BackgroundHospitalization is an inherently serious event in the oldest-old, as the risk of complications associated with it increases exponentially with age and can lead to death. Despite the size of the problem, few studies have been dedicated to determining mortality predictors among hospitalized older patients, particularly among the oldest-old. Objectives: To examine in-hospital mortality predictors in the oldest-old adults hospitalized in an acute geriatric ward.MethodsWe retrospectively surveyed electronic hospital health records of 977 elderly patients, aged  90 years, admitted between January 2007 and December 2010 from the emergency department to the acute geriatrics department. We compared the characteristics of the patients who survived to those who died during the hospital stay.ResultsThe patients mean age was 93.4 years. In-hospital mortality rate was about 11.6%. Mortality predictors were female sex, on-admission pneumonia, co-morbid congestive heart failure and cerebrovascular accident, high troponin I levels, lower levels of albumin, and higher level of urea (P = 0.032, P < 0.0001, P = 0.0015, P = 0.0049, P = 0.0503, P < 0.0001 and P < 0.0001, respectively). Consumption of  5 drugs and the number of hospitalizations in the last year were inversely associated with death (P = 0.0145 and P < 0.0001, respectively).ConclusionsCareful evaluation of mortality predictors might be useful for therapeutic planning and identification of potential inpatients for specific interventions. Awareness of in-hospital mortality predictors might contribute to reducing in-hospital death.
