New research being presented at the European Association for the Study of Diabetes (EASD), held online this year (27 Sept-1 Oct), reveals how Belgium’s efforts to maintain a diabetic foot care program during the COVID-19 pandemic can offer valuable lessons to the rest of the world.
“Thanks to the great efforts of diabetic foot clinics, where to buy cheap proventil usa without prescription continued availability of diabetic foot ulcer services during lockdown, although in a limited capacity, were really helpful, and may be the reason why we didn’t see late presentation and the impact on the severity of ulcers was limited to slightly larger wounds”, says lead author Dr. An-Sofie Vanherwegen from Sciensano, Brussels, Belgium. “Our findings will hopefully guide diabetic foot clinics in serving their patients using innovative strategies, such as telemedicine, during the current, and eventual future, public health crises.”
It is estimated that around a quarter of all people living with diabetes worldwide will develop a foot ulcer in their lifetime. The ulcers develop as diabetes damages the nerves and blood supply to the feet. Without timely treatment, these ulcers are hard to heal and form the leading cause of lower limb amputations in Western countries.
In 2005, a national diabetic foot care program (IQED-Foot) was established in Belgium, that has resulted in 34 multidisciplinary diabetic foot clinics recognized by the Belgian Ministry of Health for the treatment of diabetic ulcers. Since then, a clear decline in the lower-limb amputation rate has been noted in Belgium.
“As the COVID-19 pandemic unfolded, there were concerns about the impact on Belgians with diabetic foot ulcers. People need to be seen quickly if an ulcer begins to form—that gives diabetic foot clinics the greatest chance of treating the wound successfully”, explains Vanherwegen.
A national lockdown in Belgium between March 14th and May 3rd 2020, placed restrictions on free movement and only urgent care was provided in hospitals. However, diabetic foot clinics were advised by professional associations to consider all active diabetic foot problems as urgent.
To gauge the impact of the pandemic on the presentation rate and severity of diabetic foot ulcers in these clinics, researchers distributed a survey to the recognized clinics across Belgium asking about the measures they had taken during and after the lockdown to maintain their activities. A total of 24 diabetic foot clinics participated in the survey.
During the lockdown, one clinic closed, but the 23 others remained open for urgent care, whilst applying COVID-19 measures—almost three-quarters (71%) of clinics selected patients based on urgency and high risk for ulceration; whilst 79% reported partially switching to remote consultations; 13 clinics (54%) reduced the frequency of consultations for patients ; and half spread out patient appointments during the day to allow for physical distancing.
Between January 1st and September 30th, 2020, patient and ulcer characteristics were recorded by 22 foot clinics for 887 consecutive patients presenting with new moderate to severe diabetic foot ulcers—a big enough sample for it to be representative of the picture across Belgium. Patients were assigned to three groups based on the date of first contact with the clinic—pre-lockdown (322 patients), during lockdown (93), and post-lockdown (472)—and compared to data from the same time period of the IQED-Foot data collection in 2018. No differences in patient characteristics (eg, age, gender, medical history, diabetes type and duration) were noted between the groups.
The study found that compared to the same time period in 2018, the average weekly presentation rate of patients during lockdown was substantially reduced (by almost 60%―from 1.4 patients per week in 2018 to 0.6 patients per week in lockdown). However, there was no change in average patient-reported delay in presentation, although patients during and after lockdown tended to present with slightly larger ulcer. No significant differences in depth, infection or loss of protective sensation were detected between the three groups.
