Background: Inadequate communication between professionals in operating theaters results in impaired medical performance or even in critical events. Interprofessional case seminars, however, can enhance team communication by promoting a deeper understanding of complex situations. Our aim was to evaluate how an interprofessional case seminar using a dual professional focus case in anesthesiology was perceived by the participants. Method: A case seminar was held for 20 nurse anesthetists enrolled in a postgraduate course and for six anesthesiology residents. Transcripts of the case were distributed in advance for individual study and group discussion. The evaluation was based on the responses provided by participants who completed a semistructured questionnaire and from the perceptions of a professional observer. Results: Twenty participants completed the questionnaire; 53% of the respondents had previous experience with case methodology, and 89 different statements were obtained. Of these, 48% were positive and 11% were negative. The remaining 40% of the statements related to previous experiences with case methodology and to suggested improvements. The positive statements proposed that case methodologies are suitable for sensitive issues and beneficial for meetings and exchanges between different professionals. Negative statements focused instead on lack of time, overly large groups, too much speculation, and inadequate preparation or presentations by the participants. Conclusion: Interprofessional case seminars using a dual professional focus may be suitable for postgraduate education in anesthesia. This technique may improve interprofessional communication and may call attention to the importance of soft issues, such as ethics, communication, organization, and leadership in addition to that of the medical dimension.
