Update on Mayo and FDA Tube Feeding Research

Testing

As we announced in the May/June issue of LifelineLetter, researchers at the Mayo Clinic in Rochester, Minnesota, and the Food and Drug Administration (FDA) began testing flow rates of enteral feeding tubes and connectors this summer. Flow testing of commercial tube feeding formulas was conducted on different size feeding tubes using both the current (“legacy”) connectors and the new ENFit® connectors. Mayo Clinic’s initial results were presented at the Oley annual conference in July; since then the flow rate testing has been nearly completed.


The researchers are moving on to other types of testing to learn more about the blenderized diets (homemade or prepackaged) that some home enteral nutrition (HEN) consumers choose to use instead of, or in addition to, standard commercial formulas. Researchers at Mayo Clinic and FDA have begun to perform tests that will characterize the amount of force required to administer some blends and formulas through different size tubing, using both legacy and ENFit syringes. For this testing, they are using blenderized diet recipes provided by Oley members and by Mayo Clinic, as well as commercially prepared and packaged blenderized formulas. For the purpose of this testing, Mayo Clinic and FDA researchers have created standardized mixing directions that they will follow to prepare the blends. They are also using different types of blenders to compare the effectiveness of the different blenders.


When complete, these tests will provide an independent review of the impact the new ENFit connector system has on the delivery of homemade blenderized diets as well as commercially produced standard and blenderized formulas. It will allow the stakeholders (caregivers, patients, clinicians, manufacturers) to understand consumers’ equipment needs—from blenders to tubes and connectors—and which practices will provide the greatest success for consumers using homemade blenderized diets with the ENFit connectors.

 

Survey of Home Enteral Nutrition Consumers

In addition Mayo Clinic conducted a nationwide survey of HEN consumers this fall to better understand home tube feeding practices. It is the first attempt to conduct a broad-based nationwide survey of HEN consumers. It was distributed by Mayo Clinic, the Oley Foundation, Feeding Tube Awareness Foundation, and several home care companies. While the vast majority of people filled out the survey online, an Oley volunteer was available to help the handful of people who preferred to complete the survey by phone. Oley also made a paper copy of the survey available upon request.


This comprehensive survey will increase our understanding of tube feeding practices, including the use of blenderized diets.


Information about the results of the testing and the survey is expected to come out after the first of the year.
