Patient age, years‡	0.99 (0.97–1.0)	0.17	0.99 (0.97–1.0)	0.21
Weekend day of call (vs. weekday) ‡	0.49 (0.24–1.0)	0.05	0.52 (0.21–1.3)	0.16
Patient location prior to admission‡
Home	1	-	1	-
Different acute care center	1.2 (0.56–2.6)	0.63	1.7 (0.69–4.0)	0.26
Intermediate or long-term center	7.2 (1.5–35.7)	0.02	8.1 (1.5–43.8)	0.02
Charlson comorbidity index‡	1.2 (1.0–1.4)	0.02	1.3 (1.1–1.5)	0.004
Call time after 5 p.m. (vs. before) ‡	2.2 (0.77–6.1)	0.14	2.3 (0.63–8.7)	0.20

Note: only inaccurate communications and potential confounders were included in the multivariable model.
