Abstract
BACKGROUND: Inappropriate prescribing of antibiotics is a global problem. We assessed the prescribing patterns of antibiotics in three public primary healthcare centres (PHCCs) in Maseru, Lesotho. OBJECTIVES: A cross-sectional point prevalence survey was employed using patients' prescription booklets from October 2022 to December 2022. METHOD: Antibiotics were categorised according to the World Health Organization (WHO) AWaRe classification and assessed by Defined Daily Dose (DDD)/100 outpatients/day to measure relative consumption of each antibiotic as a percentage of total consumption, Access-to-Watch index (AW-I) and Amoxicillin Index (A-I). RESULTS: Of the 624 participants (median age 35 [interquartile range {IQR}: 45-26] years), 71.5% (n = 446) were female. Overall mean (standard deviation [s.d.]) antibiotic consumption was 1.48 (0.13) DDD/100 outpatients/day, with PHCC-1 at 1.64, PHCC-2 at 1.33 and PHCC-3 at 1.47 DDD/100 outpatients/day. The median (IQR) AW-I was 4.64 (3.42-9.45) and the A-I was 1.41 (0.87-1.95). The most frequently prescribed Access group antibiotics included amoxicillin (PHCC-2: 45.9%, overall 1.33 DDD/100 outpatients/day; PHCC-3: 24.5%, 1.47 DDD/100 outpatients/day, and PHCC-1: 23.2%, 1.64 DDD/100 outpatients/day) and doxycycline (PHCC-3: 29.9%, 1.47 DDD/100 outpatients/day, 24.1%, PHCC-2: 1.33 DDD/100 outpatients/day). Erythromycin was the most prescribed Watch group antibiotic for all PHCCs. CONCLUSION: High consumption of Access-group antibiotics was observed. The Watch group's antibiotic use, particularly erythromycin, requires the implementation of stewardship programmes. Results may be a baseline for establishing antibiotic stewardship in Lesotho's PHCCs. CONTRIBUTION: Our study addressed the scarcity of data on antibiotic prescribing patterns in PHCCs in Lesotho using the AWaRe classification system recommended for monitoring antibiotic prescribing and promoting rational use.
