A rapid nucleic acid amplification test (NAAT) for COVID-19 offers quick results for healthcare personnel. This rapid testing strategy enables faster return to work for uninfected employees, reducing lost work shifts.
Area of Science:
- Infectious Diseases
- Diagnostic Assays
- Occupational Health
Background:
- Healthcare personnel (HCP) with COVID-19 symptoms typically undergo SARS-CoV-2 testing in clinical laboratories.
- Results from traditional laboratory-based assays often have a turnaround time of 24 hours or more.
- Delayed results can lead to prolonged absence from work for HCP.
Purpose of the Study:
- To evaluate the effectiveness of a rapid nucleic acid amplification test (NAAT) for SARS-CoV-2 detection at the point of care for HCP.
- To assess the diagnostic accuracy and impact of a rapid NAAT strategy on work-related outcomes.
Main Methods:
- An observational study was conducted over 16 weeks, comparing a rapid NAAT performed at the point of contact with a standard NAAT assay from a clinical laboratory.
- 577 paired rapid and routine NAAT results were analyzed.
- Diagnostic accuracy metrics, including positive and negative predictive values, were calculated.
Main Results:
- The rapid NAAT demonstrated a positive predictive value of 90.0% and a negative predictive value of 95.2%.
- The implementation of the rapid test strategy resulted in an estimated 160 to 184 avoided lost work shifts over a 4-month period.
- This indicates a significant reduction in workdays lost due to symptom-related absence.
Conclusions:
- A rapid NAAT-based testing strategy is effective for the timely and safe clearance of symptomatic HCP.
- This approach facilitates an earlier return to work for employees confirmed to be uninfected with SARS-CoV-2.
- The rapid testing improves operational efficiency in healthcare settings by minimizing disruptions caused by staff absences.
