Background. Various cardiac dysrhythmias such as supraventricular and ventricular premature beats, supraventricular and ventricular paroxysmal tachycardia, atrial and ventricular fibrillation and atrial flutter have been reported, in case series, as complications of blunt cardiac and thoracic trauma. The objective of this research was to determine whether thoracic or blunt cardiac injury is associated with cardiac dysrhythmia in a large multi-state hospitalized population. Methods. Cases and matched (by age) controls were identified based on hospital discharge information that was collected from 986 acute general hospitals across 33 states in 2001. Both the exposure (thoracic trauma and blunt cardiac injury) and the outcome (cardiac dysrhythmias) were identified based on ICD-9-CM discharge diagnoses. Unadjusted and conditional adjusted (for gender, race, length of stay and primary source of payment) multivariate logistic regression analyses were performed. Results. After adjusting for potential confounders, patients 50 years and younger diagnosed with blunt cardiac injury had 4-fold [95% confidence interval (CI), 1.40; 11.60] increase in the risk of cardiac dysrhythmia. Independent of potential confounding factors, discharge for blunt cardiac injury among patients 51 to 70 years was associated with a 2-fold [95% CI, 1.36-3.82] increased risk for cardiac dysrhythmia. Conclusion. Blunt cardiac injury was found to be a significant risk factor for cardiac dysrhythmia. Longitudinal studies are needed to better establish the association between trauma and cardiac dysrhythmias.

Learning Objectives:

• Identify the possibility of the link between trauma and cardiac dysrhythmias
• Identify how ICD-9-CM is used in hospital discharge data
• Recognize the possibility of a matched case-control design using the National Inpatient Sample (NIS) dataset
