To explore the feasibility of the nurse's prescription right in China, to develop the requirements for the qualification of the applicant for the prescription right of nurse, and to determine the content of certain prescriptions in the specifiCurrent literature on motor vehicle accidents (MVAs) has few reports regarding field factors that predict the degree of injury. Also, studies of mechanistic factors rarely consider concurrent predictive effects of on-scene patient physiology. The New Injury Severity Score (NISS) has previously been found to correlate with mortality, need for ICU admission, length of hospital stay, and functional recovery after trauma. To potentially increase future precision of trauma triage, we assessed how the NISS is associated with physiologic, demographic and mechanistic variables from the accident sitec circumstances.
