Ambulatory Cancer Electronic Medical Record Extraction Standard

The Ambulatory Cancer EMR extraction standard (Cancer aEMR Extract) documents the requirements for submitting Activity Level Reporting (ALR) data.

ALR is the basic set of data elements required to produce the quality, cost and performance indicators for the Ontario cancer system, namely patient level activity focused on radiation, systemic therapy (chemotherapy) services and outpatient oncology clinic visits.

This standard will help to provide future guidance to hospitals and CCO with activity level reporting by improving data quality and reducing submission timelines and inefficiencies. It addresses challenges ranging from collecting and  reporting data from multiple sources to submitting data to CCO in various formats.


The Cancer aEMR Extract standard supports the transmission of  ALR data derived from patient-level records  within the cancer system that pertain to  radiation treatment, systemic therapy (chemotherapy) services and outpatient oncology clinic visits.


This standard is based on existing reporting, business, and technical requirements from eHealth Ontario’s clinical document specification. The standard is being validated through formal review with numerous Ontario stakeholder groups from April through September 2013.
