Barcode scanning is standard practice across retail, logistics, and manufacturing — giving organisations real-time visibility of their stock, rapid response to product issues, and reliable records of what went where and when. Scan4Safety is the NHS’s standardised approach for bringing that same proven capability into patient care.

By creating trusted digital records that link patients to the products, people, places, and processes involved in their care, Scan4Safety enables NHS organisations to make safer clinical decisions, respond rapidly to safety issues such as product recalls, reduce waste, cut costs, and deliver more efficient, higher quality care.

How Scan4Safety works

Scan4Safety uses data carriers (such as barcodes) and data standards (such as GS1 standards) at the point of care to create trusted digital records that link Patients, Products, Places and Processes. This supports NHS organisations to ensure the right care is delivered to the right patient and reduces the risk of misidentification or incorrect treatment.

Scan4Safety also transforms inventory and supply chain management, enabling trusts to track items from supplier to patient, manage stock in real time, respond rapidly to recalls, and capture accurate data for national registries and reporting. By recording the products used, exact location where care is delivered and who was involved, Scan4Safety builds a complete and transparent history of care.

How GS1 standards support Scan4Safety

GS1 standards provide a globally recognised way to create unique identifiers that are carried in barcodes. Each barcode is unique to what it identifies — such as a patient wristband, a medical device, or a clinical location. As GS1 standards are both system and device agnostic, the data captured can be shared seamlessly between systems and organisations to enable interoperability.

In most Scan4Safety use cases, GS1 standards enable:

• Unique identification of people (patients and staff), products (including assets), and places
• Interoperability across NHS systems and suppliers
• Consistent data capture that supports national programmes including the Medical Device Outcomes Registry, the NHS Federated Data Platform, and national clinical registries
• A foundation for meeting NHS data and procurement requirements

Note: there are some exceptions where other data standards may currently be used, for example, blood products.

GS1 is a not for profit organisation. Find out more on the GS1UK website.

The NHS challenges Scan4Safety addresses

Patient safety risks 

Misidentification, medical product mix-ups, medication errors, and manual recording errors cause preventable harm across the NHS. High-profile safety events — including those examined in the Cumberlege Review, Paterson Inquiry, Infected Blood Inquiry, and Poly Implant Prothèse (PIP) breast implants scandal — demonstrate the devastating consequences of poor traceability and delayed recalls. Scan4Safety directly addresses these risks by creating a reliable digital record linking patients to the products and procedures involved in their care. When safety issues arise, affected patients can be identified in minutes rather than days or weeks.

In operating theatres, barcode scanning at the point of care can alert staff in real time to expired products, recalled items, or incorrect product selection — such as a left knee implant selected for a right knee procedure. In medicines management, closed-loop barcode verification can help ensure the right patient receives the right medicine at the right dose. In pathology, scanning patient wristbands at the point of collection significantly reduces “Wrong Blood in Tube” errors, where a sample collected from one patient is labelled with another’s details. For blood transfusions, electronic verification at the bedside provides an automated check that the right blood product is being administered to the right patient.

Rising costs 

Preventable errors and inefficient stock management place a significant and quantifiable burden on NHS budgets. Medication errors contribute to over 36,000 additional inpatient bed days annually at a cost of approximately £17.8 million. Surgical claims — including wrong-site surgery and faulty implants — cost the NHS over £195 million in 2021/22. In 2017/18 alone, 35,931 units of red blood cells were wasted at an estimated cost of £4.6 million, while inefficient inventory management is estimated to contribute to £1 billion in excess shelf stock across the NHS.

The return on investment from Scan4Safety is well evidenced. The six original demonstrator sites achieved recurrent inventory savings of nearly £5 million over two years, with a further £9 million in non-recurrent inventory reductions. NHS Supply Chain’s inventory management programme estimates an average financial benefit of £2.7 million per trust over five years. Beyond direct savings, Scan4Safety supports long-term financial sustainability through reduced waste, more efficient procurement, better stock management, and improved use of clinical time.

Administrative burden 

Manual data entry and paper-based processes place a significant burden on NHS clinical and administrative staff. Recording product details, stock levels, patient care events, and supply chain activity by hand is time-consuming, error-prone, and diverts staff away from direct patient care.

Barcode scanning automates data capture at the point of care, replacing manual recording with accurate, real-time digital records. This reduces transcription errors, eliminates duplicate data entry, and streamlines workflows across clinical and operational teams.

The scale of this benefit is significant. Across six NHS demonstrator sites during the Scan4Safety programme between 2016 and 2018, more than 140,000 hours of clinical time were released back to patient care.

Operational inefficiencies and supply chain visibility

Without real-time visibility of equipment and stock, NHS teams manage resources reactively — staff spend time searching for equipment, stock shortages contribute to delayed treatments, and fragmented tracking of implants, devices, and consumables slows recall response. Scan4Safety provides accurate, up-to-date information on the location and availability of equipment and supplies. When integrated with inventory management systems, this enables proactive stock management, more strategic procurement, and rapid response when safety issues arise.

Data accuracy

Poor data quality is a persistent across NHS settings. Where product and patient information is recorded manually, records are vulnerable to transcription and data entry errors, incomplete entries, and illegible handwriting. This affects the reliability of patient care records, hampers the NHS’s ability to meet national reporting requirements, and limits the value of data fed into programmes such as the Medical Device Outcomes Registry and the NHS Federated Data Platform. Barcode scanning replaces manual data entry with automated, standardised capture at the point of care, creating accurate, complete records that can be trusted across clinical and operational systems.

Scan4Safety across clinical and operational settings

Scan4Safety supports safer, more efficient care across a wide range of NHS settings. Visit the Scan4Safety in Practice section of the website to find real-world examples of how and where barcode scanning is being used across different clinical and operational settings. This includes operating theatres, medicines management, blood tracking, pathology, inventory management and other innovative applications.

Impact by user group

Across all of these settings, Scan4Safety delivers benefits for every part of the NHS:

• For patients — Safer procedures, fewer errors, faster responses to product recalls.
• For clinical staff — Reduced administrative burden, automated alerts that support safer decision-making, and more time for direct patient care.
• For operational and finance teams — Real-time stock visibility, reduced wastage, improved procurement efficiency, and a clear return on investment.
• For NHS leaders — Board-level confidence in safety standards, reliable data for reporting and planning, and alignment with national quality, digital and safety strategies.
