What is Patient Identification?
Patient identification is the process of ascertaining the identity of a patient through reliable means. It is the process of linking a patient to the correct information, treatment, and services. Before providing healthcare services, the identity of the patient has to be ascertained. In order to verify identity in healthcare, at least two methods are to be used.
The methods can include a patient’s name and date of birth, or a patient’s unique medical record number. A patient’s room number is not to be used for identification. Patient identification happens at all stages of service delivery from registration, consultation, diagnostics, treatment, and surgery. It happens during discharge from a hospital.
To illustrate, before medication administration, a nurse will match the patient’s name and date of birth on the medication administration record to the patient’s ID wristband. An efficient patient identification process reduces perplexity, repetition of medical records, and improves communication among the members of the healthcare team.
Importance of Patient Identification
The function of patient identification is to guarantee the quality of the healthcare provided and protect the patient from preventable medical errors.
Medical Errors
An identification process helps decrease the chances of medical mistakes. Improper identification exposes the patient to the risk of receiving an inappropriate medication, treatment or diagnostic procedures.Prior to the implementation of any clinical activity, healthcare professionals should check the patient’s ID to verify the patient identity.
Patient Safety
The patient’s safety and health is ensured through proper identification and verification of information throughout the patient’s stay in the health facility. Standard identification methods create and guarantee a safe clinical environment.
Accurate Medical Records
Medical records should be accurate to include the patient’s diagnosis, history of allergies and adverse reactions to medications, treatment, and test results. Accurate identification reduces the chance of duplication of medical records and mismatch of a patient’s healthcare history.
Improves Healthcare System Efficiency
The function of patient identification is to provide healthcare professionals with the ability to retrieve correct patient information confidently and in a timely manner. Implementing Patient Management Software helps healthcare facilities organize patient records, streamline registration, manage patient information, and improve coordination among different departments. Together, accurate patient identification and digital patient management improve healthcare efficiency and reduce administrative errors.
Patient Confidence in the Healthcare System
Patients expect the healthcare system to accurately maintain patient records and deliver the treatment the patient is entitled to receive. Verifying a patient’s identity helps ensure patient safety, shows professionalism and builds confidence in healthcare services.
Role of Patient Identification in Healthcare and Compliance
Patient identification impacts healthcare operations, quality management, regulatory compliance and the protection of patient information.
Supporting Healthcare Safety Standards
Accurate identification of patients is embedded in the essential safety practices and standards of healthcare accreditation organizations and patient safety frameworks.
For instance, requirements relating to patient identification can be found in the essential standards for healthcare quality established by The Joint Commission.
The best way to achieve this is to implement training, standardized processes, and oversight of the identifiers used by staff.
Maintaining Regulatory Compliance
Healthcare organizations are required to conform to regulatory standards that impact patient data, including the accuracy and security of medical records and patient information. Ma intaining Digital Medical Records helps healthcare facilities organize patient information, maintain accurate documentation, and support compliance with applicable healthcare standards.
The Health Insurance Portability and Accountability Act (HIPAA) protects the health information of patients and sets standards for the confidentiality and security of medical data and records.
While HIPAA does not stipulate an approach to patient identification, organizations can benefit from verifying the identity of individuals to access records and reduce inappropriate disclosure of information.
Healthcare organizations can meet the varying specific requirements of regulatory compliance in their jurisdiction through documentation and effective clinical management.
Impact of Technology on Patient Identification
Various technologies have enhanced patient identification by reducing dependence on manual verification and improved management of healthcare information.
The healthcare industry has many challenges and opportunities in the area of patient identification. Traditionally, much of the patient identification process has relied on handwriting, or oral confirmation.
Thus, in an effort to improve the identification and reduction of duplication of patient records, electronic records systems can assist staff in identifying duplicate patient records prior to electronic registry.
Improving Clinical Communication
Correct patient identification gives the healthcare team confidence when exchanging patient information. This is essential when patient care is delivered across multiple units and/or facilities.
Supporting Healthcare Accountability
There is an increasing expectation from professional regulatory bodies, healthcare facilities and accrediting agencies that healthcare organizations implement systems to accurately identify patients and maintain accurate documentation of decisions made and actions undertaken by healthcare staff in the course of their work.
These records facilitate clinical audits, investigations of adverse incidents, quality improvement activities and support the organization’s overall accountability.

How Does Technology Help Identify Patients?
To improve the accuracy, speed and security of patient identification systems, various technologies have been adopted by healthcare organizations.
Barcode Identification Systems
The use of bar code technology in patient identification has fostered improved systems for the administration of medication and collection of patient specimens in the healthcare facility.
Patient identification wristbands contain unique barcodes. Staff scan these barcodes before administering medication to confirm the patient’s identity. Barcode systems reduce manual data entry and help ensure that the correct treatment is given to the right patient.
Biometric Identification Technology
The use of physical attributes such as facial features or fingerprints help verify a person’s identity. This is also known as biometric identification.
Biometric technology can play a role when patient identification is not available, or when a surrogate verification system is needed by a healthcare organization.
There are many considerations for the use of biometric technology including privacy, consent, data protection, accuracy and accessibility.
Electronic Health Records (EHRs)
Electronic Health Records (EHRs) are digital records of a person’s health and medical history. These include patient demographics, health status, medical history, diagnoses, medications and orders, treatments, and/or tests.
Electronic Health Records can be identified and linked to the correct patient through the use of unique patient identifiers.
When integrated and implemented correctly, EHR systems improve healthcare and help provide information in a more timely and efficient manner. This helps facilitate care and improve the overall health of a patient.
RFID Technology
RFID technology utilizes radio waves to automatically identify and track tags that are attached to objects. This can be a replacement to barcode technology to identify patient or treatment wristbands. Unlike barcode technology, some RFID systems do not need a direct line of sight for scanning.
While this technology can be utilized for patient identification and treatment verification, great care must be taken to ensure unauthorized access is avoided.
Master Patient Index (MPI) Systems
A Master Patient Index (MPI) is a database that helps eliminate multiple identifiers for a single patient across various healthcare information systems. The MPI connects patient records using demographics data and/or identifiers.
Advanced EMPI solutions can identify potential duplicate records and assist in merging health information across multiple records and healthcare organizations.
Artificial Intelligence and Patient Matching
Artificial intelligence (AI) and machine learning (ML) can be used with demographic information to pinpoint patient records that may be mismatched or duplicated, thereby assisting with patient identification.
Improving patient matching within large, complex healthcare systems is where the application of AI and ML would be most beneficial.
The use of automation to make matching decisions carries a risk of incorrect identification and should be guided by appropriate oversight and/or checks.
Conclusion
Patient identification is integral to the delivery of safe, high-quality, and efficient health care services. It serves to eliminate preventable risks and errors, fosters clinical communication and compliance, and protects patient safety and information.
There is a growing adoption of automated technologies such as bar coding, biometrics, electronic health records, AI in patient matching and RFID, to address patient identification challenges within healthcare.
However, investing in technology alone will not ensure accurate patient identification. This requires the implementation of organization-specific practices along with the appropriate training and ongoing oversight of employees.
Healthcare facilities should be committed to ensuring accurate patient identification. This serves to reduce preventable risks, improve the overall quality, efficiency and safety of the services offered.
