How Tailoring Led to Variation in Care Issues, Dosage, and Outcomes: Part 1: Secondary Analysis of the PREP Trial for Frail Older Adults and Family Caregivers.

Abstract

In family caregiving interventions for adults with health problems, tailoring has become the norm. Studies that evaluate tailored interventions, however, have rarely included intentional variation in dosage or explored the dosage-outcome association. In this Part 1 secondary analysis, we examine dosage and outcomes in intervention families (N = 116) who participated in the Oregon Health & Science University/Kaiser Permanente Northwest Region Family Care Study. The Family Care Study was a randomized controlled trial to evaluate the preparedness, skill, enrichment, and predictability (PREP) intervention with caregiving families of frail older adults referred for skilled home health. Tailoring of PREP began with assessment by the PREP nurse. Families then identified and selected care-related issues to work on with their PREP nurse; family needs and preferences guided the number and timing of nurse visits and calls. Families selected a median of 3 (range = 0 to 10) care-related issues in five categories: direct care (chosen by 57% of families), transitions (40%), caregiver strain and health (40%), arranging care (33%), and enrichment (22%). The number of issues strongly predicted number of PREP nurse visits and calls, whereas nurse visits in turn predicted caregivers' reports of improved family care and usefulness of home health assistance, highlighting the importance of visits for achieving outcomes.
