You need to run the ER like a McDonalds. Here is what I do:
1) Review the vital signs and chief complaint. From this alone 90% of the time you know what to order. Order it.
2) For the non-sick patients, I divide them into simple and complex. It's counter-intuitive, but I actually only first eyeball the complex patients, looking at them from the door, looking at their vital signs and just how they look. I put in orders for them and then go and blitz to see the simple patients who are discharged on site. I try as hard as possible not to have to go into a room more than once. By the time the work-up is back on the complex patients, I've already discharged the simple patients, so now I can go into the complex patients' rooms and even let them know their results in the same visit.
3) Sick-as-sh** patients are different. They obviously require all your attention so they don't die on you. Those I keep a very close eye on and alert nursing staff to, often moving them to more acute rooms if necessary.
4) I literally think about throughput all the time. This means coordinating with nurses (especially charge nurses) and giving them an order-of-operations. I also call radiology techs to let them know what order I want scans done in, and also, to push them to take the patients now.
5) Order less CT scans. Ask yourself: Do I already know it's going to come back negative? Then why the hell am I ordering it?
6) Never order a test unless it will change your plan.
7) Be decisive. Don't hedge all the time. Make a plan and stick to it. Don't nickle-and-dime nurses with orders. That's annoying. Also, I usually am very aggressive with pain meds on my first volley of orders. This breaks the patient's pain and gets rid of the need to constantly order piss doses of pain meds repeatedly.
8) Don't waste time with psych patients. Snow them when possible. If they are willing, then give them Ativans and Benadryls across the board. If they are being belligerent, let nursing staff try deescalation strategies. Once you get involved, it's time for one last warning to the patient and then chemical sedation time. I consistently find doctors wasting precious time negotiating with psych patients when they KNOW it's going to all end with the same end point: sedation. It's your choice whether or not to waste five hours of back-and-forth and sedating at the end of your shift, or just doing it at the front end and then not having to deal with that patient for most of your shift. Keep in mind that I am NOT saying to chemically restrain patients who don't need it. That would be unethical. But, from your clinical experience, you will know those patients who WILL end up getting sedated. If that's the case, then just do it earlier.
9) Constantly follow up with nurses to make sure orders are being done. Why aren't labs back? Were the labs sent over? Why isn't the patient in scan yet? I always stress to the patient from the very first step in their room, "We really need your urine as soon as you can give it to us." Then, I bug the nurse about it and the tech.
10) I don't care if people get annoyed that I bug them. I always do closed loop communication with nurses and techs, and I push them to get orders done.
11) Don't ask stupid medical student level questions to patients. I remember one of my attendings made fun of me during intern year when I started talking about what color the patient's sputum was. He asked me, "Was it violet fuscha or more of a lime green?" I never asked that question again.
12) Ask the pan-positive review of systems patients, "What is your worst symptom?" I also ask, "If I had a magic wand and could get rid of one symptom for you, what would it be?"
13) Procedures take a lot of time. If you have a PA or NP, try to get them to do the lac repairs. That's a huge time suck. As for US-guided peripheral IVs, once the nurses know you can do this, they will suddenly not be able to establish IVs and your time will be wasted constantly... That's at least 20 minutes of your time. I don't care what anyone says-- it's 20 minutes from decision time to completion of the task, regardless of whether or not the actual procedure is "two minutes."
14) Discharge, discharge, discharge. Refer to PCP. Only do EM, not FP.
15) Eliminate any unnecessary steps in whatever you are doing. Throughput is king. Get faster. I disagree with those who say it's ok to be slow in residency. It's not.
FINALLY, focus your time and energy on the SICK patients. If they have unstable vital signs, obsess over them. Don't delay their evaluation, treatment, ressuss, central line, etc. The ENTIRE reason you are following the above rules is so that when these sick-as-sh** patients come to your ER, you have the time to dedicate your entire self to them so that they don't die on you. I can't tell you how many times I've seen the "compassionate ER docs" -- who spend oodles of time on the non-sick patients ordering them MRIs and whatever the hell else they want -- panic and ignore the sick patients, leaving them for sign-out, not getting central lines in them, etc. Intubate, central line, etc. early in the course of their stay... and never leave those to the next guy. That's weak.
