Six Sigma methodology was used in a District General Hospital to assess the effect of the introduction of an educational programme to limit unnecessary admissions. The performance of the doctors involved in the programme was assessed. Ishikawa Fishbone and 5 S's were initially used and Pareto analysis of their findings was performed. The results were analysed and it was found that it was favouring the use of this technique, as the Six Sigma value increased from 2.6 to 4 producing a 99.4% yield. In conclusion this study stresses that The Six Sigma methodology is an acceptable tool which can be used for improvement of the performance of a Hospital Department and also of individuals; it can easily be used to improve the service safety and the patients' requirements.
