BackgroundHome-based healthcare services are facing challenges and pressures of increasing needs due to an ageing population, rising workload for an overburdened workforce, and limited financial resources. The trust model is an approach to address the challenges, by organizing the home-based healthcare services into smaller, autonomous interdisciplinary teams. The aim is to involve users and next of kin in decision-making and trusting frontline workers’ professional judgement, thus making the services more flexible and individually tailored. This study explores frontline workers’ practices and experiences of working within interdisciplinary teams according to the trust model’s goals.MethodsObservations, individual-, and focus groups interviews were conducted within home-based healthcare service in a Norwegian municipality. The participants were leaders and frontline workers at different levels of the home-based healthcare services, including registered nurses, auxiliary nurses, occupational therapists, physiotherapists, and other unskilled healthcare personnel. Data was analysed thematically.ResultsThe results are presented in terms of themes: ‘We all want the best for service users’, ‘Belonging to an interdisciplinary team’ and ‘Maintaining belonging to those with similar work tasks and responsibilities’. The results show a diversity among the participants’ experiences of working within interdisciplinary teams. It demonstrates a dilemma between creating belonging to and forming identities within the interdisciplinary team, and at the same time, the importance of maintaining belonging and identity with those in the same profession or with the same tasks and responsibilities.ConclusionThis study suggests that the frontline workers need for dual belonging seems to be underestimated within the trust model, and by acknowledging this, organisations and policymakers can create environments that support both. Which in turn can enhance the possibility to deliver flexible and individually tailored services for service users.
