Effect of Patient Education
Patients enrolled in the PSM or PST groups receive
more extensive training and education than patients assigned
to usual care, which might explain the difference in
outcomes between the 2 groups. In the 2 studies that were
designed to explore the independent effect of patient education,
1 found no effect of patient education on time in
the therapeutic range (28, 29). The other did find a significant
effect on time in the therapeutic range when a
before–after within-group comparison was used, rather
than the more robust between-group comparison (41).
