Insights
Predicting inpatient mortality in pediatric blunt trauma is crucial. The study found that the International Classification of Disease, Ninth Revision-based Injury Severity Score (ICISS), Glasgow Coma Scale (GCS) motor response, and AVPU score best predict outcomes.
Area of Science:
- Pediatric trauma care
- Injury severity assessment
- Mortality prediction modeling
Background:
- Pediatric blunt trauma is a significant cause of mortality.
- Existing trauma scores may not fully capture mortality risk in pediatric blunt trauma.
- Accurate prediction of inpatient mortality is essential for resource allocation and patient management.
Purpose of the Study:
- To identify independent predictors of inpatient mortality in pediatric blunt trauma patients.
- To develop a predictive formula for inpatient mortality probability in this population.
Main Methods:
- Utilized data from 2,923 pediatric blunt trauma patients in the New York State Trauma Registry (1994-1995).
- Employed stepwise logistic regression with survival status as the dependent variable.
- Included variables from Pediatric Trauma Score (PTS), Revised Trauma Score (RTS), Glasgow Coma Scale (GCS), AVPU score, and injury severity measures (ISS, ICISS).
Main Results:
- The International Classification of Disease, Ninth Revision-based Injury Severity Score (ICISS), GCS motor response (no motor response = 1), and AVPU score (unresponsive) were significant independent predictors.
- The predictive model demonstrated excellent fit (C statistic = .964).
- High sensitivity (.944) and specificity (.926) were achieved in predicting inpatient mortality.
Conclusions:
- ICISS, GCS motor response, and AVPU score are superior independent predictors of inpatient mortality in pediatric blunt trauma.
- These key predictors are not fully incorporated into standard trauma scores like PTS and RTS.
- The findings can inform more accurate mortality risk assessment for pediatric trauma patients.
Purpose:
The aim of this study was to identify significant independent predictors of inpatient mortality rates for pediatric victims of blunt trauma and to develop a formula for predicting the probability of inpatient mortality for these patients.
Methods:
Emergency department and inpatient data from 2,923 pediatric victims of blunt injury in the New York State Trauma Registry in 1994 and 1995 were used to explore the relationship between patient risk factors and mortality rate. A stepwise logistic regression model with P<.05 was developed using survival status asthe dependent variable. Independent variables included are elements of the Pediatric Trauma Score (PTS), additional elements from the Revised Trauma Score (RTS), the motor response and eye opening components of the Glasgow Coma Scale (GCS), age-specific systolic blood pressure, the AVPU score, and 2 measures of anatomic injury severity (the Injury Severity Score [ISS] and the International Classification of Disease, Ninth Revision-based Injury Severity Score [ICISS]).
Results:
The only significant independent predictors of severity that emerged were the ICISS, no motor response (best motor response = 1) from the GCS, and the unresponsive component from the AVPU score. The statistical model exhibited an excellent fit (C statistic = .964). The specificity associated with the prediction of inpatient mortality rate based on the presence of 1 or more of these risk factors was .926, and the sensitivity was .944.
Conclusion:
The best independent predictors of inpatient mortality rate for pediatric trauma patients with blunt injuries include variables not specifically contained in the PTS or the RTS: ICISS, no motor response (best motor response = 1) from the GCS, and the unresponsive component of the AVPU score.
