CCHIT and IHE Interaction CCHIT looks to IHE to provide specifications for EHR interoperability and functionality. Current In-Patient Certification Specifications for cardiovascular medicine are in process. CCHIT needs specification assistance from IHE in areas like: Variable Definition Image Access Summary Data Reports

Variable Definition As increasing demand for data from registries and government grow, data points take on different meaning. Seemingly like data points have different definitions, some intentional and some not intentional, which causes misunderstanding in cardiology service line areas.

Variable Definition Problem Statement What is the right definition? No place to check No independent coordinating body Continual “Reinventing the Wheel” Variable Type Free Text Field Size Yes/No coding Abbreviations Inaccurate field analysis Difficult to use variables in reports - need to create summary variables  programming Complexity Unintentional Definition variance “Many” meds for one med Varying techniques for maintenance

Image Access Image technology has made great strides in providing ability to view images at proprietary workstations and the demand that faces cardiologists is moving those images from proprietary systems to various communities in a timely and accurate fashion. Some video images of procedures are very large, occupying 4gb of information or even larger. The problem that is faced is how to get the information from the source in a usable manner.

Summary Data Reports There is a need to access summary patient information form various communities. Content is subject to vendors discretion, but format of the file should follow a standard like HL7 or XML. What is needed is the format specification and then the recommended way to display whatever was sent, including possibility of a device like an IPhone or Smartphone.
