We investigated 70 patients from chronic departments who may have changes in the normal percentage of coagulation (neurology, surgery and orthopedics) within the Bacău County Emergency Hospital, during September-November 2021. Mainly, variations of values of APTT (partially activated thromboplastin time) and INR during Quick (International normalized ratio INR; international standardized procedure introduced by WHO). After the percentage distribution of patients according to the anticoagulant used in the treatment, there is a preference for combinations of classic anticoagulants with those of the new generation and a significant reduction in aspirin use which seems to have no therapeutic value as anticoagulant. The choice of a new generation anticoagulant in favor of another is not currently supported by evidence from any direct comparison study. Anticoagulants work differently and are therefore monitored by different laboratory tests. The doses in which it is administered are very varied.
