Journal of Trauma Nursing: January/February 2020 - Volume 27 - Issue 1 - p 58-62 doi: 10.1097/JTN.0000000000000483 Buy Metrics Abstract Violence is a growing public health problem worldwide. Nurses increasingly must perform forensic procedures with the responsibility to collect, document, preserve, and store evidence that may be used in the investigation of a violent crime. However, few nurses receive education in forensic evidence collection as part of their training. This study aimed to evaluate the relationship between nurses' knowledge and performance of forensic evidence procedures. This is a descriptive survey study of nurses working in a prehospital emergency care service in Aracaju, Brazil. A 32-question survey related to forensic evidence knowledge and procedures was completed by 128 nurses. Descriptive statistics and Kendall's Tau-b were used to describe the sample and evaluate correlations. Results revealed an overall linear relationship between knowledge and performance of forensic evidence procedures (r = .69). The strongest correlation was between knowledge and documentation (r = .71). Weaker correlations were demonstrated between knowledge and evidence collection (r = .47), evidence preservation (r = .47), and overall evidence procedure execution (r = .53). Forensic nursing knowledge is related to forensic evidence procedure performance. Although the study showed that nurses agreed forensic evidence procedures are important for criminal investigations, most reported they were unprepared to carry out these procedures. The need for additional training and adherence to established institutional protocols are identified as contributing factors. Copyright © 2020 by the Society of Trauma Nurses.
