Performing risk management in healthcare facilities is particularly difficult due to the highly dynamic, complex, and multi-disciplinary nature of healthcare processes like the Medication Use Process (MUP). Risk-aware Business Process Management (R-BPM) is a promising approach to obtain a better understanding of such processes by identifying and analyzing corresponding risks. However, not all R-BPM approaches perform well in capturing the complexity of clinical processes. In this work, we introduce a new R-BPM framework called BPRIM that allows the identification and the analysis of medication error risks related to the complex medication use process. BPRIM is implemented using the ADOxx meta-modelling platform and then tested in a real case study. The tool is specific to the case study, but the framework can be used also in other healthcare processes.
