Chest Pain Refusal With a Deteriorating Patient
At 14:07, a 58-year-old man tells his wife he has crushing central chest pain that started 18 minutes ago while mowing the lawn. The pain is 8/10, radiates to the left jaw and arm, and is accompanied by nausea and sweating. He has a history of a drug-eluting stent in 2019 and takes aspirin 81 mg, atorvastatin, and metoprolol daily. He is alert, speaking in full sentences, and his wife reports he looks pale. He refuses an ambulance, saying he will drive himself to the hospital eight minutes away. The wife is calling from a cell phone; she is calm but insistent that he be seen quickly. There are no known allergies. The dispatcher must decide the response level, what to tell the caller before EMS arrives, and how to handle the refusal without delaying care.
1. What dispatch determinant and response level would you assign, and why? Explain how you weigh the refusal.
Read the worked answer
This is a high-acuity medical call, not a routine transport. The key inputs are adult, central chest pain, radiation to jaw and arm, diaphoresis, nausea, age 58, and known coronary disease with a prior stent. Those features point toward a cardiac cause and a time-critical event. The appropriate response is a high-priority ALS unit, with the nearest BLS unit as needed, because ALS can monitor, obtain a 12-lead ECG, and administer medications en route.
The refusal does not downgrade the call. Dispatch priority is based on the patient's symptoms and risk, not on the caller's transportation preference. Accepting a refusal by phone would be unsafe because the patient may deteriorate before arrival. Keep the wife on the line, tell her not to let him drive, and explain that EMS can assess him at the door. If he still refuses, the refusal is managed on scene by EMS, not by the dispatcher. Document the refusal statements and keep the response active.
2. What pre-arrival instructions are appropriate, and what should you explicitly not instruct?
Read the worked answer
Appropriate instructions focus on safety and readiness. Have him sit or lie in the position of comfort, loosen tight clothing, and stay still. Tell the wife to unlock the front door, turn on outside lights, gather medication bottles, and keep the phone nearby. If he becomes unresponsive and is not breathing normally, be ready to start CPR and use an AED if available.
Do not tell him to drive himself or walk to the car. Do not advise a new aspirin dose without protocol guidance, especially because he already takes daily aspirin and may have contraindications. Do not advise nitroglycerin from someone else's prescription. Do not reassure the caller that this is 'just heartburn.' Do not hang up to call the hospital; keep the line open and update EMS if symptoms change. The reasoning is that any exertion or delay increases myocardial oxygen demand and risk of arrest.
3. The wife says, 'He's turning gray and won't answer me.' What changes?
Read the worked answer
This is a deterioration from a chest-pain call to a possible cardiac arrest. Stop discussing refusal and switch to airway, breathing, and circulation. Ask whether he is breathing normally. If he is not breathing normally, give CPR instructions immediately and direct the wife to an AED if one is nearby. Upgrade the response if your system allows, and notify responding units that the patient is now unresponsive and gray.
The reasoning is that unresponsiveness with abnormal breathing in a cardiac-risk patient is cardiac arrest until proven otherwise. Do not spend time checking a pulse by phone or asking the caller to find a blood pressure cuff. Keep the caller on the line, coach compressions, and ensure the door is unlocked for EMS. If he begins breathing normally but remains unresponsive, place him in a recovery position and continue to monitor breathing until EMS arrives.
