In order to win a medical malpractice case, there is a lot more to prove than a failure to diagnose or treat by a physician, surgeon, nurse, hospital or clinic. A medical malpractice lawsuit is won by proving numerous conditions and failures existed and/or occurred, during the course of treatments.

First a St. Louis medical malpractice lawyer must prove that a doctor/ patient relationship, actually existed in the first place. Then, there needs to be a provision of care proven, that falls or fell below the accepted medical standards of care. Often these provisions of care include; decisions made on how to treat and when to treat, decisions on the types of treatments and/or a failure to treat, and/or a misdiagnosis. It must be proven that these provisions of care fell below the accepted medical standards of care, and that there was a breach in that standard of care, that resulted in medical negligence, according to Missouri Law. Next to be proven in a medical malpractice case is that a “causal connection” existed between the hospital, clinic or physicians medical negligence and the patient’s injuries suffered or the harm they suffered, as a result. These injuries or the patient’s harm also has to be quantifiable harm, as in damages that occurred to the patient as a result of the negligence.

Many times the causal connection and the quantifiable damages are the most difficult to prove due to many other illnesses, injuries, treatments or side effects the patient is experiencing.

At Sumner Law Group, we hire the best medical experts in the U.S. to provide key evidence and testimony to the jury. It is crucial the jury understands the illness or injuries of the patient/plaintiff, what the appropriate diagnosis and treatments should have been and what the hospital, doctor or surgeon did or did not do, that fell short of the acceptable medical standards of care, thereby, breaching their duties of care and/or how they contributed to medical negligence.

In Missouri, medical malpractice lawyers will need to submit an affidavit of merit stating that the expert agrees the defendant's negligence caused your patient’s injuries. This affidavit needs to be filed within 90 days of filing the complaint. If more than one medical professional is believed to have caused the harm, an affidavit of merit must be filed with respect to each of them.
