Der Beitrag befasst sich mit Teilaspekten bei der Entwicklung von Methoden zur gezielten, bearbeitungsparallelen Oberflächenkonditionierung beim Tiefbohren. Konkret handelt es sich um messtechnische und simulationsbasierte Ansätze zur Identifikation von thermomechanischen Prozesszuständen beim BTA- und ELB-Verfahren. Hierbei werden Möglichkeiten zur Gewinnung von Prozessdaten sowohl mit einer in-situ eingesetzten Sensorik als auch mit begleitend durchgeführten FEM-Simulationen betrachtet. Diese Daten bilden die Grundlage einer Prozessregelung für die beiden Tiefbohrverfahren. Im zweiten Teil werden nun die Arbeiten und Ergebnisse zum ELB-Tiefbohren behandelt.   The article deals with aspects of developing methods specifically for surface conditioning in deep hole drilling parallel to machining. This involves metrological and simulation-based approaches for identifying thermo-mechanical process conditions in both BTA and ELB process. Ways for obtaining process data both with sensor technology used in-situ and with FEM simulations performed concomitantly are investigated. These data form the basis of a deep hole process control. The second part presents the work and the results on single lip deep hole drilling.

IntroductionEmergent paediatric intubation is an infrequent but high-stakes procedure in the paediatric emergency department (PED). Successful intubations depend on efficient and accurate preparation. The aim of this study was to use airway drills (brief in-situ simulations) to identify gaps in our paediatric endotracheal intubation preparation process, to improve on our process and to demonstrate sustainability of these improvements over time in a new staff cohort.MethodThis was a single-centre, simulation-based improvement study. Baseline simulated airway drills were used to identify barriers in our airway preparation process. Drills were scored for time and accuracy on an iteratively developed 16-item rubric. Interventions were identified and their impact was measured using simulated airway drills. Statistical analysis was performed using unpaired t-tests between the three data collection periods.ResultsTwenty-five simulated airway drills identified gaps in our airway preparation process and served as our baseline performance. The main problem identified was that staff members had difficulty locating essential airway equipment. Therefore, we optimised and implemented a weight-based airway cart. We demonstrated significant improvement and sustainability in the accuracy of obtaining essential airway equipment from baseline to postintervention (62% vs 74%; p=0.014), and postintervention to sustainability periods (74% vs 77%; p=0.573). Similarly, we decreased and sustained the time (in seconds) required to prepare for a paediatric intubation from baseline to postintervention (173 vs 109; p=0.001) and postintervention to sustainability (109 vs 103; p=0.576).ConclusionsSimulated airway drills can be used as a tool to identify process gaps, measure and improve paediatric intubation readiness.

Patient safety incidents occur throughout healthcare and early reports have exposed how deficiencies in ‘human factors’ have contributed to mortality in endoscopy. Recognising this, in the UK, the Joint Advisory Group for Gastrointestinal Endoscopy have implemented a number of initiatives including the ‘Improving Safety and Reducing Error in Endoscopy’ (ISREE) strategy. Within this, simulation training in human factors and Endoscopic Non-Technical Skills (ENTS) is being developed. Across healthcare, simulation training has been shown to improve team skills and patient outcomes. Although the literature is sparse, integrated and in situ simulation modalities have shown promise in endoscopy. Outcomes demonstrate improved individual and team performance and development of skills that aid clinical practice. Additionally, the use of simulation training to detect latent errors in the working environment is of significant value in reducing error and preventing harm. Implementation of simulation training at local and regional levels can be successfully achieved with collaboration between organisational, educational and clinical leads. Nationally, simulation strategies are a key aspect of the ISREE strategy to improve ENTS training. These may include integration of simulation into current training or development of novel simulation-based curricula. However used, it is evident that simulation training is an important tool in developing safer endoscopy.
