High-Alert/High-Risk Medications (PCTB PTCE Pharmacy Technician Test Prep)
Summary
This video explains high alert medications, drugs with a high risk of patient harm if misused. It differentiates them from Narrow Therapeutic Index (NTI) drugs, noting many high alert drugs are also NTI. The Institute for Safe Medication Practices (ISMP) and The Joint Commission (JC) are highlighted as organizations providing lists and guidance. Common classes like insulins, anticoagulants, opioids, concentrated electrolytes, and neuromuscular blockers are detailed, along with their risks. Strategies to mitigate errors, including staff education, labeling, access control, independent double checks, and technology, are discussed.
Key Insights
Many high alert medications are also NTI drugs, explaining their inherent risk.
A key reason that many high alert medications can cause significant harm or injury if used in error is that they often have a narrow therapeutic index. This means even a small change in dose or blood concentration can lead to very significant undesired effects.
Injectable concentrated electrolytes (potassium, sodium chloride >0.9%) can cause fatal rhythm changes or brain damage.
Concentrated injectable electrolytes such as potassium chloride and sodium chloride solutions greater than 0.9% (hypertonic saline) are high alert. Injectable potassium concentrates can lead to fatal hyperkalemia and cardiac rhythm changes. Hypertonic sodium chloride solutions can cause brain damage due to severe hypernatremia.
Concentrated electrolytes pose risks of fatal hyperkalemia or brain damage from hypernatremia.
Injectable potassium concentrates can cause fatal hyperkalemia (high blood potassium), leading to dangerous heart rhythm changes. Sodium chloride solutions above 0.9% can cause severe hypernatremia (high blood sodium), leading to brain damage and death.

Definition and Characteristics of High Alert Medications
High alert medications pose increased risk of significant patient harm if misused or an error occurs.
High alert or high risk medications (HAMs) are drugs that have an increased risk of causing significant patient harm or injury when misused or used in error. While not necessarily more prone to errors, the consequences of a mistake can be life-threatening and permanent.
High alert medications require extra precautions to minimize the risk of errors.
Because an error with high alert medications can have severe consequences, these drugs require extra precautions to reduce the risk of errors and protect patients.
High Alert Medications vs. Narrow Therapeutic Index (NTI) Drugs
NTI drugs show a small dose or concentration difference leading to significant therapeutic failures or toxicity.
NTI drugs stand for narrow therapeutic index drugs. These are medications where a small difference in dose or blood concentration can lead to serious therapeutic failures and/or adverse drug reactions that are life-threatening or result in significant disability or incapacity.
Many high alert medications are also NTI drugs, explaining their inherent risk.
A key reason that many high alert medications can cause significant harm or injury if used in error is that they often have a narrow therapeutic index. This means even a small change in dose or blood concentration can lead to very significant undesired effects.
Organizations and Resources for High Alert Medications
ISMP provides lists of high alert medications for different pharmacy settings.
The Institute for Safe Medication Practices (ISMP) is an organization dedicated to preventing medication errors and providing medication safety information. ISMP offers specific high alert medication lists for community/ambulatory care, long-term care (nursing homes), and acute care (hospitals). These lists can be found on their website, ismp.org.
The Joint Commission (JC) accredits healthcare facilities and identifies high-risk medications.
The Joint Commission (JC), also known as JCAHO, accredits and evaluates healthcare facilities for safe and effective patient care. JC standards focus on patient safety and quality, requiring organizations to manage high alert medications. They have also issued a bulletin identifying the medications with the highest risk of injury when misused.
Common High Alert Medication Classes and Their Risks
Insulins and sulfonylureas can cause coma or death due to potent blood sugar lowering effects.
Insulins and sulfonylureas are potent antidiabetic medications. When given incorrectly, their dramatic blood sugar lowering effect can lead to coma and death.
Opioids can cause respiratory depression and death if misused.
Opioid pain medications, when used incorrectly, can cause respiratory depression (stopping breathing), which can lead to death.
Anticoagulants (blood thinners) increase the risk of severe bleeding and death.
Anticoagulants, or blood thinners, pose an increased risk of bleeding. This can have serious adverse effects, even leading to death.
Chemotherapy drugs carry a high risk of toxicity due to their cell-killing nature.
Chemotherapy drugs, used for cancer treatment, have a high risk of toxicity because they kill cells, including healthy ones. Incorrect use can lead to serious adverse effects and death.
Neuromuscular blockers can cause paralysis or death due to muscle-paralyzing effects.
Neuromuscular blocking agents prevent movement. When used in error, they can cause paralysis, permanent injury, and even death.
Injectable concentrated electrolytes (potassium, sodium chloride >0.9%) can cause fatal rhythm changes or brain damage.
Concentrated injectable electrolytes such as potassium chloride and sodium chloride solutions greater than 0.9% (hypertonic saline) are high alert. Injectable potassium concentrates can lead to fatal hyperkalemia and cardiac rhythm changes. Hypertonic sodium chloride solutions can cause brain damage due to severe hypernatremia.
IV beta blockers and antiarrhythmics require caution due to effects on heart rate and rhythm.
Intravenous (IV) beta blockers (like Propranolol) and IV antiarrhythmics are high alert medications that can significantly impact heart rate and rhythm.
Immunosuppressants, intrathecal/epidural meds, and moderate sedatives need careful management.
Other high alert classes include immunosuppressant agents, intrathecal or epidural medications (administered into the spinal cord), pediatric liquid medications requiring measurement, moderate sedating agents (even for children), and anesthetic drugs.
Specific High Alert Medications Identified by The Joint Commission
The Joint Commission highlights insulin, opiates, concentrated potassium, IV anticoagulants, and hypertonic saline.
The Joint Commission identified five high alert medications with the highest risk: insulin, opiates and narcotics (pain medications), injectable potassium concentrates, IV anticoagulants (like Heparin), and sodium chloride solutions above 0.9% (hypertonic solutions).
Concentrated electrolytes pose risks of fatal hyperkalemia or brain damage from hypernatremia.
Injectable potassium concentrates can cause fatal hyperkalemia (high blood potassium), leading to dangerous heart rhythm changes. Sodium chloride solutions above 0.9% can cause severe hypernatremia (high blood sodium), leading to brain damage and death.
Strategies for Reducing High Alert Medication Errors
Educate staff and use visible labels to identify high alert medications.
Strategies to reduce errors include educating healthcare staff about specific high alert medications and using auxiliary labels (e.g., a red 'high alert drug' sticker) to clearly identify these products.
Limit access and implement independent double checks for high alert medications.
Limiting access to certain high alert medications and requiring independent double checks (where two individuals separately verify accuracy of dose, amount, etc.) are crucial precautions.
Utilize technology for automated double checks to ensure medication accuracy.
Technology plays a role through automated double checks, such as computer systems designed to confirm the correct drug, dosage, patient, time, and route of administration before dispensing or administration.
