Medication Errors: How QR Scanning Closes the Gap

Medication administration is one of the most important responsibilities in healthcare. A single mistake—such as giving the wrong medication, dose, or administering it at the wrong time—can place an individual’s health and safety at risk.

For organizations supporting individuals with intellectual and developmental disabilities (IDD), medication administration can be especially complex. Individuals may take several medications, receive services in multiple settings, and depend on different staff members to administer and document their medications correctly.

QR-code scanning adds a valuable layer of protection by connecting the individual, medication, current order, and staff member during each medication pass.

Where Medication Errors Occur

Medication errors are not always caused by carelessness. They often occur because the process involves several manual steps. Common errors include:

• Selecting medication intended for another individual
• Administering the wrong medication or dose
• Giving medication at the wrong time or by the wrong route
• Missing a scheduled dose
• Administering a discontinued medication
• Documenting before administration
• Forgetting to document after administration
• Giving a medication twice because documentation was incomplete

The risk may increase during busy medication passes, shift changes, community outings, emergencies, or when unfamiliar staff members are providing support.

How QR Medication Scanning Works

A QR-enabled medication system places a unique code on the medication container, package, label, or blister pack. The individual may also have a unique code connected to their electronic medication administration record, or eMAR.

Before administering a medication, the staff member scans the individual’s code and the medication’s code. The system then compares the information with the current authorized order.

The scan may help verify:

1. 1The right individual
2. 2The right medication
3. 3The right dose
4. 4The right time
5. 5The right route
6. 6The right documentation
7. 7The right reason, when applicable
8. 8The individual’s right to refuse

If the information does not match the order, the system can warn the staff member before the medication is administered.

Closing the Identification and Documentation Gaps

Medication containers can look similar, and two individuals may take the same medication at different strengths or times. Depending only on memory or visual recognition creates unnecessary risk.

QR scanning requires staff to verify both the individual and the medication electronically. If the medication belongs to someone else, has been discontinued, or is not scheduled at that time, the system may display an alert.

Scanning can also document important information automatically, including:

• The medication administered
• The individual who received it
• The scheduled and actual administration times
• The staff member completing the medication pass
• Refusals, omissions, alerts, or other exceptions
• Follow-up actions taken

Real-time documentation reduces the possibility of a medication being administered twice because another staff member did not know it had already been given.

Keeping Up With Medication Changes

Medication orders can change after medical appointments, hospitalizations, or pharmacy reviews. A medication may be increased, decreased, held, or discontinued. When old labels or records remain available, staff may accidentally follow outdated instructions.

A properly maintained QR-enabled eMAR connects each scan to the current authorized order. Scanning an incorrect strength or discontinued medication may generate a warning and prevent staff from completing routine documentation until the discrepancy is resolved.

QR scanning does not replace medication reconciliation, but it can help stop an outdated order from being followed without question.

Improving Accountability Across Settings

Individuals receiving IDD services may take medications at home, at a day program, during respite, or while participating in community activities. Movement between settings can create communication and documentation gaps.

A secure mobile scanning system can help authorized staff access the current medication schedule wherever services are delivered. It can also create a time-stamped audit trail showing what was administered, when it was administered, and who completed the task.

Nurses and supervisors can use this information to:

• Identify missed or late medications
• Monitor refusals and omissions
• Investigate medication errors
• Recognize patterns involving particular shifts or locations
• Provide targeted staff training
• Strengthen quality-improvement activities
• Prepare for regulatory reviews

Technology Does Not Replace Staff Judgment

QR scanning is a safety tool—not a replacement for medication training, nursing oversight, or clinical judgment.

Staff must still compare the medication label with the authorized order, check allergies and precautions, follow special instructions, observe the individual before and after administration, respect the right to refuse, and report concerns promptly.

Staff should never ignore or automatically override an alert. The discrepancy must be investigated and resolved before proceeding unless an authorized emergency protocol directs otherwise.

Organizations must also prepare for unreadable QR codes, power or internet interruptions, device failures, inaccurate data, unauthorized access, and staff workarounds. A written downtime procedure is essential so staff know how to verify, administer, and document medications safely when the system is unavailable.

Making QR Scanning Successful

Successful implementation requires more than installing software. Organizations should:

• Reconcile prescriptions, pharmacy labels, and eMAR orders before activating codes
• Establish clear scanning, alert, exception, and downtime procedures
• Provide competency-based staff training
• Use role-based access and protect confidential information
• Monitor missed scans, late medications, overrides, and refusals
• Use system data to identify trends and improve performance

The Bottom Line

Medication errors often occur in the gaps between the prescription, pharmacy label, medication record, staff member, and individual receiving support. QR scanning helps close those gaps through real-time verification, alerts, and documentation.

When combined with accurate orders, trained staff, nursing oversight, clear policies, and regular monitoring, QR scanning can reduce preventable errors and strengthen accountability.

The goal is not simply to make medication administration faster. The goal is to make every medication pass safer, more accurate, and more person-centered.
