Chapter 1: The Silent Revolution |
How Barcode and RFID Technologies Are Reshaping the Foundation of Modern Healthcare |
Executive Summary |
This chapter introduces the foundational role of automatic identification and data capture (AIDC) technologies---specifically barcodes and Radio Frequency Identification (RFID)---in transforming healthcare delivery. We begin with a fundamental question: why do hospitals, often perceived as temples of cutting-edge technology, still rely so heavily on what appear to be 'simple' scanning technologiesThe answer lies in a paradox of modern medicine: while diagnostic and therapeutic technologies have advanced exponentially, the systems for tracking patients, medications, and equipment have remained surprisingly vulnerable to human error. |
This chapter explores how barcodes and RFID are silently revolutionizing healthcare by addressing three core challenges: patient identification errors, medication administration mistakes, and asset mismanagement. Drawing on real-world examples from both the United States and China, we examine how these technologies have moved from retail applications to become essential patient safety tools. The chapter concludes with a detailed summary that synthesizes key findings and outlines the trajectory for subsequent chapters. |

1.1 The Paradox of Modern Medicine |
Walk into any major hospital in the United States or China, and you will witness a striking contradiction. Alongside million-dollar MRI machines and robotic surgical systems that can perform microsurgery with superhuman precision, you will find nurses and pharmacists manually counting pills, technicians searching for missing infusion pumps, and staff members squinting at handwritten wristbands to confirm patient identities. |
This is not a failure of healthcare innovation. Rather, it reflects a fundamental truth about medicine: the most dangerous moments are not when technology fails, but when humans must perform repetitive, error-prone tasks without technological support. According to a comprehensive review published in the Journal of Information Science and Engineering, hospitals typically lose 10% of their inventory annually, and medical personnel spend between 25% to 33% of their time simply searching for biomedical equipment . This is time stolen from direct patient care. |
The solution to this paradox has emerged not from glamorous fields like genomics or artificial intelligence, but from technologies originally developed for grocery stores and warehouses: barcodes and Radio Frequency Identification (RFID). These automatic identification technologies have found a second life in healthcare, where their ability to answer three simple questions---'Who is this', 'What is this', and 'Where is this'---has proven to be nothing short of transformative. |
|
1.2 The Core Problem: Human Error in High-Stakes Environments |
To understand why barcodes and RFID matter in healthcare, we must first understand the scale of the problem they address. Medical errors are a leading cause of death worldwide. While exact figures vary by country and methodology, the consensus across patient safety research is sobering: a substantial portion of these errors stem from misidentification. |
Consider the 'Five Rights' of medication administration---a foundational principle taught in every nursing school worldwide. Every time a medication is given, five conditions must be met: the Right Patient, Right Drug, Right Dose, Right Route, and Right Time. In a busy hospital ward, a nurse might administer dozens of medications per hour. Each administration requires cross-referencing multiple pieces of information. Each cross-reference is an opportunity for human error. |
The problem extends far beyond medications. Blood transfusions require matching units to patients with absolute precision---a mismatch can be fatal within minutes. Surgical procedures require counting instruments before and after surgery to ensure nothing is left inside a patient. Laboratory specimens must be correctly labeled and tracked from bedside to diagnosis. In each case, the failure mode is the same: a human being made an honest mistake while performing a repetitive, high-volume task. |
Barcodes and RFID address this problem by replacing human memory and manual data entry with machine-readable identification. A scanner does not misread a wristband because it is tired. A computer does not confuse two patients with similar names. These technologies do not eliminate human judgment---they support it by providing reliable, instantaneous data. |
|
1.3 Barcode Technology: The Workhorse of Patient Safety |
How Barcodes Work |
The barcode is a remarkably simple invention with profound implications. A barcode is a machine-readable representation of data---typically a string of numbers---encoded in patterns of parallel lines (one-dimensional, or 1D) or geometric patterns (two-dimensional, or 2D, such as QR codes or Data Matrix codes) . |
When a barcode scanner illuminates the code with light, the dark bars absorb the light while the white spaces reflect it. The scanner converts this reflected pattern into an electrical signal, which is then decoded into the underlying data. This entire process takes a fraction of a second. |
The critical insight behind barcodes is that they function as pointers, not data repositories. The barcode on a patient wristband typically contains only a medical record number---a key that links to a comprehensive electronic health record (EHR) in a central database. This design keeps the barcode simple, reliable, and cheap. A printed barcode costs approximately $0.001---essentially free . |
Two-Dimensional Barcodes in Healthcare |
While traditional 1D barcodes are still widely used, healthcare has increasingly adopted 2D barcodes, particularly the GS1 Data Matrix standard. Unlike 1D codes that can only encode a few dozen characters, 2D barcodes can store up to several thousand characters in a space as small as a postage stamp. |
More importantly, 2D barcodes can encode structured data directly, including the Global Trade Item Number (GTIN), lot number, and expiration date . This means a single scan can capture all the information needed to verify that a medication is authentic, unexpired, and subject to any active recall. |
Fresenius Kabi, a major global healthcare company, has been at the forefront of this transition. The company has introduced Data Matrix barcodes on primary packaging for a substantial portion of its pharmaceutical portfolio. According to the company, these 2D barcodes provide clinicians with a faster, safer way to identify and verify medications, reducing human error and improving traceability . |
The Line-of-Sight Limitation |
However, barcodes have a fundamental limitation: they require a direct line of sight between the scanner and the code. The scanner must be positioned correctly, at the right distance and angle. The code must be clean and undamaged. And crucially, barcodes can only be read one at a time. |
These limitations are acceptable for many applications---a nurse scanning a patient wristband before administering medication is performing a deliberate, one-at-a-time verification. But for applications requiring rapid, bulk scanning---such as inventory management---barcodes become a bottleneck. |
|
1.4 RFID Technology: Beyond Line of Sight |
How RFID Differs from Barcodes |
Radio Frequency Identification represents a fundamentally different approach to automatic identification. An RFID system consists of three components: tags (also called transponders), readers (also called interrogators), and antennas . |
RFID tags contain a microchip that stores data and an antenna that enables communication with the reader. Unlike barcodes, RFID does not require line of sight. A reader can identify tags through cardboard, plastic, and even human tissue, at distances ranging from a few centimeters to over 100 meters, depending on the tag type and reader power. |
Passive vs. Active RFID |
RFID tags fall into two main categories: passive and active. |
Passive RFID tags have no internal power source. They harvest energy from the radio waves emitted by the reader, using that energy to power their microchip and transmit a response. Passive tags are inexpensive---typically $0.10 to $1.50 ---and have an indefinite operational life since they have no battery to deplete. Their read range is limited to approximately 3 to 10 meters (10 to 30 feet), depending on frequency and reader power. |
Active RFID tags contain their own battery, which powers the microchip and enables the tag to initiate communication. Active tags have much longer read ranges---often exceeding 100 meters---and can integrate sensors to monitor temperature, humidity, or motion. However, they are significantly more expensive, typically costing $15 or more, and their batteries must be replaced periodically . |
The Advantages of RFID in Healthcare |
The unique properties of RFID make it exceptionally well-suited to several healthcare applications: |
Bulk reading: A single RFID reader can identify hundreds of tags per second. A pharmacy technician can wave a handheld reader over a shelf and instantly inventory every tagged item, a process that would take hours with barcode scanning. |
Automated monitoring: Active RFID tags can continuously broadcast their presence. Ceiling-mounted readers can track the real-time location of tagged equipment, patients, or staff throughout a facility. |
Tamper detection: RFID tags can be designed to break or change their signal if removed from an object, providing security against theft or tampering. |
Environmental sensing: Active RFID tags with sensors can monitor temperature throughout the cold chain, alerting staff if a vaccine or blood product is exposed to unsafe conditions. |
|
1.5 Barcode vs. RFID: Complementary Technologies |
A common misconception is that RFID will eventually replace barcodes in healthcare. In reality, the two technologies are complementary, each suited to different applications and budget constraints. |
A recent academic review comparing tracking technologies in healthcare concluded that barcode technology exhibits the highest performance for single-tracking medical equipment, while RFID systems are more effective for real-time equipment tracking . The choice between technologies depends strongly on specific organizational goals. |
When to use barcodes: For applications requiring deliberate, one-at-a-time verification---patient identification, medication administration at the bedside, specimen labeling---barcodes are ideal. They are essentially free, universally standardized, and sufficient for the task. |
When to use RFID: For applications requiring bulk scanning, continuous monitoring, or automated location tracking---inventory management, equipment tracking, patient wandering prevention---RFID justifies its higher cost through labor savings and error reduction. |
As one industry expert noted, 'A barcode costs $0.001; an RFID tag costs $0.10. For a simple drug vial, a barcode is fine. For a $50,000 surgical robot part that is easily stolen, RFID pays for itself on the first day of prevented loss.' |
|
1.6 The U.S. Healthcare Context: Market Drivers and Adoption |
Market Size and Growth |
The United States represents the largest market for hospital asset management technologies globally. According to market research, the U.S. hospital asset management market was estimated at $3.2 billion in 2024 . The broader Real-Time Location Systems (RTLS) in healthcare market, which includes RFID-based tracking, was valued at $815.6 million in the U.S. in 2024 and is projected to grow at a compound annual growth rate of 18.9% through 2030 . |
Several factors drive this growth. U.S. hospitals face increasing pressure to optimize resource utilization while managing costs. Rising patient volumes, coupled with the need for rapid response in emergency situations, underscore the importance of having well-managed, readily available equipment and supplies . |
Regulatory Pressures |
The U.S. regulatory environment has been a significant driver of AIDC adoption. The Unique Device Identifier (UDI) system, mandated by the U.S. Food and Drug Administration (FDA), requires that most medical devices bear a unique identifier that can be read by automatic identification technologies. This regulation has forced medical device manufacturers to adopt barcoding and, increasingly, RFID tagging. |
Texas Children's Hospital: A Landmark Case Study |
Perhaps the most compelling U.S. example of RFID-driven transformation comes from Texas Children's Hospital, one of the nation's largest and most comprehensive pediatric healthcare organizations. The hospital manages nearly 4.9 million patient encounters annually . |
Before implementing RFID, the hospital's pharmacy faced a crisis of visibility. An annual inventory review revealed $40 million in medications that could not be properly tracked---representing 8 to 10 percent of their drug budget . Pharmacy technicians spent hours manually counting items and reconciling reports, which often contained discrepancies. Ordering decisions were based on 'gut feeling,' resulting in a toxic combination of overstocking, expired medications, and supply gaps. |
Texas Children's partnered with Zebra Technologies and Tecsys to co-engineer an RFID-powered solution. The key components included desktop RFID printers to create RFID labels for medications valued over $250, hybrid scanners to quickly scan medication barcodes (which then trigger RFID label printing), and mobile computers paired with UHF RFID sleds to instantly locate tagged medications on shelves . |
The results were dramatic. Medication tagging time was reduced from two minutes to just seven seconds per item---a 94% reduction. The pharmacy department achieved 99.99% accuracy in cabinet inventory. In one year alone, the hospital saved $14 million on clotting factor medications by being able to detect expiring medication and prevent loss. The solution provided visibility into the previously untracked $40 million inventory . |
'This one quick scan tells us if we're about to run out of any critical medication,' said Jeffrey Wagner, Vice President of Pharmacy at Texas Children's. 'Before, we only found out after medications expired. Now we can redistribute medications or adjust orders before shortages impact patients' . |
Emergency Medication Safety: A Research Perspective |
The importance of RFID for patient safety extends beyond inventory management. A recent study conducted at a large U.S. academic medical center examined the accuracy of manual restocking for emergency drug boxes---the crash carts used during cardiac and respiratory arrests. |
The study analyzed 451 emergency drug boxes and found that 106 (24%) contained at least one error, resulting in 132 identified errors. The most common errors were expired items (26% of errors), incorrect box expiration dates (22%), and missing items (18%). The medications most frequently involved in errors were lidocaine, mannitol, sodium bicarbonate, and calcium chloride---all critical drugs used in life-threatening emergencies . |
Critically, the researchers determined that implementing RFID technology would detect 96 of these 132 errors (73%). Of the detectable errors, 43 (40%) were ranked as having moderate to severe clinical severity, meaning they could cause patient harm or deterioration during an emergency . |
This study illustrates a key point: manual processes are not just inefficient---they are dangerous. When seconds count during a cardiac arrest, discovering that a necessary medication is expired or missing is not an inconvenience; it is a potential tragedy. RFID offers a path to preventing these errors before they reach the patient. |
|
1.7 The Chinese Healthcare Context: Rapid Modernization |
Market Growth and Government Support |
China represents the world's second-largest market for hospital asset management technologies, and its growth trajectory is remarkable. The Chinese market was estimated at $3.2 billion in 2024 (similar in size to the U.S. market) and is forecast to reach $3.4 billion by 2030, growing at a compound annual rate of 10.8% . |
Several factors distinguish the Chinese market. First, the Chinese government has made healthcare modernization a national priority, with significant investments in hospital infrastructure and digital health technologies. Second, China's large and aging population creates enormous demand for efficient healthcare delivery. Third, Chinese hospitals face many of the same challenges as their U.S. counterparts---inventory waste, equipment loss, and medication errors---but operate within a different regulatory and reimbursement environment. |
The 'Three Streams in One' Model |
Chinese researchers and hospital administrators have developed innovative approaches to integrating barcode and RFID technologies. A particularly notable example comes from a study published in the Chinese Journal of Hospital Management, which described the implementation of a 'three streams in one' integrated management system based on dual-code carriers . |
The system, implemented at a major Chinese hospital, integrates RFID technology with the Unique Device Identifier (UDI) barcode system and the hospital's supply-processing-distribution (SPD) code. The key innovation is the creation of a dual-code carrier---an RFID tag that maps to both the UDI barcode and the SPD code, generating a unique serial number for each medical consumable . |
This integration enables the simultaneous management of three critical 'streams': information flow (patient and medication data), material flow (physical movement of supplies), and financial flow (cost accounting and billing). The system provides full lifecycle traceability for medical consumables, dramatically improving inventory control precision and providing powerful data support for hospital operational decision-making . |
The Track Logistics System at Fudan University Affiliated Zhongshan Hospital |
A practical example of RFID implementation in China comes from Fudan University Affiliated Zhongshan Hospital's Xiamen branch, which installed a track-based logistics system for medication and specimen transport . |
The system uses a network of aluminum tracks (horizontal and vertical) throughout the hospital, along with switching devices and self-powered transport cars. RFID information collection strips are distributed along the tracks, allowing the system to identify and control each transport car, precisely locate its position, and guide it to the designated station . |
The hospital's system includes 72 stations and 64 transport cars (including 16 for contaminated materials and 48 for clean supplies), with 37 stations currently in active use. The system connects multiple departments including the intravenous medication dispensing center, inpatient pharmacy, laboratory, and specimen testing areas . |
Operating data from the system shows remarkable reliability. Over a seven-month period in 2022, the average system failure rate was just 0.237%. During the COVID-19 pandemic, the contactless delivery method reduced the risk of hospital-acquired infections and disease transmission . |
The economic analysis of the system is equally compelling. While the initial construction cost was substantial---approximately 1.48 million yuan per station, with 37 stations totaling about 54.8 million yuan---the long-term economics favor the automated system. After six years of operation, the total cost of the track-based system falls below the cost of manual delivery for the same volume of deliveries. The system handles approximately 198,000 deliveries monthly, compared to 144,000 deliveries annually by manual methods, meaning the automated system is approximately 1.7 times more efficient than manual delivery . |
Supply Chain Integration |
Chinese hospitals have been particularly innovative in integrating barcode and RFID technologies with supply chain management systems. The SPD (supply-processing-distribution) model, which originated in Japan, has been widely adopted in Chinese hospitals and enhanced with RFID technology. |
Under the SPD model, medical consumables are tagged with RFID labels at the point of receipt. These tags are read at each stage of the supply chain---from central storage to ward-level cabinets to the point of patient use. The system automatically tracks inventory levels, generates reorder alerts when supplies run low, and maintains a complete chain-of-custody record for high-value items. |
This integration addresses a major challenge in Chinese hospitals: the management of high-value medical consumables such as cardiac stents, orthopedic implants, and advanced surgical supplies. These items are expensive, must be tracked individually, and have significant implications for patient billing and regulatory compliance. RFID-enabled SPD systems provide the visibility needed to manage these items effectively. |
|
1.8 Comparative Analysis: U.S. vs. China |
While both the United States and China have embraced barcode and RFID technologies in healthcare, their approaches reflect different priorities, constraints, and healthcare system structures. |
Similarities |
Both countries face the same fundamental challenges: medication errors, patient misidentification, equipment loss, and inventory waste. Both have recognized that automatic identification technologies offer cost-effective solutions to these challenges. And both have seen rapid growth in the adoption of these technologies, driven by a combination of patient safety concerns and operational efficiency imperatives. |
Differences in Focus |
U.S. healthcare organizations have tended to focus on patient safety and regulatory compliance as primary drivers for AIDC adoption. The Texas Children's Hospital case study illustrates this: the primary driver was medication safety and the prevention of expired drug administration. The U.S. regulatory environment, particularly the FDA's UDI mandate, has been a powerful force for standardization. |
Chinese healthcare organizations have placed greater emphasis on operational efficiency and supply chain integration. The track logistics system at Zhongshan Hospital exemplifies this focus: the primary driver was reducing labor costs and improving delivery speed. The 'three streams in one' model reflects a systematic approach to integrating AIDC with broader hospital management systems. |
Differences in Scale |
China's hospital system operates at a scale that is difficult to comprehend from a U.S. perspective. A single Chinese tertiary hospital may handle more patient visits annually than an entire U.S. hospital system. This scale creates both challenges and opportunities for AIDC adoption. The challenges include the need for systems that can handle enormous transaction volumes. The opportunities include the ability to realize economies of scale that make large-scale RFID deployments financially viable. |
Regulatory Differences |
The U.S. has a centralized, FDA-driven approach to medical device identification. The UDI system applies uniformly across all devices and is enforced through regulatory oversight. China's approach is more fragmented, with different standards and requirements applied by different regulatory bodies. However, China is increasingly adopting international standards, including the GS1 standards that underpin the UDI system. |
|
1.9 Challenges to Adoption |
Despite compelling benefits, the adoption of barcode and RFID technologies in healthcare faces several significant challenges. |
Cost |
The upfront cost of RFID deployment can be substantial. Readers must be installed throughout the facility. Tags must be purchased and applied to items. Software systems must be integrated with existing EHR and inventory management systems. For a large hospital, a comprehensive RFID deployment can cost millions of dollars. |
The economics of barcode deployment are more favorable. Barcodes cost essentially nothing to print, and barcode scanners are inexpensive. However, barcode-based processes still require investment in software integration and staff training. |
Interoperability |
For AIDC technologies to deliver their full benefits, they must work seamlessly with existing healthcare information systems. This requires adherence to standards---not just for the barcodes and RFID tags themselves, but for the data they encode and the systems that consume that data. |
The GS1 standards, including the GTIN for product identification and the GS1 Data Matrix for 2D barcodes, provide a foundation for interoperability. However, adoption of these standards is not universal, and proprietary systems remain common. |
Clinical Workflow Integration |
Perhaps the most challenging barrier to adoption is integration with clinical workflows. A technology that requires nurses to perform extra steps, carry additional devices, or navigate cumbersome software interfaces will be resisted---often for good reason. Clinical staff are already overburdened; technology should reduce their cognitive load, not increase it. |
Successful implementations treat workflow integration as a primary design requirement, not an afterthought. The Texas Children's Hospital implementation succeeded in part because it reduced the time required for medication tagging from two minutes to seven seconds---a tangible benefit for pharmacy staff. |
Privacy Concerns |
RFID systems that track the location of patients and staff raise legitimate privacy concerns. Who has access to location dataHow long is it retainedCan it be used for purposes other than patient care |
Modern hospital RFID systems address these concerns through several mechanisms. Access controls limit who can view location data. Data anonymization separates identifying information from location histories. And policies restrict the use of location data to approved clinical and operational purposes. |
Technical Limitations |
Each technology has inherent technical limitations. Barcodes require line of sight and can be damaged or obscured. Passive RFID has limited read range and can be affected by interference from metal or liquid (a significant limitation in a hospital environment, where IV fluids and metal equipment are everywhere). Active RFID tags require battery replacement and are expensive. |
The choice of technology requires careful matching to the specific use case. For medication administration at the bedside, barcodes are sufficient and cost-effective. For real-time tracking of infusion pumps throughout a hospital, active RFID may be necessary. |
|
1.10 The Future Trajectory |
The market forecasts suggest continued rapid growth for AIDC technologies in healthcare. The global hospital asset management market is expected to reach $22.1 billion by 2030, growing at 11.5% annually . The RTLS in healthcare market is growing even faster, at 18.9% annually, and is expected to reach $8.8 billion by 2030 . |
Several trends are driving this growth: |
Integration with electronic health records: The distinction between the 'physical' patient (with a wristband and location) and the 'digital' patient (with an EHR) is dissolving. AIDC technologies link the two, enabling care that is both personalized and efficient. |
Artificial intelligence and predictive analytics: The data generated by RFID systems---location histories, usage patterns, inventory levels---is a rich source for machine learning. Predictive algorithms can forecast equipment needs, optimize inventory levels, and identify patterns that precede patient safety events. |
Miniaturization and cost reduction: RFID tags are becoming smaller, cheaper, and more capable. As tag costs continue to fall, applications that were previously cost-prohibitive become feasible. |
Consumerization: Patients are becoming accustomed to automatic identification technologies in their daily lives---contactless payments, keyless entry, smartphone tracking. This familiarity reduces resistance to healthcare applications. |
|
1.11 Detailed Summary |
This chapter has introduced the foundational concepts and real-world applications of barcode and RFID technologies in healthcare, with particular emphasis on the United States and China. |
Key Findings |
1. The scale of the problem is substantial. Healthcare organizations face persistent challenges with patient identification errors, medication administration mistakes, and asset mismanagement. A peer-reviewed study found that hospitals lose 10% of inventory annually and clinical staff spend 25-33% of their time searching for equipment . |
2. Barcodes and RFID address different aspects of the problem. Barcodes are optimal for deliberate, one-at-a-time verification applications such as bedside medication administration. RFID excels at bulk scanning, continuous monitoring, and automated location tracking. The technologies are complementary, not competitive. |
3. U.S. adoption is driven by patient safety and regulatory compliance. The Texas Children's Hospital case study demonstrates the transformative potential of RFID: $14 million in annual savings, 94% reduction in medication tagging time, and 99.99% cabinet inventory accuracy . Emergency medication research shows that 24% of crash carts contain errors, and RFID could detect 73% of those errors . |
4. Chinese adoption emphasizes operational efficiency and supply chain integration. The 'three streams in one' model integrates information, material, and financial flows . The track logistics system at Zhongshan Hospital demonstrates the economic viability of automated transport, with costs falling below manual delivery after six years . |
5. Market growth is accelerating. The U.S. hospital asset management market is estimated at $3.2 billion; China's market is similar in size and growing at 10.8% annually . The global RTLS in healthcare market is projected to reach $8.8 billion by 2030 . |
6. Significant barriers remain. Cost, interoperability, workflow integration, privacy concerns, and technical limitations all pose challenges to adoption. Successful implementations address these barriers through careful planning and a focus on tangible staff benefits. |
|
Implications for Practice |
For healthcare administrators considering AIDC adoption, several principles emerge from the experiences documented in this chapter: |
Start with a clear use case. Identify a specific problem with measurable impact---expired medications in the pharmacy, missing infusion pumps on patient floors, medication errors in a specific unit. Focus the initial deployment on that problem. |
Measure before and after. The Texas Children's case study is compelling because it quantifies the improvement: from 2 minutes to 7 seconds, from 8-10% untracked inventory to 99.99% accuracy. Without measurement, it is impossible to demonstrate return on investment. |
Involve clinical staff in design. The technologies described in this chapter affect the daily work of nurses, pharmacists, and technicians. If these staff members are not involved in system design and testing, the resulting system will fail. |
Plan for integration. AIDC technologies do not exist in isolation. They must integrate with EHRs, inventory management systems, and billing systems. Standards-based solutions---particularly those using GS1 standards---are essential for interoperability. |
Implications for Policy |
For policymakers and regulators, the evidence presented in this chapter suggests several directions: |
Continue to support standardization. The UDI system in the U.S. and the adoption of GS1 standards globally have been essential enablers of AIDC adoption. Continued support for these standards, and for their harmonization across jurisdictions, will accelerate adoption. |
Address privacy concerns proactively. As RFID systems become more capable of tracking patient and staff locations, clear rules for data access, retention, and use are needed. These rules should balance the legitimate needs of healthcare operations with the privacy rights of individuals. |
Support research on implementation. The literature reviewed in this chapter demonstrates that AIDC technologies work when properly implemented. But the 'how' of implementation is at least as important as the 'what.' Research on successful implementation strategies---particularly those that address workflow integration and staff engagement---would be valuable. |
|
Looking Forward |
This chapter has focused on the 'what' and 'why' of barcode and RFID technologies in healthcare. Subsequent chapters will explore specific applications in greater depth: patient identification and the 'wristband of truth'; medication administration systems; surgical instrument tracking; laboratory specimen management; and the integration of these technologies with emerging capabilities like artificial intelligence and the Internet of Medical Things. |
The underlying message of this chapter is simple but profound. In healthcare, where decisions are high-stakes and errors can be fatal, the ability to answer three questions---'Who is this', 'What is this', and 'Where is this'---is not a convenience. It is a safety imperative. Barcodes and RFID, for all their seeming simplicity, provide the answers. |
