Eligibility Criteria
Inclusion
- Subjects will be either Medicare or Medicaid beneficiaries with available claims from 1999 to 2015. For projects requiring detailed medication information, inclusion will be limited to those with Part D claims from 2006 to 2015. Eligibility for each project will be based on claims for the appropriate disease (e.g. RA) or procedure (e.g. hip arthroplasty).
- Medicare beneficiaries will be excluded (or censored) if they do not have both Part A and Part B coverage, or enrolled in Medicare Advantage plans (Part C), as detailed claims for these beneficiaries are not available. We will also exclude dual-eligible (Medicare and Medicaid recipients) as these subjects have distinct clinical conditions (e.g. blindness) that distinguishes them from most Medicare beneficiaries. There will be no exclusions based on gender, race, ethnicity, or cognitive impairment.
