Recent applications of a computer based modelling system for biomechanical interactions.

We discuss developments in our previously reported system for the modelling of the biomechanical interaction between people and products. The mass properties of the artefact are obtained and used to construct a computer model which includes both an android modelling the user and the product. This system developed as part of of a continuing collaboration, initially focussed on design methodologies in rehabilitation engineering. A description of the techniques used is given in our paper and related to ergonomics and occupational biomechanics after validating the approach in a pilot study we subsequently proposed to include a wider range of consumer products while continuing the work on rehabilitation engineering. Examples from case studies are investigated and used to refine the technique. These progressed from a heavy concrete breaker through to the design of domestic electrical; appliances, in the latter work although the loadings are not excessive in general use there are situations, especially those involving specific users such as elderly people, in which the design of the product may be inappropriate In each case we construct a model from the anthropometric data and refine the model where necessary to take into account special constraints imposed on the user. Recent results together with refinements to our technique are discussed.

Computer literacy in today's medical center environment.

The need for computer literacy is becoming increasingly important across the broad scope of the American work scene. At the Wilford Hall USAF Medical Center (WHMC) numerous computer systems have been introduced into the operational environment. Training for these systems has been restricted primarily to transaction processing and routine report generation for those actually involved as users of these systems. WHMC has developed and implemented a broad computer literacy program designed generally to raise the computer literacy of the overall staff, and specifically to inform executive and middle management of the general capabilities of the computer systems. The program consists of a brown-bag lunchtime videotape theater on a series of computer-related subjects as well as formal classes developed in a modular format. Each formal class is tailored to the specific needs of the target executive or middle-management group.

Hepatitis C infection among injecting drug users attending the National Drug Treatment Centre.

During a one year period from August 1992 to August 1993, 272 injecting drug users attending the National Drug Treatment Centre were tested for antibody to Hepatitis C Virus with a second generation EIA test. The overall sero-prevalence was 84% (N = 229). A significantly greater proportion of females tested positive than males (Female: Male, 94% v 80%, p < 0.012). Looking at sero-prevalence of Hepatitis C in relation to duration of intravenous drug misuse, we found that in those patients with a duration of misuse of greater than two years (N = 156) the sero-prevalence was 95% and in those with a duration of intravenous drug misuse of less than two years (N = 116) the sero-prevalence was 70%. We conclude that needle sharing continues to occur among injecting drug users during their first two years of injecting, despite the existence of harm minimization programmes. Our results would suggest that female injecting drug users are involved in greater at risk behaviour in relation to Hepatitis C than their male counterparts.

Process reengineering: the role of a planning methodology and picture archiving and communications system team building.

The acquisition of a picture archiving and communications system (PACS) is an opportunity to reengineer business practices and should optimally consider the entire process from image acquisition to communication of results. The purpose of this presentation is to describe the PACS planning methodology used by the Department of Defense (DOD) Joint Imaging Technology Project Office (JITPO), outline the critical procedures for each phase, and review the military experience using this model. The methodology is segmented into four phases: strategic planning, clinical scenario planning, installation planning, and implementation planning. Each is further subdivided based on the specific tasks that need to be accomplished within that phase. By using this method, an institution will have clearly defined program goals, objectives, and PACS requirements before vendors are contacted. The development of an institution-specific PACS requirement should direct the process of proposal comparisons to be based on functionality and exclude unnecessary equipment. This PACS planning methodology is being used at more than eight DOD medical treatment facilities. When properly executed, this methodology facilitates a seamless transition to the electronic environment and contributes to the successful integration of the healthcare enterprise. A crucial component of this methodology is the development of a local PACS planning team to manage all aspects of the process. A plan formulated by the local team is based on input from each department that will be integrating with the PACS. Involving all users in the planning process is paramount for successful implementation.

Towards a continuous evolution and adaptation of information systems in healthcare.

OBJECTIVES: To address the problem of alignment of health information systems to healthcare processes, which is a major challenge in healthcare organizations; to present a layered approach for system evolution and adaptation based on an application framework and rapid application development; to accomplish a demand-driven system evolution by embedding the software engineering process in business process optimization projects and by closely involving end users to improve their own work practices. METHODS: We have used a holistic health information system as a core application framework. System functionality is incrementally improved using an integrated "generator tool" for rapid application development. We have developed an iterative and participatory software engineering process, adapted to the conditions of the generator tool. The documentation techniques provided by the Unified Modeling Language (UML) were modified to achieve a straight forward documentation covering the whole development cycle from the business process model to generator-based computer applications. RESULTS AND CONCLUSION: The layered approach for system evolution did provide an environment in which a flexible and participatory software development process could be established. Today, generator-based applications are used in all clinical departments of our 1200-bed University Hospital. We expect that tools for rapid application development will be further improved and will play an increasingly important role to establish responsive IT-infrastructures where the application developer can concentrate on business process alignment instead of coding and debugging.

Toward personal eHealth in cardiology. Results from the EPI-MEDICS telemedicine project.

Despite many attempts to improve the management of acute myocardial infarction, only small trends to shorter time intervals before treatment have been reported. The self-care solution developed by the European EPI-MEDICS project (2001-2004) is a novel, very affordable, easy-to-use, portable, and intelligent Personal ECG Monitor (PEM) for the early detection of cardiac ischemia and arrhythmia that is able to record a professional-quality, 3-lead electrocardiogram (ECG) based on leads I, II, and V2; derive the missing leads of the standard 12-lead ECG (thanks to either a generic or a patient-specific transform), compare each ECG with a reference ECG by means of advanced neural network-based decision-making methods taking into account the serial ECG measurements and the patient risk factors and clinical data; and generate different levels of alarms and forward the alarm messages with the recorded ECGs and the patient's Personal electronic Health Record (PHR) to the relevant health care providers by means of a standard Bluetooth-enabled, GSM/GPRS-compatible mobile phone. The ECG records are SCP-ECG encoded and stored with the PHR on a secure personal SD Card embedded in the PEM device. The alarm messages and the PHR are XML encoded. Major alarm messages are automatically transmitted to the nearest emergency call center. Medium or minor alarms are sent on demand to a central PEM Alarm Web Server. Health professionals are informed by a Short Message Service. The PEM embeds itself a Web server to facilitate the reviewing and/or update of the PHR during a routine visit at the office of the general physician or cardiologist. Eighty PEM prototypes have been finalized and tested for several weeks on 697 citizens/patients in different clinical and self-care situations involving end users (188 patients), general physicians (10), and cardiologists (9). The clinical evaluation indicates that the EPI-MEDICS concept may save lives and is very valuable for prehospitalization triage.

Methods of multidisciplinary in-depth analyses of road traffic accidents.

A multidisciplinary Road Accident Analysis Group with the objective of conducting in-depth investigations of specific types of accidents has existed in Denmark for some years. The group has analysed head-on collisions, left-turn accidents, truck accidents and single vehicle accidents. The data collection included police reports, the group's investigation of accident sites and vehicles involved, and interviews with the involved road users and witnesses. The main accident factors in the head-on collisions and in the single vehicle accidents were excessive speed, drunk driving and driving under the influence of illegal drugs. The primary accident factors in left-turn accidents were attention errors or misjudging the amount of time available to complete the left turn. In the truck accidents insufficient searching for visual information as well as speeding were major factors. For all the accident themes the primary injury factor was failure to wear seat- belts. The multidisciplinary approach has provided a rather precise knowledge of the contributing factors leading up to the accident. The method requires a lot of resources, which is a limiting factor for the number of accidents to be analysed in this way. However, the method is suitable for analysis of common occurring or very serious types of accidents.

Do we have a knowledge transfer and translation plan at Teratogen Information Services?

Recently, a new field in science is emerging, which addresses the issue of ensuring that information that is generated from research, reaches the right people in the right format. This has been coined as knowledge transfer and translation and public health leaders worldwide are finding out ways to carry this out effectively. Ultimately, this should ensure greater investment in knowledge syntheses and transfer initiatives, that involve potential users of research to improve the quality of health for everyone. In this brief review/comment, an attempt will be made to help the readers understand the meaning of this new terminology and how it impacts Teratogen Information Services.

A naturalistic inquiry on the impact of interventions aiming to improve health and the quality of life in the community.

The goal of this study is to identify and describe variables contributing to the efficiency of health promotion interventions, and to assess whether these variables can serve as reliable and early indicators of the success of such interventions. The study sample includes 44 interventions selected through a network of key informants from five cities--Liverpool, Sandwell, Vienna, Pula, and Rijeka--by using a chain technique. Data on each intervention are collected through an in-depth interview with a program leader, the collection of project-related documents, and on-site observation. Qualitative analysis of data performed with content analysis and computer-assisted free-text analysis reveals different characteristics of interventions depending on whether they are initiated by the city government sector, health-care system, or citizens sector (independent of the city or country). The assessment of the efficiency of these three groups of interventions also differs because of varying features, scope (activity potentials) and impact they are able to accomplish. We have identified ways in which the efficiency of all three groups of interventions can be improved. The efficiency of the interventions within the city sector can be increased through an improved process of delegation to other sectors, higher involvement of user groups, and higher receptivity and organizational flexibility. The efficiency of the interventions within the citizens sector can be improved through professional, organizational, and financial support. Support from the professional community is important for citizens sector interventions in confirming the importance of the problem they address and legitimizing the actions they propose and undertake.

Multidisciplinary in-depth investigations of head-on and left-turn road collisions.

To enhance traffic safety, a multidisciplinary Road Accident Investigation Team was established in Denmark for a 2-year trial period. The objective was to conduct in-depth investigations of specific types of accidents, and to identify effective preventive measures. The team consisted of a road engineer, a vehicle inspector, a police superintendent, a psychologist and a physician. Seventeen serious head-on collisions as well as 17 left-turn collisions were analysed. In collecting data, police reports were supplemented by the team's investigation of accident sites and vehicles involved, and interviews were carried out with the involved road users and witnesses. The drivers, to whom the accident factors were primarily related in the head-on collisions, were characterised by their conscious risk-taking behaviour. They were all males; several of them were under age 40 and had earlier traffic and/or drug convictions. The main accident factors were excessive speed, drunk driving and driving under the influence of illegal drugs. In the left-turn accidents, the most common accident factors were attention errors, and it was also noted that elderly drivers ( > 74) were over-represented. The synergy effect of working as a multidisciplinary team proved fruitful. It resulted in a more precise knowledge of the road accident circumstances and of contributing factors leading up to the accidents. Due to the great demand on resources, only a limited number of accidents could be analysed, but the results provide a basis for further and more targeted research.

Incorporating patients' views and experiences of life with IBS in the development of an evidence based self-help guidebook.

To become active partners in chronic illness management, patients need relevant information which clearly explains treatment choices. This paper describes a method of producing information to feed into production of a guidebook for people with irritable bowel syndrome (IBS). Users were involved throughout the development process. Five focus groups were held involving 23 people with IBS out of 147 who responded to a newspaper article asking for help with a study of self-care in IBS. Qualitative analysis of transcripts from these meetings formed the basis of guidebook development. Patients described their experiences, coping strategies, experiences of the healthcare system, treatments and social consequences of the condition. Medical literature searches were made to find answers to identified areas of information need. The book includes direct quotes from patients describing their own experiences. Guided and practical ways of support are required for people with IBS who want to self-manage their condition.

Productivity associated with visual status of computer users.

BACKGROUND: The aim of this project is to examine the potential connection between the astigmatic refractive corrections of subjects using computers and their productivity and comfort. We hypothesize that improving the visual status of subjects using computers results in greater productivity, as well as improved visual comfort. METHODS: Inclusion criteria required subjects 19 to 30 years of age with complete vision examinations before being enrolled. Using a double-masked, placebo-controlled, randomized design, subjects completed three experimental tasks calculated to assess the effects of refractive error on productivity (time to completion and the number of errors) at a computer. The tasks resembled those commonly undertaken by computer users and involved visual search tasks of: (1) counties and populations; (2) nonsense word search; and (3) a modified text-editing task. RESULTS: Estimates of productivity for time to completion varied from a minimum of 2.5% upwards to 28.7% with 2 D cylinder miscorrection. Assuming a conservative estimate of an overall 2.5% increase in productivity with appropriate astigmatic refractive correction, our data suggest a favorable cost-benefit ratio of at least 2.3 for the visual correction of an employee (total cost 268 dollars) with a salary of 25,000 dollars per year. CONCLUSIONS: We conclude that astigmatic refractive error affected both productivity and visual comfort under the conditions of this experiment. These data also suggest a favorable cost-benefit ratio for employers who provide computer-specific eyewear to their employees.

Development and evaluation of intermediate care.

Intermediate care is being developed as part of the national strategy for older people in England and Wales to prevent their admission to hospital and facilitate early discharge. Evaluation of intermediate care is implicit within current policy directives. This project evaluated the client information across a number of intermediate care schemes within one National Health Service community trust for 3 months and disseminated the results to staff as part of a reflective workshop which also provided an opportunity for additional data collection. Rates of referral and acceptance on intermediate care were high for all the schemes except one, indicating reliable referral and inclusion criteria. Older people were the recipients of intermediate care with nearly half of them having experienced falls. A number of developments were identified by staff covering both current services and long-term strategy for intermediate care and indicating the importance of involving providers in the evaluation and development of services. Fall prevention initiatives and involvement of users and carers in the evaluation and development of intermediate care were also identified.

The national continuous quality improvement tool for mental health education: results of targeted and supported implementation in England.

The national continuous quality assurance tool for mental health education and training has recently been developed. This paper describes the planned implementation of the tool across NHS Workforce Development Confederations (WDCs) in England. Large stakeholder groups in 15 WDCS were convened. The groups rated 29 programmes across a range of provisions including pre-qualifying programmes (social work and mental health nursing), post-qualifying programmes, new graduate mental health worker programmes and programmes run within NHS Trusts. Overall, the results indicate that the majority of rated programmes are relevant to the policy agenda and involve service users in a meaningful way. However, courses are less likely to engage with carers and to assess the impact of the programmes. Key factors are identified that promote the implementation of the new quality assurance tool and key barriers to implementation are also elicited. The paper concludes that the tool can provide a useful framework to assess the quality of a broad range of mental health education, furthermore, that it should be incorporated into existing quality assurance systems.

Criminal involvement among young male ecstasy users.

Ecstasy (MDMA) use increased rapidly in the U.S. between about 1995 and 2001. Most research on the drug focused on its psychopharmacological and public health contexts. Previous research on drugs-crime linkages suggests that there may have been a concommitant rise in ecstasy-related crimes. We explore this dimension here using data from 7794 arrested men, age 16 to 25, in the 2001 Arrestee Drug Abuse Monitoring (ADAM) sample and 9764 male respondents of similar age in the 2001 National Household Survey on Drug Abuse (NHSDA). Our results using a variety of bivariate and regression methods indicate that ecstasy use is less prevalent among young male arrestees than young men in general and that ecstasy use among arrestees is positively associated with various measures of drug market participation but negatively related to violent and property offenses. We recommend further investigation of ecstasy use in drug-oriented data sets and longitudinal studies to evaluate the link between ecstasy use and overall drug marketing.

Demographics and patterns of acupuncture use in the Chinese population: the Taiwan experience.

BACKGROUND: The use of complementary and alternative medicine (CAM), including Traditional Chinese Medicine (TCM) and acupuncture, has substantially increased in western countries in the past decade. However, informative data concerning large-scale investigations of acupuncture used in the Chinese society remain rare so far. DESIGN AND OUTCOME MEASURE: The complete datasets of acupuncture outpatient reimbursement claims from 1996 to 2002 were supplied by the National Health Insurance Research Database, Taiwan, and the usage frequencies and characteristics of the acupuncture users, as well as the disease categories that were treated by acupuncture in Taiwan were analyzed. RESULTS: At the end of 2002, among the 21,869,478 total valid beneficiaries of National Health Insurance (NHI), 1,362,351 subjects (6.2%) used acupuncture during this year, but 4,948,464 subjects (22.6%) had used it for the whole 7-year period since 1996. A mean increment of 1,191,164 (53.6%) new users had been involved yearly. Among all those acupuncture users, a female predominance was observed (female:male = 1.12:1), and the age distribution displayed a peak at around the 40s, followed by the 30s and 50s. Private TCM clinics provided more acupuncture usage (82.0%) than did private TCM hospitals (13.7%). The disease categories treated mostly by acupuncture were diseases of the musculoskeletal system (46.2%); injury (41.8%); diseases of the nervous system (3.5%); and symptoms, signs, and ill-defined conditions (2.7%). CONCLUSIONS: Twenty-three percent (23%) of people in Taiwan had used acupuncture during this 7-year period. Musculoskeletoal and neurologic disorders were two major categories commonly treated with acupuncture.
