eCHN is a pediatric EMR and HIE developed in 1999 by the province of Ontario, Canada and The Hospital for Sick Children of Toronto, Ontario. "eCHN was Canada's first integrated electronic health record solution and is currently the largest province-wide network of its kind in Canada." At launch, it served 5 hospital sites, today it serves 100 hospital sites and houses more than one million patient records. Principal developers include Andrew Szende and Brendan Gibney [2].

Clinical applications include [1]:

  • laboratory results and reports
  • admission, discharge and transfer data
  • clinic notes
  • radiology images and reports
  • consultants' letters
  • surgical notes
  • scanned documents
  • medication administration reports

The use of eCHN has been growing rapidly- from 1.5 million patients in 2009 to over 2.5 million patients in 2012, and from 10.5 million records of patient encounters in 2011 to nearly 15 million in 2013 [3].

New Applications and Services

  • In 2012, eCHN added a new service, e-Referral. This service is used by The Hospital for Sick Children to provide all of its referrals to its ambulatory clinics [3].
  • In 2014 a new tool, iSCREEN Tracker, was incorporated into the eCHN system. The iSCREEN tracker was developed in collaboration with the SickKids Diabetes Clinic, and provides all patient data required for monitoring and managing diabetes cases using a dashboard viewer [3].
