- In the fall of 2014, Health Quality Ontario released A Primary Care Performance Measurement Framework for Ontario. Recognizing the large number of recommended measures and the limited availability of data related to those measures, the Steering Committee for the Primary Care Performance Measurement (PCPM) initiative established a prioritization process to select two subsets of high-value performance measures - one at the system level and one at the practice level. This article describes the prioritization process and its results and outlines the initiatives that have been undertaken to date to implement the PCPM framework and to advance primary care performance measurement and reporting in Ontario. Establishing a framework for primary care measurement and prioritizing system- and practice-level measures are essential steps toward system improvement. Our experience suggests that the process of implementing a performance measurement system is inevitably non-linear and incremental.
