In February 2015, the Supreme Court of Canada ruled that it was unconstitutional to prohibit physicians from assisting in a patient's consensual death, thereby setting the groundwork for the legalization of medical assistance in dying (MAiD). Much of the research on this topic has focused on physicians, although other health care professionals will be involved in the process, including pharmacists, pharmacy technicians, and pharmacy assistants. In many provinces, the medications required for MAiD will be dispensed from hospital pharmacies, which will result in direct involvement of hospital pharmacy staff. The primary objective was to investigate the knowledge and attitudes of hospital pharmacy staff in Canada regarding MAiD. The secondary objective was to determine the factors that might influence those opinions. A 34-question web-based survey was available for 6 weeks during early 2017 to hospital pharmacy staff throughout Canada. For most questions, responses were based on a 5-point Likert scale, ranging from "strongly agree" to "strongly disagree". Descriptive and inferential statistics were used to analyze the data. A total of 1040 valid survey responses were received: 607 from pharmacists, 273 from pharmacy technicians, and 160 from pharmacy assistants. Most respondents were supportive of MAiD; however, nearly all respondents (99% [601/607] of pharmacists, 73% [315/431] of technicians and assistants]) reported lacking comprehensive education on the topic. Despite high levels of overall support, pharmacists tended to be less supportive of MAiD than pharmacy technicians or assistants. Factors that influenced opinions included strong religious beliefs, region, and knowledge of provincial and federal legislation. The majority of respondents, particularly technicians and assistants, were supportive of MAiD, but most respondents lacked education about the topic.
