Improved usability of a multi-infusion setup using a centralized control interface: A task-based usability test

Abstract

The objective of this study was to assess the usability benefits of adding a bedside central control interface that controls all intravenous (IV) infusion pumps compared to the conventional individual control of multiple infusion pumps. Eighteen dedicated ICU nurses volunteered in a between-subjects task-based usability test. A newly developed central control interface was compared to conventional control of multiple infusion pumps in a simulated ICU setting. Task execution time, clicks, errors and questionnaire responses were evaluated. Overall the central control interface outperformed the conventional control in terms of fewer user actions (40±3 vs. 73±20 clicks, p<0.001) and fewer user errors (1±1 vs. 3±2 errors, p<0.05), with no difference in task execution times (421±108 vs. 406±119 seconds, not significant). Questionnaires indicated a significant preference for the central control interface. Despite being novice users of the central control interface, ICU nurses displayed improved performance with the central control interface compared to the conventional interface they were familiar with. We conclude that the new user interface has an overall better usability than the conventional interface.

Critical care information display approaches and design frameworks: A systematic review and meta-analysis

“…2 for an example) [46–55], (2) displays that integrated data from bedside devices and monitors (see Fig. 3) [56–61], (3) displays that integrated data for the purpose of antibiotic selection and management [62–64], and (4) displays that integrated information into a novel graphical presentation [65–68]. Display designers frequently described an intention to organize the information in more clinically meaningful ways, for example, by human body systems, medical concepts, or provider tasks.…”

Nurses’ Involvement in the Development and Usability Assessment of an Innovative Peripheral Intravenous Catheterisation Pack: A Mix-Method Study

“…Historically, while nurses provide a unique end-user-centric, patient-focused approach to medical device development, there is little evidence of their involvement during device development [ 37 ]. This continues to be true at present, especially in the fields of vascular access and infusion therapy, with only a few published cases concerning intravenous syringes and infusion pumps [ 38 , 39 , 40 , 41 , 42 ].…”

Exploring of Nurses’ Needs of New Design Intravenous System Device to Support Nursing Care Effectively

“…The result in table 3 also found that the majority of participants expected that the new design of the intravenous system device can be designed to stop automatically. A "This device must have a quality battery so that if the light turn of or when the patient delivered to the radiology room/ physiotherapy room it can still be used without electricity" Theme 4: Simplicity Category Easy to use Participant 13 said: "The device must be easily operated by new nurses without special training" Participant 8 said: "The device must be designed in a sophisticated yet simple way to operate" study stated that the infusion pump must have the ability to stop the infusion fluid that runs out automatically (Doesburg et al, 2017). Other nurses in this study expected that the new design of the device also to be able to monitor the remaining intravenous fluid automatically through the screen of the device.…”
