Microtest Labs Helps Manufacturers of Reusable Medical Devices Meet FDA Cleaning Validation Requirements

AGAWAM, MASS. — August 13, 2013 — Microtest Laboratories is employing new state-of-the-art technology to assist manufacturers of reusable medical devices ensure that they meet U.S. Food and Drug Administration (FDA) requirements for cleaning validations.

Many manufacturers of reusable medical devices only create a set of instructions on manual washing — although automatic washing is gaining popularity. But the FDA requires that manufacturers validate that all sets of cleaning instructions and meet the parameters indicated on a reusable medical device’s labeling.

Microtest Labs acquired a new Getinge 46 series automatic washer/disinfector — used to reprocess soiled reusable medical devices so they can be used again for subsequent procedures. The washer removes soil and performs a low level disinfection of reusable medical devices — thus removing the variability of manual reprocessing.

Technicians at Microtest Lab will use the new system to expand and supplement their consulting services with manufacturers. “By working with manufacturers to develop and validate a set of autowashing parameters, we are helping to ensure that their devices will be processed faster and more reproducible. This saves time and costs — and helps reduce the future possibility of a soiled device being used by a healthcare professional,” said Philip Nosel of Microtest Labs.

Based on its expertise, the company has recently published a management brief summarizing the FDA’s requirements for automatic washing cleaning validation and discussing the benefits of automatic washing. The brief, “Automatic Washer Validation for Medical Device: Are you in compliance?,” is available for download at http://microtestlabs.com/automatic-washer-validation.

New Scope of Reusable Medical Device Cleaning Validations is Examined in New White Paper from Microtest Laboratories

AGAWAM, MASS. – October 2, 2012 – The new scope of cleaning validations for the manufacturers of reusable medical devices is examined in a white paper available for download from http://www.microtestlabs.com/new-scope-cleaning-validation-paper.

“Cleaning validation for reusable medical devices is an important step in proving their safety. Available guidance documents now indicate that the traditional method of validating cleanliness, spore log reduction, will no longer be acceptable. Analytical assays capable of providing quantitative results will now be required instead,” writes white paper author Patrick Kenny, Manager of Analytical Services, Microtest Laboratories.

In the new white paper, “The New Scope of Reusable Medical Device Cleaning Validations,” Kenny notes that “although a new requirement for reusable medical devices, these tests are traditional analytical assays that are performed routinely on other types of samples.”

“An effective protocol and report that includes justifications for the test soil and assays chosen, as well as thorough documentation of all parameters used in the validation, will help ensure success for the device’s submission,” Kenny notes.

The paper discusses cleaning validation analytical assays as well as various methods and scenarios related to performing the validation. Recommendations are based on several key documents relating to reusable device cleaning validations that are either in draft or final form. They include AAMI document TIR30:2003, a comprehensive guide to medical device cleaning validations. TIR30 is currently in revision, and an updated version is scheduled for 2011 release.

Kenny holds a M.S. degree in Chemistry and has spent the past 13 years working in QC, R&D and manufacturing laboratories. At Microtest, Kenny leads the services group performing medical device and pharmaceutical analytical testing for companies worldwide.

Use Notebook Studies to Ensure Successful Reusable Device Cleaning Validations, Recommends Microtest Laboratories

AGAWAM, MASS. —August 14, 2012 — A new management brief from Microtest Laboratories recommends that medical device manufacturers use notebook studies to help ensure successful reusable device cleaning validations. The lab bases the advice on its performance of validations for various types of medical instruments over the years.

The brief discusses the document, “FDA Draft Guidance for Industry and Staff, Processing /Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling,” which was released in May 2011.

“Even though it’s labeled as a draft, experience has shown that most reusable device cleaning validations are being evaluated based on this document,” said Patrick Kenny, manager of analytical services at Microtest Laboratories — and author of the new brief titled, “Notebook Studies to Ensure Successful Reusable Device Cleaning Validations.”

Kenny’s brief focuses on areas of the FDA guidance document that are causing difficulties in cleaning validations, and demonstrates how pre-validation laboratory work can help save time and money. It also identifies areas that can cause issues during validations if they are not thoroughly addressed prior to initiating the protocol. These include:

  • The use of worst-case conditions
  • The switch from microbial-based assays to chemical-based assays
  • The determination of an acceptable residual level
  • The validation of a reusable device’s cleaning instructions

“The good news is that almost all of these issues can be eliminated with some up-front work,” Kenny said. “And this preparatory work can best be performed by notebook studies prior to initiating GLP studies. The information obtained in these relatively quick studies often saves significant time later in the filing process.”

“In short, we recommend the use of notebook studies prior to beginning the validation to eliminate as many unknowns as possible,” he said.
