Automated MEdical Record Driven Implantable CArdioverter-defibrillator

Status Terminated

Clinical Trial Summary

Purpose and Objective: Heart failure therapies including beta-blockers, ACE-inhibitors, aldosterone antagonists, implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy (CRT) devices have proven beneficial but are underused in eligible patients. The investigators seek to determine if automating referral to cardiologists and electrophysiologists through an intelligent electronic medical record system can improve adherence to American College of Cardiology (ACC)/ American Heart Association (AHA) heart failure guideline recommended therapies.

Study activities and population group: The AMERICA-HF trial will be a randomized, single-center, single blinded study comparing standard-practice provider initiated cardiovascular specialty referral to experimental automated medical record driven cardiovascular specialty referral. An investigational program will automatically screen all finalized electronic reports from clinically indicated transthoracic echocardiogram studies performed in the Duke University Echo Lab system and create an automated query to obtain HF ICD-9 codes. Eligible patients will be randomly assigned to participate in a registry (n=125) or automated electronic medical record (EMR) based subspecialty care intervention arm (n=125).

Data analysis: The primary endpoint is rate of adherence (%) to ACC/AHA HF guideline recommended therapies at 3, 6, and 12 month follow-up among patients randomized to the registry compared to the intervention. Differences in characteristics (including use of guideline recommended therapies) will be tested using Pearson Chi-square tests for categorical variables and Wilcoxon two-sample tests for continuous variables. Time to event analysis will be performed for the secondary endpoints of hospitalization or death.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
