The paper reports results of an assessment of knowledge and practice of medical ethics among nurses in a public hospital before and after an intervention training module on medical ethics. Its objective was to provide baseline information about ethical knowledge and practice in a public hospital and investigate the feasibility of improvement using a 1-day seminar-workshop. The results of the study were to be used to formulate policies on ethical training for healthcare workers. A questionnaire on the basic ethical principles and practices will be prepared. Respondents were presented with case scenarios. They were asked to choose the best among 3-4 approaches to resolving the ethical problem(s) in each scenario. The questionnaire was administered a few hours before the workshop on ethics. The participants were asked to complete the same questionnaire within 1  month of the ethics workshop. To make sure that responders give honest answers, no personal identifiers were included on the questionnaires. They will however be asked to invent a code of their own and write that code on the pre and post-intervention questionnaires to enable statistical analysis. The investigators will not know to whom the codes belong. Data was key-punched and analyzed using the SPSS program. Conditional logistic regressions methods will be used to derive odds ratios with 95% confidence intervals after adjusting for confounders.
