This thesis address one of the most important topics for the human being; health. Specifically, the research is about the deficiencies of the health system in Mexico. This paper shows the importance, how the system works and its current situation in the country. The purpose of this research is, based on the Pareto principle (20% vs 80%), to find how to solve most problems with the least possible investment.   It was found that the common denominator in the problems was the process and flow of information of the patients; specifically, the health records. The researchers address the issue at first explaining in a deep way the health records to highlight their importance in the health care system. In order to corroborate this finding in the literature; The researchers designed an interview, which was applied to physicians from the two main health institutions in Mexico in order to collect the necessary information to develop the thesis.   Since the design of the research is qualitative; the necessary social context is given to be able to understand the analysis and the results; likewise, the authors explain in detail the methodology used.   In spite of other important factors that were found such as the lack of results despite the investment and deficiencies in the infrastructure; It was concluded that, in fact, most of the problems were derived from the problems of health records. These results are important because it gives a parameter of what must be corrected first in order to have the expected results and a better health system.
