Introduction: We tested the hypothesis that shared decision making (SDM) results in higher involvement of patients in blood pressure therapy.

Methods: The intervention group consisted of 15 physicians in primary care seeing 62 hypertensive patients (control group: 59 hypertensive patients). All 121 patients were enrolled in a patient education programme (J. Human Hypert. 2004). The 15 study physicians took part in a specially designed SDM-communication training. In the intervention group 6 SDM-consultations took place within two years. Changes of blood pressure were assessed in self- and physicians´ measurements. Questionnaires about the autonomy preference (API), the SDM process (COMRADE, IPM-score), quality of life (SF-36), health habits and life-style changes were analysed.

Results: In the intervention group a significant increase in SDM as judged by the patients could be assessed, but also in the control group there was some increase (changes from baseline: p<0.0001 and control p<0.01) pointing to a "carry-over effect".

After one year the fall in blood pressure within the intervention group was significant, in contrast to the control group (-9.9+10mm Hg /-3.5+11mm Hg, p=0.0005 /p<0.0001 and -5.91+12mm Hg/-3.0+8.77mm Hg, p=0.33/p=0.08). Of note, significantly more antihypertensive drugs were taken in the intervention group (p=0.013), but there were no significant life-style changes (sports, food, weight reduction) in both groups.

Conclusion: The concept of SDM could be implemented in daily practice of primary care physicians. As a consequence the adherence to drug treatment increased in the study group resulting in a significant blood pressure decrease after one year.
