In this retrospective, integrative literature review, the authors explore the association between patient volume in intensive care units (ICUs) and risk-adjusted mortality.

Twenty quantitative observational studies were included. The authors conclude from the results that "patient mortality may be improved in large capacity ICUs. However, the association is not consistent across all diagnostic groups. Risk adjusted mortality is increased in low volume ICUs. There appears to be a high volume threshold at which point the risk adjusted mortality benefit is also lost suggesting a window of optimal ICU organisational performance exists between low and high volumes". The authors make recommendations for further research.
