Perceptions and realities : medical and surgical procedure variation : a literature review Sheps, Samuel Barry; Scrivens, S; Gait, Jennifer Mary


We undertook an in-depth literature review with the overall goal of assessing the current state of knowledge of procedure variations in medical and surgical practice with particular reference to research attempting to assess the impact of specific variables on the variation observed. Our explicit objectives were to review the recent literature using explicit a priori criteria in order to: 1) identify papers using sound methodology; 2) determine the magnitude of variation found to exist and whether there is consistency in this estimate across studies; 3) determine, in general and for specific procedures, which factors seem consistently related to variations (if any); and 4) identify directions for future research.
