OLIS Deployment

OLIS Deployment

What is Ontario Laboratories Information System (OLIS) Deployment?

The Ontario Laboratories Information System (OLIS) gives authorized health care providers access to lab test orders and results from hospitals, community labs and public health labs. As patients move between hospitals, family physicians, home care and long-term care settings, OLIS makes viewing patients'current and past test results easier and enables treatment decisions to be made at the point-of-care. Clinicians using an OntarioMD-certified electronic medical record (EMR) can access the latest lab results for their patients in OLIS or perform patient queries.

OLIS Deployment is a service provided by OntarioMD on behalf of Ontario Health to connect community-based family physicians, specialists and nurse practitioners using a certified EMR to OLIS.

A note on patient consent to access lab results through OLIS: Patient lab results provided through OLIS are considered Personal Health Information. A Health Information Custodian (HIC) can rely on implied consent to access these results when they are part of the patient's circle of care for the purposes of providing health care to the individual. A patient has the right, in some circumstances, to restrict/block access to their results. This may restrict the lab results you see. For more information, please visit the Information and Privacy Commissioner of Ontario website
