Рандомизированное открытое сравнение среднего времени нахождения международного нормализованного отношения (МНО) в терапевтическом диапазоне при использовании двух подходов к начальному дозированию варфарина в период госпитализации: стандартного и с применением индивидуальных показателей больных (клинического алгоритма). Материалы и методы. В качестве изучаемого подхода к дозированию варфарина использовалась методика, учитывающая клинические особенности больных. В группу изучаемого подхода (группу вмешательства) рандомизирован 31 человек, в группу с использованием стандартного подхода (группу контроля) - 29 человек с различными показаниями к лечению антагонистом витамина К. Целевой диапазон МНО для всех больных составлял от 2,0 до 3,0. Результаты. Среднее время нахождения значений МНО в терапевтическом диапазоне (Time in Theraupeutical Range - TTR) и доли целевых значений МНО в течение всего времени подбора дозы препарата оказались небольшими. TTR составило 22,4% при использовании стандартной методики и 21,4% при применении клинического алгоритма, что значительно ниже желаемых 60%. Заключение. Возможности по достижению целевого МНО независимо от режима дозирования варфарина в условиях стационара очень ограничены.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To perform a randomized, open-label comparison of average time in therapeutic range (TTR) of international normalized ratio (INR) using two approaches to initial warfarin dosing during hospitalization: the standard method and the one using individual patient characteristics (clinical algorithm - the studied approach). Materials and methods. We randomly assigned 60 patients with different indications for vitamin K antagonist therapy to the studied approach (n=31, intervention group) or to the standard method (n=29, control group). А target INR range for all patients was 2.0 to 3.0. Results. The average TTR and portions of INR values within target range during the whole time of drug dosing turned out to be small. TTR was 22.4% with standard method and 21.4% with clinical algorithm, which was well below desired 60%. Conclusion. The opportunities for achieving target INR in inpatient settings, regardless of warfarin dosing regimen, are limited.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>варфарин</kwd><kwd>подбор дозы варфарина</kwd><kwd>международное нормализованное отношение (МНО)</kwd><kwd>стабильное МНО</kwd><kwd>время нахождения значений МНО в терапевтическом диапазоне (Time in Theraupeutical Range - TTR)</kwd><kwd>шкала SAMe-TT2R2</kwd><kwd>warfarin</kwd><kwd>warfarin dosing</kwd><kwd>international normalized ratio (INR)</kwd><kwd>stable INR</kwd><kwd>time in therapeutic range (TTR)</kwd><kwd>SAMe-TT2R2 score</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kimmel S.
