Unattended automated office blood pressure (BP) measurement (u-AOBP) improves office BP measurement accuracy and reduces white-coat BP elevation, but there are reservations about its time efficiency in primary care. We used time-stamp methodology to measure u-AOBP procedure times performed without a rest period in 130 patients during routine clinic visits to three primary care clinics with 2.5-4.9 years u-AOBP experience. We documented the clinical activities of 30 medical assistants during the u-AOBP procedures. We also assessed MA and clinician satisfaction and knowledge about u-AOBP performance and interpretation. Median u-AOBP procedure time was <5 minutes, and MAs engaged in productive clinical activities during 83% of the procedures. Ninety-three percent of MAs and 100% of clinicians in the clinics agreed that u-AOBP is an efficient method to improve hypertension management. Barriers to effective u-AOBP implementation and ongoing utilization included initial difficulty incorporating u-AOBP into clinic workflow and medical staff knowledge deficiencies concerning correct u-AOBP performance and interpretation despite prior training and experience with the procedure. Intensive u-AOBP education and training programs are needed to facilitate effective u-AOBP implementation into primary care. The time required to perform u-AOBP can be utilized productively by staff.
