Improving practice using action research: resolving the problem of kinking with non-metal cannulae

Area of Science:

• Palliative Care
• Medical Device Safety
• Infusion Therapy

Background:

• Needlestick injuries were reported with early infusion devices.
• Teflon cannulae initially reduced injuries but caused kinking issues with new syringe drivers.

Purpose of the Study:

• To investigate and resolve recurrent occlusion alarms caused by cannula kinking.
• To identify and evidence a safer alternative infusion device for hospice care.

Main Methods:

• Action research methodology was employed.
• Investigation of device failures and patient/staff safety concerns.
• Sourcing and evidencing a satisfactory alternative infusion device.

Main Results:

• Teflon cannulae kinking led to delayed medication delivery and required cannula re-siting.
• The introduction of McKinley T34 syringe drivers exacerbated cannula kinking issues.
• A satisfactory alternative device was successfully sourced and evidenced.

Conclusions:

• Continuous subcutaneous infusion device selection is critical for patient safety and effective medication delivery.
• Addressing device-related issues through action research improves hospice practice.
• Proactive problem-solving ensures the safeguarding of both healthcare staff and patients.
