Different
types of economic evaluation
In
this next section, we will look at the five types of economic evaluation.
How we can go about comparing the interventions depends on how the outcomes
are measured. Because there are different ways of doing this, there are
different types of economic evaluation study.
1.
Cost-consequences analysis - an
analysis in which the outcomes of interventions are presented in different
ways, or as a range (profile) of outcomes impacted differently by interventions.

Example:
“The effectiveness results were as follows: The average operation
time was 20 minutes in the percutaneous dilatational tracheostomy (PDT)
group and 36 minutes in the surgical tracheostomy (ST) group. Eight
major complications were reported in the study: five (6.8%) in the PDT
group and 3 (2.2%) in the ST group. Among minor complications, the PDT
option resulted in bleeding (2.7% of patients) and desaturation/cuff
leak (1.4%) and poor position requiring tube change (1.4%). In the ST
group, only bleeding was reported (0.7%).” |
Because
of the different profile of outcomes, we can't directly compare the interventions.
