Patients trust doctors, nurses, and other healthcare professionals to provide safe, competent medical care. While not every unexpected outcome is the result of negligence, preventable medical errors continue to be a significant cause of injuries and complications in the U.S.
These mistakes don’t always look the same. Some happen during surgery, others involve medications or missed diagnoses, and some result from simple communication failures between providers. Below are some of the errors that most often lead to medical malpractice claims.
Misdiagnosis and Delayed Diagnosis
Getting the right diagnosis is often the first step toward receiving effective treatment. When a healthcare provider makes a diagnostic error, the consequences can be serious.
A delayed or missed diagnosis can allow illnesses like cancer, stroke, heart disease, or severe infections to worsen. In some cases, early diagnosis could have prevented permanent complications or even saved a patient’s life. In other cases, a patient may undergo unnecessary treatment because the underlying condition wasn’t correctly identified in the first place.
Medication Errors
Medication mistakes can occur at nearly every stage of the treatment process. For example, a doctor may prescribe the wrong drug, a pharmacist may fill the wrong prescription, or a healthcare provider may administer medication incorrectly.
Some of the most common medication errors include:
- Prescribing the wrong medication
- Giving the wrong dosage
- Failing to recognize dangerous drug interactions or side effects
- Administering medication to the wrong patient
Even a seemingly minor mistake can lead to serious complications, especially when strong medications, like opioids, are involved.
Surgical Errors
Every surgery carries risks, but preventable errors are different from known complications. Patients shouldn’t suffer harm because basic safety protocols weren’t followed.
Examples of surgical mistakes include:
- Operating on the wrong body part
- Leaving surgical instruments inside a patient’s body
- Performing the wrong procedure
- Causing avoidable damage to nearby organs or nerves
These mistakes can lead to additional surgeries, longer recoveries, and lasting health problems.
Birth Injuries
Pregnancy and childbirth require careful attention from start to finish. Medical providers are responsible for monitoring both the mother and baby during labor and delivery and responding appropriately when complications arise.
Birth injury cases often involve issues such as delayed C-sections, failure to recognize fetal distress, or the improper use of delivery instruments. In some situations, these mistakes can have lifelong consequences.
Communication Breakdowns
Not every medical error is caused by a single bad decision. Sometimes the problem is that important information never reaches the right person.
A missed lab result, incomplete chart, poor communication during a shift change, or unclear discharge instructions can all affect a patient’s care. When providers aren’t working from the same information, mistakes become much more likely.
How Long Do I Have to File a Medical Malpractice Lawsuit?
If a medical error caused your injury, don’t assume you have unlimited time to take legal action. Every state sets deadlines for filing medical malpractice lawsuits.
For example, California typically requires these claims to be filed within one year of discovering the injury or three years from the date the injury occurred, whichever comes first, although exceptions may apply. Florida generally has a two-year deadline, which differs from California’s and can also vary depending on the facts of the case.
Because the procedures and statutes of limitations vary by state, it’s a good idea to speak to a local medical malpractice lawyer to determine the appropriate deadline for your case.
What Should You Do if You Suspect a Medical Error?
If you think a healthcare provider’s mistake caused your injury, prompt action may help protect both your health and your legal rights.
Consider taking the following steps:
- Seek appropriate medical treatment or a second opinion from a different provider.
- Request copies of your medical records.
- Keep documentation of your expenses and treatment.
- Write down what happened while the details are still fresh.
- Speak with an experienced medical malpractice attorney to determine whether you may have a valid claim.
Not every unexpected medical outcome is the result of malpractice. However, when a healthcare provider fails to meet the accepted standard of care and that failure causes harm, you may have legal options worth exploring.
