Significant Medication Errors With Time-Sensitive Parkinson’s Medications and Incorrect Insulin Dose
Summary
Residents were not free from significant medication errors. One resident with Parkinson’s disease and intact cognition had physician-ordered carbidopa/levodopa through a PEG tube every four hours and clonazepam for tremors, but the medication administration record showed multiple late administrations of both medications over the review period, along with one missed documented dose of carbidopa/levodopa. The resident was observed with tremors, soft speech, slow speech, and repeated tapping of his right foot, and he reported that when his medications were late he developed sweating, worse tremors and jerking movements, and difficulty using his urinal because of the increased movements. The resident also stated that his medications were often late, especially at night. The resident’s physician and the consultant pharmacist both stated that carbidopa/levodopa and clonazepam were to be given on schedule, with the physician identifying late or missed doses as significant medication errors. The physician also stated that the timing of these medications was based on the resident’s symptoms and that inconsistent administration could affect interpretation of his clonazepam gradual dose reduction. Facility leadership acknowledged that the resident’s medications were expected to be administered as scheduled and that late administration could alter the outcome of the gradual dose reduction attempt. A second resident with type 2 diabetes and intact cognition received an incorrect dose of Humalog insulin after an LPN entered the roommate’s blood sugar value into the resident’s EMR. The resident’s actual blood sugar was 122, which did not require insulin, but the LPN documented the roommate’s blood sugar of 258 and administered 7 units of Humalog based on that incorrect value. The LPN stated she was rushing while working with an RN in training and realized immediately that she had given insulin based on the wrong resident’s blood sugar. The resident’s physician, daughter, and DON were notified, and the resident’s blood sugars were monitored afterward. The consultant pharmacist stated that giving 7 units of insulin when the blood sugar was 122 could be considered a significant medication error.
