BackgroundAchieving access to quality healthcare services to ensure healthy lives and promote well-being for all at all ages is one of the United Nation’s Sustainable Developments Goals. In view of this goal, sustainable community healthcare services in Norway need to be urgently restructured in light of demographic changes, including an increase in the percentage of older adults in the country. National healthcare policies recommend finding new ways to organise and perform services using new technology, new methods and new solutions. The goal is to ensure greater continuity in the provision of services and softer transitions that enable service users to deal with a smaller number of people. The trust model is one such suggested organisational approach. The goal of the trust model is to involve service users and their next of kin in decisions that concern them while also trusting frontline workers’ professional judgement in assessing the need for services and adjusting them to address changes in the health of the users, thus making the services individually tailored and more flexible. This study aims to explore how organisational work structures influence the delivery of interdisciplinary home-based healthcare services.MethodsObservations, individual-, and focus groups interviews were conducted within community home-based healthcare services in a large Norwegian city with managers at different levels, nurses, occupational therapists, physiotherapists, purchaser-unit employees and other healthcare workers. Data was analysed thematically.ResultsThe results are presented in terms of themes— “Balancing on the margins: Negotiations between the time available, users’ needs, unforeseen events and administrative tasks” and “One gathered unit, but with different work structures”. The results identify organisational work structures that influence the performance of the trust model with regard to its intention of making flexible and individually tailored services available. However, these structures are different for the members of the interdisciplinary team, thus creating several paradoxes that need to be negotiated while fulfilling their daily responsibilities.ConclusionThis study suggests that it is crucial to pay attention to paradoxes and structures experienced by interdisciplinary frontline workers in home-based healthcare services, since they are unavoidable factors that need to be acknowledged when designing approaches for addressing the changes expected in community healthcare services.
