Antibiotic use and resistance: Knowledge, attitudes and perceptions among primary care prescribers in South Africa
AbstractBackground. Antibiotic resistance (ABR) is a major threat to global health, driven in part by inappropriate prescription of antibiotics in primary care. Objectives. To describe South African (SA) prescribers’ knowledge of, attitudes to and perceptions of ABR. Methods. We conducted a cross-sectional survey of knowledge of, attitudes to and perceptions of ABR among a convenience sample of primary healthcare providers in SA, the majority from the private sector. We used logistic regression to examine associations between knowledge and prescribing behaviours. Results. Of 264 prescriber respondents, 95.8% (230/240) believed that ABR is a significant problem in SA and 66.5% (157/236) felt pressure from patients to prescribe antibiotics. The median knowledge score was 5/7, and scores were highest in respondents aged <55 years (p=0.0001). Prescribers with higher knowledge scores were more likely than those with lower scores to believe that to decrease ABR, narrow-spectrum antibiotics should be used (adjusted odds ratio (aOR) 1.29, 95% confidence interval (CI) 1 - 1.65) and more likely to report that explaining disease features that should prompt follow-up was a useful alternative to prescribing (aOR 1.47, 95% CI 1.058 - 2.04), and were less likely to report that antibiotics cannot harm the patient if they are not needed, so they prescribe when not necessary (aOR 0.57, 95% CI 0.38 - 0.84). Conclusions. Prescribers of antibiotics in the private sector in SA were aware of the problem of ABR, but felt pressure from patients to prescribe. Those with higher knowledge scores reported positive prescribing behaviours, suggesting that more education is needed to tackle the problem of ABR.
