Medical assistance in dying in Canada: A review of regulatory practice standards and guidance documents for physicians.

Background: Medical assistance in dying ("MAiD") became legal across Canada in 2016, and in Québec in 2015. Provincial/territorial regulatory bodies play a critical role in MAiD as they can issue binding requirements on health practitioners. Law and regulatory standards are the "twin pillars" of MAiD regulation, yet the content of MAiD practice standards for physicians is unstudied. Design: This article analysed MAiD guidance for physicians from Canadian medical regulators (often called the "College of Physicians and Surgeons"), using a qualitative descriptive approach, informed by regulatory space theory. Methods: We identified MAiD-specific regulatory documents (practice standards and related documents) using web-based searches and follow-up inquiries. We analysed the documents using qualitative descriptive analysis and the Framework Method, facilitated by NVivo. The analysis focused on identifying areas where regulators issued guidance beyond the law. Results: We identified 15 regulatory documents from 11 of the 13 provinces and territories. We determined that these documents primarily outline the law without detailed guidance on how to apply it. We identified eight areas for which regulators provided guidance that went beyond the MAiD-specific legislation, most relating to core aspects of medical practice, such as competency, documentation, and patient-centred care. The rights and obligations of conscientious objectors were a predominant focus in all documents. The documents largely lacked guidance about the meaning of terms in the legislation. There was also variation in standards between provinces and territories; the documents focused on similar topics but varied in their policy choices. Physicians in each province/territory are therefore subject to differing expectations (to some extent). Conclusion: This study highlights a gap in guidance on the meaning of legal terms in the
