Strengths
- Financial data including: out-of-pocket costs as well as total costs

- Race/ethnicity of beneficiary is unknown
- Geographic information is limited to beneficiary state/region and MSA only
- Provider (physician and hospital) IDs are largely missing and anonymized
- Only in-hospital mortality is known for the earlier years of data – long term mortality is entirely unknown
