Changes to Step 3 examination in 2013
Posted: November 28, 2012
As previously announced, changes to the USMLE Step 3 examination are scheduled to take place no earlier than 2014. The redesigned examination will include assessment of "a comprehensive knowledge of both foundational science and clinical medicine," as well as "a demonstration of evidence-based medicine and quantitative reasoning skills important to patient care and to life-long learning."
Over the next few years, Step 3 examinees will see a gradual increase in test items that assess knowledge of foundational science. To give examinees a sense for what such an item might look like, an example of a 2-item set is provided below. The second item in the set is an example of how foundational science might be assessed in Step 3.
Example Step 3 item set:
A 74-year-old man comes to the ED with a 2-week history of nosebleeds with associated nausea. He says the blood drips down his throat. He denies recent trauma. Medical history includes hypertension and a stroke 2 years ago. Medications: enteric-coated 81-mg aspirin, simvastatin, and losartan. BMI is 21 kg/m2. The patient is pale. Vital signs: T=36.9°C (98.4°F), P=110/min, R=18/min, and BP=115/85 mm Hg. Pulse ox =93% O2 sat. PE: dried blood around the right nostril; left nostril is clear. Muscle strength is 4/5 in the left upper extremity. Stool occult blood is positive.
| Urea nitrogen 49 mg/dL
|| Hematocrit 18%
| Creatinine 1.49 mg/dL
|| Hemoglobin 6.1 g/dL
|| WBC 13,100/mm3
|| Platelet count 212,000/mm3
|| INR 1.3
Which of the following is the priority in management?
(A) Infusion of 0.9% saline
(B) Nasal packing
(C) Referral for colonoscopy
(D) Transfusion of packed red blood cells*
The patient is admitted to the hospital and undergoes transfusion of packed red blood cells. Four hours later, the patient's bleeding recurs. Following cautery and nasal packing, the bleeding ceases. Twelve hours later, the patient develops headache, vomiting, and muscle weakness. He is disoriented and delirious. He appears flushed and uncomfortable. Vital signs: T=38.3°C (100.9°F), P=110/min, R=26/min, and BP=92/60 mm Hg. Physical examination discloses nonpurulent conjunctivitis and a diffuse, erythematous maculopapular rash over the trunk and both lower extremities.
Which of the following is the most likely pathophysiologic mechanism of this patient's current condition?
(A) Exotoxin-mediated T-cell activation*
(B) Interleukin-mediated inhibition of CD 4+ T-lymphocytes
(C) Lipopolysaccharide-induced cytokine production
(D) Sphingosine kinase activation in inflammatory cells

In 2012, new item formats that assess an examinee's ability to appropriately interpret information presented both in the form of a research abstract and a pharmaceutical advertisement were introduced into the Step 3 examination. More information about these item formats is provided in the Comprehensive Review of USMLE updates.
In 2013, Step 3 examinees will see an increase in the number of research abstract and pharmaceutical advertisement questions.

Expanded Version of USMLE Content Outline
Posted: April 06, 2015
An expanded version of the USMLE Content Outline, which provides a common organization of content across all USMLE examinations, is now available.
The expanded version provides additional detail about subcategories of the 18 sections of the content outline. It is important to note that the USMLE Content Outline is not intended as a curriculum development or study guide. It provides a flexible organization of content for test construction that can readily accommodate new topics, emerging content domains, and shifts in emphasis. The categorizations and content coverage are subject to change.
While the USMLE Content Outline is common to all exams, each exam continues to have its own test specifications. Each exam emphasizes certain parts of the outline, and no single examination will include questions on all topics in the outline.
Additional information about the organization of the USMLE examinations is provided in the USMLE Physician Tasks/Competencies, a publication that provides a common organization of competencies and tasks assessed in USMLE examinations. Also, information concerning content specifications for each Step examination is available:
