Abstract

Background: In this prospective study of 859 surgical patients in a tertiary research hospital, we examined the association between ASA physical status classification and Intraoperative Therapeutic Intervention Score (I-TIS). Methodology: All patients were assigned by ASA classification before the operation and received a value of 1-4 points for I-TIS score during surgical procedures. Surgical complexity was also classified and correlation with I-TIS was examined. Results: The correlation coefficient of the ASA with I-TIS was r=0.55 (p<0.01). The correlation between the surgical complexity was r=0.66 (p<0.001). Five patients (ASA IV) with I-TIS score>25 and surgical complexity of major plus were admitted to the intensive care unit. Two of them were followed up six hours and the other three stayed more than 24 hours in the intensive care unit. Conclusions: It’s concluded that I-TIS score may be validated for our surgical patients but this assessment may show variability among institutions. The ASA classification is the most valued and widely used scoring system for evaluation of perioperative risk in surgical patients. It is simple, easy and also a useful tool to assist descriptions of workload and ‘anesthetic risk’ for analysis and research purposes.
