BACKGROUND: Traffic accidents account substantially for @entity717 and deaths in the modern world. Whether @entity955 complicates the outcome of @entity130 remains under-investigated. METHODS: From 1998 to 2010, all inpatient records stored in the Taiwan National Health Insurance database were screened. Those related with traffic accidents were aggregated to individuals and enrolled. The medical expenses and hospital outcomes were compared between @entity1 with @entity955 (AF group) and either the rest @entity1 (No-AF group) or the propensity-matched @entity1 without @entity955 (No-AF-matched group). Prognostic predictive variables for adverse in-hospital events were further identified by multivariate regression analysis. RESULTS: Within the 13-year time span, of the 776,620 individuals ever admitted for traffic accidents, there were 1233 @entity1 with AF. Compared with No-AF and No-AF-matched groups respectively, AF @entity1 stayed longer in hospital (10.9  10.6 vs. 6.8  7.2 and vs. 8.2  8.7days, both p<0.001), more often required surgical operations (73.2% vs. 69.5%, p=0.006 and vs. 68.9%, p=0.021), and consumed larger medical expenses (US  2384  3174 vs. 1246  2024, or 91.3% higher; and vs. 1406  2172, or 69.6% higher, both p<0.001), yet developed more @entity260 (8.8% vs. 1.2% and vs. 3.2%, both p<0.001) and deaths (2.5% vs. 0.9%, p<0.001 and vs. 1.6%, p=0.015). Identified by regression analysis, CHA2DS2-VASC score and representative demographic/injury-related variables predict in-hospital adverse events in these AF group @entity1 . CONCLUSIONS: For @entity1 suffering traffic accidents, those with AF consume more surgical resources and medical expenses yet end up with poorer hospital outcome, especially those with higher CHA2DS2-VASC scores and other relevant variables.
