To test an electronic Patient-Reported Outcomes Measure (e-PROM) intended to assess patients' daily perceptions of symptoms and wellbeing, as well as self-measured blood pressure, treatment side-effects and medicine intake;

• Explore patient interactions (learning and understanding) with an internet-reporting system providing structured feedback of e-PROM results to examine if such feedback is useful in improving adherence;
• Explore patient-physician/nurse interactions to examine if structured feedback of e-PROM results serves as a useful complement to support consultations regarding treatment monitoring and adherence.

Adherence to antihypertensive medication will be checked through a question in the cell phone and evaluation of patient´s use of antihypertensive medication will be checked from the National Prescribed Drug Register of drugs. Twenty patient-physician/nurse consultations will be audio/video-recorded at regularly scheduled appointments to obtain authentic evidence of the use of the self-reports in clinical practice. The outcomes will include blood pressure measurement, registration of self-reported symptoms and discourse analyses.
