Associations Between Time-Varying Exposures and Admission to Hospice in Last Year of Life
| Time-Varying Exposure | Unadjusted Hazard Ratio (95% CI) | Adjusted a Hazard Ratio (95% CI) |
|---|---|---|
| Specific month b | ||
| Any restricting symptoms | 1.62 (1.27–2.07) | 1.66 (1.30–2.12) |
| Per no. restricting symptoms c | 1.08 (1.04–1.12) | 1.09 (1.05–1.12) |
| Per no. disabilities d | 1.10 (1.05–1.14) | 1.10 (1.05–1.14) |
| Cumulative number of months e | ||
| Any restricting symptoms | 1.07 (1.01–1.12) | 1.07 (1.01–1.13) |
Abbreviation: CI, confidence interval.
a
Covariates included age, sex, race/ethnicity, years of education, living situation, number of chronic conditions, cognitive impairment, depressive symptoms, low social support and months since prior comprehensive assessment.
b
Results reflect the marginal (i.e. average) effect of each exposure at month t-1 on hospice admission at month t.
c
Possible range: 0 to 15
d
Possible range: 0 to 13
e
Results reflect the effect of each additional month with any restricting symptoms as a time-varying exposure (up to month t-1) on hospice admission at month t.
