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.

Respiratory viral testing and antibacterial treatment in patients hospitalized with community-acquired pneumonia.
Researchers studied the frequency of respiratory viral testing and its associations with antimicrobial utilization in adult patients hospitalized with community-acquired pneumonia. They found that, of patients with pneumonia on admission, 24.5% were tested for respiratory viruses, 94.8% were tested for influenza, and 20.7% were tested for other viruses. They concluded that a minority of patients hospitalized with pneumonia were tested for respiratory viruses; only a fraction of potential viral pathogens were assayed; and patients with positive viral tests often received long antibacterial courses.

De-escalation of empiric antibiotics following negative cultures in hospitalized patients with pneumonia: rates and outcomes.
This study assessed antibiotic de-escalation practices across hospitals and their associations with outcomes in hospitalized patients diagnosed with pneumonia with negative cultures. The authors included 14,170 adults admitted with pneumonia in 2010-2015 to 164 US hospitals if they had negative blood and/or respiratory cultures and received both anti-MRSA and antipseudomonal agents other than quinolones. If empiric drugs were stopped on day 4 while continuing another antibiotic it was defined at de-escalation. Patients were propensity adjusted for de-escalation and compared on in-hospital 14-day mortality, late deterioration with ICU transfer, length-of-stay (LOS) and costs. Thirteen percent (1924 patients) had both initial empiric drugs stopped by hospital day 4. De-escalation rates at hospitals ranged from 2-35% and the established rate quartiles were not significantly associated with outcomes. Even at hospitals in the top quartile of de-escalation, the de-escalation rates were lower than 50%.

Risk factors associated with Pneumocystis jirovecii pneumonia in juvenile myositis in North America.
Pneumocystis jirovecii pneumonia (PJP) is associated with significant morbidity and mortality in adult myositis patients; however, there are few studies examining PJP in juvenile myositis [juvenile idiopathic inflammatory myopathy (JIIM)]. The purpose of this study was to determine the risk factors and clinical phenotypes associated with PJP in JIIM. The investigators concluded that having PJP was associated with more immunosuppressive therapy, anti-MDA5 autoantibodies, Asian race and certain clinical features, including digital infarcts, cutaneous ulcerations and interstitial lung disease.

A nationwide assessment of the association of smoking bans and cigarette taxes with hospitalizations for acute myocardial infarction, heart failure, and pneumonia.
No national study using complete hospitalization counts by area that accounts for contemporaneous controls including state cigarette taxes has been conducted. This study in 28 states found that smoking bans lowered pneumonia hospitalization rates for persons ages 60 to 74 years and higher cigarette taxes were associated with lower heart failure hospitalizations for all ages and fewer pneumonia hospitalizations for adults aged 60 to 74.

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.

Colonization with 19F and other pneumococcal conjugate vaccine serotypes in children in St. Louis, Missouri, USA.
The primary goal of this study was to determine the vaccine-type (VT) serotype prevalence of nasopharyngeal (NP) pneumococcal colonization of children residing in the St. Louis, MO, USA metropolitan area following introduction of the 13-valent pneumococcal conjugate vaccine in 2010. It concluded that children in St. Louis exhibit a higher prevalence of VT serotypes among pneumococcal carriage isolates than has been reported in other areas in the US.

Enhancing comparative effectiveness research with automated pediatric pneumonia detection in a multi-institutional clinical repository: a PHIS+ pilot study.
The aim of this study was to develop an automated, scalable, and accurate method to determine the presence or absence of pneumonia in children using chest imaging reports. It found that, when compared with each of the domain experts manually annotating these reports, the new Natural Language Processing (NLP) application developed by the researchers allowed for significantly higher sensitivity (.71 vs .527) and similar positive predictive value and specificity.

Development and evaluation of a patient education video promoting pneumococcal vaccination.
The researchers aimed to develop and refine a patient education video about pneumococcal polysaccharide vaccination (PPSV23) and to assess patient perceptions regarding video content and receipt of video during a clinic visit. They found that focus group participants had positive reactions to the video but suggested reducing the intensity of messages about pneumonia severity. Participants shown the revised video during a clinic visit perceived it to be easy to understand and informative.

Childhood pneumococcal disease in Africa - a systematic review and meta-analysis of incidence, serotype distribution, and antimicrobial susceptibility.
This study provided updated estimates of the incidence, serotype distribution, and antimicrobial susceptibility profile of Streptococcus pneumoniae causing disease in Africa. It concluded that, although the incidence of invasive pneumococcal disease (IPD) in young children in Africa is substantial, currently available conjugate vaccines are estimated to cover the majority of invasive disease-causing pneumococcal serotypes.

Predicting 30-day pneumonia readmissions using electronic health record data.
The objective of this study was to develop pneumonia-specific readmission risk-prediction models using EHR data from the first day and from the entire hospital stay ("full stay"). The investigators concluded that EHR data collected from the entire hospitalization can accurately predict readmission risk among patients hospitalized for pneumonia. They suggest that this approach outperforms a first-day pneumonia-specific model, the Centers for Medicare and Medicaid Services pneumonia model, and 2 commonly used pneumonia severity of illness scores.

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.
