A study has been undertaken of 52 "charts review" cases (postmortem) formally discussed by Resident Staff of the Department of Medicine, University College Hospital, Ibadan at meetings over a period of 24 months. The senior registrars' diagnosis were correct in 39 (75%) cases while the registrars diagnosis were correct in 34 (64.4%) cases. The senior registrars were correct more often than the registrars; though the difference between them was not statistically significant (x2-1.14, P = n.s).
