Virtual automation.

Total laboratory automation (TLA) can be substituted in mid-size laboratories by a computer sample workflow control (virtual automation). Such a solution has been implemented in our laboratory using PSM, software developed in cooperation with Roche Diagnostics (Barcelona, Spain), to this purpose. This software is connected to the online analyzers and to the laboratory information system and is able to control and direct the samples working as an intermediate station. The only difference with TLA is the replacement of transport belts by personnel of the laboratory. The implementation of this virtual automation system has allowed us the achievement of the main advantages of TLA: workload increase (64%) with reduction in the cost per test (43%), significant reduction in the number of biochemistry primary tubes (from 8 to 2), less aliquoting (from 600 to 100 samples/day), automation of functional testing, drastic reduction of preanalytical errors (from 11.7 to 0.4% of the tubes) and better total response time for both inpatients (from up to 48 hours to up to 4 hours) and outpatients (from up to 10 days to up to 48 hours). As an additional advantage, virtual automation could be implemented without hardware investment and significant headcount reduction (15% in our lab).

Knowledge integration: insight through the E-portal.

Data become information when they can be summarized and organized into logical patterns; information becomes knowledge when it can be manipulated for actionable decision making; knowledge becomes insight when contextually relevant and temporarily appropriate. This article describes how information technology can now be used to provide clinicians with access to both insight and information that is context- and event-sensitive. Collaboration between the American College of Physicians, medical knowledge experts, Oregon Health Sciences University (OHSU), and shared medical systems for framework and infrastructure combine to create the ideal environment of complementary and synergistic competencies. This article describes the research that is under way at OHSU to determine how to deploy medical knowledge derived from these sources and integrate it into the clinical workflow; it also examines a vision of how medical knowledge can be integrated in the future.

ERP (enterprise resource planning) systems can streamline healthcare business functions.

Enterprise resource planning (ERP) software applications are designed to facilitate the systemwide integration of complex processes and functions across a large enterprise consisting of many internal and external constituents. Although most currently available ERP applications generally are tailored to the needs of the manufacturing industry, many large healthcare systems are investigating these applications. Due to the significant differences between manufacturing and patient care, ERP-based systems do not easily translate to the healthcare setting. In particular, the lack of clinical standardization impedes the use of ERP systems for clinical integration. Nonetheless, an ERP-based system can help a healthcare organization integrate many functions, including patient scheduling, human resources management, workload forecasting, and management of workflow, that are not directly dependent on clinical decision making.

BPR (business process redesign) and systems analysis and design: making the case for integration.

The question of what role business process redesign (BPR) should play in information systems development is one that draws strong opinions on either side of the issue. Some argue that BPR is absolutely necessary in forging a synergy between organizational structure, people, technology, and tasks. However, consultation and application development continue today without sufficient workflow analysis, as if BPR was irrelevant altogether. This article examines major BPR theories and the similarities and differences between BPR and information systems development and engages in a discussion of the merits of including BPR in any information systems development project.

Automation and high through-put for a DNA database laboratory: development of a laboratory information management system.

Automation and high through-put production of DNA profiles has become a necessity in every DNA database unit. In our laboratory we developed a Laboratory Information Management System (LIMS) controlled workflow architecture, which comprises a robotic DNA extraction- and pipetting-system and a capillary electrophoresis unit. This allows a through-put of 4,000 samples per person per year. Improved sample handling and data management, full sample- and batch-histories, and software-aided supervision of result data, with a consequent average turn-around time of 8 days, are the main features of our new system.

Use of handheld computers as bedside information providers.

Access to clinical reference information at the point-of-care is a goal that is difficult to achieve by lack of really portable reference material. Handheld computers have matured to the point where they are powerful enough to be used as clients of a distributed knowledge system serving reference information and decision-aid applications in a highly portable form factor. We describe a pilot project launched at the Geneva University Hospital studying the use of handhelds and associated clinical applications in two internal medicine clinics. Results garnered by this study will help answer the many questions raised by the use of handhelds in medical practice, in term of cost, benefits, risk and change in workflow.

Simulation of a stroke unit careflow.

This paper describes the development and use of a simulation model representing part of the medical practice within a Stroke Unit. In particular, we modelled the medical activities as described in a guideline for the ischemic stroke treatment, adopted by the Stroke Unit of our hospital. The Petri net formalism has been chosen for the model representation. The numerical parameters have been estimated both using a database of about 100 patients collected during the last two years, and eliciting knowledge from the neurologists. A commercial tool was used for performing simulations, while ad-hoc routines were written for tailoring the result presentation to the specific context. We consider simulation a very useful preliminary step for the subsequent implementation of a patient workflow (careflow) management system. In fact, simulation is based on the process model (the clinical practice guideline) and on the organisation model (human and technological resources), so allowing to detect bottlenecks in the care delivery organisation and to find the optimal resource allocation. For example, we show that simulation has been able to find some of the causes of the delay in the patients treatment, and accordingly, to suggest changes in the organisation.

Digital photography technology offers unique capabilities, advantages, and challenges to dental practices.

Digital photography technology has both advanced substantially in the past few years and decreased in price. Today, high-resolution cameras offer an attractive option to dentists ready to incorporate digital photography into their practices. This article begins with a technical explanation of how digital photography works as the basis for understanding how it compares and contrasts with film photography, as well as how it offers unique benefits to dental practices. It describes how digital camera design affects image characteristics such as resolution and color fidelity and provides dentists with suggested camera features they should consider. The article explores issues associated with the display and storage of images. It then provides guidelines to help dentists determine whether they are ready to adopt digital photography, including a discussion about the advantages of digital photography as well as suggested ways digital photography will affect office workflows and productivity.

Assessing physician attitudes regarding use of an outpatient EMR: a longitudinal, multi-practice study.

A pre- and post-implementation assessment of physician attitudes was undertaken as part of the evaluation of the pilot implementations of an outpatient EMR in 6 practices of a large academic health system. Our results show that these physicians are ready adopters of computer technology when it demonstrates value-added for the effort required to use it. These physicians utilize email, the Internet, remote access to computer systems, and personal productivity software because they serve a valuable purpose in their academic and clinical work and in their personal lives. Much more critical to the acceptance of an EMR by physicians is its ability to facilitate efficient clinical workflows without negative effects on the valued relationships physicians have with their patients--those that are based on rapport, quality of care, and privacy.

Attitudes of academic-based and community-based physicians regarding EMR use during outpatient encounters.

Physician satisfaction with EMR implementations has been reported in a number of recent studies. Most of these have reported on implementation of an EMR in a uniform practice setting rather than comparing satisfaction with implementation between settings. Our objectives in this study were to: 1) compare and contrast the attitudes of academic-based and community-based primary care physicians toward EMR use 6 months after implementation, and 2) investigate some of the factors influencing their attitudes toward the EMR implementation. Although physicians in both settings regularly use computers, the academic-based physicians use computers for a wider range of activities. Both groups endorse improvements in quality and communication as well as concern over rapport with the patient and privacy. There is considerable discrepancy between the two settings in ratings of the impact on workflow, with the community-based physicians being much more positive about the EMR. Factors that may account for this discrepancy may include overall expectations of computer systems as well as different rates of adaptation to use of the system.

PDA support for outpatient clinical clerkships: mobile computing for medical education.

This project provides educational support for students enrolled in a family practice clerkship by supplying PDA-based clinical references and tools to collect information about the patients they see and the seminars they attend. Each student is supplied with a Handspring Visor Deluxe to use during the clerkship. Supplied software includes a clinical reference (Five Minute Clinical Consult) and Lexidrugs drug reference and a medical calculator. The data collection software consists of a patient log for recording simple demographic and diagnostic information about each patient seen during the clerkship, a seminar evaluation module for recording student feedback about each didactic presentation during the course, and an evaluation form where they students supply their reactions to the use of the Visor. Despite encountering a number of problems, the devices appear to be beneficial tools. The applications provide useful references for students who do not have access to the resources of the University in their family medicine clerkship. They also provide an improved, though not perfect, means to capture data regarding patient encounters and course evaluations. However, the challenge remains to better integrate the PDA with the student s workflow in the clinic.

Requirements development for a patient computing system.

Critical parts of the software development life cycle are concerned with eliciting, understanding, and managing requirements. Though the literature on this subject dates back for several decades, practicing effective requirements development remains a current and challenging area. Some projects flourish with a requirements development process (RDP) that is implicit and informal, but this approach may be overly risky, particularly for large projects that involve multiple individuals, groups, and systems over time. At Partners HealthCare System in Boston, Massachusetts, we have applied a more formal approach for requirements development to the Patient Computing Project. The goal of the project is to create web-based software that connects patients electronically with their physician's offices and has the potential to improve care efficiency and quality. It is a large project, with over 500 function points. Like most technological innovation, the successful introduction of this system requires as much attention to understanding the business needs and workflow details as it does to technical design and implementation. This paper describes our RDP approach, and key business requirements discovered through this process. We believe that a formal RDP is essential, and that informatics as a field must include proficiencies in this area.

Preparing a business justification for going electronic.

Exponential advances in the technology sector and computer industry have benefited the science and practice of radiology. Modalities such as digital radiography, computed radiography, computed tomography, magnetic resonance imaging, ultrasound, digital angiography, and gamma cameras are all capable of producing DICOM compliant images. Text can likewise be acquired using voice recognition technology (VRT) and efficiently rendered into a digital format. All of these digital data sets can subsequently be transferred over a network between machines for display and further manipulation on workstations. Large capacity archiving units are required to store these voluminous data sets. The enterprise components of radiology departments and imaging centers--radiology information systems (RIS) and picture archiving and communications systems (PACS)--have thus undergone a transition from hardcopy to softcopy. When preparing to make transition to a digital environment, the first step is introspective. A detailed SWOT (strengths, weaknesses, opportunities and threats) analysis, with a focus on the status of "electronic preparedness," ensues. The next step in the strategic planning process is to formulate responses to the following questions: Will this technology acquisition provide sufficient value to my organization to justify the expense? Is there a true need for the new technology? What issues or problems does this technology address? What customer needs will this technology satisfy today and tomorrow? How will the organization's shareholders benefit from this technology? The answers to these questions and the questions that they in turn generate will stimulate the strategic planning process to define demands, investigate technology and investment options, identify resources and set goals. The mission of your radiology center will determine what you will demand from the electronic environment. All radiology practices must address the demand of clinical service. Additional demands based on your mission may include education and research. The investigation of options is probably the most time consuming portion of the analysis. It is in this stage where the system architecture is drafted. Important contributions must be solicited from your information technology division, radiologists and other physicians, hospital administration and any other service where the use of imaging technology information is required and beneficial. Vendors and consultants can be extremely valuable in generating workflow diagrams, which include imaging acquisition components and imaging display components. A request for proposal (RFP) may facilitate this step. A detailed inventory of imaging equipment, imaging equipment locations and use, imaging equipment DICOM compatibility, imaging equipment upgrade requirements, reading locations and user locations must be obtained and confirmed. It is a good idea to take a careful inventory of your resources during the process of investigating system architecture and financial options. An often-ignored issue is the human resource allocation that is required to implement, maintain and upgrade the system. These costs must be estimated and included in the financial analysis. Further, to predict the finances of your operation in the future, a solid understanding of your center's historical financial data is required. This will enable you to make legitimate and reasonable financial calculations using incremental volumes. The radiology center must formulate and articulate discrete clinical and business goals for the transition to a digital environment that are consistent with the institutional or enterprise mission. Once goals are set, it is possible to generate a strategic plan. It is necessary to establish individual accountability for all aspects of the planning and implementation process. A realistic timetable should be implemented. Keep in mind that this is a dynamic process; technology is rapidly changing, as are clinical service demands and regulatory initiatives. It is therefore prudent to monitor the process, make appropriate revisions when necessary and address contingencies as they arise.

The nursing shortage: can information technology help?

There is no doubt that the nursing shortage is a real and valid concern for the medical community. American Hospital Association President Dick Davidson reports: "America needs up to 126,000 nurses now, as well as more pharmacists, lab technicians, support staff and others. We need immediate action to help alleviate this situation" (American Hospital Association, 2001). Clinical information systems can be one of those immediate actions that can help nurses feel more confident about the care they are delivering. In addition to preventing medical errors, streamlining workflow and communications, and reducing redundant data entry, these systems can have a lasting and positive effect on overall job satisfaction, providing a significant influence on retaining our invaluable nursing resources.

[Aa DICOM based PACS for nuclear medicine].

The installation of a Radiology Information System (RIS) connected to a Hospital Information System (HIS) and a Picture Archiving and Communications System (PACS) seems mandatory for a nuclear medicine department in order to guarantee a high patient throughput. With these systems a fast transmission of reports, images to the in- and out-patients' wards and private practitioners is realized. Therefore, since April 2000, at the department of nuclear medicine of the university of Würzburg a completely DICOM based PACS has been implemented in addition to the RIS. With this system a DICOM based workflow is realized throughout the department of nuclear medicine for reporting and archiving. The PACS is connected to six gamma-cameras, a PET scanner, a bone densitometry system and an ultrasound device. The volume of image data archived per month is 4 GByte. Patient demographics are provided to the modalities via DICOM-Worklist. With these PACS components a department specific archive purely based on DICOM can be realized. During the installation process problems occurred mainly because of the complex DICOM standard for nuclear medicine. Related to that is the problem that most of the software implementations still contain bugs or are not adopted to the needs of a nuclear medicine department (particularly for PET). A communication software for the distribution of nuclear medicine reports and images based on techniques used for the worldwide web is currently tested.

Field experience with the FAA's Web-based medical certification system "AMCS/DIWS". Federal Aviation Administration.

The October 1, 1999, introduction in the U.S. of a Web-based medical certification process for civil aircrew opened a new era within civil aviation. The Federal Aviation Administration's (FAA) Aeromedical Certification System/Document Imaging Workflow System (AMCS/DIWS) has imposed certain new requirements on the designated Aviation Medical Examiners (AMEs), including the use of Internet systems and procedures. A number of AMEs elected to discontinue their work as the classic medical certification processes were replaced. The authors document their personal experience with respect to the new system, and cite the overall advantages that modernized medical certification procedures bring. These advantages include far fewer "mistakes of omission" by AMEs, more timely receipt by the FAA of aircrew certification data, and a developing master aircrew database for analytic studies.

Internet-based search tools can help reduce bad debt.

The healthcare industry wrote off more than $20 billion in bad debt in 1999 alone, according to one estimate. Bills frequently do not reach patients because healthcare organizations do not have accurate patient contact and billing information. Incorrect billing information can be easily and inexpensively corrected by using Internet-based search tools. Healthcare accounts receivable staffs are using these tools to improve the patient experience and the bottom line with no capital outlay, minimal staff training or workflow change requirements, and low cost.
