RESUMO
Guidelines based on randomized controlled data recommend patients with newly diagnosed venous leg ulcers (VLUs) to undergo venous reflux duplex ultrasound (US) and be considered for treatment with pentoxifylline to accelerate ulcer healing. A retrospective review was conducted of 2,061 patients with VLU diagnosed between 2011 and 2020 in a rural health care system to identify factors associated with increased or decreased likelihood of being prescribed venous reflux duplex US and pentoxifylline. Venous reflux duplex US (16%) and pentoxifylline (0.7%) were prescribed infrequently. Evaluation by a vascular specialist was associated with a significantly increased frequency of undergoing venous reflux duplex US (5%-38%). Seeing a wound care specialist was associated with an increased frequency of being prescribed pentoxifylline (0.7%-1.4%). Increased referral to specialists and/or referring clinician education on guideline-based care may be of benefit to patients with VLUs. Pentoxifylline seems underused, even by specialists. Further study is needed to confirm these findings and determine whether they are generalizable.
