Failure to Monitor Anticoagulant Therapy
Summary
The facility failed to ensure that Protimes/INRs were completed as ordered for a resident receiving Coumadin, an anticoagulant medication. The resident, who was admitted with a diagnosis of atrial fibrillation, had an order for weekly Protimes/INRs to be drawn on Mondays. However, the first Protime/INR in July was not completed until July 15, resulting in a critical INR value of 6.75, which was significantly above the therapeutic range of 2.0 to 3.0. Despite the critical value, the facility did not draw the Protime/INR as ordered on July 16, and the resident continued to receive Coumadin without appropriate monitoring. Subsequent lab results on July 18 showed even higher critical values, prompting the administration of Vitamin K to counteract the elevated INR. The resident was sent to the hospital on July 19 due to the supratherapeutic INR levels, although no active bleeding was observed. The hospital repeated the INR, which had decreased to 4.5, and the resident was discharged back to the facility with instructions to hold Coumadin and recheck the INR within 24 to 48 hours. Despite these instructions, the facility's documentation and administration of Coumadin remained inconsistent, with missed doses and incorrect documentation on the MAR. Throughout July and August, the facility continued to struggle with maintaining consistent and accurate monitoring of the resident's Protime/INR levels. Orders for Coumadin dosages were frequently changed, and lab draws were not consistently performed as scheduled. The facility's transition to a new electronic medical record system contributed to documentation issues, as noted by the Corporate Nurse Consultant. The facility pharmacy consultant and the resident's physician both acknowledged the problems with lab timing and documentation, but no harm was reported to have come to the resident from the elevated Protimes.
