A routine monthly laboratory examination of the dialysis population and a serotypto-positive assessment of severe acute respiratory syndrome (SARS-Cov-2) in this population can help to produce more realistic, fair and repeatable results.
In this cross-sectional study, the researchers received samples from approximately 1,300 dialysis facilities across the United States, and by July 2020, the remaining plasma of 28,503 randomly selected adult dialysis patients had been tested for the new coronary pneumonia virus virus (100% sensitivity, 99.8% specificity).
extracted data on age, gender, race, residence, and facility zip codes from anonymous electronic health records, linking patient-level residence data to cumulative, daily cases, deaths, and nasal swab-testing rates per 100,000 population to assess the positive rates for dialysis and new coronary pneumonia virus in the U.S. population.
the age, gender, race and ethnicity distribution of the dialysis population in the United States is similar to that of the general population, but the proportion of older persons, men and those living in black and Hispanic neighborhoods is higher. the serum-positive rate of SARS-Cov-2 in the
sample was 8.0%, and the standard serum-positive rate was 8.3% for dialysis population in the United States and 9.3% for adult populations in the United States.
the U.S. dialysis population, the region with the lowest serotyt positive rate was in the West, at 3.5 percent, and in the Northeast, at 27.2 percent.
the sero-positive rate of 9.2 per 100,000 people, which is highly correlated with the number of deaths per 100,000 population (Spearman's ρ-0.77).
hispanics (OR-3.9) and Hispanic neighborhoods (OR-2.3) were more likely to be seroty-positive than other races.
sero-positive rate (OR=10.3) for the population of the communities with the highest population density, significantly higher than that of the community residents with the lowest density of one fifth.
in early March 2020, the positive rate in areas where the embargo was imposed and where work aggregation was reduced by at least 5 per cent (OR=0.4) was significantly lower than in areas where the above measures were only implemented in July.
study concluded that sars-CoV-2 antibody-positive rates in the adult population of the United States were about 10% in the first wave of the new corona pneumonia pandemic, and that social distance and patient isolation were the most effective means of limiting the spread of the virus, especially in ethnic minorities and densely populated areas.
