Objective: According to the published studies general practitioners were aware of the current care guidelines and their attitude towards hypertension treatment was positive. We determined among Finnish general practitioners the awareness of the Finnish current care hypertension guidelines and the trigger values to intensify the antihypertensive medication. Methods: One hundred general practitioners working in health centers in Finland were randomly selected for this study. Sixty-eight of them answered the questionnaire which was collected electronically through e-mail. In the first part of the questionnaire, the self-reported awareness of the guidelines (not aware, aware or familiar with) was asked. In the second part, the trigger value for intensifying the antihypertensive treatment in three different groups of hypertensive patients was questioned. Results: Participants were aware of the original year 2002 hypertension guidelines and the succeeding hypertension guideline updates. Despite, two thirds of the participants reported higher trigger blood pressure (BP) value for intensifying the antihypertensive treatment compared to those given in the guidelines. High BP limit policy was most often adopted in the treatment of patients with low-risk hypertension. On the contrary, in the treatment of patients with high BP and non-complicated diabetes, systolic BP trigger value exceeding the guideline values was reported as often as an equal or even BP value below the one stated in the guidelines. In patients with BP and complicated diabetes most physicians reported higher trigger values than stated in the guidelines. Conclusions: This study suggests that clinicians overestimate their adherence to hypertension guidelines as seen also in one earlier study. The BP trigger values to intensify antihypertensive medication were higher than suggested in current care guidelines. In most former studies the clinicians had only been asked for the adherence. In this study the adherence is assured by asking also the trigger values to intensify antihypertensive treatment. The results concerning the trigger values will be compared with the reported adherence.
