How Hospital‑Acquired Infections Are Treated in Clinical Negligence

Hospital‑acquired infections - also known as healthcare‑associated infections (HCAIs) - occur when a patient contracts an infection while receiving care in a hospital or healthcare setting. These can include MRSA, Clostridium difficile, sepsis and urinary‑tract infections, among others. While not all such infections are the result of poor care, in some cases substandard hygiene, inadequate infection control and delays in diagnosis or treatment can cause avoidable harm. In England and Wales, where a patient suffers due to such lapses, they may be able to pursue a clinical negligence claim for compensation. This article explains how hospital‑acquired infections are treated in clinical negligence, the legal principles involved, how claims are investigated and practical guidance for patients and their advisers.

What Is a Hospital‑Acquired Infection?

Hospital‑acquired infections are infections that develop during or after a hospital stay which were neither present nor incubating on admission. They can arise from exposure to infectious organisms, contact with contaminated surfaces, equipment or carers, or complications following medical procedures. In England, it is estimated that around 300,000 patients per year develop healthcare‑associated infections, some of which may be linked to lapses in standards of care.

Common examples include:

• MRSA (Methicillin‑Resistant Staphylococcus Aureus)
• C. difficile (Clostridium difficile)
• E. coli infections
• Sepsis following surgery or catheter use
• Pressure sore infections and post‑operative wound infections

Legal Framework: Duty of Care and Negligence

Duty of Care

All healthcare professionals and institutions providing care owe patients a duty of care. This duty requires them to meet the standard of care expected of competent healthcare providers in similar circumstances. Where hospitals fail to maintain appropriate infection prevention and control (IPC) measures - such as hygiene protocols, sterilisation and early detection of infection - a breach of this duty may be established for legal purposes.

Breach of Duty and Standard of Care

To succeed in a clinical negligence claim involving a hospital‑acquired infection, a claimant must show:

1. A duty of care existed (for example, between the NHS trust or hospital and the patient).
2. The hospital breached that duty by failing to provide care meeting professional standards.
3. The breach caused avoidable harm, such as the contraction or worsening of an infection that would likely have been prevented with appropriate care.

This legal framework is grounded in longstanding principles of negligence applicable in England and Wales. Courts assess whether healthcare providers acted as a reasonably competent professional body would have done - a standard historically influenced by cases such as Bolam v Friern Hospital Management Committee and clarified in subsequent case law.

Distinguishing Infection from Negligence

Not all hospital‑acquired infections give rise to a claim. Many infections occur despite good care and strict hygiene controls. To establish negligence, it is necessary to show that infection control rules were breached, ignored or inadequately applied, and this directly contributed to harm suffered by the claimant.

How Negligence Is Proven in Infection Claims

Evidence Gathering

Successful claims depend on strong evidence, including:

• Medical records demonstrating when and how the infection was identified and treated.
• Infection control policies and protocols in place at the hospital.
• Independent expert reports from clinicians specialising in infection control or relevant medical fields.
• Photographic evidence and witness statements documenting hygiene issues or clinical responses.

Expert Medical Opinion

Experienced medical experts play a crucial role in clinical negligence claims. They review records, protocols and outcomes to determine whether the hospital's conduct fell below expected professional standards and whether a breach caused the infection or worsened the patient's condition. Expert evidence is often decisive in establishing both breach and causation.

Typical Scenarios Leading to Claims

Hospital‑acquired infection claims may involve scenarios such as:

• Poor hygiene practices, including inadequate handwashing or cleaning of wards and equipment, which increases infection risk.
• Failure to follow infection control protocols, such as improper sterilisation of surgical instruments or lax PPE use.
• Delayed diagnosis or treatment, allowing infections like sepsis to escalate because early signs were missed or ignored.
• Negligent post‑procedure care, where early indicators of infection were not responded to appropriately.

Because hospital infections can have serious consequences - extending hospital stays, necessitating further treatment or causing long‑term health problems - demonstrating that these outcomes were avoidable is central to negligence claims.

The Claims Process in England and Wales

Time Limits

Clinical negligence claims for hospital‑acquired infections must generally be brought within three years under the Limitation Act 1980. This period runs from either the date of the negligent act or the date when the claimant knew (or ought to have known) about the infection and its cause. There are exceptions for minors and those lacking mental capacity.

Pre‑Action Protocol

Before issuing court proceedings, claimants usually engage in a pre‑action protocol that involves sending a detailed letter of claim to the hospital or NHS trust with supporting evidence and medical records. The protocol encourages early disclosure and efficient resolution.

Negotiation and Court Proceedings

Many hospital infection claims settle through negotiation, without the need for a trial. If the hospital admits negligence, lawyers can agree compensation. Where liability is contested, proceedings may be issued in the High Court or County Court depending on the case's complexity and value.

Types of Compensation

Successful claims can include:

• General damages for pain, suffering and loss of amenity caused by the infection.
• Special damages for financial losses, including additional medical costs, loss of earnings and care expenses.
• Future care costs where the infection results in long‑term health impacts or disability.

Practical Guidance for Claimants

Consult Specialist Legal Advisers

Clinical negligence claims involving infections are often complex and require medical and legal expertise. Engaging specialist clinical negligence solicitors can help with evidence gathering, expert instruction and claim strategy.

Document Evidence Early

Keeping detailed records of symptoms, test results, communications with healthcare providers and any treatment received is important. Photographs of visible symptoms and written accounts of experiences can support a claim.

Understand That Not All Infections Lead to Claims

Establishing negligence requires proving that substandard care caused the infection. Mere contraction of a hospital‑acquired infection, without evidence of failings in care, does not automatically entitle a patient to compensation.

Common Questions

Can I claim if I developed an infection in hospital?
Yes, provided you can show negligence in care or infection control that led to the infection and resulting harm.

Do I need independent expert evidence?
Yes. Medical expert opinion is usually essential to prove that care fell below acceptable professional standards and caused avoidable harm.

What is the time limit for these claims?
Generally three years from when the infection was acquired or when you became aware that it was caused by hospital care. Exceptions may apply for minors or incapacitated claimants.

Final Thoughts

Hospital‑acquired infection claims in England and Wales are a specialised area of clinical negligence law. They require claimants to show that a healthcare provider's breach of duty - such as poor hygiene practices, failures in infection control or delays in diagnosing or treating infection - caused avoidable harm. Establishing liability depends on careful evidence gathering and expert assessment of clinical standards. Patients and their representatives should seek specialist advice early, maintain comprehensive documentation, and understand both the legal criteria and procedural requirements involved in pursuing compensation for hospital‑acquired infections.
