Increased symptom expression among patients (PTS) with delirium admitted to an acute palliative care unit (APCU).
56 Background: Previous case reports found that delirium-induced disinhibition may lead to overexpression of symptoms. Our aim was to determine the effect of delirium on the reporting of symptom severity in pts with advanced cancer. Methods: We reviewed 329 consecutive pts admitted to the APCU without a diagnosis of delirium from Jan 2011-Dec 2011. Demographics, Memorial Delirium Assessment Scale (MDAS), ECOG, Edmonton Symptom Assessment Scale (ESAS) on 2 time points were collected. Pts who developed delirium and those who did not develop delirium during the entire course of admission were compared using Chi-Squared test and Wilcoxon rank-sum test. Paired t-test was used to assess if the change of ESAS from baseline to follow-up was associated with delirium. Results: 96/329 (29%) of pts developed delirium during their admission to the APCU. The median time to delirium was 2 days. There was no difference in the length of stay in the APCU for both groups. Table 1 shows the changes in the ESAS scores of the two groups from baseline to follow-up. Pts who did not have delirium expressed improvement in all their symptoms while those who developed delirium during the hospitalization showed no improvement in physical symptoms and worsening in depression, anxiety, appetite and wellbeing. Conclusions: Pts with delirium reported no improvement or worsening symptoms as compared to pts without delirium. Screening for delirium is important in pts who continue to report worsening symptoms despite appropriate management. [Table: see text]
