A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2022.

Keeping abreast of the antimicrobial stewardship-related articles published each year is challenging. The Southeastern Research Group Endeavor identified antimicrobial stewardship-related, peer-reviewed literature that detailed an actionable intervention during 2022. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight actionable interventions used by antimicrobial stewardship programs to capture potentially effective strategies for local implementation.

Change in Antimicrobial Use During COVID-19 Pandemic in South Carolina Hospitals: A Multicenter Observational Cohort Study.

OBJECTIVES: This retrospective cohort study examined the impact of the pandemic on antimicrobial use (AU) in South Carolina hospitals. METHODS: Antimicrobial use in days of therapy (DOT) per 1000 days-present was evaluated in 17 hospitals in South Carolina. Matched-pairs mean difference was used to compare AU during the pandemic (March-June 2020) with that during the same months in 2019 in hospitals that did and did not admit patients with COVID-19. RESULTS: There was a 6.6% increase in overall AU in the seven hospitals that admitted patients with COVID-19 (from 530.9 to 565.8; mean difference (MD) 34.9 DOT/1000 days-present; 95% CI 4.3, 65.6; P = 0.03). There was no significant change in overall AU in the remaining 10 hospitals that did not admit patients with COVID-19 (MD 6.0 DOT/1000 days-present; 95% CI -55.5, 67.6; P = 0.83). Most of the increase in AU in the seven hospitals that admitted patients with COVID-19 was observed in broad-spectrum antimicrobial agents. A 16.4% increase was observed in agents predominantly used for hospital-onset infections (from 122.3 to 142.5; MD 20.1 DOT/1000 days-present; 95% CI 11.1, 29.1; P = 0.002). There was also a 9.9% increase in the use of anti-methicillin-resistant Staphylococcus aureus (MRSA) agents (from 66.7 to 73.3; MD 6.6 DOT/1000 days-present; 95% CI 2.3, 10.8; P = 0.01). CONCLUSION: The COVID-19 pandemic appears to drive overall and broad-spectrum antimicrobial use in South Carolina hospitals admitting patients with COVID-19. Additional antimicrobial stewardship resources are needed to curtail excessive antimicrobial use in hospitals to prevent subsequent increases in antimicrobial resistance and Clostridioides difficile infection rates, given the continuing nature of the pandemic.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2019.

Staying current on literature related to antimicrobial stewardship can be challenging given the ever-increasing number of published articles. The Southeastern Research Group Endeavor (SERGE-45) identified antimicrobial stewardship-related peer-reviewed literature that detailed an actionable intervention for 2019. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight the actionable intervention used by antimicrobial stewardship programs to provide key stewardship literature for teaching and training and to identify potential intervention opportunities within one's institution.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in 2017.

With an increasing number of antimicrobial stewardship-related articles published each year, attempting to stay current is challenging. The Southeastern Research Group Endeavor (SERGE-45) identified antimicrobial stewardship-related peer-reviewed literature that detailed an "actionable" intervention for 2017. The top 13 publications were selected using a modified Delphi technique. These manuscripts were reviewed to highlight the "actionable" intervention used by antimicrobial stewardship programs to provide key stewardship literature for training and teaching and identify potential intervention opportunities within their institutions.

Safety and effectiveness of daptomycin across a hospitalized obese population: results of a multicenter investigation in the southeastern United States.

STUDY OBJECTIVE: Data are limited for antimicrobial outcomes in obese patients. This study investigated the safety and clinical outcomes of daptomycin therapy in a hospitalized obese population in the southeastern United States. DESIGN: Multicenter retrospective cohort study. SETTING: Thirteen hospitals in the southeastern United States. PATIENTS: A total of 126 hospitalized adult obese patients (body mass index [BMI] more than 30 kg/m(2) ) admitted from January 2005 through May 2010 who received daptomycin dosed on actual body weight for any indication for a minimum of 7 days. MEASUREMENTS AND MAIN RESULTS: Primary safety outcomes included incidence of creatine phosphokinase (CPK) elevations more than 1000 units/L, more than 500 units/L, myalgias, and discontinuation of therapy due to adverse drug events (ADEs). Patients were stratified by BMI class (I, II, or III) for analyses. The average weight was 121 kg, and 39% of patients were considered morbidly obese. Factors associated with an increased risk of primary safety outcomes were assessed through regression analysis. Clinical effectiveness was evaluated as a secondary outcome. CPK elevations more than 1000 units/L occurred in 8.4% of evaluable patients and specifically in 1 (3.6%), 3 (10.3%), and 4 (10.5%) patients in BMI class I, II, and III, respectively (p=0.554). CPK elevations more than 500 units/L occurred in 13.7% of patients with no statistically significant difference noted across BMI classes. Discontinuation due to ADEs occurred in 8 patients (6.3%). One patient developed rhabdomyolysis on day 9 of therapy. Clinical effectiveness was documented in 71% of patients and was consistent across BMI classes. CONCLUSION: Although elevations in CPK increased in high-risk obese patients on daptomycin, discontinuation rates due to ADEs remained low. Further evaluation in a prospective trial is warranted.
