COVID-19: a simple statistical model for predicting intensive care unit load in exponential phases of the disease [PDF]

open access: yesScientific Reports, 2021
AbstractOne major bottleneck in the ongoing COVID-19 pandemic is the limited number of critical care beds. Due to the dynamic development of infections and the time lag between when patients are infected and when a proportion of them enters an intensive care unit (ICU), the need for future intensive care can easily be underestimated.
