Abstract
Background In patients who have a venous leg ulcer, very little is known about the frequency of their concomitant medical conditions. Objectives To evaluate the frequency that other medical conditions are associated with a new venous leg ulcer. Methods We studied a 10% random sample of elderly patients registered in the General Practice Research Database between 1988 and 1996. We describe the frequency of medical conditions using simple percentages. In order to assess the associations between medical conditions and the onset of a venous leg ulcer, we used logistic regression models. Results Several medical conditions occur commonly in patients who develop venous leg ulcers, including anaemia, angina, asthma, cellulitis of the lower extremity, depression, diabetes, limb oedema, hypertension, osteoarthritis, pneumonia and urinary tract infection. After statistical adjustment many medical conditions were significantly associated with those who had recent onset of a venous leg ulcer, including asthma, cellulitis of the lower extremity, congestive heart failure, diabetes, deep venous thrombosis, lower limb oedema, osteoarthritis, peripheral vascular arterial disease of the lower extremity, rheumatoid arthritis, history of hip surgery, and history of venous surgery/ligation. Unexpectedly, some illnesses were inversely associated with those that had recent onset of a venous leg ulcer, including angina, cerebral vascular accident, depression, malignancy, myocardial infarction, pneumonia and urinary tract infection. Conclusions Physicians caring for individuals with venous leg ulcers need to be aware that it is likely that these individuals may have one of the comorbid illnesses listed above.
