Abstract Background Home Blood Pressure Telemonitoring (HBPT) has been proposed to improve drug adherence, blood pressure control, and efficient care delivery in patients with hypertension. Its adoption in GP practices however remains low. In this pilot study we evaluated barriers and facilitators for successful implementation, patient satisfaction, clinical effectiveness, and efficiency for a HBPT project in Dutch GP practices by means of the Quadruple Aim Model. Methods GP practices included patients with hypertension that were part of their regular cardiovascular disease program. We conducted semi-structured interviews at 3- and 6-months to identify barriers and facilitators for successful implementation. Patient satisfaction was measured with Telehealth Usability (TUQ)—and Mhealth App Usability (MAUQ) Questionnaires. A SPRINT-protocol blood pressure measurement was performed after the pilot project to assess clinical effectiveness. Efficiency data were collected on the number of registered consultations and practice measurements performed during the 6-month project. Results Three GP practices included 19 patients. Barriers for implementation were a lack of a reimbursement structure, lack of information technology (IT) system integration and increased experienced workload when using HBPT. Facilitators included the positive effects on blood pressure control, increased sense of safety for patient and care provider, and increased disease-insight. Median satisfaction scores for TUQ and MAUQ questionnaires (scale 1–7) were 6 (IQR 5–6) and 6 (IQR 5–7). At baseline, 16% of the patients had a blood pressure < 140/90 mmHg. Based on the performed SPRINT measurements, 68% had a well-controlled blood pressure (< 140/90 mmHg) after 6 months. Average blood pressure improved from 151/89 mmHg to 132/81 mmHg ( p = < 0.05). On average, one monthly contact moment related to hypertension between patient and GP practice was registered. Conclusions We found positive results following the introduction of HBPT in GP ...
