What risk level is assigned to multiple pooled sterile commercial preparations for either multiple patients or one patient multiple times?

The risk level assigned to multiple pooled sterile commercial preparations for either multiple patients or one patient multiple times is categorized as medium risk. This classification is grounded in the complexities and potential for contamination involved in the activity.

In medium-risk compounding, there is usually an increased chance of microbial or chemical contamination due to the nature of the procedures involved. For example, pooling sterile commercial preparations requires care to prevent contamination from the environment or during the manipulation of the products. The process often involves multiple steps, multiple preparations, or the integration of different sterile products, which can introduce more opportunities for errors or contamination compared to simpler procedures.

Additionally, the medium-risk level reflects practices where the compounded formulations are prepared in such a way that they need to be used within a specific time frame to ensure their safety and efficacy. This aspect is crucial when preparing medications intended for multiple patients or for an individual patient over an extended period, where sterility is paramount.
