 Objectives: Improving the system and methods of collecting data related to the adherence level is one of the biggest problems not only in measuring the level of non – adherence, but also in assessing its impact on all participants in the health care system. An innovative approach to the application of existing methods using the information systems (IS) can in many ways help to increase the volume and reliability of data. Implementation (ICT) in Sarajevo Canton can be a pilot project in Bosnia and Herzegovina (BiH), or in Federation of Bosnia and Herzegovina (FBiH), as an opportunity to improve the methods of collecting data related to non-adherence level, by obtaining more precise and accurate information about the role and importance of adherence in the health system, without investing significant financial resources.  Methods: Comparison of the method of measuring the degree of adherence of the previous research results in the world and the practical application of the health system in the Sarajevo Canton.  Results: Applying modern information technologies (IT) and information systems (IS), together with the creation of a unique data collection methodology with a number of sources, obtained through various methods, it is possible to obtain data and information from much larger sample with different characteristics (economic, social , demographic, type of disease, therapy, etc.).  Conclusion: By improving data collection methods, it is possible to get accurate and precise data on the adherence level, or provide a better insight into the role and importance of adherence.
