{Abstract}: <B>OBJECTIVE: </B>Peripheral arterial disease (PAD) can reduce wound healing rates by ≤30%. Current literature suggests wound outcomes are improved when management is driven by vascular providers. However, whether this benefit is derived solely from early vascular provider involvement remains unclear.<BR><B>METHODS: </B>A retrospective analysis was performed of 80 limbs with chronic wounds and underlying PAD seen at our institution's wound center between July 2022 and July 2023. Arterial disease was defined by the following criteria: (1) prior PAD diagnosis, (2) ankle-brachial-index of <0.9 or toe pressure of <70 mm Hg, or (3) absent peripheral pulses. Patients were divided into early (<6 week) vascular provider exposure (EVE; n = 45) or late/no vascular exposure (LNVE; n = 35). Providers included vascular surgeons and affiliated advanced practitioners. The primary outcome studied was overall time to wound healing. Statistical analysis included χ2 tests, t test, Pearson correlation, Kaplan-Meier analysis, and Cox regression modeling (variables included in a multivariate model if univariate effect on healing was associated at P < .1).<BR><B>RESULTS: </B>Baseline demographic profiles were similar between groups with exception of lower baseline albumin (P = .037), more heart failure (P = .013), and more prior peripheral endovascular interventions (P = .013) in the EVE group. Although the initial wound locations and sizes were similar, EVE wounds had significantly higher WIfI wound scores (1.9 ± 0.1 vs 1.6 ± 0.1; P = .039). Although more LNVE patients developed radiographic osteomyelitis (31.8% vs 55.6%; P = .033), fewer underwent operative debridement or amputation (100% vs 63.2%; P = .008). On univariate analysis, healing time tended to be shorter in EVE, but not significantly (P = .089). When controlled for comorbidities, however, healing rates were nearly two-fold higher in EVE (hazard ratio, 2.42; 95% confidence interval, 1.21-4.84). LNVE wounds also took significantly longer to reach checkpoints including time to >75% granulation (P = .05), 15% weekly size decrease (P = .044), and epithelialization (P = .026). LNVE patients required more wound center visits (P = .024) and procedures (P = .005) with a longer time to intervention (P = .041). All EVE patients obtained ankle-brachial indices, with 90.9% of them available at their first wound care visit (P < .001). Although a slightly greater proportion of patients underwent a major amputation in EVE (15.6% vs 11.4%; P = .595), this difference did not attain significance; additionally, 100% of EVE patients had documented discussion of nonsalvageable limbs before amputation.<BR><B>CONCLUSIONS: </B>Early exposure to vascular practitioners improves wound healing time, timeliness to intervention, and wound center and hospital resource use in patients with PAD. Further investigation into benefits of vascular involvement within community wound center models could significantly improve awareness and accessibility of arterial wound care in smaller/remote communities.
