[Is the action taken by Catalonian primary care doctors adequate in view of the insufficient reduction in blood pressure levels in hypertensive patients? DISEHTAC-2001 study].
OBJECTIVE
To determine the attitude to therapy of primary care staff in view of the lack of reduction in blood pressure. To describe the most commonly used antihypertensives.


METHODS
Descriptive, longitudinal, retrospective study during the year 2001.


METHODS
Primary care, Spain.


METHODS
We analysed 990 hypertensive patients from 12 health centres picked from the 31 participants in the DISEHTAC-1996 study.


METHODS
Age, sex, weight, and height were analysed, along with blood pressure values throughout the year 2001, therapeutic attitude (increase/replacement/combination) with poor control (more than 2 consecutive visits with blood pressure>139 and/or 89 mm Hg), screening and prevalence of cardiovascular risk factors (CVRF), and drugs used.


RESULTS
There were 58.9% females; mean age: 65.4 (13.01) years, and 43.8% received 2 or more antihypertensives. The most common antihypertensives prescribed were diuretics (47.6%), and angiotensin-converting enzyme (ACE) inhibitors plus diuretics was the most used combination (22.1%). When there was poor control, some change in treatment was made in 76.8% (95% confidence interval [CI], 73.6-80) of cases. The most common was a combination of drugs (49.6%). The expected action was more frequent in those over 65 years and with a grade I of arterial hypertension (systolic blood pressure [SBP] between 140-150 and diastolic blood pressure [DBP] between 90-99 mm Hg (P<.001).


CONCLUSIONS
Combined therapy is used in almost half of hypertensive patients, with the most common action being a drug combination.
