7.015 Hand Hygiene: Practice observation of hand hygiene compliance via the use of a hand hygiene survey tool to be reviewed quarterly at the QAPI committee. (Chapter 10.14 Handwashing & Surgical Antisepsis) Continue infection control education through ongoing orientation to center staff routinely and annual mandatory in-service. Continue to promote hand hygiene awareness for patients and staff by means of educational materials placed throughout the center which references the CDC/WHO guidelines. Needle-stick Injuries: (Refer to Exposure Control Plan) Use of designated safety engineered needles for injections (safety glide needles for injection and autoguard IV catheters) and blood draw. New employee and annual clinical competency for injections will be provided to all staff. The staff will be trained yearly on OSHA, blood borne pathogens and PPE. 7.016 Hand Hygiene Quality in the ASCs: based on AORN (Association of periOperative Registered Nurses) Standards and guidelines Policy: All ASC staff, including physicians, nurses, and other healthcare workers, are required to perform hand hygiene before and after any direct contact with patients, before and after any procedure, and after any contact with potentially contaminated items or surfaces. Hand hygiene must be performed using either an alcohol-based hand rub or soap and water. The alcohol-based hand rub must contain at least 60% alcohol. Staff members must ensure that their hands are free of debris and visible dirt before performing hand hygiene. Hand hygiene must be performed for a minimum of 20 seconds, and hands must be dried thoroughly after washing. Staff members must be trained on proper hand hygiene techniques and will be educated on a regular basis to ensure compliance with this policy. All staff members must comply with this policy and demonstrate compliance during inspections by ASC management and regulatory agencies. Any staff member who fails to comply with this policy will be subject to disciplinary action. ASC management will monitor compliance with this policy through regular inspections and audits and will take appropriate action to address any noncompliance issues. The ASC will maintain records of staff compliance with this policy as part of its infection control program. The ASC will review and update this policy on an annual basis or more frequently as needed to ensure that it remains current with the latest guidelines and standards for hand hygiene quality.
