Most Frequent Types of Medical Errors

  • Medication Errors: These mistakes happen during prescribing, dispensing, or administering drugs. Examples include giving the wrong dose, the wrong drug, or failing to check for harmful drug interactions.
  • Diagnostic Errors: This category includes delayed, missed, or incorrect diagnoses. They often involve common conditions like infections, cancers, or vascular events.
  • Healthcare-Associated Infections (HAIs): Patients sometimes contract preventable infections while receiving treatment in a medical facility.
  • Surgical and Procedural Errors: These rare but serious events involve operating on the wrong body part or leaving surgical instruments inside a patient.
  • Communication Breakdowns: Failures during patient handoffs or poor documentation between medical staff can lead to subsequent treatment mistakes.
