[영문]Purpose.The attitudes of pharmacy residents toward pharmaceutical industry promotion and the perceived effects of such promotion on the knowledge and professional practice of the residents were studied.Methods.A questionnaire study of current postgraduate year 1 and postgraduate year 2 pharmacy residents was conducted. Questions were adapted from instruments used in studies of medical student or physician attitudes regarding the pharmaceutical industry. The questionnaire requested demographic information about the resident, information regarding the resident’s exposure to specific types of pharmaceutical company-related activities, and the resident’s perception of whether the residency program or department had policies or guidelines regarding interactions with the pharmaceutical industry. Questions investigated the attitudes toward pharmaceutical industry promotion and the perceived influence of pharmaceutical industry promotion on the professional knowledge and behavior of the residents.Results.Reponses were received from 496 pharmacy residents. Nearly all (89%) residents agreed that pharmaceutical company-sponsored educational events enhance knowledge. Almost half (43%) of the respondents reported that information from educational events influences therapeutic recommendations. One quarter (26%) of the pharmacy residents indicated prior training regarding pharmacist?industry interactions, and most (60%) residents indicated that their institution’s residencies or departments have policies regarding interactions with the pharmaceutical industry.Conclusion.Most surveyed pharmacy residents believed that educational events sponsored by pharmaceutical companies enhance knowledge. Respondents whose institutions had policies or who had received training about such events were less likely than other respondents to perceive an influence of the events on their knowledge and behavior.
