abstract = {Digital short cognitive tests administered by medical
assistants (MAs) in general practitioners' (GPs) practices
have great potential for the timely identification of
patients with dementia, because they can lead to targeted
specialist referrals or to immediate reassurance of patients
regarding their perceived concerns. However, integration of
this testing approach into clinical practice requires good
usability for the test itself, especially for cognitively
impaired older adults.In this implementation study, the
digital version of the Montreal Cognitive Assessment (MoCA)
Duo was conducted by MAs in general practice. We tested if
the interaction with the test is associated with usability
problems for the patients and aimed to find additional
relevant constructs that should be considered for the
potential implementation of such digital tests into clinical
practice. We focused the study on subjective success,
usability, and workload as well as their association with
the result of the cognitive test to assess whether the MoCA
Duo can be implemented into general practice.In total, 10
GPs took part in the study. Within their practices, 299 GP
patients (aged 51-97 years) with cognitive concerns
completed the MoCA Duo administered by MAs. Subsequently,
patients and MAs completed digital questionnaires regarding
the interaction with the app. Usability was measured using
the adapted System Usability Scale, and perceived workload
using the National Aeronautics and Space Administration Task
Load Index. For the perceived workload, we included an
assessment of the patient by the MA. Results of the MoCA Duo
were supplied to the GPs for their consultation with the
patient.The results indicated good usability for the MoCA
Duo. Self-assessment by the patients indicated that $64\%$
(191/299) could perform in the test to the best of their
ability, affected by their MoCA score. We found significant
higher usability ratings by patients with better MoCA scores
as well as by younger patients. Furthermore, the perceived
workload showed overall medium workload. We found
significant correlations between the subjective perceived
workload of the patients and the assessment by MAs.
Self-assessments as well as assessments by the MAs were
significantly influenced by the MoCA scores and the age of
the participants.The results indicate good usability of the
digital MoCA within the sample, supporting the idea that the
resulting scores are adequate to assess cognitive status
without dependence on technological affinity. Furthermore,
the results highlight the relevance of heterogenous samples
for comparable evaluation studies, based on the significant
effect of cognitive status and age on usability and
workload.},
