Introduction
We incorporated patient feedback from human factors studies (HFS) in the patient-centric design and validation of ava®, an electromechanical device (e-Device) for self-injecting the anti-tumor necrosis factor certolizumab pegol (CZP).Methods
Healthcare professionals, caregivers, healthy volunteers, and patients with rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, or Crohn’s disease participated in 11 formative HFS to optimize the e-Device design through intended user feedback; nine studies involved simulated injections. Formative participant questionnaire feedback was collected following e-Device prototype handling. Validation HFS (one EU study and one US study) assessed the safe and effective setup and use of the e-Device using 22 predefined critical tasks. Task outcomes were categorized as “failures” if participants did not succeed within three attempts.Results
Two hundred eighty-three participants entered formative (163) and validation (120) HFS; 260 participants performed one or more simulated e-Device self-injections. Design changes following formative HFS included alterations to buttons and the graphical user interface screen. All validation HFS participants completed critical tasks necessary for CZP dose delivery, with minimal critical task failures (12 of 572 critical tasks, 2.1%, in the EU study, and 2 of 5310 critical tasks, less than 0.1%, in the US study).Conclusion
CZP e-Device development was guided by intended user feedback through HFS, ensuring the final design addressed patients’ needs. In both validation studies, participants successfully performed all critical tasks, demonstrating safe and effective e-Device self-injections.Funding

AbstractThis study explores the experiences of adult children as they transition their functionally and/or cognitively declining aging parents from independent living to supervised housing. A qualitative grounded theory approach was used to chronicle the experiences of adult children as their caregiving responsibilities intensified and their parents' health declined. Purposive, snowball sampling was used to enlist adult children (n = 16) who were in the process of transitioning an aging parent from an independent living situation to one providing assistance with everyday care and tasks. Semi-structured telephone interviews were conducted and designed to follow a pattern of increased frailty of the parent(s) and escalating involvement of the adult child. Two major themes emerged from the data: Changing places and everlasting love. Adult children began to intervene when cognitive or physical declines compromised the safety and well-being of the older adult and began to assume responsibility for day-to-day needs. As disabilities intensified, adult children relied on siblings, friends, social services, and health care providers to assist in planning and implementing caregiving responsibilities. Deep respect and abiding love of the aging parent(s) sustained the adult child throughout the caregiving experience. 相似文献
