Background In June 2016, the Parliament of Canada passed federal legislation allowing eligible adults to request Medical Assistance in Dying (MAID). Since its implementation, there likely exists a degree of hesitancy among some healthcare providers due to the law being inconsistent with personal beliefs and values. It is imperative to explore how nurses in Quebec experience the shift from accompanying palliative clients through “a natural death” to participating in “a premeditated death.” Research question/aim/objectives This study aims to explore how Quebec (...) nurses personally and professionally face the new practice of MAID and their role evolution. Research design A grounded theory design was used. Participants and research context We recruited 37 nurses who participated in or coordinated at least one MAID. Semi-structured interviews and focus groups were conducted and audiotaped. Data collection and analysis followed Strauss and Corbin steps. Ethical considerations Ethics approval was received from the investigator’s affiliated University. Participants were informed regarding the research goal, signed a written consent, and were assigned pseudonyms. Findings/results Results show that nurses experienced the wide range of paradoxe during MAID centering around the following eight elements: 1) confrontation abouth death, 2) choice, 3) time of death, 4) emotional load, 5) new Bill, 6) relationship with the person, 7) communication skills, and 8) healthcare setting. The shifting of views and values in this new role is presented by the contradiction of opposites. Conclusions A better understanding of the paradox experienced by nurses involved with MAID paves the way for the development of interventions. (shrink)
