  1. Targeted admission of patients with positive test or suspect SARS-CoV-2 infection to a COVID-19 ward or other ward with infection prevention control (IPC) facilities did not change by the introduction of rapid point of care tests (Period 2: Rapid antigen detection test; Period 3: rapid RT-PCR VitaPCR) at the Emergency Department (ED). However, test-negative patients were increasingly admitted to appropriate specialized hospital wards (“Other”) during Period 2 and 3. Total number of participants in each period (N =) and in each subgroup (n =) are presented with percentage of N = and 95% confidence interval (CI)
