I'm a new emergency medicine resident and I'm working on refining my approach to chest pain evaluation, particularly for low to intermediate-risk patients. The guidelines are clear for obvious STEMIs, but I find the decision-making around admissions for observation versus discharge with follow-up more challenging. For more experienced clinicians, what specific elements of the history, exam, or point-of-care testing do you find most discriminatory in ruling out serious pathology in an otherwise well-appearing patient? How do you effectively communicate risk and the rationale for your disposition to patients who are anxious but have a negative initial workup? I'm also interested in how you utilize shared decision-making in these ambiguous cases.
Here's a practical framework I use in busy EDs for low- to intermediate-risk chest pain. Start with rapid rule-out of ACS: 12-lead ECG, then high-sensitivity troponin using a 0/1‑hour or 0/3‑hour algorithm where available. Use a quick HEART score (History, ECG, Age, Risk factors, Troponin) to triage risk: 0–3 low, 4–6 intermediate, 7–10 high. If HEART is 0–3 and both hs‑cTn values are below thresholds and the patient is hemodynamically stable with no dynamic ECG changes, discharge with robust return precautions and a planned outpatient follow‑up within 24–72 hours. If HEART is 4–6, move to an observation unit for serial troponins and watching for evolving symptoms; consider a stress test or coronary CT as guided by your local protocols and patient risk. If HEART is 7–10, admit or obtain rapid cardiology input for an in‑hospital rule‑out pathway.
In addition, don’t forget non‑ACS causes: pulmonary, GI, musculoskeletal, aortic disease, pulmonary embolism, etc. Use focused bedside ultrasound if available to quickly assess LV function, pericardial effusion, or aortic root dilation as an adjunct to the history and exam.
Disposition talks with anxious patients who have negative initial results should be transparent: acknowledge the tests don’t guarantee safety tomorrow, outline the plan (observation vs safe discharge with close follow‑up), and provide explicit return precautions. Shared decision‑making works best when you present options with their tradeoffs and invite the patient’s values into the plan.
If you’d like, I can share a concise, fill‑in 1‑page protocol (risk thresholds, test timing, and a patient‑facing script) you can adapt to your ED.
A quick note on communication: a simple script goes a long way. “Your initial tests are reassuring, but they don’t completely rule out a problem that could develop in the next 24–72 hours. Our plan is to either observe for a few hours with serial tests or discharge with a strict follow‑up plan today. Which do you feel most comfortable with?” This frames risk candidly and respects patient input.
If you want a ready-to-use SDM approach, you can offer two paths: 1) short stay in observation with planned re‑evaluation and possible stress testing if symptoms recur, 2) discharge with a scheduled outpatient check, home BP monitoring if indicated, and 24–72‑hour follow‑up. Have a brief decision aid describing potential risks and benefits and a checklist of red flags to watch for.
For documentation and workflow, set up a simple 2–3 hour observation window, a standardized order set for serial hs‑cTn, ECGs, a basic imaging pathway, and a nurse/PA‑led follow‑up check in. Track metrics like rate of discharge after low-risk evaluations, 30‑day return visits for chest pain, and any missed ACS events to monitor safety and improve the pathway.
