Validated Tools to Measure Costs for Patients: A Systematic Review

Abstract

Background

Increasing healthcare expenditures is a major concern to insurers and governments, but also to patients who must pay a greater proportion of their healthcare costs. The objective of this study was to identify validated tools for measuring the costs of a health condition for patients as well as the different elements to be considered when measuring costs from the patient’s perspective.

Methods

A systematic literature review was conducted from 1984 to December 2020. The search strategy was applied to seven different databases that had been identified prior as pertinent sources. Two authors independently extracted and compiled data. In case of disagreement, arbitration by two other researchers was conducted. The methodological quality of the included articles was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist.

Results

Among the 679 retrieved articles, nine met the inclusion criteria. The types of costs evaluated in these studies included direct costs for patients as well as for caregivers, indirect costs, and intangible costs. The development and validation processes used in these articles included a literature search, a discussion with the involved stakeholders, the development of an initial questionnaire, the testing of the questionnaire on a sample of patients, and a critical review. Regarding the psychometric properties of the tool, only five studies tested the reliability and validity of the instrument.

Conclusions

There are very few validated tools available to measure the different health-related costs from a patient perspective. Further research is needed to develop and validate a versatile and generalizable tool using a rigorous methodological process.
