11 Describe the purpose of the system.

Describe the type of information the system will
collect, maintain (store), or share. (Subsequent
12
questions will identify if this information is PII and ask
about the specific data elements.)
Provide an overview of the system and describe the
13 information it will collect, maintain (store), or share,
either permanently or temporarily.
14 Does the system collect, maintain, use or share PII?

The major purpose of the National Health Safety Network
(NHSN) is to equip participating healthcare facilities to enter
data associated with healthcare safety events, such as surgical
site infections, anti-microbial use and resistance, bloodstream
infections, and healthcare worker vaccinations. NHSN provides
analysis tools that generate reports using the aggregated data
(reports about infection rates, national and local comparisons,
etc.). Participating NHSN healthcare facilities can access webbased screens that allow them to enter data associated with
healthcare safety events. These data are captured in a
relational database at the CDC. Participants can then use NHSN
analysis tools to generate reports that are displayed on their
web browser.
NHSN addresses data collection from healthcare facilities to
permit valid estimation of adverse events among patients or
residents and healthcare personnel. Similarly, it provides
facilities with risk-adjusted metrics that can be used for interfacility comparisons and local quality improvement activities.
NHSN also allows for the opportunity of collaborative research
studies with participating facilities that describe the
epidemiology of emerging health care-associated infections
(HAIs) and pathogens, assess the importance of potential risk
factors, further characterize HAI pathogens and their
mechanisms of resistance, and evaluate alternative
surveillance and prevention strategies. The NHSN Agreement
ensures compliance with legal requirements – including state
or federal laws, regulations, or other requirements – for
mandatory reporting of facility-specific adverse event,
prevention practice adherence, and other public health data.
NHSN enables healthcare facilities to report data to the Centers
for Medicare & Medicaid Services (CMS) of the U.S. Department
of Health and Human Services (DHHS) in fulfillment of CMS’s
quality measurement reporting requirements for those data.
Considering the Coronavirus Disease (COVID-19) Pandemic,
CDC created the capability for COVID-19 surveillance in NHSN,
enabling data collection reported by Long-Term Care Facilities
(LTCFs) and Outpatient Dialysis Facilities. This data is reported
through different pathways within the NHSN COVID-19
Modules for LTCFs and Outpatient Dialysis Facilities.
The type of information the NHSN system collects is described
below:
Patients: Patient identification number (may be a medical
record number), gender and date of birth. For some patients,

17 How many individuals' PII is in the system?

18 For what primary purpose is the PII used?

19

Describe the secondary uses for which the PII will be
used (e.g. testing, training or research)

1,000,000 or more
Data from NHSN is used for tracking of healthcare-associated
infections, antibiotic use and resistance, and surveillance of
COVID-19.
Data from NHSN is also used as a guide for infection
prevention activities that protect patients.

20 Describe the function of the SSN.

SSNs are vital to the overall operation of NHSN because
hospitals whose data is entered into NHSN may use NHSN to
track a patient by SSN. Also state public health officials who
have been granted access to the data in their state by their
constituent hospitals may require access to patient SSNs. The
state of Pennsylvania for example requires by law the
reporting of Healthcare Associated Infections using NHSN and
as part of the state mandate requires the records to be
identified by SSNs. This allows Pennsylvania to download data
from NHSN about patients in their state and link that data to
payment information.

20a Cite the legal authority to use the SSN.

Describe the process in place to notify individuals
25 that their personal information will be collected. If
no prior notice is given, explain the reason.

26

Is the submission of PII by individuals voluntary or
mandatory?

Describe the method for individuals to opt-out of the
collection or use of their PII. If there is no option to
27
object to the information collection, provide a
reason.

The NHSN User Support Helpdesk currently tracks for
accounting for disclosures via management of an organized
email folder system.
NHSN is a public health surveillance system and does not
require obtaining consent from individuals whose data are
submitted and stored in the system. When facilities agree to
the NHSN Agreement to Participate and Consent upon
enrollment in NHSN, they are made aware of the purposes of
NHSN and how the data reported to NHSN may and may not
be used, including PII.
Voluntary
Mandatory
There is no option to object to the information collection
because NHSN is a public health surveillance system that
requires healthcare facilities to submit patient data for public
health surveillance.

Technical controls include application level role based access
controls; encryption of PII at rest and in transit; standard
baseline configurations for IT assets; server audit and
accountability measures; and continuous monitoring of system
resources to identify vulnerabilities and ensure adherence to
organizationally defined minimum security requirements. In
addition, the system is protected by residing within SAMS and
requires each user to have CDC-approved identity proofing in
order to access the system.
Physical controls surrounding the system's data centers
include gated campuses with 24-hour security guards to
enforce access restriction; key card access to campus buildings;
and access control lists further limiting physical access to
sensitive areas such as the data centers.

General Comments

Q10: In response the COVID-19 pandemic, the National Healthcare Safety Network (NHSN) augmented the
existing NHSN system to monitor and analyze the capacity of the domestic healthcare system so that
federal, state, and local officials can adjust their response efforts. This augmentation encompassed the
distinct COVID-19 reporting modules including a hospital capacity and patient impact COVID-19 module
for hospitals, a long-term care facility (LTCF) COVID-19 module, an outpatient dialysis module, and
collection of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) point-of-care antigen test
data from long-term care facilities. On May 8, 2020, the Centers for Medicare and Medicaid Services (CMS)
published an Interim Final Rule with Comment Period to mandate that all approximately 15,600 CMScertified nursing homes report standard COVID-19 data to NHSN through the LTCF COVID-19 module. As
part of this rule, CMS publicly reports facility-level nursing home data. Facilities began to submit data to
this module on May 17, 2020 and must submit data through NHSN at least once every seven days. It
should be noted that reporting into the hospital capacity and patient impact COVID-19 module began in
March of 2020 and ended on July 15, 2020. Reporting into the dialysis module began in November of
2020. SARS-CoV-2 point-of-care antigen test data from long-term care facilities is reported to NHSN and
then transmitted via HL7 Clinical Documentation Architecture to the Association of Public Health
Laboratories’ Informatics Messaging Services (AIMS) platform. The data is then provided to State Health
Departments and HHS.
In addition to NHSN’s response to the pandemic, NHSN’s new Neonatal Component is expected to launch
during the winter of 2020/2021. This component will focus on premature neonates and the healthcareassociated events that occur as a result of their prematurity. This component will be released with one
module, which includes Late Onset-Sepsis and Meningitis, which are common complications of extreme
prematurity. There is no manual entry available to users for the new neonatal component. Both
numerator and denominator data will be imported into the Clinical Document Architecture (CDA) via
electronic data transfer. This will allow users to obtain data submitted via CDA and focus on prevention
activities within their respective hospitals or facilities. All data collected in these modules and in the POC
initiative fall under the personally identifiable information (PII) previously specified in the hospital
acquired infection (HAI) data collected by NHSN.
