Primary Outcome Measures:
  • Proportion of questionnaires with errors after self completion [ Time Frame: 1 day ] [ Designated as safety issue: No ]
    Analysis of first inclusion only in patients that are included multiple times over the study period. Predetermined score for the WELCH questionnaire answers [(4 items); (4 additions & 1 multiplication)] and WIQ... estimation of the percentage of errors with 95% confidence interval. Comparison of the two percentages

Secondary Outcome Measures:
  • Correlation with ankle brachial index (ABI) [ Time Frame: 1 day ] [ Designated as safety issue: No ]
    Analysis of first inclusion only in patients that are included multiple times over the study period. Calculation of questionnaire scores from predetermined methods and analysis of the coefficient of determination and coefficient of correlation to minimal ABI

  • Correlation with treadmill result [ Time Frame: 1 day ] [ Designated as safety issue: No ]
    Analysis of first inclusion only in patients that are included multiple times over the study period.Calculation of questionnaires score from predetermined methods and analysis of the coefficient of determination and coefficient of correlation to maximal walking distance on treadmill, in the subgroup of patients that have a routine treadmill scheduled during the visit.

  • Facility of the scoring of the questionnaires [ Time Frame: 1 day ] [ Designated as safety issue: No ]
    Proportion of WELCH scores calculated by physician and comparison to the proportion of WIQ score calculated by physicians as a estimation of the facility to calculate the score by mental calculation in routine

  • Reliability of the questionnaire [ Time Frame: 3 weeks ] [ Designated as safety issue: No ]
    Comparison of the scores of the WELCH in the patients that may be seens within 3 weeks of their first inclusion, for any reasons, (e.i. seen first for a doppler and two weeks later for a treadmill test)over the study period. Analysis of the reliability through the coefficient of variation of the score.

  • sensitivity of the WELCH to changes [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Comparison of the scores of the WELCH in the patients that may be seens within 1 year from their first inclusion, for any reasons, (e.i. seen follow up of their disease)over the study period. Analysis of the changes of the score to changes of the ABI. Analysis of the changes of the score to changes in maximal walking distance if available.

Estimated Enrollment: 800
Study Start Date: September 2011
Estimated Study Completion Date: November 2013
Estimated Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
suspected PAD patients
Patients suspected of peripheral artery disease and, as such, referred for a vascular investigations
Other: Questionnaire
Self completed questionnaire, Supervised by the physician Ankle brachial index (ABI) calculation Maximal walking distance (MWD) on treadmill or over the 6 minutes walking test (when available)
Other Names:
  • Walking impairment questionnaire (WIQ)
  • Walking estimated limitation calculated by history (WELCH)

Detailed Description:

Two questionnaires the WELCH and the "walking impairment questionnaire" (WIQ) are submitted to patients referred for vascular investigations for suspêcted peripheral arterial disease (PAD). Comparison of score to hemodynamic parameters (first goal) or maximal walking distance (MWD) on treadmill (secondary goal). Scoring of the WIQ is performed according to references. Scoring of the WELCH has been submitted for copyright protection (involves a series of 4 additions a subtraction and a single multiplication)


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population

Patients referred for arterial vascular investigation regardless of whether they are prooved for peripheral arterial disease, or not.


Inclusion Criteria:
