Objective: This study aims to reveal whether a short training course of problem-based pharmacotherapy teaching, based on the World Health Organization's (WHO's) Guide to Good Prescribing and the Yemen Essential Drug List and Standard Treatment Guidelines, will improve the competence of rational prescribing among medical and health assistant students in Yemen.
Design: In a controlled pre/post-test study, 111 students from universities and health institutes participated on a voluntary basis. They were randomly separated into a study and a control group. Students of the study group were taught to generate standard first-choice drugs for asthma or diarrhoea. The students were then taught how to apply this set of first-choice drugs to specific patient problems, using the WHO six-step problem-solving approach.
Results: Students from the study group performed significantly better than those from control in all problems presented and also when compared with the results of the pre-test. The results of the pre-test also show that teaching students all basic knowledge about drugs does not guarantee rational prescribing in Yemen.
Conclusion: It can be concluded from this study that proper training, i.e. 'immunising' future doctors using problem-based pharmacotherapy teaching, is an efficient way of teaching rational prescribing in Yemen.
