Hepatitis C in the three main health institutions in Mexico: a 13-year mortality and hospitalization analysis

There are no studies in Mexico comparing Hepatitis C virus (HCV) epidemiology among Health Institutions. In this report, we described the deaths and hospitalizations due to HCV in the three main Health Institutions in Mexico: the Mexican Institute of Social Security, the Institute of Social Security for State Workers and the Ministry of Health, during the period 2004-2017. A secondary analysis was carried out across the country using hospital administrative death databases. Adult deaths and hospitalizations rates were calculated in reference to the total affiliated population and all-cause in-hospital mortality risk were also evaluated. There were 7,914 deaths and 9,002 hospitalizations due to HCV. Mortality and hospitalization rates of these three institutions together showed a continuous decrease over the analyzed time: the mortality rate dropped from 1.25 to 0.41 per 100,000 affiliates during 2004 and 2017, respectively (66.9% of change), and the hospitalization rate dropped from 2.19 to 0.39 per 100,000 affiliates (81.9% of change). All-cause in-hospital survival accounted for 89.6%. Older age groups and Ministry of Health hospitalizations were associated with higher all-cause in-hospital death rates. In conclusion, the mortality and hospitalizations rates found in this study reflect a decrease in the burden of HCV in Mexico.
