The Transferability of Economic Evaluations: Testing the Model of Welte

Abstract

The application of Welte's model does influence cost and effects estimates when transferring economic data between countries. However, more cases should be subjected to the Welte transferability model before a final conclusion can be drawn.

“…Thirty-nine percent of respondents indicated that there were no guidelines for conducting HTA in their countries, but 11% did not answer this question. Sixty-two percent said they used HTA reports that had been produced in other jurisdictions to help in their decisions, which agrees with findings from other authors (15)(16)(17)(18)(19)(20)(21). HTA work produced in different contexts is usually adapted to the local situation in order to be used in the decision-making process.…”

How to prepare a systematic review of economic evaluations for informing evidence-based healthcare decisions: data extraction, risk of bias, and transferability (part 3/3)

“…Looking at transferability, several checklists have been identified, of which the Welte checklist [33] has raised the most attention, likely due to the relative ease of application. In addition, the Welte checklist has been thoroughly examined [30], and the checklist of Drummond et al [36] is based on the work of Welte et al [33]. If one is particularly interested in assessing the applicability of HTAs to resource allocation decisions, the Grutters checklist [37] might be a suitable option (see online supplementary material II).…”

“…Transferability is referred to as the extent to which the results of a study hold true for a different population or setting [30]. For example, results derived from a study conducted in a developed country will not be representative for use in a developing country.…”

“…For example, results derived from a study conducted in a developed country will not be representative for use in a developing country. Generalizability is defined as the extent to which the results of a study can be generalized to the population from which the sample was drawn [30]. Although theoretically there is a clear difference between both concepts, they are often used interchangeably.…”

“…The checklist of Welte et al was found to be a convenient list because it has clear cutoff points and can be used for the assessment of both trial-and model-based EEs. It has been applied successfully in the past [32], and the model has been tested extensively by Knies et al [30]. The Welte checklist [33] consists of three general knockout criteria which need to be considered before proceeding to 14 specific knockout criteria (see Table 5).…”
