On the "Duh" front, researchers have determined that primary care physicians manage several patient problems during a single office visit.
Researchers analyzing conversations between physicians and patients more than 65 years old found that on average, six topics were discussed during the visit, as the patient and physician each brought up items of concern.
This actually seems like a low number to me. Primary care physicians are asked to do what is literally impossible. To keep an office open, based on the low reimbursement rates, you need to see something like 25 patients a day, which means 15 minute office visits.
The average patient over 65 probably has at least three chronic conditions to manage, plus preventive stuff, plus acute problems like knee pain or dizziness. Just to do the required preventive care takes something like 10 hours a day - there's research on that.
Primary physicians need to be paid more per office visit, so they can see fewer patients and take good care of the ones they see.
If this doesn't happen, we won't have any primary physicians left because they'll all quit or have heart attacks from the stress.
