Scandinavian guidelines for initial management of minor and moderate head trauma in children

Ramona Astrand, Christina Rosenlund, Johan Undén
2016 BMC Medicine  
For elements with low evidence, a modified Delphi process was used for consensus, which included relevant clinical stakeholders.  ...  The guidelines separate mild head trauma patients into high-, medium-and low-risk categories, favouring observation for mild, low-risk patients as an attempt to reduce CT scans in children.  ...  Routine repeat CT is not recommended for all admitted children after head trauma.  ...

An observational study of compliance with the Scandinavian guidelines for management of minimal, mild and moderate head injury

Ben Heskestad, Knut Waterloo, Tor Ingebrigtsen, Bertil Romner, Marianne Harr, Eirik Helseth
2012 Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine  
The Scandinavian guidelines for management of minimal, mild and moderate head injuries were developed to provide safe and cost effective assessment of head injured patients.  ...  A substantial number of patients are exposed to over-triage, involving unnecessary radiation from CT examinations, and unnecessary costs from hospital admissions.  ...  For minimal head injuries, the guidelines recommend return to home without CT examination, unless additional risk factors are present.  ...
