The resident, who takes Coumadin to prevent strokes caused by atrial fibrillation, should have received the blood thinner daily. Instead, the patient missed doses on August 12, August 22, and September 2, federal inspectors found during a September complaint investigation.
Blood tests revealed the consequences. The patient's INR levels — which measure blood clotting time — stayed dangerously low for weeks. Normal therapeutic range runs between 2.0 and 3.0 for atrial fibrillation patients. This resident's levels dropped as low as 1.3 on September 18, nearly a full point below the safe minimum.
APRN #2 acknowledged the pattern during an interview with inspectors on September 18. "From August 12 through September 15, Resident #2 missed Coumadin doses and should not have missed any doses," she told investigators. She also admitted "the INR was not maintained within the therapeutic range in accordance with physician orders."
The most serious error occurred on September 15. APRN #2 intended to increase the patient's daily Coumadin dose from 5 mg to 6.5 mg — a standard adjustment when blood tests show inadequate clotting prevention. Instead, she entered a new order for just 1.5 mg, cutting the dose by more than two-thirds.
"APRN #2 stated it was an error on her part," inspectors wrote.
The mistake forced a dangerous scramble to correct the patient's blood levels. On September 18, with the INR at 1.3, new orders called for a massive 10 mg dose — nearly seven times the mistaken 1.5 mg order. The next day, another 10 mg dose was needed when the level only reached 1.8.
By September 19, the patient required 10 mg again, followed by 6 mg doses for two days. The aggressive dosing finally pushed the INR to 3.3 on September 22 — now slightly above the safe range.
MD #2 explained the stakes during his interview with inspectors on September 23. "Maintaining the INR results can be tricky and it is better to be high results than low," he said. Low INR levels mean blood clots too easily, raising stroke risk for atrial fibrillation patients.
The physician confirmed basic medication protocols weren't followed. "The orders should have been transcribed accurately, and a resident on Coumadin should receive Coumadin daily, unless contraindicated such as the INR too high," he told inspectors.
Records show the patient's INR fell below therapeutic levels on August 18, August 19, September 2, September 12, September 15, September 18, and September 19. Only once during this period — on August 16 — did blood tests show adequate clotting prevention, yet no new Coumadin orders were obtained even then.
The facility's own Coumadin Protocol Policy requires staff to maintain a tracking log showing INR dates and results, current and new medication orders, next blood test dates, and physician notifications. The policy also mandates that "the INR therapeutic range must be determined" for each patient.
For patients with atrial fibrillation, that determination can mean the difference between a stroke and continued independence. Coumadin works by interfering with vitamin K-dependent clotting factors, requiring careful monitoring to prevent both dangerous clots and excessive bleeding.
The September inspection focused on a complaint about medication management. Inspectors classified the violation as causing "minimal harm or potential for actual harm" affecting "few" residents.
APRN #2's acknowledgment that she signed tracking forms throughout the period suggests the monitoring system was in place but failed to prevent the dosing errors. Each time blood tests revealed inadequate clotting prevention, new orders were eventually obtained — but often days later, leaving the patient vulnerable.
The resident's month-long exposure to stroke risk illustrates how medication errors can compound over time in nursing homes. What began as missed doses in August escalated into a major dosing mistake in September, requiring emergency interventions to restore safe blood levels.
