Abstract
Diagnostic investigation process of healthcare is complex, medical practitioners’ goal is to find methods of standardizing their diagnostic investigation processes to reduce the time and cost and optimize the quality of healthcare. The technique that can be applied to mine valuable and useful knowledge of diagnostic investigation process of their interest from stored data is process mining. Process does not consider dynamic and causal dependencies in processes. This characteristic of process mining can be effectively applied in diagnostic investigation. This technique becomes more helpful and valuable where some treatment failed to provide favouring evidence. We used process mining in this paper to mine efficient diagnostic investigation process flow for hepatitis patients. There are several advantages of using process mining approach which can boost the effectiveness diagnostic investigation processes.
