Home Blood Pressure Measurements Are Not Performed According to Guidelines and Standardized Education Is Urgently Needed.

Background: Patient education is needed to perform home blood pressure measurement (HBPM) according to blood pressure (BP) guidelines. It is not known how BP is measured at home and what education is provided, which was the aim of the study.

Methods: Mixed-methods study among Australian adults who perform HBPM (June to December 2023). Participants completed a 30-item online survey on whether they followed guideline recommendations and the education they received for HBPM. Phone interviews were conducted among a purposive sample to further explore survey topics.

Results: Participants (n=350) were middle-aged (58±16 years; 54% women), and most (n=250, 71%) had hypertension. Guideline recommendations for HBPM were not always followed by survey participants. Most participants measured BP seated (n=316, 90%) with the cuff fitted to a bare arm (n=269, 77%). Only 15% measured BP in the morning and evening (n=54) and 26% averaged the BP readings over 7 days (n=90). Interview participants (n=34) described measuring BP at "different times of the day after doing different things." One-third of participants (n=112, 37%) received education for HBPM, which interview participants described as vague verbal instructions from health care practitioners. Participants who received education did not perform high-quality HBPM. Participants who did not receive education mimicked BP measurement methods of health care practitioners, "I do it the way I've seen them do it."

Conclusions: HBPM is not performed according to guideline recommendations, and adults who received ad hoc education did not perform high-quality HBPM. These findings highlight a need for effective education to support HBPM for clinical decision-making.
