Systematic review and narrative synthesis of competency-based medical education in anaesthesia.

BACKGROUND: Competency-based medical education (CBME) addresses the accountability of postgraduate training programmes to graduate specialists capable of independent practice. METHODS: We undertook a systematic review and narrative synthesis of the published CBME literature in anaesthesia training programmes to identify current practices and areas requiring further exploration. RESULTS: We grouped the 23 studies that met our inclusion criteria into the following categories: demonstrating outcomes of CBME, developing a consensus on an achievable CBME curriculum, CBME curriculum framework, design and implementation of workplace-based assessment (WBA) tools, trainee self-assessment, perceptions of trainees and supervisors on WBA tools, and technological solutions for assessment and feedback. Included studies reported variable success in reaching consensus in competency outcome frameworks for sequenced progression and limited research on approaches to curriculum delivery, whilst the majority of studies focused on workplace assessment. Studies supported the use of entrustment scales, where assessors make a judgement on the extent to which the trainee can manage a case independently. While evidence supported the reliability of WBA tools, and predicted the numbers needed for high-stakes decisions, areas of concern related to factors influencing the value WBA tools in promoting trainee learning, and variable perceptions of their value in making decisions on progression. CONCLUSIONS: Evidence on outcomes of CBME was limited to acquisition of specific competencies during training. The large number of unanswered questions and the dearth of studies across the core components of CBME suggest that we need a collaborative approach to create the evidence required to implement CBME wisely and cost effectively, to have positive impacts on patients, trainees, and healthcare systems.

Association of Neonatal Glycemia With Neurodevelopmental Outcomes at 4.5 Years.

Importance: Hypoglycemia is common during neonatal transition and may cause permanent neurological impairment, but optimal intervention thresholds are unknown. Objective: To test the hypothesis that neurodevelopment at 4.5 years is related to the severity and frequency of neonatal hypoglycemia. Design, Setting, and Participants: The Children With Hypoglycemia and Their Later Development (CHYLD) Study is a prospective cohort investigation of moderate to late preterm and term infants born at risk of hypoglycemia. Clinicians were masked to neonatal interstitial glucose concentrations; outcome assessors were masked to neonatal glycemic status. The setting was a regional perinatal center in Hamilton, New Zealand. The study was conducted from December 2006 to November 2010. The dates of the follow-up were September 2011 to June 2015. Participants were 614 neonates born from 32 weeks' gestation with at least 1 risk factor for hypoglycemia, including diabetic mother, preterm, small, large, or acute illness. Blood and masked interstitial glucose concentrations were measured for up to 7 days after birth. Infants with hypoglycemia (whole-blood glucose concentration <47 mg/dL) were treated to maintain blood glucose concentration of at least 47 mg/dL. Exposures: Neonatal hypoglycemic episode, defined as at least 1 consecutive blood glucose concentration less than 47 mg/dL, a severe episode (<36 mg/dL), or recurrent (≥3 episodes). An interstitial episode was defined as an interstitial glucose concentration less than 47 mg/dL for at least 10 minutes. Main Outcomes and Measures: Cognitive function, executive function, visual function, and motor function were assessed at 4.5 years. The primary outcome was neurosensory impairment, defined as poor performance in one or more domains. Results: In total, 477 of 604 eligible children (79.0%) were assessed. Their mean (SD) age at the time of assessment was 4.5 (0.1) years, and 228 (47.8%) were female. Those exposed to neonatal hypoglycemia (280 [58.7%]) did not have increased risk of neurosensory impairment (risk difference [RD], 0.01; 95% CI, -0.07 to 0.10 and risk ratio [RR], 0.96; 95% CI, 0.77 to 1.21). However, hypoglycemia was associated with increased risk of low executive function (RD, 0.05; 95% CI, 0.01 to 0.10 and RR, 2.32; 95% CI, 1.17 to 4.59) and visual motor function (RD, 0.03; 95% CI, 0.01 to 0.06 and RR, 3.67; 95% CI, 1.15 to 11.69), with highest risk in children exposed to severe, recurrent, or clinically undetected (interstitial episodes only) hypoglycemia. Conclusions and Relevance: Neonatal hypoglycemia was not associated with increased risk of combined neurosensory impairment at 4.5 years but was associated with a dose-dependent increased risk of poor executive function and visual motor function, even if not detected clinically, and may thus influence later learning. Randomized trials are needed to determine optimal screening and intervention thresholds based on assessment of neurodevelopment at least to school age.
