Improving Information and Communications Technology (ICT) Knowledge and Skills to Develop Health Research Capacity in Kenya.

Objectives Information and communication technology (ICT) tools are increasingly important for clinical care and international research. Many technologies would be particularly useful for healthcare workers in resource-limited settings; however, these individuals are the least likely to utilize ICT tools due tolack of knowledge and skills necessary to use them. Our program aimed to train researchers in low-resource settings on using ICT tools and to understand how different didactic modalities build knowledge and skills in this area. Methods We conducted a tiered, blended learning program for researchers in Kenya on three areas of ICT: geographic information systems, data management, and communication tools. Each course included three tiers: online courses, skills workshops, and mentored projects. Concurrently, a training of trainers course was taught to ensure sustainable ongoing training. A mixed qualitative and quantitative survey was conducted at the end of each training to assess knowledge and skill acquisition. Results Course elements that incorporated local examples and hands-on skill building activities were most valuable. Discussion boards were sometimes distracting, depending on multiple factors. Mentored projects were most useful when there were clear expectations, pre-existing projects, and clear timelines. Discussion Training in the use of ICT tools is highly valued among researchers in low-income settings, particularly when it includes hands-on skill-building and local examples. Our students demonstrated acquisition of new skills and felt these skills to be valuable in their workplaces. Conclusions Further training in ICT skills should be considered in other low-resource settings using our program as a foundational model.

Patient-Held Maternal and/or Child Health Records: Meeting the Information Needs of Patients and Healthcare Providers in Developing Countries?

Though improvements in infant and maternal mortality rates have occurred over time, women and children still die every hour from preventable causes. Various regional, social and economic factors are involved in the ability of women and children to receive adequate care and prevention services. Patient-held maternal and/or child health records have been used for a number of years in many countries to help track health risks, vaccinations and other preventative health measures performed. Though these records are primarily designed to record patient histories and healthcare information and guide healthcare workers providing care, because the records are patient-held, they also allow families a greater ability to track their own health and prevention strategies. A LITERATURE SEARCH WAS PERFORMED TO ANSWER THESE QUESTIONS: (1) What are maternal information needs regarding pregnancy, post-natal and infant healthcare, especially in developing countries? (2) What is known about maternal information seeking behavior in developing countries? (3) What is the history and current state of maternal and/or child patient-held healthcare records, do they provide for the information needs of the healthcare provider and what are the effects and outcomes of patient-held records in general and for maternal and/or child health in particular? Specific information needs of pregnant women and mothers are rarely studied. The small numbers of maternal information behavior results available indicate that mothers, in general, prefer to receive health information directly from their healthcare provider as opposed to from other sources (written, etc.) Overall, in developing countries, patient-held maternal and/or child healthcare records have a mostly positive effect for both patient and care provider. Mothers and children with records tend to have better outcomes in healthcare and preventative measures. Further research into the information behaviors of pregnant women and mothers to determine the extent of reliance on interpersonal information seeking is recommended before expending significant resources on enhanced patient-held maternal and/or child healthcare records including storage on mobile devices. In particular, research is needed to explore the utility of providing targeted health messages to mothers regarding their own health and that of their children; this might best be accomplished through mobile technologies.

Ten years of international collaboration in biomedical informatics and beyond: the AMAUTA program in Peru.

Well-trained people are urgently needed to tackle global health challenges through information and communication technologies. In this report, AMAUTA, a joint international collaborative training program between the Universidad Peruana Cayetano Heredia and the University of Washington, which has been training Peruvian health professionals in biomedical and health informatics since 1999, is described. Four short-term courses have been organized in Lima, offering training to more than 200 graduate-level students. Long-term training to masters or doctorate level has been undertaken by eight students at the University of Washington. A combination of short-term and long-term strategies was found to be effective for enhancing institutional research and training enterprise. The AMAUTA program promoted the development and institution of informatics research and training capacity in Peru, and has resulted in a group of trained people playing important roles at universities, non-government offices, and the Ministry of Health in Peru. At present, the hub is being extended into Latin American countries, promoting South-to-South collaborations.

Developing capacity in health informatics in a resource poor setting: lessons from Peru.

The public sectors of developing countries require strengthened capacity in health informatics. In Peru, where formal university graduate degrees in biomedical and health informatics were lacking until recently, the AMAUTA Global Informatics Research and Training Program has provided research and training for health professionals in the region since 1999. The Fogarty International Center supports the program as a collaborative partnership between Universidad Peruana Cayetano Heredia in Peru and the University of Washington in the United States of America. The program aims to train core professionals in health informatics and to strengthen the health information resource capabilities and accessibility in Peru. The program has achieved considerable success in the development and institutionalization of informatics research and training programs in Peru. Projects supported by this program are leading to the development of sustainable training opportunities for informatics and eight of ten Peruvian fellows trained at the University of Washington are now developing informatics programs and an information infrastructure in Peru. In 2007, Universidad Peruana Cayetano Heredia started offering the first graduate diploma program in biomedical informatics in Peru.

Integrating open-source technologies to build low-cost information systems for improved access to public health data.

Effective public health practice relies on the availability of public health data sources and assessment tools to convey information to investigators, practitioners, policy makers, and the general public. Emerging communication technologies on the Internet can deliver all components of the "who, what, when, and where" quartet more quickly than ever with a potentially higher level of quality and assurance, using new analysis and visualization tools. Open-source software provides the opportunity to build low-cost information systems allowing health departments with modest resources access to modern data analysis and visualization tools. In this paper, we integrate open-source technologies and public health data to create a web information system which is accessible to a wide audience through the Internet. Our web application, "EpiVue," was tested using two public health datasets from the Washington State Cancer Registry and Washington State Center for Health Statistics. A third dataset shows the extensibility and scalability of EpiVue in displaying gender-based longevity statistics over a twenty-year interval for 3,143 United States counties. In addition to providing an integrated visualization framework, EpiVue's highly interactive web environment empowers users by allowing them to upload their own geospatial public health data in either comma-separated text files or MS Excel spreadsheet files and visualize the geospatial datasets with Google Maps.

Time-tradeoff utilities for identifying and evaluating a minimum data set for time-critical biosurveillance.

BACKGROUND: Researchers and policy makers are interested in identifying, implementing, and evaluating a national minimum data set for biosurveillance. However, work remains to be done to establish methods for measuring the value of such data. PURPOSE: The purpose of this article is to establish and evaluate a method for measuring the utility of biosurveillance data. METHOD: The authors derive an expected utility model in which the value of data may be determined by trading data relevance for time delay in receiving data. In a sample of 23 disease surveillance practitioners, the authors test if such tradeoffs are sensitive to the types of data elements involved (chief complaint v. emergency department [ED] log of visit) and proportional changes to the time horizon needed for receiving data (24 v. 48 h). In addition, they evaluate the logical error rate: the proportion of responses that scored less relevant data as having higher utility. RESULTS: Utilities of chief complaints were significantly higher than ED log of visit, F(1, 21)= 5.60, P < 0.05, suggesting the method is sensitive. Further utilities did not depend on time horizon used in the exercise, F(1, 21) = 0.00, P = ns. Of 92 time tradeoffs elicited, there were 5 logical errors (i.e., 5% logical error rate). CONCLUSIONS: In this article, the authors establish a time-tradeoff exercise for valuing biosurveillance data. Empirically, the method shows initial promise for evaluating a minimum data set for biosurveillance. Future applications of this approach may prove useful in disease surveillance planning and evaluation.

Evaluation of a joint Bioinformatics and Medical Informatics international course in Peru.

BACKGROUND: New technologies that emerge at the interface of computational and biomedical science could drive new advances in global health, therefore more training in technology is needed among health care workers. To assess the potential for informatics training using an approach designed to foster interaction at this interface, the University of Washington and the Universidad Peruana Cayetano Heredia developed and assessed a one-week course that included a new Bioinformatics (BIO) track along with an established Medical/Public Health Informatics track (MI) for participants in Peru. METHODS: We assessed the background of the participants, and measured the knowledge gained by track-specific (MI or BIO) 30-minute pre- and post-tests. Participants' attitudes were evaluated both by daily evaluations and by an end-course evaluation. RESULTS: Forty-three participants enrolled in the course - 20 in the MI track and 23 in the BIO track. Of 20 questions, the mean % score for the MI track increased from 49.7 pre-test (standard deviation or SD = 17.0) to 59.7 (SD = 15.2) for the post-test (P = 0.002, n = 18). The BIO track mean score increased from 33.6 pre-test to 51.2 post-test (P < 0.001, n = 21). Most comments (76%) about any aspect of the course were positive. The main perceived strength of the course was the quality of the speakers, and the main perceived weakness was the short duration of the course. Overall, the course acceptability was very good to excellent with a rating of 4.1 (scale 1-5), and the usefulness of the course was rated as very good. Most participants (62.9%) expressed a positive opinion about having had the BIO and MI tracks come together for some of the lectures. CONCLUSION: Pre- and post-test results and the positive evaluations by the participants indicate that this first joint Bioinformatics and Medical/Public Health Informatics (MI and BIO) course was a success.

Issues in biomedical research data management and analysis: needs and barriers.

OBJECTIVES: A. Identify the current state of data management needs of academic biomedical researchers. B. Explore their anticipated data management and analysis needs. C. Identify barriers to addressing those needs. DESIGN: A multimodal needs analysis was conducted using a combination of an online survey and in-depth one-on-one semi-structured interviews. Subjects were recruited via an e-mail list representing a wide range of academic biomedical researchers in the Pacific Northwest. MEASUREMENTS: The results from 286 survey respondents were used to provide triangulation of the qualitative analysis of data gathered from 15 semi-structured in-depth interviews. RESULTS: Three major themes were identified: 1) there continues to be widespread use of basic general-purpose applications for core data management; 2) there is broad perceived need for additional support in managing and analyzing large datasets; and 3) the barriers to acquiring currently available tools are most commonly related to financial burdens on small labs and unmet expectations of institutional support. CONCLUSION: Themes identified in this study suggest that at least some common data management needs will best be served by improving access to basic level tools such that researchers can solve their own problems. Additionally, institutions and informaticians should focus on three components: 1) facilitate and encourage the use of modern data exchange models and standards, enabling researchers to leverage a common layer of interoperability and analysis; 2) improve the ability of researchers to maintain provenance of data and models as they evolve over time though tools and the leveraging of standards; and 3) develop and support information management service cores that could assist in these previous components while providing researchers with unique data analysis and information design support within a spectrum of informatics capabilities.

Understanding the information needs of public health practitioners: a literature review to inform design of an interactive digital knowledge management system.

UNLABELLED: The need for rapid access to information to support critical decisions in public health cannot be disputed; however, development of such systems requires an understanding of the actual information needs of public health professionals. This paper reports the results of a literature review focused on the information needs of public health professionals. The authors reviewed the public health literature to answer the following questions: (1) What are the information needs of public health professionals? (2) In what ways are those needs being met? (3) What are the barriers to meeting those needs? (4) What is the role of the Internet in meeting information needs? The review was undertaken in order to develop system requirements to inform the design and development of an interactive digital knowledge management system. The goal of the system is to support the collection, management, and retrieval of public health documents, data, learning objects, and tools. METHOD: The search method extended beyond traditional information resources, such as bibliographic databases, tables of contents (TOC), and bibliographies, to include information resources public health practitioners routinely use or have need to use--for example, grey literature, government reports, Internet-based publications, and meeting abstracts. RESULTS: Although few formal studies of information needs and information-seeking behaviors of public health professionals have been reported, the literature consistently indicated a critical need for comprehensive, coordinated, and accessible information to meet the needs of the public health workforce. Major barriers to information access include time, resource reliability, trustworthiness/credibility of information, and "information overload". CONCLUSIONS: Utilizing a novel search method that included the diversity of information resources public health practitioners use, has produced a richer and more useful picture of the information needs of the public health workforce than other literature reviews. There is a critical need for public health digital knowledge management systems designed to reflect the diversity of public health activities, to enable human communications, and to provide multiple access points to critical information resources. Public health librarians and other information specialists can serve a significant role in helping public health professionals meet their information needs through the development of evidence-based decision support systems, human-mediated expert searching and training in the use information retrieval systems.

Training biomedical and health informatics professionals in Peru: towards the development of the first graduate diploma program in the country.

In Peru, there are no formal university graduate programs in biomedical and health informatics, and there is a lack of other health informatics programs. AMAUTA, a joint program between the Universidad Peruana Cayetano Heredia (UPCH) in Lima and the University of Washington (UW) in Seattle has been training Peruvian health professionals since 1999 regarding biomedical and health informatics. In 2007, UPCH is offering the first Graduate Diploma Program in Biomedical Informatics in the country.

Towards automatic extraction of research findings from the literature.

Most information extraction systems only process an article's title and abstract. However, a major source of research findings is an article's tables and figures. The aim of this study is to: (1) explore the efficacy of applying a hybrid information extraction system to the problem of identifying research findings in the scientific literature and (2) improve results by processing article title, abstract and table/figure text.

PROGRAM COMPONENTS: The BioCommons comprises services addressing internal University of Washington, not-for-profit, for-profit, and regional and global clientele. The BioCommons is maintained and administered by the BioResearcher Liaison Team. The BioCommons architecture provides a highly flexible structure for adapting to rapidly changing resources and needs. EVALUATION MECHANISMS: BioCommons uses Web-based pre- and post-course evaluations and periodic user surveys to assess service effectiveness. Recent surveys indicate substantial usage of BioCommons services and a high level of effectiveness and user satisfaction. NEXT STEPS/FUTURE DIRECTIONS: BioCommons is developing novel collaborative Web resources to distribute bioinformatics tools and is experimenting with Web-based competency training in bioinformation resource use.

A knowledgebase system to enhance scientific discovery: Telemakus.

BACKGROUND: With the rapid expansion of scientific research, the ability to effectively find or integrate new domain knowledge in the sciences is proving increasingly difficult. Efforts to improve and speed up scientific discovery are being explored on a number of fronts. However, much of this work is based on traditional search and retrieval approaches and the bibliographic citation presentation format remains unchanged. METHODS: Case study. RESULTS: The Telemakus KnowledgeBase System provides flexible new tools for creating knowledgebases to facilitate retrieval and review of scientific research reports. In formalizing the representation of the research methods and results of scientific reports, Telemakus offers a potential strategy to enhance the scientific discovery process. While other research has demonstrated that aggregating and analyzing research findings across domains augments knowledge discovery, the Telemakus system is unique in combining document surrogates with interactive concept maps of linked relationships across groups of research reports. CONCLUSION: Based on how scientists conduct research and read the literature, the Telemakus KnowledgeBase System brings together three innovations in analyzing, displaying and summarizing research reports across a domain: (1) research report schema, a document surrogate of extracted research methods and findings presented in a consistent and structured schema format which mimics the research process itself and provides a high-level surrogate to facilitate searching and rapid review of retrieved documents; (2) research findings, used to index the documents, allowing searchers to request, for example, research studies which have studied the relationship between neoplasms and vitamin E; and (3) visual exploration interface of linked relationships for interactive querying of research findings across the knowledgebase and graphical displays of what is known as well as, through gaps in the map, what is yet to be tested. The rationale and system architecture are described and plans for the future are discussed.

An information extraction and representation system for rapid review of the biomedical literature.

With the rapid expansion of scientific research, the ability to effectively find or integrate new domain knowledge in the sciences is proving increasingly difficult. The development of methods and tools for assisting researchers to effectively ex-tract problem-oriented knowledge from heterogeneous and massive information sources, and for using this knowledge in problem-solving is one of the most fundamental research directions for the information and computer sciences today. There is a need for new tools to support more precise identification of relevant research articles and provide visual clues regarding relationships among the document sets. We present the Telemakus system in which aggregated citation information and extracted research findings are displayed in a schema-based document surrogate and an interactive mapping tool provides graphical displays of research inter-relationships from documents across a domain. This system is an innovative approach to creating useful and precise document surrogates and may re-conceptualize the way we currently represent, retrieve, and assimilate research findings from the published literature.

Tribal connections health information outreach: results, evaluation, and challenges.

In 1997, the National Library of Medicine (NLM), a component of the National Institutes of Health (NIH), initiated a program of intensified outreach to Native Americans, initially focusing on the Pacific Northwest in collaboration with the Pacific Northwest Regional Medical Library (PNRML). This initiative, known as the Tribal Connections Project, emphasized the establishment or strengthening of Internet connections at select Indian reservations and Alaska Native villages and related needs assessment and training. The hope was that these efforts would improve tribal access to health information available via the Internet and the Web. Phase I included sixteen tribal sites--eight in Washington, four in Alaska, two in Montana, and one each in Oregon and Idaho. Phase I results indicate that the project was successful in assessing local needs and building awareness of the Internet, forging new partnerships with and between the participating Indian reservations and Alaska Native villages and other organizations, making real improvements in the information technology (IT) infrastructure and Internet connectivity at fifteen of sixteen sites, and conducting training sessions with several hundred tribal participants across thirteen sites. Most importantly, the project demonstrated the key role of tribal community involvement and empowerment and contributed to development of an outreach evaluation field manual and the evolving concept of community-based outreach. The knowledge gained from Tribal Connections Project Phase I is helping refine and enhance subsequent NLM-sponsored tribal connections and similar community outreach efforts.

Program management and policy issues in information outreach: lessons from Tribal Connections.

With the advent of the Internet, American Indian/Alaska Native (AI/AN) communities in the Pacific Northwest have new opportunities to access high quality and relevant health information. The Pacific Northwest Regional Medical Library (PNRML), regional headquarters of the National Network of Libraries of Medicine, a program sponsored by the National Library of Medicine, sought to facilitate that access and worked with a selected group of sixteen tribes and native village consortia. The steps were: (1) work with AI/AN communities to arrive at mutually-agreeable health information connectivity objectives and long-term solutions, (2) provide funding to AI/AN communities to ensure Internet connectivity and the presence of Internet workstations for health workers and for the public, and (3) train in effective health information seeking. Community-based approaches helped the PNRML adjust policies and practice for improved information outreach to AI/AN communities in the region. The project participants, collaborating with our staff, successfully carried out many of the community goals and, at the same time, we gained insight about the variables that were barriers or facilitators of success. While we are coming at outreach from a library perspective, the policy and method lessons we learned could apply to a broad variety of outreach endeavors.

Low-bandwidth, low-cost telemedicine consultations in rural family practice.

BACKGROUND: Telemedicine, based on the use of interactive video consultations, is being used more commonly in rural settings. This development is potentially important to rural patients because there are fewer physicians, particularly specialist physicians, in rural areas. Declining costs of telemedicine equipment and transmission have created increased access to these technologies for rural family physicians and their patients. METHODS: This study considers satisfaction levels of rural family physicians, academic-based specialists, and rural patients in 130 consultations between rural physicians, rural patients, and urban academic specialists. To increase the practicability for rural use, low-cost equipment and low-bandwidth digital telephone transmission lines were utilized. Data were collected using questionnaires that were completed by patients, family physicians, and specialist consultants after each consultation. RESULTS: All categories of participants noted very high levels of satisfaction. CONCLUSION: Telemedicine-based consultations are well accepted by rural patients, rural family physicians, and urban academic specialist consultants. This approach could offer a useful adjunct to rural health care.

EpiQMS: an Internet application for access to public health data for citizens, providers, and public health investigators.

Access to epidemiologic data is critical to public health practice. Unfortunately, most published data are out of date and live databases are inaccessible because of issues of confidentiality, varying user needs, cost, security concerns, and other reasons. EpiQMS is a Web-based application that allows exploratory, statistical, and geographic analysis of public health data. Tables, graphs, and maps with adjustments for small areas are available at three levels: (1) the general public, (2) public health and medical practitioners, and (3) epidemiologists and health officers. The difference in each level is with respect to the presentation of small cell sizes and small geographies as set by the data set custodians.
