Patient involvement (PI) has become a key priority to the Spanish Network of Agencies for Assessing National Health System Technologies and Performance (RedETS). As part of the national strategy to promote PI, an interest group was created in 2017 to share knowledge, develop methodologies and standardize PI processes. The aim of this work is to analyze the main activities of the Patient Interest Group 5 years after its launch and to reflect on possible needs and challenges.

Narrative description and an in-depth analysis of the main activities of the Interest Group from 2017 to the present.

The group is composed of HTA researchers from the 8 regional agencies in Spain and is supported by the Ministry of Health and the RedETS council. It currently has the participation of 26 researchers, organized into different working subgroups. The initial lines of work were the analysis of the situation, the development of procedures, and the initiation of training materials for patients on HTA. At present, the main projects are the development of metrics for evaluating the impact of patient participation, the development of procedural materials to promote methodological process standardizaton (e.g., a flowchart with the main process steps, checklists, templates), and the design and piloting of virtual training for patients in HTA. New lines include the analysis of the ethical challenges of PI and the feasibility of setting up an HTA patient registration system and a patient forum to facilitate participation. In addition, the interest group has promoted the exchange of relevant information for PI and the organization of capacity building activities.

The RedETS Patient Interest Group is encouraging the development of activities, reflection on collective experiences, and tools that facilitate PI in Spain. Among the main challenges are the need to ensure the quality and applicability of PI and to analyze the views of patients who have actively participated in HTAs.
