Reducing Costs in Cardiology Litigation: Strategic Use of Screening Reports

The Medico-Legal Value of Early Cardiology Screening

In complex cardiac clinical negligence litigation, identifying the merits of a claim at the earliest possible stage is a critical factor in managing legal costs and satisfying the requirement for proportionality under the Civil Procedure Rules (CPR). The strategic use of a cardiology screening report allows instructing parties to evaluate whether the alleged index events constitute a viable breach of duty, or if the clinical care fell within the range of responsible professional practice.

In cardiology medico-legal practice, an early assessment focuses on whether the clinical care provided aligns with established practice at the time of the alleged event. A screening report typically reviews the chronology and key medical records to determine if a primary report is likely to yield evidence of a breach that caused actionable harm. Solicitors may seek expert assistance for initial merits assessments to determine whether to proceed with a formal report under CPR Part 35, which is inherently more resource-intensive.

Clinical Frameworks and the Bolam/Bolitho Test

Cardiology claims often hinge on the interpretation of clinical decisions regarding complex pathways, such as the use of diagnostic assays or the application of risk stratification tools. A screening report provides a preliminary view on whether these decisions were defensible under the Bolam v Friern [1957] test, which requires the defendant to show they acted in accordance with a practice accepted as proper by a responsible body of medical opinion.

However, under Bolitho v City and Hackney HA [1998], the court may reject expert opinion if it is not grounded in a logical clinical basis. A cardiology expert reviewing a case during the screening phase will examine whether the clinical decision-making was consistent with evidence-based pathways, while noting that clinical judgement often involves balancing risks in the context of the patient’s comorbidities, such as heart failure, valve disease, or established ischaemic heart disease.

Strategic Deployment of Expert Resources

The decision to commission a formal report is distinct from the commissioning of a screening report. Under CPR 35.1, expert evidence must be restricted to that which is reasonably required to resolve the proceedings. A screening report serves as an essential threshold assessment tool:

• Merits Evaluation: It identifies whether the clinical documentation contains a plausible assertion of deviation from standard care.
• Causation Assessment: It assists in considering whether the alleged injury is capable of being causally linked to the index event, applying the ‘but-for’ test of causation rather than speculating on remote outcomes.
• Cost Efficiency: By clarifying the medical focus early, parties avoid unnecessary costs associated with comprehensive reports on issues that may be clinically unsustainable.
• Proportionality: It facilitates the triage of cases, ensuring that litigation focus remains on claims with a substantial prospect of success.

It is vital to note that a screening report is not a formal CPR Part 35 compliant report. It does not carry the same procedural weight in court and is generally considered a tactical tool for the instructing party.

Common Pitfalls and the Role of the Expert

A frequent pitfall in cardiac litigation is the retrospective analysis of decisions based on outcomes rather than the information available to the clinician at the time. An expert reviewing a case for screening must maintain independence and focus on the clinical context existing at the time of the treatment. An adverse clinical outcome, in isolation, is not proof of a breach of duty. The focus should instead remain on whether the triage and diagnostic processes performed at that specific moment met the required standard of care.

Expert opinion may address whether the failure to escalate, the delay in investigation, or the procedural complications encountered in interventions fell outside the range of reasonable clinical performance. The screening expert plays a vital role in flagging these areas to the solicitor, potentially highlighting whether the case requires further input from a specialist in sub-disciplines such as electrophysiology, structural heart disease, or cardiac surgery.

Practical Guidance for Instructing Solicitors

To maximise the utility of a cardiology screening report, instructing solicitors should ensure that the brief includes a clear, chronological summary of the clinical records, the specific questions to be addressed, and all relevant investigation results, such as ECGs, echocardiography reports, and coronary angiography findings. An expert needs to see the objective evidence rather than just the summary of alleged failures.

Where the court directs the appointment of a Single Joint Expert (SJE), the instruction process is governed by CPR 35.8. An SJE does not participate in a joint statement process under CPR 35.12, as their duty is to the court as a single neutral source of expertise. Specialist cardiology medico-legal assessment remains pivotal in determining the trajectory of a claim, provided that legal arguments remain tethered to the documented medical evidence.
