Title

A Cost Analysis of Skeletal Related Events Among Elderly Men with Stage IV Metastatic (M1) Prostate Cancer

Abstract Summary

We analyzed patients aged 66 years or older, diagnosed with incident stage IV (M1) prostate cancer between 2000 and 2007 from the linked SEER-Medicare dataset. A propensity score for the incidence of a SRE was estimated using a logistic regression model including demographic and clinical baseline variables. Patients with SREs (cases) were matched to patients without SREs (controls) based on the propensity score, date of diagnosis, last observation date and death. The SRE diagnosis date of a case was assigned as the index date of the matched control. The difference in costs between cases and controls (i.e. incremental costs) were calculated for the 12 month pre- and post-index periods. Difference-in-difference estimates were derived to represent the average pre-post incremental cost difference by type of SRE. The analysis was conducted from a US Medicare perspective.
