Abbreviations: CI, confidence interval; CPR, cardiopulmonary resuscitation; OR, odds ratio; POLST, Physician Orders for Life-Sustaining Treatment.

a

Adjusted for all exposures presented in the table.

b

Educational attainment was converted from an eight-category variable to approximate number of years of formal education, and modeled continuously.

c

The Washington State POLST specifies that the POLST should always be signed by the patient unless the patient is “decisionally incapacitated,” in which case a legal surrogate may sign the POLST.

d

OR reflects the change in odds per twofold increase in days from POLST to death.

e

Date of POLST completion is modeled as number of days since January 1, 2000, divided by 365.
