Предпосылки: у кошек сложно оценить тяжесть зуда, так как дискомфорт у них проявляется усиленным вылизыванием и (или) расчесыванием. Гипотеза/цели: нашей целью была разработка и проверка достоверности шкалы оценки зуда специально для кошек (VAScat). Методы: шкала была разработана как двойная визуальная аналоговая шкала (ВАШ), одна для оценки вылизывания и вторая — расчесывания, с ключевыми словами для описания тяжести проявлений и поведения. Зуд у каждой кошки оценивали по высочайшему баллу (ВАШ-макс.) по любой из ВАШ. Владельцы 153 кошек с кожными заболеваниями и 108 здоровых кошек оценивали зуд у своих кошек с помощью шкалы VAScat. 96 из 153 кошек с кожными заболеваниями также оценивали повторно через 4–8 недель лечения. Результаты: коэффициент корреляции Пирсона между оценками по ВАШ вылизывания и ВАШ зуда составил r = 0,26 (p < 0,01), а значение альфа Кронбаха ‒ 0,41. Оба индекса показали, что две шкалы измеряют разные проявления зуда и поддерживают использование двойной системы оценки. Сравнение с числовой шкалой тяжести зуда (0, отсутствует; 1, легкий; 2, умеренный; 3, сильный) дает основания полагать, что ВАШ вылизывания и ВАШ расчесывания по отдельности не подходят для измерения зуда от отсутствующего до легкого (степени 0…1), тогда как ВАШ-макс. ‒ подходит (p = 0,001). Все шкалы — ВАШ вылизывания, ВАШ расчесывания и ВАШ-макс. ‒ подходили для оценки более высоких степеней зуда (2///3, p < 0,01). Шкала VAScat позволяла измерить снижение зуда после лечения, так как оценки после лечения значительно снизились по сравнению с оценками до лечения (p < 0,0001). Выводы и клиническая значимость: шкала VAScat показала себя полезным инструментом для оценки зуда у кошек и наблюдения за ответом на лечение зуда.

Background: Assessment of the severity of pruritus is difficult in cats, because they manifest discomfort by increased licking, increased scratching or both. Hypothesis/Objectives: Our objective was to develop and validate a feline specific pruritus scale (VAScat). Methods: The scale was designed as a double Visual Analog Scale (VAS), one VAS for licking and one for scratching, with severity and behavioural descriptors. The highest score (VAS-max) on either VAS was taken as the pruritus score for each cat. Owners of 153 cats with skin diseases and of 108 healthy cats scored their pet's pruritus using the VAScat. Ninety-six of 153 cats with skin diseases also were re-evaluated after four to eight weeks of treatment. Results: Pearson's correlation value between VAS-licking and VAS-scratching scores was r =0.26 (p <0.01), and Cronbach's alpha was 0.41. Both indexes indicated that the two scales measure different manifestations of pruritus and supported the use of a dual assessing system. Comparison with a numerical pruritus severity scale (0, absent; 1, mild; 2, moderate; 3, severe) suggested that VAS-licking and VAS-scratching scales taken alone are unsuitable for measuring absent to mild pruritus (grades 0…1), while VAS-max is (p =0.001). VAS-licking, VAS-scratching and VAS-max all were suitable to assess higher levels of pruritus (grades 2…3, p <0.01). The VAScat was able to measure pruritus improvement following therapy, as post-treatment scores were significantly decreased compared to pre-treatment ones (p <0.0001). Conclusions and clinical importance: The VAScat proved to be a useful tool to assess pruritus in cats and for monitoring the response to treatment for pruritus.
