When a medical procedure goes wrong or a diagnosis is missed, the experience can leave you feeling confused, injured, and uncertain about your future.
Seeking a resolution after experiencing medical malpractice can feel overwhelming, especially while you are recovering. We would like to welcome you and provide a clear, helpful understanding of the evidence required. Proving a medical malpractice case in Washington is complex. It requires showing more than just an undesirable outcome; it demands proof of negligence that directly led to your injury.
The Four Essential Elements of a Washington Malpractice Claim
In Washington State, a medical malpractice claim must establish four main legal elements to be successful. These elements form the foundation of your case, and you must prove all four by a preponderance of the evidence, meaning it must be more likely than not that each element is true.
1. Duty of Care
The first step is establishing that a formal doctor-patient relationship existed. When you become a patient, the healthcare provider, whether a doctor, nurse, or hospital, accepts a legal duty of care toward you, which simply means they are professionally obligated to treat you according to an accepted standard. This element is usually the easiest to prove, often requiring just your medical records to show you were a patient receiving care.
2. Breach of the Standard of Care
Breach of the standard of care is the most critical and often the most challenging element to prove. The standard of care refers to the level of skill, care, and learning that a reasonably prudent healthcare provider in the same profession, and in the state of Washington, would have exercised in the same or similar circumstances.
To prove a breach, you must show the provider’s actions or inactions fell below this accepted standard. Washington law sets out this required element of proof. This element is not about a bad result, but a bad process, a mistake that another competent provider would not have made.
3. Causation: The Link Between Breach and Injury
You must prove that the healthcare provider’s breach of the standard of care was the direct and proximate cause of your injury. It’s not enough to show that a mistake occurred and you were injured. You must prove that the mistake caused the injury.
4. Damages
Finally, you must prove that you suffered actual damages as a result of the injury caused by the breach, which means quantifiable harm.
Damages can include tangible losses like:
- Additional medical bills and the cost of future care.
- Lost wages and reduced earning capacity.
They also include non-economic losses, such as pain, suffering, and loss of enjoyment of life.
The Cornerstone of Proof: Expert Testimony
In nearly all Washington medical malpractice cases, the complexity of medical science often exceeds the understanding of the average person or a jury. Because of this, Washington courts require an expert witness to explain two of the most vital elements: the standard of care and causation.
What an Expert Witness Provides
An expert witness is another doctor or health professional who practices in the same field as the defendant. They must:
- Define the Standard of Care: The expert reviews your medical records and testifies about what a reasonably prudent provider in that field should have done.
- Identify the Breach: They clearly explain how the defendant failed to meet the standard, providing an authoritative opinion.
- Establish Causation: The expert then connects the defendant’s breach directly to your injury, testifying that the failure to meet the standard of care more likely than not caused your harm.
Without a qualified expert, the core of your case, proving a breach of the standard of care and linking it to your injury, cannot legally move forward in the court system, including at the Whatcom County Superior Court in Bellingham.
Evidentiary Documents: The Paper Trail
Before you ever speak to an expert, the evidence is in the paperwork. Collecting a complete record of your care is essential.
- Comprehensive medical records are the single most important piece of evidence. It includes all doctors’ notes, test results (such as X-rays, MRIs, and lab reports), nurses’ notes, operative reports, and medication charts. A discrepancy or missing note in these records often reveals a breach.
- Informed Consent Forms: These documents outline the risks and alternative treatments discussed with you by the provider. Under the law, a separate cause of action exists if a provider failed to inform you of a material risk that a reasonably prudent patient would attach significance to before consenting to treatment.
- Medical Bills and Receipts: These prove the financial toll of your injury, establishing the extent of your damages.
