So, what are the differences between the LIVE form downloads and “Research datasets”?Live Form Downloads•Real Time•Live Data•Each form is independent•Exact data entered
Site (SAS) Research datasets•Quarterly•Analytical ‘ready’ data
• Links all forms into 4 research datasets• Contains derived intervals and indicators • Integrity checks • Built-in ‘30 day’ data entry allowance• Recodes (e.g. ‘Other’ text boxes reviewed)• Completed/Validated forms

1 record per “patient” (contains demographics, primary implant information, overall outcomes)
1 record per “implant operation” per patient (contains demographics, ALL implant information, outcomes for a single implant)
1 record per “follow-up visit” per implant operation per patient(contains follow-up visit information, e.g. labs, hemodynamics, etc)
1 record per “adverse event” per implant operation per patient(contains adverse event information, e.g. date of occurrence, information based on Intermacs AE definition)
What is contained in a ‘research dataset’?
Quarterly Site (SAS) Datasets “Research Datasets”
Examples of statistical analyses that can be performed with your site’s SAS research datasets
• Overall survival• Survival by Device type • Time to First DLI by era• Risk Factor analyses: Death Model
