What Is Medical Malpractice?

Medical malpractice occurs when medical care deviates from accepted medical standards and procedures and causes injury or death. Typically, accusations revolve around the failure to care for a patient at the degree that would be expected by another patient in the same conditions. These cases are complex with tons of paperwork and are aggressively defended by insurance companies.

Pennsylvania medical malpractice lawyers recognize that when doctors, nurses, hospitals, and other healthcare providers fail to meet professional standards, patients suffer serious consequences. Medical errors may create additional medical expenses, rehabilitation costs, lost income, permanent disabilities, and emotional trauma.

Under Pennsylvania law, a medical malpractice lawsuit may be filed by the injured patient or, in cases involving wrongful death, by surviving family members including the spouse, children, or parents of the deceased. If the patient is a minor or incapacitated, a legal guardian or representative may bring the claim. These lawsuits must comply with Pennsylvania’s Certificate of Merit requirement, which requires an expert medical professional to certify that the case has merit before proceeding.

Our Philadelphia trial lawyers work with medical experts to establish liability and demonstrate the full impact of medical negligence.

Examples of Medical Malpractice Errors

While the medical field is usually quite competent in treating patients, here are some examples of what can go wrong:

  • Misdiagnosis of a serious condition that led to long-term health consequences
  • Surgical wrong-site or wrong-procedure error
  • Negligent prenatal care or errors in the delivery room
  • Medication improper dosages
  • Anesthesia mistakes leading to brain injury or cardiac events
  • Failure to properly monitor patients during or after treatment
  • Infections caused by unsanitary conditions
  • Failure to obtain informed consent
  • Violations of the HIPPA medical privacy laws

GSO medical malpractice lawyers work with expert witnesses and investigators to determine fault and get fair compensation without high-pressure settlement tactics from insurance companies.

Generally, Pennsylvania law specifies that medical malpractice claims must be filed within two years from the date the injury was discovered or should have been discovered. Some cases involve delayed discovery of malpractice, situations where the full extent of harm was not immediately apparent, or circumstances where the healthcare provider concealed their negligence. In these situations, the statute of limitations may be impacted by when you discovered that malpractice occurred.

Additional factors can also influence the filing deadline, including whether the claim involves a minor patient, a government hospital, or foreign objects left in the body during surgery. Claims involving minors may have extended deadlines, as well as cases against government-operated facilities may require special notice and shorter timeframes. Pennsylvania also has a statute of repose that generally bars claims filed more than seven years after the malpractice occurred.

If your injury resulted from a deviation from accepted medical standards, you may have a valid claim. An attorney review is the best first step since each patient’s experience is different.

When I reached out to Max Goldberg after my car was totaled by another driver and my elderly mom was severely injured, I was beside myself. He calmed my fears and handled every detail with professionalism and kindness. He was patient with my many questions, handling both of our case with compassion. I put my trust in Max and he did not let me down!

I honestly didnt know what to expect when I had to seek legal council. I was fortunate enough to have Bill Coppol as my lawyer. From day one Bill was thoughtful, transparent and caring. I never felt for one moment that he did not have my best interests at heart. I highly recommend assure you that you will be in good hands. Also shout out to an unsung hero. Mike is a paralegal here and he was with me for select appointments and was always on top of communication and information gathering.
