Predictors of Advance Care Planning in Older Women: The Nurses' Health Study.

Abstract

Relatively little is known regarding predictors of advance care planning (ACP) in former nurses. We aimed to evaluate potential predictors of ACP documentation and discussion. Cross-sectional study, 2012-2014. Nurses' Health Study. A total of 60,917 community-dwelling female nurses aged 66 to 93 years living across the United States. Based on self-reports, participants were categorized as having (1) only ACP documentation, (2) ACP documentation and a recent ACP discussion with a healthcare provider, or (3) neither. Multivariable log-binomial models were used to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) of the two separate ACP categories vs those with neither. We evaluated various demographic, health, and social factors. The large majority (84%) reported ACP documentation; 35% reported a recent ACP discussion. Demographic factors such as age and race were associated with both ACP categories. In multivariable analyses, race was most strongly associated: compared with whites, African Americans were 27% less likely (PR = 0.73; 95% CI = 0.69-0.78) to report ACP documentation alone and 41% (PR = 0.59; 95% CI = 0.54-0.66) less likely to report documentation with discussion. Additionally, health/healthcare-related characteristics were more strongly associated with ACP documentation plus discussion. Women with functional limitations (PR = 1.15; 95% CI = 1.10-1.20), women who were recently hospitalized (PR: 1.10; 95% CI = 1.08-1.12) or women who had seen a physician for health symptoms (PR = 1.43; 95% CI = 1.35-1.52) or screening (PR = 1.40; 95% CI = 1.32-1.49) were more likely to report having both ACP documentation and discussion. Social factors showed limited relationships with ACP documentation only; for documentation plus discussion, being widowed and living alone was associated with higher prevalence (PR = 1.21; 95% CI = 1.19-1.24) and having little emotional support was associated with lower prevalence (PR = 0.84; 95% CI = 0.81-0.86). Among older nurses, most of whom reported having documented ACP, 35% reported recent patient-clinician ACP discussions, indicating a major participatory gap in an element critical to ACP effectiveness. Even in nurses, African Americans reported less ACP documentation or discussion. J Am Geriatr Soc 67:292-301, 2019.
