Many physician practices now utilize an electronic health record (EHR)
system that includes a secure messaging feature. Some of these
practices have extended their contact with patients by conducting
virtual visits between people with diabetes and nurses who are certified
diabetes educators. The remote technology includes the ability to
monitor blood glucose data to determine if these values are within goal
range. After six months, the results of the blood glucose levels for the
group participating in the virtual visits were evaluated.Which research
method was used?
