Validated Tool for Quality Assessment of Anesthesia Services by Cardiac Surgeons

BACKGROUND AND AIM: The role of the cardiac anaesthesiologists extends beyond mere patient wellbeing to diagnostic input and active participation in decision making during cardiac surgery. The quality of service provision should therefore be judged not only by patient satisfaction but also by the satisfaction of cardiac surgeons. Unfortunately, quantification of cardiac surgeon satisfaction remains a challenge due to the absence of a reliable and validated tool. We therefore attempted to develop a robust, validated, pilot psychometric questionnaire, to measure satisfaction of cardiac surgeons' to cardiac anesthesia services. METHODS: The questionnaire was developed with the help of senior cardiac anesthesiologist, cardiac surgeon and statistician with database search in PubMed and the Cochrane Library. The questionnaire was tested for content validity, comprehensibility, and identification of new items. This generated the second version of the questionnaire with nine socio-demographic and professional questions, 46 Likert type questions, an abridged Marlowe Crowne Social Desirability scale and one open ended question. This questionnaire was e-mailed to 100 cardiac surgeons requesting them to participate via a web-based survey application. RESULTS: Content validity of the responses was tested by Aiken's content validity coefficient (V). Internal consistency was tested with Chronbach's alpha. Fifty-two cardiac surgeons participated in the survey. Twelve Likert type questions were deleted due to low V values. Excellent Chronbach's alpha (0.94) was obtained in the remaining 34 items. CONCLUSIONS: We have developed a questionnaire that includes 34 variables and allows quantifying surgeon satisfaction in a reliable fashion and is validated for the purpose.
