Reducing antimicrobial overuse through targeted therapy for patients with community-acquired pneumonia: a study protocol for a cluster-randomized factorial controlled trial (CARE-CAP).
The authors described a planned cluster-randomized controlled trial in 12 hospitals in the Cleveland Clinic Health System to test two approaches to reducing the use of extended-spectrum antibiotics (ESA) in adult patients with community-acquired pneumonia (CAP): rapid diagnostic assays that provide accurate results within hours, and de-escalation after negative bacterial cultures in clinically stable patients. The purpose will be to establish whether the identification of an etiological agent early and pharmacist-led de-escalation can safely reduce the use of ESA in patients with CAP. The findings may also inform clinical guidelines on the management of CAP.

Intravenous to oral antibiotic switch therapy among patients hospitalized with community-acquired pneumonia.
The purpose of this retrospective cohort study was to examine clinical practice guidelines which recommend switching from intravenous (IV) to oral antibiotics once patients are clinically stable. The researchers conducted a study of adults admitted with CAP from 2010 through 2015 and initially treated with IV antibiotics at 642 US hospitals. Switching was defined as discontinuation of IV and initiation of oral antibiotics without interrupting therapy. Patients switched by hospital day 3 were considered early switchers. The study found that of 78,041 CAP patients, 6% were switched early, most frequently to fluoroquinolones. Patients switched early had fewer days on IV antibiotics, shorter duration of inpatient antibiotic treatment, shorter LOS, and lower hospitalization costs, but no significant excesses in 14-day in-hospital mortality or late ICU admission. Patients at a greater mortality risk were less likely to be switched. However, even in hospitals with relatively high switch rates, less than 15% of very low-risk patients were switched early.

Association of chest radiography with outcomes in pediatric pneumonia: a population-based study.
This study’s objective was to evaluate the association of performing a chest radiograph (CXR) with 7-day hospitalization after emergency department (ED) discharge among pediatric patients with community-acquired pneumonia (CAP). This retrospective cohort study included 206,694 children aged 3 months to 17 years discharged from any ED within 8 states from 2014 to 2019. Secondary outcomes included 7-day ED revisits and a 7-day hospitalization with severe CAP. Among these children diagnosed with CAP, rates of 7-day ED revisit, hospitalization, and severe CAP were 8.9%, 1.6%, and 0.4%, respectively. After adjusting for illness severity, CXR was associated with fewer 7-day hospitalizations (1.6% vs 1.7%). CXR performance varied somewhat between EDs (median 91.5%). EDs in the highest quartile had fewer 7-day hospitalizations (1.4% vs 1.9%), ED revisits (8.5% vs 9.4%), and hospitalizations for severe CAP (0.3% vs 0.5%) as compared to EDs with the lowest quartile of CXR utilization.

Derivation and validation of a risk assessment model for drug-resistant pathogens in hospitalized patients with community-acquired pneumonia.
The purpose of this study was to develop and validate a model for risk of resistance to first-line community-acquired pneumonia (CAP) therapy. The study was conducted using data for adults hospitalized for CAP from 177 Premier Healthcare database hospitals and 11 Cleveland Clinic hospitals. The study found that among 138,762 eligible patients in the Premier database, 8.8% had positive cultures and 3.8% had organisms resistant to CAP therapy. The strongest predictor of resistance was infection with a resistant organism in the previous year. Markers of acute illness such as receipt of mechanical ventilation or vasopressors, and chronic illness such as pressure ulcer or paralysis were also related with resistant infections. The study model outperformed the Drug Resistance in Pneumonia (DRIP) model in the Premier holdout sample, the Cleveland Clinic hospitals sample. Clinicians at Premier facilities utilized broad-spectrum antibiotics for 20%-30% of their patients. In discriminating between patients with and without resistant infections, physician judgment slightly outperformed the DRIP instrument but not the study model.

Association of fluoroquinolones or cephalosporin plus macrolide with Clostridioides difficile infection (CDI) after treatment for community-acquired pneumonia.
The purpose of this study was to explore the relationships between the antibiotic regimens of empiric therapy with a respiratory fluoroquinolone or cephalosporin plus macrolide combination and the development of hospital-onset Clostridioides difficile infection (CDI). The researchers used data from 638 United States hospitals and included adults admitted with pneumonia and discharged from July 2010 through June 2015 with a pneumonia diagnosis code who received 3 or more days of either antibiotic regimen. The study sample included 58,060 patients treated with either cephalosporin plus macrolide (36,796 patients) or a fluoroquinolone alone (21,264 patients). 0.35% of patients who received cephalosporin plus macrolide and 0.31% who received a fluoroquinolone developed CDI, making CDI risks similar for fluoroquinolones versus cephalosporin plus macrolide.

Epidemiologic trends in Clostridioides difficile infections in a regional community hospital network.
Clostridioides difficile infection (CDI) remains a leading cause of health care facility-associated infection. A greater understanding of the regional epidemiologic profile of CDI could inform targeted prevention strategies. The objectives of this study was to assess trends in incidence of health care facility-associated and community-acquired CDI among hospitalized patients over time and to conduct a subanalysis of trends in the NAP1 strain of CDI over time.

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.

Healthcare-associated urinary tract infections with onset post hospital discharge.
The objective of this study was to measure the incidence of potentially healthcare-associated (HA), community-onset (CO) urinary tract infection (UTI) in a retrospective cohort of hospitalized patients. Among 3,273 patients at risk for potentially HA-CO UTI, results found that the incidence of HA-CO UTI in the 30 days post discharge was 29.8 per 1,000 patients; independent risk factors included paraplegia, quadriplegia, indwelling catheter during index hospitalization, prior piperacillin-tazobactam prescription, prior penicillin class prescription, and private insurance. The authors conclude that HA-CO UTI may be common within 30 days following hospital discharge, and that their data suggests that surveillance efforts may need to be expanded to capture the full burden to patients and to better inform antibiotic prescribing decisions for patients with a history of hospitalization.

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.

Plasma 25-hydroxyvitamin d and the longitudinal risk of sepsis in the REGARDS cohort..
In this paper, researchers studied low baseline plasma 25-hydroxyvitamin D (25(OH)D) and its association with long-term risk of sepsis. Data from the Reasons for Geographic and Racial Differences in Stroke study was used. Findings reveals that, among community-dwelling US adults, low plasma 25(OH)D measured at a time of relative health was independently associated with increased risk of sepsis.

Comparison of livestock-associated and community-associated Staphylococcus aureus pathogenicity in a mouse model of skin and soft tissue infection.
The goal of this study was to determine the degree to which livestock-associated (LA) Staphylococcus aureus strains contracted by industrial hog-operation (IHO) workers cause disease relative to a representative CA-MRSA strain in a mouse model of skin and soft tissue infection (SSTI). Mice infected with LA-S. aureus strains developed larger lesions with a higher bacterial burden than the CA-MRSA infected mice; the largest lesion size and bacterial burden were observed with a CC398 LA-S. aureus strain which had produced a recurrent SSTI in an IHO worker. The researchers conclude that more attention should be placed on the prevention of spreading LA-S. aureus into human populations.

A clinical prediction tool for extended-spectrum cephalosporin resistance in community-onset Enterobacterales urinary tract infection.
Researchers sought to create a clinical prediction tool for community-onset urinary tract infections (UTIs) due to extended-spectrum cephalosporin-resistant (ESC-R) Enterobacterales (EB). Study participants included patients who presented to an emergency department or outpatient practice with an EB UTI; case patients had ESC-R EB UTIs and control patients had ESC-susceptible EB UTIs. The predictive model was develop by performing a multivariable conditional logistic regression. The researchers found after multivariable analysis that presentation with an ESC-R EB community-onset UTI could be predicted by the following factors: history of malignancy, history of diabetes, recent skilled nursing facility or hospital stay, recent trimethoprim-sulfamethoxazole exposure, pyelonephritis at the time of presentation. They conclude that community-onset ESC-R EB UTI can be predicted by using the proposed scoring system, which can be helpful to guide diagnostic and therapeutic interventions.

Interplay of personal, pet, and environmental colonization in households affected by community-associated methicillin-resistant Staphylococcus aureus.
In this study, the investigators sought to determine the prevalence, molecular epidemiology, and factors associated with Staphylococcus aureus environmental surface and pet colonization in households of children with community-associated methicillin-resistant S. aureus (CA-MRSA) infection. The investigators found that household environments and pet dogs and cats serve as reservoirs of MRSA. Household member MRSA colonization burden predicts environmental MRSA contamination. The authors indicated that longitudinal studies will inform the directionality of household transmission.

Geographic surveillance of community associated MRSA infections in children using electronic health record data.
This study conducted a geographic surveillance of community-associated methicillin resistant Staphylococcus aureas (CA-MRSA) incidence in children from 2000 to 2010 in the Atlanta Metropolitan area. Census tract data was filtered to create maps of antibiotic resistant and non-resistant forms of CA-MRSA infection. Black children and children under the age of 4 were found to have increased risk for CA-MRSA. Poverty also made a difference in the rate of CA-MRSA with neighborhoods with larger households having a higher rate.
