Emergency department (ED) nurses care for victims of trauma almost daily. Although preservation of evidence is crucial, the ED is chaotic when a trauma patient arrives and staff members must do everything possible to save the patient's life. However, an integral responsibility of the staff nurse is collection and preservation of forensic evidence. This article provides insight into the process undertaken by a multidisciplinary team to develop a set of evidence-based guidelines for forensic evidence collection. The team compiled evidence from more than 20 articles and consultations with law enforcement officials and forensic experts. This information was used to develop a set of guidelines for forensic evidence collection in the ED or operating room. Staff educational needs presented some challenges. Training was designed to specifically address the roles of three major groups of staff: patient representatives and emergency and trauma nurses. Educational topics included evidence recognition, handling of clothing, gross/trace evidence, documentation, packaging of evidence, and use of the "chain-of-evidence" form. Practice modifications included development of a new "chain-of-evidence" form, a forensic cart in the operating room, and use of a collapsible plastic box for collection of clothing in the ED.

Nonfatal strangulation is a relatively newly recognized mechanism of injury that may not be taken seriously because of lack of physical injuries that many times accompany it. This comparison case series supports the importance of considering not only visually detected injuries but also symptoms the patient may be experiencing when determining diagnostics necessary to guide a treatment plan. A visually detectable injury is dependent on multiple factors. Bruises may occur with minimal pressure but may not be visible immediately after assault. Contrary to this, extensive bruising of the neck is not an accurate indicator of damage to underlying structures. The authors' experiences in these two cases signify the necessity of a comprehensive assessment utilizing both physical symptoms and assessments as the basis for determining nonfatal strangulation treatment plans.
