Needleless connectors (NC). They鈥檙e used a thousand times a day in healthcare facilities worldwide where these small devices can have a big impact.

NCs give access to the vascular system and were originally designed to cut down on the number of needlestick injuries. These days they鈥檙e described as the microbial gatekeeper of the Vascular Access Device¹. Since their introduction, they鈥檝e been shown to be associated with increased Catheter related blood stream infections (CR-BSI). They act as a perfect portal for microbes to get into the bloodstream with potentially devastating effect².

Small devices with big consequences

CR-BSI infections impact heavily both on patients and economics. It can mean up to 20 days of hospital stays, costing up to US$56,000 per patient³. Australian data shows on average patients stay in hospital for 16.8 days longer than those who don鈥檛 suffer this avoidable complication. In 2015鈥�16, 4,416 cases of CR-BSI were reported in public hospitals⁴, at an additional cost of AU$34,843 per episode⁵.

What鈥檚 the right disinfectant for NCs?

Healthcare professionals seem to be confused about which is the right disinfectant, as well as when and how to use it to decontaminate NCs and reduce the risk of CR-BSI. They are resorting to guesswork which doesn鈥檛 help.

What do the guidelines say?

International guidelines exist⁶ and these show via studies that using friction is effective, as well as allowing key parts to dry.

The Infusion Nurses Society recognises that NCs are 鈥減otential sites for intraluminal microbial contamination and require strict adherence to infection prevention practices鈥�⁷. Their advice includes the following:

• 鈥淧erform vigorous mechanical scrub for manual disinfection of the needleless connector prior to each VAD access and allow to dry鈥�
• 鈥淟ength of contact time for scrubbing and drying depends on design of needleless connectors and the properties of disinfecting agent鈥�

In the UK, the Royal College of Nursing guidance states: 鈥渋njection and access devices must be decontaminated using aseptic technique prior to accessing the device鈥�⁸.

Other National guidance states that 鈥渁ll injection and access sites should be decontaminated with 2% chlorhexidine gluconate in 70% alcohol. The solution should be applied with friction and allowed to dry, immediately before and after use鈥�⁹.

Australian guidelines also state: 鈥�Clean key parts 2% chlorhexidine/70% alcohol wipes is the application of choice鈥�¹⁰.

Methods of decontamination have also been studied and a new paper from a Brisbane-based research team has evaluated alcohol caps and alcohol swabs with and without Chlorhexidine, concluding that the optimal method of NC decontamination is 30 seconds with CHG swabs¹¹.

Clinell 2% Chlorhexidine in 70% Alcohol Wipes offer a successful solution

Clinell 2% Chlorhexidine in 70% Alcohol Wipes are the largest available measuring 190x105 mm. The larger size, made from non-woven material, makes it easier to manipulate where it鈥檚 being used. This cuts down on the risk of contamination from the clinician鈥檚 hands or fingers and supports Aseptic Non-Touch Technique (ANTT) practices.

The wipes are TGA registered for surface disinfection of non-invasive medical devices, as well as IV Access ports (hubs & connectors) amongst other things.

The wipes come with the combined support of Clinell鈥檚 Clinical Specialist nurses for training, which helps them to be implemented successfully. As with all new practices.

Clinell 2% Chlorhexidine in 70% Alcohol Wipes offer an excellent solution for those looking to adopt evidence-based practice in needleless connector decontamination.
