Identifying Diagnostic Delay in Paediatric Sepsis Claims

Identifying diagnostic delay in paediatric sepsis requires a forensic approach to clinical record-keeping, as the subtle onset of symptoms in children often presents diagnostic challenges. Determining whether a delay in recognition or treatment constitutes a breach of duty depends on whether the clinical presentation at a specific juncture provided sufficient information for a competent practitioner to suspect sepsis and initiate timely management. Legal professionals reviewing these cases should distinguish between the subjective difficulty of diagnosing sepsis in its early stages and failures to document, observe, or escalate care in accordance with standards applicable at the time.

Reviewing Clinical Records and Chronology

The first step in evaluating a claim involves establishing a robust chronology of the child’s clinical state. This necessitates a comprehensive review of primary care records, ambulance call-out forms, emergency department notes, and inpatient charts. Instructors should seek to identify the precise time at which clinical indicators of concern first manifested. The absence of documentation regarding vital signs—specifically temperature, heart rate, respiratory rate, and oxygen saturation—is often as significant as the documented findings themselves. When evaluating clinical evidence relating to early childhood development, the records must demonstrate whether clinicians accounted for the child’s baseline state versus their acute deterioration.

Key Records for Audit

• Triage notes and initial clinical assessments: These provide the baseline for assessing whether clinicians were presented with a history that warranted higher clinical suspicion.
• Observation charts: Look for gaps in monitoring, particularly during periods where the child’s condition was reported as ‘unsettled’ or ‘not acting right’.
• Fluid balance and urine output records: Oliguria is a critical indicator of perfusion, yet it is frequently missed in retrospective audits.
• Escalation pathways: Determine if there was a failure to involve senior decision-makers (e.g., a registrar or consultant) when the child failed to improve after initial interventions.

Discipline Selection and Expert Instruction

The complexity of paediatric sepsis often requires expert input across multiple disciplines. A consultant paediatrician is typically required to assess the general standard of care, whereas cases involving suspected neurological involvement, such as injury from profound hypotension, may necessitate a concurrent report from a consultant paediatric neurologist.

Under the Civil Procedure Rules (CPR) Part 35 in England and Wales, an expert’s duty is to provide an objective, independent opinion to the court. If solicitors are considering a single joint expert pursuant to CPR 35.7, they must ensure the expert is instructed in accordance with CPR 35.8 and provided with a complete, agreed-upon bundle of evidence to avoid disputes over the chronology. Where parties instruct separate experts, CPR 35.12 allows for discussions to narrow the issues, but this process remains distinct from the experts’ individual evidence. Experts should be encouraged to specify where clinical findings are equivocal, as diagnostic pathways in the early stages of infection are rarely linear.

Common Reasoning Errors in Sepsis Litigation

A common error in assessing diagnostic delay is the application of hindsight. A finding of sepsis in retrospect does not automatically imply that the diagnosis was readily available to the treating clinician at the time. Experts must apply the standard of the reasonable body of medical opinion at the time of the alleged incident. Furthermore, legal teams should be cautious of over-relying on a single abnormal vital sign as a definitive marker. Clinical judgement involves integrating the child’s overall appearance, parental concerns, and the trend of observations over time.

Distinguishing Causation from Breach

Establishing that a delay occurred is not sufficient to succeed in a clinical negligence claim; one must also demonstrate that the delay caused the injury. In cases of paediatric sepsis, this requires an expert to postulate the ‘but-for’ scenario: what would have been the outcome had the diagnosis been made, for instance, two hours earlier? This often hinges on whether effective antibiotic administration or fluid resuscitation within that window would have altered the pathophysiological trajectory. Experts must qualify their opinions, as the efficacy of intervention is influenced by the severity of the infection and the child’s pre-existing health status.

Practical Considerations for Instructions

When instructing a paediatric expert, consider the following points to ensure the report provides maximum utility:

• Provide a concise summary of the factual dispute: If the parents and the clinicians differ on the child’s state at a particular time, instruct the expert to provide opinions based on both potential factual outcomes.
• Ask the expert to identify the specific moment of reasonable suspicion: Rather than asking for a definitive ‘delay’, ask at what point a competent clinician should have suspected sepsis and what actions were warranted at that point.
• Limit the scope to clinical issues: Ensure the expert does not stray into matters of law or legal interpretation, which are the purview of the court.
• Identify gaps in evidence: If the clinical records are incomplete, ask the expert to state what information is missing and whether that information would have been critical to the diagnostic process.
