Antimicrobial resistance is a growing concern in sub-Saharan Africa, and antimicrobial stewardship (AMS) programs have not been widely implemented in this region. We evaluated antibiotic prescribing patterns and concordance with national guidelines at Mbeya Zonal Referral Hospital (MZRH) in Tanzania. Adult inpatient medical records were chronologically reviewed from January 1, 2018 until 100 records documenting antibiotic therapy were evaluated. The primary endpoint was concordance with national guidelines for indication-based antibiotic selection and duration. Data were summarized using descriptive statistics. Overall, 155 records with sufficient data were reviewed. The 100 records which involved antibiotic therapy represented 171 unique antibiotic courses. The most common indication for antibiotics was bacterial pneumonia. Ceftriaxone and metronidazole, the most commonly used antibiotics, were administered in 40% and 24% of courses, respectively. Indication-based antibiotic selection was concordant with national guidelines in 63% of courses, but this fell to 15% when course duration was taken into account. Antibiotic courses were completed as prescribed 28% of the time among evaluable courses. A microbiologic culture of any kind was obtained in 17% of patients. In conclusion, antibiotic therapy was often incomplete, was generally guideline discordant, exhibited limited diversity of selection, and frequently lacked diagnostic confirmation. These data, combined with local susceptibility patterns, may be used to foster AMS efforts for improved compliance with guidelines at MZRH in the future.
