Objective:
The purpose of this study was to determine if our predictive scoring system, E-PASS, can estimate the surgical outcome.
Methods:
We conducted a multicenter cohort study for 3 years in four national hospitals. A consecutive series of 731 patients who underwent elective thoracic operations were analyzed. The preoperative risk score (PRS) and the comprehensive risk score (CRS) of the E-PASS were determined preoperatively and immediately after the operation, respectively. The cost of the surgical admission and the severity of the postoperative complications were recorded at the time of discharge.
Results:
The CRS significantly correlated with the severity of the postoperative complications (rs = 0.728, P < 0.0001) and the charge (rs = 0.530, P< 0.0001). When the estimated/real morbidity ratio (MR) among the hospitals was compared, it varied from 0.16 to 0.59. A significant increase in the cost was observed according to the CRS.
Conclusion:
The E-PASS scoring system may be useful for standardizing the patient population and surgical severity to compare the surgical outcome.
