Table 1 Rapid antigen screening programs evaluated and compared with the baseline of RT-PCR testing of only severe symptomatic cases. Screening programs SP1, SP2, and SP3 are incremental to the baseline and include testing of severe cases
From: Economic evaluation of COVID-19 rapid antigen screening programs in the workplace
Scenarios | Target population | Status | Test (result) | Action 1 | Action 2 |
|---|---|---|---|---|---|
Baseline | General population | Severe symptomatic | RT-PCR(+) | Start isolation for 5 days | None |
Screening program | |||||
 SP1 | Workplace | Asymptomatic | RA(+) | Start isolation for 5 days | None |
 SP2 | Workplace | Asymptomatic | RA(+) | Start isolation for 5 days and follow up with an RT-PCR test on the same day of initial RA(+) | If RT-PCR+, complete 5 days of isolation, otherwise end isolation |
 SP3 | Workplace | Asymptomatic | RA(+) | Start isolation for 5 days and follow up with RA test a day after initial RA(+) | If second RA+, complete 5 days of isolation, otherwise end isolation |
