Barriers to blood pressure control: a STITCH substudy.

Area of Science:

• Cardiology
• Hypertension Management
• Clinical Research

Background:

• Despite advances, achieving target blood pressure (BP) remains a challenge for many patients.
• The specific factors contributing to inadequate BP control are not fully understood.

Purpose of the Study:

• To conduct a post hoc analysis identifying key determinants of poor BP control in patients with uncontrolled hypertension.
• To investigate the impact of antihypertensive therapy intensification and patient comorbidities on BP outcomes.

Main Methods:

• Analysis of data from 2030 patients with uncontrolled hypertension across 45 general practices.
• Documentation of antihypertensive medication changes and BP measurements over a 6-month follow-up.
• Multivariate analysis to identify predictors of BP reduction, including patient demographics and comorbidities like diabetes.

Main Results:

• 42% of patients failed to achieve target BP control within 6 months.
• Failure to intensify antihypertensive therapy was a significant predictor of poorer BP reduction.
• Patients with diabetes were less likely to reach BP targets (26%) compared to those without (64%).
• Therapy intensification was insufficient, with only 25% of patients not at target receiving ≥3 drugs.

Conclusions:

• Inadequate BP control in hypertensive patients, with or without diabetes, is partly due to a failure to intensify antihypertensive therapy.
• Clinical inertia, or resistance to increasing medication intensity, represents a significant barrier to achieving optimal BP management.
