Multicenter Study
Factors associated with failed epidural blood patch after accidental dural puncture in obstetrics: a prospective, multicentre, international cohort study.
Unsuccessful epidural blood patch is associated with higher lumbar levels, shorter time between puncture & patch, and with patients with migraine history.

Randomized Controlled Trial
Exposure to incivility does not hinder speaking up: a randomised controlled high-fidelity simulation-based study.
Speaking up with concerns is critical for patient safety. We studied whether witnessing a civil (i.e. polite, respectful) response to speaking up would increase the occurrence of further speaking up by hospital staff members as compared with witnessing a pseudo-civil (i.e. vague and slightly dismissive) or rude response. ⋯ Our study challenges current assumptions about the interplay of civility and speaking up behaviour in healthcare.

Editorial Comment
Trials with 'non-significant' results are not insignificant trials: a common significance threshold distorts reporting and interpretation of trial results.
We discuss a newly published study examining how phrases are used in clinical trials to describe results when the estimated P-value is close to (slightly above or slightly below) 0.05, which has been arbitrarily designated by convention as the boundary for 'statistical significance'. Terms such as 'marginally significant', 'trending towards significant', and 'nominally significant' are well represented in biomedical literature, but are not actually scientifically meaningful. ⋯ Instead, investigators could simply report their findings: effect sizes, P-values, and confidence intervals (or their Bayesian equivalents), and leave it to the discerning reader to infer the clinical applicability and importance. Our goal should be to move away from describing studies (or trials) as positive or negative based on an arbitrary P-value threshold, and rather to judge whether the scientific evidence provided is informative or uninformative.

Exposure to general anaesthesia in children might increase the risk of long-term behavioural problems. It is unclear if any behavioural changes in the short term after anaesthesia could be associated with long-term problems. The goal of the current study was to evaluate the short-term trajectory of parent-reported behaviour measured by the Behaviour Assessment System for Children, third edition (BASC-3) amongst children aged 2.5-6 yr who underwent general anaesthesia for elective surgery. ⋯ Anaesthesia for elective surgery in young children was associated with a small decrease in internalising problems but no changes in other areas of behavioural problems when assessed at 3 months postoperatively, including in children with prior exposure to anaesthesia.

A clinical scoring system to estimate the likelihood that a reaction represents a perioperative immediate hypersensitivity reaction has been devised using a Delphi consensus process. Agreement of this clinical scoring system with the outcome of allergological assessment would allow the use of this tool in post-resuscitation and subsequent management of suspected perioperative immediate hypersensitivity reaction and potentially as a new standard reference for clinical investigations. ⋯ The Hypersensitivity Clinical Scoring Scheme predicts allergic perioperative immediate hypersensitivity using features of the acute syndrome. This approach could guide algorithms for the post-resuscitative management of suspected perioperative immediate hypersensitivity, and identify patients requiring drug provocation challenge.
