Modular cleanrooms can be designed as a single-pass cleanroom, a recirculating with air-chase walls and ceiling plenum, or as a hardwall partition for existing sterile environments.

On January 1, 2004 USP 797 regulations went into effect. These regulations are FDA enforceable and the FDA has indicated that it fully intends to do so.

USP 797 applies to healthcare personnel in all healthcare facilities where sterile preparations (CSP's) are compounded, stored, and dispensed, including community pharmacies, outsourcing pharmacies, physician practices, infusion clinics, surgical clinics, home care orgaizations, long-term care facilities and satellite pharmacies.

In order to be in compliance with the new rules, such institutions will needd to protect their products by utilizing a Laminar Airflow Workbench (LAFW's) within a cleanroom or , depending on requirements, a positive pressure barrier isolatior which takes the place of a cleanroom by providing cleanroom conditions within a contained workspace.

By January 2005, the Joint Commision on Accreditation of Healthcare Organizations (JCAHO) will require an action plan for each accredited healthcare organization that will bring the organization into compliance with USP 797 within a reasonable period of time.

Liberty's barrier isolator, pictured at the link above, isolates areas from various contamination sources including the volume of air surrounding the equipment and the space from ceiling to floor. A varrier isolator encompasses a much smaller area around the process allowing a small volume and proper airflow and totally removes workers containmation from the process.

Whether the decision is to install a cleanroom or opt for a barrier isolators, the primary goal is safety. Both systems have their benefits and drawbacks, but it is up to the individual pharmacy directors to make the best decision for their business, their personnel and their patients.
