[COVID-19 crisis management during the first three waves in a large dialysis organisation: Feedback from NephroCare France]. / Gestion de la crise COVID-19 dans une organisation multicentrique de dialyse au cours des trois premières vagues : retour d'expérience de NephroCare France.

ABSTRACT

At the start of the COVID crisis, NephroCare operated 40 dialysis units in 7 regions, with 2,740 hemodialysis patients. The national COVID-19 crisis team implemented early the necessary measures to ensure the safety of dialysis patients and caregivers in the context of the pandemic. These measures were mostly traditional, but some were specific to our organization. They were modified during the 3 successive waves. The first wave mainly impacted NephroCare Ile-de-France which recorded 75% of the contaminations with an impact on the dialysis parameters of non-COVID patients which was not found during the second wave due to reduced stress (34% of contaminations) and a better management of COVID+ patients. The effectiveness of the measures put in place is suggested by the absence of PCR+ in asymptomatic patients and the perfect adequacy of the anti-SARS-CoV2 antibodies with the diagnosis of COVID in one severely impacted Ile-de-France unit, opposite to literature reporting significant rates of positive PCR or serology in asymptomatic patients. In addition, the contamination rate was calculated below the national rate reported by the Biomedicine Agency. The third wave was marked by the implementation of the anti-SARS-CoV2 vaccination with a proportion of vaccinated patients not different from national data and a decrease in COVID cases at the end of the third wave while the national incidence remained stable on the period. In conclusion, this experience of facing an unprecedented serious situation showed the responsiveness of the organization, significant innovations and the efficacy of the implemented measures.
