San Diego—Automated peritoneal dialysis (APD), a therapy for patients with end-stage renal disease (ESRD), is currently underutilized, due perhaps to the perception that patients may not be able to manage treatment setups, a skill required with that treatment modality. Some barriers to uptake of APD many be reduced via improvements to cycler technology that may futher simplify therapy procedures for patients.
Catherine Firanek, RN, CNN, MBA, and colleagues recently conducted a study of 30 individuals with ESRD who were randomized into two groups using a cycler with a patient-centric interface with advanced technology in development and a conventional cycler each day. The study aimed to determine whether an enhanced user experience was associated with use of a cycler-embedded patient-centric interface compared with a conventional APD cycler.
The researchers reported results of the study during a poster session at Kidney Week 2015. The poster was titled Impact of a Patient-Centric Automated Peritoneal Dialysis User-Interface on Operator Learning and Confidence.
Study participants evaluated cyclers on two non-consecutive days using a different cycler each day. Each participant received a brief orientation, setup task, training session, break, followed by setup task and questionnaire. Fisher’s exact, Mann-Whitney, and Exact binomial tests were used to analyze study results.
For reduced reliance on printed instructions, the cycler with the patient-centric user interface and advanced technology (in development) scored better that the conventional cycler (P<.0001). Following training, there were fewer deviations committed by patients on the cycler in development compared with the conventional cycler (2 of 19 steps vs 14 of 19, respectively) (P=.004), including disinfecting hands (P=.02) and line handling (P=.01). Further, participants were more confident that they set up the cycler according to specifications (P=.043).
The new cycler scored higher in overall preference; it was rated easier to learn (P=.005) and easier to use (P=.03). Compared to the conventional cycler, users felt more confident about using the new cycler at home (P=.001).
“A cycler with embedded, patient-centric interface was rated higher in terms of overall reliance on instructions, task competency, ease of use and learning, preferences, and overall confidence of using the cyclers. These findings indicate that APD operator learning and confidence can be enhanced with a patient-centric user-interface,” the researchers said.
