Qualitative research is being increasingly integrated in heath technology assessments (HTA) within the Spanish Network of Agencies for Assessing National Health System Technologies and Performance (RedETS). Qualitative research methodological guidelines are given in RedETS HTA guidelines and the Patient Involvement Strategy. A specific methodological guideline to systematically review qualitative studies was published in 2007 and is pending its update. The impact of their implementation is unknown. The aim of this work is to analyze the techniques, impact and reporting of qualitative research (primary and secondary) in HTAs.

A manual search of the HTAs published in the last 5 years in RedETS was conducted to locate assessments that include qualitative research. To ensure a complete identification, RedETS agencies and units were consulted to provide information about the assessments that have used qualitative techniques in their development over the past 5 years. A content analysis of the selected assessments was conducted to analyze the techniques, impact and reporting of qualitative research in HTA.

In the past five years, focus groups, semi-structured interviews, evidence synthesis of observational studies including qualitative studies have been used and integrated in HTA in RedETS. Most of them have been linked to patient involvement facilitation or the inclusion of patient perspectives in HTA. Qualitative research has been used to analyze patient’s experiences and values, to elicit and select important outcome measures for patients, to research for barriers-facilitators for technology implementation and to inform evidence to decision frameworks.

Qualitative primary and secondary research is being used in HTA in Spain. It is mainly linked to patient involvement strategies both to elicit patient perspectives directly or to collect patient-based evidence. The impact of qualitative research in HTA is broad and diverse, extending from the scope of the assessments to the drafting of the recommendations.
