RESUMEN
AIMS: The establishment of a vascular surgeon-led emergency diabetic foot service in 2006 has evolved to provide lower limb wound care for patients with and without diabetes. We aimed to determine whether the service was associated with sustained, improved limb salvage rates for the whole population, analyse key aspects of service provision and compare outcomes against published studies. METHODS: The vascular unit serves a largely rural population of approximately 240,000. Data was collected prospectively on lower limb amputations, arterial and minor surgical interventions from 2006 to 2015, and retrospectively retrieved for 2004-2005, prior to service commencement. Data was also collected on referral patterns, volume of patient admissions and attendances, and delays. Lower limb amputation rates were compared against published data and analysis of admission trends and delays employed non-parametric tests. RESULTS: Age/gender adjusted major lower limb amputations for the populations with and without diabetes were 412/100,000 in 2004 and 15/100,000 in 2005 respectively. Following service introduction, major amputations reduced and since 2012 have been sustained at between 15-44/100,000 and 1-3/100,000 for patients with and without diabetes respectively, comparing favourably with published data. Vascular interventions have remained static, but referrals of patients directly to the service and numbers of minor procedures have increased. CONCLUSIONS: The sustained decreases in all major lower limb amputations that have coincided with the development of a core team approach to providing rapid access and comprehensive care for patients with emergency diabetic foot problems may indicate that this service design benefits patients with and without diabetes.
