Objective: To explore the association between patient volume in intensive care units (ICUs) and risk-adjusted mortality.Background: Large multi-speciality ICUs are emerging in response to increasing demand for criticalcare. Consolidation of resources through regionalisation of services aims to contain costs and optimise demand management and operational synergies. Higher patient volumes in ICU have been associatedwith improved outcomes. Limited evidence exists, however, to suggest an optimal volume of patients interms of risk-adjusted mortality.
