Hospitals of the Future using Advanced Technologies Professor Rabee Mohamed Reffat Professor of Architecture and Digital Technologies, Architecture Department, Faculty of Engineering, Assiut University, Assiut, Egypt Email: [email protected] Abstract Todays’ challenges and priorities are driving healthcare systems to forge innovative solutions to manage the increasing expense and complex social burdens that increasing patients and chronic disease rates bring. Advanced technology is being rapidly adopted in health care facilities and is leading to changes in the way health care facilities are designed and built. Implementing advanced technologies requires a great deal of planning and a specialized construction expertise due to the requirements for accommodating sophisticated and advanced equipment. One of the visions that can be utilized to address the above issues is the Hospital of the Future that aims to transform health care to safe, cost effective, predictive, preventative, evidence based, and participatory system. The Hospital of the Future concept is established to share and accelerate development and findings related to technologies supporting future healthcare needs. The purpose of the Hospital of the Future is to improve patient safety, hospital design and interoperability. This paper addresses the concept of the Hospital of the Future, its potential benefits and constraints. The paper presents the Digital Hospital Framework developed by IBM as an approach to the utilization of the Hospital of the Future in order to achieve healthy, safe, efficient and environmentally responsible health care facilities. 1 1. Introduction A hospital is unique building type in terms of the high level of complexity in circulation patterns, constant use and diverse technical systems. A hospital delivers healthcare services to patients who may stay in overnight accommodations or may visit briefly for specific care. New advancements in radiology, aseptic germ theory, anesthetic surgery, and electronics and communications made the former nursing care facility into a highly specialized workshop for medical services. The hospital took on a new physical form, as a large dense building with many specialized parts. The ability to provide extended 24 hour care with a high level of complexity of medical services differentiates a hospital from other healthcare facilities. Successful hospital planning must be measured over a long term, not just as an inviting and attractive new building but as a structure that supports these intensive and demanding functions on a 24 hour/7 day basis over what is often more than a 50 year useful life. Since the hospital is place dedicated to health, its building must first be a healing, life-affirming space that plays an active role in helping patients and their families return to health. Hospitals of the future will need to plan for higher patient acuity, shorter stays, and must deal with aging patients and staff. Because of their long term operational costs and long life cycle, hospitals have to be designed for improved performance and work flow, and with a high degree of flexibility and adaptability for constant change. With round the clock use and high occupancy, and the need for high capacity and redundant building systems, a hospital is also a large energy consumer and a prime opportunity for the benefits of green and sustainable design. The detailed architectural and interior design philosophy of the future hospital needs to start with the feeling of hospitality, and of providing a link to nature and the world beyond. The design of hospitals has to provide a safe, comfortable environment, and reduce stress and confusion for patients, families, and staff. A successful design will recognize the dimensions of life as well as the needs of efficient operations and include art as well as technology. The design team needs from the outset to plan for sustainable design and reduced energy usage, which in a building that operates continuously is a major opportunity for lowering the carbon footprint of the service. To maintain a feeling of wellbeing and positive support for the needs of people, the hospital must also have clear, intuitive way finding and an easily understood layout (Sprow, 2012). 2. Designing Hospitals of the Future The physical design of the hospital has significant implications for the ability of the hospital to meet its goals for care that is safe, patient-centered, clinically effective and collaboratively delivered. It also represents the physical manifestation of the hospital’s commitment to environmental health and sustainability. There are factors that will be (to lesser and greater extents), out of the hospital’s control as the future unfolds. 2 Several studies have revealed hospital design characteristics that work for improving patient safety and health care outcomes, and providing a supportive environment for hospital staff. Yet, most new hospitals are not being built “safe by design.” Hospitals need to be designed to safely accommodate fragile patients. Prominent threats to patient safety include medication errors, patient falls, and errors made during patient transfers, which can be mitigated through evidence-based design. Better lighting and reduced noise levels can help avoid distractions that often lead to caregiver errors in the medication process. Decentralized nursing stations allow nurses to better see and hear the patients under their care and observe changes in skin color and breathing, as well as to prevent falls that occur when a patient is unobserved. Rooms that are designed for the patient bed and bathroom entrance to be seen from the hallway also enhance observation. Multi-acuity beds that reduce the number of transfers, or “hand-offs,” of patients from one unit to another, in turn, reduce the opportunity for errors to occur. The regulatory infrastructure can stifle design innovations meant to reduce the risk of patient injury. Though multi-acuity beds that allow a patient to remain in the same bed while their care level is stepped down from critical care to medical-surgical nursing may make sense, in some states they do not meet state licensure stipulations regarding patient bed designations and thereby are disqualified for reimbursement. Single-patient rooms may have the single most important impact on patient safety. In addition to enhancing patient privacy, allowing for confidential discussions and accommodating family members, single rooms help protect patients’ health. Some of the prime principles to guide the design of the Hospital of the Future include (TJC, 2008): Incorporate evidence-based design principles that improve patient safety, including single rooms, decentralized nursing stations and noise-reducing materials, in hospital construction Address high-level priorities, such as infection control and emergency preparedness, in hospital design and construction Include clinicians, other staff, patients and families in the design process to maximize opportunities to improve staff work flow and patient safety, and create patientcentered environments Design flexibility into the building to allow for better adaption to the rapid cycle of innovation in medicine and technology Incorporate “green” principles in hospital design and construction. 3. The Hospital of the Future: Motivations and Ideas The successful hospital of the future is one that efficiently delivers quality care and consistently improves clinical outcomes. The model hospital of the future will adopt workflows, policies, systems and solutions that optimize operational efficiencies. Integrating these disparate 3 systems, it will leverage software applications to enable the collection, management and analysis of patient and operational data. Armed with such actionable intelligence, administrators and caregivers will be able to incrementally improve their performance. In so doing, the hospital of the future will be able to deliver care faster, safeguard patient safety, and empower more human resources to be applied at the point of care (Swisslog, 2014). Sprow (2012) has identified some ideas driving the new hospital planning and design; some of which have been selected and reorganized as shown in Table 1. Table 1: Motivations and Ideas driving the hospitals of future (selected from Sprow, 2012) Motivations With more digital information being shared around the hospital network, and the desire for a patient visit which is as seamless and direct as possible, hospitals are now looking beyond departmental borders to think about how patients make appointments, how they arrive at the right location for their visit, and how clinical and financial information is captured and processed. Wayfinding is more than signs. A stronger management concern for the patient experience, as part of a market share focus, means that old systems such as endless standard signs (and even worse, colored stripes on the floor) are being replaced by more information, more interactive systems. Hospitals are routinely used for 50 years or more – but at the same time individual rooms may be changed or replaced after as few as seven years, as clinical methods and equipment change. The challenge is to plan for ease of use, good wayfinding, high technology and a healing environment, but without assuming that specific rooms will remain unchanged for very long. Hospitals with functional older facilities, often scattered on different floors or in different wings, are finding that it makes sense to invest in larger scale surgery facilities which are more productive and more flexible. Ideas Providing service concierges to direct patients, providing central registration points to capture basic information for the database only once, and using computer-assisted scheduling and management systems that track patient arrival times, length of wait, and final results. Electronic kiosks, computerized direction systems, and planning that is clear and modular, even without signs, are the new tools in helping patients and families navigate the hospital and to make it more accessible to them Hospitals are responding with an acceptance of more generic and modular space. Today’s pediatric exam room may later be part of a geriatric cardiology unit, or a new imaging suite, or relocated office functions in only a few years. Often it is more flexible and efficient to build a smaller number of larger but standardized rooms. Creating generic operating theatres, directly adjacent to highly flexible operative units which can function flexibly as pre-operative holding for ambulatory patients and recovery for ambulatory surgery and for inpatient. Rooms and recovery beds are grouped in clusters, so that staffing can follow peaks and valleys in the work load through the day. Surgical rooms are designed for multispecialty use as needed, with very few dedicated rooms. Operating theatres are also being rebuilt to include facilities for minimal-access surgery and telemedicine, with more flexible ceiling-mounted utility booms, and new generation lights which 4 Often the Emergency Department is the marketing front door and the starting point for a high percentage of patient admissions, and hospitals are very concerned about making it both more productive and more responsive to patient concerns. integrate efficient and flexible LED lighting, video cameras and flat-screen technology. New hybrid operating theatres blur the distinction between surgical and imaging functions and design requirements. One common approach is the single room treatment concept, which provides a large number of private treatment rooms so that each patient and their family are usually taken directly to one room for all of their treatment. Triage steps are minimized, and much of the admission process can be done directly in the room. The result is a patient experience of being seen and attended to almost immediately, rather than the typical story of being held in the waiting room for long periods of time. Satisfaction is much higher and flexible generic rooms can adapt easily to changes in utilization. Reducing the need for waiting room space allows for more functional space. 4. Advanced Technologies Shaping Hospitals of the Future Regardless of ongoing technology revolution, the visible and physical design of hospitals has changed less than one might imagine over the past decades. With a significant influx of new patients, and an aging existing hospital infrastructure, it is appropriate for health care leaders to think carefully about the next generation of hospitals. So, thinking about the hospital of the future includes patient-centered care, flexible space and evidence-based design which make great sense and should be pursued with vigor. These three themes typically dominate the discussions of the hospital of the future. Three other concepts also might be worth careful contemplation: the connected, service and value enterprises. The unifying theme is using clinical and information technology better, faster and smarter to integrate and make those three concepts come alive. In other words, advances in technology drive the hospital of the future as follows (Montagnolo, 2013): The Connected Enterprise: clinical care devices, information systems, workflow systems, and patient and family communication systems should integrate more seamlessly in both time and space. Numerous technological advances may help push this concept. For example, new sensor technologies will provide more real-time and mobile monitoring. Instead of a nurse taking a patient’s blood pressure and pulse periodically, a mobile sensor monitors those vital signs continuously. And instead of a patient checking his or her blood glucose, a portable sensor monitors it continuously. When changes happen, the information becomes available in real time to the entire care team. Further, telepresence robots already can help extend the reach of care teams so that all members are able to interact in real time with patients. The mindset shaping the 5 hospital of the future should be better integrated space, technology and processes all focused on seamless communication during, rather than following, care delivery. The Service Enterprise: The hospital of the future must treat service as a central principle and embed it in all the workflows throughout the enterprise, from delivering meals to transplanting organs. Great service relies on helping staff do their jobs effectively and efficiently; consistently delivering the desired outcome; and treating patients in a manner that acknowledges their humanness, not simply their biological status. The hospital of the futures solves this by tackling issues such as patient alarms. The Value Enterprise: Hospitals must acquire clinical and information technology to create the value enterprise. They must improve outcomes and the patient experience while creating cost-efficiencies that help the masses and the government to afford care. Adopting new clinical or information technologies, and using existing clinical or information technologies can make a difference right now. Moving imaging closer in time and space to where it is most urgently needed, for example, would improve outcomes. If imaging and real-time data analytics are combined, unnecessary or redundant imaging studies will be eliminated. Todays’ challenges and priorities are driving healthcare systems to forge innovative solutions to manage the increasing expense and complex social burdens that increasing patients and chronic disease rates bring. In both developed and emerging economies, the healthcare infrastructure is transforming to address the steady rise in both healthcare demand and costs. In emerging economies such as those in China, India, the Middle East and Latin America, stateof-the-art hospitals and medical centers are being built or retrofitted to meet these challenges. To deliver the highest quality care to meet the needs of their communities, integrated health systems are leading in the transformation of healthcare, migrating from its traditional focus on acute care episodes toward providing more coordinated, patient centered care. Fundamental to this transformation is the digital infrastructure (known as information and communications technology – ICT), that enables information sharing among healthcare providers, payers and patients. However, deployment of such technologies within the industry has been slow and uneven across various areas of hospital operations. Automation of hospital administrative processes, such as patient registration, admission, and discharge is relatively widespread. Yet fully digital hospitals that run the gamut of clinical applications and advanced hospital information systems interconnected by a robust and reliable infrastructure are exceptions rather than the rule. Digital hospitals, whether newly-built or existing operations retrofitted with the latest digital information technology, promise to boost efficiency and quality through better integration with all sources of care. They are enabling deployment of eHealth systems that provide online information, disease management, remote monitoring and telemedicine services that can extend the reach of scarce medical resources and expertise. Digital hospitals 6 provide faster and safer throughput of patients, creating more capacity through process efficiencies, while containing costs. Examples of benefits include (IBM, 2013): Improved patient outcomes, as measured by reduced length of hospital stay, readmission rates and other key metrics Safer, healthier, green environments and medical workplaces that help attract worldclass medical talent Improved consumer service and patient satisfaction Decreased documentation and administration effort, while increasing staff satisfaction Broad improvements in healthcare access, quality, safety and sustainability Improved operational efficiencies and decreased capital expenditures A digital hospital is one that implements a comprehensive, pervasive IT infrastructure to enable clinical and administrative workflow and communications as well as process and quality improvements. It expands those process improvements beyond the hospital’s four walls and into the community, providing connectivity and collaboration with physician offices and other remote healthcare organizations and even extending its digital reach into patient homes and emergency medical services. In a digital hospital, various advanced technologies, such as critical medical devices, intelligent information systems, facility control systems, automated transport systems, location-based services and sensors, and digital communication tools, provide a fully integrated set of applications and services that improve staff productivity, hospital operations, process quality, patient safety, and overall patient experience. The digital hospital journey can begin with one or more change initiatives, each representing a different set of circumstances and considerations. A number of potential changes that could initiate the digital hospital journey are shown in Figure 1. Regardless of the starting point, the guiding principles are the same: functional integration is critical, as is the innovative use of information systems; process redesign that maximizes the value of IT-enabled process improvements is also essential; and a strong partnership with technology suppliers is a key to long-term success. Organization commitment, sound planning, effective implementation management, and end-user commitment to the technologies are all vital to a successful journey (Duffy and Holland, 2009). 7 Figure 1: The IBM Digital Hospital Framework: An approach to the Hospital of the Future (Duffy and Holland, 2009) Digital hospitals are complex ecosystems with hundreds of clinical and business processes made up of thousands of sub-processes. When properly integrated, these processes should seamlessly unite patients, clinicians, staff, assets and information throughout the hospital, delivering the right information and resources at the right time to the point of care. Essential to this integration are the ICT that interconnects all aspects of care delivery and administration. New hospitals take an average of three to five years to build, while existing hospitals that are retrofitted with the prerequisite pervasive, medical grade networks and multi-modal digital communications can take as long as five to ten years to completely modernize. In addition to digital medical devices and continuously available high-speed networking infrastructure, hospitals must reengineer business processes to create paperless automated workflows. Electronic medical records, including Computerized Physician Order Entry (CPOE) and access to medical imaging, must be integrated seamlessly, while the decomposition, redesign and planning of clinical and business processes must start early in the cycle, even before the specification and selection of technology. Whether planning the development of new acute care and ambulatory facilities or modernizing aging technology infrastructure of existing hospitals, healthcare executives and their boards must endorse the big picture, understanding how departments interact within an enterprise and how different facilities across diverse care settings must work in a coordinated health system. Understanding the dependencies and relationships between various IT programs and initiatives can help healthcare decision makers cope with the complexity of the numerous solutions and choices available to them. For example, implementing an electronic health record system that allows laboratory results and diagnostic images to be viewed at the bedside may require upgrades to the wired and wireless 8 network infrastructure and changes to enterprise storage capacity. Real-time location tracking technologies, including infrared and radio frequency identification (RFID) might have a dual use; improving clinical care by reducing time to locate equipment or implementing a closed-loop medication management system while supporting the tracking of assets in order to optimize asset capital requirements. The framework illustrated in Figure 1 represents the various categories and components of IT networks and storage and electronic health records and care orchestration systems and the like can help executives understand how the IT elements in the framework relate to their larger strategic objectives (IBM, 2013). Figure 2: The IBM Digital Hospital Framework: An approach to the Hospital of the Future (IBM, 2013) Some of the potential benefits of the highly efficient Digital Hospital are that hospitals will be equipped to handle twice as many patients with a higher level of care and safety without increasing hospital or staff size. It can track patients, staff and assets anywhere and at any time in the hospital. Advanced Technologies will facilitate the link of diverse and complex processes to save time, money and effort while greatly improving outcomes and the patient experience. Wireless technologies such as hand-held communications devices and smartphones that track patients and resources are already transforming the healthcare environment. Real-time location services tracks medical assets, equipment, patients, and staff to help improve asset utilization and improve overall patient safety and quality of care. 9 On the other hand, deploying new or enhanced technology in any environment can be a very difficult task. This is more difficult in the healthcare environment that is composed of wide and diverse stakeholders. Thacker (2011) introduced a set of the best practices that should be incorporated into the proposed technology and its implementation process which will greatly enhance the chances of success. This set of best practices includes: Gathering and developing the comprehensive requirements of stakeholders Documenting the existing processes before developing the requirements Selecting and developing systems with integration in mind Selecting and developing systems that are flexible and can be expanded to meet new requirements Developing systems that focus on providing accurate and actionable data and outcomes to all stakeholders 5. Conclusion For the hospitals of the future, it is most important is to focus on a planning process leading to form not on designing an architectural idea first. It is also critical to think in terms of an open system of planning in which variables such as required services, anticipated volume, operational and staffing assumptions and building system decisions could all be adjusted and tuned as needed while keeping in mind the basic goal of a high quality, low upkeep, flexible and expandable hospital concept which can be an expression of a new hospital type for world use. Helping clinicians and caregivers become more efficient in the hospital of the future should be as important as purely improving patient outcomes because clinician efficiency allows room for concentrating behaviors and time on new areas of value. Better patient outcomes for individuals and better population health for communities become the ultimate benefit of the virtuous circle of continuous improvement. In hospitals that embrace the concepts of patient centered care and support the development of their workforce, no one should be neglected. The application of digital technologies will extend the reach of hospital care into the community and into the home and will potentially help to achieve for healthy, safe, efficient and environmentally responsible hospitals using the digital hospital framework and its associated advanced technologies t. The hospital of the future may one day be defined by its intellectual property rather than its physical facility. 6. References 1.
