The VATAM guidelines.

Evaluation and assessment of the impact of information and communication technology in medicine is gaining interest. Unfortunately, till now there were no agreed upon approaches. The objective of the VATAM project is to develop guidelines that will assist assessors to set-up and execute studies. This paper describes the background of the VATAM project and provides an account of the current state of the guidelines. It concludes with an indication of the developments that will take place in the short term to further elaborate the guidelines and some considerations for consolidation of VATAM's results.

The behavioral side of information technology.

Exposure to technologies is becoming more prevalent in healthcare technologies. Few strategies have been developed that work reliably to successfully implement information technologies. Information technology enables, but does not guarantee organizational change. A theoretical model has been developed identifying several areas that have been found important in information technology implementation. The information technology adoption model is described, and provides a framework for implementors of information technologies. It provides a structure to categorize areas that may benefit from the development of implementation strategies and the development of evaluation techniques. Implementation and evaluation strategies are discussed as they pertain to end-user fit, user perceptions of innovation usefulness and ease of use, and adoption and utilization.

Health informatics as a tool to improve quality in non-acute care--new opportunities and a matching need for a new evaluation paradigm.

Whilst most health care is delivered to people living at home, the focus of innovation in health informatics concepts has been largely on acute hospitals. However, delivery of services in community settings, and often related to long-term conditions, is complex, and involves multiple professions and agencies, delivery of care in several locations including home settings, and individually tailored care for episodes lasting over long periods of time. This challenge is poorly supported by current information systems. However, computer-based record systems have a major potential to improve quality of care by enabling integrated care delivery through multi-professional electronic patient records, whilst also providing quality assurance processes. In turn, though, this requires a new evaluation paradigm. Firstly, the multi-disciplinary and holistic ideal of integrated care requires an as yet inadequately developed framework to give structure to assessment of the value and utility of the data recorded and the way in which they are processed and presented, mapped to clinical processes and to the views of consumers as prime stakeholders. Secondly, a deeper and longer-term evaluation philosophy is needed which does not stop after the initial confirmation of system functioning, but continues on with a deepening into the effects on the individual clinical services, and then on the host user organisation. This paper maps out the new paradigm, and suggests specific issues which merit practical research to reset evaluation and assessment tools to this new setting and viewpoints.

Information technology as tool for change.

It looks that networking welfare thinking and implementations of network projects only follow the development of data transfer possibilities. It is a danger that seamless chain of care in health care is just a data transferring generator based on easy connections, only creating needs for new data transferring. This is an 'illusion of core skills' that does not extend to the development of the contents of services. Easy access to the system makes more contacts and need for more also clinical services. New needs for data transfer burden the personnel with unnecessary information and networking functional model does not emancipate them to use their substantial skills. It means more costs and it is also a danger that normal life will be medicated. Public sector cannot finance all these new possibilities and consequences of modern technology. Does all this create a new combination of public and private sector and push them to allocate responsibilities in developing work? If the public and private sectors do not find the balance in controlling this development, also actors outside health care get to influence the choices and health care loses its autonomy. It becomes a business means for companies producing data transfer and network services. From the prioritization point of view this is not a good vision for financing and delivery of health care services either in public or private sector.

IT, change and evaluation: an overview of the role of evaluation in health services.

Effective evaluation is important for appropriate deployment and use of information technology, especially in the current environment of changing health services. However, the broad range of roles and environments in which technology is used challenges traditional evaluation approaches. As technology has progressed, these roles have developed to the extent that information technology is now often playing a very complex role in health service organisations. In such cases there are many uncertainties in decisionmaking that are difficult to address with traditional formal evaluation techniques. There is a need to recognise and work with more complex, socially constructed decisionmaking process relying substantially on a variety of human judgements. The need for this recognition is demonstrated by exploring the difference in our ability to analyse a range of different systems, considering the role of complexity, uncertainty, theory, change and control. There is the need, then, for evaluation processes to complement these social decisionmaking processes, rather than to replace them. The nature of these processes needs to be effectively understood to enable the most appropriate types of evaluations to be undertaken. A number of different scenarios are explored to demonstrate the types of roles that evaluation may need to take.

Methodological approaches of health technology assessment.

In this era of evolving health care systems throughout the world, technology remains the substance of health care. Medical informatics comprises a growing contribution to the technologies used in the delivery and management of health care. Diverse, evolving technologies include artificial neural networks, computer-assisted surgery, computer-based patient records, hospital information systems, and more. Decision-makers increasingly demand well-founded information to determine whether or how to develop these technologies, allow them on the market, acquire them, use them, pay for their use, and more. The development and wider use of health technology assessment (HTA) reflects this demand. While HTA offers systematic, well-founded approaches for determining the value of medical informatics technologies, HTA must continue to adapt and refine its methods in response to these evolving technologies. This paper provides a basic overview of HTA principles and methods.

Usability in the real world: assessing medical information technologies in patients' homes.

OBJECTIVE: This paper presents an approach to usability evaluation of computer-based health care systems designed for patient use in their homes. Although such devices are becoming more prevalent, there is very little known about their usability. DESIGN: The theoretical foundations for the methods are discussed. The approach incorporates a cognitive walkthrough usability evaluation and new methods for usability testing that can be conducted in patient's homes. The method was applied to the IDEATel intervention, a multi-institution randomized controlled trial of the feasibility, acceptability, and clinical utility of a home-based telemedicine system for diabetic Medicare population. The usability study was designed to assess barriers to optimal use of the system. The focus was both on dimensions of the interface and on dimensions of patient skills and competency. The usability field research involved testing 25 patients in their homes using the system. The analysis included a range of video-analytic methods of varying levels of granularity. RESULTS: The usability evaluation revealed aspects of the interface that were sub-optimal and impeded the performance of certain tasks. It also found a range of patient-related factors such as numeracy and psychomotor skills that constituted barriers to productive use. CONCLUSIONS: A multifaceted usability approach provided important insight regarding use of technology by an elderly chronic-care patient population and more generally, for understanding how home health initiatives can more effectively use such technology.

Translating traditional principles of system development into a process for designing clinical information systems.

Traditional software development methodologies enhanced by a clinical component result in information systems that support the practice of nursing. This paper describes the clinical informatics model used to develop and evaluate a mobile computer assessment tool. Data entry of atomic-level elements, with storage in a relational database, allows the synthesis and analysis by multiple disciplines to aid in real-time decision making. The system is designed to improve the recording and accessibility of patient data and nursing observations on a geriatric unit at the Salt Lake VA Medical Center.

Evidence-based medicine and psychiatric practice.

Evidence-based medicine (EBM) has been defined as "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients." EBM requires the ability to apply a knowledge of medical informatics (e.g., efficiently searching the medical literature) and clinical epidemiology (e.g., being able to critically appraise the literature) to the treatment of individual patients. This article provides an introduction to the history, philosophy, and methods of EBM as applied to psychiatric practice. The article summarizes the five-step EBM model: (1) formulate the question; (2) search for answers; (3) appraise the evidence; (4) apply the results; and (5) assess the outcome. Resources (including Web sites) for further learning are provided.

The impact of medical technology on office workflow.

Digital technologies are gaining wider acceptance within the medical and dental professions. The lure of increased productivity and improved quality entice practices to adapt. These systems are beginning to have a profound impact on the workflows within the practice, as well as putting new demands on existing resources. To successfully implement a new technology within your practice, you must look beyond advertising and discover the real requirements of the system. Vendors rarely try to help beyond the sale and installation of their equipment, nor do they consider how their product might require you to modify the way you and your staff work. Acquiring the necessary knowledge through self-education, a consultant, or (preferably) a combination of the two is the best way to integrate a new technology with your practice.

Usage of the Internet pharmacology resources among European pharmacologists: a preliminary investigation.

The Internet is becoming an ever more important source of information in pharmacology and medicine. Little is known, however, about which Internet pharmacology resources are actually used by the pharmacologists - and to what extent - and how they estimate the Internet information quality and evaluation. This pilot study used an anonymous questionnaire, distributed among 250 mostly European (220/250) pharmacologists from 30 European countries attending The 2nd European Congress of Pharmacology, held in Budapest, Hungary, in 1999. According to study results, 93% of all participants use the Internet pharmacology resources: 56%, 35% and 9% of them on a daily, weekly and monthly basis, respectively. Among 56 pharmacological/medical free online databases offered, the general scientific databases were found to greatly prevail (Pub Med 60%, Evaluated MEDLINE 37%, Internet Grateful Med 29%, etc.), while drug monographs or toxicological databases were less used [e.g. ECDIN, RxList, National Toxicology Programme (NTP) < 10%]. Some 80% of the participants estimated the quality of the pharmacological information on the Internet as good or very good, while 20% thought the quality should be improved. Also, 35% of participants felt the need for improvement of the Internet pharmacological information evaluation, which should be the goal of pharmacology professional.
