Various methods of quality improvement and performance assessment have been developed in the discipline of industrial and management engineering. The purpose of this thesis is to examine the feasibility of some of these methodologies in the medical arena. It claims that medical treatment is a process, and as such can be improved by methods used in non-medical organizations where outcome is a quality indicator of the process. It examines whether the implementation and use of components from quality methodologies in the medical arena does indeed improve clinical performance and outcome.

The results showed that there was a significant improvement in both areas. They also showed a relationship between performance and clinical outcome. Thus the study

provides a well documented example of the advantages of the use of quality methodologies for the improvement of clinical performance and outcome. Despite the fact that these methodologies were written for business organizations, which are considered to be relatively simple and controlled, this thesis shows that these methodologies can also be applied to an organization as large and complex as a hospital. It is worth noting that the use of these methodologies for the improvement of clinical practices, performance and outcome is not merely a one-off project, but a basic conceptual change in the way an organization can be run in the future. The employment of such methodologies demands persistent efforts over a long period of time.
