Delayed referral of venous ulcers increases resource usage.

OBJECTIVE: Venous insufficiency is often not readily recognized as a contributing etiology to nonhealing wounds by nonvascular surgery specialists, potentially delaying appropriate treatment to achieve wound healing and increasing healthcare costs. The objective of the present study was to understand the time and resources used before the definitive treatment of venous ulcers. METHODS: A single-institution retrospective medical record review of C6 patients undergoing radiofrequency saphenous and perforator vein ablation from May 2016 to January 2018 identified 56 patients with 67 diseased limbs. The numbers of inpatient, emergency department, and wound care visits and the intervals to vein ablation from the initial evaluation of the ulceration by a healthcare provider were collected. The demographics, comorbidities, previous venous interventions, wound characteristics, duplex ultrasound imaging, and available wound healing follow-up through July 2018 were assessed for all patients. RESULTS: For the 67 limbs examined, 588 total healthcare visits were performed for wound assessment before a referral to a vascular surgeon, with 413 visits at a wound care center (70% of all visits). Other specialty visits included emergency medicine (17.9% of limbs) and rheumatology (22.4% of limbs). Six patients (nine limbs) were admitted to inpatient services for treatment of their ulceration. Overall, the patients were seen an average of 8.6 ± 9.7 times for their ulcer with the wound center before determination of a contributing venous etiology and subsequent treatment. These visits translated to a median of 230 days (interquartile range, 86.5-1088 days) between the first identification of the ulcer by healthcare providers and subsequent accurate diagnosis and definitive treatment of their venous disease with radiofrequency saphenous and perforator vein ablation. After intervention, 18.64% of the limbs had healed at 1 month, 33.92% had healed at 3 months, 50% had healed at 6 months, and 82.92% had healed by 12 months. CONCLUSIONS: An earlier and accurate diagnosis of the venous contribution to ulcers and subsequent appropriate treatment of venous etiologies in wound formation by a vascular venous specialist could significantly improve healing and minimize resource usage.
