CONSTAIN, Gustavo A. et al. Persistent Delirium in Elderly patients Three Months After Hospital Discharge from a University Clinic. rev.colomb.psiquiatr. [online]. 2018, vol.47, n.1, pp.37-45. ISSN 0034-7450.


The purpose of the study was to determine the prevalence and characteristics of patients with persistent delirium (PD) at three months after hospital discharge.


Longitudinal descriptive study to assess the prevalence and characteristics of in-patients aged 65 years and older in the Clinica Universitaria Bolivariana who met DSM-5 criteria for delirium at admission, at discharge, and at a 3-month follow up assessment. Socio-demographic features were determined, and CGI-S and DRS-R98 scales used.


A total of 30 patients were evaluated between April and October 2013, but 6 did not fulfil the inclusion criteria. The study included 24 patients, with 9 (37.5%) dying during hospitalisation. Of the 15 surviving patients, five (20.8% of the total sample) had their delirium resolved at discharge, and ten (41.6% of the sample) continued with symptoms. These established the PD group, of whom five of them (20.8%) had full PD, and the other five (20.8%) sub-syndromal PD (SSPD). At the final assessment, only two patients (8.3%) continued with full PD, and another two (8.3%) with SSPD. Among the PD group, 30% had a full delirium at admission (prevalence), and 70% developed full delirium during hospitalization (incidence).


A significant number of patients did not recover from delirium at leaving hospital, and remained symptomatic three months after discharge. The study findings suggest a course of gradual improvement of delirium, with a persistence of symptoms over time in 40% of the patients, which would have implications for the clinical practice.
