Abstract In Germany, early neurological rehabilitation (ENR) acts as a link between acute inpatient care and rehabilitation, aiming to restore patients’ ability to rehabilitate amid their complex clinical conditions. Interprofessional cooperation (IPC) is crucial for harmonized treatment due to patients’ vulnerability. An interprofessional team comprising medical, nursing, and various therapy professionals is essential for this purpose. To explore the meaning of organizational culture and structure to IPC, 15 group discussions in 5 clinics were conducted with n = 76 participants. 1. Weekly team meetings are used to coordinate treatment goals and outcomes, but their implementation varies from clinic to clinic. Two types of meetings were identified: those that focus primarily on billing compliance and others that address patients’ long-term perspectives. However, both require additional social service involvement and are not sufficient to adequately address daily tasks, requiring additional IPC coordination. Some clinics have therefore introduced daily meetings to improve the coordination of IPC tasks. 2. Therapy planning and therapist assignment shape IPC and task fulfillment. Three therapy planning methods were observed: centralized, block-based, and flexible, each with different therapist allocation strategies. Centralized planning with flexible allocation leads to appointment pressure and interprofessional communication challenges. Block therapy reduces therapist turnover and promotes better interprofessional coordination in patient care. Flexible therapy planning is conducted through daily interprofessional meetings with shared task allocation and planning leads to a shared understanding. Initial analysis underscores the meaning of organizational structure on interprofessional task fulfillment in ENR, emphasizing the importance of enhancing different cooperation formats which can balance stability and flexibility and integrate social services effectively in patientcare. Key messages • Morning interprofessional meetings on the ward facilitate flexible responses to daily changes in patients’ health conditions and promote interprofessional collaboration. • The consideration of occupational group-specific processes in ward organization is a necessary structural prerequisite for successful interprofessional collaboration.
