The effective management of this disease directly depends on the timely prescription and escalation of treatment with medications altering course of multiple sclerosis. The key factor in optimizing medical care is organization of specialized structures. The specialized Multiple Sclerosis Clinic was opened in the Komi Republic in the beginning of 2021. The purpose of the study is to assess dynamics of key indicators of medication therapy of multiple sclerosis during 2018–2024 and to determine impact of opening of Multiple Sclerosis Clinic on these indicators using methods of statistical analysis.</abstract><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>treatment</kwd><kwd>medications altering course of multiple sclerosis</kwd><kwd>treatment dynamics</kwd><kwd>second-line therapy</kwd><kwd>high-efficacy medication</kwd><kwd>organization of medical care</kwd><kwd>Multiple Sclerosis Clinic</kwd><kwd>statistical analysis</kwd><kwd>χ² criterion</kwd><kwd>regression analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>динамика лечения</kwd><kwd>препараты, изменяющие течение рассеянного склероза</kwd><kwd>терапия второй линии</kwd><kwd>высокоэффективные препараты</kwd><kwd>организация медицинской помощи</kwd><kwd>Кабинет рассеянного склероза, статистический анализ</kwd><kwd>критерий χ²</kwd><kwd>регрессионный анализ</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Сороковикова Т.
