Human-Centered Design of Mobile Health Applications for Older Adults: Systematic Review and Narrative Synthesis
ABSTRACT
Background:
The world is ageing. The number of older patients rises, and along with it comes the burden of non-communicable diseases both clinical and economic. Attempts with mobile health (mHealth) have been made to remedy the situation with promising outcomes. Researchers have adopted human-centred design (HCD) in mHealth creation to ensure those promises become reality.
Objective:
The aim of this systematic review is to explore existing literature to address how human-centred design should be used to create highly usable mHealth applications.
Methods:
A systematic review was conducted to seek studies of mHealth interventions aimed at older adults with their HCD process explained from the following databases: IEEE Xplore, MEDLINE via Ovid, PubMed, and Scopus. Two independent reviewers then assessed their eligibility: they must be written in English, include participants older than 60 years old, and report about mHealth applications and their HCD development from start to finish. The 2 reviewers continued to assess the included studies’ qualities using the Mixed Methods Appraisal Tools (MMAT). A narrative synthesis was then carried out and completed.
Results:
Eight studies passed the eligibility criteria: 5 were mixed methods studies, and 3 were case studies. Some studies were about the same mHealth projects with the total of 5 mHealth applications. The included studies differed in HCD goals, target groups, and details of their HCD methodologies. The HCD process was thematically explored in 4 steps through narrative synthesis according to International Standardisation Organisation (ISO) 9241-210: (1) understand and specify the context of use, (2) specify the user requirements, (3) produce design solutions to meet these requirements, and (4) evaluate the designs against requirements.
Conclusions:
Challenges and recommendations are summarised logically with structural order and time order based on Minto’s pyramid principle and ISO 9241-210. Findings show that existing literature in the subfield of HCD and mHealth for older adults is still limited. The quality of most included studies is also deemed inadequate as appraised by MMAT. The details of the sampling method are lacking. Also, objective and quantifiable goals of the system are not set, leading to failure in drawing a significant conclusion. More studies of HCD application on mHealth with measurable design goals and rigorous research strategy are warranted.
