ICU resources
How much do we spend on ICU services?Are our expenses growing?Are the resources becoming more expensive?
Are we spending evenly?Within countriesAcross countries
Is it enough? Or is it too much?
Are we spending wisely?How might we spend better?

ConclusionCurrent ICU resource use
Large and expensive in many countriesGrowing everywhere
Variation in provision of ICU servicesBetween countriesWithin countries
More ICU resources may or may not improve outcomes
Future pressuresMore patients, sicker patients, and higher costs(Relatively) less money, less resources, fewer people (?)Staffing likely to worsen
Consider more strategic, population-based planningStratified ‘levels’ of careRegionalization of services
