A computer-based system and method improves the efficiency (quality and/or cost) of healthcare services provided to a patient by modeling an epoch of care (EOC) of the patient and by using the epoch of care model to assist in the provision of healthcare services to the patient, such as by generating predictions of healthcare outcomes for the patient and by making recommendations for actions to be taken in connection with the provision of healthcare services to the patient. An epoch of care of a patient may include all services (e.g., treatments, diagnoses, prognoses, tests, tasks, communications, education), products (e.g., medications, medical equipment, implants), and outcomes (e.g., readmissions, morbidities, patient satisfaction, symptoms) that are related to a particular medical condition or complaint of the patient over a period of time. Embodiments of the present invention may model multiple epochs of care for the same patient and may model epochs of care for multiple patients. Predictions and recommendations may be made based on the epoch of care data (including data relating to tests, treatments, and appointments spanning a wide range of times), possibly in addition to external data (e.g., contextual data, sensor data, medical history data) outside of the epoch of care.
