CADD® administration sets with Flow Stop free-flow protection manufactured by Smiths Medical ASD – risk of under-infusion

All devices with an expiration date on or before 31 March 2021 are at risk of under-infusing so we advise users to undertake a risk assessment before using them. (MDA/2016/006)


  • Identify users of the CADD administration sets with Flow Stop and with the product re-order numbers stated in the Field Safety Notice (FSN).
  • Ensure that all healthcare users receive the manufacturer’s FSN and that they understand the problem.
  • Healthcare providers should assess the risks and benefits associated with the use of these devices for each individual patient when administering therapies where accuracy is critical e.g. cytotoxics, antibiotics and sedation.
  • If necessary, Smiths Medical can supply sets without free-flow protection as an alternative, until production levels of unaffected devices can meet demand. Contact Smiths Medical to obtain these devices.
  • Report any adverse incidents involving these devices to the MHRA.

The administration sets have the potential to under-infuse by up to 13.4% (this includes the manufacturer’s accuracy level of 6%, referenced in the CADD Ambulatory Infusion Pump Operator’s Manual). The sets are used for a variety of infusion therapies e.g. chemotherapy, sedation, cardiology, nutritional therapy etc. Therefore, the potential health consequences are varied and will depend on the patient and therapy involved.
