Sepsis Pathway Failures: Why A&E, ICU and GP Experts Are All Required in Delayed Sepsis Claims

Sepsis remains a significant challenge in clinical practice and a key area for litigation within the UK. Claims arising from alleged failures in sepsis recognition and management often involve complex sequences across multiple healthcare settings. For solicitors handling clinical negligence, personal injury, CICA claims or inquests, understanding the multi-disciplinary nature of sepsis care and the required expert evidence is critical. Establishing breach of duty and causation in these cases requires detailed analysis by subspecialist experts who can assess the standard of care at each stage of a patient’s journey.

Clinical Context: Understanding Sepsis and Its Pathways

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. It can rapidly progress to septic shock, characterised by circulatory, cellular and metabolic abnormalities, with significantly increased mortality risk. Early recognition and timely intervention are paramount, as outlined in national initiatives such as the ‘Sepsis 6’ care bundle and the National Early Warning Score (NEWS2).

The patient journey through sepsis may involve several healthcare contacts:

• General Practice (GP): Initial presentation often occurs in primary care, where symptoms may be non-specific. A GP expert witness assesses red flag recognition, safety netting advice, timely investigation and referral standards.
• Emergency Department (A&E): Patients are triaged and assessed in A&E. Rapid assessment, accurate NEWS2 scoring, immediate investigations (including lactate and blood cultures), appropriate fluid resuscitation and prompt antibiotic administration are crucial. An A&E expert scrutinises these time-critical pathways.
• Intensive Care Unit (ICU): If sepsis progresses to septic shock or multi-organ failure, ICU transfer may be required for advanced organ support. An ICU expert witness assesses critical care admission appropriateness, ongoing management standards, antimicrobial stewardship and long-term prognosis.

NICE guideline NG51 provides a framework for sepsis recognition, assessment and early management across these settings. Alleged deviations from these or accepted clinical standards form the basis for breach of duty arguments.

Legal Relevance: Breach, Causation and Complexities

Clinical negligence claims involving sepsis typically require establishing both breach of duty and causation. The Bolam and Bolitho tests remain central to determining whether the care provided met acceptable standards. Expert opinion must demonstrate that no responsible body of medical practitioners would have acted similarly and that the alleged breach lacked logical justification.

Causation can be particularly challenging due to sepsis’s rapid progression and potential co-morbidities. The ‘but for’ test requires proof that the adverse outcome would not have occurred but for the alleged breach. Where multiple factors contribute, principles of material contribution or loss of chance may apply. Expert evidence on the counterfactual scenario – what would have happened with appropriate care – is therefore crucial.

Inquest proceedings involving sepsis deaths also benefit from detailed expert evidence. Experts may assist coroners in determining medical cause of death and identifying systemic issues that could lead to Prevention of Future Deaths reports.

The Multi-disciplinary Expert Approach

An effective sepsis claim strategy requires carefully matched expertise. Given the pathway’s complexity, a single expert may not possess the detailed knowledge to comment authoritatively across all care phases.

• General Practitioner Expert: Provides opinion on initial presentation, diagnostic challenges, referral thresholds and follow-up duties.
• Accident and Emergency Expert: Focuses on A&E assessment and management, including triage accuracy, vital signs interpretation, investigation ordering and escalation decisions.
• Intensive Care Unit Expert: Comments on severe sepsis management, critical care interventions, organ support efficacy and long-term damage implications.

In complex cases where alleged breaches span multiple settings, instructing a panel of experts ensures each pathway aspect is scrutinised against the appropriate standard of care, providing a robust evidential foundation.

Common Pitfalls and Evidential Disputes

Common issues include instructing generalists when subspecialist input is required. Disputes often arise regarding:

• Timing of sepsis onset and progression
• Interpretation of clinical signs
• Adequacy of medical records documentation
• Impact of co-morbidities on prognosis
• Applicability of specific guidelines to the clinical context

Expert witnesses must address these complexities through forensic record review and detailed understanding of sepsis natural history versus alleged sub-standard care impact.

Practical Guidance for Instructing Solicitors

For solicitors handling sepsis claims:

1. Map the patient journey: Identify all healthcare contact points from initial symptoms to final outcome.
2. Identify alleged breach points: Determine where evidence suggests deviation from accepted standards.
3. Match expertise to breaches: Instruct GP experts for primary care failings, A&E experts for emergency department issues and ICU experts for critical care concerns.
4. Provide comprehensive records: Supply all relevant medical notes, observation charts, laboratory results and witness statements.
5. Consider joint instructions: Where appropriate, use single joint experts or joint discussions to clarify overlapping issues.

The role of sepsis claim experts extends beyond identifying failings to articulating the causal link between breaches and adverse outcomes while accounting for the condition’s inherent severity. Multi-disciplinary medico-legal chambers can provide the precise subspecialist expertise required for these complex cases.
