This study aimed to explore the perception of an underutilised collaborative information system through qualitative research, utilizing semi-structured, in-depth interviews with independent midwives and physician. PROSPERO, is a collaborative information system designed to bridge the communication gap between community-based healthcare workers and hospital-based care teams for parturients in Lyon, France. Through 27 semi-structured in-depth interviews with midwives, obstetricians, and general practitioners, we identified key themes related to the system’s adoption: implementation challenges, utilisation barriers, interprofessional dynamics, and hidden variables affecting system use. Participants recognised the potential of PROSPERO to improve information sharing and care coordination but expressed concerns about the system’s integration into existing workflows, time constraints, and the need for adequate training and technical support. Interprofessional dynamics revealed differing perspectives between hospital and independent practitioners, emphasising the importance of trust-building and professional recognition. Hidden variables, such as hierarchical influences and confidentiality concerns, further complicated the system’s adoption. Despite the consensus on the benefits of a collaborative information system, its implementation was hindered by mistrust between healthcare workers (i.e. between independent practitioners and hospital staff). Our findings suggest that fostering trust and addressing the identified barriers are crucial steps towards successful system implementation. The study contributes to understanding the complex interplay of factors influencing the adoption of collaborative healthcare technologies and highlights the need for strategies that support effective interprofessional collaboration and communication.ClinicalTrials ID NCT02593292.
