Multivariate Poisson Regression Models for Health Care Utilization in the Four Subgroups.

Variables	Adjusted ORa (95% CI)
	Coexisting dementia and cancer	Dementia only	Cancer only
Number of hospitalization	1.69 [1.69, 1.80]**	1.63 [1.56, 1.69]**	1.12 [1.07, 1.17]**
Among those hospitalized
Number of hospital readmissions within 30 days	1.36 [1.15, 1.60]**	1.43 [1.28, 1.60]**	1.09 [0.96, 1.24]*
Number of intensive care unit use	1.02 [0.90, 1.19]**	1.19 [1.09, 1.32]**	0.95 [0.88, 1.04]**
Number of ED visits	1.42 [1.36, 1.48]**	1.33 [1.30, 1.37]**	1.00 [0.98, 1.03]
Number of physician care visits	1.42 [1.36, 1.48]	1.33 [1.30, 1.37]*	1.00 [0.98, 1.03]**
Number of days in nursing home	1.22 [1.20, 1.24]**	1.40 [1.38, 1.42]**	0.86 [0.85, 0.88]**
Number of days in hospice	0.76 [0.74, 0.78]**	0.91 [0.90, 0.93]	0.57 [0.56, 0.59]**

Note. OR = odds ratio; CI = confidence interval; ED = emergency department; SES = socioeconomic status.

^aReference group is “Neither dementia nor cancer”; models were adjusted for age, race, sex, state subsidy status (SES indicator), medical comorbidities, and location.
