INTRODUCTIONA prescription is "a written order, which includes detailed instructions of what medicine should be given to whom, in what formulation and dose, by what route, when, how frequently, and for how long.1 Ordering a valid and complete prescription requires a thorough knowledge and understanding of patho-physiology of disease, the pharmacological properties of the relevant drugs, and the ways in which the two dovetail.
2The drug-related components of a prescription include both inscription (i.e. appropriateness of drug(s) selected, strength, dosage form, quantity to be dispensed) and signtura (i.e. direction for use). The inscription and signtura are deemed to be the most challenging part of the prescription writing skill to be achieved by preclerkship medical students in both problem-based learning curriculum and traditional curriculum. [3][4][5][6] Acquisition of therapeutic reasoning and prescribing competency, as a clinical skill, has been reported to be sub-optimal among students in preclerkship phase and junior doctors, regardless of the curriculum strategy used in medical schools. [3][4][5][6][7][8][9][10] At the College of Medicine and Medical Sciences (CMMS), Arabian Gulf University (AGU), we have introduced a pharmacotherapeutic context learning program in order to develop the prescription writing competency of medical students at the preclerkship phase through a total of 16-hour educational interactive sessions. The program is interrupted thereafter during clerkship phase, assuming that the students" prescription writing competency would be further enhanced at realworld prescribing setting.
ABSTRACTBackground: Medical school training for students in pharmacotherapy is suboptimal and junior doctors are not confident to prescribe drugs. This study was conducted to assess the prescribing competency of students in preclerkship and clerkship phases at a medical school that implements problem-based learning curriculum. Methods: Objective structured practical examination was used to assess prescribing competency of students in both phases. The prescribing performance was empirically categorized into poor, moderate and good competency.
Results:The prescription writing skills achieved by the clerkship students did not significantly differ from that attained by students in preclerkship phase. Good prescribing competency was attained by approximately 20% of the students at the end of both phases. Preclerkship students performed better on therapeutic reasoning than those in clerkship phase. Cognitive skill that involves choosing the superior drug(s) among several alternatives as achieved less satisfactorily by majority of students from both phases of the program. Conclusions: Acquisition and further development of the prescribing competency during the clerkship phase was sub-optimal. The continuation of pharmacotherapeutic context-learning program during clerkship phase is recommended.
