Hypothesis
This study aimed to establish the 12-month disability associated with each GBD 2010 injury health state and compare approaches to modeling the impact of multiple injury health states on disability.
Conclusion
The majority of patients survived with persisting disability at 12-months, highlighting the importance of improving estimates of non-fatal injury burden.
Supporting Evidence
- 46% of cases had a single injury health state.
- The additive and 'worst injury' models showed higher discrimination than the multiplicative model.
- 41.9% of the training dataset cases had recovered at 12 months.
Takeaway
After getting hurt, many people still have problems a year later, and we need to get better at understanding how injuries affect them.
Methodology
The study analyzed 12-month functional outcomes for 11,337 survivors using data from two trauma registries and evaluated three logistic regression models.
Potential Biases
The follow-up rate was 86%, and the outcomes of patients lost to follow-up are unknown.
Limitations
The study focused on severe and orthopedic injury cases, which may limit the generalizability of the findings.
Participant Demographics
The mean age was approximately 52.8 years, with 59.3% male and 40.7% female participants.
