Lessons learned from the Canadian cancer registry experience.

Health leaders and caregivers are focused on evidence-based data to drive care delivery and practice. Ensuring the health system is functioning effectively and efficiently and that patient outcomes are reaching expected targets are topics that permeate conversations at the local, provincial, and national levels. However, as many leaders have come to understand in recent years, healthcare data collection and producing meaningful, high-quality metrics is a complex set of tasks, requiring its own level of attention and dedicated resources. In the healthcare data realm, there are opportunities to learn from experience. One of these opportunities is the population-based cancer registry, which is one of the oldest examples of standardized data collection in the Canadian health system.
