Objective:
Determining the Pugh multicriteria method's effectiveness as a selection tool when acquiring new technology.
Materials And Methods:
The state of the art regarding multicriteria method use was studied; the Datum or Pugh method was selected. The size of the sample of experts participating in the trial was calculated and characterised; a data sample of 23 experts was thus obtained. Electrocardiography technology was selected by using the selected decision-making method; 5 models from different providers were used.
Results:
46 tests were conducted. The model labelled '3' was selected as referent in most cases, whilst the model labelled '5' was selected as being the best option in most cases.
Conclusions:
The Pugh method was effective as a method for decision-making when selecting biomedical technologies as the same model was always selected by the experts as being the best option in 87% of the tests applied.
