Significant Medication Error From Incorrect Divalproex Dose
Summary
The deficiency involves the facility’s failure to ensure a resident was free from significant medication errors, specifically related to incorrect dosing of Divalproex DR. Clinical record review showed that the resident was being seen repeatedly by advanced practice providers in June for muscle weakness and weakness. A nurse practitioner documented on 6/23/25 that the resident’s weakness was found to be due to an incorrect medication dose being dispensed, noting a 500 mg dose instead of the ordered 250 mg. The physician’s order specified Divalproex DR 250 mg tablets, but the medication dispensed and administered was Divalproex DR 500 mg. Pharmacy records and interviews confirmed that on 5/18/25, the pharmacy dispensed 150 tablets of Divalproex DR 500 mg with a label instructing staff to give two tablets in the morning and three at bedtime, which did not match the physician’s order for 250 mg tablets. Nursing staff interviews indicated that nurses were expected to follow the facility’s medication administration policy, including verifying the right resident, right medication, right dose, and ensuring the medication card matched the MAR. The DON and multiple LPNs stated that if the pharmacy sent the wrong medication or if the milligrams did not match the MAR, nurses were expected to identify and correct the discrepancy, but this did not occur in this case. On 6/20/25, the resident was assessed by an LPN who initially stated she did not observe changes in condition, but her documentation reflected that the resident had altered mental status, and the resident’s mother requested hospital transfer. At the hospital, the discharge summary indicated that the resident’s motor weakness was possibly medication-induced, and lab results showed a valproic acid level of 115, above the normal range of 50–100. A physician assistant interviewed later confirmed that increased doses of Divalproex DR can cause drowsiness, muscle weakness, skin reactions, somnolence, nausea, and vomiting. These findings collectively demonstrate that the resident received an incorrect, higher dose of Divalproex DR over time, constituting a significant medication error that resulted in harm.
