Table 2 Outcomes for the intervention and control groups

Outcomes	Intervention group (n = 93)	Control group (n = 144)	Statistical test for the difference^a
HoNOS difference at discharge^b: median (IQR^c)	-8 (8)	-8 (8)	z = -0.345
Treatment length: median (IQR)	36 (23.5)	27 (17)	z = -3.251**
Readmission within 2 years^d, n(%)	46 (49.5)	74 (51.4)	χ² (1) = 0.084
Number of readmission days^e: median (IQR)	41 (56.8)	52 (62.5)	z = 0.254

^a χ² test for categorical variables. Mann–Whitney test for continuous variables; the 95% confidence intervals for p-values used to assess statistical significance were estimated using the Monte Carlo method based on 10′000 samples
^b The HoNOS difference at discharge corresponds to the difference between the total HoNOS score at discharge and the total HoNOS score at admission. Data were missing for 8 patients in the intervention group and 21 in the control group
^c IQR = Interquartile range
^d Readmission within 2 years indicates if a patient was readmitted to the CPC and/or to CRHT at least once during the 2 years period following discharge
^e The number of readmission days corresponds to the total number of inpatient/CRHT days related to single or multiple readmissions during the 2 years period following discharge. Data were available for 39 patients in the intervention group and 74 in the control group
^*p-value < 0.05, ** p-value < 0.01, *** p-value < 0.001
