Comparison of Proxy and Self-Reported Functional Ability in Heart Failure Patients with Cognitive Impairment.

Background: Heart failure (HF) patients often experience cognitive impairment that negatively impacts self-management ability, predisposing these individuals to worse post-hospitalization outcomes. Patient proxies may have more insight into a patient's self-management capability especially in the context of patient cognitive impairment. Here, we incorporate proxy input to evaluate associations between patient- and proxy-reported capacity for instrumental activities of daily living (IADL) stratified along a patient's cognitive function in an older hospitalized heart failure population.
