Irina Vasilyeva, Moscow, Russia Russian National Research Medical University Clinical and Research Institute of Emergency Children’s Surgery and Trauma Modern health care in children's traumatology is directed to: Prevention of trauma causes Timely rendering of medical care Objective assessment of trauma severity for treating patients with trauma Effective decision-making to select an adequate tactics of treatment Justified distribution of resources in a medical institution

Irina Vasilyeva, Moscow, Russia Russian National Research Medical University Clinical and Research Institute of Emergency Children’s Surgery and Trauma Objective estimation of trauma severity is based on: objective estimation of injury severity objective estimation of patient’s state after trauma. This estimation has been done using ISS-RTS-TRISS (Boyd and colleagues in 1987), APACHE II (Knaus et al., 1985) and other scales. These scales allow to have an objective understanding of patient’s state severity and to find out an expected risk for death outcome

Irina Vasilyeva, Moscow, Russia Russian National Research Medical University Clinical and Research Institute of Emergency Children’s Surgery and Trauma Prognostic scales also allow: to sort patients by injury severity to prescribe an adequate medical treatment for trauma patients to define the tactics of medical care for such patients

Irina Vasilyeva, Moscow, Russia Russian National Research Medical University Clinical and Research Institute of Emergency Children’s Surgery and Trauma Research Goal: To study the effectiveness of these scales in supporting doctor’s decision while choosing tactics for treating children with severe mechanical trauma and to study a possibility to integrate the studied methodology into Hospital Information System MEDIALOG

Irina Vasilyeva, Moscow, Russia Russian National Research Medical University Clinical and Research Institute of Emergency Children’s Surgery and Trauma Conclusion The automated calculation of scale parameters in Health Informatics System (HIS) has shown that the discussed technique is a quick and operative instrument for supporting clinical decision so as to reduce death outcomes in children with trauma. Our research has shown that ISS-RTS-TRISS prognostic scale has an outstanding discrimination ability and a significant calibration ability which can be used for prognostic assessment of outcomes in children with trauma. In spite of the fact that these APACHE II prognostic scale has shown an excellent discrimination ability, the calibration ability was not significant. Thus, ISS-RTS-TRISS scale can be recommended for assessing severity of injuries in children
