[Impaired cognitive function as an independent risk factor for the in-hospital mortality in the elderly with XXXX ].

@entity712 ( @entity712 ) and @entity73 are frequent causes of hospitalization in elderly @entity1 . Independently, both clinical syndromes are associated with increased mortality. The aim of the study was to evaluate the influence of @entity73 on in-hospital mortality in old @entity1 with @entity712 . A modified Mini-Mental State Exam (MMMSE) was performed in 598 consecutive @entity1 (65-102 years old; 355 female) with @entity712 . All @entity1 were stratified into low (6.3 +/- 1.2 points), medium (19.7 +/- 4.7 points) or high (29.1 +/- 2.1 points) tertile group according to MMMSE results. Total in-hospital mortality was 52.0% in the lowest, 34.2% in the medium and 15.1% in the highest tertile (Pearson Chi-square p < 0.0001 for trend). The comparison of in-hospital mortality between tertiles of MMMSE was done with the use of logistic regression adjusted to age, sex, and the presence of @entity6 , @entity177 and @entity417 . Comparison of in-hospital mortality between @entity1 from the lowest tertile of MMSE with the highest one revealed that odds ratio was 5.93 (95% CI: 3.58-9.80; p < 0.0001) whereas it was 2.67 (95% CI: 1.60-4.67; p = 0.0002) for @entity1 from the medium tertile. The obtained results show that the worse cognitive function is, the worse in-hospital prognosis can be observed in older @entity1 with @entity712 . Moreover, it also suggests that @entity73 may be an independent risk factor for mortality in elderly @entity712 @entity1 .
