In relation to air sampling for Category 1 and 2 CSPs, how often should this be performed?

The frequency of air sampling for sterile compounding, particularly for Category 1 and 2 compounded sterile preparations (CSPs), is aligned with standard guidelines that aim to ensure the quality and safety of sterile products. In accordance with regulations, air sampling should be done every 6 months for facilities compounding Category 1 and 2 CSPs. This interval is established to monitor the microbial quality of the environment where sterile compounding occurs, providing a critical check on potential contamination risks that could compromise patient safety.

This 6-month timeframe balances the need for assurance of quality with practical considerations, ensuring that any potential issues can be identified and remedied with adequate frequency. It is also important to note that more frequent monitoring may be advised in areas of concern or if any deviations from established protocols occur, but under normal circumstances, the established guideline is every 6 months for these categories of CSPs.
