Economic evaluation
Comparison of two or more alternative treatments in terms of costs and consequences
Quality adjusted life years (QALY)
Utility is quality of life and is deteremined by EQ-5D-5L health questionnaire giving a score out of 1 This is multiplied by the number of years
Cost minimisation
Assumes effectiveness is equal Intervention which achieves the desired outcome at the lowest price
Cost effectiveness
Does not make assumptions on effectiveness Beneifts usually measured in QALYs Essentially looks for best value for money but only considers costs to the NHS
Incremental cost effectiveness ratio (ICER)
Difference in treatment costs/ difference in effectivenessTied to diminishing utility of the utility gained decreasing over many repititions
Cost benefit analysis
Compares medical outcomes and expresses it in monetary terms Difficult due to the need to cost every factor Most common method of assigning value is the ‘willingness to pay’ approach ie what are those extra few years actually worth to you
