This definition says that flow is the movement of patients between departments, staff groups or organisations as part of a patient's care pathway. So I guess it's a wider term, and a part of the patient journey/pathway (betegút in hungarian).
http://hun.proz.com/kudoz/hungarian_to_english/medical:_heal...In this case, patients are only visiting their general practioner, so I would use this definition here:
patient turnover: the number of patients seen per hour of consultation time
Salaried and fee-for-service general practitioners: is there a difference in patient turnover?
