Surviving Long Enough to Die? An Analysis of Incomplete Assessments for Medical Assistance in Dying.

Background: Medical assistance in dying (MAiD) was legalized in Canada on June 17, 2016, yet many who request MAiD do not complete the assessment process and instead experience a natural death. This analysis of patients who made a formal request for MAiD aims to clarify timelines and factors associated with completion of the MAiD assessment process, and factors associated with completion or noncompletion of MAiD once eligible. Materials and Methods: This retrospective cohort study included all patients in Nova Scotia who requested MAiD between January 1, 2018 and December 31, 2018, were deceased at the time of analysis, did not withdraw their request, and were not formally deemed ineligible for the procedure (n = 218). Descriptive statistics, Kaplan-Meier curves, and logistic regression were used in data analysis. Results: Of 218 patients, 48 did not complete the MAiD assessment process. Of the 170 patients who completed the assessment process and were deemed eligible for MAiD, 79.4% (n = 135) completed the procedure. Those with an incomplete assessment had a median survival from request to death of 8.0 days (interquartile range [IQR] = 11.5), whereas for those deemed eligible, median survival from request to determination of MAiD eligibility was also 8.0 days (IQR = 16.0). Interpretation: Proximity to natural death and poor performance status at the time of MAiD request may drive incomplete MAiD assessments. The majority of patients deemed eligible for MAiD complete the procedure, and as such, patients who did not complete the MAiD assessment process may not have experienced their preferred mode of death.
