Scribing puts you in one venue with one physician. If it is emergency services, then you do get a good idea of what an emergency medicine doc does all day and the environment and it wouldn't make sense to shadow one in addition but keep in mind that outpatient clinical settings and surgical inpatient, medical inpatient, etc, etc also exist and it couldn't hurt to arrange to shadow docs who shuttle between outpatient & OR or outpatient and L&D, etc.
