Official title
Clinical Landscape of Epidemiology and Assessment of Results in Hypertension
Overview
This is a retrospective observational cohort study based on secondary use of routinely collected electronic health data. The design was selected to enable population-level characterisation of treatment patterns and clinical inertia (both diagnostic and therapeutic) in the management of hypertension across diverse settings in Brazil's public primary care system (SUS).
Detailed description
This is a retrospective observational cohort study based on secondary use of routinely collected electronic health data. The design was selected to enable population-level characterisation of treatment patterns and clinical inertia (both diagnostic and therapeutic) in the management of hypertension across diverse settings in Brazil's public primary care system (SUS).
The retrospective cohort design allows for efficient use of existing clinical data to evaluate real-world practice against national guideline recommendations. The primary outcomes relate to treatment decisions and delays rather than interventional effects; therefore, an observational design is methodologically appropriate and ethically preferable.
The study will be conducted across 05 Brazilian municipalities participating in the epHealth Primary Care Solutions platform. These municipalities span multiple regions and reflect heterogeneity in socio-demographic context, healthcare infrastructure, and epidemiological profiles.
Primary outcome measures
- Uncontrolled blood pressure [Time frame: through study completion, an average of 1 year]
Secondary outcome measures (2)
- Antihypertensive treatment [Time frame: through study completion, an average of 1 year]
- Risk stratification [Time frame: through study completion, an average of 1 year]
Eligibility criteria
Inclusion criteria
- Age ≥18 years at the time of Hypertension diagnosis
