Abstract

Methods, systems and computer program products are used in monitoring patients, staff, and assets at a facility, initiating a response to prevent or mitigate harm, and assess and ensure overall quality and performance, and refine individual patient profiles. A plurality of sensors throughout the facility provides multiple data streams relating to the locations of patients relative to caregivers. A computer system analyzes the data stream and determines the location and/or movements of the patients relative to the caregivers. Patient profiles are periodically refined by means of an information feedback loop in order to more accurately predict (actionable) events, provide adequate care and ensure a desired level of patient wellness. From the analyzed data, staff-to-patient contact times and staff-to-patient ratios are determined. When abnormalities in staff-to-patient contact times and/or staff-to-patient ratios are detected, facility staff can be notified.
