Usesofcostingtools

• Provideinformationonthecostofscalingupandsustaininghealthprogramsatdifferentlevelsofthehealthsystem(andevenforglobalprograms)• Aimtoinformdecisionmakingandprogrammingtoachievespecificgoals(i.e.sustainabledevelopmentgoals)• Helpevaluateprogresstowardshealthtargets,egMillenniumdevelopmentgoals:17healthgoalstobemetoverthenext15years.
