Failure to Follow Physician Orders for Warfarin Administration
Summary
A deficiency occurred when staff failed to follow physician orders for warfarin (Coumadin) administration for a resident with a history of atrial fibrillation, dementia, and a prosthetic heart valve. The resident had a prescribed warfarin dose of 5.5 mg daily, with a therapeutic INR goal of 2.5 to 3.5. Despite an elevated INR result of 6.7, a physician order was given to hold the warfarin dose and decrease the daily dose to 5.0 mg starting the following day. However, the Medication Administration Record (MAR) documented that the resident continued to receive 5.5 mg of warfarin on the day of the elevated INR and for the next three days. The resident's INR continued to rise, reaching 12.4 on a subsequent test. The resident was then admitted to the hospital with pneumonia, urinary tract infection, and a critically high INR of 13, requiring treatment with Vitamin K. Interviews with staff revealed confusion and lack of clarity regarding the process for holding medications, transcribing physician orders, and updating the MAR. Staff members were unsure about how to properly document and communicate hold orders, and there was inconsistency in the understanding of who was responsible for entering and confirming medication changes in the electronic health record system. The facility's policy required clear documentation and adherence to physician orders for anticoagulant use, including holding medications when lab values were outside the therapeutic range. Despite this, the resident received unnecessary doses of warfarin after orders to hold the medication, resulting in a significant medication error and an Immediate Jeopardy situation for the resident's health and safety.
