Retrospective assessment of antimicrobial stewardship initiative in outpatient use of ertapenem for uncomplicated extended spectrum beta lactamase Enterobacteriaceae urinary tract infections

A step further: Antibiotic stewardship programme in home hospital

OBJECTIVE

To evaluate the adequacy of empirical antibiotic prescription and the duration of antibiotic therapy for infected patients admitted for conventional hospitalization (CH) and Hospitalization at Home (HaH) after implementation of an antibiotic stewardship programs (ASP) in HaH.

DESIGN

Retrospective cohort study.

PATIENTS

Patients admitted for infection to Emergency Department between October and December 2023. "CH-ASP cohort" was admitted to CH with ASP intervention, "CH cohort" was admitted to CH without ASP intervention, "HaH cohort" was admitted to HaH (integrated daily ASP intervention).

RESULTS

Ninety-one patients were analyzed in CH-ASP, 60 in CH, and 101 in HaH. The ASP made recommendations on empirical antibiotic therapy for 175 patients (92 %) with a 98 % acceptance rate. For 111 patients (44 %) the ASP made recommendations on antibiotic duration (24 % CH-ASP vs 89 % HaH, p < 0.001), with a 73 % acceptance rate (41 % CH-ASP vs 81 % HaH, p < 0.001). Empirical antibiotic adequacy was 94 % (93 % CH-ASP vs 87 % CH vs 100 % HaH, p = 0.006). Median duration of antibiotic therapy was nine days in CH-ASP and CH vs seven in HaH (p < 0.001). There were no differences in mortality and readmissions. In the multivariate analysis, patients in CH-ASP and CH had total duration of antibiotic therapy of 2.2 (95 % CI: 0.2-4.2) and 3 days more (95 % CI: 0.8-5.3) respectively as compared to HaH.

CONCLUSIONS

ASP improves empirical antibiotic adequacy in patients admitted for infection. ASP in HaH, because of high acceptance of intervention regarding antibiotic duration, achieves shorter treatment durations without increased mortality or readmission.

A Baker's Dozen of Top Antimicrobial Stewardship Intervention Publications in Non-Hospital Care Settings in 2021

The scope of antimicrobial stewardship programs has expanded beyond the acute hospital setting. The need to optimize antimicrobial use in emergency departments, urgent, primary, and specialty care clinics, nursing homes, and long-term care facilities prompted the development of core elements of stewardship programs in these settings. Identifying the most innovative and well-designed stewardship literature in these novel stewardship areas can be challenging. The Southeastern Research Group Endeavor (SERGE-45) network evaluated antimicrobial stewardship-related, peer-reviewed literature published in 2021 that detailed actionable interventions specific to the nonhospital setting. The top 13 publications were summarized following identification using a modified Delphi technique. This article highlights the selected interventions and may serve as a key resource for expansion of antimicrobial stewardship programs beyond the acute hospital setting.

Conceptual framework of antibiotic stewardship programs in reducing ESBL-producing Enterobacteriaceae: a systematic review and meta-analysis

Today, the phenomenon of antibiotic resistance has become one of the main concerns of health system around the world. Antimicrobial stewardship programs (ASPs) are considered as the most important strategy in optimizing antibiotic consumption, which in turn reduce the emergence of multidrug/extensively drug-resistant (MDR/XDR) microorganisms, as well as reducing mortality and healthcare costs. However, the effectiveness of APSs in controlling the spread of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae has not been investigated. The pooled odds ratio for the effectiveness of ASPs in reducing ESBL-producing Enterobacteriaceae was 0.82 (95% CI: 0.70-0.98; P value: 0.03); our results showed that in group with implemented ASPs, the prevalence of infection associated with these bacteria had been reduced by 11.8%. Overall, antimicrobial stewardship strategies are significantly effective in reducing ESBL-producing Enterobacteriaceae infections. The present study concluded that a comprehensive stewardship program will certainly reduce the mortality rate, as well as hospitalization stay and treatment costs. In general, our findings strongly support the performance of ASPs in healthcare centers.
