SMS-facilitated home blood pressure monitoring: A qualitative analysis of resultant health behavior change.

This was a secondary qualitative analysis of exit interviews from a pilot; it did not show whether BP fell or whether behavior changes lasted. Only forty of forty-three enrolled patients were interviewed; three had withdrawn and could not be reached, so the views of those who dropped out are missing. The interview was designed for both quantitative and qualitative data and used some closed questions, which may have narrowed participant conversations. The study did not stop at data saturation; it interviewed all willing participants, and only one interview per participant was done. Participants used the program for six weeks, so longer-term benefits or frustrations with home BP monitoring were not examined. The program included video education, automated text prompts, personalized BP reports, and a confirmation call, so the contribution of any single component cannot be separated.

The authors declared no conflicts of interest. The article is listed as NIH extramural research support.

Do not conclude that MyBP lowered blood pressure or caused lasting behavior change. This was a small qualitative pilot without objective BP outcome testing, and it combined video education, text prompts, personalized reports, and a confirmation call, so the contribution of any single component cannot be separated.
