Prescription Medication Errors When They Are “Medical Malpractice”
Published .
A prescription or medication error is not automatically medical malpractice. The key questions are who made the error, what professional or legal standard applied, whether the conduct fell below that standard, and whether the error caused actual injury. An error that is caught before it causes harm may warrant correction or reporting, but a negligence claim generally requires proof of injury and causation.
Where medication errors occur
Errors can arise when a clinician selects a medication or dose, overlooks an allergy or material interaction, fails to adjust for a patient’s condition, gives inadequate monitoring instructions, or fails to respond to a known adverse reaction. A hospital or other care facility may be responsible when a nurse administers the wrong medication, dose, or route, or when a system failure allows an error to pass through required safety checks. A retail pharmacy may misread or mis-enter an order, dispense the wrong drug or strength, label it incorrectly, or give directions inconsistent with the prescription.
The legal theory depends on the actor and the nature of the mistake. A prescriber, nurse, hospital, or other statutorily covered health care provider may face a medical-malpractice claim when the alleged error concerns professional care. Claims involving a defective drug, packaging, or warning may instead or additionally raise product-liability or warranty issues. A pharmacy’s dispensing mistake is commonly analyzed as negligence, but the facts may support other theories. Each theory has separate elements and defenses.
Maryland’s special malpractice process and pharmacy claims
Maryland’s Health Care Malpractice Claims Act applies to qualifying claims for medical injury against a health care provider as defined by statute when damages sought exceed the District Court’s concurrent jurisdictional limit. The Act requires the claimant to begin in the Health Care Alternative Dispute Resolution Office and generally requires a certificate of a qualified expert. See Md. Code, Courts & Judicial Proceedings §§ 3-2A-01, 3-2A-02, and 3-2A-04. In Mancuso v. Giant Food, Inc., the Court of Appeals of Maryland (now the Supreme Court of Maryland) held that pharmacists and a retail pharmacy were not included in the statutory definition of health care provider and that a claim based on a pharmacist’s dispensing error was not subject to that Act’s mandatory arbitration process. 327 Md. 344, 609 A.2d 332 (1992). Claims against a hospital or a separately listed provider, including potential vicarious-liability theories, require their own analysis; do not assume that Mancuso removes every medication-error case from HCADRO.
Evidence that can identify what happened
Preserve the prescription bottle, packaging, medication and remaining pills, written instructions, pharmacy receipt, and any communication about the drug. Relevant records may include the original prescription or electronic order, dispensing and verification logs, refill history, medication administration records, allergy and medication lists, clinical notes, and pharmacy policies. Identify the drug and actual dose taken, when it was taken, who discovered the error, the symptoms that followed, and subsequent treatment. Expert review may be needed to establish the applicable standard of care and medical causation.
