Understanding the components of a Trauma Data Bank System (TDBS) is important, whether one is to use registry data for research or administrative purposes by an institution or a nation. TDBS has been designed to serve a number of purposes, including quality of life improvement, injury prevention, clinical research, and policy development. This review describes the history of trauma registry in the world and key components of TDBS. A detailed review of english-language articles on trauma registry was performed using MEDLINE searches. In addition, relevant articles from non-indexed journals were identified with Google Scholar. Since their beginning over 30 years ago, trauma registries have not fully been established in most developing countries. The following elements play key roles in the creation of trauma data bank: 1) study design, 2) inclusion and exclusion criteria, 3) collected variables, 4) registry software, 5) registry staff and training, and 6) data management strategies. By reviews in the articles, guidelines for the design and implementation of trauma registries are given. The final goal of this review is to make an application to establishment the futures of Korean Trauma Data Bank System.
