RESUMO
OBJECTIVES: What are the Canadian public's understanding of and views toward medical assistance in dying (MAID) in persons refusing recommended treatment or lacking access to standard treatment or resources? DESIGN/SETTING: An online survey assessed knowledge of and support for Canadian MAID law, and views about four specific scenarios in a two (medical or psychiatric) by two (treatment refusal or lack of access) design. PARTICIPANTS: A quota sample (N=2140) matched to the 2021 Canadian census by age, gender, income, education and province. MAIN OUTCOMES: Participants' level of support for MAID in general and in the four specific scenarios. RESULTS: Only 12.1% correctly answered ≥4 of 5 knowledge questions about the MAID law; only 19.2% knew terminal illness is not required and 20.2% knew treatment refusal is compatible with eligibility. 73.3% of participants expressed support for the MAID law in general, matching a nationally representative poll that used the same question. 40.4% of respondents supported MAID for mental illnesses. Support for MAID in the scenarios depicting refusal or lack of access to treatment ranged from 23.2% (lack of access in medical condition) to 32.0% (treatment refusal in medical illness). Older age, more education, higher income, lower religious attendance or being white was associated with greater support for MAID in general but was either negatively associated or not associated with support for MAID in the four refusal or lack of access scenarios. CONCLUSIONS: Most Canadians support the current MAID law but appear unaware that MAID cases they do not support are compatible with that law. The lower support for MAID in the four scenarios cuts across sociodemographics. The gap between current policy and public opinion warrants further study. For jurisdictions debating MAID, opinion surveys may need to go beyond assessing general attitudes, and target knowledge and views regarding implications of legalisation.
