RESUMEN
BACKGROUND: As part of the worldwide call to enhance the safety of patient handovers of care, the Association of American Medical Colleges (AAMC) requires that all graduating students "give or receive a patient handover to transition care responsibly" as one of its Core Entrustable Professional Activities (EPAs) for Entering Residency. Students therefore require educational activities that build the necessary teamwork skills to perform structured handovers. To date, a reliable instrument designed to assess teamwork competencies, like structured communication, throughout their preclinical and clinical years does not exist. METHOD: Our team developed an assessment instrument that evaluates both the use of structured communication and two additional teamwork competencies necessary to perform safe patient handovers. This instrument was utilized to assess 192 handovers that were recorded from a sample of 229 preclinical medical students and 25 health professions students who participated in a virtual course on safe patient handovers. Five raters were trained on utilization of the assessment instrument, and consensus was established. Each handover was reviewed independently by two separate raters. RESULTS: The raters achieved 72.22 % agreement across items in the reviewed handovers. Krippendorff's alpha coefficient to assess inter-rater reliability was 0.6245, indicating substantial agreement among the raters. A confirmatory factor analysis (CFA) demonstrated the orthogonal characteristics of items in this instrument with rotated item loadings onto three distinct factors providing preliminary evidence of construct validity. CONCLUSIONS: We present an assessment instrument with substantial reliability and preliminary evidence of construct validity designed to evaluate both use of structured handover format as well as two team competencies necessary for safe patient handovers. Our assessment instrument can be used by educators to evaluate learners' handoff performance as early as their preclinical years and is broadly applicable in the clinical context in which it is utilized. In the journey to optimize safe patient care through improved teamwork during handovers, our instrument achieves a critical step in the process of developing a validated assessment instrument to evaluate learners as they seek to accomplish this goal.

BACKGROUND: Fatty acid amide hydrolase 2 (FAAH2) is a hydrolase that mediates the degradation of endocannabinoids in man. Alterations in the endocannabinoid system are associated with a wide variety of neurologic and psychiatric conditions, but the phenotype and biochemical characterization of patients with genetic defects of FAAH2 activity have not previously been described. We report a male with autistic features with an onset before the age of 2 years who subsequently developed additional features including anxiety, pseudoseizures, ataxia, supranuclear gaze palsy, and isolated learning disabilities but was otherwise cognitively intact as an adult. METHODS AND RESULTS: Whole exome sequencing identified a rare missense mutation in FAAH2, hg19: g.57475100G > T (c.1372G > T) resulting in an amino acid change (p.Ala458Ser), which was Sanger confirmed as maternally inherited and absent in his healthy brother. Alterations in lipid metabolism with abnormalities of the whole blood acyl carnitine profile were found. Biochemical and molecular modeling studies confirmed that the p.Ala458Ser mutation results in partial inactivation of FAAH2. Studies in patient derived fibroblasts confirmed a defect in FAAH2 activity resulting in altered levels of endocannabinoid metabolites. CONCLUSIONS: We propose that genetic alterations in FAAH2 activity contribute to neurologic and psychiatric disorders in humans.
