Peripheral artery disease in Germany (2009–2018): Prevalence, frequency of specialized ambulatory care and use of guideline-recommended therapy – A population-based study

Background. Information on the association between earlobe crease (ELC) and peripheral artery disease is limited. We assessed this association in community-dwelling older adults. Study Design. A total of 294 Atahualpa residents aged ≥60 years were enrolled. ELC were visually identified by two raters. The ankle-brachial index (ABI), used as a surrogate of peripheral artery disease, was categorized using American Heart Association criteria. Using logistic regression and probability models, adjusted for demographics and cardiovascular risk factors, we assessed the relationship between ELC and abnormal ABI determinations, as well as the influence of age on this association. Results. ELC was identified in 141 (48%) individuals, and abnormal ABI determination was carried out in 56 (19%). The association between ELC and abnormal ABI was nonsignificant in logistic regression and probability models with individuals stratified according to their median age. Conclusions. The association between ELC and abnormal ABI determinations is probably attenuated by the high prevalence of both conditions in older persons. ELC might not be useful for identifying candidates for ABI determination.

Background. Little is known on the prevalence of peripheral artery disease (PAD) in developing countries.Study design. Population-based study in Atahualpa. InPhase I, the Edinburgh claudication questionnaire (ECQ) was used for detection of suspected symptomatic PAD; persons with a negative ECQ but a pulse pressure ≥65 mmHg were suspected of asymptomatic PAD. InPhase II, the ankle-brachial index will be used to test reliability of screening instruments and to determine PAD prevalence. InPhase III, participants will be followed up to estimate the relevance of PAD as a predictor of vascular outcomes.Results. DuringPhase I, 665 Atahualpa residents aged ≥40 years were enrolled (mean age: 59.5 ± 12.6 years, 58% women). A poor cardiovascular health status was noticed in 464 (70%) persons of which 27 (4%) had a stroke and 14 (2%) had ischemic heart disease. Forty-four subjects (7%) had suspected symptomatic PAD and 170 (26%) had suspected asymptomatic PAD. Individuals with suspected PAD were older, more often women, and had a worse cardiovascular profile than those with nonsuspected PAD.Conclusions. Prevalence of suspected PAD in this underserved population is high. Subsequent phases of this study will determine whether prompt detection of PAD is useful to reduce the incidence of catastrophic vascular diseases in the region.

Purpose: To estimate the positive predictive value of diagnosis and procedure codes for open and endovascular revascularization for peripheral artery disease (PAD) in Ontario administrative databases. Methods: We conducted a retrospective validation study using population-based Ontario administrative databases (2005-2019) to identify a random sample of 600 patients who underwent revascularization for PAD at two academic centres, based on ICD-10 diagnosis codes and Canada Classification of Health Intervention procedure codes. Administrative data coding was compared to the gold standard diagnosis (PAD vs. non-PAD) and revascularization approach (open vs. endovascular) extracted through blinded hospital chart re-abstraction. Positive predictive values and 95% confidence intervals were calculated. Combinations of procedure codes with or without supplemental physician claims codes were evaluated to optimize the positive predictive value. Results: The overall positive predictive value of PAD diagnosis codes was 87.5% (84.6%-90.0%). The overall positive predictive value of revascularization procedure codes was 94.3% (92.2%-96.0%), which improved through supplementation with physician fee claim codes to 98.1% (96.6%-99.0%). Algorithms to identify individuals revascularized for PAD had combined positive predictive values ranging from 82.8% (79.6%-85.8%) to 95.7% (93.5%-97.3%). Conclusion: Diagnosis and procedure codes with or without physician claims codes allow for accurate identifi-cation of individuals revascularized for PAD in Ontario administrative databases.
