Comparative Effectiveness Research Public Use Data Pilot Project - Chronic Conditions

As part of the Comparative Effectiveness Research (CER) Public Use Data Pilot Project, IMPAQ completed the CMS 2008 Chronic Conditions Public Use File (PUF). This PUF is an aggregated file in which each record is a profile or cell defined by the characteristics of Medicare beneficiaries. A profile is defined by all combinations of age category, gender, various chronic conditions, and dual-eligibility status of the beneficiaries. For each profile many claim- related variables are provided in the form of averages.

A short summary of IMPAQ’s CER Public Use Data Pilot Project can be found here.

The file and accompanying documentation and data dictionary can be found on the CMS website.

Information on the Comparative Effectiveness Research Public Use Data Pilot Project - Inpatient Claims can be found here.  

The CMS 2008 Chronic Conditions PUF provides averages for various cost and/or utilization measures for the full Medicare population disaggregated by the profiles. The Dashboard below contains three sheets/tabs. The first tab provides aggregate descriptive statistics by Medicare program in which beneficiaries were enrolled, age category and gender. The second and third tabs present data on i) Part A payments and utilization for beneficiaries enrolled in Fee-for-Service (FFS) Part A for all 12 months of 2008, ii) Part B payments and utilization for beneficiaries enrolled in FFS Part B for all 12 months of 2008, and iii) Part D drug cost and events for beneficiaries enrolled in Part D for all 12 months of 2008 when all chronic conditions are available. The effect of each chronic condition or combinations of chronic conditions as well as the dual eligibility status on average Medicare payment amount and utilization measures per enrolled beneficiary can be analyzed by changing the appropriate indicator(s). For details of the variables in the PUF, source files, and disclosure limitation techniques used in the preparation refer to the documentation and data dictionary. The acronyms used in the Dashboard are provided at the end of the page.
