Exploring participants' characteristics and self-assessed readiness to conduct clinical trials in general practice : baseline analysis of the RaPHaeL practice-based research network

Background: Primary care is integral to healthcare systems extending beyond traditional illness management to include preventive care, chronic disease management, and health promotion. Practice-based research networks (PBRNs) have emerged as essential infrastructures for conducting clinical research in primary care. This study explores the establishment of the ‘Research-Practices Halle-Leipzig’ (RaPHaeL) PBRN in Germany, evaluating the characteristics and research readiness of participating practices. Methods: A cross-sectional survey (MORNING II) was conducted among all general practitioners (GPs) joining the RaPHaeL PBRN, assessing socio-demographic characteristics, practice infrastructure, and research readiness. After a descriptive analysis, we compared data with a previous study (MORNING) to examine potential differences between PBRN participants and non-participants. We developed a research readiness score (RRS) to quantify practices’ ability to perform clinical research subtasks. Results: The response rate was 97.1% and our participants were often male, involved in undergraduate education, generally interested in research or had previous research experiences. However, they differed widely in age and size, staff structure, and patient demographics of their practices. Initially, around two-thirds of the practices were not sufficiently prepared to conduct clinical trials (self-assessed feasibility of relevant subtasks). If further research and documentation tasks are required, patient recruitment estimations are lower than for patient identification and information. Conclusion: This study highlights the variability in research readiness among GP practices and shows the need for targeted training. By systematically assessing and enhancing research capabilities of participating GPs, PBRNs can facilitate high-quality clinical research in primary care to improve patient outcomes and healthcare delivery.
