4 Medication Safety Checks
A step-by-step guide to reviewing orders, assessing patients, verifying medications and doses, and resolving concerns before administration.
Review the order and assess the patient
Safe medication administration starts before the medication reaches the patient. Review the order, assess whether the medication is appropriate for the patient at that time, and resolve uncertainty before giving it. Medication “rights” are an important check, but they do not replace clinical judgment or safe systems such as barcode scanning.
Review the order and assess the patient
Compare the with the current authorized order. Confirm that the order clearly specifies the medication, dose, route, timing or frequency, and any required parameters. Before administration, clarify an incomplete, unusual, illegible, or apparently unsafe order with the prescriber or pharmacist.
Assess the patient's current condition and relevant history in relation to the medication's purpose and precautions. Depending on the medication, this may involve checking:
Vital signs, such as blood pressure or heart rate before a medication that can lower them.
Relevant laboratory results, such as drug levels, kidney function, glucose, or coagulation results when indicated.
Clinical status and ability to take the medication, including alertness, swallowing ability, nausea, or whether an appropriate feeding-tube route is present.
Dose history and the medication list, including when the last dose was given, whether a dose is due, and whether there may be duplication, an interaction, or a discrepancy in the medication record.
and patient-specific factors. Follow the order and facility policy, and consider allergies, age, weight, pregnancy status, and organ function when relevant.
If an assessment or required test is missing, outside the ordered parameters, or concerning, pause and obtain guidance rather than changing the dose independently.
Verify the patient's identity
Use at least two , such as the patient's full name and date of birth, and compare them with the identification band and MAR. When possible, ask the patient to state the identifiers rather than merely confirm them. A room or bed number is not an identifier.
Use as an added check when available. Do not bypass an alert, and do not treat a successful scan as a substitute for checking the patient and medication.
Check allergies and prior reactions
Review the allergy record and ask the patient about medication allergies before administration. Confirm the suspected substance and, when possible, the reaction, severity, and timing. Distinguish a possible immune-mediated allergy from an adverse effect or intolerance, but do not dismiss an unclear entry or assume that a related medication is safe.
If a listed allergy conflicts with the order, or the patient reports a new reaction, hold the medication and clarify with the prescriber or pharmacist. Document and communicate verified information according to policy.
Verify and calculate the dose
Match the ordered dose to the available medication's name, strength, and concentration. For a calculation, write the units through each step and check that the final result has the correct unit and is measurable.
For example, if the order is and the liquid contains per , the calculation is:
Before giving a calculated dose, verify that it is reasonable for the patient and consistent with the order, applicable dose range or maximum, route, and product concentration. For weight-based dosing, confirm that the weight is current and recorded in kilograms; do not assume a computer calculation is correct if its input may be wrong. For infusions, independently verify the ordered rate, concentration, and pump settings as required by policy. Use an for high-alert medications when required by facility policy; this does not replace each clinician's own check.
Use a for doses below one, such as , and avoid a trailing zero: write , not . These practices reduce the chance of misreading a dose.
Check the medication and label
At each relevant handling stage, compare the medication label with the MAR and order. Common checkpoints are before removing the medication from storage, before preparing it, and before returning or discarding the container. Confirm the medication, strength or concentration, dosage form, route, and expiration date. Inspect for damage, contamination, unexpected appearance, or improper storage. Do not use a product that is expired, compromised, or not clearly identifiable.
If medication is transferred from its original packaging, label the new container promptly. In procedural settings, Joint Commission requirements specify labeling medications and solutions that are not administered immediately, including when transferred to another container. Follow applicable facility requirements for label contents, which may include the medication name, strength or concentration, amount, diluent and volume, and preparation or expiration information.
Never leave an unlabeled syringe, cup, or solution for later identification. If its contents cannot be confirmed, discard it according to policy.
Pause before administration
At the bedside, make a final comparison of the patient, MAR, and prepared medication. Confirm that the medication is due and that no new assessment finding, allergy information, order change, or patient refusal has altered the plan. Explain the medication and invite questions. Perform hand hygiene and use the correct technique for the medication and route.
If anything does not match, or you cannot explain why the dose is appropriate, stop, secure the medication, and resolve the discrepancy before proceeding. The overall safety sequence is to review and clarify the order; assess the patient and required parameters; verify identity with two identifiers; check allergies and reactions; calculate and evaluate the dose; inspect the product and expiration; label transferred medications promptly; and complete a final bedside comparison. Technology and checklists support safety, but unresolved doubts require a pause and clarification.
