Quantification of factors influencing differences in the Case Mix Index and their significance for health systems sustainability.

Case Mix Index (CMI) represents a standard indicator of hospital disease seriousness at both the national and international level. CMI is structured to compute hospital payments and not to follow up disease seriousness. It is considerably related to the data accuracy as well as patients’ medical records. The main aim of the study was to quantify the factors influencing the differences in CMI depending on the types of healthcare facilities, their geographical location, as well as the procedural aspects within the Slovak healthcare system. We use data published by the Institute for Economic and Social Reforms, which continuously surveys the quality and outputs of healthcare provided in the Slovak Republic. The data comes from multiple datasets that are issued by healthcare authorities and stakeholders is the Slovak Republic such as insurance companies, the Ministry of Health of the Slovak Republic, the Ministry of Finance of the Slovak Republic, healthcare facilities, the National Health Information Centre etc. Regression analysis indicates that the positive impact on the Case Mix Index is possessed by the Operating experience of doctors and Overall inpatients satisfaction; whilst the negative impact on Case Mix Index values is documented for variables Total rehospitalisation within 30 d, Intensive care unit mortality, Economy, and Transparency.
