GRADUATE medical education is one of the core missions of academic medical centers, wherein medical specialists are responsible for teaching and supervising their future colleagues. However, being a medical specialist is no longer a sufficient qualification or proxy for competence in medical education aimed at training residents. This is particularly true given the modernization requirements for competency-based teaching and training promoted by accreditation institutions in some countries (such as the Accreditation for Council for Graduate Medical Education in the United States). These modernization efforts accelerate faculty development of clinicianeducators needed to achieve and maintain the highest standard of postgraduate medical education. An effective faculty development track should include measuring medical teaching effectiveness. This requires valid and reliable instruments, as well as providing the findings in a clear and concise format to faculty. Several studies have found that systematic and constructive feedback can result in improved teaching. There are few published and validated evaluation systems or even instruments aimed at supporting the graduate medical education qualities of clinical faculty. In anesthesiology, there are few published instruments and systems, and the existing ones tend to focus on faculty evaluation by residents only without any self-evaluations by faculty. To ensure actual behavioral change, individuals must usually undergo a stepwise change process. Evaluation insights obtained from feedback should be followed by creating positive intentions to change, trying out new behaviors and integrating them into practice. Supporting this change process has been shown to be effective. To support the specialty-specific evaluation of teaching qualities of anesthesiology faculty in an academic medical center, we developed the System for Evaluation of Teaching Qualities (SETQ) comprising (1) a Webbased self-evaluation by faculty, (2) a Web-based residents’ evaluation of faculty, (3) individualized faculty feedback, and (4) individualized faculty follow-up support. This paper has three main objectives: (1) to investigate the psychometric properties of the two instruments underlying the SETQ system, (2) to explore the relationship between residents’ evaluation and faculty self-evaluation, and (3) to gauge the feasibility of reliably using residents’ evaluation of faculty by estimating the number of such evaluations needed per faculty. We also place these objectives in context by describing SETQ. SETQ was initially developed in the anesthesiology department of a large academic medical center that has over 7,000 staff (including about 500 faculty and 400 residents) in the Netherlands. It was later expanded to include specialty-specific modules for internal medicine, surgery, and obstetrics and gynecology. At the time of writing, most of the remaining specialties have signed up for SETQ, resulting in more than 90% faculty coverage in 2009. SETQ is receiving nationwide attention.
