Diagnosis

In order to identify them and understand the cause of disturbances in the work of internal organs, it is necessary to analyze the state of the patient's systems, accompanying the process of diagnosing. Any such analysis has three main tasks:
• determine the current state of the patient's body systems (diagnose)
• determine the prognosis of the patient's condition for the future
• to develop a decision on therapeutic actions to improve the prognosis
However, already in the formulation of the diagnosis there is some inaccuracy. Using the assessment of clinical situation, morphological analysis, we always "late" because it does not put a deterministic (causal) and not predictive, and ascertaining the diagnosis. For example, a diagnosis of "cardiomyopathy" or "myocardial infarction" is just a statement of existing specific myocardial injury, ie, already a fait accompli - the investigation of the process. But in these diagnoses there is no indication of the cause of this effect. In fact, in most cases, the names of diagnoses are not the names of diseases, but the names of the results of diseases, the names of defects of various organs.
Ultrasound echolocation of internal organs, contrast and conventional radiography, radioisotope studies, computed tomography, spirometry, etc., allow to determine changes in the shape of the relevant organs, their dimensions, thickness and volume, ie, morphological (static, structural) parameters that characterize condition or type of affection of an organ. We can compare these parameters with due rest or load peak (minimum or maximum proper values) and evaluate them as equal, greater or less than they should. However, the form, thickness and volume are not functions of organs, but the result of the function of various systems of the body.
The concept of "function" includes functional (dynamic) parameters that characterize actions such as force, pressure, speed, etc. The dynamic concept of "function" is a working tool only for system analysis. The function of the body systems can be sufficient or insufficient, and it is possible to estimate this only if we compare the actual curves of these parameters with the proper curves. The notion of a "proper curve" differs from the notion of "due magnitude" in that the latter is a unit value, and the "proper curve" is a set of unit values ​​arranged in a curve. But the notion of "due curve" is almost unknown and not applicable.
The prognosis of the patient's condition can also be only probabilistic. We can know how much chance a patient has of being in a certain state after a certain time, but we can never know for sure what will happen to him. If, for example, a cancer patient is found in a patient in the lungs, it means that after 5 years from the onset of the disease, he has only 15-20% of the chances to stay alive, regardless of whether he will take any medication or not . At the same time, this particular patient can die within the next few days, but can also get spontaneously cured of cancer, since this, although very rarely, happens. Ie, the forecast varies from "the patient if does not die" to "that will live" with this or that degree of probability. This uncertainty is fundamental and not removable, since it arises on the basis of the probabilistic principle of statistical analysis, which is the main instrument of organo-morphological analysis.
If only the forecast was probabilistic, this could be reconciled. But the choice of the method of treatment is also probabilistic. For example, this type of treatment gives 80% of a favorable outcome. This means that the patient has a 20% chance of receiving the wrong treatment. And even if the attending physician tries to constantly monitor the patient's condition with the aim of making the necessary correction to the treatment regimen, even in this case he will always be late in assessing the medical situation because of the above reasons. The loss of time is fraught with the deterioration of the patient's condition, as the resources of his body are already reduced and, because of the illness, continue to decline.
