ABSTRACT: Introduction: People with Parkinson's disease (PwPD) experience a wide range of motor and non-motor symptoms that have a significant impact on their health and quality of life. Effective care management for PwPD involves monitoring symptoms at home, involving specialised multidisciplinary care providers and enhancing self-management skills. This study protocol describes the process evaluation within a randomised clinical trial to assess the implementation and its impact on patient health outcomes of ParkProReakt-a proactive, multidisciplinary, digitally supported care model for community-dwelling PwPD. Methods and analysis: The hybrid efficacy-implementation study will assess key implementation outcomes using the Medical Research Council framework for complex interventions alongside a randomised controlled trial. A combination of quantitative and qualitative methods will be used to assess process data from care providers and patients. The main process outcomes are fidelity, dose, feasibility and context. Context will be analysed through semistructured interviews and focus groups using the Consolidated Framework of Implementation Research. To elucidate potential facilitators and barriers to implementation and to gain deeper insights into the efficacy outcome data, quantitative and qualitative process data will be integrated at an interpretative level using mixed methods. In addition to process evaluation, potential indirect mechanisms of impact will be measured. Ethics and dissemination: Ethical approval for this study was obtained from the responsible state medical ethics committees in Hesse and Hamburg, Germany. Results will be communicated to the funding body and disseminated through scientific publications. Trial registration: This study was registered with the German Registry for Clinical Studies (DRKS)-number: DRKS00031092.
