Evaluation of the pragmatic implementation of a digital platform for Chinese caregivers of older adults with chronic diseases.

Background: Informal caregivers of older adults with serious health conditions, particularly stroke, dementia, and fractures, often experience substantial caregiving stress. Online platforms may offer an accessible and effective means of supporting caregivers and reducing stress. Objective: This study aimed to evaluate the effectiveness of a newly developed online platform in reducing caregiver stress and enhancing caregiver preparedness and competence. It also examined factors associated with platform use, as well as user satisfaction and engagement. Methods: A longitudinal open-trial design was employed, with assessments conducted at baseline, 3-month follow-up, and 15-month follow-up. Primary outcomes included caregiver stress, preparedness, and competence. User profiles were examined by comparing characteristics between users and non-users of the platform. User satisfaction and engagement were also assessed. Results: Of the 287 caregivers, 61% used the online platform. Compared with non-users, users showed a significant reduction in caregiving stress and greater improvements in caregiver competence, while no significant difference was found in caregiver preparedness. Users were more likely to be younger, employed full-time, have upper secondary education or above, report a monthly household income of HK$25,000 or higher, and have no chronic illness. At the 15-month follow-up, users reported high levels of satisfaction with the platform. Conclusions: The online platform effectively reduced caregiver stress and improved caregiver competence, with high user satisfaction. Further enhancements, such as increased multimedia content on practical caregiving preparation, may be needed to improve caregiver preparedness outcomes.
