Abstract

With modern wearable sensor and networking technologies improving, it is becoming possible to continuously monitor patients remotely over the Internet, while they go about their everyday lives, and call them into the hospital only when their conditions deteriorate to the point where hospital intervention is needed. Such is, for example, the case with continuous glucose monitoring of pediatric diabetes patients. We discuss two key complementary problems involved in remote patient monitoring over the Internet. The first is about which wearable sensors to activate (and when) in order to remotely estimate the patient’s health state, given that sensors are typically battery constrained; activating all sensors too frequently will simply run them out of battery sooner than normal. The second is about when to call a patient into the hospital for medical intervention, given an observed deteriorating health state and, subsequently, when to discharge the patient from the hospital as the health state improves. We design and analyze two formal stochastic optimization models capturing the tradeoffs in these two complementary problems and glean insights about such novel service operations.
