Hospitals are increasingly under pressure because of the growing volume of imaging tests carried out, but also because of the sophistication of the attacks by the cybercriminal. Conventional security systems are unable to meet today's challenges to patient records and radiological data. In this research, these challenges are addressed directly by designing an advanced defence system that is specifically designed for medical imaging archiving and communication systems in radiology departments. Architected an extensive protective architecture with seven layers that are interconnected. It's a combination of cutting-edge encryption techniques capable of resisting the powerful future quantum computer, authentication processes that validate every access attempt on the fly, data patterns that are learned, suspicious activity recognized, blockchain technology that makes data impossible to tamper with, and predictive algorithms that foresee threats before they happen. Our system is proactive, identifying and neutralising threats at an early stage, instead of reacting to attacks as they happen. Real-world validation took place within five different hospital networks, covering two years, and thus subjected the framework to the real conditions of operation and to real cyber threats. The results of the system's performance were outstanding – the system had a rate of 99.9% accuracy in detecting malicious activities and a rate of 0.15% False Alarms. The overhead for security operations was just 23 milliseconds, not affecting clinical workflow. Most impressively, there was a 67% reduction in the number of attempts to break in onto the network unauthorisedly, due to the formidable defence measures that they faced.Our framework thwarted 847 real tests against it, ranging from sophisticated persistent intrusions and previously unknown software vulnerabilities to attempts by ransomware to encrypt patient information – all during testing. The system ensured complete compliance with healthcare privacy laws from various jurisdictions, aligning with the American HIPAA regulations, the European GDPR and the new quantum-security protocols. In essence, this is a paradigm shift in medical imaging security, offering healthcare institutions proactive and intelligent protection that safeguards patient privacy and institutional integrity in the face of future threats.
Since announcing the implementation of a single electronic health record for all South Africans, the government has not yet informed healthcare facilities of how this would be accomplished. The siloed South African healthcare system would have to be redesigned to accommodate a single electronic health record. A systematic literature review conducted across three databases returned 9 790 results. By applying ten filters, 22 documents were eventually retrieved for analysis. The analysis showed that existing research focuses on healthcare architectures from a theoretical perspective. Therefore, the literature review revealed a practically based research deficiency and a lack of theoretical studies merged with practical cases. Seeking to enhance the understanding of designing a single electronic health record, the documents were analysed using a qualitative inductive content analysis technique, revealing that a single electronic health record cannot be formulated using a fully centralised architecture as this is not practical. A fully decentralised architecture, such as blockchain, is equally infeasible because this requires significant changes to the existing systems and infrastructure and would require re-skilling system builders. Since the South African healthcare architecture is already decentralised, hybrid architecture incorporating edge computing with clusters of systems and information that connect using middleware should be considered.
As autonomous AI agents gain the capacity to execute consequential actions in high-stakes domains -- medical prescribing, financial transactions, critical infrastructure control -- existing authorization mechanisms fail to answer a fundamental question: was the authorizing human genuinely conscious, uncoerced, and cognitively capable at the exact moment of authorization? Passwords, static biometrics, and digital signatures verify identity, not intent state. We present LICET (Latin: it is permitted), a middleware protocol that cryptographically binds AI agent authorization events to the real-time physiological state of the authorizing human via a three-layer architecture: (1) an identity anchor using ECG waveform morphology -- an anatomically determined signal resistant to pharmacological manipulation; (2) a liveness layer using continuous electrodermal activity (EDA) and overnight HRV pattern matching; and (3) a voluntary state layer using personalized Mahalanobis distance fusion across five physiological channels with pharmacological attack pattern detection. LICET additionally provides: per-event session-key derivation via HKDF; a Schnorr zero-knowledge proof over BN128, enabling third-party audit without exposing biometric data; a SHA-256 hash-chained ledger providing tamper-evident authorization records; and a four-level biometric trust hierarchy (L0-L3) aligned with IETF RATS architecture (RFC 9334). The protocol is designed as a coercion cost elevation mechanism: no single pharmacological intervention at survivable doses defeats the multi-signal fusion system. A reference implementation is publicly deployed at https://licet.dev.
Background: Healthcare organizations face unprecedented challenges in maintaining process compliance due to increasingly federated data and systems topologies, coupled with complex state, federal, and jurisdictional regulatory compliance and verification requirements. The emergence of distributed ledger technology (DLT) and artificial intelligence presents both transformative opportunities and significant compliance challenges. These emerging technologies enable computing paradigms that shift toward data locality models where computational models meet the data rather than moving sensitive patient information across organizational boundaries. This computational approach offers innovative pathways to mitigate data breach risks, while simultaneously introducing new verification complexities as the underlying technologies continue to advance: healthcare entities must cryptographically prove that operations performed on locally-held data were executed according to approved specifications while enabling selective disclosure capabilities across entity lines. However, traditional verification mechanisms lack the cryptographic guarantees necessary for these privacy-preserving, multi-entity healthcare workflows, creating substantial risks in clinical decision-making, patient privacy, and regulatory adherence. Objective: This paper introduces the ZK-PRET Business Process Prover framework that integrates Object Management Group (OMG) business process standards with zero-knowledge cryptographic verification to enable privacy-preserving healthcare process compliance across distributed systems. Methods: We developed a multi-layer architecture combining formal business process modeling, zero-knowledge proof generation, and regulatory compliance verification. The framework extends established OMG standards with cryptographic verification capabilities to achieve verifiable compliance, privacy preservation, and regulatory accountability. Implementation testing was conducted in synthetic data environments designed to represent real-world healthcare scenarios.¹ These environments enable comprehensive modeling and testing of multi-entity process orchestration patterns while maintaining privacy protections essential for healthcare research and development. All scenarios, clinical examples, and process expressions presented in this paper utilize synthetic data to ensure no real patient data, clinical records, or identifiable health information was used. Results: The ZK-PRET Business Process Prover framework demonstrates practical applicability across many healthcare domains including treatment planning, telemedicine coordination, healthcare administration, consumer health services, multi-entity clinical trials, and supply chain management. Implementation results demonstrate cryptographic verification capabilities that enable mathematical prevention of regulatory violations rather than post-hoc detection. The results demonstrate configurable privacy preservation through zero-knowledge verification and consistent proof sizes suitable for modeling complex orchestrations, while leveraging already widely used Web 2 process models, suitable for multiple runtime deployment topologies. Conclusions: Zero-knowledge healthcare process verification represents a foundational technology for regulatory compliance in distributed healthcare systems. While agentic AI systems present important opportunities for automation, the underlying requirement for verifiable process compliance through cryptographic means brings broader challenges. ZK-PRET Business Process Prover addresses these challenges in healthcare transformative flows, enabling safer deployment of autonomous systems while maintaining regulatory standards.
Autonomous AI agents executing consequential actions require authorization mechanisms that verify not only identity but voluntary intent. LICET (Latin: it is permitted) is a cryptographic middleware protocol binding AI agent authorization to real-time multi-modal physiological state via a three-layer architecture: (1) ECG waveform morphology matching as a medication-resistant identity and liveness anchor; (2) electrodermal activity (EDA) as a sympathetic cholinergic liveness signal immune to beta-adrenergic blockade; and (3) personalized Mahalanobis distance fusion over five physiological signals to elevate the cost of pharmacological coercion attacks. LICET defines a Biometric Trust Level hierarchy (L0-L3) aligned with the IETF RATS architecture (RFC 9334), per-event HKDF session-key derivation, HMAC biometric temporal signatures, Schnorr zero-knowledge proofs over BN128, and a SHA-256 hash-chained tamper-evident ledger. A reference implementation is publicly deployed at https://licet.dev/v1/.

Background Health information systems (HIS) are critical for digital health transformation, yet fragmentation and poor interoperability adoption remains a major challenge. Objectives This study systematically reviews architectural patterns used in HIS and evaluates their alignment with ecosystem-level requirements. Methods Following PRISMA 2020 guidelines, a systematic literature review was conducted across Scopus, IEEE Xplore, PubMed, and Web of Science (2020–2025). Eligible studies described, evaluated, or proposed HIS solutions. Results From an initial set of 304 records, 89 met the inclusion criteria. Service-based and decentralized/distributed ledger architectures were predominant, with emerging models integrating edge computing and modular design. FHIR-based contracts are found as stabilizers of interfaces, enabling validation and reducing integration costs. However, gaps persist in cross-border care, sustainability, and artificial intelligence integration. Conclusion While microservices dominate current HIS architectures, achieving resilient, interoperable ecosystems requires greater architectural diversity and intersectoral collaboration.
Background The medical device sector, valued at $569 billion, faces persistent financing challenges. Around 78% of startups fail because of capital shortages, not due to lacking technical quality. Blockchain-based tokenization emerges as a way to broaden access, yet success relies on economic factors of platforms and clear regulations. Methods Transaction cost data from Bitcoin, Ethereum, and XRP Ledger covered 540 days from January 2024 to June 2025, providing 3,240 observations per network. Experts, numbering 12, participated in a modified Delphi method to form a framework tailored to healthcare. Project outcomes came from Monte Carlo simulations running 10,000 iterations, checked by a triple control-loop system, and compared against two real-world examples. Volumes of transactions drew from stochastic models involving monthly, quarterly, and annual elements, mixing fixed regulatory needs with variable market influences. Results Layer-1 (L1) fees differ by orders of magnitude; representative 2025 snapshots show BTC and ETH L1 far above XRPL and major ETH L2s. XRPL fees are typically a tiny fraction of a cent; the base cost is 10 drops (0.00001 XRP) and is dynamically adjusted by network load. Probabilities of success varied from 10.1% to 12.3% on Bitcoin, 31.4%–48.3% on Ethereum based on Layer-2 adoption, and 71.6%–73.2% on XRP Ledger. Investor involvement correlated negatively with logarithms of costs, showing Spearman <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="m1"><mml:mrow><mml:mi>ρ</mml:mi></mml:mrow></mml:math> of −0.91. Differences in success exceeded 60 percentage points across platforms. Examples illustrated how elevated expenses reduce engagement in VitaDAO on Ethereum, whereas low-cost systems like XRP Healthcare support ongoing involvement. Conclusion Choosing a blockchain platform critically influences viability in tokenizing medical devices. Layer-2 options reduce cost gaps but add complexities in bridging and use. Platforms offering stability, minimal fees, and regulatory alignment promote wider inclusion and reliable funding. Technical features, steady costs, and readiness for compliance together shape whether tokenization boosts innovation in healthcare or maintains barriers.

Decentralized applications (DApps) have gained prominence with the advent of blockchain technology, particularly Ethereum, providing trust, transparency, and traceability. However, challenges such as rising transaction costs and block confirmation delays hinder their widespread adoption. In this paper, we present our DApp named W2E - Workout to Earn, a mobile DApp incentivizing exercise through tokens and NFT awards. This application leverages the well-known ERC-20 and ERC-721 token standards of Ethereum. Additionally, we deploy W2E into various Ethereum-based networks, including Ethereum testnets, Layer 2 networks, and private networks, to survey gas efficiency and execution time. Our findings highlight the importance of network selection for DApp deployment, offering insights for developers and businesses seeking efficient blockchain solutions. This is because our experimental results are not only specific for W2E but also for other ERC-20 and ERC-721-based DApps.
Ethereum has recently switched to a Proof of Stake consensus protocol called Gasper. We analyze Gasper using PRISM+ , an extension of the probabilistic model checker PRISM with primitives for modeling blockchain data types . PRISM+ is therefore used to rapidly and automatically analyze the robustness of Gasper when tuning, up or down, several basic parameters of the protocol, such as network latencies and number of validators. We also study the effectiveness of Gasper in updating stakes and its resilience to three attacks: the balance, bouncing and time attacks.

Abstract Objective The purpose of this study was to conduct a scoping review of publications that explored blockchain technology in the context of interoperability and challenges of electronic health record (EHR) implementations. We synthesize the literature regarding standards and security, specifically regulation, regulatory operability, and conformance to standards. We review open practitioner questions that were not addressed in the studies as directions for further research. Materials and Methods We conducted a literature search in the OVID databases (Medline and Embase) on terms blockchain, implementation, interoperability, EHRs, security, and standards. The search resulted in 152 nonduplicate, peer-reviewed manuscripts, of which 15 were relevant to our objective and included for synthesis. Results Based on the search results, we analyzed the adoption of blockchain technology in the healthcare systems and challenges to EHR implementation of blockchain. From the synthesized research, we categorized and reported compelling factors of blockchain for EHR integration using current knowledge on blockchain research standardization and architectural challenges. Discussion Our research showed promise in implementing blockchain technology associated with EHRs, especially with Health Information Exchanges. The studies relevant for both EHR (n = 5) and blockchain (n = 10) reported compelling factors and limitations of the architecture. Security (n = 4) and interoperability (n = 4) features were reported as compelling requirements with lingering challenges. Standardization literature (n = 3) reported implementation challenges. Conclusion This study shows promise in implementing blockchain technology within EHR systems. The adoption is increasing; however, multiple implementation challenges remain from architectural perspectives (eg, scalability and performance), to security challenges (eg, legal requirements), and standard perspectives including patient-matching problems.

Modern healthcare management and clinical practice strongly rely on data and scientific evidence. Digital technologies, tools, and services are core components of Healthcare Management and scientific Research (HMR). Data interoperability, security, privacy, and ease of sharing represent fundamental conditions for guaranteeing quality HMR. Current data management solutions in HMR are mainly built on two technological infrastructures: cloud-based (CB) or distributed ledger systems (DLTs). DLTs offer alternative and reliable alternatives for the management and sharing of data in HMR. Their use can help increase confidence and trust in the integrity of data and the resulting evidence. \nThe aim of this paper is to shed light on CB and DLT solutions, emphasizing the potential role of innovative digital solutions based on DLTs in creating a data-driven transformation of HMR, and to describe relevant examples and practical uses of DLT-based solutions for patients, healthcare management, and research activities. \nDLTs in particular can be increasingly useful for patients to truly have control over their health, for healthcare policymakers to increase the quality of organizational processes, and for research funders, editors and publishers to increase the return on investment, and the reuse and reproducibility of research. \nIn conclusion, harnessing the potential of digital technologies is essential to transform healthcare management and research, by enhancing data quality, reliability, and trust.

Electronic Health Records Systems
Artificial Intelligence in Healthcare and Education
Adopting and implementing the Clinical Decision Support System (CDSS) technology is a critical element in an effort to improve national quality initiatives and evidence-based practice at the point of care. CDSS is envisioned to be a potential solution to many current challenges in the healthcare sphere, which includes information overload, practice improvement, eliminating treatment errors, and reducing medical consultation costs. However, the CDSS did not manage to achieve these goals to the desired levels and provide context-appropriate alerts, although integrated with the electronic health records (EHRs) (1). Clinical decision support alerts can save lives, but frequent ones can cause increased cognitive burden to clinicians, worsen alert fatigue, and increase the duplication of tests. This ultimately increases health care costs without refining patient outcomes. Studies show that 49-96% of clinical alerts are ignored, raising questions about the effectiveness of CDSS (1). Blockchain, a decentralized, distributed digital ledger that contains a plethora of continuously updated, time-stamped, and highly encrypted virtual record, can be a key to addressing these challenges (2). The blockchain technology if integrated with the CDSS can serve as a potential solution to eliminating current drawbacks with CDSS (3). This article addresses the most significant and chronic problems facing the successful implementation of CDSS and how leveraging the Hyperledger Fabric can alleviate the clinical alert fatigue and reduce physician's burnout using patient-specific information. The proposed architecture framework for this study is designed to equip the CDSS with overall patient information at the point of care. This then empowers the physicians with the blockchain-integrated CDSS, which holds the potential to reduce clinician's cognitive burden, medical errors, and costs and ultimately enhance patient outcomes. The research study broadly discusses how the blockchain technology can be a potential solution, reasons for selecting the Hyperledger Fabric, and elaborates on how the Hyperledger Fabric can be leveraged to enhance the efficacy of CDSS.
BACKGROUND: Clinical decision support (CDS) is a tool that helps clinicians in decision making by generating clinical alerts to supplement their previous knowledge and experience. However, CDS generates a high volume of irrelevant alerts, resulting in alert fatigue among clinicians. Alert fatigue is the mental state of alerts consuming too much time and mental energy, which often results in relevant alerts being overridden unjustifiably, along with clinically irrelevant ones. Consequently, clinicians become less responsive to important alerts, which opens the door to medication errors. OBJECTIVE: This study aims to explore how a blockchain-based solution can reduce alert fatigue through collaborative alert sharing in the health sector, thus improving overall health care quality for both patients and clinicians. METHODS: We have designed a 4-step approach to answer this research question. First, we identified five potential challenges based on the published literature through a scoping review. Second, a framework is designed to reduce alert fatigue by addressing the identified challenges with different digital components. Third, an evaluation is made by comparing MedAlert with other proposed solutions. Finally, the limitations and future work are also discussed. RESULTS: Of the 341 academic papers collected, 8 were selected and analyzed. MedAlert securely distributes low-level (nonlife-threatening) clinical alerts to patients, enabling a collaborative clinical decision. Among the solutions in our framework, Hyperledger (private permissioned blockchain) and BankID (federated digital identity management) have been selected to overcome challenges such as data integrity, user identity, and privacy issues. CONCLUSIONS: MedAlert can reduce alert fatigue by attracting the attention of patients and clinicians, instead of solely reducing the total number of alerts. MedAlert offers other advantages, such as ensuring a higher degree of patient privacy and faster transaction times compared with other frameworks. This framework may not be suitable for elderly patients who are not technology savvy or in-patients. Future work in validating this framework based on real health care scenarios is needed to provide the performance evaluations of MedAlert and thus gain support for the better development of this idea.
The Internet of Things is a novel paradigm which involves the increasing prevalence of objects and entities supported with identifiers and the ability to exchange the data over a network. However, with all these advantages the risk comes, as the huge number of connected devices gives hackers more entry points. Distributed Ledger Technology (DLT) can stave off security threats to Internet enabled devices by providing a distributed ledger for their functioning, thereby eliminating the central node that networks usually depend on for management by their users. Internet of Things and Application (IOTA) is a new technology designed specifically for the Internet of Things (IoT) industry which depends on the distributed ledger for storing transactions. The main contribution of this thesis is to study and run a set of test cases in healthcare industry to prove the effectiveness and viability of using IOTA in many healthcare applications using data, images or even videos. We will also do a comparative analysis with Blockchain to prove that IOTA technology could stand all odds in terms of feasibility, reliability and robust data security.

The United States Veterans Administration provides a medical care delivery system comprising more than 170 hospitals, clinics and domicilliaries. Historically, these institutions have been relatively autonomous in their day-to-day operations and consequently efforts at computerization have been difficult to adequately coordinate. A recent undertaking of the VA has been to establish decentralized coordination of planning and implementation for hospital computer systems. This presents a unique opportunity to promote standard, portable and well-designed solutions to meet the widely variable needs of a large and diverse health care delivery organization. Although computer systems for each hospital will vary with the needs of the hospital, functional program packages can be delivered and maintained in a cost-effective and manpower-efficient manner. Additionally, because all systems will be based on a common data dictionary it will be possible to gracefully expand systems as needed and to study clinical care and delivery methodologies across many institutions.
Reduced reimbursements from the federal government and third-party payors have threatened the financial viability of many hospitals. An increasing number of hospitals are losing money from their primary mission of caring for patients. The hospital “industry” is still viewed by many as inefficient. Hospitals are generally not run like businesses, nor is it really possible for them to function in the same manner because they have to provide services, to some extent unpredictable, 24 h a day, 7 days a week. Unlike businesses, they cannot increase the charges to their clients to any significant extent when their costs increase because fees are largely dictated by the federal government. For no other business is there the equivalent of capitation or dictation of prices by outside organizations as there is in the medical business. It is perhaps easier for hospital administrations to assess the productivity of their clinical laboratories than of most other hospital services. The number of tests, the number of staff, and the cost of running the service as determined by the supply and salary budgets can be readily quantified. Furthermore, these factors can be bench-marked against the performance of other institutions. However, clinical laboratories also have to contend with the absurd concept of the “billed test” beloved by the federal government, insurance carriers, and consulting companies lacking laboratory expertise. The “billed” test assigns equal weight to a multitest outpatient panel as it does to a dipstick urinalysis or to an elaborate genetic test that is labor-intensive and may take days to complete. This ridiculous concept makes comparisons of productivity between institutions impossible. Indeed, the billed test concept hides increases in productivity because one billed outpatient test may generate as much work as 12 inpatient tests. Successful efforts by hospitals to reduce their inpatient testing, because of non-reimbursability, then mask any increase in revenue-generating outpatient tests. This dual objective of reducing unnecessary inpatient testing and capitalizing on the potential for outpatient revenue has become a major charge for the responsible clinical laboratory director. Clinical laboratories everywhere have been faced with the challenge of doing more tests at less cost, i.e., boosting their productivity. Many laboratories have reached the point at which it is impossible to increase productivity using the equipment that they have. Although each generation of “automated” analyzers usually provides some improvement in throughput and turnaround time for results, they do not have the ability to make the quantum improvements that are a prerequisite to significantly improving productivity. This has led to the concept of “total laboratory automation”, as much a misnomer as “automation” is for a single laboratory instrument. Total laboratory automation goes beyond the automation of analyses but includes automation of much of the important hitherto labor-intensive manual preanalytical phase in the process. The concept was conceived in Japan and has been widely accepted there, so that many large Japanese hospitals now include robotized specimen processing and delivery systems. In the United States, only a very small proportion of even the largest hospital and reference laboratories have installed such systems. Clearly, many laboratory directors have been waiting to learn of the success, or otherwise, of the automated systems in daily operation before they, too, embark on such a major investment. Many also remain uncertain as to whether maximum centralization, as represented by total laboratory automation, is to be preferred over maximum decentralization, as represented by point-of-care testing. The 1999 Clinical Chemistry Forum was designed to present the arguments as to why a fresh approach to laboratory testing was needed and to detail the steps necessary to make the decision whether to commit to total laboratory automation and how to identify the steps involved in a successful installation. The presentations began, appropriately, with discussions of alternative approaches to coping with rapidly escalating workloads. These included total laboratory automation for both individual hospitals and for networks of hospitals. Within the laboratory, alternative approaches were presented, including the use of modular components and automation of selected fixed tasks. The topics covered included a discussion of the components of the necessary overall planning process by a senior administrator from an integrated health system. Another paper dealt with the internal marketing of the concept by the laboratory to the administration and medical staff who would have a major, and vested, interest in the successful operation of a new system. Two of the critical areas that can make or break a robotic system are the layout of the facility with its attendant demands, which involves providing an appropriate environment for both the operators and the analytical systems, and the design and implementation of a superior information system. The latter is essential for capitalizing on the rapid generation of test results. The planning for an automated laboratory entails much more than the operation of the system once it is installed. One of the difficulties in many laboratories is maintaining the daily processing and testing of specimens while a large part of the laboratory’s space is taken out of service during construction. An especially difficult area to manage is ensuring the loyalty and productivity of staff. This is particularly true when they are aware that one of the objectives of installing a robotized laboratory is to reduce labor costs, which must inevitably impact some of the staff whose goodwill and cooperation are essential. This also is essential during all of the steps before the successful introduction of routine operation of the system on a daily basis. A majority of the forum papers are presented here in their full-length form. Four other papers are summarized below that address key problems in working toward an automated laboratory. We believe that the meeting achieved its objective of presenting all of the issues that need to be recognized by a laboratory director before embarking on the very challenging and expensive pathway leading to total laboratory automation. Although this concept has been well accepted in Japan, the small number of installations in the US to date means that those laboratory directors who have installed systems are still pioneers. We are grateful that they were willing to share their experience at the 1999 Clinical Chemistry Forum. In addition, the attendees and the readers of these Proceedings need to recognize the dedication and support given by Jean Rhame and Pamela Nash of the American Association for Clinical Chemistry’s staff, who made the meeting happen. Implementation of total automation of a laboratory is a formidable task. Not only does it ultimately require a large expenditure of money, it requires time and perseverance on the part of its proponents. Two of the papers presented at this forum addressed the very practical issues of getting buy-in from constituencies as diverse as a hospital administration to all of the individuals whose jobs may be threatened by an automated system. A third paper summarized the necessary steps for the overall planning process, and a fourth paper highlighted the critical importance of information handling in a successful robotic facility. These papers are summarized below. Julie A. Fisher, Mount Sinai Medical Center, New York City, discussed selling the concept of a totally automated laboratory to a hospital’s administration and other stakeholders. Successful selling is based on extensive communication and detailed financial and other justifications. There are eight essential elements to successfully selling an automation concept. These are defining goals, assessing needs, obtaining stakeholder buy-in, the decision-making process, vendor selection, the financial planing process, implementation, and metrics. Continuous communication is essential throughout all phases of the project. The wishes of the laboratory must be congruent with those of the administration. The process may be protracted; the cycle between initial concept and routine operation may be as long as 6 years. The trigger for a laboratory to consider automation usually is pressure to reduce costs and improve its efficiency. Automation has the potential to enhance the economic survival of a laboratory, reduce its operating costs, improve the quality of services, and provide a safer work environment. The need for automation should be assessed in the context of whether the institution is planning to expand or to just cut costs. Every ramification must be considered. For example, contractual arrangements with unions must be taken into account. This will become particularly important when the system is fully implemented because contracts may determine who may or may not be laid off. Additionally, needs for upgrading or changing the laboratory information system and analytical instruments must be assessed. A successful automation project depends on stakeholder buy-in. The stakeholders include the laboratory staff, the hospital administration and Board of Trustees, and hospital physicians. It is important to communicate to each of the groups what automation will do for them. Each of these constituencies has different interests and concerns. The laboratory staff are most concerned about job security, but it is important to let them know that automation is a tool to help them perform their jobs differently, and perhaps better. For the administration and Board of Trustees, the focus needs to be on the financial bottom line, with emphases on the opportunity for both revenue enhancement and expense reduction. Other selling points for the administration can include the potential to perform tests for other hospitals and develop group purchasing arrangements with other hospitals for which laboratory services can be provided. Physicians are primarily concerned with turnaround times of test results as well as enhanced information. The financial planning process requires projections of revenue and expenses. A break-even analysis is essential and must demonstrate that automation will reduce costs and/or enhance revenue. Various approaches may be used. A traditional return on investment (ROI) analysis relates net income to investment capital. The formula for calculating a ROI may be refined to take into account sales as well, as in a DuPont analysis. This approach recognizes that it might not be beneficial to tie up assets, thereby lowering profitability. The same formula can be used for an expense analysis by keeping sales constant. The net profit margin increases with a reduction in expenses, and with automation, the key expense reduction is in labor. Technical productivity can be calculated by dividing the number of tests performed by the total number of paid full-time employees or equivalents (FTEs). The calculation of labor savings should take into account how the number of employees will be reduced. With layoffs, there often will be severance and/or retraining expenses to equip the laid-off employees for other jobs. Different laboratory areas will be affected differently. Thus, the laboratories in which automation will be implemented will be more impacted than others. For each laboratory area, a separate projection of staffing needs to be done. Recently, there has been a trend away from justifying automation solely on an ROI analysis because not all of the benefits can be quantified in financial terms. Automation provides added value through improved efficiency coupled with reduction in processing errors, improved turnaround times, automated repeat and reflex testing, enhanced safety, and improved specimen tracking. The active participation of stakeholders in the planning process enhances the laboratory’s ability to sell the concept. Thus, an overall executive committee derives benefits when supported by laboratory management with information systems and instrumentation teams. It is advantageous to enlist stakeholders in vendor selection because acceptance of the system is critically dependent on the their involvement. The more people involved in different aspects of the planning process, the greater the probability of acceptance. Even during the implementation phase, it is important to involve the stakeholders, especially the staff who will be directly affected by the system. During the installation and after the system becomes operational, it is important to continue to communicate to the stakeholders. Information that should be communicated includes actual performance compared with projections, especially with regard to revenue projections and/or expense reductions, the quality of service, and whether a safer environment has been created. Patricia Abbott, Hospital of the University of Pennsylvania (HUP), Philadelphia, discussed the practical aspects of creating a robotized laboratory. Because acceptance of laboratory automation by a hospital’s administration is, to a great extent, dependent on perceived financial benefits, an accurate estimate of the number of employees needed to operate the system is required. The greatest financial returns are likely to arise from reduced labor costs. Unfortunately, the estimate of the number of staff needed to operate a robotized laboratory must be made before the laboratory has any experience with the system or its impact. One of the first steps in the planning process is to decide which tests will be performed in the automated laboratory and which will be performed elsewhere. This decision requires not only an analysis of which tests are performed at each existing bench station but the proportion of tests requested stat vs routine per shift, the number of tests per shift, and the number of technologists working on each shift on each day of the week. With automation, it becomes feasible to combine the stat and routine workbenches for the high-volume tests, but for precise planning of staffing needs, the time of receipt of specimens in the laboratory must be considered. It is also necessary to consider physician needs in deciding which instruments should be interfaced with the robotized and to assess whether greater can be through the test on different analytical the of the planning process, it is essential to assess the and interests of the laboratory staff. This is especially important the laboratory been to a of separate laboratories because there may be a need for extensive of existing on the of the staff in the laboratory at it was to staff the automated laboratory with a staff who would be to operate all of the instruments in the and who would be by staff from the areas working in their areas of expertise. this the laboratory for example, be to on the of of the technologists who would be to operate only the in the automated laboratory to become in operating technologists who been to the and laboratories would not have to the needed to operate a was to assess the of the for working in the automated laboratory, it was on a small number of staff.

Thus, it is a approach to the management of costs, and However, it has only been management requires of a to and manage people and other One individual is to the and is given and to manage the project to its areas of or function are involved in project and the project should have and some in all of them. The primary areas involve the management of cost, and These are by the management of and management is concerned with the of the the overall and of management involves of the necessary the of and the for the project.
