The power of written word: Reflection reduces errors of omission.

BACKGROUND: Medical trainees are expected to perform complex tasks while experiencing interruptions, which increases susceptibility to errors of omission. In our study, we examine whether documentation of clinical encounters increases reflective thinking and reduces errors of omission among novice learners in a simulated setting. METHODS: In 2021, 56 senior medical students participated in a simulated paging curriculum involving urgent inpatient cross-cover scenarios (sepsis and atrial fibrillation). Students responded to pages from standardized registered nurses (SRNs) via telephone, gathered history, and discussed clinical decision-making. Following the phone encounter, students documented a brief note (documentation encounter). A 'phone' score (number of checklist items completed in the phone encounter) and a 'combined' score (number of checklist items completed in the phone and documentation encounters) were calculated. Data were analyzed for differences between the phone scores (control) and combined scores using T-tests and McNemar test of symmetry. FINDINGS: Fifty-four students (96%) participated. Combined scores were higher than phone scores for sepsis (72.8 ± 11.3% vs. 67.9 ± 11.9%, p < 0.001) and atrial fibrillation (74.0 ± 10.1% vs. 67.6 ± 10.0%, p < 0.001) cases. Important items, such as ordering blood cultures for sepsis (p = 0.023) and placing the patient on telemetry for atrial fibrillation (p = 0.013), were more likely to be present when a note was documented. DISCUSSION: This study suggests that documentation provides a mechanism for learners to reflect, which could increase important diagnostic and therapeutic interventions. CONCLUSION: Documentation by novice medical learners may improve patient care by allowing for reflection and reducing errors of omission.

MOG-IgG1 and co-existence of neuronal autoantibodies.

BACKGROUND: The presence of co-existent neuronal antibodies (neuronal-IgG) in patients with myelin oligodendrocyte glycoprotein immunoglobulin G (MOG-IgG1) is not yet well understood. OBJECTIVES: The aim of this study was to investigate the co-existence of a broad range of neuronal-IgG in MOG-IgG1+ patients. METHODS: MOG-IgG1+ patients were tested for 17 neuronal-IgGs in cerebrospinal fluid (CSF) and serum including NMDA-R-IgG, AMPA-R-IgG, GABAB-R-IgG, LGI1-IgG, CASPR2-IgG, GABAA-R-IgG, GAD65-IgG, mGLUR1-IgG, DPPX-IgG, CRMP5-IgG, amphiphysin-IgG, PCA1,2,Tr, and ANNA1,2,3. Clinical and radiological features of MOG-IgG1+ with NMDA-R-IgG in CSF were compared to a control cohort of MOG-IgG1+ patients without NMDA-R-IgG. RESULTS: A total of 376 MOG-IgG1+ patients underwent testing for neuronal-IgGs. Serum testing for neuronal-IgGs (113 adults, 142 children) identified one child with NMDA-R-IgG (0.7%), one child with CASPR2-IgG (0.7%), one adult with LGI1-IgG (0.9%) and one adult with GABAA-R-IgG (0.9%). CSF testing for neuronal-IgGs (97 adults, 169 children) identified seven children (4%) and seven adults (7%) with NMDA-R-IgG, and one adult with GABAA-R-IgG (1%). The MOG-IgG1+/NMDA-R-IgG+ patients had a median age of 17 (range: 2-39) years. Features associated with MOG-IgG1+/NMDA-R-IgG+ included encephalopathy (p = 0.001), seizures (p = 0.045), and leptomeningeal enhancement (p = 0.045). CONCLUSION: NMDA-R-IgG was the most frequently detected neuronal-IgG to co-exist with MOG-IgG1. MOG-IgG1+/NMDA-R-IgG+ patients most often presented with encephalopathy and seizures. Testing for MOG-IgG1 and NMDA-R-IgG may be warranted in patients with encephalopathy and inflammatory demyelinating syndromes.

Are Predictive Energy Expenditure Equations in Ventilated Surgery Patients Accurate?

BACKGROUND:: While indirect calorimetry (IC) is the gold standard used to calculate specific calorie needs in the critically ill, predictive equations are frequently utilized at many institutions for various reasons. Prior studies suggest these equations frequently misjudge actual resting energy expenditure (REE) in medical and mixed intensive care unit (ICU) patients; however, their utility for surgical ICU (SICU) patients has not been fully evaluated. Therefore, the objective of this study was to compare the REE measured by IC with REE calculated using specific calorie goals or predictive equations for nutritional support in ventilated adult SICU patients. MATERIALS AND METHODS:: A retrospective review of prospectively collected data was performed on all adults (n = 419, 18-91 years) mechanically ventilated for >24 hours, with an Fio2 ≤ 60%, who met IC screening criteria. Caloric needs were estimated using Harris-Benedict equations (HBEs), and 20, 25, and 30 kcal/kg/d with actual (ABW), adjusted (ADJ), and ideal body (IBW) weights. The REE was measured using IC. RESULTS:: The estimated REE was considered accurate when within ±10% of the measured REE by IC. The HBE, 20, 25, and 30 kcal/kg/d estimates of REE were found to be inaccurate regardless of age, gender, or weight. The HBE and 20 kcal/kg/d underestimated REE, while 25 and 30 kcal/kg/d overestimated REE. Of the methods studied, those found to most often accurately estimate REE were the HBE using ABW, which was accurate 35% of the time, and 25 kcal/kg/d ADJ, which was accurate 34% of the time. This difference was not statistically significant. CONCLUSION:: Using HBE, 20, 25, or 30 kcal/kg/d to estimate daily caloric requirements in critically ill surgical patients is inaccurate compared to REE measured by IC. In SICU patients with nutrition requirements essential to recovery, IC measurement should be performed to guide clinicians in determining goal caloric requirements.
