Background
Traditionally Danish clinical guidelines cover specific diagnoses. However these guidelines are not always suitable for the acute patients presenting at the Emergency Department (ED). In 2009 the ED at Kolding Hospital developed a pocket size guideline book containing the conditions most commonly encountered in the ED. At Holbaek University Hospital guidelines are developed by each specialty and are only available online at the hospital intranet. We wished to investigate the effect of a pocket size guideline book.
