BACKGROUND Although trauma centers represent an integral part of healthcare in the US, characterization of their financial vulnerability has not been reported. We sought to characterize the financial health and vulnerability among California trauma centers and identify factors associated with high and low vulnerability. STUDY DESIGN The RAND Hospital Data financial dataset was used to evaluate all American College of Surgeons (ACS)-verified trauma centers in California. Financial vulnerability of each center was calculated using 6 metrics to calculate a composite Financial Vulnerability Score (FVS). Tertiles of the FVS were generated to classify trauma centers as high, medium, or low financial vulnerability. Hospital characteristics were also analyzed and compared. RESULTS Forty-seven ACS trauma centers were identified. Nine were Level I, 27 were Level II, and 8 were Level III. Level I centers encompassed the greatest proportion of the high FVS tier (44%), whereas Level II and III centers were the most likely to be in the middle and lower tiers, respectively (44%; 63%). Lower FVS centers had greater asset:liability ratios, operating margins, and days cash on hand compared with the 2 higher tiers, whereas high FVS centers showed a greater proportion of uncompensated care, outpatient share rates, outpatient surgeries, and longer days in net accounts. Lower FVS centers were more likely to be teaching hospitals and members of a larger corporate entity. CONCLUSION Many ACS trauma centers are at moderate/high risk for financial vulnerability and disparate impacts of stressor events, and the FVS may represent a novel metric that could be used at the local or statewide level.
