When you ask how much time doctors 'have' to spend with each patient, I assume you are using have as in 'how much time do they possess' and not 'are required to spend'. Assuming you are using the former (mainly because there does not seem to be a mandated minimum), doctors have as much time as they want to spend with each patient. The problem is that it's less profitable to spend more than a few minutes, and it's even more profitable to pass off the responsibility of seeing patients to those that lack a doctor's credential (who earn less). The tight deadline you refer to is entirely self-imposed due to profit models.
