Study ending of hospitalized traffic accidents injured in Urmia Imam Khomeini hospital by using TRISS method

Aims: One of the most common events is traffic accidents. Road accidents are the second death cause and age loss in the country. The aim of this study was to determine the survival rate of traffic accident victims and assessing the quality of hospital care in Imam Khomeini Hospital, Urmia by using TRISS method. Instruments and Methods: This cross sectional study was performed on 760 accident victims hospitalized to Imam Khomeini Hospital of Urmia in 2017; they were selected purposefully. Respiratory rate, systolic blood pressure, Glasgow coma scale (GCS), and the severity of injuries of the patient were collected based on the relevant expert report, and using the TRISS software, the probability of survival for patients were calculated. Z and W static were used to compare survival probability. Findings: The number of male injured individuals were 562 (73.9%) and female were 198 (26.1%). 74 (9.7%) injured individuals were between 0 and 14 years old, 437 (57.5%) individuals were between 15 and 54 years old, and 249 (32.7%) individuals were over 54 years old. The mean of RTS was 7.67±0.55 and 6.00±1.57 for the survived and non-survived individuals, respectively. The mean of the ISS was 21.62±17.63 and 56.32±25.02 for the survived and non-survived individuals, respectively. Also, the expected death was 60, and the observed death was 69. Conclusion: The number of observed deaths is more than the expected ones, indicating the low quality of hospital care.
