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?
