Multicenter Study
Development and validation of a model to predict the need for emergency front-of-neck airway procedures in trauma patients.
The present study aimed to develop and validate a model for predicting the need for emergency front-of neck airway (eFONA) procedures among trauma patients. This was a multicentre retrospective cohort study using data from the Japan Trauma Data Bank between January 2004 and December 2017. Only adult trauma patients were included. ⋯ Setting the cut-off value at one for rule-out, the sensitivity and negative likelihood ratios were 0.86 and 0.22, respectively. Setting the cut-off value at two for rule-in, the specificity and positive likelihood ratios were 0.91 and 6.6, respectively. The present scoring system may assist in predicting the need for emergency front-of neck airway procedures among the general trauma population.

Comparative Study
Rational planning of operating lists: a prospective comparison of 'booking to the mean' vs. 'probabilistic case scheduling' in urology.
The efficient use of operating theatres requires accurate case scheduling. One common method is 'booking to the mean'. Here, the mean times for individual operations are summed to approximate the time allocated to the list. ⋯ Booking to the mean resulted in 53/60 (88%) lists over-running and correctly predicted the finish times in just 13% of lists. Out of 264 patients, 36 (14%) were cancelled on the day due to over-runs in 24/60 (40%) lists. In contrast, probabilistic scheduling correctly predicted an over-run or under-run in 77% of lists, which would have allowed the case mix to be adjusted to prevent cancellation and optimise utilisation.

Which journals cite work published in anaesthetic journals is of potential interest to authors, editors and publishers. We analysed citations made in 2017-2018 for articles, reviews, editorials and letters published by 12 anaesthetic journals in 2016, using the Web of Science™ citation index platform. We analysed 12,544 citations made for 3518 items. ⋯ The median (IQR [range]) proportion of citations made by the same journal that published the items (i.e. 'self-citations') was 15% (11-17% [5-32%]). There were 1305/1932 (68%) citations made by North American journals for items published in North American journals and 1712/2063 (83%) citations made by European journals for items published in European journals, p < 0.0001. Our analysis may inform authors, editors and publishers where to submit work, what editorial policy to pursue and what journal strategy to follow, respectively.
