Electronic health records are not a single system but a series of overlapping and legacy systems that require time and expertise to use efficiently.Commonly measured patient characteristics such as weight and body mass index are relatively easy to locate for most trial enrollees but less common characteristics, like ejection fraction, are not.Acquiring essential supplementary data-in this trial, state data on hospital admission-can be a lengthy and difficult process.

Keywords: clinical trial; electronic health record; heart failure; hospital admissions; pragmatic trial.
