The Core Principle: Using at Least Two Identifiers
Patient identification is a foundational aspect of patient safety, designed to prevent errors by reliably matching the right patient to the right treatment. The most widely adopted and correct method is to use a minimum of two separate, patient-specific identifiers before any intervention, such as administering medication, performing a procedure, or collecting a specimen.
What are acceptable identifiers?
Acceptable identifiers are unique to the individual and directly associated with them. The Joint Commission specifies several acceptable examples:
- Patient's full name: This should be verbally confirmed and spelled out by the patient, if able, to avoid confusion with people who have similar or identical names.
- Date of birth (DOB): Used in conjunction with the name, the DOB is a critical piece of data for distinguishing between patients.
- Medical Record Number (MRN): This is a unique number assigned by the healthcare facility at the time of admission.
- Other person-specific identifiers: This can include a phone number or, in the case of infants, a cord clamp number.
What are unacceptable identifiers?
Conversely, certain methods are explicitly discouraged or prohibited because they are not unique to the individual and can lead to dangerous mix-ups:
- Patient room number or bed location: These can change frequently during a hospital stay and are not tied to a specific person. Relying on this information is a serious safety risk.
- Confirmation questions: Asking confirmation questions like, "Are you John Smith?" is incorrect. A patient may be disoriented or simply agree, even if it is not their information. Staff must instead ask the patient to state and spell their name.
The Step-by-Step Patient Verification Process
Proper identification is an active process that requires the engagement of both the healthcare provider and the patient. It is not a passive check but a critical, deliberate action performed at every point of care.
Verbal confirmation
The most fundamental part of the process is verbal confirmation. Before any intervention, the healthcare professional should:
- Ask the patient to state their full name and date of birth. This is crucial because it requires the patient to provide the information from memory, reducing the chance of an automatic, incorrect confirmation.
- Compare the patient's verbal response to the information on their identification band and medical record. The identifiers must match on all documentation.
Role of the patient wristband
Patient wristbands are a critical tool for providing an immediate source of identification, but they are not the sole identifier. The wristband itself is a source of information, not an identifier. The personal data on the band, such as the name and medical record number, are the identifiers.
- The wristband must be placed on the patient at the time of admission and remain attached throughout their stay.
- For procedures like specimen collection, labels must be applied in the patient's presence after verifying the identifiers to prevent mix-ups.
Technological Enhancements to Patient Identification
Modern healthcare facilities are leveraging technology to increase the accuracy and efficiency of patient identification, reducing the risk of human error.
Barcode scanning and RFID
- Barcode Wristbands: Many hospitals use wristbands with barcodes that can be scanned with a mobile computer. This provides quick, digital access to the patient's electronic health record and helps ensure correct medication and treatment administration.
- RFID Technology: Radio-Frequency Identification (RFID) tags in wristbands or other items allow for automatic reading without a line of sight. These can hold more data than barcodes and offer enhanced data security.
Biometric identification
Emerging technology includes the use of biometrics, which are based on unique physical characteristics. This creates a secure, streamlined check-in process and nearly eliminates the risk of impersonation.
- Fingerprint or facial recognition: These systems can accurately identify a patient during check-in or before a procedure.
- Palm vein or iris scanning: These offer even higher levels of security and accuracy.
Addressing Special Circumstances
Some patient populations require special protocols to ensure accurate identification, as they may be unable to provide verbal confirmation.
- Non-communicative or Unresponsive Patients: In emergencies, a temporary identification may be assigned. However, two identifiers must still be used, such as a temporary 'John Doe' name and a medical record number. Formal identification should be confirmed as soon as possible.
- Same Name Alerts: For patients who share the same or similar names, electronic health record systems can be configured to trigger an alert, prompting staff to exercise extra caution.
Comparing Identification Methods
Feature | Correct Method | Incorrect Method |
---|---|---|
Number of Identifiers | Uses a minimum of two unique identifiers (e.g., name and DOB). | Uses only one identifier, or relies on non-unique information like a room number. |
Verification Process | Asks patient to verbally state their identifiers (name, DOB). | Asks confirmation questions (e.g., "Are you Mr. Smith?"). |
Tool Use | Scans barcode on wristband or uses biometric technology. | Uses wristband as the sole source of information without verbal confirmation. |
Specimen Labeling | Labels specimens in the patient's presence after two-identifier verification. | Pre-labels specimen containers before seeing the patient. |
Conclusion: A Commitment to Vigilance
Ultimately, the correct method for patient identification is a multi-layered approach centered on the consistent use of at least two personal identifiers and the active engagement of the patient. From the initial check-in to every interaction throughout their stay, healthcare providers must remain vigilant. Standardized protocols, staff education, and the adoption of modern technology are all crucial components of a robust system that protects patients from misidentification and ensures they receive the safe, effective care they deserve.
