Background The Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) is the most widely used health care–associated infection (HAI) and antimicrobial use and resistance surveillance program in the United States. Over 37,000 health care facilities participate in the program and submit a large volume of surveillance data. These data are used by the facilities themselves, the CDC, and other agencies and organizations for a variety of purposes, including infection prevention, antimicrobial stewardship, and clinical quality measurement. Among the summary metrics made available by the NHSN are standardized infection ratios, which are used to identify HAI prevention needs and measure progress at the national, regional, state, and local levels. Objective To extend the use of geospatial methods and tools to NHSN data, and in turn to promote and inspire new uses of the rendered data for analysis and prevention purposes, we developed a web-enabled system that enables integrated visualization of HAI metrics and supporting data. Methods We leveraged geocoding and visualization technologies that are readily available and in current use to develop a web-enabled system designed to support visualization and interpretation of data submitted to the NHSN from geographically dispersed sites. The server–client model–based system enables users to access the application via a web browser. Results We integrated multiple data sets into a single-page dashboard designed to enable users to navigate across different HAI event types, choose specific health care facility or geographic locations for data displays, and scale across time units within identified periods. We launched the system for internal CDC use in January 2019. Conclusions CDC NHSN statisticians, data analysts, and subject matter experts identified opportunities to extend the use of geospatial methods and tools to NHSN data and provided the impetus to develop NHSNViz. The development effort proceeded iteratively, with the developer adding or enhancing functionality and including additional data sets in a series of prototype versions, each of which incorporated user feedback. The initial production version of NHSNViz provides a new geospatial analytic resource built in accordance with CDC user requirements and extensible to additional users and uses in subsequent versions.
Strengthening the capacity of public health systems to protect and promote the health of the global population continues to be essential in an increasingly connected world. Informatics practices and principles can play an important role for improving global health response capacity. A critical step is to develop an informatics agenda for global health so that efforts can be prioritized and important global health issues addressed. With the aim of building a foundation for this agenda, the authors developed a workshop to examine the evidence in this domain, recognize the gaps, and document evidence-based recommendations. On 21 August 2011, at the 2011 Public Health Informatics Conference in Atlanta, GA, USA, a four-hour interactive workshop was conducted with 85 participants from 15 countries representing governmental organizations, private sector companies, academia, and non-governmental organizations.The workshop discussion followed an agenda of a plenary session - planning and agenda setting - and four tracks: Policy and governance; knowledge management, collaborative networks and global partnerships; capacity building; and globally reusable resources: metrics, tools, processes, templates, and digital assets. Track discussions examined the evidence base and the participants’ experience to gather information about the current status, compelling and potential benefits, challenges, barriers, and gaps for global health informatics as well as document opportunities and recommendations.This report provides a summary of the discussions and key recommendations as a first step towards building an informatics agenda for global health. Attention to the identified topics and issues is expected to lead to measurable improvements in health equity, health outcomes, and impacts on population health. We propose the workshop report be used as a foundation for the development of the full agenda and a detailed roadmap for global health informatics activities based on further contribution from key stakeholders. The global health informatics agenda and roadmap can provide guidance to countries for developing and enhancing their individual and regional agendas.
BACKGROUND The Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) is the most widely used healthcare-associated infection (HAI) and antimicrobial use and resistance (AUR) surveillance program in the United States. Over 37,000 healthcare facilities participate in the program and submit a large volume of HAI and AUR surveillance data. These data are used by the facilities themselves, CDC, and other agencies and organizations for a variety of purposes, including infection prevention, antimicrobial stewardship, and clinical quality measurement. Among the summary metrics made available by NHSN are standardized infection ratios (SIRs), which are used to identify HAI prevention needs and measure progress at the national, regional, state and local levels. OBJECTIVE To extend the use of geospatial methods and tools to NHSN data, and in turn to promote and inspire new uses of the rendered data for analysis and prevention purposes, we developed a web-enabled system that enables integrated visualization of HAI metrics and supporting data.
