Objective: To assess knowledge, extent of reporting and factors influencing reports of adverse drug reactions (ADRs) by resident doctors.
Study design and setting: Study site was the University College Hospital (UCH), Ibadan, an 850-bed tertiary care hospital in western Nigeria. It was a cross-sectional survey. Data were collected with a 46-item self-administered questionnaire from 192 clinical physicians.
Results: Older aged doctors, senior cadre and doctors in medical faculty were 1.5 times likely to be aware of ADR reporting guidelines. General knowledge on ADR was good while 58.3% of residents knew the burden of ADRs. Most (89.5%) had observed at least one ADR but only 32% had ever reported it. Residents in medical faculty were twice more likely to report ADRs than the surgeons [OR 2.1; 95%CI 1.1, 4.1]. The commonest factors that militate against ADR reporting were lack of knowledge that reporting forms were available (70.9%) and ignorance of reporting procedure (69%).
Conclusion: Despite high observation and good knowledge of ADR among doctors, the rate of reporting was low. There is need for publicity of activities of the pharmacovigilance unit of the hospital.
