5-Step Enrollment for Ambulatory Surgery Center Facilities

Note: The following instructions are for ambulatory surgical centers (ASCs) that must enroll in NHSN for the purpose of fulfilling CMS’s Ambulatory Surgical Center Quality Reporting (ASCQR) Program requirements.  Participating CMS-licensed ASCs will be required to report healthcare personnel vaccination summary data via NHSN beginning with the 2014-2015 influenza season.  Detailed operational guidance, training, and other information for this reporting are available at NHSN ASC Surveillance for Healthcare Personnel Vaccination.

If your facility is already enrolled in NHSN, e.g. because your state requires your facility to report surgical site infections, it does not have to be re-enrolled.  Your NHSN Facility Administrator may simply activate the Healthcare Personnel Safety Component in NHSN.

Step 1: Training and Preparation


Print and follow detailed checklist [PDF - 370 KB] June 2015 to ensure successful and efficient enrollment.

Complete the Healthcare Personnel Safety Component [PDF - 3 MB] training.
