NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
The development of an iPad based App to support clinical and research assessment of cognition in dementia: ACEmobile.
Background:
Cognitive screening is common practice in efforts to identify Alzheimer’s dementia in the early stages. The need for reliable and accurate assessment is critical, at this stage, to avoid distress or missed opportunities to support people with developing health needs. Administrator errors are observed to be both significant and common when clinicians deliver cognitive screening tools in clinical contexts, often as a result of complicated rules and the need for mental arithmetic. The Addenbrooke’s Cognitive Examination-III is one of the most used cognitive screening tools in the UK, observed to be prone to such user errors.
Objective:
We aimed to develop and release a computerized cognitive screening support tool for clinicians who use the Addenbrooke’s Cognitive Examination-III to screen for dementia.
Methods:
We undertook an innovation pathways approach, including problem identification, feasibility assessment, design and implementation. This project required numerous stages of consideration to meet data protection and NHS standards for implementation, this process is detailed.
Results:
Clinicians were provided an iPad based app (ACEmobile) via iTunes, which draws on usability research to standardize user behavior – thus standardizing the assessment of cognitive impairment alongside automated scoring. Results include continued use after three years in the market, registration from over 1,100 clinical users and the consented collection of over 4,300 dementia assessments to support further research into the development of ACE-III and ACEmobile.
Conclusions:
ACEmobile has demonstrated itself as a clinical tool which continues to support a large number of clinicians and large scale research projects. The focus on usability has added value to its predecessor (ACE-III) in that the clinician’s assessment is now supported to be standardized. Feedback relating to ACEmobile has been unanimously positive and reflects these strengths.
