Harmonization of critical values across the GTA hospitals
Critical values aid in the interpretation of patient test results.
Harmonization of critical values used by hospitals and their associated clinical laboratories across the GTA is essential to ensure consistency in the definition and identification of 'critcal state' patients.
To assess the feasibility for harmonization of critical values across GTA, we are surveying Laboratory Medicine departments of hospitals in areas of:
Current available guidelines
This guideline provides current best practice recommendations for developing and implementing a policy and procedures for the identification, reporting, and management of critical- and significant-risk laboratory results.
It emphasises management responsibilities such as development of the policy, the process, procedures, job descriptions, and monitoring systems that ensure effective reporting and compliance with regulatory requirements.
