A short cut review was carried out to establish whether a staff debriefing session after involvement in a traumatic resuscitation reduces stress and anxiety, reduces sickness, improves team working and morale and improves staff retention. Four papers presented the best evidence to answer the question. ⋯ However, there is some desire among staff for it to occur. Further research is needed and in the meantime local advice should be followed.

Tranexamic acid (TXA) reduces bleeding and mortality. Recent trials have demonstrated improved survival with shorter intervals to TXA administration. The aims of this service evaluation were to assess the interval from injury to TXA administration and describe the characteristics of patients who received TXA pre-hospital and in-hospital. ⋯ Prehospital administration of TXA is associated with a shorter interval from injury to drug delivery. Identifying a proportion of patients at risk of haemorrhage remains a challenge. However, further reinforcement is needed to empower pre-hospital clinicians to administer TXA to trauma patients without overt signs of shock.

Previous research suggests that there is an association between domestic violence (DV) and self-harm (SH). Yet, the prevalence and clinical significance of DV among individuals presenting acutely to hospital with SH in the UK is unknown. ⋯ Our findings suggest that DV victimisation is more prevalent among those presenting to ED with self-harm than among the general population of ED attenders, and that the presence of DV may signify increased risk among those presenting to ED with SH.

In this two-part series on sources of bias in studies of diagnostic test performance, we outline common errors and optimal conditions during three study phases: patient selection, interpretation of the index test and disease verification by a gold standard. Here in part 1, biases associated with suboptimal participant selection are discussed through the lens of partial verification bias and spectrum bias, both of which increase the proportion of participants who are the 'sickest of the sick' or the 'wellest of the well.' Especially through retrospective methodology, partial verification introduces bias by including patients who are test positive by a gold standard, since patients with a positive index test are more likely to go on to further gold standard testing. ⋯ After reading part 1, the informed clinician should be better able to judge the quality of a diagnostic test study, its inherent limitations and whether its results could be generalisable to their practice. Part 2 will describe how interpretation of the index test and disease verification by a gold standard can contribute to diagnostic test bias.
