Hospital admission probability and length of stay among Covid-19 confirmed cases

The numbers of Covid-19 confirmed cases and hospital admissions have varied across the course of the pandemic in Ireland. Three broad waves can be identified; March through July, August through November, and December through February. The majority of confirmed cases and hospital admissions have been recorded since December. This briefing note examines how relationships have varied over the course of the pandemic between cases and the two main parameters affecting hospital service demand: admissions to and lengths of stay in hospital and critical care. Particular attention is paid to variations by age in distributions of admission probabilities and average length of stay across periods of the pandemic.
