Prescreening of Patient-reported Symptoms using the Edmonton Symptom Assessment System (ESAS) in Outpatient Palliative Cancer Care
Abstract Background: Although early palliative care is associated with a better quality of life and improved outcomes in end-of-life cancer care, the criteria of palliative care referral are still elusive. Methods: We collected patient-reported symptoms using the Edmonton Symptom Assessment System (ESAS) at the baseline, first, and second follow-up visit. The ESAS evaluates ten symptoms: pain, fatigue, nausea, depression, anxiety, drowsiness, dyspnea, sleep disorder, appetite, and wellbeing. A total of 71 patients were evaluable, with a median age of 65 years, male (62%), and the Eastern Cooperative Oncology Group (ECOG) performance status distribution of 1/2/3 (28%/39%/33%), respectively. Results: Twenty (28%) patients had moderate/severe symptom burden with the mean ESAS ≥5. Interestingly, most of the patients with moderate/severe symptom burdens (ESAS ≥5) had globally elevated symptom expression. While the mean ESAS score was maintained in patients with mild symptom burden (ESAS<5; 2.7 at the baseline; 3.4 at the first follow-up; 3.0 at the second follow-up; P =0.117), there was significant symptom improvement in patients with moderate/severe symptom burden (ESAS≥5; 6.5 at the baseline; 4.5 at the first follow-up; 3.6 at the second follow-up; P <0.001). Conclusions: Advanced cancer patients with ESAS ≥5 may benefit from outpatient palliative cancer care. Prescreening of patient-reported symptoms using ESAS can be useful for identifying unmet palliative care needs in advanced cancer patients.
