National Healthcare Safety Network (NHSN) Information

NHSN is a voluntary, secure, internet-based surveillance system that integrates patient and healthcare personnel safety surveillance systems. It is managed by the Division of Healthcare Quality Promotion (DHQP) at the Centers for Disease Control and Prevention (CDC) in Atlanta. NHSN enables healthcare facilities to collect and use data about healthcare-associated infections, multi-drug resistant organisms, and other adverse events. The Michigan Department of Community Health is using NHSN to collect information from hospitals about healthcare-associated infections (HAIs) in order to monitor and characterize the burden of HAIs in Michigan. This page provides a listing of commonly used NHSN links and explanation about the MDCH SHARP Unit's use of NHSN data. If you would like to suggest a link be added to this page or if you find problems with the existing links, please let us know. See the About the SHARP Unit page for contact information. 



CDC NHSN Information 

Enrollment in NHSN  

Enrollment in the NHSN is through the CDC; however, the MDHHS SHARP Unit can assist with questions about the NHSN. Healthcare facilities wishing to enroll in NHSN should go to the CDC website for NHSN enrollment requirements. Enrollment forms can be found at the CDC NHSN Data Collection Forms website. 

Enrollment Requirements for Inpatient Hospital Inpatient Quality Reporting Program 
Provides a step-by-step guide on training and enrollment requirements for the Centers for Medicare and Medicaid Services (CMS) Hospital Inpatient Quality Reporting Program, formerly known as Reporting Hospital Quality Data for Annual Payment Update (RHQDAPU). 

Training on NHSN  

Multiple webcast lectures are available online for those who need to fulfill the training requirements of the NHSN, or for those who need a refresher on a particular topic. Training is also available on the various modules of the NHSN.

NHSN Data Analysis  

Infection control staff may be interested in comparing their HAI rates to the national average or benchmark. The latest national benchmarks for device associated and procedure associated modules can be found here:

NHSN Summary Data Reports  
First State-Specific Healthcare-Associated Infections Summary Data Report, CDC's National Healthcare Safety Network (NHSN) 
Composite statistics summarizing CLABSI HAI data available from NHSN at the national and state levels. The Standardized Infection Ratio (SIR) is used to compare the actual number of HAIs in a facility or state with the baseline U.S. experience, adjusting for several risk factors that have been found to be most associated with differences in infection rates.


The MDHHS SHARP Unit Surveillance Project  
At the end of August 2009, the then Michigan Department of Community Health (MDCH) Surveillance for Healthcare-Associated and Resistant Pathogens (SHARP) Unit received funding from the American Recovery and Reinvestment Act (ARRA) to expand its efforts in the surveillance and prevention of healthcare-associated infections. Currently, the MDHHS SHARP Unit is still collecting voluntarily reported data via NHSN. As of September 2015, there are 104 hospitals in Michigan voluntarily sharing NHSN data with the SHARP Unit.
Data Use Agreement  
Hospitals who wish to participate in HAI surveillance with the MDCH SHARP Unit using NHSN will first need to enroll in NHSN (see links above), then sign an MDCH SHARP Data Use Agreement. The Agreement describes the purposes of the surveillance and provides assurances of confidentiality of the data. Click here to view a sample copy of the Data Use Agreement. To obtain an official copy of the Data Use Agreement, please contact Allison Murad. Two original signed copies of the Agreement should be returned to the SHARP Unit. See the About the SHARP Unit page for contact information.
