Background: During Taiwan’s May 2021 COVID-19 surge, hospitals expanded ICU capacity using both conventional and ward-converted (“silent”) ICUs. Methods: We retrospectively compared adults with severe COVID-19 admitted to three ICUs (two classic and one ward-based) between May and August 2021. The primary outcome was ICU mortality; secondary outcomes included ventilator-weaning success and complications. Results: Sixty-four patients were included (28 classic, 36 silent ICU). Baseline severity was comparable (median APACHE II 21 vs. 20). ICU mortality was 29% vs. 36% (risk difference 7. 5%, 95% CI -18. 6 to 33. 1). No difference was found in weaning success or complication rates. No staff infections occurred. Conclusions: Outcomes in the ward-converted silent ICU were comparable to those in classic ICUs. With appropriate infection control and staffing, silent ICUs can safely expand surge capacity.
