  1. Physicians meeting the inclusion criteria at each step
  2. Family physician: All physicians with recorded specialty in the ICES Physician Database (IPDB) other than General Practice, Community Medicine, or Family Practice with Emergency Medicine are excluded
  3. Providing comprehensive care: To limit the dataset to general practitioners, we excluded individuals whose billing pattern showed a specialized practice. We evaluated 21 comprehensiveness primary care fee schedule codes, and required that the physician had billed at least 8 of these codes over the past 2 years
  4. Caring for at least 100 patients: We also excluded physicians to whom fewer than 100 patients could be attributed as these were likely to new graduates having not yet established their practice. The Ontario Ministry of Health and Long Term Care provides new graduates a fixed income during 48 months to allow them to establish their practice without financial hardship. These physicians are therefore not required to bill their encounters and could therefore not be assessed. Three IDOCC participants fell into that category
