Comparison of criteria for determining appropriateness of antibiotic prescribing in nursing homes.
Researchers studied the extent to which the revised McGeer and Loeb criteria overlap and can be used interchangeably for tracking antibiotic appropriateness in nursing homes. Using a cross-sectional chart review in 5 Wisconsin nursing homes, they found that levels of agreement between the revised McGeer and Loeb criteria were moderate for urinary tract infections, fair for skin and soft-tissue infections, and slight for respiratory tract infections. They concluded that agreement between the revised McGeer and Loeb criteria is limited, and that nursing homes should employ the revised McGeer and Loeb criteria for their intended purposes.

Implementation of an antibiotic stewardship program in long-term care facilities across the US.
The purpose of this study was to determine if AHRQ’s Safety Program for Improving Antibiotic Use was associated with reductions in antibiotic use in long-term care (LTC) facilities in the US. Findings showed that participation in the AHRQ safety program was associated with the development of antibiotic stewardship programs (ASPs) that actively engaged clinical staff in the decision-making processes around antibiotic prescriptions in participating LTC facilities. The reduction in days of antibiotic therapy and starts, which was more pronounced in more engaged facilities, indicated that implementation of this multifaceted program may support successful ASPs in LTC settings.

Improvements in antibiotic appropriateness for cystitis in older nursing home residents: a quality improvement study with randomized assignment.
This study evaluated the impact of an educational quality improvement initiative on the appropriateness of antibiotic prescribing restricted to uncomplicated cystitis in older noncatheterized nursing home residents. This 1-year case-control study used 25 participating nursing homes that were randomized to the intervention or usual care group by strata that included state, urban/rural status, bed size, and geographic separation. A total of 75 cases of cystitis were found in the intervention groups and 92 in the control groups. The intervention group had a nonsignificant 21% reduction in the risk of antibiotic prescribing. There was a favorable comparison in appropriateness of duration. However, the intervention group had more problems with drug-drug interactions than the control group (8% vs 1%). There were also more problems with dosage in the intervention group. Both groups had similar rates of problems with choice or effectiveness (44% vs 45%). The most common antibiotic class that was prescribed inappropriately was quinolones.

Workflow barriers and strategies to reduce antibiotic overuse in nursing homes.
Antibiotic overuse is a significant problem in nursing homes (NHs). Strategies to improve antibiotic prescribing practices in NHs are a critical need. In this study, the investigators analyzed antibiotic prescribing workflows to identify strategies for improving antibiotic prescribing in NHs. They found that such strategies included structured information tools, nurse and prescriber education, and organizational improvement.

A multifaceted antimicrobial stewardship program for the treatment of uncomplicated cystitis in nursing home residents.
This study describes the result of implementing a multifaceted antimicrobial stewardship program to reduce antibiotic use in nursing homes for urinary tract infections that are unlikely cystitis. Reduction in antibiotic use decreases incidence of Clostridioides difficile (C difficile) infections, as well as adverse drug reactions and antimicrobial drug resistance. This one-year case-control study included 12 intervention nursing homes and 13 control group nursing homes. The intervention nursing homes received a 1-hour introductory webinar, pocket-sized educational cards, tools for system change, and educational clinical vignettes addressing the diagnosis and treatment of suspected uncomplicated cystitis. Additionally, they received a monthly coaching call as well as a quarterly feedback report. In the intervention nursing homes, fewer unlikely cystitis cases were treated with antibiotics and C difficile infection rates were also lower. There was no increase in all-cause hospitalizations or deaths due to the intervention.

Effect of antibiotic time-outs on modification of antibiotic prescriptions in nursing homes.
The purpose of this study was to evaluate the impact of a stewardship intervention, promoting the use of antibiotic time-outs (ATOs) on the frequency and types of antibiotic change events (ACEs) in nursing homes. Data on antibiotic prescriptions in 11 nursing homes were collected over 25 months and categorized as early discontinuation, class modification, or administration modification ACEs. Findings showed that the impact of an ATO intervention in study nursing homes was mixed with increases in early discontinuation ACEs offset by reductions in class modification ACEs. Recommendations include further research on the potential value of ATO interventions in nursing homes.

Antibiotic stewardship for older adults in ambulatory care settings: addressing an unmet challenge.
Inappropriate antibiotic use is common in older adults (aged >65 y), and they are particularly vulnerable to serious antibiotic-associated adverse effects such as cardiac arrhythmias, delirium, aortic dissection, drug-drug interactions, and Clostridioides difficile. In this study, to help improve the clinical care of older adults, the investigators reviewed drivers of antibiotic prescribing in this population, explored systems aspects of ambulatory care that can create barriers to optimal antibiotic use, discussed existing stewardship interventions, and provided guidance on priority areas for future inquiry.

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.

Antimicrobial resistance patterns of urine culture specimens from 27 nursing homes: impact of a two-year antimicrobial stewardship intervention.
This study evaluated the impact of a two-year antimicrobial stewardship intervention program at 27 nursing homes. The objective was to identify changes in the prevalence and antimicrobial resistance patterns of potentially pathogenic bacteria in urine cultures. All urine cultures were audited during the time period, and out of 6,718 total urine cultures collected, 68% were positive for potentially antimicrobial resistant bacteria. Most of the bacteria identified were E. coli, Proteus spp, and Klebsiella pneumonia. During the 2-year program there was a significant decrease in nitrofurantoin resistance among E. coli and ciprofloxacin resistant among Proteus spp, but carbanepem resistance increased for Proteus spp. Overall, while there was some reduction in antibiotic resistance, the reductions were too small and scattered to conclude the intervention made a big impact.

Infections in older adults: a case-based discussion series emphasizing antibiotic stewardship.
This article describes the results of a series of 1-hour case-based discussions on recognition, diagnosis, and infections common in older adults, including those living in long-term care settings, and antibiotic stewardship that were developed by the authors. This series of five discussions was held at 15 Veterans Affairs medical centers in their skilled nursing centers. There were participants from an array of disciplines who completed an evaluation as well as pre- and post-course knowledge assessment. Total participants numbered from 68 to 108 per center. There were positive assessments, with many participants saying they were likely to make changes to help combat health associated infections.

Post-hospitalization treatment regimen and readmission for C. difficile colitis in Medicare beneficiaries.
C. difficile (CDI) has surpassed methicillin-resistant staph aureus as the most common nosocomial infection with recurrence reaching 30% and the elderly being disproportionately affected. The authors hypothesized that post-discharge antibiotic therapy for continued CDI treatment reduces readmissions. The study concluded that patients discharged with single-drug therapy for CDI had lower readmission rates compared to patients discharged on no ongoing CDI treatment suggesting that short-term monotherapy may be beneficial in inducing eradication and preventing relapse.

Nurse and medical provider perspectives on antibiotic stewardship in nursing homes.
The objective of this cross sectional survey was to examine perspectives on antibiotic use and antibiotic stewardship of nurses and medical providers in nursing homes ( NHs). The investigators concluded that nursing staff and medical providers share a commitment to reducing unnecessary antibiotic use. Antibiotic stewardship interventions should foster cooperation and build competency to implement alternative management approaches and to educate residents and families. Nurse leaders and medical providers with long-term care training may be especially effective champions for antibiotic stewardship.
