4 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 Putting the Pieces together for Research

6 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’?
