Significant Oxycodone Dosing Error Due to Failure to Verify Tablet Strength and Orders
Penalty
Summary
The deficiency involves the facility’s failure to prevent a significant medication error for a resident receiving opioid therapy for chronic pain. The resident had moderate cognitive impairment and multiple diagnoses including anxiety, COPD, depression, heart failure, and respiratory failure, and was care planned for chronic pain with interventions to monitor for opiate side effects. The physician’s order, in place since early March, specified Oxycodone HCl 15 mg every six hours. Initially, the pharmacy dispensed 5 mg tablets with instructions on the medication card and controlled drug record to administer three tablets every six hours to equal the ordered 15 mg dose, and staff followed this regimen. On a later date, the pharmacy delivered a new supply of Oxycodone HCl as 15 mg tablets, with the new controlled drug record and medication card directing staff to administer one tablet every six hours. However, on the afternoon when the new card arrived, a CMA completed the remaining 5 mg tablets from the old card (two tablets) and then took one 15 mg tablet from the new card, resulting in a 25 mg dose instead of the ordered 15 mg. The following morning, an LPN documented administering three 15 mg tablets (45 mg total) and signed the controlled drug record and MAR as if the ordered dose had been given. Later that same day at midday, the CMA again documented administering three 15 mg tablets (another 45 mg total) and signed the MAR as if the ordered dose had been provided. Progress notes later that day documented the resident appearing pale, with garbled speech, confusion, and pinpoint pupils, and then later reaching out to grab at the air, laughing about it, with pupils measured at 1 mm and intermittent drowsiness, though easily arousable. An RN associated with the resident’s primary care provider assessed the resident that afternoon and found the resident drowsy but responsive, with a contracted arm, shakiness, and pinpoint pupils, and reported that the primary care provider considered possible opioid overdose among other differential diagnoses. Facility staff interviews revealed that the CMA and LPN continued to give three tablets because that had been the prior practice with the 5 mg tablets, did not verify the tablet strength or compare the new medication card to the MAR, and that there was no formal process in place to notify staff of dose changes when new medication cards with different tablet strengths were received.
