A survey was undertaken to assess the knowledge, attitude and practice of medical ethics among surgical residents and interns in three teaching hospitals of Karachi, Pakistan. 101 out of 120 completed responses were included in the study. Fifty-one respondents had heard about the Code of Ethics formulated by the Pakistan Medical and Dental Council. Forty-four had read the code. Seven had no knowledge about it. Forty-seven reported taking consent for procedures. Forty-two respondents gave correct answers on questions of confidentiality and knowledge of law pertaining to trauma victims. Only 11 reported having been taught ethics as students. Four did not feel the need of its teaching at an undergraduate level. Doctors graduating within the last 10 years gave fewer correct answers than those graduating earlier. Knowledge of medical ethics and its application on the surgical floors is extremely poor. The survey results support the view that medical ethics should be a part of the undergraduate medical curriculum
