Background: Patients ≥80 with implantable cardioverter-defibrillators (ICDs) have high rates of hospitalization and mortality, yet few have documented advance directives. We sought to determine the prevalence of advance directives in adults ≥80 years with ICDs, focusing on those with frailty and cognitive impairment.
Methods: Prospective cohort study (July 2016-May 2019) in an electrophysiology clinic. Presence of advance directives (health care proxies [HCP] and living wills [LW], or medical orders for life-sustaining treatment [MOLST]) was determined by medical record review. Frailty and cognitive impairment were screened using 4-m gait speed and Mini-Cog.
Results: 77 Veterans were evaluated. Mean age 84 years, 100% male, 70% frail. Overall, 52 (68%) had an HCP and 37 (48%) had a LW/MOLST. Of 67 with cognitive testing, 36% were impaired. HCP documentation was similar among frail and non-frail (69% vs. 65%). LW/MOLST was more prevalent among frail versus non-frail (52% vs. 39%). There was no difference in HCP documentation by cognitive status (67%). A LW/MOLST was more frequent for cognitively impaired versus non-impaired (50% vs. 42%). Among 19 Veterans who were frail and cognitively impaired, 14 (74%) had an HCP and 11 (58%) had a LW/MOLST.
Conclusions: Most Veterans had a documented advance directive, but a significant minority did not. Simple frailty and cognitive screening tools can rapidly identify patients for whom discussion of advance directives is especially important.
