Multidrug-resistant (MDR) bacteria are a global health threat, notably in low- and middle-income countries. The aim of this review was to estimate the prevalence multidrug-resistant healthcare community settings West Africa. In accordance with PRISMA guidelines, we searched PubMed, CINAHL, African Index Medicus, other databases for studies published from 2010 onward. Data on MDR bacterial prevalence, study characteristics, infection types were extracted analyzed via R software. Subgroup analyses performed explore differences across sample types.

Introduction: Antimicrobial stewardship (AMS) can improve the rational use of antibiotics in hospitals. This study assessed impact a multifaceted AMS intervention on antibiotic and prescribing patterns at three tertiary hospitals Zambia. Methods: Point Prevalence Surveys (PPS) were conducted August 2022 October 2023. It was part 3-year demonstration project that aimed to optimize treating urinary tract infections (UTIs) bloodstream (BSIs) various health sector settings Up 170 medical records 265 2023 included assessment. Results: Overall, prevalence this PPS 75%. Eighty-one percent (81%) 71% patients least one 2023, respectively, indicating decrease 10%. Similarly, ceftriaxone, most prescribed antibiotic, declined from an average 48% 38% Adherence Standard Treatment Guidelines (STGs) slightly increased 42% 45% Additionally, reduced 1.38 1.21. Conclusions: had early positive adherence Guidelines.
