Improving drug use through continuing education: a randomized controlled trial in Zambia.
The objective of this study was to evaluate the impact of three continuing education seminars (within a period of 4 months) on the quality of patient management and rational drug use. The study was designed as a randomized controlled trial. Prescribers in 16 general health centers were allocated to an intervention (eight health centers) or a control (eight health centers) group. A total of 5,685 patient cards was analyzed for quality of case management and rational drug use. In the intervention health centers the average number of drugs per patient decreased from 2.3 to 1.9 (p = 0.005) and the proportion of patients managed with nonpharmacological treatment increased from 1 to 13.2%. Recorded history taking, examination, and diagnosis improved in the intervention health centers. More drugs were correctly chosen in the intervention health centers compared to control health centers (p = 0.03). The proportion of patients prescribed antibiotics decreased and the proportion of patients adequately managed increased in the intervention health centers. Our conclusion is that continuing education in the form of repeated seminars is effective in influencing prescribers and in promoting rational drug use in primary care.
