Consults are one of the few actions on a computer-based case simulation that can earn you credit, waste your time, or actively cost you points depending entirely on when you place them. The USMLE states plainly that requesting the right consultation can contribute to your score — and also that in some cases you are expected to act before the consultant arrives, while in others the consult only helps if you have gathered enough information first.
That is a narrow target. This guide gives you a rule for timing, a reference list of who to call for the presentations that actually show up, and the orders to keep placing while you wait. For how consults fit into the broader grading picture, see how CCS scoring actually works.
The one rule: a consult is never your intervention
Calling cardiology is not treating a myocardial infarction. Calling surgery is not resuscitating a patient. The simulation scores what you do, and the consultant's arrival does not retroactively credit the aspirin you failed to order.
So before any consult, ask yourself: is there anything on this pathway I can order myself right now? If yes, order it first. The consult goes in alongside your own management, not instead of it.
The flip side is equally true. Do not sit on a case you cannot finish. If the definitive treatment is a procedure you cannot perform — catheterization, operative repair, endoscopy, dialysis, delivery — the consult is part of correct management and delaying it is a sequencing error.
When to call
Three triggers should put your hand on the consult order:
• The next correct step is a procedure outside your scope. You have made the diagnosis and the treatment requires a specialist's hands.
• The diagnosis is time-critical and specialist involvement is part of the standard pathway. Stroke, dissection, septic joint, incarcerated hernia. Here you call early, often before confirmatory imaging returns, and you keep managing in parallel.
• The disposition requires it. Some admissions are specialty admissions. Some discharges require specialty follow-up to be safe.
What does not warrant a consult: anything you can order from the database yourself. Transferring the patient to the intensive care unit is a location order, not a consult. Starting a heparin drip, ordering a diet, placing a Foley, giving analgesia — all yours.
Who to call: a working reference
• STEMI — Cardiology, stat, plus cardiac catheterization. Do not wait for troponin; the EKG is the diagnosis. Your own orders: aspirin, anticoagulation, antiplatelet loading, beta-blocker, statin, monitor.
• Aortic dissection — Cardiothoracic surgery, stat. Your own orders: blood pressure and heart rate control with an IV agent, imaging, intensive care transfer. Withhold anticoagulation and thrombolytics.
• Acute ischemic stroke — Neurology, stat. Your own orders: imaging, stroke scale, NPO, glucose check, blood pressure parameters, telemetry.
• Intracranial hemorrhage or posterior fossa swelling — Neurosurgery. Reverse anticoagulation yourself and control blood pressure while you wait.
• Upper or lower gastrointestinal bleeding — Gastroenterology for endoscopy. Your own orders: two large-bore IVs, type and crossmatch, fluids, transfusion, proton pump inhibitor drip, correct coagulopathy.
• Appendicitis, bowel obstruction, perforation, incarcerated hernia, necrotizing soft tissue infection — General surgery, early. Your own orders: NPO, IV fluids, antibiotics, analgesia, nasogastric tube for obstruction, pre-operative labs.
• Septic arthritis — Orthopedics for washout. Arthrocentesis and antibiotics are yours — but send the fluid before antibiotics where the patient's stability allows.
• Ectopic pregnancy, obstetric emergency, fetal distress — Obstetrics, stat. Your own orders: quantitative beta-hCG, type and screen, Rh status, ultrasound, fluids, blood.
• Airway failure or refractory respiratory failure — Anesthesia or critical care. Position, oxygenate, and prepare for intubation rather than waiting passively.
• Acute kidney injury needing dialysis — Nephrology. Treat the life-threatening hyperkalemia yourself first.
• Serious ingestion or overdose — Poison control or toxicology. Your own orders: decontamination where indicated, the specific antidote, monitoring.
• Vision-threatening eye complaint — Ophthalmology, same visit. Acute angle closure, retinal detachment, and orbital cellulitis do not wait for clinic.
• Suspected abuse or neglect, unsafe discharge, substance use disorder — Social work, and child protective services reporting where mandated. These are real point-earning actions in the right case, not filler.
• Suicidal or homicidal ideation — Psychiatry, with appropriate supervision and safety orders in place meanwhile.
What to do while you wait
The most common error after a correct consult is going idle. Placing the consult and advancing the clock four hours with nothing else pending is wasted simulated time, and the patient may deteriorate in the gap.
Keep working:
• Continue or escalate monitoring — vitals, telemetry, pulse oximetry, intake and output
• Keep the patient NPO if a procedure is coming
• Order the pre-procedure package: type and screen or crossmatch, coagulation studies, platelet count, informed consent
• Maintain fluids, antibiotics, and analgesia
• Reassess with an interval history and focused physical exam
• Advance the clock in small increments and recheck, rather than making one long jump
• Adjust treatment when results return — do not let a pending consult freeze your management

Consults that cost you points
• Consulting instead of treating. The single most expensive pattern. A consult placed in lieu of aspirin, antibiotics, or fluids does not substitute for them.
• Consulting with no data. Calling gastroenterology before you have a hemoglobin, or neurology before you have examined the patient, is premature. Gather the information that makes the consult actionable.
• Shotgunning specialties. Ordering five consults to cover yourself reads as diagnostic uncertainty. Unnecessary actions are not scored neutrally.
• Consulting for something you can order. Physical therapy, dietary counseling, smoking cessation counseling, and most imaging are direct orders.
• Forgetting the consult entirely in a procedural case. A perfectly managed appendicitis that never reaches a surgeon is an incomplete case.
Put it in your opening routine
Add one line to the scratch-paper checklist you write at the start of the section: "Does this case end in a procedure?" Ask it as soon as you have a working diagnosis. If the answer is yes, the consult goes in on that same pass as your treatment orders — not after the next clock advance.
Drill this the way you drill order sets. Run full cases on CCS cases, and check your consult timing against the case's own management arc rather than against how confident you felt.
