Association of Weighted and Unweighted Care Utilization on Caregiver Quality of Life (Logistic Regression Models) (N = 522)

	Caregiver Self-Rated Health	Caregiver Burden	Caregiver Depressive Symptoms
	Fair/Poor (32.9%)	High (40.8%)	High (29.6%)
	(missing = 7)	(missing = 6)	(missing = 9)
	6-Month Utilization of Care Recipient

Note. Model coefficients (coef.) and estimated marginal effects (EME) derived from analysis on full training set (n = 365), minus cases with missing data. EMEs represent the average effect of one day of utilization on the increased (or decreased) probability of a negative Quality of Life (QoL) outcome. For continuous utilization variables, EME were calculated based on original unstandardized scales. Missing values resulted in row-wise deletion. ED = emergency department, IP = inpatient hospitalization, PAC = post-acute care facility.

^aFemale caregivers represent reference group.

^bCaregivers 18–55 years represent reference group.

^dCaregivers caring for someone other than spouse represent reference group.

^eWhite caregivers represent reference group.

^fCaregivers with more than high school education represent reference group.

^gRural veterans represent reference group.
