Research Objectives The purpose of this project is to synthesize the existing intelligence regarding the management of waiting times for specialized and diagnostic services in an effort to identify the key local and contextual factors of successful waiting time management. [...] One of the key recommendations of the literature has been the development of reliable and comparable waiting time data for a broad range of medical procedures so that patients, healthcare providers and governments can have a more accurate understanding of the extent and nature of waiting times15. [...] In some jurisdictions, a distinction has been drawn between Wait Time 1: the general practitioner’s referral to the specialist and Wait Time 2: the time between the visit to the specialist and the surgery itself. [...] The volume of literature related to the determinants of organizational change is extensive and the conceptualization of the parameters that an organization can change varies by author38. [...] It states the questions addressed by the review, outlines the methods developed for our search strategy, explains the selection criteria, the data extraction and the data synthesis processes, and presents the findings and key results.
