Ambulatory case mix funding systems in Canada.

The implementation of inpatient case mix funding in Alberta and Ontario does not allow for adequate incentives to shift resources to an outpatient basis, where appropriate, or to provide outpatient care efficiently. This paper explores the prospects and problems of further extending case mix tools into this area. The availability of tools to characterize output for day surgery, special clinics and emergency care is surveyed. We conclude that case mix funding is desirable and feasible for ambulatory surgery; however, it is questionable for emergency care and special clinics. However, developments in this area in the United States will continue, and this will likely maintain an interest in Canada.
