Diabetes-related foot complications are a major cause of amputation. The presence of peripheral arterial disease (PAD) identifies those at increased risk of ulceration, failure to heal an ulcer, and amputation. This systematic review assesses the ability of noninvasive screening tests to detect PAD in patients with diabetes mellitus. A database search was performed using the OVIDSP Web site, from 1946 to June 30, 2012 (MEDLINE®), and from 1974 to June 30, 2012 (EMBASE), to identify studies assessing the utility of screening tests in detecting PAD or predicting clinical outcomes in patients with diabetes mellitus. Thirteen studies were identified that reported sensitivity and specificity data on screening tests. No single screening test was reliable in identifying or excluding peripheral arterial disease in patients with diabetes. Although the evidence base is limited, transcutaneous oxygen measurements appear to be predictive of ulcer or surgical wound healing. The diagnosis of PAD (and the decision to revascularize) in patients with diabetes is unreliable using screening tests. Therefore, all patients with diabetes-related foot ulceration should be assessed by a multidisciplinary diabetes foot team that has access to a vascular specialist. A low threshold for noninvasive diagnostic imaging seems appropriate in patients with diabetes-related foot ulceration.

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012307 Risk Factors An aspect of personal behavior or lifestyle, environmental exposure, inborn or inherited characteristic, which, based on epidemiological evidence, is known to be associated with a health-related condition considered important to prevent. Health Correlates,Risk Factor Scores,Risk Scores,Social Risk Factors,Population at Risk,Populations at Risk,Correlates, Health,Factor, Risk,Factor, Social Risk,Factors, Social Risk,Risk Factor,Risk Factor Score,Risk Factor, Social,Risk Factors, Social,Risk Score,Score, Risk,Score, Risk Factor,Social Risk Factor
D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D015203 Reproducibility of Results The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results. Reliability and Validity,Reliability of Result,Reproducibility Of Result,Reproducibility of Finding,Validity of Result,Validity of Results,Face Validity,Reliability (Epidemiology),Reliability of Results,Reproducibility of Findings,Test-Retest Reliability,Validity (Epidemiology),Finding Reproducibilities,Finding Reproducibility,Of Result, Reproducibility,Of Results, Reproducibility,Reliabilities, Test-Retest,Reliability, Test-Retest,Result Reliabilities,Result Reliability,Result Validities,Result Validity,Result, Reproducibility Of,Results, Reproducibility Of,Test Retest Reliability,Validity and Reliability,Validity, Face
D015897 Comorbidity The presence of co-existing or additional diseases with reference to an initial diagnosis or with reference to the index condition that is the subject of study. Comorbidity may affect the ability of affected individuals to function and also their survival; it may be used as a prognostic indicator for length of hospital stay, cost factors, and outcome or survival.
D015995 Prevalence The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time. Period Prevalence,Point Prevalence,Period Prevalences,Point Prevalences,Prevalence, Period,Prevalence, Point,Prevalences
D017719 Diabetic Foot Common foot problems in persons with DIABETES MELLITUS, caused by any combination of factors such as DIABETIC NEUROPATHIES; PERIPHERAL VASCULAR DISEASES; and INFECTION. With the loss of sensation and poor circulation, injuries and infections often lead to severe foot ulceration, GANGRENE and AMPUTATION, SURGICAL. Foot Ulcer, Diabetic,Diabetic Feet,Feet, Diabetic,Foot, Diabetic
D042241 Early Diagnosis Methods to determine in patients the nature of a disease or disorder at its early stage of progression. Generally, early diagnosis improves PROGNOSIS and TREATMENT OUTCOME. Early Detection of Disease,Diagnosis, Early,Disease Early Detection
