First patient complaint ever. Frustrated.

We cant' sit here and second guess everything that was happening cause we don't have all the details.
I'm not really sure what your question is...?

If you are asking about the triage process here's my take:
1) Regardless of where the pt signed into, doesn't mean they need to go there. Each pt is assessed by nursing based on their own merits. So he may have started out as a "walk-in" but could have been upgraded to main ER to treat
2) One of the MOST COMMON lawsuits is missed cardiac complications so ALWAYS err on the side of caution. If your ER MD doesn't like this then tough crap; just remind them why THEY practice defensive medicine!
3) I'm thinking cardiac workup for the following:
-non traumatic cp
-nearly ANY cardiac hx (esp recent surgery)
-age > 40/45
-personal/family Hx of cardiac
-other medical conditions (DIABETES = red flag!)

DO NOT let the useful ness of NTG fool you! Sometimes it may point to cardiac, other times not; EVEN when it works sometimes!
DO NOT let the duration of symptoms fool you - CP for '2 weeks' can still be coronary/anginal equivalents; are they having an ACUTE MI right now? Probably not. But do they need to be placed in a MONITORED room and a cardiac assesment done ABSOLUTELY!!!

Keep your chin up, remember you did right by the patient and that's the primary purpose!
