12 practice guidelines for needleless connector best practice

Used widely in acute care, needleless connectors (NCs) are designed to ensure patient and healthcare worker safety1–3. 

Focus on risks to patient safety 

Catheter-related bloodstream infections (CRBSIs) 

CRBSIs are one of the most frequent, deadly and expensive complications of central venous catheters4. Central venous catheters have a higher risk of catheter-related infections than any other type of medical device4.

Occlusion 

Occlusion is one of the five most frequent reasons for peripheral IV catheter (PIVC) failure5. It can be caused by mechanical obstruction such as from kinking of the catheter, from catheter migration into a “dead-end” position within the vessel wall or tissue without frank infiltration/extravasation or from thrombosis of the catheter and/or surrounding vessel5. Blood reflux can also play a significant role in thrombotic catheter occlusion2. 

Incidence of occlusion ranges from 2.5% to 32.7%5 

Focus on risks to healthcare worker safety 

Needlestick injuries 

Needlestick injuries continue to affect healthcare workers (HCWs). Commonly affected populations are doctors, nurses and medical/nursing students. Studies have shown that of all occupational exposures, 35% occur among persons in training and 27% among experienced nurses6 

Underreporting is a problem with only 9–38% of healthcare workers declaring their injuries7. The occurrence of needlestick injuries is most frequent among HCWs having close clinical contact with patients or patient specimens7. 

Needleless connectors: an essential device in your vascular access toolkit 

NCs offer the possibility of connecting administration sets or syringes to vascular access devices (VADs) by eliminating the use of needles8. Along with needlestick injury prevention, these devices are also designed to help prevent IV catheter-related complications9. 

The International Nosocomial Infection Control Consortium (INICC) issued Care Bundles to Prevent Central and Peripheral Line-Related Bloodstream Infections9. 

To help prevent IV catheter-related complications9: 
  1. Use a luer-lock mechanism to ensure a secure junction when attaching the NC to a VAD or access site 
  2. Don’t use three-way stopcocks as IV connection devices 
  3. Disinfect NCs before inserting them into each VAD 
  4. Use aseptic technique when changing NCs 
  5. Only access NCs with a sterile device 
  6. Consider using an extension set between the IV line and NC to reduce line manipulations 
According to the 8th edition of the Infusion Therapy Standards of Practice, you should change needleless connectors8: 
  1. When they are removed for any reason 
  2. If blood or debris are found inside them 
  3. Before drawing blood samples for culturing from the VAD (which should be avoided when using CVADs because these samples are more likely to produce false positives) 
  4. If contamination occurs 
  5. According to your healthcare facility’s policies, procedures and/or practice guidelines 
  6. Per the manufacturers’ directions for use

Not all needleless connectors are alike 

In 2014, a peer-reviewed meta-analysis by Tabak et al. found that NCs should contain the following safety features3: 

  • A smooth, solid access surface that can be effectively disinfected 
  • A visible fluid path allowing HCWs to verify flushing 
  • A straight fluid path 
  • Minimal internal complexity 
  • No blood reflux  
  • The ability to flush with saline solution alone 

Needleless connectors: a preventative measure to help ensure patient and healthcare worker safety 

Needleless connectors for intravenous systems can help protect healthcare workers from needlestick injuries. They may reduce the risk of exposure to blood-borne pathogens8. Positive displacement technologies and devices help reduce blood reflux at disconnection, which may lead to catheter occlusions8 

Tabak et al. found a 63% reduction in the risk of central line-related bloodstream infections (CLABSIs) with the MaxPlus™ Clear Needleless Connector when compared to other NCs used with central venous catheters3 

Williams et al. found a 55.1% reduction in occlusions with the MaxZero™ Needleless Connector when compared to other NCs used with central venous catheters in their observational study2.
