The high worldwide prevalence of non-alcoholic fatty liver disease (NAFLD); which can progress from simple hepatic steatosis to non-alcoholic steatohepatitis (NASH), and finally to liver cirrhosis. This research arises from the need for a timely and non-invasive diagnosis of NASH. Objective: To evaluate the diagnostic performance of the NI-NASH-DS score for the detection of non-alcoholic steatohepatitis in obese adults who are candidates for bariatric surgery, during the years 2017-2020, treated at the Avendaño clinic, in Lima, Peru. Methodology: Cross-sectional descriptive observational study corresponds to an external validation of a score using the information recorded in a database of patients undergoing bariatric surgery, from a private clinic, located in Lima, Peru. To carry out the external validation, the linear predictor was calculated for each patient based on the score equation. Subsequently, we proceeded with the evaluation of the general performance, the discriminative capacity and the calibration; with their respective 95% confidence intervals. Results: A final sample of 417 was analyzed, revealing that 95.7% (n=399) had a NASH diagnosis vs. Not NASH; In addition, it was shown that 94.8% (n=254) were women and 97.5% (n=307) performed physical activity. Likewise, in our population, the AUC analysis of the NI-NASH-DS revealed a low discriminative capacity with AUC of 0.66 (95% CI: 0.53 - 0.76), the Briar score showed a good general performance of 0.44 (95% CI %: 0.02 - 0.06) and adequate calibration of 0.478 through the Test, Hosmer - Lemeshow. Conclusion: No significant relationship was found between the NI-NASH-DS score and the detection of NASH. Likewise, we believe that adding an additional test to this score could more accurately detect non-alcoholic steatohepatitis.
