RESUMO
OBJECTIVE: This study was performed to determine whether students who are trained in developing a personal formulary become more competent in rational prescribing than students who have only learned to use existing formularies. METHODS: This was a multicentre, randomised, controlled study conducted in eight universities in India, Indonesia, the Netherlands, the Russian Federation, Slovakia, South Africa, Spain and Yemen. Five hundred and eighty-three medical students were randomised into three groups: the personal formulary group (PF; 94), the existing formulary group (EF; 98) and the control group (C; 191). The PF group was taught how to develop and use a personal formulary, whereas e the EF group was taught how to review and use an existing formulary. The C group received no additional training and participated only in the tests. Student's prescribing skills were measured by scoring their treatment plans for written patient cases. RESULTS: The mean PF group score increased by 23% compared with 19% for the EF group (p < 0.05) and 6% for controls (p < 0.05). The positive effect of PF training was only significant in universities that had a mainly classic curriculum. CONCLUSION: Training in development and use of a personal formulary was particularly effective in universities with a classic curriculum and with traditional pharmacology teaching. In universities with a general problem-based curriculum, pharmacotherapy teaching can be based on either existing or personal formularies.
