If you monitor every load, only one load is recalled. More frequent monitoring reduces the number of loads that need to be recalled. A recall should also be done when any indicators or monitors suggest a sterilization process failure. For example, if a load is released and upon review of the record keeping information it is determined that the mechanical monitors used for equipment control did not read correctly, recall that load even if the biological indicator is negative. A load should be recalled if any of the monitoring controls suggest a problem.
Speed is the most important factor when dealing with a recall.
The more you run a biological indicator the faster the readout results are obtained, the sooner the medical devices can be recalled, and the less chance a patient becomes involved. The decision tree is an excellent tool for determining what steps to take during a recall procedure. Always assume that a positive biological indicator is the result of a sterilization process failure and recall the load. Do not wait until the complete subculturing results are available, and never assume the result is a false positive because you could not determine immediately the reasons for the process failure. Speed is important, so recall medical devices immediately to reduce the chances that a patient may contact a nonsterile medical device and develop an infection.
