9. What is the primary procedure performed at the ASC (i.e., what procedure type reflects the majority of procedures performed at the ASC)? Select only ONE bubble.

The infection control program

If the ASC does not have an explicit infection control program (15), a condition-level deficiency related to 42 CFR 416.51 must be cited.
If the ASC does not follow nationally recognized infection control guidelines (16), a deficiency related to 42 CFR 416.51(b) must be cited; depending on the scope of the lack of compliance with national guidelines, a condition-level citation may also be appropriate.
If the ASC cannot document that it considered and selected specific guidelines for use in its infection control program (16a), a deficiency related to 42 CFR 416.51(b) must be cited.
This is the case even if the ASC's infection control practices comply with generally accepted standards of practice/national guidelines.
If the ASC neither selected any nationally recognized guidelines nor complies with generally accepted infection control standards of practice, then the ASC should be cited for a condition-level deficiency related to 42 CFR 416.51.
If YES to (a), 16b. which nationally-recognized infection control guidelines the ASC has selected for its program. Select all that apply.
17. Does the ASC have a licensed health care professional qualified through training in infection control and designated to direct the ASC's infection control program? If the ASC cannot document that it has designated a qualified professional with training (not necessarily certification) in infection control to direct its infection control program, a deficiency related to 42 CFR 416.51(b)(1) must be cited.
Lack of a designated professional responsible for infection control should be considered for citation of a condition-level deficiency related to 42 CFR 416.51.
If YES, 17a. Is this person an ASC employee or an ASC contractor. Select only ONE bubble.
17b. Is this person certified in infection control (i.e., CIC)? Note: §416.50(b)(1) does not require that the individual be certified in infection control.
Infection identification and staff training

If the ASC does not have a documented identification system (18) for infections that may have been related to procedures performed at the ASC, a deficiency related to 42 CFR 416.51(b)(3) must be cited.
If the ASC does not have supporting documentation, a deficiency related to 42 CFR 416.51(b)(3) must be cited.
If the ASC does not have a reporting system (18c), a deficiency must be cited related to 42 CFR 416.51(b)(3).
CMS does not specify the means for reporting; generally this would be done by the State health agency.
19. Do staff members receive infection control training? If training is completely absent, then consideration should be given to condition-level citation in relation to 42 CFR 416.51, particularly when the ASC's practices fail to comply with infection control standards of practice.
19d. Indicate frequency of staff infection control training. Select all that apply.
If training is not provided to appropriate staff upon hire/granting of privileges, with some refresher training thereafter, a deficiency must by cited in relation to 42 CFR 416.51(b) and (b)(3).
