Abstract
BACKGROUND
The South African National Drug Policy (SA-NDP) was introduced to promote rational medicine use (RMU). This study evaluates the quality of prescribing in the public healthcare sector in South Africa's Limpopo province following the World Health Organization's (WHO) rational prescribing standards. In addition, the prescribing practices in South Africa were compared to other African countries.
METHODS
A prospective cross-sectional survey of patients' prescriptions was conducted in Limpopo, South Africa, from October to December 2018. Findings were compared with the WHO reference values (WHO-RV), and the International Network of Rational Use of Drugs (IRDP) tool was used to measure the degree of rational prescribing. The optimal IRDP value was defined as 1. Study findings were compared with results from a previous study conducted in Limpopo and studies from Ethiopia and Eritrea.
RESULTS
Six hundred prescriptions were reviewed. The mean (SD) age was 43.9 ± 24.4 years (females = 56.5%). The average number of drugs prescribed (4.3, IRDP = 0.47) was higher than the WHO-RV (< 2). Generic prescribing (43%, IRDP = 0.43) and medicines prescribed from the essential medicines list (EML) (90%, IRDP = 0.90) were less than the WHO-RV (100%, respectively). Antibiotics (28%, IRDP = 1) and the number of injections prescribed (8%, IRDP = 1) were below the WHO-RV (< 30% and < 20%, respectively). The number of medicines prescribed was higher compared to previous years (4.3 vs. 3.4). Antibiotic prescribing declined (28% vs. 63.4%). Generic prescribing (43% vs. 41.7%) and medicines prescribed from the EML (90% vs. 93.1%) did not improve. A higher number of medicines were prescribed in this study compared to Ethiopia (1.7) and Eritrea (1.8), and a lower number of antibiotics were prescribed compared to Ethiopia (58.2%) and Eritrea (54.5%). Generic prescribing was low compared to Ethiopia (95.6%) and Eritrea (94.9%). All studies showed reduced injection prescribing (6.6-15.9%) and similar prescribing from the EML (90-95%).
CONCLUSIONS
There is an increased potential for drug-drug and adverse reactions with the increased number of prescribed medicines; however, the patient's clinical needs may warrant using multiple medicines. There is a need for generic prescribing to reduce medicine expenditure.
