SEDANO, Carlos et al. Efficacy of the Manheim´s index in patients with secondary peritonitis in a hospital in Huancayo, Peru. Rev Med Hered [online]. 2019, vol.30, n.1, pp.12-19. ISSN 1018-130X.  http://dx.doi.org/10.20453/rmh.v30i1.3467.

Objectives: To determine the efficacy of the Manheim´s index in predicting mortality in patients with secondary peritonitis. Methods: A retrospective diagnostic like study was carried-out with data extracted from clinical charts. A non-probabilistic sampling of 294 patients of whom 40 had died and 254 were discharged alive after being surgically intervened from secondary peritonitis in the General Surgery service at Hospital Daniel Alcides Carrion in Huancayo was calculated using EPIDAT 4.1. Sensitivity, specificity, predictive values, likelihood ratios and ROC curves and area under the ROC were calculated. Results: A Manheim´s index of e"26 showed a sensitivity of 0.85, specificity of 0.972, positive predictive value of 0.829 and negative predictive value of 0.976. The optimal threshold was e"21 attaining a sensitivity of 0.975. The area under the ROC curve was 0.976. Conclusions: Manheim´s index is a good predictor of mortality among patients with secondary peritonitis, the optimal threshold was e"21.
