Disparities in Advance Directive Documentation for Rural-Dwelling Persons With Lung Cancer.

Purpose: Advance directives (AD) are recommended for persons with lung cancer, yet few studies have investigated AD and healthcare power of attorney (HCPOA) documentation for this population in rural regions of the United States. The purpose of this study was to examine demographic and clinical factors associated with AD and HCPOA documentation for persons with lung cancer in rural eastern North Carolina (ENC). Methods: A cross-sectional retrospective chart review was conducted to collect demographic and clinical data from electronic health records from 2017 to 2021 at a tertiary cancer center and regional satellite sites in ENC. Descriptive statistics and Chi-Square Tests of Independence were used for data analysis. Findings: The sample's mean age was 69.5 years (n = 402, SD = 10.5, range = 28 - 92). Most participants were male (58%) and had a smoking history (93%). Consistent with regional population statistics, 32% of persons were black, and 52% lived in rural counties. Just 18.5% of the sample had a documented AD and 26% had a healthcare power of attorney. Black persons had significantly lower AD and HCPOA (P < .001) documentation than white persons. Rural-dwellers had significantly lower HCPOA documentation than urban-dwellers (P = .03). For all other variables, no significant differences were found. Conclusions: These findings suggest that AD and HCPOA documentation are low for persons with lung cancer in ENC, particularly for black persons and rural-dwellers. This disparity highlights the need for enhanced advance care planning (ACP) access to and outreach in the region.
