Key Points
Question: What is the burden of critical illness in hospitals in different global settings, and where are
critically ill patients being cared for?
Findings: Among 3652 hospitalized patients in countries of different socio-economic levels (Malawi,
Sri Lanka, and Sweden) we found a point-prevalence of critical illness of 12.0% (95% CI, 11.0-13.1),
with a hospital mortality of 18.7% (95% CI, 15.3-22.6). The odds ratio of death of critically ill
compared to non-critically ill patients was 7.5 (95% CI, 5.4-10.2). Of the critically ill patients 3.9 %
(95% CI, 2.4-6.1) were cared for in Intensive Care Units (ICUs).
Meaning: Critical illness is common in hospitals and has a high mortality. Ensuring that feasible
critical care interventions are implemented throughout hospitals including in general wards where
more than nine in ten critically ill patients are cared for, has potential to improve outcomes across all
medical specialties.
