Physicians attending an interactive session at the 1988 Annual Scientific Assembly of the ACCP answered a series of questions about the diagnosis and management of patients with hemoptysis. Responses were recorded by computer, and the proportions of answers to multiple-choice questions were tabulated for immediate feedback to the audience. Participants selected a single best answer most consistent with their personal views. In addition to an overall summary, the responses entered from individual data entry keypads could be recorded and related to one another. Thus, with the assumption that each keypad represented the views of a single physician, the approaches of clinicians with particular characteristics could be compared. Statistical analyses of such comparisons were performed by means of the chi square test or Student s f-test, with p<0.05 regarded as statistically significant.
