Although the researchers said they accounted for patient age I still wonder about care of a majors versus sergeant majors when the doctor is a captain. In that case the doctor out ranks the sergeant major but the sergeant major is almost always older than the other two and has positional authority the other two do not. I also wonder how much intimidation is a factor. A captain doctor will not tell a colonel patient to stay on track or cut off any irrelevant conversation even when busy.
