Overview

_____

“Describes conditions and best practices to prevent critical harm to patients, which can be attributed to contaminated or improperly compounded sterile preparations (CSPs).”

The outlined standards apply to all persons who prepare CSPs. This also includes the areas in which CSPs are prepared which may include: pharmacies, treatment clinics, hospitals, healthcare institutions, etc.)

Cleaning & Disinfecting Pharmacy Controlled Environments

_____

The preparation of CSPs is to be complemented with equally maintained sterility and a minimized introduction of particulate matter.”

“Environmental contact is one of the core sources of microbial contamination of CSPs.” While USP Chapter <797> provides best practices and minimum safety standards, Clean Air Essentials, offer the highest standard of cleaning and disinfecting products for compounding personnel preparing CSPs, who can be confident in knowing they are maintaining sterility and cleanliness to the compounding area.

Some of the sterile compounding duties include:

• Antiseptic Hand Cleansing and Disinfecting of Non-sterile compounding services Maintain sterility of CSPs in ISO Class 5
• Selection of appropriate protective garb
• Maintain sterility of CSPs in ISO Class 5
• Identify, weigh, and measuring of ingredients

It is important to recognize the contamination categories for CSPs, notably for their 3 levels of risk (low, medium and high) which can vary from harmful to life-threatening. While it is the responsibility of compounding personnel to be aware of the potential risks to the integrity of CSPs. It is also important to note that they are also responsible for the application of quality assurance practices, cleaning products and usage frequency. Proper product selection is important and should be done carefully.

	Routine Disinfecting consistently minimizes microbial surface contamination.	Note: Facilities with ISO Class 5 may have an increased standardized process for cleaning.
	Spot Check 1 (Personnel): Visual confirmation that all compounding personnel are wearing the appropriate PPE.	Review: All ingredients are correctly identified for compounding.
	Spot Check 2 (CSPs):  Visual confirmation that there is an absence of leakage from bags, vials and proper labelling.

Apply the P-E-C Cleaning Method:

	P	Proper selection and application of sterile wipes provided by Clean Air Essentials
	E	“East-to-West” single-direction cleaning to ensure full disinfecting coverage.
	C	Complete cleaning Hard to Reach Surfaces first, before cleaning large surfaces of the PEC *Wipe gloved hands and supplies with Sterile Isopropyl Alcohol 70%

Anteroom and the Buffer Room:

_____

Clean Air Essentials Guideline: It is important to separate the hardware supplies used for hazardous compounding and non-hazardous areas.

Isolators:

_____

Minimum Cleaning Frequency:

Daily

	Clean and decontaminate your unit before and after operation using Clorox Fuzion and/or Sterile IPA 70% How often should Isolator Sleeves be changed? 3 Months for Hazardous Compounding 6 Months for Sterile Compounding *Note: that the interval may be shorter for heavier use

Ceilings and Walls:

• Page 16 of the USP <797> indicates that “In the buffer or clean area, ante-area, and segregated compounding area, walls, ceilings, and shelving shall be cleaned and disinfected monthly.”

Cleaning Method: Eyes Up, Eyes Down (Top to Bottom)

	Prioritize cleaning ceilings first and work your way down. Be sure to clean irregular surfaces by hand with a dry wipe including air returns, outlets, shelving (Sterile Dry Wipes) and Clorox Fuzion.
	For walls, apply the East-to-West single-direction cleaning to ensure full disinfecting coverage.
	Ensure site protocols and SOPs are followed correctly.

Floors:

• Page 15 of the USP <797> dictates that “Floors in the buffer or clean area, ante-area, and segregated compounding area are cleaned by mopping with a cleaning and disinfecting agent once daily at a time when no aseptic operations are in progress.”

It is essential to be mindful of the following:

• Cleaning Materials Our sterile wipes or wiper rolls are recommended for cleaning.
• ‍*Note: Cleaning tools should be treated as single-use only. ‍
• Floor Cleaning Disinfectants: “When the surface to be disinfected has heavy soiling, a cleaning step is recommended prior to the application of the disinfectant.”
• Storage: Cleaning supplies used should be dedicated to that area, exclusively and not used in combination (i.e.) buffer or clean, ante and compounding areas.
• *Note: Removal of supplies from areas should be for proper disposal purposes, only.

Cleaning Method: “Far Out”

	Begin cleaning at the farthest corner of the room, mopping backwards towards the door of entry.
	Ensure to mop using the Essential-S Pattern, allowing solutions to settle for maximum disinfecting coverage.
