Unfortunately, modern medicine, unfortunately, is not without errors. Therefore there exists a probability of unpredictable complications, establishment of an incorrect diagnosis, and in consequence and improper treatment. When dealing with various medical problems (collecting information about the patient, diagnosis, choice of solution tactics), the doctor faces the problem of decision - making. At the same time, the requirements for the accuracy of the diagnosis and its reliability are constantly increasing. The scientific approach is the main tool in the process of finding the truth, and, consequently, in the decision making process.
According to the modern model of clinical decision making, the competence of the physician is determined by knowledge of the mechanisms of diseases and clinical experience, the ability to evaluate and use scientific information in practice. Clinical laboratory diagnostics is a special industry of providing medical services. The results of the laboratory examination of the patient are based on about 80 % of the information of the necessary clinician to confirm or establish a diagnosis. The strategy for the development of clinical laboratory diagnosis should be subordinated to the general concept of health care development and its diagnostic doctrine. It is about the consistent structuring of high - tech production, which includes clinically and economically sound actions with appropriate organizational solutions, staffing and material equipment, and unified documentation. Management decisions in medicine can have a significant impact on both the overall financial health of a medical institution, the results of the indicators of the treatment prophylaxis, and the lives of many people who work there and receive assistance. Management work is necessarily linked to decision-making, because it is the choice of a particular action from the set of possible options. The need for decision-making is the responsibility of the management of the organization management, from the formulation of goals and to their achievement.
