knowledge, attitudes and practice of nurses regarding adverse drug reaction reporting

background : adverse drug reactions (adr) are ranked as some of the major causes of patient morbidity and mortality. spontaneous reporting of adrs has remained the cornerstone of pharmacovigilance and is important in maintaining patient safety. this study was conducted to assess the nurses’ knowledge and attitude towards pharmacovigilance, reasons for not reporting adrs, and their pharmacovigilance practice. methods : a questionnaire was prepared to investigate knowledge, attitude and practice (kap) of nurses regarding adr reporting. in november 2009, the questionnaires were given to 500 nurses of a teaching hospital in tehran. results : knowledge and practice of participants were not satisfying; however, their attitude towards pharmacovigilance was at a high level. about 91% of the nurses had never reported an adr. most nurses liked to report the adrs to the physicians (87.1%) and pharmacists in hospital’s adr center (1.8%) rather than the adr national center. the main cause of under-reporting of the suspected adrs was unawareness about the existence of such a national center. among nurses who had reported adr for at least once, the majority preferred using phone (10 out of 50) or yellow cards (7 out of 50). only 1 person out of 50 preferred using internet for submitting the reports. conclusions : since the nurses in this study had little knowledge and poor practice regarding the pharmacovigilance and spontaneous reporting system, interventions such as holding pharmacovigilance workshops in the hospitals focusing on the aims of pharmacovigilance, completing the yellow card and clarifying the reporting criteria are strongly recommended. key words : knowledge, attitude, practice, nurse, adverse drug reaction, pharmacovigilance, iran.
