A nurse-led heart murmur clinic at Sheffield Children’s Hospital offers a useful example of how Operational Research thinking can support better outpatient pathway design. By changing who does what, when, and through which channel, the service has reduced waiting times, made better use of specialist capacity and improved the efficiency of care for children referred with heart murmurs.

Introduced in 2023, the clinic was designed to relieve pressure on consultant-led services while giving clinical nurse specialists a more central role in the patient pathway. According to a review published by the British Journal of Cardiology, the model reduced the average wait from referral to completion of assessment from around 16 weeks to about five to six weeks. It also generated estimated first-year savings of more than £3,000 for the NHS trust.

For an Operational Research audience, the interest lies less in the clinical condition itself and more in the design of the pathway. Many childhood heart murmurs are ultimately found to be innocent, but families still need assessment, explanation and formal discharge where no structural problem is found. The challenge is to provide that care safely and efficiently, without placing unnecessary pressure on consultant capacity.

The Sheffield pathway begins with triage by paediatricians with a special interest in cardiology. They decide whether a child can safely be managed through the nurse-led service or whether they need consultant input. Where appropriate, echocardiography is arranged in advance, and families are then booked into a fortnightly telephone clinic run by a clinical nurse specialist.

This process is important because it separates patients by need and directs them to the most appropriate part of the system. Children whose scans show no structural heart problem can receive reassurance and be discharged by the nurse-led clinic. If an abnormality is detected, the case is escalated to a paediatric cardiologist. In OR terms, this is a practical example of triage, risk stratification and capacity management working together.

The telephone clinic also closes a gap in the pathway. Even when a scan is normal, sonographers cannot usually provide results, write discharge letters or formally close the episode of care. Without a follow-up process, families may still need a further appointment simply to receive reassurance and confirmation. By using a nurse-led telephone clinic, the service provides that explanation while avoiding unnecessary consultant appointments.

The model also highlights the importance of skill mix. Consultant time is a scarce and valuable resource, particularly in specialist services. By allowing clinical nurse specialists to manage appropriate cases, the pathway releases consultant capacity for children who need more complex assessment. At the same time, it extends the role of specialist nurses, giving them greater responsibility for interpretation, communication and discharge.

Financially, the savings reported in the first year were modest, but the operational lesson is larger. Small changes in pathway design can improve throughput, reduce delays and make better use of existing staff. The review estimates that a consultant can see two new patients an hour at a staffing cost of £75.50 an hour, compared with three new patients an hour for a clinical nurse specialist at £25.16 an hour. Across 108 patients in the first year, this produced estimated savings of £3,182.04.

For Operational Research professionals, the clinic is a clear example of how service redesign can improve access without compromising care. It brings together several familiar OR themes: patient flow, triage, resource allocation, workforce planning, process improvement and decision support.

At a time when outpatient services face sustained pressure, examples like this matter. They show how relatively small operational changes can make pathways faster, more efficient and more responsive to patient need. Better design does not always mean adding more resources. Sometimes it means using the resources already in the system more intelligently.
