Multidisciplinary teams are on the rise across multiple welfare areas. The intention is to address challenges of increased specialization and fragmented services through closer collaboration between professionals in order to ensure coherency in complex client pathways. However, the existing research may not be sufficient to grasp collaboration in the less specialized welfare areas, where multidisciplinary teams increasingly emerge. This PhD will help close this knowledge gap by studying boundary work among so-called lower status professions in the Danish eldercare sector. The project will produce empirically grounded analyses of effective boundary work practices essential to coherency in complex client pathways in eldercare. The project’s main theoretical contribution will be to the boundary work literature and consist of comparative analyses of how low status professions practice boundary work in different organizational forms. Through a qualitative comparative case study design, the PhD will expand current theoretical knowledge by developing theory on the link between boundary work and organisational context, including the impact of multidisciplinary team organizing on collaboration. The project’s main empirical contribution is knowledge on how multidisciplinary teams can play a role in creating a viable eldercare sector, which delivers coherent services to complex clients through closer collaboration while succeeding in recruiting and retaining core professionals.
