A national agenda for public health informatics.

The American Medical Informatics Association 2001 Spring Congress brought together the public health and informatics communities to develop a national agenda for public health informatics. Discussions on funding and governance; architecture and infrastructure; standards and vocabulary; research, evaluation, and best practices; privacy, confidentiality, and security; and training and workforce resulted in 74 recommendations with two key themes: (1) all stakeholders need to be engaged in coordinated activities related to public health information architecture, standards, confidentiality, best practices, and research and (2) informatics training is needed throughout the public health workforce. Implementation of this consensus agenda will help promote progress in the application of information technology to improve public health.     

Understanding public health informatics competencies for mid-tier public health practitioners: a web-based survey

The literature suggests that there is a need for measuring public health informatics (PHI) competency to further understand whether current educational modules and modalities meet the needs of PHI practitioners and researchers to perform their jobs more effectively, particularly for mid-tier practitioners that constitute the majority of public health workers in the USA. The present study seeks to update current knowledge of the perceptions and experiences of PHI competencies proposed by the U.S. Council on Linkage in Public Health specifically for mid-tier PH practitioners and researchers. The results were collected and analyzed by using a Web-based survey (WBS) method administered among both practitioners and researchers. Researchers first compiled a draft list of candidate competency set by incorporating existing competency areas provided by: 1) the Council on Linkage; and by 2) those proposed by the USA's Centers for Disease Control CDC Public Health Informatics Work Group. Nine sets of competency statements with 120 competency items and demographic information of respondents were included in the WBS. The online survey instruments were pilot-tested accordingly to incorporate feedback from respondents of the pilot. Fifty-six subjects were recruited from PH experts who were: 1) members of the Health Informatics Information Technology (HIIT) group of American Public Health Association; and, 2) members from the Community of Science (COS) Website who were the first authors published in the PHI field from PubMed. The sample included diverse backgrounds of PHI workers. They expressed an increased need for training to improve their PHI competencies. Respondents agreed that four competency sets should be adequately represented, including Leadership and System Thinking Skills (82%), followed by Financial Planning and Management Skills (79%), Community Dimensions of Practice Skills (77%), and Policy Development/Program Planning Skills (63%). The findings parallel current literature indicating that there exists an expressed need for clarification of the public health practitioner's job-specific informatics competency. Findings of expressed needs for basic computer literacy training and community-based practice were consistent with those of the literature. Additional training and resources should be allocated to address the competency of leadership, management, community-based practice and policy advocacy skills for mid-tier public health practitioners to perform their jobs more effectively. Only when healthcare organizations properly identify PHI competency needs will public health practitioners likely improve their overall informatics skills while improving diversification for contribution across multiple settings.     

Enhancing surveillance for hepatitis C through public health informatics

Disease surveillance for hepatitis C in the United States is limited by the occult nature of many of these infections, the large volume of cases, and limited public health resources. Through a series of discrete processes, the Massachusetts Department of Public Health modified its surveillance system in an attempt to improve timeliness and completeness of reporting and case follow-up of hepatitis C. These processes included clinician-based reporting, electronic laboratory reporting, deployment of a Web-based disease surveillance system, automated triage of pertinent data, and automated character recognition software for case-report processing. These changes have resulted in an increase in the timeliness of reporting.     

Public health informatics: improving and transforming public health in the information age.

Development of effective public health information systems requires understanding public health informatics (PHI), the systematic application of information and computer science and technology to public health practice, research, and learning. PHI is distinguished from other informatics specialties by its focus on prevention in populations, use of a wide range of interventions to achieve its goals, and the constraints of operating in a governmental context. The current need for PHI arises from dramatic improvements in information technology, new pressures on the public health system, and changes in medical care delivery. Application of PHI principles provides unprecedented opportunities to build healthier communities.     

Baseline assessment of public health informatics competencies in two Hudson Valley health departments

Information technology has the capability to improve the way public health is practiced. Realization of this potential is possible only with a workforce ready to utilize these technologies. This project team assessed informatics competencies of employees in two county departments of health. The goal was to determine the status quo in terms of informatics competencies by surveying current levels of proficiency and relevance, and identify areas of needed training. A survey was adapted from the recommendations of a Working Group document by the Centers for Disease Control and Prevention and administered to all employees in the two health departments. Respondents evaluated proficiency and relevance for each of 26 recommended competencies. A gap score was generated between these two measures; results were compared to the recommendations of the Working Group. The following data for each job level are presented: mean gap scores by competency class; the percentage of respondents demonstrating a gap in the competencies reported to be most relevant; and the percentage of respondents meeting the target recommendations of the Working Group. The percentage of respondents who reached the targets was low in higher-level staff. And overall, employees reported low levels of relevance for most of the competencies. The average public health employee does not feel that prescribed informatics competencies are relevant to their work. Before the public health system can take advantage of information technology, relevant employee skills should be identified or developed. There needs to be a shift in thinking that will recognize the promise of information technology in everyday work.     

Beyond informatics: an electronic community infrastructure for public health.

Public health agencies are in the early stages of building an electronic infrastructure that will link them to each other and eventually to the "information superhighway." Emphasis in planning and development is on data systems and the information and training services that can enhance essential public health services. This article argues for a larger vision of the potential of electronic networks for public health. It discusses the health and other challenges facing public health, the limitations of conventional efforts, and the emerging consensus on public health core functions. Finally, it examines current and potential uses of information technology. The article concludes by proposing that the public health community should develop a collaborative and inclusive vision of public health in an electronic world and provide guidance and support for agency implementation to ensure a stronger system that can meet the health and health equity challenges ahead.     

Health informatics education: an opportunity for public health in Canada

Health information infrastructure is being developed across Canada, and health informatics education should be a component of the emerging infrastructure. However, educational opportunities do not appear to be developing in pace with infrastructure. This study characterizes the required education, and describes specific issues facing the development of health informatics education. Twenty-six key informants were interviewed, and responses were analyzed to identify major themes. Subjects agreed that the current capacity for health informatics education is inadequate. Also, limited expertise could adversely affect health infostructure implementation and health system performance. A need was identified for both advanced and basic education. Four issues facing the development of health informatics education in Canada were consistently identified: awareness, collaboration, funding, and human resources. Public health is well positioned to play a central role in health informatics education due to its historical basis in handling health information, and its developing expertise in health informatics applications.

Development and evaluation of public health informatics at University of Washington.

Public Health Informatics (PHI) education began at the University of Washington (UW) with a Summer Institute in 1995. The Biomedical and Health Informatics graduate program, which is housed in the School of Medicine, is an interdisciplinary, multi-school program. It demonstrates the UW's cooperative efforts in advancing informatics, encompassing the schools of public health, medicine, nursing, dentistry, pharmacy, information and graduate schools in computer science. This article provides an overview of the developmental milestones related to activities in PHI and describes the evaluation strategy and assessment plan for PHI training at the UW (http://phig.washington.edu).     

Issues and opportunities in public health informatics: a panel discussion.

A panel was convened at the American Medical Informatics Association Spring Congress to discuss issues and opportunities that arise when informatics methods, theories, and applications are applied to public health functions. Panelists provided examples of applications that connect efforts between public health and clinical care, emphasizing the need for integration of clinical data with public health data and the analysis of those data to support surveillance and informed decision making. Benefits to be gained by both medical informatics and public health at the interface were evident; both encounter the same major issues including privacy, systems integration, standards, and many more.

Nutrition and health informatics

The Internet is playing an increasingly important role in the lives of people across the globe. The areas of nutrition and health are among the fastest growing areas of interest on the Internet, and are the main topics many people search for when ‘surfing’ the Internet. As the information age progresses, consumers will become more health literate and health professionals will have to ensure they can provide advice as to how their patients can find reliable web sites among the many misleading and biased sites on the Internet. This paper predicts the role the Internet will soon play in everyday life, and provides a guide to assessing the reliability of health and nutrition web sites.     

The public health enterprise: examining our twenty-first-century policy challenges

This paper examines the public health enterprise and its policy challenges in the twenty-first century. Among the many challenges public health faces, we include here collaboration across a broad range of stakeholders, the public health infrastructure, agreement on public health's essential services, preparedness, accountability and measurement, workforce, and a research agenda. Two Institute of Medicine reports on the future of public health have set the context for a more in-depth review of the public health workforce and infrastructure. Policy advocates must ask, however, why, if the way and the means are so clear, the public health system is still in disarray.
