What category would a CSP fall into if it is prepared under the least controlled conditions?

Category 1 CSPs are those that are prepared under the least controlled conditions, which signifies a higher risk of contamination and potential adverse outcomes. This category is designated for compounded sterile preparations that do not meet the defined standards for cleanliness and environmental controls typically expected in more regulated conditions.

The conditions for Category 1 compounding often include scenarios where sterile preparations are made using techniques that do not fully comply with quality standards, such as in an uncontrolled environment, or when minimal sterility measures are taken. These preparations are generally considered to present a higher risk for microbial contamination and, therefore, they require immediate use, often being administered directly to patients without further storage.

The other categories, while also addressing sterile compounding practices, pertain to varying degrees of control and safety measures in preparation. They outline practices that fall under stricter regulations and are used for preparations that are intended to be stored for a longer duration. Therefore, being aware that Category 1 signifies the least stringent controls is essential for understanding the varying levels of risk associated with compounded sterile preparations.
