Hypothesis
The Edinburgh Claudication Questionnaire (ECQ) may not be as accurate for diagnosing peripheral artery disease in 1st generation Black African-Caribbean and South Asian UK migrants.
Conclusion
The ECQ is less sensitive and specific for diagnosing intermittent claudication in these minority ethnic groups compared to previous studies.
Supporting Evidence
- The ECQ was found to have lower sensitivity and specificity in minority ethnic groups compared to previous validations.
- Only 5.4% of participants in the E-ECHOES study were eligible for this sub-study.
- The study used an objective measure (ABPI) to diagnose PAD, which may have affected the questionnaire's accuracy.
Takeaway
This study looked at how well a questionnaire works for finding leg pain in certain groups of people, and it found that it doesn't work as well as it does for others.
Methodology
Participants were recruited from a community screening study and completed the ECQ in their preferred language, followed by Ankle Brachial Pressure Index (ABPI) measurement.
Potential Biases
Younger non-responders may have affected the results, and the inclusion of illiterate participants could have contributed to lower accuracy.
Limitations
The study had a small sample size and only a fraction of eligible participants returned for ABPI assessment.
Participant Demographics
Mean age was 65 years, with 53% male and 29.5% illiterate.
