Few issues engage the attention of health policy and management stakeholders like the quality of care rendered to patients. And justifiably so; the ethical duties that attend the promotion of health in any society require attention to determine whether care provided to patients is successful and whether there are means to improve it given the social resources available (Liang, 2000b). As part of this effort, policy makers and providers have attempted to assess the process and outcomes of care to identify means by which care may be enhanced, and thus patient health advanced. Further, such efforts seek to utilise scarce societal resources more efficiently to increase the benefit associated with each allocation.
