    Objetivo: Hallar la validez pron贸stica de 铆ndice de fibrosis-4 para la mortalidad en pacientes con enfermedad hep谩tica cr贸nica Materiales y m茅todo: se realiz贸 un estudio anal铆tico transversal, cohorte retrospectiva a partir de historias cl铆nicas, se us贸 el programa STATA versi贸n 15.2; se analiz贸 la normalidad de la variable cuantitativa, para la asociaci贸n entre la puntuaci贸n del FIB-4 y la presencia de mortalidad se us贸 regresi贸n log铆stica en modelos crudos y ajustados con las variables intervinientes en mortalidad. Resultados: Se revisaron las historias cl铆nicas de 320 pacientes, de las cuales se incluyeron 313 debido a los criterios de selecci贸n. Se realiz贸 un modelo de supervivencia, se encontr贸 que los pacientes con un tiempo de enfermedad mayor ten铆an menor probabilidad a morir durante el tiempo de hospitalizaci贸n actual. Se encontr贸 una sensibilidad del 56,25% para la escala MELD a comparaci贸n del 92,54% de Fib-4, mientras que una especificidad mayor para la escala MELD a comparaci贸n que su contraparte para la mortalidad general. El 谩rea bajo la curva ROC seg煤n la mortalidad general para FIB 4 fue de un valor de 0.8477 mientras que para MELD result贸 en 0.8649. Conclusiones: la escala FIB-4 y MELD son v谩lidas para la predicci贸n de mortalidad en los pacientes con enfermedad hep谩tica cr贸nicaObjective: To find the prognostic validity of fibrosis index-4 for mortality in patients with chronic liver disease. Materials and method: a cross-sectional analytical study was carried out, a retrospective cohort from medical records, using the STATA program version 15.2; the normality of the quantitative variable was analyzed, for the association between the FIB-4 score and the presence of mortality, logistic regression was used in crude models and adjusted with the variables intervening in mortality. Results: The medical records of 320 patients were reviewed, of which 313 were included due to the selection criteria. A survival model was carried out, it was found that patients with a longer illness time were less likely to die during the current hospitalization time. A sensitivity of 56.25% was found for the MELD scale compared to 92.54% for Fib-4, while a higher specificity for the MELD scale compared to its counterpart for general mortality. The area under the ROC curve according to general mortality for FIB 4 was 0.8477 while for MELD it was 0.8649. Conclusions: the FIB-4 and MELD scale are valid for the prediction of mortality in patients with chronic liver disease.Tesi
