Abstract 14094: Use of a Spanish-translated Edinburgh Claudication Questionnaire for Detection of Peripheral Arterial Disease in an Outpatient Setting
Introduction: The Edinburgh Claudication Questionnaire (ECQ) is a well validated English-based screening measure to diagnose peripheral arterial disease (PAD). A similar Spanish-based validated questionnaire is lacking. We determined the ability of a Spanish-translated ECQ to accurately detect PAD in a predominantly Spanish-speaking population and whether certain baseline characteristics significantly impacted questionnaire performance.
Methods: We constructed a Spanish version of the ECQ and administered it to all participating Spanish-speaking outpatients without known PAD at a busy Los Angeles County cardiology clinic from October 2014-March 2015. Patients who answered “yes” to at least one of the questions were suspected to have PAD, and were then offered ankle brachial index (ABI) testing. An ABI value of <0.9 confirmed a PAD diagnosis. Standard t-test and chi squared testing were performed to determine baseline characteristics associated with a low ABI.
Results: Of the 917 completed Spanish-translated ECQs, 319 (35%) were positive for suspected PAD; 159 (50%) of these patients underwent ABI testing. The mean age was 58 years, and 50% were female. Only 23 (15%) of 159 patients were confirmed to have PAD with a low ABI (Table 1). Baseline characteristics associated with confirmed PAD included female sex, prior stroke, chronic kidney disease, osteoarthritis, and lower hemoglobin. The presence of congestive heart failure was associated with a higher likelihood of a false positive questionnaire.
Conclusions: Our Spanish-translated questionnaire was ineffective as a PAD screening tool. Sample size was small and limited to cardiology outpatients, with congestive heart failure accounting for nearly one-quarter of false positives. Further study is needed in large, primary care populations to provide further insight into questionnaire effectiveness and determine possible changes that may improve accuracy.
