Scheduling Group Care in Routine Perinatal Care: Identifying Implementation Modifications Across Belgium, Kosovo, and the UK

Background: Group Care (GC) is an antenatal/postnatal care model comprised of a stable group of pregnant people or parent–child dyads receiving care in two-hour group sessions that combine clinical care with interactive discussion and learning. Integrating GC into healthcare systems organised for individual care poses challenges at both site and system levels. This study identified scheduling-related modifications across contexts to understand modification processes. Methods: We used an explanatory sequential design with mixed qualitative methods across seven GC implementation sites in Belgium, Kosovo, and the United Kingdom. A qualitative survey based on the Framework for Reporting Adaptations and Modifications to Evidence-based interventions (FRAME) was completed at each site by multiple stakeholders. Subsequently, in-depth interviews were conducted to further explore modification processes and examine whether changes were sustained or discontinued up to three years post-implementation initiation. Results: Two modifications were identified across countries: (1) combining GC sessions with individual consultations, and (2) integrating GC into digital booking and medical record systems. Guided by FRAME, we identified similarities and differences in the goals, drivers, and impact of these modifications. The dominant one-to-one antenatal care model strongly influenced modifications, making it more difficult to implement GC as a stand-alone model in obstetrician-led systems (Belgium and Kosovo) compared to a midwifery-led system (UK). In both contexts, the dominant model negatively influenced the perceived value of GC, with GC sessions viewed only as education and individual consultations seen as the actual care. Integration in the booking system appeared essential for payment and scheduling arrangements. Conclusions: Integrating GC scheduling into existing care pathways is challenging in systems where one-to-one care is the predominant model. Sustainable integration of GC requires early coordination and shared ownership across areas, including clinical, administrative, and IT.
