The 6008 CareSystem has been developed to simplify the extracorporeal circuit of the system through a disposable cassette, automate operation steps, and facilitate handling in comparison to its predecessor — the 5008 CorDiax. The present investigations were performed with the aim of evaluating usability, safety, and ergonomic aspects of the new therapy system.Methods: A time–motion study compared these two hemodialysis systems with video and time recording of handling steps required to prepare, operate, and dismantle a dialysis machine. The ergonomic burden on hands and finger joints was evaluated in a second study, again by video-recording the simulated operation of both dialysis systems.Results: The number of handling steps required for the 6008 CareSystem and critical contact points were reduced by 26% in comparison to the 5008 CorDiax for patients with arteriovenous fistula used for vascular access and by 22% for those with a catheter used for vascular access. Total process time was reduced by 2.83 and 2.57 minutes using fistulae and catheters for vascular access, respectively. The number of hand grips and finger and thumb presses was reduced by approximately 50% and required less strength to execute.Conclusion: The most recent hemodialysis system confirmed its ease of use and user safety through fewer handling steps and less physical burden on the user. Shorter operational time should enable more patient-focused care.Keywords: ergonomics, usability, hemodialysis equipment, safetyGründler UEkesbo ELöwe MGauly ADove Medical Pressarticleergonomicsusabilityhemodialysis equipmentsafetyMedical technologyR855-855.5ENMedical Devices: Evidence and Research, Vol Volume 14, Pp 379-387 (2021)
