Associations of Intellectual Disability with Cardiopulmonary Resuscitation and Endotracheal Intubation at End of Life.

Little is known about end-of-life intensive care provided to patients with intellectual disabilities (ID). To identify differences in receipt of end-of-life cardiopulmonary resuscitation (CPR) and endotracheal intubation among adult patients with and without ID and examine whether do-not-resuscitate orders (DNRs) mediate associations between ID and CPR. Exploratory matched cohort study using medical records of inpatient decedents treated between 2012 and 2018. Patients with ID ( = 37) more frequently received CPR (37.8% vs. 21.6%) and intubation (78.4% vs. 47.8%) than patients without ID ( = 74). In multivariable models, ID was associated with receiving CPR (relative risk [RR] = 2.92, 95% confidence interval = 1.26-6.78,  = 0.012), but not intubation. Patients with ID less frequently had a DNR placed (67.6% vs. 91.9%), mediating associations between ID and CPR. In this pilot study, ID was associated with increased likelihood of receiving end-of-life CPR, likely due to lower utilization of DNRs among patients with ID. Further research is needed to confirm these results.
