The validated Advance Care Planning (ACP) Engagement Survey includes both self-reported Behavior Change and Action Scores. Percentages reflects participants with positive slopes over time, adjusted for health literacy, baseline ACP documentation, and clustering by physician.
“All ACP Activities” is a composite measure of Behavior Change and Action scores. We present slopes for all reported ACP activities as well as ACP documentation-specific and ACP discussion-specific activities. To specifically assess engagement in ACP discussions or documentation, we categorized ACP Engagement Survey items into those related to Discussions (i.e. survey item referred to “ask” or “talk”) and Documentation (i.e. survey item referred to “signing” or “documenting”).
Statistical significance set at p=0.017 to account for multiple comparisons for the three outcomes of improvement in behavior change or action, behavior change only and action only. No additional p-value adjustments were made for analyses stratified by language as these were pre-specified.
