Dr. David Thomas

< Back

Having spent 14 years in clinical medicine, including 3 years as a consultant cardiologist, I bring expert medical insight to my primary area of clinical negligence, and am frequently instructed by national firms in this area.

I have a clear understanding of the issues of anatomy, physiology and pathology that can result from an alleged negligently performed procedure or negligent treatment. With an emphasis on claimant work, I undertake work in a wide range of medical specialties including surgery, obstetrics, gynaecology and orthopaedics, and sub-specialties such as cardiology and cardiac surgery. I have a developed a particular interest in cases involving corrective laser eye surgery, and undertake cases in relation to issues of consent.

I regularly appear at Inquests on behalf of relatives of those who have died, where there may be a potential claim in clinical negligence.

I am happy to be involved from an early stage in the process of litigation of a proposed claim, and I frequently advise on the instruction of appropriate experts. I am willing to receive instructions electronically as well as on paper.

Notable Cases

Finnie v South Devon Healthcare NHS Foundation Trust [2014] EWHC 4333 (QB)

The claimant had undergone an operation for which there was no clinical indication or need. Following surgery for mega-rectum the bowel anastomosis broke down resulting in significant pelvic sepsis with damage to the female reproductive organs. The claimant required 27 further abdominal operations to attempt to correct the complications of the negligent surgery. The defendant denied breach of duty until two weeks before trial, and only then making limited admissions. At trial the defendant then made further admissions and admitted causation.

The claimant was ultimately awarded £705,000 (including pension loss).

B v P, C & Yeovil Hospitals NHS Trust

Claimant suffered loss of vision in both eyes as a result of a failure to recognise the development of ischaemic and embolic damage to the visual system, in a young woman on the combined oral contraceptive pill with an underlying clotting disorder and congenital heart defect. The matter is due to go to trial in early 2017.

S v Barts Health NHS Trust

The claimant was an elderly man with depression who sustained an injury to the neck. When he attended the Accident and Emergency Department he was not examined and as a result no x-ray of the neck was undertaken which would have demonstrated a fracture of the odontoid peg of the 2nd cervical vertebral body. He was discharged home and over the following day developed significant neurological deficit.

S v Calderdale & Huddersfield Hospitals NHS Trust

Claimant was a man in his late 30s who presented to the Accident and Emergency Department with central chest pain which the defendant ultimately accepted was cardiac in nature. At the time he was informed that he had dyspepsia and was discharged home. He was admitted 2 days later to the same hospital with cardiogenic shock and was shown to have suffered a myocardial infarction. He was left with very poor left ventricular function and very impaired exercise capacity, and the expert evidence concluded that he would only achieve symptomatic improvement with a cardiac transplant.
