  • Medicines Safety Enhancement – Providing specialist oversight for complex medication queries, high-risk drug monitoring, medicines reconciliation, and comprehensive medication reviews to reduce prescribing risks.
  • Practice Sustainability Model – Creating a scalable, sustainable approach to managing workload pressures in general practice while protecting GP capacity for complex clinical cases.

Problem

Colney Hatch Lane Surgery, serving approximately 6,456 patients, was facing the intense workload pressures that have become characteristic of modern general practice. Like many primary care practices across the NHS, the surgery was struggling to balance increasing patient demand against
limited clinical capacity.

The practice’s General Practitioners were experiencing unsustainable workload levels, managing not only complex clinical consultations but also high volumes of routine medication requests, minor ailment presentations, chronic disease management, and administrative tasks. This pressure was creating multiple interconnected problems:

  • Extended Patient Wait Times: Patients were waiting an average of 3 weeks for routine GP or clinician appointments, leading to frustration, delayed care, and potential deterioration of manageable conditions.
  • GP Burnout Risk: Existing GPs were working at maximum capacity with no scope to absorb additional demand, creating sustainability concerns for the practice’s clinical workforce.
  • Inefficient Resource Utilisation: Highly trained GPs were spending significant time on tasks that could be appropriately managed by other clinical professionals, such as medication reauthorisations and minor ailment assessments.
  • Medicines Management Gaps: Limited capacity for proactive medicines optimisation, high-risk drug monitoring, and comprehensive medication reviews meant potential safety issues and suboptimal prescribing were not being systematically addressed.
  • Chronic Disease Management Pressures: Patients with long-term conditions such as asthma, hypertension, depression, and atrial fibrillation required regular reviews, but GP capacity constraints made it difficult to deliver these systematically.

The practice recognised that simply asking existing staff to work harder was not sustainable or safe. They needed a strategic solution that would add genuine clinical capacity, deliver appropriate care at the right level, and create a more efficient and sustainable model of primary care delivery.

Challenge

The fundamental challenge was to reduce GP workload pressures and improve patient access without compromising clinical quality or creating unsustainable financial burdens. The practice needed a solution that would:

Key Challenges:

  • Deliver Immediate Capacity: Provide substantial clinical capacity quickly to address the backlog of routine
    appointments and ongoing demand.
  • Be Cost-Effective: Operate within the practice’s financial constraints, delivering value that justified the investment.
  • Maintain Clinical Standards: Ensure all care delivered met professional standards and integrated seamlessly with existing practice protocols
  • Cover Diverse Clinical Areas: Address the full range of workload pressures including triage, minor ailments, medicines management, chronic disease reviews, and high-risk drug monitoring.
  • Integrate into Existing Workflows: Work collaboratively with the existing team without disrupting established processes or creating additional coordination burden.
  • Prove Sustainable: Demonstrate that the model could be maintained long-term as a permanent solution rather than a temporary fix.

Critically, the practice needed to demonstrate measurable improvements in both operational metrics (wait times, appointment availability) and clinical outcomes (medication safety, chronic disease control) to justify the investment and prove the model’s effectiveness.

Solution: Integrated Pharmacist Support

The Medicines Management Team partnered with Colney Hatch Lane Surgery to provide a dedicated, full-time(1.0 FTE) Advanced Clinical Pharmacist integrated directly into the practice’s daily clinical operations. This was not a peripheral or project-based service, but a fundamental addition to the practice’s clinical team.

Service Delivery Model:

The Advanced Clinical Pharmacist became a core member of the clinical team, working on-site full-time with direct access to clinical systems, integrated into practice meetings, and functioning as a first-line clinician for appropriate patient presentations.

The pharmacist delivered comprehensive clinical services across multiple domains:

  • Clinical Triage: Managing incoming patient requests through Accurx and telephone consultations, assessing clinical urgency, and directing patients to appropriate care pathways or managing conditions directly.
  • Minor Ailment Clinics: Independently assessing, diagnosing, and treating patients presenting with minor health conditions, providing same-day resolution for appropriate cases.
  • Medicines Management: Overseeing prescription reauthorisations, managing complex medication queries, providing specialist advice on drug interactions, contraindications, and optimal prescribing.
  • Long-Term Condition Reviews: Conducting specialised clinics for patients with chronic diseases including Asthma, Depression, Hypertension, and Atrial Fibrillation, ensuring evidence-based management and regular monitoring.
  • High-Risk Drug Monitoring: Proactively identifying and monitoring patients on high-risk medications (such as anticoagulants, immunosuppressants, and other drugs requiring regular surveillance), ensuring appropriate blood tests and safety protocols.
  • Medicines Reconciliation & Medication Reviews: Performing comprehensive reviews to optimise patient prescriptions, identify polypharmacy issues, reduce inappropriate prescribing, and ensure medication accuracy following hospital discharge or care transitions.

This comprehensive service model meant that the pharmacist could manage a substantial proportion of the clinical workload that would traditionally require GP time, while simultaneously improving the quality and safety of medicines management across the entire practice population.

The Medicines Management Team’s pharmacist completed reviews across all required categories: – SMR01A, SMR01B, SMR01C, SMR01D SMR02A, SMR02B, SMR02C, SMR02D – SMR03.
