Using cancer registry records linked with health insurance records to measure costs and services at end-of-life.
186 Background: Studies suggest that end-of-life (EOL) care for persons with cancer in the United States is variable and often misaligned with patient and family preferences. To better understand these issues, we developed reports on high-priority quality indicators and costs at EOL. Methods: Surveillance, Epidemiology, and End Results (SEER) records for solid tumor patients diagnosed with cancer in Western Washington state between 1/1/2007 and 12/31/2015 were linked with enrollment and claims from two regional commercial insurers. Using claims, we then developed algorithms to characterize EOL care for breast, colorectal, and non-small cell lung cancer (NSCLC), including costs of care at 90- and 30-days prior to death. Costs include all claims paid for ED, hospital, outpatient, and pharmacy care. We estimated patient out-of-pocket costs as the difference between allowed and paid claim amounts. Results: See Table. Across the largest 10 clinics in the region there was considerable variability in the average costs of cancer care in the last 90 days of life. The clinic-specific average ranged from $24,532 to $72,931 for breast cancer, $30,495 to $65,975 for colorectal cancer and $23,320 to $59,641 for NSCLC. Conclusions: At the end of life, care for patients with advanced breast, lung, and colorectal cancer is highly variable, costly to patients, and may be misaligned with the goals and preferences for patients and their family members. While the results may reflect both appropriate and unnecessary care, the large variation across clinics suggests opportunities for improvement. Further research is needed to identify factors associated with use of low-value, high-cost services at the end of life. [Table: see text]
