[Leg ulcers: Should general practitioners hospitalize their patients?]

Determine whether general practitioners have sufficient expertise in the field of leg ulcers.

A cross-sectional survey was conducted among 179 general practitioners working in the region Île-de-France to evaluate the implementation of leg ulcer guidelines issued by the Superior Health Authority (HAS) in 2006. Participating physicians were either internship supervisors or practitioners in Paris' 14th district.

The first hundred usable answers (response rate 65%) came from 71 internship supervisors and 29 practitioners of Paris' 14th district. Only 40% of the physicians were aware of the guidelines, with no significant difference noted between the two groups. 9/10 practitioners examined less than 10 patients with leg ulcers per year. Physical examinations were done according to the guidelines and a venous Doppler was prescribed in two thirds of the cases. The ankle-brachial pressure index (ABPI) essential to diagnose lower limb arteriopathy was measured for only 10% of the patients. In accordance with the guidelines, compression was by far (73%) considered as the main treatment as compared to dressing (37%), but compression therapy was well prescribed in only one-third of the cases. Despite poor prognosis criteria (characteristic and time course), referral for a specialized opinion was rare.

Even if they were not always aware of the detailed guidelines, the practitioners applied the main recommendations. Nevertheless, practices could be improved by measuring the ABPI, searching for a diagnosis of arteriopathy, and better prescription of compression therapy. General practitioners should refer patients with leg ulcers to a specialized hospital unit.
