Secure decentralized decisions to enhance coordination in consolidated hospital systems

1. IntroductionHospitals consolidation is one of the effective ways to increase long-term benefits by providing integrated health services. Integrated health services in hospitals increase the quality of the services and decrease the service costs (Dai, 2017). The improvement of information and communication technologies in recent years and the application of the electronic medical records madeRead More…

Virtual reality based hybrid simulation for functional endoscopic sinus surgery: IISE Transactions on Healthcare Systems Engineering: Vol 10, No 2

Advances in Virtual Reality (VR) technology warrants the improvement of the training system to replicate surgical procedures. The VR-based training system has proved to be useful for surgical training by decreasing operative time and increasing patient safety. For example, Functional Endoscopic Sinus Surgery (FESS) is challenging due to the confined operating space surrounded by critical structRead More…

Hybrid ordering policies for platelet inventory management under demand uncertainty: IISE Transactions on Healthcare Systems Engineering: Vol 10, No 2

Hospitals are imposed with the challenge of developing efficient blood inventory management tools due to its limited supply and uncertain demand. Besides, the short shelf-life of blood further complicates the task of its inventory administration. Since lifesaving blood is required as frequent as once in two seconds and blood donations are falling short of patient needs, hospitals maintain a higRead More…

Analyzing client behavior in a syringe exchange program: IISE Transactions on Healthcare Systems Engineering: Vol 10, No 2

Multiple syringe exchange programs serve the Chicago metropolitan area, providing support for drug users to help prevent infectious diseases. Using data from one program over a ten-year period, we study the behavior of its clients, focusing on the temporal process governing their visits to service locations and on their demographics. We construct a phase-type distribution with an affine relatioRead More…

Missing information imputation for disease-dedicated social networks with heterogeneous auxiliary data: IISE Transactions on Healthcare Systems Engineering: Vol 10, No 2

Many high impact applications suffer from missing information. For example, disease-dedicated social networks provide additional resources to glimpse into patients’ daily life related to disease management. However, due to the voluntary nature of such social networks, the information reported by patients is often incomplete, making the following data analytics tasks particularly challenging. Read More…

Network modeling and Internet of things for smart and connected health systems—a case study for smart heart health monitoring and management: IISE Transactions on Healthcare Systems Engineering: Vol 0, No 0

Heart disease is a leading cause of death in the US. Recent advances in the Internet of Things (IoT) provide a great opportunity to realize smart and connected health systems through IoT monitoring and sensor-based data analytics of cardiac disorders. However, big data arising from the large-scale IoT system pose a significant challenge for efficient and effective sensory information processingRead More…

Staffing decisions in a tele-ICU: dedicated versus flexible resources: IISE Transactions on Healthcare Systems Engineering: Vol 0, No 0

In a tele-ICU center with flexible staff scheduling, interruptions to tasks with lower priority are common, often prolonging the processing time of these tasks. Dedicated staff scheduling, however, can reduce such interruptions. While dedicated staff scheduling is generally perceived to be less efficient than flexible systems according to traditional queueing theory, the reductions in interruptRead More…
