In most other human activities there are two speeds, fast and slow. Usually, one dominates. Think firefighting versus bridge design. Healthcare spans from one extreme to the other. Think Code Blue versus diabetes care.
Primary Care was once a place where you treated things like earaches and unexplained weight loss in appointments of different length with documentation of different complexity. By doing both in the same clinic over the lifespan of patients, an aggregate picture of each patient was created and curated.
A patient with an earache used to be in and out in less than five minutes. That doesn’t happen anymore. Not that doctors and clinics wouldn’t love to work that way, but we are severely penalized for providing quick access and focused care for our well-established patients.
