Readiness of clinical laboratory diagnostics and cardiologists to implement the recommendations of the fourth universal definition of myocardial infarction.

This study describes the problems of the implementation of the fourth universal definition of myocardial infarction in the medical institutions of four cities: Volgograd (with Volzhsky), Yekaterinburg, Perm, Ufa, and districts of the Volgograd region. The multicenter study was conducted in the form of a questionnaire of specialists in cardiology and laboratory services. After a survey of cardiac specialists, it was found that a third of them did not see the benefits of the hs-cTn test recommended for the diagnosis of myocardial infarction, and almost half of the specialists surveyed believed that myoglobin was a necessary test for detecting myocardial infarction. Probably, this is due to the fact that 16 clinical diagnostic laboratories from the 5 above regions still perform the determination of myoglobin in patients with suspected myocardial infarction. The material and technical support of medical and diagnostic institutions generally meets the requirements of the fourth universal definition of myocardial infarction. However, there is a problem of «qualitative¼ equipment of the regions of the Volgograd region, since only 3 out of 31 districts declared the possibility of carrying out a quantitative determination of hs-cTn , and qualitative analysis was carried out on platforms that are not monitored by the IFCC. It is worrying that almost half of the specialists of the clinical and diagnostic laboratories of the central district hospitals of the Volgograd region did not indicate the manufacturer of reagents for determining troponins. Thus, in the educational programs of advanced training of specialists in cardiology and laboratory services, it is necessary to include aspects related to the explanation of analytical characteristics, the characteristics of the technology for performing troponin tests and the related interpretation options for the results.

[The algorithms of evaluation of economic effectiveness of laboratory technologies].

The article considers several practical situations requiring estimation of economic effectiveness. The protocols of estimation, costs and effectiveness accounting requirements of practical public health are proposed. The necessity of development of correct epidemiological model is demonstrated to estimate profit of innovations of diagnostic stage. The estimation "costs-effectiveness" is made for troponins at diagnostic of cardiac infarction and prostate-specific antigen under screening of prostate cancer.
