Insights
The introduction of a trauma admitting service (TAS) at Christchurch Hospital did not improve major trauma patient outcomes, including mortality and hospital stay. Further research with better resources is needed.
Area of Science:
- Trauma Care
- Emergency Medicine
- Public Health
Background:
- Major trauma is a leading cause of death for young adults in New Zealand.
- Specialized trauma care, including dedicated admitting teams, is associated with improved patient outcomes.
- Christchurch Hospital implemented a minimally resourced trauma admitting service (TAS) in January 2022.
Purpose of the Study:
- To evaluate the impact of a trauma admitting service (TAS) on the outcomes of major trauma patients at Christchurch Hospital.
Main Methods:
- A pre-post cohort study design was employed.
- Major trauma patient outcomes were compared one year before and after TAS implementation.
- Patient characteristics, hospital length of stay (LOS), in-hospital mortality, 30-day mortality, and tertiary survey completion were analyzed.
Main Results:
- The study included 773 major trauma patients (356 pre-TAS, 417 post-TAS).
- No significant differences were observed in hospital LOS (7 vs 8 days), in-hospital mortality (6% vs 7%), 30-day mortality (6% vs 7%), or tertiary survey completion (60% vs 60%) between the pre- and post-TAS groups.
- Patient characteristics were similar across both cohorts.
Conclusions:
- The implementation of the TAS at Christchurch Hospital did not result in objective improvements in major trauma patient outcomes.
- Potential limitations in service coverage and staffing may have affected the TAS's effectiveness.
- Further investigation with enhanced resources and larger patient cohorts is recommended to fully assess the impact of trauma admitting services.
Aims:
Injury is the leading cause of death for those under 35 years in New Zealand, with major trauma (Injury Severity Score >12) accounting for 2,409 cases in 2021/2022. There is evidence of improved outcomes with specialised trauma care including dedicated trauma admitting teams. Christchurch Hospital introduced a minimally resourced trauma admitting service (TAS) in January 2022. This study evaluates the impact of the implementation of a TAS on the outcomes of major trauma patients.
Methods:
A pre-post cohort study compared major trauma patient outcomes at Christchurch Hospital 1 year before and after TAS implementation.
Results:
The study included 773 patients-356 pre-TAS and 417 post-TAS. Patient characteristics were similar across both cohorts. No significant differences were found between pre- and post-TAS groups in hospital LOS (7 vs 8 days, p=0.558), in-hospital mortality (6% vs 7%, p=0.774), 30-day mortality (6% vs 7%, p=0.764) or tertiary survey completion (60% vs 60%, p=0.853).
Conclusion:
The introduction of the TAS at Christchurch Hospital did not yield objective improvements in major trauma outcomes. Limitations in coverage and staffing may have impacted effectiveness, highlighting the need for better resources and larger studies for further analysis.
