A study in the Netherlands examined interprofessional collaboration among healthcare, social care, and public sector professionals addressing problematic drinking. Researchers conducted semi-structured interviews with 22 professionals to gather insights on their experiences and perceptions. Findings revealed that professionals viewed their roles in collaboration as minimalists, brokers, or skilled networkers, influenced by their job functions and perceptions of their responsibilities. Key factors for successful collaboration included accessibility, clear role definitions, and effective leadership. However, challenges such as regional, financial, and professional boundaries hindered collaboration. Participants involved in regional collaboration structures found them beneficial, while those on the outside saw them as barriers to information exchange. The study concluded that enhancing interprofessional collaboration could improve the implementation of interventions targeting problematic drinking. It recommended that organizations appoint network-oriented professionals as brokers to bridge gaps between internal and external entities. Additionally, flexible scheduling for staff could help professionals engage in broader tasks, fostering collaboration and early detection of problematic drinking. Future research should focus on developing expertise within teams and incorporating perspectives from at-risk populations into collaborative structures.
