Abstract: Public financial management reforms played an important role in the restructuring of social institutions and organizations. Researchers examined the effects of the reform according to their expertise. However, the research has focused on the results and the effects of the results rather than focusing on the starting point of the actions of the main actors who are the source of knowledge. In our research, first of all, the social life world of a public hospital was schematized. The hospital information management system (HIS) data, where the main actor actions are recorded at the starting point of the information source, was accessed and the accuracy of these data was analyzed with Benford’s Law, which can be considered as data mining. There are two databases (subsystems) in the public hospital where sales revenues are tracked. These are HIS and uniform accounting system (UAS). The information produced in HIS consists of unstructured data. By structuring this data with accounting information, HIS financial statement variables were created. Logit analysis, which is considered one of the machine learning techniques, was performed using the HIS financial statement variables and the existing UAS financial statement variables Beneish Model. It was found that there is a statistically significant difference between HIS financial statements and UAS financial statements. It is argued that this difference can be eliminated by using accounting language (accounting coding system).
