BackgroundClinical quality registries (CQRs) can likely improve quality in healthcare and research. However, studies indicate that effective use of CQRs is hindered by lack of engagement and interest among stakeholders, as well as factors related to organisational context, registry design and data quality. To fulfil the potential of CQRs, more knowledge on stakeholders’ perceptions of the factors that will facilitate or hamper the development of CQRs is essential to the more appropriate targeting of registry implementation and the subsequent use of the data. The primary aim of this study was to examine factors that can potentially affect the development of a national CQR for interventional radiology in Norway from the perspective of stakeholders. Furthermore, we wanted to identify the intervention functions likely to enable CQR development. Only one such registry, located in Sweden, has been established. To provide a broader context for the Norwegian study, we also sought to investigate experiences with the development of this registry.MethodsA qualitative study of ten Norwegian radiologists and radiographers using focus groups was conducted, and an in-depth interview with the initiator of the Swedish registry was carried out. Questions were based on the Capability, Opportunity and Motivation for Behaviour Model and the Theoretical Domains Framework. The participants’ responses were categorised into predefined themes using a deductive process of thematic analysis.ResultsKnowledge of the rationale used in establishing a CQR, beliefs about the beneficial consequences of a registry for quality improvement and research and an opportunity to learn from a well-developed registry were perceived by the participants as factors facilitating CQR development. The study further identified a range of development barriers related to environmental and resource factors (e.g., a lack of organisational support, time) and individuallevel factors (e.g., role boundaries, resistance to change), as well as several intervention functions likely to be appropriate in targeting these barriers.ConclusionThis study provides a deeper understanding of factors that may be involved in the behaviour of stakeholders regarding the development of a CQR. The findings may assist in designing, implementing and evaluating a methodologically rigorous CQR intervention.
