Outcomes In complex patients with delirium and subsyndromal delirium one year after hospital discharge

摘要

There has been an increasing interest in delirium as a clinical syndrome in elderly patients in the last years (de Rooij et ah, 2005). Until now the diagnosis has been dichotomous, but recent studies appear to show that a further categorization of this syndrome may lead to a higher diagnostic and prognostic value. The subsyndromal delirium (SSD) displays some of the symptoms without developing the full syndrome and it is intermediate in severity between non-delirious controls and full syndromal delirium, although it has no officially recognized diagnostic criteria (Levkoff et al, 1996). There is growing evidence about the prognostic significance of SSD among elderly individuals, but to date there are very few published studies on SSD in elderly patients. The goal of our study was to corroborate one-year outcomes after discharge.
