Abstract The purpose of the study was to determine average length of stay (ALOS) for selected surgical procedures for CABG, TKR, THR and inguinal hernia and to compare the variation of ALOS among the group and its comparison with standard guidelines. Passive file auditing method was followed to collect the required information to calculate the pre-operative, post- operative and overall LOS for a period of two months. Additional data was collected from electronic health record system used by the hospital. The observed value for ALOS for CABG was 12.76 days, for TKR – 6.44 days, THR-7.6 days and for inguinal hernia, it came to 2.28 days. Further, the mean and standard deviation with respect to pre-operative and post-operative stay for the four surgical procedures revealed mean pre-operative stay for CABG was 3.96 days, TKR – 1.18 days, THR- 1.60 days and Inguinal hernia was 0.53 days. The post-operative mean stay for CABG, TKR, THR and inguinal hernia were 8.80 days, 4.98 days, 6 days and 1.77 days respectively. It was also observed that there was difference in terms of length of stay (LOS) when compared between male and female patients for different surgical procedures. The findings help in identifying the factors leading to increased LOS number of cases with pre-operative, post-operative or overall stay from entry to exit. It has given an insight on the gaps that needs to address to improve the efficiency of patient services offered by the tertiary care hospital.
