Background: As the United States medical system transitions to value-based reimbursement, interested parties will increase scrutiny in testing that may not alter management or outcomes. We investigated whether transesophageal echocardiography (TEE) provokes treatment alteration across age strata in hospitalized patients undergoing a TIA/stroke work-up. Methods: Consecutive patients admitted to the Mayo Clinic Arizona healthcare system between 1/1/2010 and 2/9/2015 were evaluated. A total of 832 patients were identified of which 314 were excluded primarily due to the fact that the TEE was performed as an outpatient. Therefore, 518 subjects (mean age = 68.2 +/- 14.1 y, 42.5% female) were included. A change in treatment was defined a priori as: anticoagulation (AC) initiated for atrial fibrillation found on TEE only (i.e. not identified on telemetry), complex proximal aortic arch plaque, left atrial or left atrial appendage thrombus, intracardiac mass, intracardiac shunt (atrial septal defect (ASD)/ patent foramen ovale (PFO)) ; PFO closure; cardiac mass removal; valve replacement for endocarditis; antibiotics for endocarditis. Results: See Tables A & B Conclusion: TEE in the evaluation of hospitalized patients with TIA/stroke resulted in a change in treatment in approximately 7% of patients regardless of age. Many of the decisions to change treatment were judgment-based and therefore adoption of the routine use of TEE in all patients with TIA/stroke is dependent on institutional practice standards.
