Summary

AIMS OF THE STUDY: Arterial hypertension is a major global health risk. Global surveys indicate that only half of patients with arterial hypertension receive pharmacotherapy, and only a quarter achieve the primary blood pressure target recommended by guidelines. This study aimed to evaluate the achievement of the primary blood pressure target in Swiss general practice, provide insights into arterial hypertension treatment, and identify factors associated with achieving this goal.

METHODS: This cross-sectional study utilised data from a large Swiss primary care database. Patients with arterial hypertension, aged ≥18 years, who underwent blood pressure monitoring in 2021 were included. The primary observation was blood pressure control, defined as the achievement of the primary blood pressure target of systolic blood pressure <140 mm Hg and diastolic blood pressure <90 mm Hg. Demographic data from physicians and patients, blood pressure measurements, comorbidities, cardiovascular risk factors, and pharmacotherapy were collected, and arterial hypertension stages were calculated. Unadjusted and multivariable-adjusted mixed logistic regression models were used to identify factors associated with blood pressure control.

RESULTS: A total of 49,290 patients were included, of whom 23,933 (48.6%) were female. The median patient age was 71 years (interquartile range 61–80). Blood pressure control was observed in 23,022 patients (46.7%), and 36,692 patients (74.4%) had an antihypertensive pharmacotherapy prescription. In multivariable analysis, blood pressure control was positively associated with arterial hypertension stage, antihypertensive pharmacotherapy, the intensity of blood pressure monitoring, and the number of blood pressure-increasing drugs, but negatively associated with a long-standing arterial hypertension, female sex, and old age.

CONCLUSIONS: While general practitioners appear to consider arterial hypertension stages in their treatment strategies, there is still room for improvement in arterial hypertension care by prescribing pharmacotherapy, especially in patients with long-standing arterial hypertension, female sex and old age.
