BACKGROUND: Pharmacovigilance is an important part of the health care system as it helps in the detection, assessment, reporting and prevention of Adverse Drug Reactions. Spontaneous reporting of adverse drug reaction plays a vital role in the success of Pharmacovigilance programs and pharmacy students are supposed to acquire sufficient knowledge and necessary skills required for practicing pharmacovigilance under different clinical settings. Hence, this study was carried out in the students of College of Pharmacy of a University in the Southern Province of Saudi Arabia to assess the Knowledge, Attitude and Practice (KAP) of undergraduate Pharmacy students towards Pharmacovigilance. METHODS: A quantitative, prospective, cross-sectional online survey was carried out using a validated, self-administered questionnaire constituting 4 domains i.e. Demographics, Knowledge, Attitude and Practice of Pharmacovigilance among the pharmacy students of King Khalid University. RESULTS: The questionnaire was administered to 360 students out of which 329 responded (response rate of 91.3 %). The mean score of Level 7,8,9,10 and intern students for Knowledge was (3.03,5.37, 6.38, 6.19,6.42), Attitude (5.28,4.16, 5.62, 5.01, 5.29), and Practice (2.99, 3.25, 3.04, 3.43, 3.13) respectively. In addition, the findings indicated a significant difference in the mean score among different level of students for knowledge and attitude with a p-value of <0.0001, and 0.0002 respectively. The practice mean score showed there was no much significance among different level of students (p-value = 0.4108) CONCLUSION: Our research findings revealed that the pharmacy students of the focused university have adequate knowledge and positive attitude towards adverse drug reaction. However, there is a dire need to understand and address concerns regarding real time practice patterns prevalent among Health Care Providers about pharmacovigilance under different clinical settings.
