Safety Analysis of a Remote Patient Monitoring System with a Guideline Based Decision Support

Home Telehealth systems are used to help in the management of chronic conditions by patients themselves. Effective safety analysis tools are needed to ensure reliability and safety of these high risk systems. We hereby explain how Hierarchically-Performed Hazard Origin and Propagation Studies (HiP-HOPS) can be used to analyse the workflow within a Home Telemonitoring system. The results of using HiP-HOPS include the root causes of hazardous system failures that may put patients' lives at risk. Initial study of this approach shows that it has the potential to improve the safety of Telehealth systems and clinical workflows in general.
