ABSTRACT
Prone positioning reduces mortality in the management of intubated patients with moderate-to-severe acute respiratory distress syndrome. It allows improvement in oxygenation by improving ventilation/perfusion ratio mismatching.Because of its positive physiological effects, prone positioning has also been tested in non-intubated, spontaneously breathing patients, or "awake" prone positioning. This review provides an update on awake prone positioning for hypoxaemic respiratory failure, in both coronavirus disease 2019 (COVID-19) and non-COVID-19 patients. In non-COVID-19 acute respiratory failure, studies are limited to a few small nonrandomised studies and involved patients with different diseases. However, results have been appealing with regard to oxygenation improvement, especially when combined with noninvasive ventilation or high-flow nasal cannula.The recent COVID-19 pandemic has led to a major increase in hospitalisations for acute respiratory failure. Awake prone positioning has been used with the aim to prevent intensive care unit admission and mechanical ventilation. Prone positioning in conscious, non-intubated COVID-19 patients is used in emergency departments, medical wards and intensive care units.Several trials reported an improvement in oxygenation and respiratory rate during prone positioning, but impacts on clinical outcomes, particularly on intubation rates and survival, remain unclear. Tolerance of prolonged prone positioning is an issue. Larger controlled, randomised studies are underway to provide results concerning clinical benefit and define optimised prone positioning regimens.

Anatomical dissection on cadavers can be a source of anxiety for medical students. Studies in other stressful settings have shown a reduction in anxiety when there is background music. The objective of this study was to determine if music can have an impact on student anxiety, student satisfaction, and student performance in dissection room. This cluster randomized interventional trial included 187 second-year medical students. The intervention was standardized background music, selected based on the literature, with a tempo of between 60 and 80 bpm. Six balanced clusters were randomized (1:1) to music or no music during dissection sessions. The main assessment criterion was a validated self-evaluation scale score for anxiety, the State Trait Anxiety Inventory. Student satisfaction was measured using a visual analog scale and dissection performance was evaluated by an examination. The outcomes were analyzed with mixed models adjusted on group effect, chronic anxiety, and confounding factors. A significant (58%) relative decrease in acute anxiety, odds ratio 0.423 [0.160; 0.710] was found for the music intervention group. Music also had a positive impact on performance with students in the intervention group attaining higher grades than those in the control group (0.42/10 higher, P = 0.0016). The study also showed a nonsignificant increase in satisfaction with 0.37 extra points (P = 0.137) in the intervention group. Background music had a significant impact on anxiety in the dissection room and on technical and theoretical performance in the subsequent anatomy examination. This music intervention could be extended to other stressful work environments.

BACKGROUND: The experience feedback committee (EFC) is a tool designed to involve medical teams in patient safety management, through root cause analysis (RCA) within the team. OBJECTIVES: To investigate the functioning of EFCs in the departments of a large university-affiliated hospital in France and to consider its potential contribution to the management of patient safety. METHODS: Cross-sectional, observational study, based on an analysis of the documents produced by the EFCs for 1 year. Data were collected independently by two investigators in meeting minutes, adverse event reports and event analysis reports. RESULTS: The study included all 20 EFCs operating in the hospital's medical departments. During the study year, committees held 164 meetings, reviewed 1707 adverse events, conducted 91 event analyses and decided on 206 corrective actions. The median number of corrective actions adopted by each EFC was five actions (range, 0-62). A root cause analysis (RCA) was present in 76% of the analysis reports, and these analyses were complete in only 23% of the reports. There was also a lack of planning corrective actions: an implementation deadline was only defined in 26% of the actions. CONCLUSIONS: Healthcare professionals adhered to the system-based approach to patient safety, but we observed difficulties in holding regular meetings and deviations from the theoretical framework. These findings confirm the difficulties of practicing RCA in the healthcare setting. Nevertheless, EFCs can be vectors of safety culture and teamwork.
