Adjusted means and incidence rate ratios for 6-month health care use by group

Characteristic	Adjusted mean* (95% CI) matched care plan enrollees n = 548	Adjusted mean* (95% CI) matched controls n = 548	Incidence rate ratio (95% CI) reference group: matched controls
Emergency department visits	2.52 (2.32–2.74)	3.11 (2.87–3.37)	0.81† (0.72–0.91)
Inpatient admissions	0.73 (0.65–0.83)	0.84 (0.74–0.95)	0.87 (0.73–1.04)
Total inpatient length of stay	7.94 (6.39–9.86)	8.02 (6.46–9.96)	0.99 (0.73–1.34)
Acute inpatient length of stay	5.78 (4.71–7.08)	5.78 (4.71–7.08)	1.00 (0.75–1.33)
ALC inpatient length of stay	2.05 (1.18–3.58)	2.19 (1.26–3.81)	0.94 (0.43–2.06)

Note: ALC = alternate level of care, CI = confidence interval.
