Case Study | Confusion, Documentation and Defence: a Nursing Expert’s View on Inpatient Falls

Falls involving elderly patients remain one of the most common and complex sources of clinical negligence claims against hospitals. When a fall occurs, particularly where the outcome is serious or fatal, scrutiny quickly follows. Were the risks properly assessed? Were safeguards appropriate? And did the care provided meet the standard of a responsible body of clinicians working in real conditions?

This anonymised case, reviewed by an experienced clinical negligence nursing expert witness, illustrates how falls risk, delirium, and documentation intersect in both clinical practice and legal analysis. It also highlights a recurring challenge in litigation: where care is imperfect, but causation and breach are far from straightforward.

Background to the Case

The patient was an elderly man admitted to hospital with sepsis, acute delirium, and significantly reduced mobility. His presentation included confusion, hallucinations, and fluctuating levels of consciousness. These features placed him squarely within a high-risk cohort for inpatient falls.

During his admission, he sustained a fall on the ward. He later deteriorated and sadly passed away. A claim was subsequently pursued, alleging failures in falls risk assessment, delirium management, and nursing care.

A senior clinical negligence expert was instructed to review the nursing records, risk assessments, and wider clinical context to determine whether the care provided fell below an acceptable standard and, if so, whether that breach was causative.

Falls Risk is Dynamic, Not a One-off Assessment

One of the central themes identified by the expert was the dynamic nature of falls risk, particularly in patients with delirium.

A formal falls risk assessment was completed on admission, which in itself was appropriate. However, subsequent documentation painted an inconsistent picture of the patient’s cognitive state. While earlier entries referred to acute confusion and hallucinations, later records - including bed rail assessments - described the patient as “drowsy” rather than confused. This inconsistency mattered.

Falls risk is not static, especially in cases of delirium, where cognition can fluctuate hour by hour. Best practice requires ongoing reassessment, with care plans adjusted to reflect changes in mental state, mobility, and physiological stability.

As the expert observed:

“Falls risk evolves daily - sometimes hourly - in patients with delirium. Without a coherent care plan, it becomes difficult to demonstrate that risks were actively managed rather than passively recorded.”

Documentation gaps and their legal significance

The expert identified notable gaps in the nursing documentation. While risk assessments existed in isolation, there was no clear, delirium-specific care plan setting out how risks would be mitigated in practice.

In particular, the records lacked evidence of:

• A structured delirium management plan

• Reassessment of mobility as cognition changed

• Lying and standing blood pressure measurements

• Clear escalation triggers or enhanced observation strategies

From a legal perspective, documentation serves two functions. Clinically, it guides care. Legally, it provides the evidence that care was considered, proportionate, and responsive. Where documentation is fragmented or contradictory, defending care becomes significantly more difficult.

However, poor documentation alone does not establish negligence. The key question remains whether the care itself fell below a reasonable standard.

NICE Guidance and Expected Standards

The expert benchmarked the care against relevant national guidance, including:

• NICE CG103 - Delirium: diagnosis, prevention and management

• NICE NG249 - Falls in older people: assessing risk and prevention

Both emphasise the need for regular reassessment, multidisciplinary input, and tailored interventions where cognition and mobility are impaired. In this case, the absence of a documented delirium care plan and limited evidence of ongoing reassessment represented departures from ideal practice.

The expert concluded that these omissions amounted to substandard care, particularly given the known risks associated with delirium and sepsis.

Breach Versus Causation: a Critical Distinction

Despite identifying shortcomings, the expert was careful to separate breach of duty from causation.

Importantly, the patient’s cognition was documented as improving in the period leading up to the fall. This improvement complicated the causation analysis. While earlier failures in delirium planning were concerning, it was not possible to say with confidence that different documentation or assessments would have prevented the fall at that specific point in time.

Under the legal tests established in Bolam v Friern Hospital Management Committee [1957] and Bolitho v City and Hackney Health Authority [1998], a claimant must show not only that care fell below an acceptable standard, but that the breach caused the harm complained of.

In this case, that causal link was difficult to establish.

Staffing pressures and real-world context

Another critical factor was the ward environment on the night of the fall. The ward was short of two registered nurses, and another patient in the same bay required continuous attention.

The expert did not dismiss these pressures. On the contrary, they were considered an essential part of the analysis. Clinical negligence experts are not tasked with judging care in a vacuum. They must assess whether, even in challenging circumstances, the care provided remained within the bounds of acceptable practice.

However, the expert noted that where staffing pressures affect care delivery, this should be reflected in the records. Documentation of prioritisation, observation decisions, and risk management becomes even more important when resources are stretched.

The Role of the Clinical Negligence Nursing Expert

This case illustrates the nuanced role of the clinical negligence expert. Their task is not simply to identify errors, but to weigh:

• Clinical standards and guidance

• The realities of ward-based nursing

• Documentation quality

• Patient-specific risk factors

• Staffing levels and competing demands

Only by considering these factors together can an expert offer a balanced opinion on breach and causation.

In this instance, the expert identified aspects of care that fell below expected standards, particularly around delirium planning and reassessment. However, the evidence did not support a clear causal link between those failings and the fall itself.

Lessons for Practice and Litigation

For healthcare providers, this case reinforces the importance of coherent, consistent documentation - especially where patients are confused, unstable, or at high risk of falls. Risk assessments must translate into practical care plans that evolve with the patient.

For legal practitioners, it demonstrates that not every substandard aspect of care will give rise to a successful claim. Causation remains a significant hurdle, particularly in complex medical cases involving frail patients with multiple risk factors.

And for those instructing experts, it highlights the value of clinicians who understand both frontline nursing realities and the legal tests applied by the courts.
