The disclosed technology is directed towards presenting a medical practitioner with information that assists the practitioner in communicating with a given patient. Baseline data describing a medical patient is obtained, such as from one or more previous visits. The baseline data can be compared with current data, e.g., sensed by patient biosensors and/or discerned from a current video of the patient during the visit. Historical and/or known healthy data can be used as baseline data. Interaction data representing an interaction (e.g., a conversation during a current visit) between the medical practitioner and the medical patient is determined. Based on the baseline data and the interaction data, during the interaction between the medical practitioner and the medical patient the medical practitioner can be presented with coaching data to assist the medical practitioner in communicating with the patient.
