Table 3.

Living in community refers to residence outside a nursing home at 100 days following index PAC facility discharge. Number of different living situations is calculated at 1 year. Logistic regression used to calculate odds ratios was adjusted for age, gender, Charlson-Deyo score, and index hospitalization length of stay.

a. Association of readmission with patient outcomes
Outcome	Readmitted (95% CI)	Not readmitted (95% CI)	P-value
Living in community (%)	45.1 (41.5–48.7)	64.9 (63.0–66.8)	<0.001
Different living situations (mean)	5.4 (5.3–5.6)	3.4 (3.3–3.5)	<0.001
Mortality at 30 days (%)	18.9 (16.1–21.8)	8.6 (7.5–9.7)	<0.001
Mortality at 100 days (%)	39.9 (36.4–43.5)	14.5 (13.1–15.9)	<0.001

b. Association of readmission with patient outcomes
Outcome	Unadjusted OR (95% CI)	Adjusted OR (95% CI)
Living in community	0.44 (0.44–0.52)	0.52 (0.44–0.62)
Different living situations, >2 versus 2 or less	13.96 (5.16–37.73)	13.15 (4.86–35.58)
Mortality (30 days)	2.18 (1.75–2.72)	2.01 (1.60–2.54)
Mortality (100 days)	3.92 (3.26–4.72)	3.79 (3.13–4.59)
