    Background: Trauma is a major health burden and a time-dependent critical emergency condition among developing and developed countries. In Asia, trauma has become a rapidly expanding epidemic and has spread out to many underdeveloped and developing countries through rapid urbanization and industrialization. Most casualties of severe trauma, which results in significant mortality and disability are assessed and transported by prehospital providers including physicians, professional providers, and volunteer providers. Trauma registries have been developed in mostly developed countries and measure care quality, process, and outcomes. In general, existing registries tend to focus on inhospital care rather than prehospital care. Methods: The Pan-Asia Trauma Outcomes Study (PATOS) was proposed in 2013 and initiated in November, 2015 in order to establish a collaborative standardized study to measure the capabilities, processes and outcomes of trauma care throughout Asia. The PATOS is an international, multicenter, and observational research network to collect trauma cases transported by emergency medical services (EMS) providers. Data are collected from the participating hospital emergency departments in various countries in Asia which receive trauma patients from EMS. Data variables collected include 1) injury epidemiologic factors, 2) EMS factors, 3) emergency department care factors, 4) hospital care factors, and 5) trauma system factors. The authors expect to achieve a sample size of 67,230 cases over the next 2 years of data collection to analyze the association between potential risks and outcomes of trauma. Conclusion: The PATOS network is expected to provide comparison of the trauma EMS systems and to benchmark best practice with participating communities.
