RESUMO
Background and Aim: The deleterious effects of Resident Doctors' (RDs') long duty hours are well documented. Driven by concerns over the physician's well-being and patient safety, the RDs' duty hours in many developed countries have been capped. However, in Nigeria and many African countries, there are no official regulations on work hours of RDs. This study evaluated the work schedule of Nigerian RDs and its impact on their wellbeing and patient safety. Subjects and Methods: A national survey of 1105 Nigerian RDs from all specialties in 59 training institutions was conducted. With an electronic questionnaire designed using Google Forms, data on the work activities of RDs were obtained and analyzed using the IBM SPSS software version 24. The associations were compared using Chi-squared test with the level of significance set at < 0.05. Results: The mean weekly duty hours (h) of the RDs was 106.5 ± 50.4. Surgical residents worked significantly longer hours than non-surgical residents (122.7 ± 34.2 h vs 100.0 ± 43.9 h; P < 0.001). The modal on-call frequency was two weekday on-calls per week (474, 42.9%) and two weekend on-calls per month (495, 44.8%), with the majority of RDs working continuously for up to 24 hours during weekday on-calls (854, 77.3%) and 48-72 hours during weekend on-calls (568, 51.4%), sleeping for an average of only four hours during these on-calls. The majority of RDs had post-call clinical responsibilities (975, 88.2%) and desired official regulation of duty hours (1,031, 93.3%). Conclusion: The duty hours of Nigerian RDs are currently long and unregulated. There is an urgent need to regulate them for patient and physician safety.
