Characteristics and Outcomes of Patients Admitted to the Acute Palliative Care Unit From the Emergency Center

Context. Most patients admitted to acute palliative care units (APCUs) are transferred from inpatient oncology units. We hypothesized that patients admitted to APCUs from emergency centers (ECs) have symptom burdens and outcomes that differ from those of transferred inpatients. Objectives. The purpose of this retrospective cohort study was to compare the symptom burdens and survival rate of patients admitted to an APCU from an EC with those of inpatients transferred to the APCU. Methods. Among the 2568 patients admitted to our APCU between September 1, 2003 and August 31, 2008, 312 (12%) were EC patients. We randomly selected 300 inpatients transferred to the APCU as controls (The outcome data were unavailable for two patients). We retrieved data on patient demographics, cancer diagnosis, Edmonton Symptom Assessment System scores, discharge outcomes, and overall survival from time of admission to the APCU. Results. The EC patients had higher rates of pain, fatigue, nausea, and insomnia and were less likely to be delirious. They were more than twice as likely to be discharged alive than transferred inpatients. Kaplan-Meier plot tests for product-limit survival estimate from admission to APCU for EC patients and inpatients were statistically significant (median survival 34 vs. 31 days, P < 0.0001). In multivariate analysis, EC admission (odds ratio [OR] = 1.8593, 95% confidence interval [CI] 1.1532-2.9961), dyspnea (OR = 0.8533, 95% CI 0.7892-0.9211), well-being (OR = 1.1192, 95% CI 1.0234-1.2257), and delirium (OR = 0.3942, 95% CI 0.2443-0.6351) were independently associated with being discharged alive. Conclusion. The EC patients have a higher acute symptom burden and are more likely to be discharged alive than transferred inpatients. The APCU was successful at managing symptoms and facilitating the discharge of both inpatients and EC patients to the community although the patients had severe symptoms on admission.
