Note The subsample consists of 2669 CanCORS patients who died within 15 months of diagnosis and had at least one hospice-use record from two sources. Outcome model: Equation (1.1), reporting model for medical records: Equation (1.2), and reporting model for Medicare claims: Equation (1.3). Posterior medians for β_O and β_R’s are based from 10⁵ iterations of the Gibbs chain. Estimates with 95% CIs (not shown) excluding 0 are highlighted with *. The reference categories are lung cancer, younger than 65 years old for the outcome model and reporting model for medical records/younger than 70 years old for the reporting model for Medicare claims, White, college, more than 60K, stage I. The variable ‘Days till death’ is included in the model using a standardized Z-score.
