CCHD Screening

Newborn Screening Ontario (NSO) is collaborating with Ontario hospitals and midwifery groups to implement screening for Critical Congenital Heart Disease (CCHD) for Ontario babies throughout 2017. CCHD refers to conditions where a baby’s heart or major blood vessels around the heart have not formed properly. They are called critical because they require surgery or intervention in the first year of life to ensure healthy outcomes for the baby.

Our goal is to support quality, consistency and access to CCHD screening for all babies in Ontario. Specifically, NSO is supporting the implementation of CCHD screening through the provision of equipment standards and education resources. We will also be collecting CCHD screening results  for quality assurance and program evaluation.

This section of our website includes information for hospitals and midwifery practice groups who have either implemented or are working towards implementation of CCHD screening. Here you will find screening protocols, resources, and important communications from NSO.
