Background
Healthcare workers have been overexposed to SARS-CoV2 during the current pandemic but there is little information on the impact of SARS-CoV2 on nephrologists. The aim of the present study was assessing SARS-CoV2 infections in nephrologists in the first and second pandemic wave, describing risk factors and clinical features.
Methods
This national survey was sent to Spanish nephrologists. Epidemiological data, comorbidities and medications were collected and compared between infected and non-infected nephrologists. Symptoms, prescribed treatments and outcomes are described for infected nephrologists.
Results
Three hundred and twenty-seven nephrologists (66% female, age 46±11 years) completed the survey. Of them, 62 (19%) were infected by SARS-CoV2. Infection was detected by rRT-PCR in the 37 symptomatic patients (62%) and by serological tests in 25 (38%) asymptomatic individuals. Five (8%) of the infected nephrologists were hospitalised. Contrary to the general population, most infections occurred during the first pandemic wave and, specifically, during the first month, when personal protective equipment (PPE) shortages were most severe. Factors associated to infection in univariate analysis were younger age (p = 0.004), work in non-Nephrology Departments (p = 0.045), higher exposure to COVID-19 patients (p < 0.001), lack of appropriate PPE (p < 0.001) and non-O ABO blood group. In an adjusted multivariate model, only lack of appropriate PPE remained predictive of infection (hazard ratio 3.5 [95% confidence interval 1.9-6.8], p < 0.0001).
Conclusions
SARS-CoV2 infection was frequent among nephrologists, it was frequently diagnosed late and was associated with working conditions.
