Public versus Private Healthcare Systems following Discharge from the ICU: A Propensity Score-Matched Comparison of Outcomes

Table 1

Comparison of baseline characteristics of critical care patients discharged from tertiary hospitals according to healthcare system status.

Variables	All cohort; ()	Private healthcare group; ()	Public healthcare group; ()	value
Male gender, (%)	499 (53.7)	401 (53.0)	98 (56.9)	0.39
Age, years, mean ± SD	63.7 ± 17.6	65.7 ± 17.3	55.3 ± 16.7	<0.001
Number of comorbidities, mean ± SD	1.4 ± 1.2	1.5 ± 1.2	1.2 ± 1.1	0.02
ICU admission APACHE-II, mean ± SD	14.9 ± 6.6	14.7 ± 6.6	15.9 ± 6.6	0.03
Mechanical ventilation during ICU stay, (%)	324 (34.9)	248 (32.8)	76 (40.9)	0.006
RRT during ICU stay, (%)	67 (7.2)	46 (6.0)	21 (12.2)	0.008
ICU day of discharge SOFA score, mean ± SD	0.8 ± 1.6	0.7 ± 1.5	1.28 ± 1.8	<0.001
ICU day of discharge TISS-28 score, mean ± SD	11.6 ± 4.6	11.6 ± 4.5	11.4 ± 4.9	0.16

Note. The comorbidities included heart failure, ischemic heart disease, cerebrovascular disease, diabetes mellitus, chronic obstructive pulmonary disease, cirrhosis, HIV infection, chronic renal failure, and malignant neoplasia.
SD: standard deviation; ICU: intensive care unit; APACHE-II: acute physiology and chronic health evaluation-II score; RRT: renal replacement therapy; SOFA: sequential organ failure assessment score; TISS-28: simplified therapeutic intervention scoring system.
