Healthcare workers have a main role in detection, assessment and spontaneous reporting of adverse drug reactions (ADRs), and improvement of their related knowledge, attitude and perception is essential. The goal of this study was evaluation of clinical pharmacists' interventions in improvement of knowledge, attitude and perception of healthcare workers about ADRs in a teaching referral hospital, Tehran, Iran.
Changes in knowledge, attitude and perception of healthcare workers of Imam teaching hospital about ADRs were evaluated before and after clinical pharmacists' interventions including workshops, meetings and presentations.
From the 100 participated subjects, 82 of them completed the study. 51% of the health workers have been aware of the Iranian Pharmacovigilance Center at the ministry of health before intervention and after that all the participants knew this centre. About awareness and detection of ADRs in patients, 69 (84.1%) healthcare workers recognised at least one, and following interventions, it was improved to 73 (89%). Only seven (8.5%) subjects have reported ADRs in before intervention phase that were increased significantly to 18 (22%) after intervention.
Clinical pharmacists' interventions were successful in improvement of healthcare workers' knowledge, attitude and perception about ADRs and spontaneous reporting in our hospital.
The goal of this study was evaluation of clinical pharmacists' interventions in improvement of knowledge, attitude and perception about adverse drug reactions in a referral teaching hospital, Tehran, Iran.
Our results showed that 91.5% of the healthcare workers of the hospital never reported any adverse drug reaction and 49% were not even aware of the Iranian Pharmacovigilace Center.
Identifying previously unrecognised adverse drug reactions was the most important goal for adverse drug reaction reporting in before and after the interventions phases of the study.
Regarding the study results, it was suggested that health systems must have training programmes for their workers about importance, detection, analysis, reporting and fallow-up of adverse drug reactions in the hospital and provide online and telephone line accesses to facilitate adverse drug reactions reporting system.
Strengths and limitation of this study
To the best of our knowledge, this is the first survey in Iran that have evaluated clinical pharmacists' interventions in improvement of the healthcare professionals' knowledge, attitudes and perceptions regarding adverse drug reaction.
