[Factors associated with in hospital deaths in a hemodialysis population in Peru]

To determine the factors associated with mortality during the first hospitalization of patients admitted to a hemodialysis unit.

Observational and retrospective study of patients admitted to "Dos de Mayo" National Hospital between January 2012 and December 2013. For the survival analysis we used the Kaplan-Meier method. A multivariate logistic regression was performed to evaluate the factors associated with hospital mortality.

216 patients with a mean age of 56.9 ± 15.5 years were studied. 24% of patients (n = 51) died during their hospital stay. The mortality rate was 9.3 deaths/100 person-weeks (95% CI: 7.0 to 12.3). We found a tendency of less risk of death in patients with between 1 and 6 months from chronic kidney disease diagnosis (OR 0.84, 95% CI: 0.32 to 2.26) and in those with more than six months from chronic kidney disease diagnosis compared with those who had less than a month from chronic kidney disease diagnosis (OR 0.55, 95% CI: 0.19 to 1.57). Previous care by a nephrologist was not associated with differences in lower mortality (OR 1.14, 95% CI: 0.39 to 3.31).

There is poor prior care among hemodialysis patients that form part of an inadequate health care structure and this is associated with high inhospital mortality.
