Lessons Learned: A Disruption in Care Leads to Increased Rates of Proximal Amputations.

BACKGROUND

In March 2020, due to the COVID-19 pandemic, hospitalizations in New York state were restricted to emergency purposes. Non-COVID related cases involving lower extremity wounds were only admitted for acute infections and limb salvage. Patients with these conditions were placed at higher risk for eventual limb loss.

PURPOSE: To understand the impact of COVID-19 on amputation rates.

METHODS

A retrospective review of lower limb institution-wide amputations was conducted at Northwell Health from January 2020 to January 2021. The amputation rates during the COVID-19 shutdown period were compared to the pre-pandemic, post-shutdown, and reopening period.

RESULTS

The pre-pandemic period had 179 amputations, of which 8.38 % were proximal. 86 amputations were performed during shutdown, with a greater proportion being proximal (25.58 %, p=0.0009). Following the shutdown period, amputations returned to baseline. The proportion of proximal amputations during post-shutdown was 18.5 % and during reopening was 12.06 %. Patients had 4.89 times higher odds of undergoing a proximal amputation during the shutdown period.

CONCLUSIONS

The effect of COVID-19 on amputation rates demonstrates an increase in proximal amputation during the initial shutdown. This study suggests an indirect negative effect of COVID-19 hospital restrictions on surgeries during the initial shutdown period.
