Authors' conclusion

Adding a collaborative care team to enhanced standard of care did not improve BP control but did improve patient ratings of chronic illness care.

Study context

Population
Adults with uncontrolled blood pressure (BP) and ≥1 other risk factors
Participants
1,820 adults
Comparison
CC/SC vs standard of care plus (SCP)
Primary endpoint
BP control (SBP ≤140 mm Hg, DBP ≤90 mm Hg) and patient activation
Follow-up
12 months
