Assessing physicians' roles on health care ethics committees.

The purpose of this study was to examine the role of physicians on HEC including structural and process features. Four committees were selected from among 12 volunteering to participate with 12 sessions observed. Power analysis (0.8) confirmed an adequate number of communication exchanges, and no statistical significant difference (p < 0.05) among two prior surveys affirmed the sample. Data collection included established questionnaires and communication analyses with a tested method. Results revealed physician presence was robust and similar to prior reports on HEC structure; however, physicians rated their role effectiveness lower than other occupations and lower than overall committee effectiveness. Communication exchanges representing process revealed three positive communication types, and consistent attempts to aid committee functions through consensual processes that also were substantiated by non-physician members. Findings suggested more attention to both structural and process functions of HEC and their members.
