[Blended Learning in Critical Care to Improve Quality of Care the ERIC-Training]. / Blended-Learning-Konzepte in der Intensivmedizin am Beispiel des ERIC-Trainings.

Communication and teamwork skills are, besides clinical knowledge, key components of high quality care in modern intensive care units. In light of high staff fluctuations among intensive care unit teams and disparities in clinical experience, an ongoing training is essential to ensure optimal performance in stressfull situations. Further, when implementing new procedures, an adequate concept for staff education is of utmost importance. Blended learning is a novel approach, combining autonomous web-based education and on-site workshops in order to improve the training process. Enhanced Recovery after Intensive Care (ERIC) is a newly developed telemedical intervention targeted at improving evidence-based practice in critical care, guided by quality indicators defined by the German Interdisciplinary Society of Emergency and Critical Care Medicine (DIVI). This telemedical intervention is supplemented with a blended-learning concept combining an e-learning website, simulator-based workshops and on-site training in order to expand the knowledge and practical skills regarding adherence to the quality indicators.

Monitor-based exoscopic 3D4k neurosurgical interventions: a two-phase prospective-randomized clinical evaluation of a novel hybrid device.

BACKGROUND: Promoting a disruptive innovation in microsurgery, exoscopes promise alleviation of physical strain and improved image quality through digital visualization during microneurosurgical interventions. This study investigates the impact of a novel 3D4k hybrid exoscope (i.e., combining digital and optical visualization) on surgical performance and team workflow in preclinical and clinical neurosurgical settings. METHODS: A pre-clinical workshop setting has been developed to assess usability and implementability through skill-based scenarios (neurosurgical participants n = 12). An intraoperative exploration in head and spine surgery (n = 9) and a randomized clinical study comparing ocular and monitor mode in supratentorial brain tumor cases (n = 20) followed within 12 months. Setup, procedure, case characteristics, surgical performance, and user experience have been analyzed for both ocular group (OG) and monitor group (MG). RESULTS: Brain tumor cases using frontal, frontoparietal, or temporal approaches have been identified as favorable use cases for introducing exoscopic neurosurgery. Mean monitor distance and angle were 180 cm and 10°. Surgical ergonomics when sitting improved significantly in MG compared with OG (P = .03). Hand-eye coordination required familiarization in MG. Preclinical data showed a positive correlation between lateral camera inclination and impact on hand-eye coordination (rs = 0.756, P = .01). There was no significant added surgical time in MG. Image quality in current generation 3D4k monitors has been rated inferior to optic visualization yet awaits updates. CONCLUSIONS: The hybrid exoscopic device can be integrated into established neurosurgical workflows. Currently, exoscopic interventions seem most suited for cranial tumor surgery in lesions that are not deep-seated. Ergonomics improve in monitor mode compared to conventional microsurgery.

Does Telemedical Support of First Responders Improve Guideline Adherence in an Offshore Emergency Scenario? A Simulator-Based Prospective Study.

OBJECTIVE: To investigate, in a simulator-based prospective study, whether telemedical support improves quality of emergency first response (performance) by medical non-professionals to being non-inferior to medical professionals. SETTING: In a simulated offshore wind power plant, duos (teams) of offshore engineers and teams of paramedics conducted the primary survey of a simulated patient. PARTICIPANTS: 38 offshore engineers and 34 paramedics were recruited by the general email invitation. INTERVENTION: Teams (randomised by lot) were supported by transmission technology and a remote emergency physician in Berlin. OUTCOME MEASURES: From video recordings, performance (17 item checklist) and required time (up to 15 min) were quantified by expert rating for analysis. Differences were analysed using two-sided exact Mann-Whitney U tests for independent measures, non-inferiority was analysed using Schuirmann one-sided test. The significance level of 5 % was Holm-Bonferroni adjusted in each family of pairwise comparisons. RESULTS: Nine teams of engineers with, nine without, nine teams of paramedics with and eight without support completed the task. Two experts quantified endpoints, insights into rater dependence were gained. Supported engineers outperformed unsupported engineers (p<0.01), insufficient evidence was found for paramedics (p=0.11). Without support, paramedics outperformed engineers (p<0.01). Supported engineers' performance was non-inferior (at one item margin) to that by unsupported paramedics (p=0.03). Supported groups were slower than unsupported groups (p<0.01). CONCLUSIONS: First response to medical emergencies in offshore wind farms with substantially delayed professional care may be improved by telemedical support. Future work should test our result during additional scenarios and explore interdisciplinary and ecosystem aspects of this support. TRIAL REGISTRATION NUMBER: DRKS00014372.
