Estimating Recent US Limb Loss Prevalence and Updating Future Projections

Area of Science:

• Public Health
• Epidemiology
• Amputation Studies

Background:

• Limb loss is a significant public health concern in the United States.
• Understanding the prevalence and trends of limb loss is crucial for resource allocation and healthcare planning.

Purpose of the Study:

• To estimate the current prevalence of limb loss in the US by etiology and anatomical location.
• To project future trends in limb loss prevalence over the next 40 years.

Main Methods:

• Utilized the National Inpatient Sample (NIS) database for comprehensive US healthcare data.
• Employed linear regression models to forecast limb loss prevalence based on incidence and disease duration.
• Analyzed data from community hospitals within the NIS database.

Main Results:

• In 2019, an estimated 2,309,000 individuals were living with limb loss in the US.
• Lower extremity amputations accounted for approximately 91% of all limb loss cases.
• Projected a 145% increase in limb loss by 2060, with diabetes and vascular disease as primary drivers.

Conclusions:

• Current limb loss prevalence estimates are higher than previously projected, largely due to increasing rates of diabetes and peripheral vascular disease.
• Emphasizes the critical need for research in limb preservation and amputation optimization strategies.
• Highlights the importance of proactive healthcare resource allocation to address the growing limb loss epidemic.
