Background: Trauma guidelines on spinal motion restriction (SMR) have changed drastically in recent years. An international group of experts explored whether consensus could be reached and if guidelines on SMR performed by trained lifeguards and prehospital EMS following in-water traumatic spinal cord injury (TSCI) should also be changed.

Methods: An international three-round Delphi process was conducted from October 2022 to November 2023.

Head injuries related to bicycle collisions and helmet use - an observational study.

Objectives: In Denmark, the use of bicycles is widespread, and head injuries are often seen in cyclists involved in collisions. Despite the well-known effects of using a helmet to reduce head injuries, using helmets is not mandatory in Denmark. The primary objective of this study was to provide data regarding injury outcomes and helmet usage.

Poor socioeconomic outcomes: Completion of the final examination after lower secondary education mitigates risks associated with gestational age.

Aim: To investigate the influence of gestational age (GA) on the association between completion of the final examination after 10-11 years of basic education and education, financial independence and income in early adulthood.

Methods: A nationwide register-based study including individuals born in Denmark between 1990 and 1992. Completion of the examination was evaluated at age 18 and education, financial independence and income at age 28.

Treat and release: an observational study of non-conveyed high-acuity dispatches in a Danish emergency medical system.

Non-conveyance refers to the practice of treating a patient on-site without transporting them to a medical facility. It may decrease unnecessary hospital transfers and improve patient satisfaction. Nonetheless, ensuring patient safety remains paramount.

Perceptions of medical students on narrow learning objectives and structured debriefing in medical escape rooms: a qualitative study.

Background: Escape rooms are increasingly used in medical education as a complementary learning technique or even alternative to traditional educational approaches. Few studies focus on debriefing following medical escape rooms and how escape rooms can be used to achieve pre-defined learning objectives.
