Abstract

BACKGROUND: Motor vehicle crashes (MVCs) are one of the leading causes of death in the nation and in New York State, particularly among younger adult males. It is important to study how to reduce mortality from MVCs. METHODS: Hospitalized victims of motor vehicle crashes in the 1994-1995 New York State Trauma Registry were identified for the study. A statistical model was used to calculate risk-adjusted mortality rates for groups of hospitals constituting each level of care (regional trauma center, area trauma center, noncenter). Levels of care were also compared with respect to the location of deaths in the hospital (emergency department, inpatient), and the time between emergency department admission and death for patients dying in the hospital. RESULTS: The risk-adjusted mortality rate for MVCs in patients in regional centers was higher, although not significantly higher (6.91%; 95% confidence interval [CI], 6.18%-7.70%) than for area centers (5.53%; 95% CI, 4.43%-6.82%) or for noncenters (5.83%; 95% CI, 4.70%-7.15%). However, regional centers admitted seriously injured trauma patients from the emergency department much more quickly than other levels of care. Whereas only 18% of all in-hospital deaths occurred in emergency departments of regional centers, the comparable percentages for area centers and noncenters were 39% and 46%, respectively. Also, 43% of all deaths in regional centers occurred within 24 hours of presentation to the emergency department, compared with 15% in area centers and 21% in noncenters. CONCLUSION: Risk-adjusted inpatient mortality rates for victims of MVCs may not yield a fair comparison of performance for different levels of care or for different hospitals because of differences in how quickly emergency department patients are admitted to the hospital. A more equitable way to assess hospital mortality rates may be to include emergency department deaths in addition to inpatient deaths.
