Turkish Adaptation of the VascuQoL-6 Quality of Life Scale

VascuQoL aims to assess quality of life in peripheral arterial disease, regardless of disease severity (i.e. in intermittent claudication and critical limb ischemia). It consists of 6 items. Each item has a 7-point response scale (1: worst quality of life; 7: best quality of life).

In Takayasu arteritis, the disease extent index (DEI.TAK) was developed in TAK as a criterion that focuses on findings related to large vessel disease rather than general characteristics of the disease. In 2010, the new version of DEI.TAK, the Indian Takayasu Clinical Activity Score-ITAS2010, was created. The 5 main items belonging to the cardiovascular (CV) system, Hypertension and Stroke, are scored as 2 points each. All other items (marked only as circles) are scored as 1 point each. In addition to the 2 points due to the presence of the first 5 items in the CV section, each murmur, claudication, loss of pulse or pulse inequality is scored as 1 point each, and the total score is determined by adding these 2 points. When calculating the acute phase response ITAS (ITAS.A), first the ITAS2010 is calculated and then the acute phase response values are scored as 1-3 points within certain intervals and added to the ITAS2010 score. The definition of active disease is > 1 point for ITAS2

It is one of the most frequently used scales to measure quality of life, consisting of 8 subcategories: physical functionality, social functionality, role limitations due to physical complaints, role limitations due to emotional problems, mental health, energy-vitality, pain, and general health perception. Separate scores are obtained for each subscale and the scores range from 0 to 100. A score of 100 indicates good health status, and a score of 0 indicates poor health status. Its Turkish validity was carried out by Koçyiğit et al. in 1999.

EQ-5D-3L consists of two parts: EQ-5D-3L descriptive system and EQ-5D-3L visual analog scale (EQ-5D-3L VAS). EQ-5D-3L descriptive system total score is between -0.59 and 1. "1" indicates the best health, while negative values indicate low quality of life. EQ-5D-3L VAS is scored between "0" and "100". (0: worst imaginable health status and 100: best imaginable health status)

This index aims to evaluate all types of involvement in Behçet's disease. BDCAF is filled out by the clinician and the evaluation is made considering the day the patient comes and the last 4 weeks. The evaluation of major organ involvements such as eye, gastrointestinal system and neurological involvement should be done by experts in their field. Active findings seen in the last 4 weeks in all systems are scored and a score between 0 and 12 is obtained.It has been stated that the BDCAF score must be 2 or above for the disease to be considered active.

Unlike BDCAF, it is completely filled out by the patient. Similar to BDCAF, the last 4 weeks are evaluated. It is a form consisting of a total of 10 questions that can be filled out very quickly. The first 6 questions are about mucocutaneous involvement, and the other questions ask about eye, gastrointestinal and vascular involvement. Its advantage is that it also asks how much each lesion bothers the patient. However, there is no weighting according to the types of involvement in this index as in BDCAF.
