Aim
To analyse the effectiveness, efficiency and satisfaction in usability of a technological tool dedicated to
health and self-care in patients with multimorbidity in primary care.
Material and methods
Cross-sectional observational descriptive study of usability within the framework of the clinical trial
in Primary Care in Madrid of the TeNDER project (NCT05681065). Patients over 60 years of age with
one or more chronic diseases were included. The main study variable was usability effectiveness,
which was determined as the degree of completion and the total number of errors per task. Five tasks
based on real case scenarios were evaluated. Sociodemographic variables and technology affinity
and satisfaction were collected. Descriptive analysis was performed and factors associated with task
completion were estimated using a logistic regression model.
Results
In all, 12% (30/250) of the included patients agreed to participate in the usability study. The usability
effectiveness was 89.3% (134/150 tasks completed). In all, 66.7% of patients (20/30) completed all
tasks and 56.7% (17/30) required personalised help on at least one of the tasks. In multivariate analysis,
education level acted as a facilitating factor (OR 1.79 [0.47–6.83]) for independent task completion. The
median time to complete all tasks was 296 seconds (IQR 210–397) and the median satisfaction was
55 (IQR 45–62.5) out of 100.
Conclusion
Task-based usability effectiveness was high. The moderate usability satisfaction scores and the
dispersion of usability efficiency scores suggest that other factors may be interfering. No association
has been described between multimorbidity and the usability results of this technological tool.
