Abstract

A system and associated method for automatically controlling a hospital equipment of in-patient care environment is performed by a module coupled to a classification database, an Inference Engine (IE), a Truth Maintenance System (TMS), and the hospital equipment. Upon admitting a patient, a patient record related to the patient is created and events for the patient are recorded. Based on inference rules of the IE, inferred event data is generated and subsequently control data to manipulate the hospital equipment is generated. Pursuant to new event affecting truth of the inferred event data, the inferred event data may be renewed and new control data based on the renewed inferred event data is created to ensure that the control data is based on the latest event related to the patient.
