## Abstract

Systems, methods, and computer-executable instructions for identifying a convergence of objects includes receiving, at a device, a first beacon from a beacon transmitter located within a first location. A first location is identified based on the first beacon. A second beacon is received that is transmitted from a wearable worn by a patient. The patient associated with the second beacon is identified. A convergence time and a previous convergence time of the patient and device are determined. An out of compliance event based on the current convergence time and the previous convergence time is determined. An alert is generated based on the out of compliance event. The alert includes the first location.
