This dissertation systematically investigates the attitudes and preferences of health professionals regarding new models of care. It addresses four central knowledge gaps by examining health professionals' willingness to engage in health-promoting practices, their attitudes towards interprofessional collaboration and responsibility-sharing, their individual innovativeness, and their preferences concerning the design of new models of care. To this end, a large-scale cross-sectional study was conducted in 2022, based on a nationwide web-based survey among pharmacists, physicians, medical practice assistants, nurses, and physiotherapists – the five largest health professional groups in Swiss primary care. In total, 4,063 health professionals participated. The dissertation identifies a clear willingness among health professionals, particularly nonphysicians, to embrace enhanced responsibilities, health promotion activities, interprofessional collaboration, and innovation. Professionals across all groups favour collaborative, interprofessional models featuring shared decision-making processes and organisational structures such as health centres and networks, moving beyond traditional general practitioner-centred care. These findings highlight that new primary care models, informed by professionals' preferences, could address systemic challenges such as workforce shortages while enhancing the attractiveness of careers in primary care. By aligning the development of models of care with professionals' preferences, this dissertation provides empirical evidence to inform the sustainable transformation of primary care. These insights offer guidance for policymakers, educators, healthcare providers, and researchers aiming to implement sustainable primary care structures.enthesis
