Critical care nursing is an area of policy concern with respect to staffing projections, skill mix and educational preparation in both Canada and Australia. Despite many similarities between the health systems of these two countries, differences exist in both undergraduate and graduate specialty nursing education. In Australia, specialist education is primarily delivered via the tertiary sector as a formalised qualification, whereas the current Canadian model displays significant variation in duration, content, and mode of delivery. This paper provides a comparative perspective on the educational preparation of critical care nurses in these two countries. Consideration of alternative models of specialty nursing education may provide a method to improve recruitment and retention of staff while maintaining quality of care.
