Medication Administration Errors with Enteral Feeds and Drug Interactions
Summary
The facility failed to prevent significant medication errors for three residents receiving enteral medications. During a medication pass observation, an LVN prepared and administered multiple medications for one resident, including ferrous sulfate liquid, multivitamins with minerals, phenytoin oral suspension, and crushed minocycline tablets. The resident had diagnoses including seizures, anemia, hemiplegia, and dependence on respiratory status, and the record showed the resident lacked the capacity to understand and make decisions. The resident’s care plan included seizure precautions and treatment for infection, and the physician orders included both phenytoin via g-tube and minocycline for 14 days. The resident was administered ferrous sulfate and minocycline together at the same scheduled medication time for 18 days. The DON stated there was a potential interaction between ferrous sulfate and minocycline and that they should not be given together because iron binds to minocycline. The consultant pharmacist and dispensing pharmacist both stated that minocycline and ferrous sulfate should be separated because they affect each other’s absorption. The resident’s MAR documented the concurrent administration of both medications during the identified period. The facility also failed to ensure enteral feedings were held before and after phenytoin administration for three residents receiving Dilantin via g-tube. For one resident, the LVN restarted the feeding pump after giving phenytoin and stated he was not sure whether feeding should be started immediately after administration. The DON stated the feeding must be held one hour before and one hour after phenytoin, but that this instruction was not included on the physician order or prescription label. For two other residents, the records showed active phenytoin and enteral feeding orders, and the DON stated there was no order to hold feedings before and after phenytoin administration. One resident’s Dilantin level was documented as low at 7.0 mcg/ml. The facility’s policy and a drug reference reviewed by the DON stated that phenytoin absorption is reduced with tube feeding and that feeds should be held around administration.
