The accuracy of an ACD can be determined in various ways to ensure that the correct quantities of nutrients, electrolytes, or other nutritional components are delivered to the final infusion container. An air dryer or disposable nonshedding towels are used to dry hands and arms after washing.

Before their sterilization, plastic, glass, and metal devices are tightly wrapped in low particle shedding paper or fabrics, or sealed in envelopes that prevent poststerilization microbial penetration. Positive sterility test results should prompt a rapid and systematic investigation of aseptic technique, environmental control, and other sterility assurance controls to identify sources of contamination and correct problems in the methods or processes.

Additional procedures may also be essential for certain products, devices, or techniques. Compounding personnel must ascertain that selected filters will achieve sterilization of the particular CSPs being sterilized.

Work surfaces near the DCCA in the buffer or clean area are cleaned in a similar manner, including counter tops and supply carts. This test is completed without interruption within an ISO Class 5 air quality environment see Table 1. The compounding process requires unusually long duration, such as that required to complete dissolution or homogeneous mixing. Reporting and evaluation of results.

CSPs are rarely subjected to the extensive scientific testing required for determination of expiration dates for commercially manufactures drug products. When products are not distributed promptly after preparation, a predistribution inspection is conducted to ensure that a CSP with defects, such as precipitation, cloudiness, and leakage, which may develop between the time of release and the time of distribution, is not released.

In conjunction with those factors, the Low, Medium and High microbial contamination risk levels were determined based on the following:. A sufficiently increasing trend in cfu counts over time must prompt a re-evaluation of the adequacy of cleaning procedures, operational procedures, and air filtration efficiency within the sterile compounding location.

Compounding personnel who fail written tests, or whose media-fill test vials result in gross microbial colonization, must be immediately re-instructed and re-evaluated by expert compounding personnel to assure correction of all aseptic practice deficiencies.

Written procedures outlining required equipment calibration, annual maintenance, monitoring for proper function, controlled procedures for use of the equipment and specified time frames for these activities are established and followed.

Only the furniture, equipment, supplies, and other goods required for the tasks to be performed may be brought into this room, and they should be nonpermeable, nonshedding, and resistant to disinfectants. The contamination reduction conditions and procedures in this section include LAFWs being located within buffer or clean-room areas that maintain at least an ISO Class 8 see Table 1.

This includes storage in environments inferior to ISO Class 5 of opened or partially used packages of manufactured sterile products that lack guideline beyond use dating preservatives. Media-fill test procedure performed at least annually for each person.

The degree of error or inaccuracy would be dependent on the extent of differences between the CSP's characteristics such as composition, concentration of ingredients, fill volume, or container type and material and the characteristics of the products from which stability data or information are to be extrapolated.

Nonsterile ingredients are incorporated or a nonsterile device is employed before terminal sterilization.
