Neurologic complications associated with regional anesthesia and pain medicine practice are extremely rare. The ASRA Practice Advisory on Neurologic Complications in Regional Anesthesia and Pain Medicine addresses the etiology, differential diagnosis, prevention, and treatment of these complications. This Advisory does not focus on hemorrhagic and infectious complications, because they have been addressed by other recent ASRA Practice Advisories. The current Practice Advisory offers recommendations to aid in the understanding and potential limitation of neurologic complications that may arise during the practice of regional anesthesia and pain medicine.

This Practice Advisory presents a comprehensive and evidence-based set of position statements and recommendations for the use of contrast media in interventional pain procedures. The advisory was established by an international panel of experts under the auspices of 11 multinational and multispecialty organizations based on a comprehensive review of the literature up to December 31, 2019. The advisory discusses the risks of using gadolinium-based contrast agents. These include nephrogenic systemic fibrosis, gadolinium brain deposition/retention, and encephalopathy and death after an unintentional intrathecal gadolinium injection. The advisory provides recommendations on the selection of a specific gadolinium-based contrast agent in patients with renal insufficiency, those who had multiple gadolinium-enhanced magnetic resonance imaging examinations, and in cases of paraspinal injections. Additionally, recommendations are made for patients who have a history of mild, moderate, or severe hypersensitivity reactions to contrast medium.

In 2018, the American Board of Anesthesiology (ABA) became the first US medical specialty certifying board to incorporate an Objective Structured Clinical Examination (OSCE) into its initial certification examination system. Previously, the ABA’s staged examination system consisted of 2 written examinations (the BASIC and ADVANCED examinations) and the Standardized Oral Examination (SOE). The OSCE and the existing SOE are now 2 separate components of the APPLIED Examination. This report presents the results of the first-year OSCE administration. A total of 1410 candidates took both the OSCE and the SOE in 2018. Candidate performance approximated a normal distribution for both the OSCE and the SOE, and was not associated with the timing of the examination, including day of the week, morning versus afternoon session, and order of the OSCE and the SOE. Practice-based Learning and Improvement was the most difficult station, while Application of Ultrasonography was the least difficult. The correlation coefficient between SOE and OSCE scores was 0.35 ([95% confidence interval {CI}, 0.30–0.39]; P < .001). Scores for the written ADVANCED Examination were modestly correlated with scores for the SOE ( r = 0.29 [95% CI, 0.25–0.34]; P < .001) and the OSCE ( r = 0.15 [95% CI, 0.10–0.20]; P < .001). Most of the candidates who failed the SOE passed the OSCE, and most of the candidates who failed the OSCE passed the SOE. Of the 1410 candidates, 77 (5.5%) failed the OSCE, 155 (11.0%) failed the SOE, and 25 (1.8%) failed both. Thus, 207 (14.7%) failed at least 1 component of the APPLIED Examination. Adding an OSCE to a board certification examination system is feasible. Preliminary evidence indicates that the OSCE measures aspects of candidate abilities distinct from those measured by other examinations used for initial board certification.

The American Board of Anesthesiology (ABA) has been administering an oral examination as part of its initial certification process since 1939. Among the 24 member boards of the American Board of Medical Specialties, 13 other boards also require passing an oral examination for physicians to become certified in their specialties. However, the methods used to develop, administer, and score these examinations have not been published. The purpose of this report is to describe the history and evolution of the anesthesiology Standardized Oral Examination, its current examination development and administration, the psychometric model and scoring, physician examiner training and auditing, and validity evidence. The many-facet Rasch model is the analytic method used to convert examiner ratings into scaled scores for candidates and takes into account how difficult grader examiners are and the difficulty of the examination tasks. Validity evidence of the oral examination includes that it measures aspects of clinical performance not accounted for by written certifying examinations, and that passing the oral examination is associated with a decreased risk of subsequent license actions against the anesthesiologist. Explaining the details of the Standardized Oral Examination provides transparency about this component of initial certification in anesthesiology.

This study compared anesthesiology residency graduates’ written certification examination performance before and after the American Board of Anesthesiology (ABA) introduced the staged examination system. After equating test scores using common test items, the first 2 cohorts (2013, 2014) in the staged system scored 7.1 points and 8.3 points higher than the 2011 baseline cohort in the former examination system. The 2013 and 2014 cohorts’ pass rates (94.2% and 95.9%) were also higher than the 2011 and 2012 cohorts (91.9% and 92.6%) if a common standard had been applied. The staged examination system may be associated with improved knowledge of anesthesiology graduates.
