Abstract

Introduction: The increasing prevalence of diabetes mellitus and advances in endovascular therapies continue to have an impact on the epidemiology and management of lower extremity arterial disease. This study describes trends in lower extremity revascularisation and major lower limb amputation in NHS England over the past two decades (2000-2019).

Methods: Numbers of lower extremity endovascular interventions, open surgical procedures and major lower limb amputations performed in NHS England between 2000 and 2019 were extracted from publicly available hospital admitted patient care activity reports. Trends in intervention were assessed with linear regression models and chi-square tests for trend.

Results: Over this period, 527,131 revascularisations and 92,053 amputations were performed. The mean age of patients was 67.5 years (standard deviation 1.6 years) and 65.3% were male. The number of lower limb revascularisation procedures increased by 402.4 units/year (95% confidence interval, CI, 290.1-514.6, p < 0.001). The number of endovascular interventions rose by 43.5% (10,912 in 2000 vs 15,657 in 2019; β = 359.5.0, 95% CI 279.3-439.8, p < 0.001) compared with no significant increase in the number of open surgical procedures (8,483 in 2000 vs 7,872 in 2019; β = 42.8, 95% CI -8.3 to 94.0, p = 0.095). The number of major lower limb amputations has decreased by 9.4% (5,418 in 2000 vs 4,907 in 2019; β = -31.0; 95% CI -49.6 to -12.5, R2 = 0.42, p = 0.003).

Conclusions: There has been a significant increase in the rate of lower limb revascularisation procedures associated with decreased numbers of major lower limb amputations over the past two decades. These changes in overall trends may affect both service provision and vascular surgery training planning.
