Toward the Implementation of a Value Framework for Diagnostic Technologies: Operationalization, Piloting, and Validation in Latin America

Objectives: In 2020, a group of 30 stakeholders from Latin America established 15 criteria for a diagnostic technologies value framework (D-VF) to help assess and inform decisions on diagnostic technologies. This article aims to present the operationalization, piloting, and initial validation of the framework for its implementation. Methods: This work was carried out collaboratively with a variety of stakeholders. Three sequential phases were undertaken: (1) operationalization of the D-VF through a literature search for conceptual definitions and assessment tools, (2) piloting of the D-VF through a rapid health technology assessment document applying the methodology of the framework, and (3) a face validation process conducted through a virtual workshop, where usefulness and implementation aspects of the framework were assessed. Results: The operationalization of the framework was conducted, and a methodological user guide was published. The D-VF criteria were applied in a health technology assessment document on human papilloma virus testing in cervical cancer screening. Also, an open-access training program was developed. Stakeholders agreed on the usefulness of the D-VF for assessment and decision-making stages of diagnostic technologies. However, they highlighted the need to improve technical capacities and the potential for added complexity when applying a D-VF with many criteria. The absence of an established value framework for diagnostic technologies in Latin America and the potential for strengthening technical capacities made the project valuable to those involved. Conclusions: The diagnostic technologies value framework was shown to be fit for implementation in real-life decisionmaking settings after the operationalization, piloting, and initial validation phases. Further experiences are important to support its implementation.
