[Optimizing the prophylaxis of hospital-acquired deep vein thrombosis and pulmonary thromboembolism]. / Optimizatsiya profilaktiki vnutrigospital'nykh trombozov glubokikh ven i tromboembolii legochnoi arterii.

AIM: To reduce the number of preventable hospital-acquired venous thromboembolic events (HA-VTE) and to improve the quality of VTE prophylaxis at multiprofile hospital. MATERIAL AND METHODS: A comprehensive approach to preventing HA-VTE was developed, which involved the global trigger tool method to assess adverse events, as well as the computerized clinical decision support system (CDSS) to prevent HA-VTE on the basis of relevant clinical practice guidelines, and HA-VTE registry. RESULTS: A total of 50 patients (15 men, 35 women; their median age was 70.5 years) with HA-VTE were included in the HA-VTE registry in January 2014 to June 2015. Assessment of a trend in the prevalence of HA-VTE when introducing CDSS to prevent VTE showed its statistically significant decline in the total number of HA-VTE cases (χ2=7.325, df=1; p=0.0068) and in that of HA-VTE in surgical patients (χ2=7.266, df=1; p=0.0070). The statistical significance of χ2 for linear trend was not achieved for medical patients, which is probably due to the small sample size (χ2=2.764, df=1; p=0.0964). While introducing CDSS, there was a statistically significant reduction in the incidence of postoperative VTE from 8.76 to 4.17 cases per 1000 interventions (χ2=5.347, df=1; p=0.0208; the absolute values of HA-VTE and surgical interventions were used for the calculation). CONCLUSION: The proposed comprehensive approach can substantially increase the detection rate of HA-VTE and decrease its incidence rates. This requires a personified assessment of the risk of VTE and hemorrhage in all hospitalized patients on day 1 of their admission, timely initiation of recommended VTE prophylaxis, and dynamic assessment of the risk of VTE and hemorrhage for timely correction of the prophylaxis.

[Polypragmasy: A clinical pharmacologist's view]. / Polipragmaziya: vzglyad klinicheskogo farmakologa.

In the modern world, there is a rapid advance in the design and clinical introduction of a huge number of drugs that are able to cure a patient or to improve his/her health status on the one hand and to cause significant harm to his/her health on the other. Polypragmasy is the desire to enhance the efficiency of treatment and to help the patient recover from all developed diseases inevitably leads to the use of a large number of medications. At the present time, polypragmasy as a result of iatrogenia is a serious public health problem, as it is clinically manifested by a reduction in the effectiveness of pharmacotherapy, by the development of severe adverse drug reactions, and by a considerable increase in healthcare expenditures. The reason for the simultaneous prescription of multiple drugs may be comorbidity (multimorbidity), the availability of drugs, as well as clinical guidelines, manuals of professional medical associations, treatment standards that contain recommendations for using combination therapy with more than 5 drugs for only one disease in some cases, the efficiency of which corresponds to a high level of evidence. Currently, the fight against polypragmasy is one of the important tasks in rendering medical care to elderly and senile patients since it is a major risk factor of adverse drug reactions in this category of people. To minimize polypragmasy in elderly patients, it is necessary to use current methods for analyzing each prescription of a drug (the index of rational drug prescribing; an anticholinergic burden scale) and those for optimizing pharmacotherapy with the use of restrictive lists (Beers criteria, STOPP/START criteria) that will be able to reduce the number of errors in the administration of drugs and to maximize the efficiency and safety of pharmacotherapy.
