ABSTRACT
OBJECTIVE: To investigate the effectiveness of the Adverse Drug Reaction (ADR) Prevention Program. MATERIAL AND METHOD: This cross-sectional study is quasi-experimental with in- and out-patients. Data was collected over a period of six months on patients' histories, basic knowledge of ADR prevention, and their attitudes toward the prevention program. The effectiveness of the program was evaluated by assessing patient knowledge before, immediately after and one month after the completion of the program. RESULTS: Sixty-five volunteers were enrolled in the present study. A comparison of patient knowledge before and immediately after implementation of an ADR Prevention Program showed significant differences (p < 0.05), as did a comparison of patient knowledge before and one month after the program. Personnel involved in hospital services and patient education expressed positive attitudes towards the program. CONCLUSION: The ADR Prevention Program has produced some positive results in patients' knowledge, awareness, and attitudes toward the program at Rasisalai Hospital, Srisaket, Thailand.
