CPR from Candida tropicalis (CtCPR) lacking the hydrophobic N-terminal part (Δ2-22). The enzyme supports the reduction of cytochrome c and ferricyanide, with an estimated 30% uncoupling during the reactions with cytochrome c. The ROS produced was not influenced by different physicochemical conditions (ionic strength, pH, temperature). The X-ray structures of the enzyme were solved with and without its cofactor, NADPH. Both CtCPR structures exhibited the closed conformation. Comparison with the different solved structures revealed an intricate ionic network responsible for the regulation of the open/closed movement of CtCPR.

Association of Proton Pump Inhibitors With Hospitalization Risk in Children With Oropharyngeal Dysphagia

Importance

Proton pump inhibitors (PPI) are commonly prescribed to children with oropharyngeal dysphagia and resultant aspiration based on the assumption that these patients are at greater risk for reflux-related lung disease. There is little data to support this approach and the potential risk for increased infections in children treated with PPI may outweigh any potential benefit.

Objective

The aim of this study was to determine if there is an association between hospitalization risk in pediatric patients with oropharyngeal dysphagia and treatment with PPI.

Design, Setting, and Participants

We performed a retrospective cohort study to compare the frequency and length of hospitalizations for children who had abnormal results on videofluoroscopic swallow studies that were performed between January 1, 2015, and December 31, 2015, and who were or were not treated with PPI, with follow-up through December 31, 2016. Records were reviewed for children who presented for care at Boston Children's Hospital, a tertiary referral center. Participants included 293 children 2 years and younger with evidence of aspiration or penetration on videofluoroscopic swallow study.

Exposures

Groups were compared based on their exposure to PPI treatment.

Main Outcomes and Measures

The primary outcomes were hospital admission rate and hospital admission nights and these were measured as incident rates. Multivariable analyses were performed to determine predictors of hospitalization risk after adjusting for comorbidities. Kaplan-Meier curves were created to determine the association of PPI prescribing with time until first hospitalization.

Results

A total of 293 patients with a mean (SD) age of 8.8 (0.4) months and a mean (SD) follow-up time of 18.15 (0.20) months were included in the analysis. Patients treated with PPI had higher admission rates (Incidence rate ratio [IRR], 1.77; 95% CI, 1.16-2.68) and admission nights (IRR, 2.51; 95% CI, 1.36-4.62) even after adjustment for comorbidities. Patients with enteral tubes who were prescribed PPIs were at the highest risk for admission (hazard ratio [HR], 2.31; 95% CI, 1.24-4.31).

Conclusions and Relevance

Children with aspiration who are treated with PPI have increased risk of hospitalization compared with untreated patients. These results support growing concern about the risks of PPI use in children.

Aerodigestive sampling reveals altered microbial exchange between lung, oropharyngeal, and gastric microbiomes in children with impaired swallow function

BACKGROUND

Children with oropharyngeal dysphagia have impaired airway protection mechanisms and are at higher risk for pneumonia and other pulmonary complications. Aspiration of gastric contents is often implicated as a cause for these pulmonary complications, despite being supported by little evidence. The goal of this study is to determine the relative contribution of oropharyngeal and gastric microbial communities to perturbations in the lung microbiome of children with and without oropharyngeal dysphagia and aspiration.

METHODS

We conducted a prospective cohort study of 220 patients consecutively recruited from a tertiary aerodigestive center undergoing simultaneous esophagogastroduodenoscopy and flexible bronchoscopy. Bronchoalveolar lavage, gastric and oropharyngeal samples were collected from all recruited patients and 16S sequencing was performed. A subset of 104 patients also underwent video fluoroscopic swallow studies to assess swallow function and were categorized as aspiration/no aspiration. To ensure the validity of the results, we compared the microbiome of these aerodigestive patients to the microbiome of pediatric patients recruited to a longitudinal cohort study of children with suspected GERD; patients recruited to this study had oropharyngeal, gastric and/or stool samples available. The relationships between microbial communities across the aerodigestive tract were described by analyzing within- and between-patient beta diversities and identifying taxa which are exchanged between aerodigestive sites within patients. These relationships were then compared in patients with and without aspiration to evaluate the effect of aspiration on the aerodigestive microbiome.

RESULTS

Within all patients, lung, oropharyngeal and gastric microbiomes overlap. The degree of similarity is the lowest between the oropharynx and lungs (median Jensen-Shannon distance (JSD) = 0.90), and as high between the stomach and lungs as between the oropharynx and stomach (median JSD = 0.56 for both; p = 0.6). Unlike the oropharyngeal microbiome, lung and gastric communities are highly variable across people and driven primarily by person rather than body site. In patients with aspiration, the lung microbiome more closely resembles oropharyngeal rather than gastric communities and there is greater prevalence of microbial exchange between the lung and oropharynx than between gastric and lung sites (p = 0.04 and 4x10-5, respectively).

CONCLUSIONS

The gastric and lung microbiomes display significant overlap in patients with intact airway protective mechanisms while the lung and oropharynx remain distinct. In patients with impaired swallow function and aspiration, the lung microbiome shifts towards oropharyngeal rather than gastric communities. This finding may explain why antireflux surgeries fail to show benefit in pediatric pulmonary outcomes.

Impact of stroke-associated pneumonia on mortality, length of hospitalization, and functional outcome

OBJECTIVES

Stroke-associated pneumonia (SAP) is common and associated with adverse outcomes. Data on its impact beyond 1 year are scarce.

MATERIALS AND METHODS

This observational study was conducted in a cohort of stroke patients admitted consecutively to a tertiary referral center in the east of England, UK (January 2003-April 2015). Logistic regression models examined inpatient mortality and length of stay (LOS). Cox regression models examined longer-term mortality at predefined time periods (0-90 days, 90 days-1 year, 1-3 years, and 3-10 years) for SAP. Effect of SAP on functional outcome at discharge was assessed using logistic regression.

RESULTS

A total of 9238 patients (mean age [±SD] 77.61 ± 11.88 years) were included. SAP was diagnosed in 1083 (11.7%) patients. The majority of these cases (n = 658; 60.8%) were aspiration pneumonia. After controlling for age, sex, stroke type, Oxfordshire Community Stroke Project (OCSP) classification, prestroke modified Rankin scale, comorbidities, and acute illness markers, mortality estimates remained significant at 3 time periods: inpatient (OR 5.87, 95%CI [4.97-6.93]), 0-90 days (2.17 [1.97-2.40]), and 91-365 days (HR 1.31 [1.03-1.67]). SAP was also associated with higher odds of long LOS (OR 1.93 [1.67-2.22]) and worse functional outcome (OR 7.17 [5.44-9.45]). In this cohort, SAP did not increase mortality risk beyond 1 year post-stroke, but it was associated with reduced mortality beyond 3 years.

CONCLUSIONS

Stroke-associated pneumonia is not associated with increased long-term mortality, but it is linked with increased mortality up to 1 year, prolonged LOS, and poor functional outcome on discharge. Targeted intervention strategies are required to improve outcomes of SAP patients who survive to hospital discharge.

Risk factors for hospitalizations due to bacterial respiratory tract infections after tracheotomy

OBJECTIVE

Identify characteristics associated with hospital readmission due to bacterial respiratory tract infections (bRTI) after tracheotomy.

STUDY DESIGN

Retrospective study of 8009 children 0-17 years undergoing tracheotomy from 2007 to 2013 at 48 children's hospitals in the Pediatric Health Information System database. The primary outcome was first hospital admission after tracheotomy for bRTI (ie, primary diagnosis of bRTI or a primary diagnosis of bRTI symptom and secondary diagnosis of bRTI). We used Cox-proportional hazard modeling to assess associations between patient demographic and clinical characteristics and bRTI hospital readmission.

RESULTS

Median age at tracheotomy admission was 5 months (interquartile range [IQR]: 1-50 months). Thirty-six percent (n = 2899) had at least one bRTI admission. Median time-to-readmission for bRTI was 275 days (IQR: 141-530). Factors independently associated with increased risk for bRTI readmission were younger age (eg, age < 30 days vs 13-17 years [aHR 1.32; 95%CI: 1.11-1.58]), Hispanic race/ethnicity (vs non-Hispanic White; aHR: 1.34; 95%CI: 1.20-1.50), government insurance (vs private; aHR 1.21; 95%CI: 1.10-1.33), >2 complex chronic conditions (vs zero; aHR 1.96; 95%CI: 1.34-2.86) and discharge to home (vs post-acute care setting; aHR 1.19; 95%CI: 1.08-1.32). Trauma diagnosis at tracheotomy (aHR 0.83; 95%CI: 0.69-1) and ventilator dependency (aHR 0.88; 95%CI: 0.81-0.97) were associated with decreased risk.

CONCLUSIONS

Young, Hispanic children with multiple complex chronic conditions who use Medicaid insurance and are not discharged to post-acute care are at the highest risk for hospital readmission for bRTI post-tracheotomy. Future research should investigate strategies to mitigate this risk for these children.

Length of Stay and Hospital Revisit After Bacterial Tracheostomy-Associated Respiratory Tract Infection Hospitalizations

OBJECTIVES

To identify factors associated with longer length of stay (LOS) and higher 30-day hospital revisit rates for children hospitalized with bacterial tracheostomy-associated respiratory tract infections (bTARTIs).

METHODS

This was a multicenter, retrospective cohort study using administrative data from the Pediatric Health Information System database between 2007 and 2014 of patients 30 days to 17 years old with a principal discharge diagnosis of bTARTI or a principal discharge diagnosis of bTARTI symptoms with a secondary diagnosis of bTARTI. Primary outcomes of LOS (in days) and 30-day all-cause revisit rates (inpatient, observation, or emergency department visit) were analyzed by using a 3-level hierarchical regression model (discharges within patients within hospital).

RESULTS

We included 3715 unique patients and 7355 discharges. The median LOS was 4 days (interquartile range: 3-8 days), and the 30-day revisit rate was 30.5%. Compared with children 1 to 4 years old, children aged 30 days to 12 months had both longer LOS (adjusted length of stay [aLOS] = +0.9 days; 95% confidence interval [CI]: 0.6 to 1.3) and increased hospital revisit risk (adjusted odds ratio [aOR] = 1.5; 95% CI: 1.3 to 1.7). Other factors associated with longer LOS included public insurance (aLOS = +0.5 days; 95% CI: 0.2 to 0.8), 3 or more complex chronic conditions (CCCs), mechanical ventilation (acute or chronic), and empirical anti-Pseudomonas aeruginosa antibiotics (aLOS = +0.6 days; 95% CI: 0.3 to 0.9). Other factors associated with 30-day revisit included 4 or more CCCs (aOR = 1.3; 95% CI: 1.1 to 1.6) and chronic ventilator dependency (aOR = 1.1; 95% CI: 1.0 to 1.3).

CONCLUSIONS

Ventilator-dependent patients <12 months old with at least 4 CCCs are at highest risk for both longer LOS and 30-day revisit after discharge for bTARTIs. They may benefit from bTARTI prevention strategies and intensive care coordination while hospitalized.

Use of Post-Acute Facility Care in Children Hospitalized With Acute Respiratory Illness

BACKGROUND

Recovery from respiratory illness (RI), a common reason for hospitalization, can be protracted for some children because of high illness severity or underlying medical complexity.

OBJECTIVE

We assessed which children hospitalized with RI are the most likely to use post-acute facility care (PAC) for recovery.

METHODS

Retrospective analysis of 609,800 hospitalizations for patients in 43 US children's hospitals between 2010- 2015 for RI, identified with the Agency for Healthcare Research and Quality Clinical Classification System. Discharge to PAC was identified using Centers for Medicare & Medicaid Services Discharge Status Codes. We compared patient characteristics by PAC use with generalized estimating equations.

RESULTS

There were 2660 (0.4%) RI hospitalizations resulting in PAC transfer (n = 2660, 0.4%). Discharges to PAC had greater percentages of technology assistance (83.2% vs 15.1%), neuromuscular chronic condition (57.5% vs 8.9%), and mechanical ventilation (52.7% vs 9.1%), 𝑃 < 0.001 for all. The highest likelihood of PAC use occurred with ≥11 vs no chronic conditions (odds ratio [OR] 11.7 [95% CI, 8.0- 17.2]), ≥9 vs no therapeutic medication classes (OR 4.8 [95% CI, 1.8-13.0]), and existing tracheostomy (OR 3.0, 95% confidence interval [CI], 2.6-3.5). Median (interquartile range [IQR]) acute-care length of stay (LOS) for children most likely to use PAC was 19 (8-56) days; LOS remained long (median 13 [6-41] days) for children with the same attributes (n = 9448) not transferred to PAC.

CONCLUSIONS

Children with RI who are most likely to use PAC have a high prevalence of multiple chronic conditions, multiple medications, and medical technology. Future investigations should assess the supply of PAC against the demand of hospitalized children with RI who might need it.

Diagnostic Testing and Hospital Outcomes of Children with Neurologic Impairment and Bacterial Pneumonia

OBJECTIVE

To assess hospital-level variability in diagnostic testing and outcomes for children with neurologic impairment hospitalized with pneumonia.

STUDY DESIGN

A retrospective cohort study of 27 455 children ages 1-18 years with neurologic impairment hospitalized with pneumonia at 39 children's hospitals. K-means clustering was used to assign each hospital to 1 of 3 groups (termed A, B, and C) based on similar diagnostic testing patterns. Outcomes of hospital-level median length of stay (LOS), 30-day readmissions, and pneumonia-associated complications were compared while controlling for patient differences.

RESULTS

Overall, 48.5% had comorbid complex chronic conditions, and 25.4% were assisted with medical technology. Outcomes and diagnostic testing varied across hospitals: median hospital-level LOS, 3.2 days (IQR 2.8-3.8); median readmission, 8.4% (IQR 6.8,-10.0); and median pneumonia-associated complication rate, 23.1% (IQR 18.7-26.8). Despite similar populations, hospitals in group A tended to perform fewer tests than those in groups B and C. Across hospital groups, there was a significant difference in adjusted readmission rates (group A 7.2%, group B 9.0%, group C 7.7%, P = .003). There was no significant difference in adjusted median LOS (group A 3.4 days, group B 3.2 days, group C 3.3 days, P = .3) or adjusted pneumonia-associated complication rates (group A 22.5%, group B 22.5%, group C 25.0%, P = .6).

CONCLUSIONS

For children with neurologic impairment hospitalized with pneumonia, across hospital differences in diagnostic testing were not associated with clinically meaningful differences in outcomes. High-utilizing hospitals may be able to decrease diagnostic testing for children with neurologic impairment hospitalized with pneumonia without adversely impacting outcomes.

Characteristics of Children Hospitalized With Aspiration Pneumonia

OBJECTIVES

Unlike community-acquired pneumonia (CAP), there is a paucity of data characterizing the patient demographics and hospitalization characteristics of children with aspiration pneumonia. We used a large national database of US children's hospitals to assess the patient and hospitalization characteristics associated with aspiration pneumonia and compared these characteristics to patients with CAP.

METHODS

We identified children hospitalized with a diagnosis of aspiration pneumonia or CAP at 47 hospitals included in the Pediatric Health Information System between 2009 and 2014. We evaluated whether differences exist in patient characteristics (median age and proportion of patients with a complex chronic condition), and hospital characteristics (length of stay, ICU admission, cost, and 30-day readmission rate) between children with aspiration pneumonia and CAP. Lastly, we assessed whether seasonal variability exists within these 2 conditions.

RESULTS

Over the 6-year study period, there were 12 097 children hospitalized with aspiration pneumonia, and 121 489 with CAP. Compared with children with CAP, children with aspiration pneumonia were slightly younger and more likely to have an associated complex chronic condition. Those with aspiration pneumonia had longer hospitalizations, higher rates of ICU admission, and higher 30-day readmission rates. Additionally, the median cost for hospitalization was 2.4 times higher for children with aspiration pneumonia than for children with CAP. More seasonal variation was observed for CAP compared with aspiration pneumonia hospitalizations.

CONCLUSIONS

Aspiration pneumonia preferentially affects children with medical complexity and, as such, accounts for longer and more costly hospitalizations and higher rates of ICU admission and readmission rates.
