Joining Leapfrog’s National Healthcare Safety Network (NHSN) Group for ASCs is one of two options for authenticating your ambulatory surgery center for the purposes of requesting a security code to access the Online ASC Survey Tool.

In addition, ambulatory surgical centers (ASCs) are required to join Leapfrog’s NHSN Group for ASCs (ID: 57193) in order for Leapfrog to pull data on the following measures included in Section 4B NHSN Outpatient Procedure Module of the 2021 Leapfrog ASC Survey:

  • Same day outcome measures: patient burns, falls, “wrong” event, and all-cause hospital transfer/admission
  • Surgical site infections for Infections for breast surgery (BRST), laminectomy (LAM), herniorrhaphy (HER), and knee prosthesis (KPRO) using an All SSI SIR model

Leapfrog will also be downloading a copy of your facility’s 2020 Outpatient Procedure Component (OPC) Ambulatory Surgery Center (ASC) Annual Facility Survey.


Data will be available on the ASC Details Page, as well as scored and publicly reported by Leapfrog, starting in August for facilities that:

  • Join Leapfrog’s NHSN Group for ASCs and review/accept Leapfrog's Data Rights Template by July 21*,
  • Enter a valid NHSN ID in the Profile Section of the 2021 Leapfrog ASC Survey, and
  • Complete, affirm, and submit the 2021 Leapfrog ASC Survey by July 31

* Facilities are not required to “re-join” Leapfrog’s NHSN Group if they joined and conferred rights for the 2019 or 2020 Leapfrog ASC Survey. Facilities must review their Rights Acceptance Report before the July 21, 2021 NHSN join-by date.

FAQs Regarding Joining Leapfrog's NHSN Group for ASCs

Q: Will the data be shared with other members of the group?

A: No, an ASC that joins a group does not have access to any data from other facilities in the group. Data will only be shared with Leapfrog.

Q: How will the data be used?

A: The data will be used to score your facility and provide results for Section 4B NHSN Outpatient Procedure Component Module in the 2021 Leapfrog ASC Survey.

Q: What data is being requested?

A: The data being requested by Leapfrog is used to generate standardized infection ratios for surgical site infections within NHSN. It is also used to obtain information on your facility's same day outcome measures. Immediately after joining the Group, the facility will be taken to a screen listing the data that the Group is requesting access to, referred to as the “Data Rights Template.”  An   or in the template indicates that a particular piece of data is being requested by the Group. The Data Rights Template will automatically include all applicable procedures. The facility must select the “Accept” button at the bottom of the screen in order to accept the template of data rights and share data with Leapfrog.

Q: Will Leapfrog be collecting patient identifiers?

A: No, Leapfrog will not be collecting any patient identifiers. When reviewing the Data Rights Template, ASCs will see that we are requesting patient data “without any identifiers.”

Q: Who from our facility needs to complete the "join group" process within NHSN?

A: An administrative-level NHSN user is needed to join a Group within NHSN and complete the "Confer Rights" process.

Q: After joining the NHSN Group, what else is required?

A: When an ASC first joins the group they are asked to “confer rights” to the Leapfrog Group, which specifies the data that would be shared with Leapfrog.  Leapfrog has set up a Data Rights Template, which specifies the data we are requesting. Leapfrog requires that all ASCs in Leapfrog's NHSN Group review their Rights Acceptance Report annually, before the July 21, 2021 NHSN join-by-date. In addition to joining Leapfrog’s NHSN Group for ASCs, facilities must provide a valid NHSN ID in the Profile Section, and submit a 2021 Leapfrog ASC Survey. ASCs will be able to view the data that is being pulled into their Leapfrog ASC Survey by accessing their ASC Details Page beginning in August. ASCs need to download their reports and a copy of their 2020 Outpatient Procedure Component (OPC) Ambulatory Surgery Center (ASC) Annual Facility Survey from NHSN on the same day as Leapfrog to ensure that the SSI and SDOM data downloaded by Leapfrog is accurate. See important dates and deadlines in the table above as well as the PDF "ASC NHSN Guidance: Join the Group, Data"

Q: Will Leapfrog notify ASCs if the Data Rights Template is updated and they need to re-accept it within NHSN?

A: Yes, Leapfrog will e-mail the NHSN administrator of each facility that is a member of our NHSN group if we update the Data Rights Template. ASCs will be prompted to review the updated Data Rights Template and re-accept it when the NHSN administrator logs into NHSN. Failure to do so will result in leaving Leapfrog’s NHSN Group and Leapfrog will no longer be able to obtain NHSN data for your facility on the surgical site infection measures and the same day outcome measures. 

Q: How often is Leapfrog updating the data?  Won't regular updating cause changes to the data?

A: Leapfrog will obtain data from NHSN four times per Survey cycle. This allows Leapfrog to obtain data for new ASCs that may not join the NHSN Group by the first deadline and to use the most current data. The reporting period for the same day outcome measures and surgical site infections is the latest 6 months prior to Survey submission. Within a reporting period, an ASC’s data would only change if they update the surveillance or survey data submitted for that reporting period within NHSN.

Q: Who should ASCs contact if they have other questions?

A: Please contact Leapfrog’s Help Desk: Some questions may need to be re-directed to NHSN:
