Understanding USP Chapter 797 Definitions: Key Terms in Sterile Compounding

Welcome to our article on USP Chapter 797 definitions! In this brief and easy-to-understand guide, we'll explain the essential terms used in sterile compounding. Whether you're a healthcare professional, patient, or simply curious about medication safety, these definitions will help you grasp the concepts used in ensuring the proper preparation and handling of sterile medications.

1. Aseptic Technique

The aseptic technique refers to the methods and procedures used to maintain a sterile environment during compounding to prevent contamination of medications. It involves practices like proper handwashing, wearing sterile gloves, and using sterile equipment to maintain a clean environment.

2. Beyond-Use Date (BUD)

The Beyond-Use Date is the date after which a compounded sterile preparation should not be used. It is determined based on factors like the sterility of ingredients used, the storage conditions, and the risk level of the compounded product.

3. Compounding

Compounding is the process of combining, mixing, or altering drugs and ingredients to create personalized medications for patients. It is often necessary when commercially available products are not suitable or available.

4. Critical Site

A critical site refers to the part of a sterile package or device that, if contaminated, could lead to the contamination of the compounded sterile preparation. For example, the rubber stopper on a vial is considered a critical site.

5. Low-Risk Level

Low-risk level compounding involves simple manipulations of sterile ingredients, usually requiring shorter preparation times. These preparations have a lower risk of contamination.

6. Medium-Risk Level

Medium-risk level compounding includes multiple small-volume sterile drug preparations, which may involve more complex manipulations than low-risk preparations.

7. High-Risk Level

High-risk level compounding involves preparations that are more susceptible to contamination due to exposure to non-sterile environments or extended storage periods. These preparations require the highest level of care and precautions.

8. Immediate-Use CSPs (IUSP)

Immediate-Use Compounded Sterile Preparations (IUSP) are medications prepared for administration within one hour of compounding. They are typically used in emergency situations and require aseptic technique.

9. Personnel Training and Competency

Personnel involved in sterile compounding must receive appropriate training to understand the procedures and potential challenges. Competency assessment ensures that they are proficient in performing their compounding responsibilities.

10. Quality Assurance

Quality assurance involves activities to ensure that compounded preparations meet the required standards for sterility, potency, and stability. Regular testing and monitoring help maintain the highest quality of sterile medications.

11. Risk Levels

Risk levels categorize compounded sterile preparations based on their potential for contamination and harm to patients. Low, medium, and high-risk levels dictate the necessary precautions during compounding.

12. Storage and Labeling

Proper storage and labeling of compounded medications are crucial to maintain their stability and prevent errors. Labels must include the Beyond-Use Date, medication name, strength, and storage conditions.

Conclusion

Understanding the key terms and definitions in USP Chapter 797 is essential for ensuring the safe compounding of sterile medications. Aseptic techniques, risk levels, and quality assurance play crucial roles in protecting patient health. By adhering to these definitions, healthcare professionals can provide patients with high-quality and contamination-free medications, promoting better patient outcomes and medication safety.
