CMS Data in MESA April 2017

This presentation by Craig Johnson provides an overview of the current use and planned model for using CMS data in MESA. It includes information on CMS indication of missed events, as well as its use in analyzing MI, stroke, atrial fibrillation, and heart failure. The status of CMS renewal and the responsibilities of individual cohorts are also discussed.

Presentation Transcript

  1. CMS Data in MESA April 2017 Presented by Craig Johnson

  2. Outline • Status of renewal • Current use of CMS data in MESA • Planned/model for use of CMS data • CMS indication of missed events • MI • Stroke • Atrial Fibrillation • Heart Failure

  3. Status of CMS Renewal • CMS – NHLBI Agreement expiring • Individual cohorts will be responsible for obtaining CMS data (Duke is no longer supporting) • CMS fees now will be covered by MESA • DUA currently under review with RESDAC • 2015 data scheduled for Summer 2017

  4. Current Use of CMS Data • MESA CC has access to raw CMS data • Contains identifiers • Prohibited from sharing • Processed into deidentified analytic datasets

  5. Current Use of CMS Data • Investigators have access to processed data • Contains no identifiers • CMS enhanced analytic datasets • Upon request (to ensure compliance with CMS requirements, consistent use of events data, …) • Public Access datasets restricted • CC responsible for ensuring compliance • BioLINCC and dbGaP • MESA identified datasets only

  6. Planned Use of CMS Data • Provide data to FCs • CMS identified event • FCs investigate (same surveillance) • Abstraction and review • Fully adjudicated events incorporated into the analytic datasets • Specified in the DUA that we intend to treat all events the same (CMS identified same as MESA) • A common events dataset will be released • MESA Investigators, BioLINCC, dbGaP
