Abstract:

BACKGROUND: Pain, dyspnea, and depression are highly troubling near the end of life. OBJECTIVE: To characterize factors associated with clinically significant pain and the presence of dyspnea and depression during the last year of life in a nationally representative sample. DESIGN: Retrospective cohort study. SETTING: Health and Retirement Study, a national sample of community-dwelling US residents aged 51 and older. PARTICIPANTS: Family respondents of 8254 decedents who died between 1998 and 2012. MEASUREMENTS: Clinically significant pain often during the last year of life; dyspnea and depression for at least one month during the last year of life. RESULTS: Life support was associated with dyspnea (odds ratio [OR] 1.71, 95% confidence interval [CI] 1.42-2.06) and depression (OR 1.20, CI 1.04-1.39), treatment for cancer with pain (OR 1.65, CI 1.41-1.92), and oxygen for a lung condition with dyspnea (OR 14.78, CI 11.28-19.38). More diagnoses were associated with dyspnea (OR 1.24, CI 1.17-1.30) and depression (OR 1.14, CI 1.08-1.21). More activities of daily living (ADL) dependencies were associated with clinically significant pain (OR 1.06, CI 1.03-1.09), dyspnea (OR 1.06, CI 1.02-1.10), and depression (OR 1.10, CI 1.07-1.12), and more instrumental activities of daily living (IADL) dependencies with depression (OR 1.12, CI 1.08-1.18). Worse self-rated health was associated with pain (OR 0.83, CI 0.77-0.88), dyspnea (OR 0.89, CI 0.84-0.95), and depression (OR 0.83, CI 0.78-0.89). Arthritis was associated with clinically significant pain (OR 2.24, CI 1.91-2.63). CONCLUSIONS: Factors associated with common, burdensome symptoms in a national sample suggest clinical and population strategies for targeting symptom assessment and management.
