The Next Generation of Medication Safety Clinical Insights - Smart Design
With an estimated 90% of all hospital in-patients receiving intravenous (IV) medication, fluids and blood products via infusion pumps1
, it is unsurprising that errors occur. Whilst the arrival of
smart pumps, drug error reduction software (DERS) and drug libraries have all played their part in reducing the risk, IV infusions are still associated with 54% of all adverse drug events, 56% of medication errors, and 61% of serious and life-threatening errors2
are particularly prone to mistakes3 study finding 67% had documented errors4
. IV infusions delivered in the intensive care unit (ICU) , with one observational . Problems with
pump programming, and competing work demands are cited as underlying reasons2
beginning of the road towards error free IV infusions.
At BD, our focus is to develop technology and systems for the medication management pathway that support efficient workflows and patient safety, helping to build positive working environments for healthcare professionals.
We spoke to Richard Bailey, part of the design team at BD, to find out more about the development of BD neXus.
“We had three main goals with the design of the BD neXus Infusion Pump: simplification, performance and connection.”
Simplification We designed one syringe pump and one volumetric pump for ease of use in all care areas, keeping the user interface the same to help minimise the training needed. We have kept them small and lightweight to help improve stackability and bedside management.
Performance Our customers told us loud and clear not to compromise on performance, so simplification maintains performance through pre-programmed infusions; load dose, TPN, multi-step and handover mode.
Connection We wanted to enable nurses to better connect to their patients by having the right infusion data, in the right place, at the right time, helping them make informed decisions about patient care.
l . “Smart” technology is therefore just the
The objective was to design a device with clinicians, for clinicians. Richard explained how the design team conducted interviews with over 500 key stakeholders to better understand their infusion needs. “We ran more than 100 practical live sessions with nurses, where they performed tasks on BD neXus, including more than 600,000 key presses, gloved, and double gloved, to help stress test the touch screen”.
“As we listened to nurses before and during the design process, we heard many times that ease of use is vital. In fact, one nurse coined the phrase ‘keep it simple and safe,’ or KISS. That really resonated with our team.”
Richard highlighted several key design aspects that are incorporated into the BD neXus pump:
l
Home Button This simplifies access to the most-used functions. Similar to a smartphone home button, it provides easy access to the four common features: ml/hr, Guardrails™, infusion modes, and optional modes. But it is also a way for the user to find their way back to the main infusion screen with just one press.
Chevrons and Fast Track Data Entry Streamlining data entry can help limit risk and reduce errors. The authors of the CHI+MED guidelines for number entry interface design5
identified that users tend to look at the numeric keypad
as they are inputting the numbers, rather than the display. That makes them more prone to number entry errors.
l Use of chevrons to adjust values
Richard told us “We kept the chevrons as our principal way for data entry. Data inputs are managed by pressing and holding the appropriate chevrons to increase and decrease the data value.”
l Fast Track entry mode
“With Fast Track entry mode, the user can enter higher values. It’s just as quick as a numeric keypad, but without the need to enter a decimal point. The user is able to keep their line of sight on the desired output on the screen, which we believe will help minimise programming errors.”
