Study design and study population
We conducted a cross-sectional study of the research platforms of two
large academic institutions with a common EHR. The University of Miami
enterprise data environment and Vanderbilt University synthetic
derivative. Both contain a de-identified image of the EHR from
outpatient and inpatient encounters. The rationale for selecting both
institutions is the common EHR and our ongoing U54 research
collaboration that provided the framework to share de-identified data.
The study was approved by both the University of Miami and Vanderbilt
University IRB.
We identified from both institutions all primary care patients who had
at least one primary care visit between 2012 and 2017, calculated the
SCD score, and evaluated CV risk factors. To be included in the study,
patients needed to have the elements necessary to calculate the score
and have had no documented heart failure, coronary artery disease or
atrial fibrillation.
