Abstract
INTRODUCTION: Delirium is the most common neuropsychiatric condition in very ill patients and those at the end of life. Previous case reports found that delirium-induced disinhibition may lead to overexpression of symptoms. It negatively affects communication between patients, family members, and the medical team and can sometimes lead to inappropriate interventions. Better understanding would result in improved care. Our aim was to determine the effect of delirium on the reporting of symptom severity in patients with advanced cancer. METHODS: We reviewed 329 consecutive patients admitted to the acute palliative care unit (APCU) without a diagnosis of delirium from January to December 2011. Demographics, Memorial Delirium Assessment Scale, Eastern Cooperative Oncology Group (ECOG) Performance status, and Edmonton Symptom Assessment Scale (ESAS) on two time points were collected. The first time point was on admission and the second time point for group A was day one (+two days) of delirium. For group B, the second time point was within two to four days before discharge from the APCU. Patients 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: Ninety-six of 329 (29%) patients developed delirium during their admission to the APCU. The median time to delirium was two days. There was no difference in the length of stay in the APCU for both groups. Patients who did not have delirium expressed improvement in all their symptoms, while those who developed delirium during hospitalization showed no improvement in physical symptoms and worsening in depression, anxiety, appetite, and well-being. CONCLUSION: Patients with delirium reported no improvement or worsening symptoms compared to patients without delirium. Screening for delirium is important in patients who continue to report worsening symptoms despite appropriate management.
