Abstract

Background: Pre-operative investigations are often required to supplement information for risk stratification and assessing reserve for undergoing surgery. Although there are evidence-based recommendations for which investigations should be done, clinical practice varies. There are no clear guidelines regarding preoperative investigations in Tikur Anbesa specialized hospital. The present study aimed to assess the practice of the pre-operative investigations and compare it with the NICE guideline. Methods: Institution based analytic cross-sectional study design was conducted from May to July, 2021.

Data Collected from complete PAC sheets, investigations already done, asked by surgeon/surgery resident, anesthesiologists/ACCPM resident and anesthetist were noted and compared with standard recommendations and guideline (NICE guideline). Data was coded and entered to SPSS version-25 software. Univariet data was expresses in frequency, mean, SD and bivariate data was analyzed using fishers’ exact test, binary and multiple logistic regression. P value less than 0.05 was considered statically significant. Results: Two hundred nineteen (99.5%) questionnaires were collected and analyzed.

ACCPM physicians are more rational in ordering preoperative investigations as compared to surgeons/surgical residents and anesthetists.
