Significant Medication Error from Oral Drugs Given via Midline Catheter
Summary
The deficiency involves the facility’s failure to ensure that a resident was free from significant medication errors when ordered oral medications were administered via an intravenous (IV) midline catheter instead of by mouth. Facility policy on medication administration required adherence to the six rights of medication administration, including the right route, and specified that medications be administered by licensed personnel in accordance with Pennsylvania regulations. Resident 2’s MDS indicated that the resident was cognitively intact, required staff assistance with daily care, and had diagnoses including atherosclerotic heart disease. The resident had a right upper arm midline catheter in place for IV medication administration, specifically for Zosyn. Physician orders for the resident included multiple oral medications: apixaban 5 mg by mouth twice daily for atrial fibrillation, gabapentin 100 mg two tablets by mouth three times daily for rheumatoid arthritis, magnesium oxide 400 mg by mouth twice daily for magnesium deficiency, potassium chloride ER 20 mEq by mouth three times daily for potassium deficiency, and midodrine 5 mg two tablets by mouth three times daily for hypotension. The resident also had an order for oral tablets to be crushed and mixed in pudding. On the evening medication pass, the 6:00 p.m. oral medications (Eliquis 5 mg, gabapentin 100 mg, magnesium oxide 400 mg, midodrine 5 mg, and potassium 20 mEq) were instead crushed, mixed with warm water, and administered through the resident’s right arm midline catheter. Multiple staff statements and interviews confirmed that an LPN crushed the resident’s ordered oral medications, dissolved them in water, and administered them via the midline using a normal saline flush syringe, rather than giving them orally as ordered. Another nurse became suspicious when the resident’s daughter questioned whether it was appropriate to put medications into the midline, and when attempts to infuse IV antibiotics and flush the midline were unsuccessful despite the LPN stating he had just flushed it. The LPN later admitted to several staff, including RNs, that he had crushed and administered the 6:00 p.m. oral medications through the midline catheter, stating he had made a mistake and was confused with administering medications through a gastric tube. Subsequently, the resident’s oxygen saturation remained between 85% and 87% on 12 liters of supplemental oxygen, the physician was notified, and the resident was transferred to the hospital, where emergency room evaluation revealed hyponatremia and otherwise stable condition. The physician documented that the resident had been given oral medications dissolved in water through the midline the previous evening and that the midline had since been removed.
