New Study Suggests Patients With Diabetes Are Three Times More Likely To Develop Severe COVID-19 Complications

A recently published study in Diabetes Care reinforces the notion that patients with diabetes are at an increased risk of developing severe COVID-19-related complications.1

In this prospective cohort study, Gregory and colleagues surveyed the medical records of over 6,000 patients within the Vanderbilt University Medical Center health system (between March and August 2020) and found that patients with type 1 diabetes (n=40) and type 2 diabetes (n=273) were more than three times as likely as patients without diabetes (n=6138) to develop severe COVID-19-related complications, including greater severity of illness, hospitalization and death.1

Furthermore, when focusing specifically on patients with type 1 diabetes, the study authors found a significant association between severity of illness and factors such as glycosylated hemoglobin (HbA1c), hypertension, race, recent diabetic ketoacidosis, status of health insurance and less use of diabetes technology (i.e. a continuous glucose monitor).1    

In fact, according to a recent analysis by The New York Times, there has been a 15 percent increase in diabetes-related deaths since the start of the current pandemic (March to November 2020).2 Remarkably, according to the same analysis, approximately 512,000 more Americans died (between March 15, 2020 and January 30, 2021) than would have in a normal year, including deaths not directly attributable to COVID-19, representing a 20 percent increase.3 Basing their analysis on mortality data from the Centers for Disease Control and Prevention (CDC) National Center for Health Statistics, The New York Times investigators used excess deaths (“typically defined as the difference between the observed numbers of deaths in specific time periods and expected numbers of deaths in the same time periods”) as a basis for quantifying the impact of the current pandemic.3,4 As official death counts continue to take place, these numbers may actually represent an undercount.  

In terms of the lower extremity, several recent studies describe the increased severity of diabetic foot-related complications and incidence of amputations observed during the current pandemic.5-8 We need look no further than our own practices to understand the potential risks involved in delaying or even postponing care for this most vulnerable population. Whether it is at-risk diabetic foot care (including serial nail, corn and callus debridements), care of the diabetic foot in remission or complex ulcer and amputation care, we bear the burden of protecting our patients from limb loss while ensuring their safety and well-being in terms of minimizing COVID-19 exposure. 

As Rogers and colleagues note, “increased awareness, proper prioritization, and efficiencies of care in lower risk settings are the first steps in mitigating this parallel pandemic of diabetes-related amputations.”9 Moreover, we must maintain a proactive approach to amputation prevention during the current pandemic while adapting to changes in the current practice model. Never has the role of the podiatric profession been so critically important and intertwined with the health and well-being of our nation as today. Let us embrace this challenge head-on.
