Impact of COVID-19 Pandemic on Clinical Care of Peripheral Arterial Disease Patients: A Single-Center Experience.

OBJECTIVE

To better manage the burden of the COVID-19 pandemic on hospitals, numerous scheduled procedures have been postponed nationwide.

DESIGN AND METHODS

Retrospective analysis of patient characteristics and outcomes of patients hospitalized with peripheral arterial disease (PAD) in the period prior to the COVID-19 pandemic (2018 and 2019) and during the pandemic (2020 and 2021). This study assesses the in-hospital outcomes. Main endpoints are Rutherford stages at admission for intervention, incidence of amputation, of total occlusion, and duration of intervention. The data were analyzed descriptively.

RESULTS

The total number of interventions due to PAD had decreased in 2020, but not significantly during the pandemic period ( = 5351) compared to the period prior to COVID-19 pandemic ( = 5351) ( = 0.589). The proportion of interventions treated for critical limb-threatening ischaemia (CLTI) increased from 2018/2019 ( = 2112) to 2020/2021 ( = 2426) ( < 0.001). However, the proportion of patients with wounds requiring amputation was not higher during the pandemic ( = 191) than before ( = 176) (minor amputations = 0.2302, major amputations = 0.9803). The proportion of total occlusions did not differ significantly between the pre-COVID-19 ( = 3082) and the COVID-19 pandemic periods ( = 2996) ( = 0.8207). Multilevel interventions did not increase significantly from 2018/2019 ( = 1930) to 2020/2021 ( = 2071). Between 2018/2019 and 2020/2021, the procedure duration and fluoroscopy duration increased significantly. However, parameters such as contrast agent volume and radiation dose did not differ significantly. The average length of stay was 4.6 days.

CONCLUSION

The COVID-19 pandemic had an impact on the in-patient care of PAD patients in terms of disease stage severity and complexity. However, the amputation rate was not affected.
