Learning Objectives

  1. Distinguish EHR screening and clinical confirmation of drug resistance.
  2. Interpret center variation without inferring inappropriate treatment.
  3. Keep MRI prediction and tractography findings within their validation limits.

Questions

1. What did Caraway’s surgery recommendation outcome include?
Correct answer: B. The recommendation endpoint included invasive monitoring. Center-level variation does not by itself establish inappropriate decisions or treatment outcomes.
2. What did the Simmons EHR algorithm establish before manual review?
Correct answer: C. The phenotype was a rule-based case-finding tool; manual review confirmed drug resistance. Medication exposure is not equivalent to adequate failure.
3. With seizure freedom as the MRI model’s positive class, what does negative predictive value describe?
Correct answer: A. The negative class was non-seizure-free outcome. Modest external discrimination and observational validation constrain individual clinical use.
4. What is supported by Wreghitt’s 33-person tractography study?
Correct answer: D. Probabilistic tractography improved delineation and injury estimates correlated with visual-field severity. The observational study did not establish guaranteed margins or prevention.
