Background: Prehospital scores are used for determining the prognosis of trauma severity in trauma patients. Objectives: This study aimed at
developing a new prehospital score for emergency medical service (EMS) staff to predict hospitalization in trauma patients transferred to the
hospital. Patients and Methods: This study was a diagnostic test evaluation conducted on data of 1185 traumatic patients transferred through
EMS to Poursina Hospital of Rasht between March 2012 and March 2013. Data were collected using a questionnaire with two parts. The first
part included data on demography, injury, and type of interventions performed at the scene of the accident. The second part consisted of initial
evaluations (Glasgow coma scale (GCS), oxygen saturation (O2S), pulse rate (PR), systolic blood pressure (SBP), the ability to walk, and
outcome (hospitalization, nonhospitalization). The questionnaire was filled out by EMS staff at the scene or during transfer to the hospital with
respect to clinical observations. Data were analyzed using the logistic regression model. The Hosmer–Lemeshow test was also used to examine
the good fit of model. Results: A total of 1185 patients were evaluated using prehospital data. Of seven variables evaluated by the scoring
system, only four variables were identified in the regression analysis as predictors of hospitalization including age, SBP, O2S, and walking
ability. Sensitivity, specificity, and positive and negative likelihood ratios were 0.67, 0.68, 2.09, and 0.48, respectively. Conclusions: The
GOMAAPS (GCS, O2S, mechanism of injury, age, ability to walk, PR, and SBP) score serves as a guide for the EMS staff at the scene to be
understood of the necessity of transfer and predicting hospitalization.
