Changes in coding of pneumonia and impact on the hospital readmission reduction program.
Researchers evaluated whether changes in diagnosis assignment explain reductions in 30-day readmission for patients with pneumonia following the Hospital Readmission Reduction Program (HRRP). They conducted a retrospective cohort study of Medicare discharges in HRRP-eligible hospitals; outcomes were 30-day readmission rates for pneumonia under both "narrow" and "broad" definitions that included certain diagnoses of sepsis and aspiration pneumonia. They concluded that changes in the coding of inpatient pneumonia admissions do not explain readmission reduction following the HRRP.

Trends in the use of skilled nursing facility and home health care under the Hospital Readmissions Reduction Program: an interrupted time-series analysis.
Medicare's Hospital Readmission Reduction Program penalizes hospitals with elevated 30-day readmission rates for acute myocardial infarction, heart failure, or pneumonia. The authors investigated if, in order to reduce readmissions, hospitals may have increased referrals to skilled nursing facilities and home health care. They found that hospitals might be shifting to more intensive postacute care to avoid readmissions among seniors with pneumonia. At the same time, penalized hospitals' efforts to prevent readmissions may be keeping higher proportions of their patients in the community.

Antipseudomonal monotherapy or combination therapy for older adults with community-onset pneumonia and multidrug-resistant risk factors: a retrospective cohort study.
Infectious Diseases Society of America guidelines recommend empiric antipseudomonal combination therapy when Pseudomonas is suspected. However, combination antipseudomonal therapy is controversial. This population-based retrospective cohort study compared all-cause 30-day mortality in older patients who received antipseudomonal monotherapy (PMT) or antipseudomonal combination therapy (PCT) for the treatment of community-onset pneumonia. The investigators found that older adults who received combination antipseudomonal therapy for community-onset pneumonia fared worse than those who received monotherapy.

The potential economic value of sputum culture use in patients with community-acquired pneumonia and healthcare-associated pneumonia.
Researchers developed a decision model to determine the economic and clinical value of using sputum cultures in the treatment of community-acquired pneumonia (CAP) and healthcare-associated pneumonia (HCAP) from the hospital perspective under various conditions. They found that, overall, obtaining sputum cultures does not provide significant clinical or economic benefits for CAP or HCAP patients; however, it can reduce costs and shorten overall length of stay under some circumstances. They recommended that clinicians consider their local conditions when making decisions about sputum culture use.

Variation in emergency department adherence to treatment guidelines for inpatient pneumonia and sepsis: a retrospective cohort study.
Evidence-based clinical practice guidelines (CPGs) for the treatment of pneumonia and sepsis have existed for many years with multiple studies suggesting improved patient outcomes. Despite their importance, little is known about variation in emergency department (ED) adherence to these CPGs. The objectives of this study were to estimate variation in ED adherence across CPGs for pneumonia and sepsis and identify patient, provider, and environmental factors associated with adherence.

Association between alcohol use disorders and outcomes of patients hospitalized with community-acquired pneumonia.
The purpose of this study was to compare the causes, treatment, and outcomes of pneumonia in patients with and without alcohol use disorder (AUD). Results suggest that, compared with hospitalized patients with community-acquired pneumonia but without AUD, those with AUD less often harbor resistant organisms. The authors conclude that higher age-adjusted risk of death among patients with AUD appears to be largely attributable to differences in comorbidities, whereas greater use of health care resources may be attributable to alcohol withdrawal.

Changes in use of postacute care associated with accountable care organizations in hip fracture, stroke, and pneumonia hospitalized cohorts.
In this study, researchers examined changes in more and less discretionary condition-specific postacute care use associated with Medicare accountable care organization (ACO) implementation. They found that ACOs decreased spending on postacute care by decreasing use of discretionary services. In addition, ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. The authors also observed decreases in spending, readmission days, and mortality among pneumonia patients.

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.

Effect of audit and feedback on physician adherence to clinical practice guidelines for pneumonia and sepsis.
This study examined the effect of feedback with blinded peer comparison on emergency physician adherence to guidelines for appropriate antibiotic administration for inpatient pneumonia and completion of the 3-hour Surviving Sepsis Bundle for patients with severe sepsis. A quasi-experiment was conducted with attending physicians randomized into 6 clusters at a single urban safety net hospital. Feedback with blinded peer comparison significantly improved guideline adherence from 52% to 65% with feedback.

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.

Facilitators of interdepartmental quality improvement: a mixed-methods analysis of a collaborative to improve pediatric community-acquired pneumonia management.
This study examined the relationship between emergency room (ER) physicians and hospital pediatricians in the use of narrow-spectrum antibiotics to treat children hospitalized with pneumonia. There were eight inter-related domains that were identified that contribute to successful quality improvement efforts. These domains include hospital leadership and support; quality improvement champions, and interdepartmental relationships.

The role of influenza in the epidemiology of pneumonia.
The researchers used longitudinal influenza and pneumonia incidence data, at different spatial resolutions and across different epidemiological periods, to infer the nature, timing and the intensity of influenza-pneumonia interaction. They concluded that influenza infection substantially enhances the risk of pneumonia, though only for a short period.

Association of respiratory viruses with outcomes of severe childhood pneumonia in Botswana.
The authors examined whether detection of respiratory viruses predicts acute lower respiratory tract infection (ALRI) outcomes in low- and middle-income countries. They found that respiratory viruses were detected from most children hospitalized with ALRI in Botswana, but only respiratory syncytial virus (RSV) and human metapneumovirus were more frequent than among children without ALRI. Further, detection of RSV from children with ALRI predicted a protracted illness course but lower mortality compared with non-RSV viruses.

Gaming hospital-level pneumonia 30-day mortality and readmission measures by legitimate changes to diagnostic coding.
The researchers sought to determine the degree to which hospitals can game mortality or readmission measures and change their rankings by recoding patients with pneumonia. They concluded that hospitals can improve apparent pneumonia mortality and readmission rates by recoding pneumonia patients. Centers for Medicare and Medicaid Services should consider changes to their methods used to calculate hospital-level pneumonia outcome measures.

Sore throat: avoid overcomplicating the uncomplicated.
In this editorial, the author described issues involving sore throat diagnosis and delineated various points concerning an article within the same journal issue, concluding that physicians should remember that the prevalence of group A streptococcus in adults with a sore throat is approximately 10%; and that they should use the Centor scoring criteria; selectively use rapid antigen-detection testing; limit antibiotic treatment to patients most likely to have group A streptococcus; and most of the time when prescribing antibiotics, use penicillin.
