Clinical Trial Summary

The purpose of this study is to assess the utility of the Modified version of VascuQol Scale as an effective biopsychosocial assessment tool for patients suffering from lower extremity peripheral arterial disease.

Description:

In the prior study, the original 25-item VascuQol Scale demonstrates the limitation of dimensional mixing. As a result, we suggest improving the original scale by integrating the five dimensions and simplifying the objects. 480 patients will be recruited to complete the Chinese version of VascuQol Scale and the modified version. Reliability, validity, responsiveness, and diagnostic accuracy for CLTI will be used to evaluate whether the modified scale could serve as an effective biopsychosocial assessment tool for patients suffering from lower extremity peripheral arterial disease.

Study Procedures :

After signing the informed consent form, eligible patients and/or their legal guardians will complete the questionnaires.

Outcome measures:

Patient-Reported Outcomes via specific questionnaires

Participant numbers:

480 patients will be recruited

Data management:

Data will be collected directly from the patients. All paper patient records will be kept in locked filing cabinet. Electronic files will be saved on password protected folder

Oversight :

i) Data will be collected in a electric database; ii) all documents containing the identity of the participating subjects (non-objection, list of correspondence, etc.) will be kept away from personal data; iii) If it is a computerized document, it will be kept on the center's information server with access control by password.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	the Modified version of VascuQol Scale	It is one of the frequently used scales to measure quality of life in patients with lower extremity arterial disease. It evaluates 5 different categories such as the symptom, social, activity, pain and emotional with a total of 25 sub-items. A 7-point Likert system is used to score this scale. It is sufficient for each item to check the corresponding boxes. In Modified version,we adjusted the questionnaire items and structure based on the the Chinese version and results of the previous reserach.	pre-operation;1-month;3-month;6-month;12-month

In Chinese version,not only did we complete cultural adaptation, but we used the emoji-based visual analogue scale to help patients fill out the scales.	pre-operation;1-month;3-month;6-month;12-month
Secondary	Ankle brachial index(ABI)	The ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD). The ABPI is calculated by dividing the systolic blood pressure at the ankle by the systolic blood pressure in the arm.	pre-operation;6-month;12-month
Secondary	EQ-5D-5L Scale	EQ-5D is a standardised measure of health-related quality of life developed by the EuroQol Group to provide a simple, generic questionnaire for use in clinical and economic appraisal and population health surveys. EQ-5D assesses health status in terms of five dimensions of health and is considered a 'generic' questionnaire because these dimensions are not specific to any one patient group or health condition.	pre-operation;1-month;3-month;6-month;12-month
