Beatty v Lewisham and Greenwich NHS Trust

Factual and Procedural Background

In April 2016, the Plaintiff was an in-patient at the hospital operated by the Defendant. The Plaintiff alleged that a vascular surgeon employed by the Defendant failed to diagnose an embolism during a consultation on 13th April 2016. This failure allegedly led to the necessity of a below-knee amputation of the Plaintiff's right leg in May 2016 at a different hospital. The clinical negligence claim focuses solely on the vascular surgeon's assessment on 13th April, with no negligence alleged before or after that date. The trial was brief, lasting one day with limited documents and evidence, including oral testimony from the vascular surgeon and two expert witnesses.

The Plaintiff was admitted following a fall and treated for a severe bacterial skin infection and cellulitis. Various medical assessments and imaging were performed between 5th and 13th April, including Doppler and Duplex ultrasounds, echocardiogram, and clinical reviews by multiple physicians and vascular specialists. The vascular surgeon's assessment on 13th April concluded a diagnosis of vasculitis rather than embolism, leading to no further vascular input. The Plaintiff self-discharged on 23rd April but returned unwell on 26th April, by which time experts agreed it was too late to save the leg. It was also agreed that the Plaintiff suffered from an embolic disease process originating in the distal aorta, not vasculitis.

Legal Issues Presented

1. Whether it was mandatory for the vascular surgeon to order a CT angiogram of the Plaintiff's aorta on 13th April 2016 to exclude embolism.
2. Whether the vascular surgeon's diagnosis of vasculitis rather than embolism was supported by a reasonable body of medical opinion.
3. Whether the vascular surgeon's clinical judgment was logically supported and reasonable in the circumstances.

Arguments of the Parties

Appellant's Arguments

• The vascular surgeon was not entitled to definitively rule out embolism and diagnose vasculitis without further investigation.
• Given the presenting features and concerns of other hospital doctors, a CT angiogram was mandatory to exclude embolism.
• The diagnosis of vasculitis was not acceptable to a reasonable body of vascular surgeons in April 2016.
• The failure to order a CT angiogram resulted in a missed diagnosis and delayed treatment, leading to amputation.

Appellee's Arguments

• The vascular surgeon’s clinical judgment was reasonable given the negative findings on Doppler and Duplex scans, absence of atrial fibrillation, and normal echocardiogram.
• The diagnosis of vasculitis was supported by a reasonable body of medical opinion and was a diagnosis of exclusion.
• CT angiography was not indicated or mandatory at the time of assessment on 13th April 2016.
• Resource considerations and clinical judgment allow for not undertaking all conceivable tests when the likelihood of embolism was very low.

Court's Reasoning and Analysis

The court began by identifying the key issue: whether the vascular surgeon was obligated to order a CT angiogram on 13th April 2016. The court acknowledged that the vascular surgeon’s diagnosis of vasculitis was a diagnosis of exclusion, based on clinical findings including normal arterial flow on imaging, absence of atrial fibrillation, and an echocardiogram showing no cardiac source of embolism.

The court critically assessed the expert evidence. The Plaintiff’s expert was found to be partisan, lacking detailed reasoning and failing to adequately engage with the vascular surgeon’s witness statement. The Plaintiff’s expert’s assertion that CT angiography was mandatory was considered insufficiently supported and imprecise, confusing “optimal” with “mandatory.”

The Defendant’s expert provided a measured and logical explanation supporting the vascular surgeon’s clinical judgment as reasonable and consistent with a responsible body of medical opinion. The court accepted that the vascular surgeon’s clinical judgment involved assessing the likelihood of embolism as very low, and that it was not necessary to exclude every conceivable diagnosis by exhaustive testing.

The court emphasized that clinical judgment often involves uncertainty and that the vascular surgeon was not required to definitively exclude embolism but to make a reasoned clinical assessment. The court accepted the reformulated legal test that if embolism was a realistic possibility, further investigation would be mandatory, but found that the evidence supported the conclusion that embolism was not a realistic possibility at the time.

Accordingly, the court found that the vascular surgeon’s decision not to order CT angiography was supported by a reasonable body of medical opinion and was logically justified.

Holding and Implications

The court's final decision was to DISMISS the clinical negligence claim against the Defendant.

The direct effect of this decision is that the Defendant is not liable for the alleged failure to diagnose embolism or for any resulting harm from that failure. No new legal precedent was established, as the decision was grounded in the application of established principles concerning medical negligence and clinical judgment under the Bolam test and its logical refinement.
