It was not activated by patients, but rather delivered to all patients in all intervention arms that the nurse interventionist was able to contact. bThe category “all patients” refers to the total number of enrolled patients who reported being African American or non-Hispanic white. This represents 573 of 591 total patients enrolled in the trial. cThree types of alerts could potentially be activated by patients with a subsequent attempt by a study nurse to deliver the appropriate interaction: intervention, which was triggered by out of control blood pressure; safety which was triggered by 2 consecutive BP readings > 175/105 or pulse < 40 or > 110; or praise, which triggered if patients had gone 6 months without triggering an intervention or safety alert, meaning BP was in control, and < 3 technical alerts. dTechnical alerts were activated by the patients when < 3 BP readings had been received by the system for their specified two week period or patient notified team they were having problems with equipment. These alerts were addressed by study research assistants rather than nurses.
