Accuracy of infection reporting in US nursing home ratings.
The objective of this study was to assess the accuracy of publicly reported nursing home data on urinary tract infections (UTIs) and of pneumonia data, which are not publicly reported. Researchers developed a claims-based nursing home-level measure of hospitalized infections and estimated correlations between this and publicly reported ratings. Subjects were Medicare fee-for-service beneficiaries who were nursing home residents and hospitalized for UTI or pneumonia during the study period. Findings suggested that both UTI and pneumonia were substantially underreported in data used for national public reporting. The researchers concluded that alternative approaches were needed to improve surveillance of nursing home quality.

Treatment and outcomes among patients ≥85 years hospitalized with community-acquired pneumonia.
This retrospective cohort study’s objective was to describe community-acquired pneumonia (CAP) among patients ≥85 years and compare them to patients aged 65-74. Findings showed that patients aged 85 and over have different comorbidities and etiologies of CAP, receive less intense treatment, and have greater mortality than patients between 65 and 75 years.

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.

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.

Variation in and hospital characteristics associated with the value of care for Medicare beneficiaries with acute myocardial infarction, heart failure, and pneumonia.
The objectives of this study were to investigate the association between hospital-level 30-day risk-standardized mortality rates (RSMRs) and 30-day risk-standardized payments (RSPs) for acute myocardial infarction (AMI), heart failure (HF), and pneumonia (PNA); to characterize patterns of value in care; and to identify hospital characteristics associated with high-value care (defined by having lower than median RSMRs and RSPs).

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.

Treatment trends and outcomes in healthcare-associated pneumonia.
This retrospective cohort study assessed changes in hospital rates of concordant antibiotic use over time and their correlation with outcomes related to management of healthcare-associated pneumonia (HCAP). The study concluded that only 1 in 5 patients with risk factors for HCAP received treatment that was fully in accordance with guidelines, and many received community-acquired pneumonia (CAP) therapy instead.

Application of a risk score to identify older adults with community-onset pneumonia most likely to benefit from empiric pseudomonas therapy.
The researchers assessed the impact of empiric Pseudomonas pharmacotherapy on 30-day mortality in hospitalized patients with community-onset pneumonia stratified according to their risk (low, medium, or high) of drug-resistant pathogens. By using a risk score, they found that empiric Pseudomonas therapy was associated with lower 30-day mortality in the high-risk group but not the low- or medium-risk groups.

Pneumococcal vaccination guidance for post-acute and long-term care settings: recommendations from AMDA's infection advisory committee.
Sorting out the indications and timing for 13 pneumococcal serotypes and 23 pneumococcal serotypes administration is complex. The authors discuss the importance of pneumococcal vaccination for older adults, detail AMDA-The Society for Post-Acute and Long-Term Care Medicine (The Society)'s recommendations for pneumococcal vaccination practice and procedures, and offer guidance to postacute and long-term care providers supporting the development and effective implementation of pneumococcal vaccine policies.

Pneumonia identification using nursing home records.
The researchers compared three established strategies for defining pneumonia using records from 1,119 residents across 16 nursing homes. They found that recorded diagnosis of pneumonia is a highly sensitive and pragmatic method to ascertain pneumonia in nursing homes, and is recommended for use in quality improvement and research.

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.
