Abstract

The study was done to assess the efficiency of Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score in predicting post-operative pulmonary complications (PPC) in esophagectomy patients at a tertiary cancer care hospital by retrospective analysis. We included patients belonging to ASA II and III categories who underwent esophagectomy at our institution during June 2016 to June 2017. Patients with missing data were excluded from analysis. The medical records of these patients were reviewed to obtain data. The seven-factors of ARISCAT score were recorded from the medical records. The occurrence of post-operative pulmonary complications and length of stay were also recorded from the medical records. Statistical analysis was done using SPSS software (version 11.0).  Fisher’s exact test, chi-square test, Logistic regression and Kaplan-Meier analysis were used. Among the study group 16 patients out of 19 belonging to the high risk ARISCAT category (84.2%) and 8 out of 24 patients (33.3%) of intermediate risk group had PPC (P =0.002). From the logistic regression analysis there is a ten times increased risk of PPC developing in patients falling in the high-risk category of ARISCAT than those in intermediate risk category (OR=10.667, 95%CI 2.387-47.659, P= 0.002). Pre-operative SpO2, anaemia, respiratory infection in last month and age showed a positive correlation for development of PPC in the high-risk category compared with the intermediate risk category. ARISCAT risk score has a good practical applicability in pulmonary risk stratification of esophagectomy patients and should be explored further.
