USCIS Research & Evidence-Based Practice 2 — Questions and Answers
Question 1: Which organization publishes the Technical Instructions that civil surgeons must follow when conducting USCIS immigration medical exams?
- World Health Organization (WHO)
- Centers for Disease Control and Prevention (CDC) (Correct answer)
- U.S. Citizenship and Immigration Services (USCIS)
- National Institutes of Health (NIH)
Correct answer: Centers for Disease Control and Prevention (CDC)
The CDC publishes and updates the Technical Instructions that designated civil surgeons are required to follow for all immigration medical examinations.
Question 2: According to evidence-based practice, which tuberculosis screening method is preferred for BCG-vaccinated immigrants due to its higher specificity?
- Tuberculin skin test (TST) alone
- Interferon-gamma release assay (IGRA) (Correct answer)
- Chest X-ray alone
- Sputum culture
Correct answer: Interferon-gamma release assay (IGRA)
IGRAs are preferred for BCG-vaccinated individuals because they are not affected by prior BCG vaccination, resulting in fewer false-positive results.
Question 3: The vaccination requirements for immigration medical exams are derived from which primary evidence-based source?
- American Academy of Pediatrics Red Book
- CDC Advisory Committee on Immunization Practices (ACIP) recommendations (Correct answer)
- World Health Organization vaccination schedules
- State health department guidelines
Correct answer: CDC Advisory Committee on Immunization Practices (ACIP) recommendations
ACIP recommendations form the scientific foundation for all vaccination requirements in the immigration medical examination process.
Question 4: Which study design provides the highest level of evidence for evaluating vaccine efficacy?
- Case report
- Cohort study
- Randomized controlled trial (RCT) (Correct answer)
- Cross-sectional study
Correct answer: Randomized controlled trial (RCT)
Randomized controlled trials are considered the gold standard for establishing causation and efficacy because randomization minimizes confounding bias.
Question 5: The CDC updates its Technical Instructions for immigration medical exams primarily based on which factor?
- Congressional mandates only
- New epidemiological evidence and changing disease patterns (Correct answer)
- Annual agency budget cycles
- WHO emergency declarations only
Correct answer: New epidemiological evidence and changing disease patterns
Technical Instructions are revised when new scientific evidence emerges or when disease epidemiology changes in ways that affect public health risk to the United States.
Question 6: Evidence-based criteria for classifying a condition as 'Class A' in the immigration medical exam are primarily based on which characteristic?
- Economic burden of treatment in the U.S.
- Public health risk and potential for communicability (Correct answer)
- Country-of-origin disease statistics
- Availability of treatment in the applicant's home country
Correct answer: Public health risk and potential for communicability
Class A designations apply to conditions that pose a significant public health risk, particularly communicable diseases of public health significance.
Question 7: When clinical evidence from two different guidelines conflicts during an immigration medical exam, what should the civil surgeon do?
- Follow the most recently published guideline regardless of source
- Use clinical judgment and defer to CDC Technical Instructions as the controlling authority (Correct answer)
- Contact WHO for international consensus
- Apply whichever guideline produces the more conservative result
Correct answer: Use clinical judgment and defer to CDC Technical Instructions as the controlling authority
For immigration medical purposes, CDC Technical Instructions are the controlling authority; civil surgeons must adhere to them even if other clinical guidelines differ.
