I guess it depends on what you’re familiar with. Some of the protocols are very straight forward...chest pain pending cardiologist eval and stress test result, PO challenge from persistent n/v, or copd exacerbation reeval. It shouldn’t be complicated or it would have been outright admitted. 30 patients over a whole day with an APP +/- a resident is not that bad, especially when consultants/PCPs are often rounding to help with dispos.
That being said, if you only like working in the ED then yes you won’t like it. But for the select few that enjoy it, it offers a niche within EM, regular slower paced hours and good pay.
