Why should compounding pharmacies continuously monitor particles?

Hospital pharmacies are unique because of the critical role they play in maintaining patient health and safety. Pharmacies that perform compounded sterile preparations (CSPs), in particular, must meet specific clean room standards to ensure sterile conditions are maintained. While there are many established environmental requirements in these spaces, some pharmacy managers are choosing to go the extra mile in exchange for added peace of mind.

Are Hospital Pharmacies Moving Toward Clean Room Standards?

The regulation language in U.S. Pharmacopeia Standard 797 (USP 797) has long been the guiding principle for cleanliness in hospital pharmacies that treat cancer patients with compounding sterile preparations (CSPs). For airflow in these special rooms, USP 797 outlines how spaces are to be pressurized, and what are permissible parts per million (PPM) particle counts.

What is a PID loop?


In HVAC systems, various motors and devices need to be controlled with modulated signals to turn damper actuators and hydronic reheat valves. Most controllers in the industry do this using specific and standard logic, called a Proportional Integral Derivative (PID) controller, or PID Loop. PID is mathematical logic that provides these three functions as parameters that can be tuned, so devices function accurately and optimally.

How do we know that hospitals are safe?

Hospitals and outpatient facilities serve a critical need in global communities. They provide emergency care for the sick, but we also rely on them as a safe zone for treating communicable diseases and keeping the public at-large safe. But how can we know for certain that a hospital is clean and safe, and that we won’t get sick from something another ill patient has carried in?

What is a Vivarium?

To most people, the term “vivarium” conjures up the image of a small fish tank-like glass box where a pet rat or gecko lives. While this is not incorrect, vivariums in biomedical research facilities are a bit more robust than what you might see in a high school science lab.

Vivarium Defined

Vivariums are enclosed areas designed to provide a stable environment for animals and plants for observation or scientific research. Often, vivariums contain a portion of an ecosystem for a particular species with controlled environmental conditions on a smaller scale. A vivarium you would find in an academic research setting contains multiple racks of various sizes depending on the species it contains.

Why does The Joint Commission care about room pressurization?

The Joint Commission (TJC) is a non-profit organization that evaluates and accredits healthcare organizations in the United States, ensuring that hospitals and other medical facilities are providing safe and high-quality care to their patients. Inspections occur every three years and take between 2 to 3 days. In most jurisdictions, Medicare and Medicaid funding is contingent on accreditation by TJC.

One of the most important standards scored in a Joint Commission evaluation is room pressurization (EC.02.05.01). According to ASHRAE Standard 170 (used specifically by TJC as its standard), over 60 different areas of concern within a facility need to be either positively or negatively pressured. Pressurization in these spaces is tested simply by holding a tissue at the bottom of a door and determining whether the tissue is blown back away or sucked towards the gap.

Why you should get rid of your air flow indicator

Many environments within a health care facility require pressure monitoring in order to protect patient health. Even spaces like hospital linen closets require some sort of indicator of positive or negative differential pressure.

How can Employees Contaminate a Clean Environment?

It is commonly known that gowning procedures and air flow requirements are essential to maintaining a sterile clean room environment. Workers and operators don’t realize how crucial employee training is and the enormous impact employees have with the sanitation of the cleanroom. Unfortunately, humans are considered to be the biggest threat to the cleanroom and the largest source for contaminants, accounting for 75% to 80% of particles and microbes generated in a room. Understanding how personnel create particles and microbes or bring in contaminants, can help structure proper employee training, greatly bringing down the risk for clean environment contamination.
