What specific compounding activities fall under USP 797 guidelines?
USP 797 governs the compounding of sterile preparations, encompassing any procedure where drugs or nutrients are combined, altered, or packaged to create a sterile medication. This includes preparing intravenous solutions, ophthalmic drops, irrigations, and other medications intended to be sterile when administered to patients.
USP 797 provides comprehensive guidelines designed to prevent harm, including death, to patients resulting from: microbial contamination (non-sterility), excessive bacterial endotoxins, variability in intended strength of correct ingredients, unintended chemical and physical contaminants, and use of ingredients of inappropriate quality in compounded sterile preparations (CSPs). The standards dictate environmental controls, personnel training, cleaning and disinfection procedures, and the proper use of equipment to maintain sterility and minimize the risk of contamination during the compounding process. They also specify requirements for storage and beyond-use dating of compounded sterile preparations. The scope of USP 797 extends to various settings, including pharmacies (both hospital and community), home infusion centers, and other healthcare facilities where sterile compounding takes place. Adherence to these guidelines is crucial for ensuring patient safety and maintaining the integrity of compounded sterile medications. It is essential to recognize that failure to adhere to USP 797 can have severe consequences, making thorough understanding and meticulous implementation of the guidelines critical for all personnel involved in sterile compounding.Does USP 797 address the storage of compounded sterile preparations?
Yes, USP 797 comprehensively addresses the storage of compounded sterile preparations (CSPs), outlining specific requirements for temperature, light, and environmental controls to maintain sterility and prevent degradation.
USP 797 provides detailed guidelines for storage based on the CSP's risk level (immediate-use, low-risk, medium-risk, and high-risk) and assigned beyond-use date (BUD). These guidelines specify acceptable temperature ranges for both refrigerated and room temperature storage, ensuring the CSP remains stable and safe for its intended use. For instance, refrigerated storage typically requires temperatures between 2°C and 8°C, while controlled room temperature is usually defined as 20°C to 25°C. Maintaining proper documentation of storage temperatures through continuous monitoring is also a key requirement to demonstrate compliance. Beyond temperature, USP 797 emphasizes the importance of protecting CSPs from light and other environmental factors that could compromise their integrity. Appropriate packaging and storage containers that shield CSPs from light exposure are recommended. Furthermore, the standard mandates that CSPs be stored in a clean and organized manner to prevent contamination and ensure proper identification. Proper storage not only preserves the sterility of the CSP but also its chemical stability, preventing the formation of toxic degradation products. Which is an example of what USP 797 covers? Proper personnel training on aseptic technique.What aspects of personnel training are covered by USP 797?
USP 797 covers comprehensive personnel training related to sterile compounding, encompassing areas like aseptic technique, garbing procedures, hand hygiene, cleaning and disinfection, proper use of equipment, understanding of standard operating procedures (SOPs), and principles of pharmaceutical calculations and sterile compounding. This training ensures personnel possess the necessary knowledge and skills to prepare sterile preparations safely and effectively, minimizing the risk of contamination and ensuring patient safety.
USP 797 emphasizes that training must be both initial and ongoing, with documented competency evaluations. The frequency of evaluations depends on the risk level of the compounding performed (low, medium, or high). These evaluations assess the personnel's practical skills and theoretical understanding, ensuring they maintain proficiency in critical areas. Furthermore, training programs need to be tailored to the specific tasks performed by each individual. For example, personnel preparing hazardous drugs require additional training on handling and disposal procedures according to USP 800, which works in conjunction with USP 797. Specific areas of competency covered in USP 797 training include visual inspection of sterile preparations, proper use of laminar airflow workbenches (LAFWs) or compounding aseptic isolators (CAIs), cleaning and disinfection procedures, and proper documentation. Training should also cover identifying and reporting potential issues or deviations from established procedures. Successful completion of training requires not only demonstrated knowledge but also consistent performance in simulated and actual compounding scenarios, as evidenced by passing both written and practical assessments. An example of what USP 797 training covers is:- Proper hand hygiene techniques to minimize contamination
Is environmental monitoring a component that USP 797 covers?
Yes, environmental monitoring is a crucial component covered by USP 797. It mandates regular testing of the compounding environment to ensure that air quality, surface cleanliness, and personnel practices meet specific standards, thereby minimizing the risk of contamination in compounded sterile preparations (CSPs).
USP 797 sets specific requirements for environmental monitoring, including viable air sampling, surface sampling, and personnel gloved fingertip sampling. Viable air sampling is performed to assess the level of airborne microorganisms in the compounding environment. Surface sampling evaluates the effectiveness of cleaning and disinfection procedures by detecting microbial contamination on critical surfaces. Gloved fingertip sampling assesses the competency of compounding personnel in maintaining aseptic technique. These monitoring activities are not merely suggested; they are required. The frequency and locations for environmental sampling are defined within USP 797 and may vary depending on the classification of the compounding area (e.g., ISO Class 5, ISO Class 7, ISO Class 8). Regular environmental monitoring provides data that can be used to identify trends, evaluate the effectiveness of cleaning and disinfection procedures, and implement corrective actions when contamination levels exceed acceptable limits. Therefore, it plays a vital role in maintaining a safe and sterile compounding environment.Does USP 797 include guidelines for verifying prescriptions prior to compounding?
While USP 797 does not explicitly detail step-by-step instructions for prescription verification, it emphasizes the importance of confirming the accuracy and appropriateness of each prescription before compounding sterile preparations (CSPs). It covers elements relating to proper documentation, checking calculations, and ensuring the CSP is suitable for the intended patient.
USP 797 focuses primarily on the processes, procedures, and quality standards designed to prevent harm, including death, to patients that could result from: microbial contamination (non-sterility), excessive bacterial endotoxins, variability in intended strength of correct ingredients, unintended chemical and physical contaminants, and incorrect quality of ingredients in CSPs. Therefore, the standard highlights the need for a robust system to ensure prescription accuracy as a fundamental pre-compounding step. This includes verifying ingredient selection, dosage calculations, route of administration, stability, and compatibility information, all of which are critical components in ensuring patient safety. One example of what USP 797 covers is establishing personnel training and competency requirements. It states that all personnel involved in compounding must be adequately trained and evaluated to ensure they possess the necessary knowledge and skills to perform their duties correctly. This training includes aseptic technique, calculations, proper use of equipment, and understanding of sterile compounding principles. Regular assessment of compounding personnel helps to prevent errors and maintain a high level of quality in CSPs. This implicitly promotes accurate prescription interpretation as part of the compounding process.What documentation requirements are addressed within USP 797?

These requirements primarily focus on policies and procedures, personnel training and competency, facility and equipment maintenance, compounding process validation, and the master formulation and compounding records for each CSP prepared.
USP 797 mandates that pharmacies maintain detailed written policies and procedures covering all aspects of sterile compounding. This includes standard operating procedures (SOPs) for personnel hygiene, garbing, cleaning and disinfection, equipment operation, compounding techniques, quality control, and handling hazardous drugs, if applicable. These SOPs must be regularly reviewed and updated to reflect current best practices and regulatory changes. Furthermore, the standard emphasizes the need for documented training programs that cover both didactic and practical aspects of sterile compounding, with regular competency assessments to ensure that personnel maintain the necessary skills and knowledge. Beyond personnel and process documentation, USP 797 also emphasizes meticulous record-keeping for facility and equipment maintenance. This includes documenting cleaning and disinfection schedules, calibration of equipment like balances and autoclaves, and environmental monitoring results. Compounding records, which include master formulation records and compounding logs, must be meticulously maintained for each CSP. These records provide a complete audit trail, detailing the ingredients used, the compounding process, quality control testing performed, and the personnel involved in each step. This documentation is vital for identifying potential errors, tracking product recalls, and demonstrating compliance with the standard's requirements.Does USP 797 provide standards for cleaning and disinfecting compounding areas?
Yes, USP 797 provides comprehensive standards for cleaning and disinfecting compounding areas, which are crucial for maintaining a sterile environment and preventing contamination of compounded sterile preparations (CSPs).
USP 797 outlines specific requirements for cleaning and disinfecting various surfaces within compounding environments, including primary engineering controls (PECs) such as laminar airflow workbenches (LAFWs) and compounding aseptic isolators (CAIs), as well as secondary engineering controls (SECs) like cleanrooms and anterooms. These standards address the frequency of cleaning, the types of cleaning and disinfecting agents that should be used, and the proper techniques for applying these agents. The goal is to minimize the bioburden (the number of microorganisms) in the compounding environment, reducing the risk of CSP contamination and, ultimately, patient harm. The standard mandates a tiered approach to cleaning and disinfection, with more critical areas requiring more frequent and rigorous cleaning. For example, PECs must be cleaned and disinfected more frequently than SECs. The use of sporicidal agents is also required at regular intervals to eliminate bacterial spores, which are highly resistant to standard disinfectants. Detailed written procedures for cleaning and disinfection must be established and followed, and personnel must be properly trained and evaluated on their cleaning techniques to ensure compliance with USP 797 standards. One example of what USP 797 covers includes explicit instructions on the proper technique for cleaning PECs. It emphasizes cleaning from top to bottom and back to front, using overlapping strokes with a lint-free wipe saturated with the appropriate cleaning or disinfecting agent. The standard also specifies the contact time required for the disinfectant to be effective, which is the amount of time the disinfectant must remain wet on the surface to kill microorganisms. Furthermore, it dictates that surfaces should be allowed to air dry completely before compounding activities resume.Hopefully, that gives you a clearer idea of the scope of USP 797!
