Focus on High-Alert Medications

High-Alert Medications

While all medications have a level of risk if used incorrectly, a small number of medications bear a heightened risk of significant patient harm when they are used in error. These drugs are commonly referred to as “high-alert” medications. Though mistakes may or may not be more common with these drugs, the consequences of errors with these medications are more devastating to patients.

A 1998 Institute for Safe Medication Practices (ISMP) study revealed that 11% of all serious medication errors involve insulin misadministration, and another 8.9% involved heparin.1 In addition, the summary information from the MedMarxSM 2002 report found that the top seven medications involved in events involving harm (comparable to Harm Score Categories E thru I in PA-PSRS) are high-alert medications including insulin, morphine, heparin, intravenous concentrated potassium chloride, warfarin, hydromorphone, and fentanyl.2 These medications along with meperidine, intravenous chemotherapy, and neuromuscular blocking agents are among those considered high-alert medications.

Among medication error reports submitted to PA-PSRS, approximately one out of four reports involve high-alert medications. Of those reports:

  • 44% involved pain management medications including morphine, hydromorphone (DILAUDID®), meperidine (DEMEROL®) and fentanyl.
  • 14.2% involved heparin.
  • 16.3% involved insulin products.
  • 9.4% involved warfarin (COUMADIN®).

Sixty-five percent of Serious Events involving medications involved high-alert medications. Examples of medication errors involving high alert medications include:

  • A patient receiving an infusion of fentanyl for pain control was ordered a 50 mcg bolus dose, but received 50 mLs.
  • Insulin was administered to the wrong patient based on blood sugar levels of another patient.
  • Two reports concerned patients receiving concentrated epinephrine 1:1,000 undiluted intravenously.
  • An intravenous heparin infusion was programmed to run at 150 mL/hr (the rate for the patient’s antibiotic) rather than the ordered rate of 10 mL/hr.

A list of common high-alert medications is available as a drop down box when entering reports into PA-PSRS at question 23. In addition, a complete list is available from ISMP (www.ismp.org/MSAarticles/highalert.htm) as well as in the PA-PSRS Training Manual and Users’ Guide in Appendix B, page 87.

Additionally, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) includes in their 2004 National Patient Safety Goals that organizations “improve the safety of using high-alert medications” by removing concentrated electrolytes (including, but not limited to, potassium chloride, potassium phosphate, and sodium chloride >0.9%) from patient care units and standardizing and limiting the number of drug concentrations available in the organization.3

Strategies to safeguard the medication use process for high-alert medications may include limiting access to these medications; using auxiliary labels and automated alerts; standardizing the ordering, preparation, and administration of these products; and employing automated or independent double checks when necessary.
