OUTPATIENT TREATMENT OF CHRONIC VENOUS ULCERS IN A SPECIALIZED CLINIC

Abstract

Chronic leg ulcers have many different causes and therefore need an accurate diagnosis in order to give the most effective treatment. A specialized clinic was set up in Fremantle Hospital in July 1988 with the aims of performing a thorough clinical and laboratory assessment to establish the cause of ulceration in every patient, and treating patients according to the cause of ulceration. Patients with arterial, neoplastic or dermatological conditions were treated as appropriate for their diagnosis and patients with other chronic ulcers were managed as outpatients where possible. Patients were seen between July 1988 and July 1989. Only 43% had purely venous ulcers, 32.6% had a venous component plus some other abnormality, and 5.2% were purely arterial. Using an outpatient treatment regimen, 67% of all ulcerated limbs and 73.7% of limbs with purely venous ulcers were healed within 6 months. Only 11 patients with venous ulceration (15 limbs) failed on this therapy and required admission during the observation period. The initial ulcer size was shown to influence the time to total healing of the limb. The healing rates achieved compare favourably with studies from other specialized centres and suggest that the majority of patients with chronic leg ulcers can be treated successfully using ambulatory outpatient dressing techniques.
