Subpopulation Process Comparison and Bottleneck Analysis: A Case Study of Frozen Shoulder

Frozen shoulder is a condition that limits shoulder movement and causes pain and discomfort. Although there are many treatment options for frozen shoulder, it is not known how these care paths differ among patient groups and whether there are any bottlenecks. This research uses the Process Mining Project Methodology in Healthcare (PMMHC) and the MIMIC-IV dataset to find the differences in the care paths among different age groups and gender. A seven-step model for bottleneck analysis and resolution was also created. The model has found that there are bottlenecks present in the general procedures followed and medications taken (i.e., continuous infusions and intermittent administrations) during the patients’ ICU stays. A limitation of this study is that it has not been evaluated by medical experts in this field so a detailed analysis by them can be a future step.
