There's a software called Epic which is used by virtually all large healthcare centers, and while most know it as a database system to store patient history and health records (problems and conditions they've been diagnosed for, lab work results, medicine they're currently taking or have taken in the past), it also has a little tab where a healthcare worker can put in some keywords, e.g. the symptoms a patient has, and Epic guidelines gives the health-provider an action plan for that patient, as well as guiding them with differential diagnoses for non-simple issues.
Of course for common ailments a nurse practitioner knows as much as a primary care physician anyway and their treatment plans wouldn't differ, but the thing is a physician basically effectively will also only follow one script that the healthcare/insurance system in-place allows for, that Epic will spit out also.
In the same way some of us see the task of building a CRUD app as something fairly unremarkable (owing to existing frameworks, existing 'best practices' etc), a physician's day-to-day work is really not challenging, and a "people-person" non-physician equipped with Epic software could arguably work to deliver equal or if not better healthcare outcomes.
