Don't start an encounter with, "what brings you in?". Often the patient will respond with I don't know - (wtf) you tell me - that's why I'm here!
Reference your state of the art electronic record and how you will review their history, if you haven't already. Do this before asking about their past medical history - and that you want to hear it from them too.
Don't ask if they've had fevers. They may respond frustrated, I don't know they just took my temperature (stupid)! Ask if they've had fevers at home as far as they know.
Don't ask if they drink. Ask if they drink beer, wine or liquor... A lot of patients don't consider beer a 'drink'.
When you tap, push or prod attempting to elicit tenderness, apologize that it might hurt before doing so.
The 99th percentile heart rate for a 1.5-year-old child is 150. 160 less than 1yo and 140 for a 2yo - 3yo.
Be very very wary of discharging a patient with tachycardia.
If they clearly fit the pattern, rock it out. If they don't fit the pattern don't force it to fit and avoid anchoring bias.
Provide all the benefit of the doubt. Patients with mental illness have a higher overall mortality than those without.
If in doubt tube, tap and drain.
When overdosing on adrenaline, use combat breathing.
Talk to every patient as if you are truly on their side. Excluding psychiatric patients look warmly into everyone's eyes. Everyone's. Doesn't matter what you think or feel about them, become them for the moments that you are interacting with them. Emergency medicine really is theater in some ways. Be all in when you are on stage.
When you feel like screaming or crying because of a nasty interaction, painful error, overwhelming task saturation and the like know the shift will-eventually-end. Stay present and just keep going. Embrace that everyone, everywhere occasionally gets a bloody beat down. Some days the ED just wins and we lose. Reliably, your next shifts will be more for likable. (If this fails to occur, find a new shop.)
If your note automatically goes to the patient's primary tell the patient that you will send their doctor a personal note about their visit today.
Conclude every visit with a pause and a sincere, "do you have any other questions". Your mind will be screaming to exit the room but it will ultimately save time and energy to conclude in this manner. Doesn't matter how messy the encounter might have been, as in many things, it's all about the resolve.
