Utilization of palliative care services in patients who died from stage IV non-small cell lung cancer (NSCLC): A retrospective study from a tertiary care center in rural Maine.

Abstract

95 Background: It is known that palliative care involvement in metastatic NSCLC cancer patients has been shown to improve quality of life in previous studies. The aim of our study was to analyze the utilization of palliative care services among patients who died from NSCLC and the setting in which these patients first received palliative care. Methods: This is a retrospective chart review analysis of patients with stage IV NSCLC who were diagnosed at Eastern Maine Medical center and the affiliated cancer center who died between January 2016 and December 2018. We collected demographic data, date and stage of diagnosis, location of palliative referral, location of first palliative care contact with the patient, time between diagnosis and death, utilization of hospice services and time between the initial palliative care consult and death. Results: 255 patients with stage IV NSCLC died between 2016 and 2018. Mean age was 65.5 years. Women were 49% and men were 51%. Majority (60%) of patients had good performance status with ECOG score between 0-1 at presentation. All 255 patients were referred to palliative care. The location of initial palliative care referral following diagnosis was 40% from the hospital, 32% from the oncology clinic and 28% from the outpatient specialist or PCP office. Overall, 174 patients (68%) were seen by palliative care and 81 (32%) were not seen. Of the patients seen 119 (68%) had their initial palliative evaluation in the hospital, and 55 (32%) in the clinic. Majority (55%) had more than one follow-up visit. Consults initiated in the inpatient setting were more likely to be seen by palliative care than in the outpatient setting (p 0.0009). Time between diagnosis to palliative care consult was less than one month in 39%, 1-2 months in 25%, 2-6 months in 21%, and more than 6 months in 14% patients. Patients seen by palliative care had a more likelihood to end up on hospice (p 0.09). The majority of patients seen by palliative care (53%) died within a month of initial consultation. Conclusions: All patients in our study population were referred to palliative care with 100% provider compliance. Among these, 68% were seen by palliative care. Interestingly, inpatient referrals were more likely to be seen by palliative care than the outpatient referrals. We think this is likely related to ease of access to palliative care team in the hospital as well as some of the patients being at terminal stages of their disease. About 33% of patients died within a month of their initial diagnosis, likely giving palliative care team a shorter window of opportunity to be seen in the outpatient setting. Prioritizing referrals of stage IV NSCLC patients might decrease the wait time after initial referral and increase the availability of palliative care services to these patients.
