Overview
This lecture covers high alert (high risk) medications, their characteristics, examples, and strategies to minimize medication errors in pharmacy practice.
Definition and Importance of High Alert Medications
- High alert medications have an increased risk of causing significant patient harm if used in error.
- These drugs may not be more likely to cause errors but have severe consequences if a mistake occurs.
- Extra precautions are needed when handling high alert medications.
High Alert vs. Narrow Therapeutic Index (NTI) Drugs
- NTI drugs are those where small dosing differences can cause severe failures or adverse reactions.
- Many high alert medications also have a narrow therapeutic index.
Organizations Guiding High Alert Medication Safety
- The Institute for Safe Medication Practices (ISMP) provides lists of high alert medications for various pharmacy settings.
- The Joint Commission (JCAHO or JC) sets standards and requires facilities to manage high alert medications through defined processes.
Common Classes of High Alert Medications
- Insulins and sulfonylureas: potent blood sugar lowering agents; errors can cause coma or death.
- Anticoagulants (blood thinners): increase bleeding risk; errors can be fatal.
- Opioid pain medications: risk of respiratory depression and death.
- Chemotherapy agents: high toxicity, can damage healthy cells.
- Neuromuscular blockers: can cause paralysis or permanent injury.
- IV beta blockers, antiarrhythmics, immunosuppressants, intrathecal/epidural drugs, pediatric liquids, anesthetics, radiocontrast agents.
Specific High Alert Medications
- Epinephrine, epoprostenol, vasopressin, sodium nitroprusside: greatly affect blood pressure and heart rate.
- IV oxytocin: induces labor; requires precise dosing.
- Injectable electrolytes (potassium, sodium chloride >0.9%, magnesium sulfate): risk of severe side effects if misused.
- Insulin U-500 (very concentrated).
- Methotrexate, promethazine injection, opium tincture: risk of serious adverse effects.
- Seizure medications: carbamazepine, lamotrigine, phenytoin, valproic acid.
Joint Commission’s Five High Alert Medications
- Insulin
- Opiates and narcotics
- Injectable potassium concentrates
- IV anticoagulants (e.g., heparin)
- Sodium chloride solutions above 0.9%
Strategies to Prevent High Alert Medication Errors
- Educate staff about high alert drugs.
- Use auxiliary “high alert” labels.
- Limit access to certain medications.
- Require independent double checks by two people.
- Use technology for automated double checks on drug, dose, patient, time, and route.
Key Terms & Definitions
- High Alert Medication — medication with a higher risk of causing serious harm if used in error.
- Narrow Therapeutic Index (NTI) Drug — drug where small dose changes can cause serious adverse effects.
- ISMP — Institute for Safe Medication Practices, provides safety resources.
- The Joint Commission (JCAHO, JC) — accredits healthcare organizations, sets safety standards.
- Independent Double Check — two individuals independently verify medication accuracy.
Action Items / Next Steps
- Review ISMP’s and The Joint Commission’s high alert medication lists.
- Implement strategies for safe handling of high alert medications in practice.
- Educate yourself and staff on medication safety procedures.
