As someone who works in healthcare (formerly at the bedside), and who's partner is a current ED nurse, this infuriates me. Department budgets are related to patient satisfaction scores, the EDs generally tend to have low scores because, yes, sorry you've been here for 3 hours, but we had 4 other patients come in (and HIPPA prevents me from telling you that they were level 1 gunshot wounds) and we can't tend to your constipation right at this second. If someone actually were to check Yelp for wait times and then have to wait longer...scores go even lower, reimbursements decrease, staff have higher patient ratios, lather, rinse, repeat.
I assure you, I have seen many, MANY patients complain and file greivances with the Department of Health, Joint Commission, etc, that their toothache, or even general wellness physical, should take prescedence over cardiac arrests. This is in a top 10 hospital in the United States, and we generally score above average with patient satsifaction. The public has no clue and this is not helping.
