- BACKGROUND: Digital modalities which enable asynchronous learning, such as audio podcasts and videos demonstrating procedures, may benefit acquisition and retention of knowledge and clinical skills. The main objective of this nationwide cross-sectional survey study was to evaluate key aspects and factors related to usage of audio podcasts and procedural videos in anaesthesiology and intensive care.METHODS: A 20-item multiple-choice-question online survey was created through a consensus process including pilot testing among residents and consultants. Data were collected over a 3-month period, September-November 2023.RESULTS: The survey was completed by 466 anaesthetists. More than a third reported using procedural videos ≥1 time per week, whereas fewer than one in four participants used audio podcasts at least once per week. Multivariable logistic regression analysis showed that working at a university hospital, male sex, and younger age were independently associated with podcast use ≥1 time per week, with the highest odds ratio (OR) for younger age (<40 years vs. ≥40 years old; OR 5.86 (95% confidence interval 3.55-9.67), p < .001). Younger age was also significantly associated with higher frequency of video use (OR 1.71 (1.13-2.58), p = .011), while working predominantly in intensive care was associated with a lower frequency of video use. Podcasts were often used during commuting (42.3%), household work (30.7%), and exercise (24.9%), indicating a role in multi-tasking. Approximately half of respondents expressed that audio podcast-based learning has a moderate to very large positive impact on acquisition of theoretical knowledge, as well as practical skills. A vast majority, 85.2%, reported that procedural videos have a moderate to very large impact on development of clinical skills.CONCLUSION: Audio podcasts and procedural videos are appreciated tools with potential to supplement more traditional didactic techniques in anaesthesiology and intensive care. Procedural video use is common, with perceived large effects on development of clinical skills. Further data are needed to fully understand learning outcomes, quality of peer-review processes, and potential sex-differences.

- Objective Long-term cognitive decline is an adverse outcome after major surgery associated with increased risk for mortality and morbidity. We studied the cerebrospinal fluid (CSF) and serum biochemical inflammatory response to a standardized orthopedic surgical procedure and the possible association with long-term changes in cognitive function. We hypothesized that the CSF inflammatory response pattern after surgery would differ in patients having long-term cognitive decline defined as a composite cognitive z score of >= 1.0 compared to patients without long-term cognitive decline at 3 months postsurgery. Methods Serum and CSF biomarkers of inflammation and blood-brain barrier (BBB) integrity were measured preoperatively and up to 48 hours postoperatively, and cognitive function was assessed preoperatively and at 2 to 5 days and 3 months postoperatively. Results Surgery was associated with a pronounced increase in inflammatory biomarkers in both CSF and blood throughout the 48-hour study period. A principal component (PC) analysis was performed on 52 inflammatory biomarkers. The 2 first PC (PC1 and PC2) construct outcome variables on CSF biomarkers were significantly associated with long-term cognitive decline at 3 months, but none of the PC construct serum variables showed a significant association with long-term cognitive decline at 3 months. Patients both with and patients without long-term cognitive decline showed early transient increases of the astroglial biomarkers S-100B and glial fibrillary acidic protein in CSF, and in BBB permeability (CSF/serum albumin ratio). Interpretation Surgery rapidly triggers a temporal neuroinflammatory response closely associated with long-term cognitive outcome postsurgery. The findings of this explorative study require validation in a larger surgical patient cohort.

- This study aimed to compare screw placement accuracy and clinical aspects between Augmented Reality Surgical Navigation (ARSN) and free-hand (FH) technique. Twenty patients underwent spine surgery with screw placement using ARSN and were matched retrospectively to a cohort of 20 FH technique cases for comparison. All ARSN and FH cases were performed by the same surgeon. Matching was based on clinical diagnosis and similar proportions of screws placed in the thoracic and lumbosacral vertebrae in both groups. Accuracy of screw placement was assessed on postoperative scans according to the Gertzbein scale and grades 0 and 1 were considered accurate. Procedure time, blood loss and length of hospital stay, were collected as secondary endpoints. A total of 262 and 288 screws were assessed in the ARSN and FH groups, respectively. The share of clinically accurate screws was significantly higher in the ARSN vs FH group (93.9% vs 89.6%, p < 0.05). The proportion of screws placed without a cortical breach was twice as high in the ARSN group compared to the FH group (63.4% vs 30.6%, p < 0.0001). No statistical difference was observed for the secondary endpoints between both groups. This matched-control study demonstrated that ARSN provided higher screw placement accuracy compared to free-hand.
