Background: Due to high symptom burden in advanced cancer patients, ongoing symptom management for outpatient palliative care patients is vital. More patients are receiving outpatient care; Yet, most palliative care patients receive less than 2 follow ups. Nurse telephone care can improve quality of life in these patients. Our aim was to determine frequency and care provided by Supportive Care Center Telephone Program (SCCTP) in advanced cancer patients. Methods: 400 consecutive patients who utilized palliative care service, 200 from outpatient Supportive Care Center (SCC) and 200 from inpatient Palliative Care (IPC), were followed for 6 months starting 3/2012 to examine call frequency and reason and outcomes including pain and other symptoms [Edmonton Symptom Assessment Scale (ESAS) and Memorial Delirium Assessment Scale (MDAS)] associated with utilization of SCCTP. We also examined the effect of SCCTP interventions on pain, ESAS and counseling needs. Results: 375 patients were evaluable. Median age 59 years, 53% female, 70% white. Most frequent cancer type were gastrointestinal (20%, p < 0.0001) for IPC and thoracic (23%, p <0.0001) for SCC. SCC patients had higher prevalence of CAGE positivity (28% SCC vs 11% IPC, p <0.0001), ESAS SDS(p=0.0134), depression(p=0.0009), anxiety(p=0.0097) and sleep(p=0.0015); MDAS scores were significantly higher in IPC (p<0.0001).115/400 patients (29%) utilized SCCTP. 96/115 outpatients (83%) used the SCCTP vs 19/115 IPC (17%). Common reasons for calls were pain (24%), pain medication refills (24%) and counseling (12%). Of 115 phone calls, 340 recommendations were made; 43% (145/340) were regarding care at home; 56% of these recommendations were regarding opioids. Patients who utilized SCCTP had worse pain(p=0.0059), fatigue(p=0.0448), depression(p=0.0410), FWB(p=0.0149) and better MDAS scores(p=0.0138) compared to non-utilizers. Conclusions: There was more frequent SCCTP use by outpatients than inpatients. Most common reason for utilization was pain control. Frequently, recommendations were made to continue symptom management at home. Patients who utilized SCCTP had worse pain, fatigue, depression, well-being scores and better delirium scores.
