Every doctor, surgeon, dentist or other medical worker in this country, from a top consultant surgeon to a hospital porter, owes a duty to treat each patient to the best of their ability and in line with generally accepted best medical practice. In the medical world, perhaps more than in any other professional area, there can be significant differences of opinion about what should or should not be done to best treat a given condition or illness. The law recognises that since medical knowledge is always changing, different but nevertheless justifiable opinions can be held by medical professionals. It is not the law’s place to say whether one medical opinion is more valid than another. What the law does say, though, is that if a patient’s treatment was such that no reasonable medical professional (or body of professionals) could have justified it, then it will be negligent in law and if injury or damage is done as a consequence, the patient may have a claim for medical negligence compensation.
