e24073 Background: Understanding the experience of individuals with cancer (pts) who utilize Medical Aid in Dying (MAID) is important given growing access and limited research in the U.S. Methods: Chart review from January 1, 2014-October 1, 2020, of all pts who inquired (but did not initiate completion of all legal requirements), initiated (but did not complete all legal requirements to obtain access to the medications), or completed all legal requirements and could have had access to medications (whether or not they were obtained or used) at Seattle Cancer Care Alliance/University of Washington. Chi-square tests were used to compare differences in pt characteristics between the inquired/initiated versus completed group. Results: Of 498 total pts, 116 (23.3%) inquired, 127 (25.5%) initiated, and 255 (51.2%) completed the MAID process, of which, 45.9% (117/255) were known to have used the medications. At time of first inquiry (FI), mean age was 66 years (standard deviation [SD] = 11.9)/median 67.3/range 22-94; 206 (41.4%) were female; and 40 (8.0%) were non-white, while 11 (2.2%) were Hispanic/Latino and 14 (2.8%) were non-English speaking. At FI, 292 (58.6%) pts were married or had a significant other; 152 (30.5%) had a religious affiliation; 23 (4.6%) were uninsured; and 282 (56.6%) had Medicare. Mean months from the original cancer diagnosis and FI was 36.5 (SD = 50.3, range 0.1-366.1). 461 (92.6%) pts had solid/central nervous system (CNS) tumors, of which 231 (46.4%) had presented with metastatic disease. At FI, 84 (16.9%) were currently hospitalized; in total, 236 (47.4%) pts had been hospitalized within the 3 months prior to FI. A total of 71.9% (358/498) had not yet initiated hospice at FI; 51.8% (258/498) had evidence of advance care planning (ACP), including 41.5% (107/258) with a Physician Order for Life Sustaining Treatment on file. Overall, 152 (30.5%) and 166 (33.3%) of pts had seen social work or palliative care in the 30 days prior to FI, while 62 (12.4%) had met with a spiritual health clinician. Statistically significant differences were found between those who inquired/initiated versus completed with the following pt characteristics: non-white (ꭓ2= 6.596, p = .010); Medicaid versus all other insured (ꭓ2= 9.489, p = .002); those hospitalized at FI (ꭓ2= 6.101, p = .014); and those without evidence of ACP (ꭓ2= 17.090, p < .001). Pts with a hematologic malignancy (HM, n = 37/498, 7.4%) were less likely to complete the MAID process compared to pts with solid/CNS tumors (ꭓ2= 7.378, p = .007); 43.2% (16/37) of HM pts did not complete due to rapid decline. Conclusions: Less than half of pts who initially inquired about MAID completed the process. Recent hospitalizations and evidence of ACP were relatively common compared to current utilization of hospice or prior use of supportive care services. Future research should investigate why non-white pts, those with Medicaid and those with HM may be less likely to complete the MAID process.
