Use of clinical pathways to identify patients with cancer who may benefit from serious illness conversations.

Abstract

12027 Background: Treatment pathways are widely used to provide decision support and encourage guideline adherence. Pathways data may be used to identify patients for targeted interventions to improve cancer care. For example, pathways data may enable the identification of patients with poor prognoses for whom serious illness conversations (SICs) should be prioritized to ensure goal-concordant care. Methods: For patients starting new therapies at Dana-Farber, oncologists select a node in clinical pathways to indicate the line of treatment. Subspecialty oncologists identified “poor prognosis” nodes in pathways, defined as therapies for patients with expected survivals of < 12 months and for whom an SIC would be appropriate (e.g., 3rd-line treatment for metastatic colon cancer). Pathway node navigations for patients with metastatic solid tumor malignancies with poor prognosis nodes (n = 21 disease pathways) were combined with electronic medical record data to identify SIC documentation in an advance care planning module within 6 months of pathway navigation and patients’ dates of death if present. For each node, we calculated the median overall survival (OS), the proportion of patients with an SIC, and the proportion of patients who died before reaching the next node. Results: There were 10,132 navigations for 7,031 patients (median age 67 years, 52% female, 86% White) between 8/16/2019 and 1/4/2023. With each treatment line, patients’ median OS decreased and SIC rates increased (examples for 3 diseases in Table). Among patients who reached poor prognosis nodes, the median OS was 4.9 months, mean SIC rate was 43.8%, and 60.2% of patients died without reaching a subsequent node. For nodes immediately prior to poor prognosis nodes, the median OS was 7.1 months, the mean SIC rate was 25.2%, and 31.3% of patients died without reaching the next node. 46.3% of patients died without reaching a poor prognosis node. The proportion of patients having an SIC at death was 40.9% among all decedents, 50.8% for decedents reaching a poor prognosis node, and 29.3% for decedents who do not reach a poor prognosis node. Conclusions: Clinical pathways can be used as a scalable method to identify patients with metastatic solid tumors and poor prognoses. In our study, only half of patients who reached a poor prognosis node had an SIC before death and nearly half of decedents never reached a poor prognosis node, underscoring the importance of identifying this population to improve end-of-life care. A clinical trial using pathways to identify and deliver interventions to increase SICs is ongoing. [Table: see text]
