AK Regional clearly states they weren't anticipating the amount of patients seeking care for multiple health issues.

Does primary care take handle sore throats? Of course, but they also handle patients needing annuals exams, sports physicals, and patients with several co-morbidities. 

A single provider clinic seeing 30 patients a day for sore throats and headaches? That is clearly Urgent Care.  Unless they truly believe it's feasible for a MD to do an exam, pap smear, answer all questions, and decide whether to stick with medications someone has been on for years or to prescribe different ones in 20mins.
