A medical informatics physician performs numerous duties within the subspecialty of medical informatics. Your responsibilities in this career may include collaborating closely with other physicians, nurses, researchers, and other clinical practitioners to design and implement a data collection process for your healthcare facility or for the field in general. By collecting as much information about health care provision at your facility as possible, you can recommend improvements to patient support services, the decision-making process at your facility, and additional decision support methods designed to improve the communication between the patient and the clinician.
