Abstract: Background: Intensity Modulated Radiation Therapy (IMRT) is a method of delivering high-dose radiation to tumours while sparing surrounding healthy tissues. Despite its wide availability IMRT utilization varies across Ontario. The study’s objective was to examine key steps in the implementation process and identify factors that facilitate or impede IMRT implementation. Research Methods: An embedded multiple case study design, utilizing document analysis and key-informant interviews, was employed. Four cancer centres were selected and key-informant interviews were conducted with radiation oncologists, physicists, radiation therapists, and administrators. Results: Eighteen of 21 invited key-informants participated (86% participation rate) providing a range of insights on the factors influencing IMRT implementation. Overall, three cases made progress in the implementation of IMRT, while one case had limited implementation over the same time period. Conclusion: These findings help explain the observed variation in IMRT implementation across Ontario, which is multifaceted and reflects ongoing processes of change and reinvention.
