What Counts as Medical Negligence in Washington?
Not every medical mistake, complication, or poor outcome is medical malpractice. In Washington, the central question is whether a healthcare provider failed to meet the accepted standard of care and whether that failure caused the patient’s injury.
That sounds straightforward, but medical negligence cases are rarely simple. Doctors can make reasonable medical decisions that lead to bad outcomes, while seemingly small errors can sometimes cause catastrophic harm.
Understanding the difference starts with Washington’s legal standard.
Key takeaway: A bad result alone doesn’t establish medical negligence. A potential claim generally requires evidence that a healthcare provider’s care fell below the standard expected of a reasonably prudent provider in Washington under similar circumstances and that the failure caused harm.

What Is Medical Negligence Under Washington Law?
Washington law addresses injuries caused by healthcare under Chapter 7.70 RCW.
Under RCW 7.70.040, a patient pursuing a claim based on a healthcare provider’s failure to follow the accepted standard of care generally must establish that:
- The provider failed to exercise the degree of care, skill, and learning expected of a reasonably prudent healthcare provider in Washington under the same or similar circumstances; and
- That failure was a proximate cause of the patient’s injury.
In practical terms, the question isn’t simply whether a doctor or hospital made a mistake.
The questions are:
- What should a reasonably prudent provider have done under the circumstances?
- What did the provider actually do or fail to do?
- Did that difference cause or materially contribute to the patient’s injury?
Medical records, testimony from qualified medical experts, diagnostic studies, imaging, medication records, hospital documentation, and the timeline of the patient’s treatment can all become important when answering those questions.
What Are Common Examples of Medical Negligence?
Medical negligence can occur at nearly any stage of diagnosis, treatment, surgery, hospitalization, or follow-up care.
Common examples include:
Failure to Diagnose or Delayed Diagnosis
A missed diagnosis isn’t automatically malpractice. The issue is whether another reasonably prudent provider under similar circumstances should have recognized the condition or taken additional steps to diagnose it.
Potential examples include:
- Failing to recognize symptoms of stroke, heart attack, sepsis, or cancer
- Ignoring abnormal laboratory or imaging results
- Failing to order appropriate diagnostic testing
- Failing to refer a patient to a specialist
- Failing to follow up on abnormal test results
- Diagnosing a serious condition only after the patient’s treatment options have become more limited
The medical and legal question often becomes whether an earlier diagnosis probably would have changed the patient’s outcome.
Surgical Errors
A surgical complication doesn’t necessarily mean the surgeon was negligent. Surgery carries recognized risks even when everyone involved follows the appropriate standard of care.
Potential negligence may involve:
- Operating on the wrong body part
- Performing the wrong procedure
- Leaving a surgical instrument or foreign object in the patient
- Injuring an organ, nerve, or blood vessel through substandard technique
- Failing to recognize or respond appropriately to a surgical complication
- Performing an unnecessary procedure
- Failing to provide appropriate postoperative monitoring
The circumstances surrounding the procedure and the medical response afterward can be just as important as the initial surgical injury.
Medication and Prescription Errors
Medication negligence may involve physicians, nurses, pharmacists, hospitals, or a combination of providers.
Examples can include:
- Prescribing the wrong medication
- Administering the wrong dose
- Failing to account for a dangerous drug interaction
- Giving medication intended for another patient
- Failing to consider a documented allergy
- Failing to monitor a patient taking a high-risk medication
Whether the error constitutes malpractice depends on the applicable standard of care and whether it caused injury.
Failure to Monitor or Respond to a Patient's Deterioration
Hospitals and healthcare providers have responsibilities that continue after a diagnosis or procedure.
A claim may involve a failure to recognize and respond appropriately to:
- Falling oxygen levels
- Signs of internal bleeding
- Changes in blood pressure or heart rate
- Abnormal laboratory findings
- Neurological changes
- Infection or sepsis
- Postoperative complications
- Signs of compartment syndrome or other medical emergencies
Sometimes the negligence isn’t the first medical event. It’s the failure to recognize that something has gone wrong and intervene before the patient’s condition becomes significantly worse.
Birth and Labor Delivery Negligence
Obstetric and neonatal negligence cases may involve failures before, during, or immediately after delivery.
Potential issues include:
- Failure to properly monitor fetal distress
- Delayed emergency C-section
- Failure to respond to abnormal fetal heart-rate patterns
- Improper management of delivery complications
- Delayed treatment of maternal complications
- Failure to recognize oxygen deprivation or other neonatal emergencies
Because many birth injuries can also occur without negligence, these claims generally require detailed review by qualified medical professionals.
Hospital and System Failures
Not every medical negligence case is solely about one doctor’s decision.
Hospitals and healthcare systems may also face allegations involving:
- Unsafe staffing
- Communication failures
- Inadequate supervision
- Poor patient handoffs
- Failure to communicate abnormal test results
- Medication administration failures
- Inadequate policies or procedures
- Credentialing or institutional safety issues
Determining responsibility often requires looking beyond one provider and examining how care was delivered across the entire medical team.
What Does Not Automatically Count as Medical Negligence?
This distinction is important.
A Bad Medical Outcome
A treatment can fail even when the provider acted appropriately.
A Known Complication
Many medical procedures involve unavoidable risks. Experiencing a recognized complication doesn’t by itself establish that anyone was negligent.
A Difference in Medical Judgment
Two competent physicians may reasonably choose different treatment approaches. A different medical decision isn’t necessarily substandard care.
A Medical Error That Didn't Cause the Injury
Even when a provider made a mistake, a malpractice claim generally requires evidence connecting that failure to the patient’s injury.
This issue of causation is one of the most important and frequently contested parts of a Washington medical negligence case.
How Do You Prove Medical Negligence in Washington?
Medical malpractice cases usually require a detailed investigation of both the medicine and the law.
1. Establish What the Standard of Care Required
The first question is what a reasonably prudent provider in the same profession or specialty would have done under similar circumstances.
2. Compare the Required Care With What Actually Happened
Medical records can help establish what providers knew, what tests were ordered, what treatment was provided, when decisions were made, and how the patient’s condition changed.
3. Determine Whether the Failure Caused the Injury
Identifying a medical error isn’t enough.
The evidence must connect the provider’s failure to the harm suffered by the patient.
For example, if a cancer diagnosis was delayed, the issue may be whether an earlier diagnosis probably would have allowed more effective treatment or prevented the disease from progressing.
4. Document the Harm Caused
A medical negligence claim may involve losses such as:
- Additional medical treatment
- Future medical and rehabilitation needs
- Disability
- Lost wages
- Loss of earning capacity
- Physical pain
- Emotional suffering
- Loss of independence
- Wrongful death damages when negligence causes a fatal injury
The damages available depend on the facts of the individual case.
Is Expert Testimony Required in a Washington Medical Malpractice Case?
In most Washington medical negligence cases, qualified expert testimony is important and generally required to establish the applicable standard of care and medical causation.
Medicine involves questions that ordinarily fall outside the knowledge of a judge or jury. A qualified expert can explain what the provider should have done, how the care departed from the appropriate standard, and whether that departure caused the patient’s injury.
The appropriate expert depends on the medical issues involved. An allegation involving orthopedic surgery, for example, may require different expertise than a claim involving emergency medicine, radiology, obstetrics, oncology, or nursing care.
What Is the Difference Between Medical Negligence and Medical Malpractice?
The terms are often used interchangeably.
Medical negligence generally refers to substandard medical care or a negligent act or omission. Medical malpractice commonly refers to the legal claim that can arise when negligent medical care causes a patient injury.
For someone who has been harmed, the terminology is less important than the underlying questions:
Did the healthcare provider fail to meet the applicable standard of care, and did that failure cause the injury?
Can Lack of Informed Consent Lead to a Claim?
Potentially.
Washington law separately addresses claims involving a healthcare provider’s failure to obtain informed consent.
Under RCW 7.70.050, these claims can involve allegations that a provider failed to disclose material information about a proposed treatment and that a reasonably prudent patient would not have consented to the treatment if properly informed.
Informed consent claims are legally distinct from many traditional standard of care negligence claims and depend heavily on the particular facts surrounding the treatment and information provided.
Who Can Be Responsible for Medical Negligence?
Medical malpractice cases aren’t limited to physicians.
Depending on the circumstances, potentially responsible parties may include:
- Physicians
- Surgeons
- Nurses
- Nurse practitioners
- Physician assistants
- Pharmacists
- Hospitals
- Clinics
- Healthcare systems
- Other licensed healthcare providers
Some cases involve multiple providers or institutions.
Identifying every potentially responsible party can be particularly important in cases involving hospital care, surgery, emergency treatment, or multiple specialists.
How Can You Tell If You May Have a Medical Negligence Case?
You don’t need to know exactly what went wrong before speaking with an attorney.
Some circumstances that may justify a closer investigation include:
- Your condition unexpectedly deteriorated after treatment.
- A second physician tells you the earlier treatment was inappropriate.
- An abnormal test result wasn’t communicated or followed up.
- You were discharged and quickly required emergency treatment or readmission.
- A diagnosis was made only after repeated visits for the same symptoms.
- You suffered a new injury during surgery or hospitalization.
- A serious complication wasn’t recognized or treated promptly.
- Your medical records appear inconsistent with what you were told.
- A provider acknowledged that something unexpected went wrong.
- A loved one suffered a preventable death after apparent delays or failures in medical care.
None of these facts automatically proves malpractice. They can, however, provide reasons to investigate the care more closely.
What Evidence Is Important in a Medical Negligence Case?
Depending on the circumstances, an investigation may involve:
- Complete medical records
- Physician and nursing notes
- Diagnostic imaging
- Laboratory results
- Medication administration records
- Operative reports
- Pathology reports
- Fetal monitoring strips
- Referral records
- Electronic health-record timestamps
- Hospital policies and procedures
- Billing records
- Records from subsequent treating physicians
- Testimony from qualified medical experts
One of the first steps in evaluating a potential claim is often reconstructing exactly what happened and when.

How Long Do You Have to File a Medical Malpractice Claim in Washington?
Washington imposes strict deadlines on medical negligence claims.
Under RCW 4.16.350, a professional negligence action involving healthcare generally must be commenced within three years of the act or omission or within one year after the patient discovered, or reasonably should have discovered, that the injury was caused by the act or omission, whichever period expires later.
Washington law also contains an eight-year statute of repose, subject to specific exceptions.
Because calculating the deadline can depend on the facts of the case, patients shouldn’t assume they have a particular amount of time without obtaining legal advice.

What Should You Do If You Suspect Medical Negligence?
If you believe you or a family member was seriously harmed by medical negligence:
- Get the medical care you need. Your health comes first.
- Request and preserve your medical records.
- Write down what happened while the timeline is still fresh.
- Keep medical bills, correspondence, photographs, and other documentation.
- Avoid assuming that a bad outcome proves negligence.
- Consider having the medical care independently reviewed.
- Speak with an experienced Washington medical malpractice attorney before important filing deadlines expire.
Medical malpractice claims frequently turn on details contained in medical records and expert analysis that aren’t obvious to the patient immediately after the injury.

Washington Medical Negligence FAQs
What qualifies as medical negligence in Washington?
A potential medical negligence claim may exist when a healthcare provider fails to exercise the care, skill, and learning expected of a reasonably prudent Washington provider under similar circumstances and that failure causes injury.
Does a misdiagnosis count as medical malpractice?
Sometimes. A misdiagnosis alone doesn't establish malpractice. The issue is whether a reasonably prudent provider should have reached the correct diagnosis or taken additional diagnostic steps and whether the error caused the patient's injury.
Is every surgical complication malpractice?
No. Complications can occur even when appropriate care is provided. A malpractice claim may exist when the complication was caused by substandard care or when providers negligently failed to recognize and treat it.
Can a hospital be liable for medical negligence?
Potentially. Depending on the circumstances, a case may involve negligent care by hospital employees or institutional failures involving staffing, supervision, communication, policies, credentialing, or patient safety.
Do I need a medical expert to prove malpractice?
Medical expert testimony is generally required in Washington malpractice cases involving questions about the standard of care and medical causation, although whether particular expert testimony is necessary depends on the issues in the case.
Is a bad medical outcome enough to file a malpractice claim?
No. An unexpected or poor medical outcome doesn't by itself establish negligence. There must generally be evidence that the provider failed to meet the applicable standard of care and that the failure caused injury.
