Effect modifiers of the association of high-flow nasal cannula and bronchiolitis length of stay.
In hospitalized children with bronchiolitis, the use of High-flow nasal cannula (HFNC) therapy is related with a longer length of stay (LOS) when used outside of the ICU. The purpose of this study was to explore the relationship between HFNC and LOS to determine if demographic and clinical factors modify the effect of HFNC usage on LOS. Of 8,060 included patients, 27.0% received HFNC during admission. The study found that age group, weight, complex chronic condition, initial tachypnea, initial desaturation, and ICU services were significantly related with LOS. The effect of HFNC on LOS varied among hospitals (P < .001), with the estimated increase in LOS ranging from 32% to 139%. 1- to 6-month-old infants, patients without initial desaturation, and patients without ICU services had the highest relationship between HFNC and LOS, respectively.

Respiratory syncytial virus, influenza, and coronavirus disease 2019 hospitalizations in children in Colorado during the 2021-2022 respiratory virus season.
This study compared demographic characteristics, clinical features, and outcomes of children hospitalized with respiratory syncytial virus (RSV), influenza, or severe acute respiratory syndrome coronavirus 2 during their cocirculation 2021-2022 respiratory virus season. The authors conducted a retrospective cohort study using Colorado's hospital respiratory surveillance data comparing coronavirus disease 2019 (COVID-19)-, influenza-, and RSV-hospitalized cases < 18 years of age admitted and undergoing standardized molecular testing between October 1, 2021, and April 30, 2022. The cohort consisted of 847 hospitalized cases, of which 490 (57.9%) were RSV associated, 306 (36.1%) were COVID-19 associated, and 51 (6%) were influenza associated. Most RSV cases were children less than 4 years of age (92.9%), whereas influenza hospitalizations were observed in older children. RSV cases were more likely to require oxygen support higher than nasal cannula compared with COVID-19 and influenza cases, although COVID-19 cases were more likely to require invasive mechanical ventilation than influenza and RSV cases. Compared with children with COVID-19, the risk of intensive care unit admission was highest among children with influenza, whereas the risk of pneumonia, bronchiolitis, longer hospital length of stay, and need for oxygen were more likely among children with RSV.

Association of Early Physician Follow-up With Readmission Among Patients Hospitalized for Acute Myocardial Infarction, Congestive Heart Failure, or Chronic Obstructive Pulmonary Disease.
Investigators assessed whether hospitalized patients with early physician follow-up after discharge had lower rates of overall and condition-specific readmissions within 30 days and 90 days of discharge. Studying adults in Ontario, Canada, with first admission for acute myocardial infarction, congestive heart failure, or chronic obstructive pulmonary disease, the findings suggested that early follow-up in conjunction with a comprehensive transitional care strategy for hospitalized patients with medically complex conditions coupled with ongoing effective chronic disease management may be associated with reduced 90-day readmissions.

Severity of hospitalizations from SARS-CoV-2 vs influenza and respiratory syncytial virus infection in children aged 5 to 11 years in 11 US states.
By the time emergency use authorization had been granted for the Pfizer-BioNTech vaccine in October 2021 in children aged 5 to 11 years, there had been 1.8 million diagnoses of SARS-CoV-2 infection, 8,000 hospitalizations, and 143 deaths in that age group. Very little has been reported on the severity of those hospitalizations relative to the influenza virus and respiratory syncytial virus (RSV) which are the most common childhood viruses. The purpose of this study was to compare hospitalizations of children aged 5 to 11 for SARS-CoV-2 infection and multisystem inflammatory system in children (MIS-C, a sequela of COVID-19 disease) with the hospitalizations of children aged 5 to 11 years who were infected with influenza and RSV. The researchers utilized inpatient data from the Agency for Healthcare Research and Quality (AHRQ) Healthcare Cost and Utilization Project from the first 11 states with complete first-quarter data as of October 2021, representing 24% of the US population of children aged 5 to 11 years. The researchers examined 46 complications in 7 body systems, total care costs and charges, and data on race and ethnicity. The resulting cross-sectional study included patient data from a total of 2,269 children. The study found that COVID-19 hospitalizations occurred at the rate of 10.8 per 100,000 children, while Influenza and RSV were rare during the first quarter of 2021 with 23 total hospital discharges combined. However, in 2017, which researchers also measured for data on influenza and RSV, influenza and RSV had 17.0 and 6.2 hospitalizations per 100,000 children, respectively. Inpatient death for all viruses was rare. MIS-C had the highest rates of cardiovascular, hematologic, and gastrointestinal complications. Children with RSV ha the highest rate of respiratory complications. Children with COVID-19 (without MISC-C) had the highest rate of neurologic complications, whereas children with influenza had the highest rate of muscoskeletal complications. Children with MIS-C had the longest median length of stay at a median cost of $23,585 per stay compared to children with influenza with a median length of stay of 2 days and a cost of $5,200.

CPAP adherence is associated with reduced inpatient utilization among older adult Medicare beneficiaries with pre-existing cardiovascular disease.
The purpose of this study was to examine the impact of adherence to continuous positive airway pressure (CPAP) therapy on health care utilization among a nationally representative and sample of older adults with multiple morbidities and pre-existing cardiovascular disease and subsequently diagnosed with obstructive sleep apnea in the United States. The investigators concluded that in this nationally representative sample of older Medicare beneficiaries with multiple morbidities and relative to low adherers, high adherers demonstrated reduced inpatient utilization.

Which nursing home residents with pneumonia are managed on-site and which are hospitalized? Results from 2 years' surveillance in 14 US homes.
Pneumonia is a frequent cause of hospitalization among nursing home (NH) residents, but little information is available as to how clinical presentation and other characteristics relate to hospitalization, and the differential use of antimicrobials based on hospitalization status. This study examined how hospitalized and nonhospitalized NH residents with pneumonia differ. The investigators concluded that respiratory rate was associated with hospitalization but was not documented for more than a quarter of residents.

Evaluation of an educational outreach and audit and feedback program to reduce continuous pulse oximetry use in hospitalized infants with stable bronchiolitis: a nonrandomized clinical trial.
National guidelines recommend against continuous pulse oximetry use for hospitalized children with bronchiolitis who are not receiving supplemental oxygen, yet guideline-discordant use remains high. The objective of this study was to evaluate deimplementation outcomes of educational outreach and audit and feedback strategies aiming to reduce guideline-discordant continuous pulse oximetry use in children hospitalized with bronchiolitis who are not receiving supplemental oxygen.

Readmissions reduction program: mortality and readmissions for chronic obstructive pulmonary disease.
Implementation of the Hospital Readmissions Reduction Program (HRRP) following discharge of patients with chronic obstructive pulmonary disease (COPD) has led to a reduction in 30-day readmissions with unknown effects on postdischarge mortality. The objective of this retrospective cohort study was to examine the association of HRRP with 30-day hospital readmission and 30-day postdischarge mortality rate in patients after discharge from COPD hospitalization.

Steroid variability in pediatric inpatient asthmatics: survey on provider preferences of dexamethasone versus prednisone.
This study looked at pediatric emergency department (ED) inpatient use of dexamethasone versus prednisone by providers for asthma treatment. A survey was distributed to providers who care for inpatient asthmatics. Ninety-two providers completed the survey. When patients received dexamethasone in the ED, 44% continued dexamethasone, 14% switched to prednisone, 2% stopped steroid use, and 40% said it depended on the circumstances. Hospitalists were significantly more likely to continue dexamethasone than pulmonologists (61% versus 15%). Switching to prednisone included factors such as severity of exacerbation (73%) and asthma history (47%). Just over half of providers (5f1%) felt uncomfortable using dexamethasone because of “minimal data to support [its] use inpatient.”

Pathways for improving inpatient pediatric asthma care (PIPA): a multicenter, national study.
This study examined whether implementation of a pathway strategy for inpatient pediatric asthma patients improve outcomes for these patients. Outcomes measured included length of stay (LOS), early administration of metered-dose inhalers, screening for secondhand tobacco exposure and referral to cessation resources, and 7-day hospital readmissions or emergency revisits. Eighty-five hospitals were enrolled and 68 completed the study with (n=12,013) admissions. Pathways were associated with increases in early administration of metered-dose inhalers, and referral to smoking cessation resources, but no statistically significant changes in the other outcomes were observed. Most hospitals did improve in at least one outcome.

Contribution of social factors to readmissions within 30 days after hospitalization for COPD exacerbation.
This study examined whether adding social factors improved the predictive ability for 30-day hospital readmissions for COPD. Social factors include educational level and marital status. Out of 905 hospitalizations identified in the Medicare Current Beneficiary Survey from 2006 through 2012, 18.5% were readmitted within 30 days. The optimized model including social factors for prediction improved for early readmissions but not for late readmissions.

Prevalence of continuous pulse oximetry monitoring in hospitalized children with bronchiolitis not requiring supplemental oxygen.
This study examined the use of continuous pulse oximetry monitoring in hospitalized children with bronchiolitis who do not require supplemental oxygen. US national guidelines discourage the use but the practice was found to be still fairly widespread. The researchers conducted a multicenter, cross-sectional study of pediatric wards in 56 US and Canadian hospitals in the Pediatric Research in Inpatient Settings Network from December 2018 through March 2019. Patients aged 8 weeks through 23 months were included as a convenience sample. Overall usage was found to be 46% ranging from 6% to 82%.

Association of acute kidney injury with readmissions after hospitalization for acute exacerbation of chronic obstructive pulmonary disease: a population-based study.
This study examined the association between acute kidney injury (AKI) and readmission with hospitalization for acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Retrospective, population-based cohort data was used from the HCUP State Inpatient Databases from seven states (Arkansas, California, Florida, Iowa, Nebraska, New York, and Utah) from 2010 through 2013. A total of 356,990 patients were identified as hospitalized for AECOPD. Median age was 71 years and 41.9% were male. Of those 7% had a concurrent diagnosis of AKI. Patients with AKI were found to have a significantly higher risk of 30-day all-cause readmission compared to those without AKI as well as a significantly higher risk of 90-day all-cause readmission, particularly for non-respiratory reasons. These reasons included sepsis, acute renal failure, and congestive heart failure.

Social disadvantage, access to care, and disparities in physical functioning among children hospitalized with respiratory illness.
This study examined associations between social disadvantage, access to care, and disparities in physical functioning among children hospitalized with acute respiratory illness. The study cohort included children ages 8-16 years and/or caregivers of children 2 weeks to 16 years admitted to five tertiary care children’s hospitals for three common respiratory illnesses from July 2014 through June 2016. Surveys were completed within 2 to 8 weeks after discharge. The survey assessed social disadvantage, difficulty/delays accessing care, and baseline and follow-up health-related quality of life (HRQoL), and physical functioning using the Pediatric Quality of Life Inventory (PedsQL). A total of 1,325 patients and/or their caregivers completed both PedsQL surveys. Adjusted mean baseline PedsQL scores were significantly lower for patients with social disadvantage (minority race/ethnicity, limited English proficiency, low education, and low income), than for patients with none. There were also disadvantage markers or difficulty/delays accessing care which were associated with lower physical functioning. However, these differences were reduced after hospital discharge.

Researchers investigated the association of obstructive sleep apnea (OSA) with acute asthma severity in a retrospective cohort study that used State Inpatient Databases from eight geographically diverse states. Outcomes examined were markers of acute severity such as mechanical ventilation use, hospital length of stay, and in-hospital mortality. The researchers found that, among patients hospitalized for acute asthma, OSA was associated with a higher risk of noninvasive positive pressure ventilation use and longer length of stay compared with those without OSA.

Hospitalizations associated with respiratory syncytial virus and influenza in children, including children diagnosed with asthma.
This study examined hospitalization rates in children associated with respiratory syncytial virus (RSV) and influenza, including children with asthma. HCUP hospitalization data and additional data to estimate RSV and influenza-associated hospitalization with a respiratory cause was analyzed in different subpopulations of US children between 2003 and 2010. Annual rates of RSV-associated hospitalization was highest in infants and young children, and declined rapidly with age. Influenza hospitalizations also were highest in young children and declined by age 12-17 years. Higher rates of RSV-related and influenza hospitalization in the youngest children with a prior diagnosis of asthma was also found.

Association between outdoor air pollution levels and inpatient outcomes in pediatric pneumonia hospitalizations, 2007 to 2008.
Pneumonia is a leading cause of pediatric admissions. Although air pollutants are associated with poor outcomes, few national studies have examined associations between pollutant levels and inpatient pediatric pneumonia outcomes. In this study, the investigators examined the relationship between ozone (O3) and fine particulate matter with a diameter </=2.5 microm (PM2.5) and outcomes related to disease severity. They concluded that greater levels of O3 and PM2.5 were associated with more severe presentations of pneumonia.

Impact of pneumococcal conjugate vaccines on hospitalizations for pneumonia in the United States.
In this study, the investigators described the existing evidence for both the direct and indirect impact of Pneumococcal conjugate vaccines (PCVs) on pneumonia among children and adults in the US since PCV introduction. The introduction of PCVs into the US routine infant vaccination schedule led to important reductions in the burden of invasive pneumococcal diseases and non-invasive pneumonia among vaccinated and unvaccinated populations. The impact of direct vaccination of older adults in the US since 2014, though difficult to quantify, is currently being evaluated.

Impact of PAP therapy on hospitalization rates in Medicare beneficiaries with COPD and coexisting OSA.
This retrospective cohort study analyzed data from a national sample of fee-for-service Medicare beneficiaries with a diagnosis of chronic obstructive pulmonary disease (COPD) and coexisting obstructive sleep apnea (OSA) who had begun positive airway pressure (PAP) therapy in 2011. The effect of PAP therapy on emergency room visits and hospitalizations for all-cause and COPD-related conditions was also examined. PAP therapy was more beneficial for older adults, those with higher COPD complexity, and those with three or more comorbidities. PAP therapy in elderly patients with overlap syndrome is associated with a reduction in hospitalization for COPD-related conditions, but not for all-cause hospitalizations or ER visits.

Epidemiology and outcomes of granulomatosis with polyangiitis in pediatric and working-age adult populations In the United States: analysis of a large national claims database.
This retrospective cohort study examined the epidemiology and outcomes of granulomatosis with polyangiitis (GPA) in pediatric and working-age adult populations in the US. The study used data from the 2006-2014 Truven Health Analytics MarketScan Commercial Claims and Encounters Database. The incidence is rare in children, with a total of 214 (3.8%) out of 5,562 cases identified as pediatric onset. The incidence rate in children was 1.8 cases per 1 million person-years as opposed to 12.8 cases per 1 million person-years in working age adults. Children were more like to have frequent hospitalizations and severe infections including leukopenia, neutropenia, and hypogammaglobulinemia than the non-elderly adults.

Association between obesity and acute severity among patients hospitalized for asthma exacerbation.
This study examined the association between obesity and exacerbation of asthma symptoms in hospitalized adults (age 18-54 years). This retrospective cohort study used data from 8 diverse US states from 2010-2013. Among 72,086 patients hospitalized for asthma exacerbation, 24% were considered obese. Obesity was associated with a higher use of mechanical ventilation as well as a longer hospital stay. These findings were consistent among all ages, sex, and race/ethnicity.

Long-term acute care hospital use of non-mechanically ventilated hospitalized older adults.
In this observational cohort study, the investigators sought to determine why non-mechanically ventilated hospitalized older adults are transferred to long-term acute care (LTAC) hospitals rather than remaining in the hospital. The authors found that nearly half of the variation in LTAC use is independent of illness severity and is explained by which hospital and what region the individual was hospitalized in.

Acute exacerbation of chronic obstructive pulmonary disease and subsequent risk of emergency department visits and hospitalizations for atrial fibrillation.
Although emerging evidence has suggested the relationship of chronic obstructive pulmonary disease with atrial fibrillation (AF), little is known about whether acute exacerbation of chronic obstructive pulmonary disease (AECOPD) increases the risk of repeated AF-related healthcare utilization. The investigators found that among patients with existing AF, AECOPD was associated with a higher risk of AF-related ED visit or hospitalization in the first 90-day post-AECOPD period.

Association of obstructive sleep apnoea with acute severity of chronic obstructive pulmonary disease exacerbation: a population-based study.
This retrospective cohort study investigated the association of coexistent obstructive sleep apnoea with acute severity markers (i.e. invasive positive pressure ventilation use and hospital length of stay) among adults hospitalised for acute exacerbation of chronic obstructive pulmonary disease.
