Numerous trials show the benefit of implantable cardioverter-defibrillators (ICDs) for primary prevention in patients with low ejection fraction (EF), a class I indication. However, underutilization is well documented. We retrospectively reviewed charts to see whether placing a reminder statement into echocardiogram reports for appropriate patients increased adherence to guidelines. From January through June 2013, a brief reminder of the ICD guidelines was automatically inserted into echocardiogram reports with EF ≤ 35% (reminder period). Charts were reviewed to determine if these patients (1) were referred to Electrophysiology (EP) within 6 months of the index echo and (2) received an ICD within 6 months of EP referral. Chart review of all patients who had an echocardiogram performed between March and August 2012 with an EF ≤ 35% provided a control period. More patients were referred to EP in the reminder period compared with control period, 68% (54 of 80) versus 51% (53 of 104), p = 0.03. There was also a higher rate of discussions in the reminder period between patients and physicians about ICD therapy (71% vs 54%, p = 0.02). Among patients appropriate for ICD, 52% of patients during the reminder period received an ICD versus 38% of patients during the control period (p = 0.11). A simple reminder statement on echocardiography reports led to a significant improvement in appropriate EP referrals and a trend toward increased ICD implantation in appropriate patients.
