Public health informatics uses technology and information systems to advance strategies such as surveillance, prevention, preparedness, outbreak management, electronic laboratory reporting, predictive modeling and health promotions.
What is public health informatics?
Public health informatics is a subdomain of the larger field known as biomedical or health informatics. Health informatics is not synonymous with the term health information technology (IT). Although the concept of health IT encompasses the use of technology in the field of health care, one can think of health informatics as defining the science, ...
What is public health surveillance?
Public health surveillance has benefitted from, and has often pioneered, informatics analyses and solutions. However, the field of informatics also serves other facets of public health including emergency response, environmental health, nursing, and administration. Public health informatics has been defined as the systematic application ...
What is the responsibility of a public health leader?
Public health leaders have the responsibility of examining their workforce and making the conscious decisions to augment it with public health informatics expertise. Leadership also requires the ability to assemble the appropriate set of stakeholders when addressing 21 st century public health surveillance challenges.
What is EHR and HIE?
EHR and HIE systems collate information about individual patients from different information systems (e.g. , registration, clinical record, laboratory, and imaging) and through information exchange or aggregation from across different provider entities . Adoption of the systems is being incentivized and facilitated by the Health Information Technology for Economic and Clinical Health (HITECH) Act in the United States. Enacted as part of the American Recovery and Reinvestment Act (ARRA) of 2009 ( 4 ), the HITECH act authorized Medicaid and Medicare financial incentives for providers to adopt and use EHRs and authorized funding for the Office of the National Coordinator for Health Information Technology (ONC) to encourage health IT adoption, aid in standard-setting, build work force, and support state- and regional-level development of HIE.
What is public health?
Instead, public health focuses on improving and protecting community health and well-being, with an emphasis on prevention among large groups of people. Those with public health degrees keep communities healthy through child wellness, disease prevention, education, disaster relief, clean water, access to healthcare, and much more.
What is the job of a public health official?
But public health officials—many of whom may hold public health degrees—work on a daily basis to keep people healthy and safe, locally and around the world, by preventing disease and injury.
What is public health information?
Recognized as information intensive, healthcare requires timely, accurate information from many different sources generated by health information systems (HIS). With the availability of information technology in today's world and its integration in healthcare systems; the term “Public Health Informatics (PHI)” was coined and used. The main focus of PHI is the use of information science and technology for promoting population health rather than of individuals. PHI has a disease prevention rather than treatment focus in order to prevent chain of events or disease spread. Moreover, PHI often operates at the level of government rather than at the private sector. This review article provides an overview of the field of PHI and compares between paper based surveillance system and Public Health Information Networks (PHIN). The current trends and future challenges of applying PHI systems in KSA were also reported.
Why is electronic health records important?
The use of electronic health records further enhances the early detection of cases, clusters, outbreaks and trends of communicable diseases and environmental hazard exposures.
How did PHI play a role in the collection and analysis of real-time data that were introduced right after the
PHI played a role in the collection and analysis of real-time data that were introduced right after the bioterrorism attack.
Why is surveillance important in public health?
Surveillance in public health is the collection, analysis and interpretation of data that are important for the prevention of injury and diseases. Through available data, possible early detection of outbreaks can be achieved through timely and complete receipt, review, and investigation of disease case reports. An inclusive surveillance effort supports timely investigation and identifies data needs for managing public health response to an outbreak or terrorist event. 5 Worldwide, governments are strengthening their public health disease surveillance systems, taking advantage of modern information technology to build an integrated, effective, and reliable disease reporting system. 6 A surveillance system, such as syndromic surveillance systems, could collect symptoms and clinical features of an undiagnosed disease or health event in near real time that might indicate the early stages of an outbreak or bioterrorism attack. For instance, local or regional public health departments could alert all the clinicians within an HIO about unique cases of a highly resistant infectious organism or a widespread of communicable diseases. Consequently, HIO can play an important role as part of PHI in providing available patient data in conditions of natural disaster when paper-based records might be destroyed or unavailable.
Why is paper based surveillance important?
Generating adequate and meaningful data in a short time could not be achieved with paper-based surveillance systems because of the difficulty in retrieving the data. Furthermore, paper-based systems incur costs in terms of paper, labor, and space for storing. Paper-based data cannot be shared easily with other systems and are more susceptible to privacy and confidentiality breaches. The use of electronic health records further enhances the early detection of cases, clusters, outbreaks and trends of communicable diseases and environmental hazard exposures. These characteristics improve the chances of detection of disease surveillance, epidemics, natural disasters and bioterrorism events. The use of systems, such as real-time outbreak detection systems, allows for the real time, daily detection, analysis and dissemination of outbreak information to the targeted populations and agencies. The use of a geographic information system, such as HealthMap, has further improved the identification, monitoring, alerting and responding to emerging diseases, pandemics, bioterrorism and natural disasters, not only at the national but at the global level.8
