Sterile Compounding USP 797 Aseptic Technique

Key Elements of Aseptic Simulation Design

Aseptic simulations are designed to closely replicate compounding environments, ensuring personnel meet the rigorous standards set by USP 797. These simulations not only test technical skills but also assess how effectively individuals can maintain sterility in real-world scenarios. Here's a closer look at the key components of these simulations.

Creating Realistic Compounding Scenarios

A successful aseptic simulation mirrors the complexity of actual compounding workflows. This means accounting for factors like the number of components, the level of manipulation required, and the inclusion of non-sterile ingredients. Simulations should also span across low-, medium-, and high-risk preparations, as outlined by USP 797. By doing so, they align with the standard's emphasis on accurate risk stratification. Incorporating realistic challenges ensures the simulation reflects the pressures and demands personnel face during their daily tasks.

Media Fill Testing Basics

At the heart of aseptic simulations lies media fill testing, a critical method for evaluating aseptic technique. This process uses a microbiological growth medium, such as Tryptic Soy Broth (TSB), to mimic compounding procedures and detect any microbial contamination introduced during the process.

During a media fill test, standard materials are replaced with the growth medium, which is then incubated for 14 days at temperatures between 20–35°C (68°F to 95°F). Any visible microbial growth signals contamination and a failed test, while clear samples indicate proper aseptic technique. USP 797 specifies testing frequency based on risk level: annually for low- and medium-risk preparations, and twice a year for high-risk preparations. New personnel must also pass an initial assessment before handling sterile preparations. To ensure accuracy, these simulations should use the same materials, containers (like vials), and methods (such as syringes) employed in daily operations.

Room Conditions and Personnel Variables

The effectiveness of a simulation also depends on its ability to replicate real-world environmental and human factors. To do this, simulations should mimic the actual compounding environment as closely as possible. Introducing situational variables - such as additional staff, operational distractions, equipment malfunctions, or urgent preparation requests - can help evaluate how well personnel maintain aseptic technique under challenging conditions.

How to Perform Media Fill Simulations

This section breaks down the process of conducting media fill simulations, which are essential for assessing aseptic techniques. To ensure reliable results, the process must follow a structured approach that includes setup, execution, and evaluation, all in alignment with USP 797 guidelines.

Setting Up the Simulation

The key to a successful media fill simulation starts with selecting the right materials and creating realistic and challenging conditions. Sterile fluid culture media, such as soybean casein digest medium (SCDM) or tryptic soy broth, are used in place of the actual components used in sterile compounding procedures. These media should be packaged in forms - like bags, ampules, or vials - that closely resemble those used in daily operations.

For high-risk compounding scenarios, the process should begin with nonsterile media powder, followed by sterilization. This approach mirrors the most complex procedures performed in the pharmacy, allowing staff to demonstrate their ability to handle nonsterile components while maintaining sterility.

While commercial media-fill kits are available, they may not always reflect the actual procedures used in your pharmacy. Instead, purchasing individual sterile media components can provide a more accurate simulation. If working with nonsterile powder, always follow the manufacturer's instructions carefully. Avoid diluting the media with sterile water or saline unless specifically instructed, as this can weaken the medium and compromise its ability to support microbial growth.

Every step of the simulation should be documented thoroughly, including details about the media used, lot numbers, expiration dates, and certificates of analysis.

Running the Media Fill Process

Once the setup is complete, the next step is executing the media fill simulation using standard compounding procedures. Start with proper hand hygiene, appropriate garbing, and gloved-hand fingertip sampling to establish baseline conditions. The simulation should replicate the most complex manipulative steps involved in sterile compounding.

Timing and conditions are critical for effective testing. Conduct media-fill simulations under challenging conditions, such as at the end of a shift when staff may be fatigued. For new personnel, initial validation tests should be especially rigorous, lasting 2–3 hours and incorporating multiple components and intricate steps.

During the simulation, personnel must follow the same procedures they use with actual pharmaceutical ingredients, including using identical syringes, vials, and manipulation techniques. Maintaining proper cleanroom protocols - such as monitoring air pressure, temperature, and personnel flow - is essential to ensure the validity of the test results.

Reviewing and Recording Results

After completing the simulation, the results must be carefully evaluated to confirm compliance with USP 797. Media units should be stored at 68°F to 95°F (20° to 35°C) for 14 days, or for at least 7 days at each temperature if two temperature settings are used - starting with the lower range.

Inspections of the media-fill units should be conducted by someone other than the preparer. Reviews should take place at least on day 7 and day 14, though daily inspections are strongly advised. Any visible signs of contamination, such as turbidity (cloudiness), strings, or clumps, indicate a failed test.

A clear medium doesn’t automatically mean success. Observing the participant’s adherence to aseptic procedures during the simulation is just as important.

All findings should be documented in detail, including participant information, simulation parameters, environmental conditions, and both visual and behavioral observations. This thorough documentation ensures compliance with USP 797 and supports ongoing competency in aseptic techniques.

Additionally, growth promotion testing is necessary when using double-strength media or when working with nonsterile powder, as per manufacturer instructions. This testing should be conducted by an accredited microbiology lab following USP 71 standards to confirm the media’s ability to support microbial growth in case of contamination.

Personnel Testing and Documentation Requirements

USP 797 requires all compounding personnel to undergo both initial and regular competency testing, with thorough records kept to ensure compliance. These records must detail every assessment, including the testing methods used and the results, as part of maintaining regulatory adherence.

Measuring Aseptic Technique Performance

Evaluating aseptic technique accurately is a key part of both testing and documentation. Competency assessments should cover several components: gloved fingertip testing, media fill simulations, and surface sampling. If any of these elements are not successfully completed, the individual fails the aseptic manipulation assessment.

Testing Schedule and Best Practices

Initial competency testing in aseptic manipulation is mandatory for all personnel involved in Category 1, Category 2, and Category 3 compounding. The recommended testing intervals are as follows:
