By taking into account the fact that the percentage and category of a diagnosis discrepancy (DD) are used as one of the criteria of the health care quality control system, rather than used to set up a quality management system, it becomes more evident that we should agree to the proposal by Prof. I. A. Kazantseva that it is inexpedient to use DD categories, which simultaneously excludes them from the criteria for assessing the quality of health care delivered in the therapeutic-and-prophylactic institutions. For this, Appendix No. 7 to the 4 April, 1983 Order No. 375 "On further improvement of postmortem service in the country" in the part concerning the grouping of DD into categories should be officially recognized invalid. The pathologist's duty should be to state "coincidence" or "discrepancy" of diagnosis and the KILI, LKK, or KEK should elucidate reasons for DD as done at the Moscow Regional Research Clinical Institute, with the further reflection being given in the autopsy protocol.
