Surrogate decision-makers from historically marginalized populations have lower levels of preparedness for care planning.

Abstract

Surrogate preparedness for medical decision-making is an important part of care planning. This study examined preparedness and engagement among historically marginalized surrogates. Surrogates were included if they were named medical decision-makers by patients ≥55 years at a San Francisco safety-net and Veterans Affairs hospital. We assessed preparedness for medical decision-making by asking if surrogates had been formally asked to be the medical decision-maker, if patients had discussed medical wishes with surrogates, and if the surrogate role and these medical wishes had been documented. We assessed surrogate confidence and readiness using a modified Surrogate ACP Engagement Survey. We used Wilcoxon rank-sum tests to measure the association of engagement scores with surrogate characteristics. Of 422 surrogates, their mean age was 53 years (SD ±14.5), 73% were from minoritized groups, 38% were Spanish-speaking, and 15% had limited health literacy. For preparedness outcomes, 13% of surrogates were not formally asked to play this role, 46% reported the patient had not discussed end-of-life medical wishes, and 51% reported there had been no formal documentation of the surrogate role. Surrogates reported higher confidence 4.43/5 (SD ± 0.64) than readiness 3.70 (1.22) for decision-making (p < 0.001). Confidence and readiness scores were lower among historically marginalized participants. More resources are needed to prepare surrogate decision-makers from historically marginalized communities for discussing patient's goals of care and treatment preferences.
