Pathways to evidence-based reproductive healthcare in developing countries.

OBJECTIVE: Developing country clinicians are aware of the discourse of evidence-based medicine but heavily constrained in their ability to access and apply new knowledge. This study aimed to obtain primary descriptive data about access to and application of reproductive health-related medical knowledge in developing countries. DESIGN: Qualitative study using semi-structured interviews. SETTING: India and Yemen. SAMPLE: Forty-one doctors working in obstetrics, gynaecology, general practice and family planning services. METHODS: Interviews were tape recorded and transcribed verbatim. A theory-driven approach was conducted to carry out thematic analysis. MAIN OUTCOME MEASURES: Descriptions of experiences, attitudes and needs. RESULTS: Doctors felt the need to update their knowledge but this was not always achieved due to time and financial constraints. Alternative knowledge sources were described including the Internet, scientific meetings, medical family networks and speciality medical societies but access to these was limited by the expense of equipment, unfamiliarity with the technology and restricted advertisement of scientific meetings and conferences. Institutional hierarchy and conflict of generations were identified as barriers to change. Demoralisation was a common obstacle. On the positive side, involvement in medical education was a powerful driver for seeking new knowledge and applying research evidence to clinical practice. CONCLUSIONS: Priorities are to identify needs specific to different countries and medical settings in the developing world, access for all to full text journals and educational activities that fully engage practitioners in the early stages of their careers. Clinical teachers are the nodal group with the strongest incentive to obtain and use new knowledge.

From public health to population health: epidemiological yardsticks for perinatal care.

Perinatal epidemiology and health services research have focused on specific health outcomes or disease states ("key" indicators and/or sentinel events), clients of public programs, and clinical service populations. In this paper, the concept of "population health" is defined and operationalized for the broad perinatal healthcare context within the framework of population health informatics. Traditional indicators and outcome measures for perinatal health are compared with some newer measures and assessed for their relevance to population health. A hypothetical model for the implementation of population health informatics for maternal and child health is described; in addition, and some obstacles to the practice of population health are identified, with strategies to overcome these obstacles.

Some methods for blindfolded record linkage.

BACKGROUND: The linkage of records which refer to the same entity in separate data collections is a common requirement in public health and biomedical research. Traditionally, record linkage techniques have required that all the identifying data in which links are sought be revealed to at least one party, often a third party. This necessarily invades personal privacy and requires complete trust in the intentions of that party and their ability to maintain security and confidentiality. Dusserre, Quantin, Bouzelat and colleagues have demonstrated that it is possible to use secure one-way hash transformations to carry out follow-up epidemiological studies without any party having to reveal identifying information about any of the subjects - a technique which we refer to as "blindfolded record linkage". A limitation of their method is that only exact comparisons of values are possible, although phonetic encoding of names and other strings can be used to allow for some types of typographical variation and data errors. METHODS: A method is described which permits the calculation of a general similarity measure, the n-gram score, without having to reveal the data being compared, albeit at some cost in computation and data communication. This method can be combined with public key cryptography and automatic estimation of linkage model parameters to create an overall system for blindfolded record linkage. RESULTS: The system described offers good protection against misdeeds or security failures by any one party, but remains vulnerable to collusion between or simultaneous compromise of two or more parties involved in the linkage operation. In order to reduce the likelihood of this, the use of last-minute allocation of tasks to substitutable servers is proposed. Proof-of-concept computer programmes written in the Python programming language are provided to illustrate the similarity comparison protocol. CONCLUSION: Although the protocols described in this paper are not unconditionally secure, they do suggest the feasibility, with the aid of modern cryptographic techniques and high speed communication networks, of a general purpose probabilistic record linkage system which permits record linkage studies to be carried out with negligible risk of invasion of personal privacy.

[Education in public health in Mauritius. Presentation of an experience].

In December 1991, fourteen physicians in the public sector received a degree entitled "Methods in public health", awarded by the dean of Université de Bordeaux II (France) and the Mauritius minister of health. The ceremony crowned a two-year course consisting of 350 hours of lectures and other teaching exercises, broken down into 12 subject areas (epidemiology, biostatistics, medical informatics, demographics, health care, planning, health economics, etc.). The graduates did an average of 10 year's field work in a primary health care center. The degree was awarded after completion of a mini-thesis based on an original study of a selected Mauritian public health problem. In 1992 and 1993, a new, shorter course in community health was offered to other Mauritian physicians by staff from Université de Bordeaux II. We consider that such initiatives would be profitable in other countries like Mauritius, where commonly encountered health care problems of the developing countries coexist with those found in the industrialized world. This will also be an important initiative in countries where initial training in various contexts and therefore can benefit from a common continuing medical education, particularly in public health. One key factor in the success of such projects is their full integration within the medical sciences.

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.

Secure communication and co-operation of distributed Electronic Patient Records.

Electronic Health Records (EHR) are moving towards the core application of health information systems. Enabling informational interoperability of shared care environment including EHR, structure and function of components used have to follow open standards and publicly available specifications. This comprises also methods and tools applied. Security services needed have to be an integral part of architecture and operation of the specified and implemented components. Starting with basic architectural paradigms the Magdeburg Medical Informatics Department was involved in at the early nineties, the secure behaviour of components has been derived. For establishing the required trustworthiness, security models have been introduced and presented in the paper. Beside communication security services based on standardised Public Key Infrastructure (PKI) and security token such as Health Professional Cards (HPC), policy-defined application security services such as authorisation, access control, accountability, etc., of information recorded, stored and processed must be guaranteed. In that context, appropriate resource access decision services have to be established. As the HARP project result, a component-based EHR architecture has been specified and demonstrated for enforcing fine-grained security services by binding certificates to application components, by the way enforcing policies.

Health informatics: ethical issues.

Ethics is a component of the education of health care mangers and supervisors. Recent advances in the technologies of health informatics present these leader with new ethical challenges. Holding the promise of beneficence, these technologies are purported to increase access, improve quality, and decrease the costs of care. Aspects of these technologies, however, create conflicts with the ethical principles of autonomy, fidelity, and justice. Infoethics is suggested as a means to examine these conflicts. A multipronged solution that incorporates adherence to regulations and standards, promotion of codes of conduct and ethics, and creation of a culture of infoethics is recommended.

FDA regulation of medical software.

Currently the FDA is reviewing its policy on the regulation of computer software in the medical arena. Healthcare practitioners hope that the FDA will take the least possible regulatory action required by law to fulfill its public health responsibility and will take into account the unique status of the ever-changing software industry. Innovations in telemedicine and medical informatics have yielded significant improvements in the quality and cost of healthcare, and the imposition of cumbersome regulatory requirements on the medical software industry would slow the development and introduction of medical software products.

"Is Cybermedicine Killing You?"--The story of a Cochrane disaster.

This editorial briefly reviews the series of unfortunate events that led to the publication, dissemination, and eventual retraction of a flawed Cochrane systematic review on interactive health communication applications (IHCAs), which was widely reported in the media with headlines such as "Internet Makes Us Sick," "Knowledge May Be Hazardous to Web Consumers' Health," "Too Much Advice Can Be Bad for Your Health," "Click to Get Sick?," and even "Is Cybermedicine Killing You?". While the media attention helped to speed up the identification of errors, leading to a retraction of the review after only 13 days, a paper published in this issue of JMIR by Rada shows that the retraction, in contrast to the original review, remained largely unnoticed by the public. We discuss the three flaws of the review, which include (1) data extraction and coding errors, (2) the pooling of heterogeneous studies, and (3) a problematic and ambiguous scope and, possibly, some overlooked studies. We then discuss "retraction ethics" for researchers, editors/publishers, and journalists. Researchers and editors should, in the case of retractions, match the aggressiveness of the original dissemination campaign if errors are detected. It is argued that researchers and their organizations may have an ethical obligation to track down journalists who reported stories on the basis of a flawed study and to specifically ask them to publish an article indicating the error. Journalists should respond to errors or retractions with reports that have the same prominence as the original story. Finally, we look at some of the lessons for the Cochrane Collaboration, which include (1) improving the peer-review system by routinely sending out pre-prints to authors of the original studies, (2) avoiding downplay of the magnitude of errors if they occur, (3) addressing the usability issues of RevMan, and (4) making critical articles such as retraction notices open access.

Summary recommendations for responsible monitoring and regulation of clinical software systems. American Medical Informatics Association, The Computer-based Patient Record Institute, The Medical Library Association, The Association of Academic Health Science Libraries, The American Health Information Management Association, and The American Nurses Association.

Clinical software systems are becoming ubiquitous. A growing literature documents how these systems can improve health care delivery, but concerns about patient safety must now be formally addressed. In 1996, the U.S. Food and Drug Administration (FDA) called for discussions on regulation of software programs as medical devices. In response, a consortium of organizations dedicated to improving health care through information technology developed recommendations for the responsible regulation and monitoring of clinical software systems by users, vendors, and regulatory agencies. These recommendations were revised and approved by the American Medical informatics Association Public Policy Committee and Board. Other organizations reviewed, modified, and approved the recommendations, and the Boards of Directors of most of the organizations in the consortium endorsed the guidelines. The consortium proposes four categories of clinical system risk and four classes of monitoring and regulatory action that can be applied on the basis of the risk level. The consortium recommends that most clinical software systems be supervised locally and that developers of health care information systems adopt a code of good business practices. Budgetary and other constraints limit the type and number of systems that the FDA can regulate effectively; therefore, the FDA should exempt most clinical software systems and focus on systems that pose high clinical risk and provide limited opportunity for competent human intervention.

The informatics response in disaster, terrorism, and war.

The United States currently faces several new, concurrent large-scale health crises as a result of terrorist activity. In particular, three major health issues have risen sharply in urgency and public consciousness--bioterrorism, the threat of widespread delivery of agents of illness; mass disasters, local events that produce large numbers of casualties and overwhelm the usual capacity of health care delivery systems; and the delivery of optimal health care to remote military field sites. Each of these health issues carries large demands for the collection, analysis, coordination, and distribution of health information. The authors present overviews of these areas and discuss ongoing work efforts of experts in each.

Health care consumers' experiences of information communication technology--a summary of literature.

BACKGROUND: There is an increasing interest in reaching consumers directly through the Internet and different telecommunication systems. The most important contacts in health care will always be the face-to-face meetings, but the tools of health informatics can be seen as a means to an end, which is to provide the best possible health care. A variety of applications have been described in different references. To our knowledge there has been no review of a research-based state of the art in the field of consumers' experiences in using different applications in health informatics. According to the benefits in using information communication technology (ICT) as being cost-effective and timesaving it is of great importance to focus on and examine consumers' experiences. It is important that it is user friendly and regarded as valuable and useful. AIM: The aim of this study was to describe consumers' subjective experiences of using electronic resources with reference to health and illness. DESIGN AND/OR METHOD: A systematic literature search was performed in databases CINAHL, Medline and Cochrane, as well as a manual search. Retrieved references (n=14) were appraised according to their scientific structure and quality. A broad search was performed in order to find as many different applications as possible. Our primary intention was to identify existing references describing consumers' experiences with ICT. RESULTS: In spite of this broad search few references were found. Twelve references remained and three themes were identified: support and help, education and information, and telecommunication instead of on-site visiting. Consumers felt more confident and empowered, their knowledge increased and their health status improved due to the ICT resources. Lack of face-to-face meetings or privacy did not appear to be a problem. CONCLUSION: ICT can improve the nurse-patient relationship and augment well-being for consumers. More research is needed to measure consumers' experiences and factors that influence it.

[Founding and development of the Croatian Health Information System].

Information systems, either computer or paper based, are the key to business effectiveness and efficiency of healthcare organizations. The rationale of starting a large healthcare informatics project by the Ministry of Health and Welfare may be argued by two needs: (1) the need of medical data transformation into the information required for public health policy decision-making; and (2) measures in the field of health and pharmacoeconomics, i.e. systematic surveillance of healthcare costs that define the prospects for savings without lowering the level of service (estimated at 20%-30% of potential savings), along with the need of transparency and adoption of European Union directives and standards. Implementation of the proposed system results in two groups of fundamental functions: (1) the creation of a central public health information system which facilitates real-time tracking of primary healthcare cost generators, which in turn are used for creating health economics policy, and (2) to automatize the process of generating a consolidated national health budget including the Croatian Institute of Health Insurance and hospitals as well as consolidated financial reports for all those involved in the healthcare system. The model of the National Health Information System of the Republic of Croatia is described.

Toward a national framework for the secondary use of health data: an American Medical Informatics Association White Paper.

Secondary use of health data applies personal health information (PHI) for uses outside of direct health care delivery. It includes such activities as analysis, research, quality and safety measurement, public health, payment, provider certification or accreditation, marketing, and other business applications, including strictly commercial activities. Secondary use of health data can enhance health care experiences for individuals, expand knowledge about disease and appropriate treatments, strengthen understanding about effectiveness and efficiency of health care systems, support public health and security goals, and aid businesses in meeting customers' needs. Yet, complex ethical, political, technical, and social issues surround the secondary use of health data. While not new, these issues play increasingly critical and complex roles given current public and private sector activities not only expanding health data volume, but also improving access to data. Lack of coherent policies and standard "good practices" for secondary use of health data impedes efforts to strengthen the U.S. health care system. The nation requires a framework for the secondary use of health data with a robust infrastructure of policies, standards, and best practices. Such a framework can guide and facilitate widespread collection, storage, aggregation, linkage, and transmission of health data. The framework will provide appropriate protections for legitimate secondary use.

Building the national health information infrastructure for personal health, health care services, public health, and research.

BACKGROUND: Improving health in our nation requires strengthening four major domains of the health care system: personal health management, health care delivery, public health, and health-related research. Many avoidable shortcomings in the health sector that result in poor quality are due to inaccessible data, information, and knowledge. A national health information infrastructure (NHII) offers the connectivity and knowledge management essential to correct these shortcomings. Better health and a better health system are within our reach. DISCUSSION: A national health information infrastructure for the United States should address the needs of personal health management, health care delivery, public health, and research. It should also address relevant global dimensions (e.g., standards for sharing data and knowledge across national boundaries). The public and private sectors will need to collaborate to build a robust national health information infrastructure, essentially a 'paperless' health care system, for the United States. The federal government should assume leadership for assuring a national health information infrastructure as recommended by the National Committee on Vital and Health Statistics and the President's Information Technology Advisory Committee. Progress is needed in the areas of funding, incentives, standards, and continued refinement of a privacy (i.e., confidentiality and security) framework to facilitate personal identification for health purposes. Particular attention should be paid to NHII leadership and change management challenges. SUMMARY: A national health information infrastructure is a necessary step for improved health in the U.S. It will require a concerted, collaborative effort by both public and private sectors.
