Zusammenfassung
Patient safety is endangered by adverse events caused by human error and system design. The reasons are diverse: missing standards; organizational deficits; communication errors; time pressure. Systems ergonomics claims to optimize work systems enabling high quality (including safety) and efficiency. A systems ergonomics management concept is proposed, which is based on: (1) an interaction model (patient-staff-machine); (2) a medical task-model; (3) a recursive hierarchical task-process-task-model; 4) a strategic treatment management model. On three systems layers a patient treatment is analysed and optimized: macro-level (clinical pathways), meso-level (treatment modules), micro-level (standard operating procedures). According to the situation (patient's status and given resources), the treatment is compiled using standardized and navigated treatment components. ABSTRACT FROM AUTHOR
