The Global Status and Recurrence of Diabetic Foot Ulcers

Importance of early detection and management
(Epidemiology and Recurrence Rate of DFU)

A diabetic complication that can not be underestimated – Diabetic Foot Ulcer (DFU)

There are over 500 million people with diabetes globally, and approximately 18 million are at risk of developing 'Diabetic Foot Ulcers' each year.1,2Remarkably, up to 34% of individuals with diabetes may experience DFU during their lifetime.2Remarkably, up to 34% of individuals with diabetes may experience DFU during their lifetime.

Prevalence of DFU: Global Current Status and Challenges

The global prevalence of diabetic foot ulcers is around 6.3%, with continental rates as follows: North America 13.0%, Africa 7.2%, Asia 5.5%, Europe 5.1%, and Oceania at 3.0%.3The physiological and psychological impacts of DFU on patients, as well as the burden on global healthcare systems, are significant and should not be overlooked. If not treated promptly, foot ulcers can further progress to infections, gangrene, and in severe cases, even require amputation.2

Taiwan has a low prevalence of DFU, but vigilance against risk is still needed

The global prevalence of DFU is approximately 6.3%. However, in Taiwan, the prevalence of DFU is only 0.5% to 0.9%.4Despite the lower prevalence, we still need to be vigilant about the risk of incidence or recurrence, as the disease can have a significant impact on both physical and psychological well-being.

The Challenge of Treatment：Recurrence Rate of Ulcers

After healing from a Diabetic Foot Ulcer (DFU), about 40% of patients will experience a recurrence within one year, and nearly 60% of patients will be affected by a DFU again within three years.5

The Importance of Early Detection and Care Knowledge

Beyond the challenges of treatment, the importance of early detection and care knowledge is emphasized. Raising awareness among patients and their families about the warning signs of early skin damage due to DFUs, understanding when it is necessary to seek medical attention promptly, and so on, can have a positive and proactive effect on preventing the recurrence of ulcers if these potential factors can be identified and preventative treatment is administered in a timely manner.5
