Welcome to the CEHR Net home page.  CEHR Net is pronounced "care net", and stands for Collaborative Electronic Health Record Network.

Purpose

The goal of CEHR Net is to produce re-useable Electronic Health Record (EHR) software components.  

An EHR is a longitudinal (ideally cradle-to-grave) collection of medical records for an individual.  Its main function is to provide clinicians with the information they need about their patients in order to make sound diagnosis and treatment decisions.  

Status

The CEHR Net initiative evolved from work in clinical systems integration that began at University Health Network in 2000.  

Our  initial goals were to develop a general strategy for integrating diverse operational systems, and to produce software components in support of this strategy.  The first version of a strategy document was released in February 2003.  Later that year, Canada Health Infoway produced a strongly overlapping strategy that achieves the goals in which we are interested.  Thus we are no longer developing a separate strategy, and are focused entirely on implementation.  

Products 

We have released the following products to date: 

• A demo system which has been live since 2002, integrating clinical data from University Health Network and Mount Sinai Hospital.  
• An HL7 engine, a library that is used by many other modules for interaction with HL7-compliant systems 

Other products in progress include: 

• PRO (patient results online), the next generation of the demo system above
• PLS (patient linking service), a system that tracks HL7 ADT messages from multiple sites and links identities that belong to the same person
• A secure audit trail component 
• A generic data access component that abstracts the reading and writing of simple records from various persistent stores, including SQL, LDAP, and XML files.
