Hypertension case finding in primary care- A Practical NHS Pathway

15th December 2025

Hypertension remains one of the most common and preventable causes of cardiovascular disease in England. Despite clear guidance and effective treatments, an estimated 30 percent of adults with hypertension remain undiagnosed, leaving many people at avoidable risk of heart attack, stroke, and long-term complications.

Hypertension case finding in primary care exists to close this gap. It brings together general practice, Primary Care Networks (PCNs), and community pharmacy to identify people earlier, confirm diagnosis accurately, and intervene before harm occurs.

However, screening alone does not improve outcomes. Hypertension case finding only delivers value when primary care owns a clear, end-to-end pathway that consistently converts blood pressure checks into diagnosis, optimisation, and sustained control.

This article outlines a practical, NHS-aligned approach to hypertension case finding in primary care, with a focus on governance, workforce, and measurable outcomes.

Key takeaways

• Hypertension case finding is a primary care pathway, not a standalone screening activity
• Community pharmacies expand access, but diagnosis and optimisation remain the responsibility of primary care
• NICE NG136 confirmation thresholds must be embedded using ambulatory or home monitoring
• The biggest risk is not missing raised blood pressure, but failing to act on it consistently
• PCNs that build structured follow-up and medicines optimisation into pathways achieve better outcomes, not just higher detection rates

What hypertension case finding means in primary care

In primary care, hypertension case finding refers to the proactive identification of people with undiagnosed high blood pressure, followed by structured confirmation, diagnosis, treatment, and review.

This approach goes beyond opportunistic readings. Effective pathways ensure that raised blood pressure leads to timely confirmation, accurate coding, and treatment initiation. In practice, this forms a hypertension pathway primary care teams can rely on rather than a series of disconnected activities.

While multiple settings contribute to detection, primary care retains clinical accountability for diagnosis, prescribing, and long-term management. Without this ownership, blood pressure case finding risks becoming an activity measure rather than a population health intervention.

This pathway-led approach underpins wider hypertension management and aligns with how practices approach hypertension case finding in primary care.

The role of community pharmacy

The NHS Community Pharmacy Blood Pressure Check Service has expanded access to blood pressure checks, particularly for people who rarely attend routine GP appointments.

Community pharmacies support hypertension case finding by providing accessible blood pressure checks, identifying raised readings, and, where appropriate, offering ambulatory blood pressure monitoring. Their role is to extend reach and capacity, feeding timely information back into primary care–led pathways rather than operating as an alternative to them.

For practices and PCNs, pharmacies act as capacity multipliers rather than replacements. When integrated into a clearly defined pathway, they improve access and reduce pressure on appointments. Where pathways and ownership are unclear, they can unintentionally increase administrative burden and clinical risk.

Primary care retains responsibility for confirmation, diagnosis, and ongoing management, in line with NICE Hypertension in adults guideline (NG136), which sets expectations for diagnostic thresholds, monitoring, and treatment optimisation.

Confirmation and diagnosis – embedding NICE NG136

NICE NG136 provides a clear framework for confirming hypertension, yet this remains one of the most common failure points.

These confirmation steps are defined in NICE NG136 hypertension guidance and should be embedded consistently across primary care pathways.

Getting this stage right is fundamental to safe and timely hypertension diagnosis primary care, particularly where multiple clinicians and settings are involved in confirmation and follow-up.

Key principles include:

• Clinic readings of 140/90 mmHg or higher require confirmation
• Ambulatory blood pressure monitoring ABPM is the preferred diagnostic method
• Home blood pressure monitoring HBPM is appropriate when ABPM is unsuitable
• Diagnosis is confirmed using average ABPM or HBPM readings

Embedding these steps consistently is essential for safe hypertension diagnosis primary care pathways. Primary care teams must ensure confirmation is timely, results are reviewed by the right clinician, and patients are not left in prolonged monitoring states without action.

This stage benefits significantly from structured clinical pharmacist support, particularly in practices managing high volumes of ABPM and HBPM results.

Where case finding often breaks down

Despite national services and clear guidance, similar issues occur across systems:

• Raised readings are recorded but not followed up
• ABPM is requested but not completed
• Results return without clear ownership
• Patients fall between pharmacy, practice, and PCN workflows
• Treatment is initiated but not optimised

When hypertension case finding is not supported by a clear pathway, the risk shifts from under-detection to missed diagnosis and poor follow-up. This leads to avoidable cardiovascular risk and unnecessary workload across the system.

Why identifying undiagnosed hypertension matters

Undiagnosed hypertension carries significant consequences beyond individual patient risk. Persistently raised blood pressure is a major contributor to avoidable stroke, myocardial infarction, heart failure, and progressive kidney disease, all of which place long-term demand on acute, community, and social care services.

Earlier identification through structured hypertension case finding allows primary care to intervene before these complications occur. For the wider healthcare economy, this means fewer emergency admissions, reduced long-term prescribing burden, and improved population health outcomes. From a system perspective, the value of diagnosing hypertension early lies not only in improved patient outcomes, but in preventing downstream costs that are far more complex and expensive to manage.

From detection to blood pressure optimisation

The greatest clinical and system value of hypertension case finding in primary care comes after diagnosis.

This is where medicines optimisation hypertension activity becomes critical, ensuring treatment decisions are reviewed, adjusted, and aligned to NICE guidance rather than left static after diagnosis.

Effective pathways include structured medication reviews, stepwise titration aligned to NICE guidance, routine use of home monitoring, and clear recall and review processes. This is where medicines optimisation hypertension activity directly improves outcomes rather than simply increasing detection figures.

Clinical pharmacists and pharmacy technicians play a central role in medicines optimisation, adherence support, and safe titration. This is where medicines optimisation support helps practices translate detection into sustained blood pressure control while reducing GP workload.

Governance and delivery at PCN level

For PCNs and system leaders, hypertension pathway primary care delivery should be viewed as a population health intervention rather than a collection of services.

Successful delivery depends on clear ownership at each stage, defined handovers between pharmacy and practice, consistent coding, and workforce models designed for long-term value.

At PCN level, consistent medicines optimisation hypertension processes help reduce unwarranted variation between practices while improving long-term blood pressure control across populations.

When Additional Roles Reimbursement Scheme (ARRS) funding is deployed strategically, supported by models such as ARRS workforce support for PCNs, networks can scale hypertension case finding safely and effectively. Access to consistent clinical pharmacist support services enables PCNs to move from opportunistic detection to reliable diagnosis and optimisation at scale.

Clinical insight

Hypertension case finding only delivers value when primary care owns the full pathway. Identifying raised blood pressure is step one. Diagnosis, optimisation, and follow-up are where patient outcomes actually change.

Summary

Hypertension case finding in primary care represents a major opportunity to reduce avoidable cardiovascular disease across the NHS. Its success depends not on the number of checks completed, but on the strength of the pathway that follows.

When confirmation, diagnosis, and optimisation are owned by primary care, supported by community pharmacy and PCN-level workforce planning, hypertension case finding becomes a scalable, outcome-focused intervention that delivers long-term value for patients and the system.
