Evidence from the Dartmouth Atlas of Health Care researchers and others demonstrates substantial area-level variation in intensity of care and health care spending at the end of life across the [...], Objective. Assess validity of the retrospective Dartmouth hospital referral region (HRR) end-of-life spending measures by comparing with health care expenditures from diagnosis to death for prospectively identified advanced lung cancer patients. Data/Setting/Design. We calculated health care spending from diagnosis (2003-2005) to death or through 2011 for 885 patients aged >65 years with advanced lung cancer using Medicare claims. We assessed the association between Dartmouth HRR-level spending in the last 2 years of life and patient-level spending using linear regression with random HRR effects, adjusting for patient characteristics. Findings. For each $1 increase in the Dartmouth metric, spending for our cohort increased by $0.74 (p < .001). The Dartmouth spending variable explained 93.4 percent of the HRR-level variance in observed spending. Conclusions. HRR-level spending estimates for deceased patient cohorts reflect area-level care intensity for prospectively identified advanced lung cancer patients. Key Words. Variation, health care expenditures, lung cancer
