Apologies for the confusing question title. Read on and you will see what I mean.
I work for a large general hospital. We are attempting to go fully digital.
One of our biggest stumbling blocks is that clinicians sometimes need to make medical illustrations and put them in people's casenote folder. At the moment, they do this and the casenotes go to the other side of the hospital to get scanned. The paper copy is then destroyed.
This creates a tremendous amount of work and is horrendously inefficient. However, it is better than the current alternative, which is getting the clinician to scan the drawing locally. If they do this, we can't rely on them to destroy the paper copy, which is sometimes added to or notes are written on it, creating a clinically dangerous double-entry problem.
Because we're a general hospital, solutions designed for eye specialist, heart specialists and so on will not work. We need something as context-agnostic as a pencil and a piece of paper.
High-quality drawing tablets won't work, because it isn't possible to draw into our medical software. I was thinking about some kind of captive whiteboard under a visualiser, but AFAIK whiteboards are not ever used for precise drawings.
I think the answer is some kind of photograph of a drawing. They can't draw something and scan it in later; it needs to be done in the patient context: i.e., you open the patient's record and then you make the drawing.
