input, storage, processing and output

- these components combine to form a system that helps end users, public health professionals, capture, manage, and analyze information to inform decision-making and drive business processes.

clinical health

- has a primary focus on individuals with health problems (such as disease or injury), and a -primary strategy of treatment after the occurrence of the disease or injury

public health (PH)

- has a primary focus on populations, and a primary strategy of prevention (of disease, injury, disability, or environmental impact).

Council for State and Territorial Epidemiologists (CSTE)

- identified informatics as a top training priority to support achievement of public health department capacity needs

Public Health 2.0

- in the late twentieth century through the early twenty-first century, public health matured as a service and expanded in response to the Institute of Medicine's The Future of Public Health report - public health services transitioned from a focus on infectious to chronic diseases, and responded to major epidemics like HIV/AIDS as well as SARS

LOCAL LEVEL OF PUBLIC HEALTH

- includes not only county HDs and metropolitan area HDs, but also tribal public health and regional collaborative organizations

Programming

- instructions that tell computers how to store, manipulate, transform, and display data

Recognition

- is a sign that informatics is maturing as a discipline within public health.

STATE LEVEL OF PUBLIC HEALTH

- is considered to hold the primary responsibility for public health in the US

Public Health Informatics

- is the defining factor that differentiates PH Informatics from all the other health informatics specialties, such as bioinformatics, clinical informatics, and other sub-disciplines

Centers for Disease Control and Prevention (CDC)

- nation's leading science-based, data-driven, service organization that protects the public's health

Context

- operation within a governmental context, as opposed to private, profit seeking context

public health informatics (PHI)

- primary domain = public health - which itself is composed of several important disciplines: epidemiology; biostatistics; social and behavioral sciences; health administration; and environmental science

Communicable Disease Center

- product of the Malarial Control in War Areas (MCWA) program established in Atlanta, GA in 1942

one health

- recognizes the connection between people's health, animal health, and the environment

Public Health 1.0

- refers to the period from the nineteenth century through the twentieth century when public health established itself as an essential government service

The Patient Protection and Affordable Care Act of 2010

- signaled a shift in the market towards "bundled payments" that reward maintenance of and improvements in health with minimal utilization of health care services.

London Bills of Mortality

- sixteenth century, the recording of vital statistic ·-History of PH in US began on 1874

information system (IS)

- sometimes referred to as INFORMATION AND COMMUNICATIONS TECHNOLOGIES or ICT - are common in medicine, education, and every other domain

Current State

- support the public health enterprise. In 2017, the Association for State and Territorial Health Officers (ASTHO) added informatics as a health department role to its Public Health Workforce and Information Needs Survey

Networking

- technical methods to connect two/more computer systems

Prevention

- the application of information science and technology to focus on prevention of disease or injury, rather than treatment of existing conditions in individuals

Population health

- the application of information science and technology to further the health of populations rather than of individuals

Public Health Information Systems

- are the technical components used to support the business of public health organizations

informatics

- brings methods, knowledge, and theories from both computer science and information science to support the field of public health

Data sources and partners

- can be considered as the input for PHI applications

INFORMATIK

- denote automatic information processing (means computer science in German)

Public Health 3.0

- desire PH organizations to form vibrant, structured, cross sector partnerships in which they leverage timely, actionable data and metrics to guide population decision-making - The vision is a call-to-action statement in which HHS challenges the public health enterprise to invest in its infrastructure, move towards interoperability with the health care system, and implement intelligent public health IS that align with the National Academy of Medicine's concept of the Learning Health System

The Applied Public Health Informatics Competency Model

- developed by the Public Health Informatics Institute (PHII), built upon earlier work to develop a framework for the knowledge and skills needed for PHI

Information science

- focuses on the effective collection, storage, management, retrieval, and use of information among humans in the context of social, organizational, and individual needs

Computer science

- focuses on the methods and techniques to store, manipulate, transform, and display data and information by means of computer systems

one health

- "collaborative, multisectoral, and transdisciplinary approach — working at the local, regional, national, and global levels —with the goal of achieving optimal health outcomes recognizing the interconnection between people, animals, plants, and their shared environment"

public health informatics (PHI)

- "systematic application of information and computer science and technology to public health (PH) practice, research, and learning"

Communicable Disease Center

- 1946, ancestor of today's Centers for Disease Control and Prevention (CDC) was established

mHealth and uHealth

- A rise in the availability and adoption of devices (e.g., smartphones, tablets, smart watches) is driving a move towards mHealth (mobile health) and uHealth (ubiquitous health)

The Patient Protection and Affordable Care Act of 2010

- ACA, also known as Obamacare - ushered in a new era in health care reform that focuses on population health

Precision Public Health

- Advances in genomics now enable doctors to precisely prescribe a medication regimen to treat diseases, especially cancer, based on an individual's genetic profile.

informatics

- Coined by Karl Steinbuch

Input

- Data and information; organizations typically collect or capture data and information from one or more sources - Population surveys; vaccination records; census data; birth certificate data

Janet Hamilton, MPH

- Director of Science and Policy at the Council for State and Territorial Epidemiologists - "data is moving slower than the disease" - "...paper records, phone calls, spreadsheets and faxes requiring manual data entry are still in widespread use..." in public health

Public Health 3.0

- In 2016, the US Department of Health and Human Services laid out a vision for what it termed 'Public Health 3.0

Processing

- Includes information retrieval (e.g., search) as well as data integration and analysis functions; organizations often use more than one application to perform these functions as part of the information system - SAS™, R, enterprise master index; Citrix; internet browser

Precision Public Health

- Increasingly health care systems are implementing 'precision medicine' programs to treat disease through designer drugs and tailored therapy

smallpox

- One of the biggest success stories in twentieth century PH - deaths of around 300 million people, but a dedicated global PH vaccination program eradicated the disease in 1977

Output of PHI Efforts

- PH data are gathered in order to promote PH goals - PHI aims to advance the "business of public health" which is to improve the health of populations.

clinical health

- Preventive measures are usually not the primary focus, although they may be a secondary focus.

Storage

- Repository for data and information; organizations use a combination of hard drives, "mapped" network drives, servers, and cloud-based storage components to manage the data and information captured by the organization - Relational database; virtual file folders; CSV files; Google Drive

INFORMATIQUE

- Russian denoting the theory of scientific information

Public Health 2.0

- Systematic development of public health governmental agency capacity across the United States. - Focus limited to traditional public health agency programs

The Applied Public Health Informatics Competency Model

- The framework included broad categories of o informatics principles and strategic thinking; o informatics standards and interoperability; o project management; o knowledge of infrastructure, including hardware, software, and networks; o effective communication; o evaluation of workflows and technology; o data analysis, visualization, and reporting; o policy and regulations

Output

- The result of the processing; most often the output takes the form of a report, graph, chart, table, or map. The output could be in the format of an electronic message, like an email, that is sent to another organization - Map of neighborhoods with high incidence of disease; list of newly diagnosed cases of measles in county; graph depicting the prevalence rate of chlamydia over the past 3 years

Precision Public Health

- These efforts are guided by advanced-omics (genomics, proteomics, etc.) but they also take advantage of modern informatics approaches like 'predictive analytics' as well as machine learning

Public Health 3. 0

- addresses the collaboration necessary to achieve that integration - enhance and broadened public health practice that goes beyond traditional public department function

Causal chain

- applications that target points in the causal chain leading to disease, injury, or disability

information system (IS)

- are the primary tools by which PH informatics professionals design, implement, and operate systems to facilitate the collection, management, analysis, use, and exchange of data and information.

information system (IS)

- used in everyday life is an email client like Microsoft Outlook™ or Google's Gmail. - used in public health include the Behavioral Risk Factor Surveillance System (BRFSS) and the Electronic Surveillance System for the Early Notification of Community-based Epidemics (ESSENCE).

post-World War II era

- ushered in the Age of Computing in which the world sought to improve the speed of computation, a required ingredient to put humankind on the moon as well as play video games

Public Health Informatics (PHI)

- which expresses its interdisciplinary nature and denotes its application to all aspects of public health

Public Health 1.0

-Tremendous growth of knowledge and tools for both medicine and public health -Uneven access to care and public health

Public Health 3.0
