Cost of pediatric pneumonia episodes with or without chest radiography.
Researchers sought to assess the costs of community-acquired pneumonia (CAP) episodes with and without chest radiograph (CXR) among children discharged from the pediatric emergency department. Their retrospective cohort study used data from the Healthcare Cost and Utilization Project State ED and Inpatient Databases on children aged 3 months to 18 years with CAP in eight states from 2014 to 2019. The results indicated that use of CXR for CAP diagnosis is associated with lower costs when considering the subsequent provision of care among patients who need additional health care after initial emergency department discharge.

Temporal trends in postoperative and ventilator-associated pneumonia in the United States.
The purpose of this retrospective cohort study was to assess change in rates of postoperative pneumonia and ventilator-associated pneumonia among patients hospitalized in the United States during 2009-2019. The study found that among 58,618 patients undergoing major surgical procedures between 2009 and 2019, the observed rate of postoperative pneumonia from 2009-2011 was 1.9% and decreased to 1.3% during 2017-2019. The adjusted annual risk each year, compared to the prior year, was 0.94. Among 4,007 patients hospitalized for any of the 4 conditions at risk for ventilator-associated pneumonia during 2009-2019, the researchers did not detect a significant change in observed or adjusted rates. Observed rates clustered around 10%, and adjusted annual risk compared to the prior year was 0.99.

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.

Association of obstructive sleep apnea with all-cause readmissions after hospitalization for asthma exacerbation in adults aged 18-54 years: a population-based study, 2010-2013.
The authors sought to investigate associations between obstructive sleep apnea (OSA) and readmission risk after hospitalization for asthma exacerbation using data from State Inpatient Databases from seven U.S. states. They found that, overall, OSA was associated with a significantly higher incident rate of all-cause readmission. Additionally, OSA was associated with higher incident rates of readmissions for five major diseases: asthma, COPD, respiratory failure, pneumonia, and congestive heart failure, compared to non-OSA.

Antenatal corticosteroid administration in late-preterm gestations: a cost-effectiveness analysis.
The purpose of this study was to evaluate whether administration of antenatal late-preterm betamethasone was cost-effective in the immediate neonatal period. Cost-effectiveness analysis of late-preterm betamethasone administration with a time horizon of 7.5 days was conducted using a health-system perspective The investigators concluded that administration of betamethasone in the late-preterm period was likely not cost-effective in the short-term.

The epidemiology of respiratory failure in the United States 2002-2017: a serial cross-sectional study.
Investigators used HCUP data to study the longitudinal national epidemiology of respiratory failure with mechanical ventilation. Examining different case definitions for respiratory failure, they found a large increase in the population incidence and decrease in the hospital mortality for respiratory failure diagnosis codes with more modest changes in procedural codes for invasive mechanical ventilation. Further, there was a large increase in incidence of noninvasive mechanical ventilation.

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.

Trends in regionalization of emergency care for common pediatric conditions.
This study examined trends in regionalization of emergency care for common pediatric conditions. The authors sought to determine how the likelihood of definitive care has changed for 3 common conditions: asthma, croup, and gastroenteritis. They used the National Emergency Department Sample Database to study children from 2008 to 2016 who presented to emergency departments with those primary diagnoses, excluding critically ill patients. Researchers conducted analyses by stratification of annual emergency department pediatric volume categorized by quartiles. Referral rates increased for all conditions in all volume quartiles, with referral rates greatest in the lowest pediatric volume quartile.

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.

ICU utilization for patients with acute exacerbation of chronic obstructive pulmonary disease receiving noninvasive ventilation.
This retrospective cohort study investigated whether patients with chronic obstructive pulmonary disease (COPD) could safely receive noninvasive ventilation outside of ICU. Researchers examined 5,081 hospitalizations from 424 hospitals, using data from the State Inpatient Database. Researchers concluded that COPD patients who receive noninvasive ventilation had similar in-hospital mortality rates across the ICU utilization spectrum, but a lower rate of receiving invasive monitors. The results suggest that noninvasive ventilation can be delivered safely outside of ICU, but the researchers advocate that hospital-specific risk assessment be used if a hospital is considering changing its noninvasive ventilation policy.

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.

Current state of empyema management.
The goal of this study was to examine current treatment practices and outcomes for inpatient treatment of empyema. A comprehensive, longitudinal data set from the New York State Inpatient Database, encompassing an entire state cohort of hospitalized patients, was used. The cohort included 4,095 patients who were undergoing intervention for primary empyema and were discharged 2009 to 2014 with chest tube, video-assisted thoracoscopic surgery (VATS) decortication and drainage, or open drainage and decortication. Patients were categorized into these three groups by definitive treatment during their initial hospitalization. The findings indicate that patients who were managed with chest tubes showed higher readmission and reintervention rates, suggesting that some of these patients may benefit from earlier definitive surgical intervention.

Reduced risk of acute exacerbation of COPD after bariatric surgery: a self-controlled case series study.
Little is known about the impact of weight reduction on chronic obstructive pulmonary disease (COPD)-related outcomes in patients who are obese. This study found that the risk of an ED visit or hospitalization for acute exacerbation of COPD substantially decreased after bariatric surgery in patients who are obese. This observation suggests the effectiveness of substantial weight reduction on COPD morbidity.

Obesity and severity of acute exacerbation of chronic obstructive pulmonary disease.
A study was done to determine if there was an increase in severity and mortality with chronic obstructive pulmonary disease (COPD) patients who were also obese. Researchers used data from 2012-2013 State Inpatient Databases data of seven U.S. states. 17% of COPD patients in the database were defined as obese. Obesity was shown to increase use of ventilation, increased hospital stays but not in-hospital mortality.

On the relative role of different age groups during epidemics associated with respiratory syncytial virus.
This study evaluated the roles played by individuals in different age groups during respiratory syncytial virus (RSV) epidemics in the United States between 2001 and 2012, using the previously defined relative risk (RR) statistic estimated from the hospitalization data from the Healthcare Cost and Utilization Project. Its estimates suggest the prominent relative roles of children aged </=10 years (particularly among those aged 3-6 years) in propagating RSV epidemics.

Hospital variation in early tracheostomy in the United States: a population-based study.
The researchers determined between-hospital variation in early tracheostomy utilization and the association of early tracheostomy with patient outcomes using hierarchical regression. They concluded that early tracheostomy is potentially overused among mechanically ventilated trauma patients, with nearly half of tracheostomies performed within the first week of mechanical ventilation and large unexplained hospital variation, without clear benefits.

Association between respiratory syncytial virus activity and pneumococcal disease in infants: a time series analysis of US hospitalization data.
The researchers evaluated whether variations in respiratory syncytial virus (RSV) epidemic timing and magnitude are associated with variations in pneumococcal disease epidemics and whether changes in pneumococcal disease following the introduction of a pneumococcal conjugate vaccine (PCV7) were associated with changes in the rate of RSV hospitalizations. Their findings indicate that RSV is associated with increases in the incidence of pneumococcal pneumonia.

Environmental drivers of the spatiotemporal dynamics of respiratory syncytial virus in the United States.
The authors examined the association between environmental variables and state-specific measures of respiratory syncytial virus (RSV) seasonality. They found that states with low mean vapor pressure and the largest seasonal variation in potential evapotranspiration tended to experience biennial patterns of RSV activity, with alternating years of "early-big" and "late-small" epidemics. Their results successfully connected environmental drivers to the epidemic dynamics of RSV; however, the results do not fully explain why RSV activity begins in Florida, one of the warmest states, when RSV is a winter-seasonal pathogen.

Lower respiratory tract infection hospitalizations among American Indian/Alaska Native children and the general United States child population.
The authors described the change in lower respiratory tract infection-associated hospitalization rates for American Indian and Alaskan Native (AI/AN) children and for the general US child population aged less than 5 years. They found that the 2009-2011 AI/AN child average annual LRTI-associated hospitalization rate was 1.5 times higher than the US child rate. The Alaska and Southwest regions had the highest rates. The disparity was greatest for infant pneumonia-associated and 2009-2010 H1N1 influenza-associated hospitalizations.
