Significant Insulin Administration Errors
Summary
The facility failed to ensure residents were free from significant medication errors involving insulin administration. One resident with diabetes mellitus, long-term insulin use, glaucoma, scoliosis, and chronic lower back pain had physician orders for blood glucose monitoring before meals and at bedtime and for three units of rapid-acting insulin aspart before breakfast. On the morning of the event, the assigned RN did not check the resident’s blood sugar before breakfast and did not administer the ordered insulin dose. Later that day, the resident’s blood glucose was documented at 600 mg/dl, and the RN acknowledged she had gotten behind on medication administration and missed the blood glucose check and insulin dose. A second resident with diabetes, prior stroke-related right-sided weakness, and significant assistance needs for transfers, bathing, toileting, and lower body dressing had an order for three units of insulin glargine daily. After obtaining the resident’s blood sugar of 127 mg/dl, the RN administered insulin but later realized she had given 30 units instead of the ordered 3 units. The resident’s blood glucose subsequently dropped to 60 mg/dl, and the resident became lethargic and had difficulty staying awake. Nursing notes documented repeated blood glucose monitoring and treatment after the overdose, and the RN stated she had dialed in 30 units on the insulin pen before administering it. Record review and staff interviews confirmed both events occurred as documented. The first RN stated she was working on a different floor than usual and had a large number of residents to check that morning, which contributed to the missed insulin administration. The second RN stated it was her first time administering insulin to that resident and that she realized the dose error only after returning to chart the medication. The DON, PCP, and MD were interviewed and confirmed the events and the significance of the insulin administration errors.
