2 Research Goal Compare/evaluate primary care quality indicators for five models of primary care delivery in Winnipeg Describe the impact of patient social complexity on primary care quality indicators and primary care provider panel size 2 Manitoba Centre for Health Policy

3 Methods Study period: April 1, 2010 to March 31, 2013 Describe and compare patients, primary care providers, and each model of primary care delivery 29 primary care quality indicators 3 Manitoba Centre for Health Policy

A blank cell represents no significant difference between the two models of primary care. *Full Adjusted Rate/Odds Ratio/Index: Adjusted for patient income quintile, sex, age, and RUB; and provider age, sex, years of practice, country of graduation (Canada or other); and social complexities.

15 Limitations Administrative data lacks depth Limited to physician/nurse practitioner visit data No formal rostering The income data presented is ecological vs person level social complexities 15 Manitoba Centre for Health Policy

16 Conclusions The demographic of patients vary across different models of care No model of care does better than the others across all categories of indicators Room for improvement across all models of care 16 Manitoba Centre for Health Policy
