Current medical record software is really quite horrible to use as a human.  Another physician compared it well to the model T, which functional, lacked the comforts of current vehicles.  Data entry should use more than just fingers, voice and free gesture should be optional elements.  designing a system for physicians and health care staff is unique in that this group of users has a long history of memorizing lists of information.  this could be used to design a flow through a physical topography, or tree diagram where nodes or branching points are memorized freeing the physician to move away from the screen and still enter data.
flexible sensors on the back of fingers could allow quick access to arrays of four data points.
