Backround. Based of my personal observations when employed as a pharmacist in a Saudi hospital it was clear that there were problems with medicine supply to outpatients. This thesis was designed to scientifically investigate the types of shortages, the reason(s) for such problems and potential solutions to the problem. Methods . This study was undertaken using a variety of experimental techniques to determine the views and perceptions of patients, pharmacists, physicians and administrative staff of the hospital under examination. To establish the scale of the problem: focus groups (n=25), structured questionnaires, structured interviews/meetings for health care professionals and a national survey (n=650) were the research tools used to objectively determine the relevant data. The data were analyzed by appropriate statistical methods. Results and Discussion That there was a real problem was quickly established in the data obtained from patients. A similar finding was made for each of the 'professional groups'. The central problem was one of shortages of medicines for prescriptions presented by outpatients. It was not a case the medicines were simply not available because they were never stocked but rather a simple shortage in the dispensary stock. It was established the lack of medicines was not due to central budget arrangements but involved prescribing quantities outside of the hospital guidelines which no degree of planning could accommodate. There was also the very unexpected finding that a prescription could be filled in a variety of hospital dispensaries as individuals could access more than one hospital or they could consult more than one physician for the same condition and obtain effectively double the supplies. Communications between the hospital and patients and the health care professionals could all be improved by perhaps increasing the knowledge of the patient about the correct use of medicines. Recommendations. A series of recommendations for future work is provided
