Briesacher and colleagues highlight that we identified a greater reduction in mean out-of-pocket expenditures (32%) among Medicare beneficiaries participating in the MEPS1 than previous studies (range, 13%-18%).2- 3 They suggest that this may be partly owing to the longitudinal study design used, which limits the generalizability of our findings to the elderly Medicare population.
