Impact of Social Determinants on Trauma Outcomes

Publication Title: The unrecognized burden of patient-level social determinants of health on health outcomes following traumatic injury

Summary

Question
This study examined the impact of patient-level social determinants of health (SDOH) on health outcomes following traumatic injury. The researchers aimed to identify specific SDOH factors, such as financial concerns, language barriers, and psychiatric history, that might predict adverse outcomes, including mortality, complications, and longer hospital stays.
Why it Matters
Traumatic injuries are a leading cause of death and carry a significant societal and economic burden. While social determinants of health—such as financial insecurity and housing instability—are known to influence outcomes, their effects have often been studied using generalized, location-based data. This research highlights the importance of assessing SDOH at the individual patient level to better predict and address health disparities in trauma care. Understanding these factors could improve post-injury care, reduce complications, and lower healthcare costs.
Methods
The study analyzed data from 868 trauma patients admitted to a large urban Level I trauma center between 2019 and 2020. Researchers combined social work interview data with trauma admission records to assess SDOH factors like financial concerns, housing insecurity, alcohol use, and psychiatric history. Multivariable analysis was used to evaluate how these factors were associated with outcomes, including mortality, complications, hospital length of stay (LOS), and discharge location.
Key Findings
Financial concerns were the most common SDOH, reported by 33.4% of patients. Patients requiring a language interpreter had five times the odds of in-hospital mortality and three times the odds of major complications. Psychiatric history and alcohol use were linked to increased complications, while alcohol use also predicted longer hospital stays. Black race and male sex were associated with extended LOS. Severe injuries, as measured by standardized scores, also correlated with higher risks of complications and longer recovery times.
Implications
The findings suggest that patient-level SDOH, such as financial instability and language barriers, are critical predictors of adverse trauma outcomes. Addressing these factors during hospitalization could reduce complications and mortality. For instance, early identification of social barriers might improve discharge planning and recovery. The results also highlight the need for trauma care systems to integrate social risk assessments into standard care practices.
Next Steps
Future research should focus on understanding the mechanisms by which SDOH influence trauma outcomes. Additionally, studies are needed to evaluate whether targeted interventions, such as enhanced social support or improved access to interpreters, can mitigate these effects. Expanding this research to other trauma centers could validate the findings and identify broader trends.
