Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Healthcare Management

Background:

  • Healthcare personnel are at high risk of COVID-19 exposure.
  • Rapid antigen testing offers a potential tool for frequent screening.
  • Previous studies on daily antigen testing in healthcare settings are limited.

Purpose of the Study:

  • To evaluate the feasibility and performance of a daily antigen testing program for healthcare personnel.
  • To assess the accuracy and acceptability of antigen tests in a real-world healthcare environment.

Main Methods:

  • A retrospective analysis of antigen testing data from December 2020 to April 2021.
  • Data collected from 5 forensic psychiatric inpatient hospitals in California.
  • Evaluation of test results, including false positives, and participant acceptability.

Main Results:

  • Over 471,000 antigen tests were administered to healthcare personnel.
  • A low false-positive rate of 0.0036% was observed (449 positives detected).
  • High levels of acceptability were reported among healthcare personnel.

Conclusions:

  • Daily antigen testing is a feasible and accurate strategy for healthcare personnel.
  • Antigen tests exhibit low false-positive rates and high positive predictive value.
  • This approach holds significant public health implications for reducing COVID-19 transmission.
