The collaborations that the Centers for Disease Control and Prevention’s (CDC’s) National Healthcare Safety Network (NHSN) Team has with the Council of State and Territorial Epidemiologists (CSTE) and the Centers for Medicare and Medicaid Services (CMS) provide important momentum for advances in healthcare-associated infection (HAI) surveillance at the local, state, and federal levels. The work that has been accomplished and new efforts underway continue to extend NHSN’s capacity to produce accurate and valid surveillance data for effective prevention of HAIs in a variety of healthcare settings. As a result of state and CMS requirements, NHSN has emerged as the primary system used for HAI surveillance and reporting in the U.S. This development, in turn, has led to important changes and improvements to NHSN. These changes have been implemented for the purposes of reducing subjectivity, maximizing standardization, preventing data entry errors, improving simplicity and completeness of data entry, and more accurately defining the facility types and locations from which data are reported. Major enhancements include revisions and additions to better standardize HAI criteria and definitions and risk adjust metrics for comparative purposes, new reporting for antimicrobial resistance data, and additional output options for analysis and reports. The NHSN system is also stabilized with architecture upgrades as necessary. Electronic reporting capability through Clinical Document Architecture (CDA) will be expanded to include antimicrobial resistance reporting through the Antimicrobial Use and Resistance Module and always includes enhancements for improved reporting. New additions planned for the NHSN system include a new Component specifically for Dialysis Event reporting and the Outpatient Procedure Component for reporting from Ambulatory Surgery Centers. Together the revisions serve to improve the user interaction and experience with NHSN and the completeness and quality of the data that are analyzed and reported out of the system. During this session users will be asked to provide feedback and input on current and future enhancements to the NHSN system. The impact of state mandates and CMS rules to users, stakeholders, and the system will be discussed as a group. The intent is to make this an informative and interactive NHSN presentation and discussion.
