Effectiveness of a Digital Activity Platform for Informal and Formal Caregivers in Long-Term Care Facilities (EngageLTCdigit)

Background Population aging and the increasing number of older people with cognitive and physical impairments present major challenges for long-term care facilities. At the same time, shortages of nursing and care staff, as well as a decline in informal support, contribute to increasing demands on caregivers. In this context, innovative approaches are needed to support caregivers and promote high-quality person-centred care.Person-centred care focuses on the individual needs, preferences, abilities, and life experiences of residents. Digital technologies may support caregivers in planning and delivering individualized and meaningful activities while enhancing residents' social participation.

Study Objectives The primary objective of this study is to investigate the effects of using the digital engagement platform on person-centred care. In addition, the study will examine caregivers' cultural competence, the collection of residents' biographical information, the frequency and duration of platform use, and users' experiences with the platform. Adverse events occurring during the study period will also be documented.

Intervention This study evaluates the effectiveness of the digital engagement platform "PflegeZeit" in residential long-term care facilities. The platform is used on tablets or other digital devices and provides individualized engagement activities. The intervention is based on three core components: the integration of biographical information and reminiscence, cognitive stimulation, and physical activation. By combining these components, the platform aims to support caregivers in implementing individualized and person-centred engagement activities in everyday care practice.

Control Group The control group will not receive access to the digital engagement platform and will continue routine care practices within their respective long-term care facilities. No additional digital support tools will be provided as part of the study.

Study Population The study targets both formal caregivers (e.g., nursing and care staff) and informal caregivers (e.g., family members, volunteers, or civilian service participants) who provide care and support to residents in residential long-term care facilities.

Defined inclusion and exclusion criteria will be applied to ensure that participants represent the intended target population. Detailed eligibility criteria are provided in the corresponding section of the study registration.

Study Design The study is designed as a multicentre, open-label, quasi-experimental pre-post study with a control group.

Participating long-term care facilities will be assigned to either the intervention group or the control group prior to study initiation. Facilities in the intervention group will implement the digital engagement platform as part of routine care, whereas facilities in the control group will continue providing usual care without the platform. Participants will be observed over a period of 12 weeks. Data collection will take place at four time points: baseline and after 4, 8, and 12 weeks.

Sample Size and Recruitment Participating caregivers will be recruited from four to eight long-term care facilities. The sample size is based on the primary outcome, the group-by-time interaction in the Person-Centred Practice Inventory for Staff (PCPI-S), and was determined using an a priori sample size calculation conducted with G*Power 3.1. The calculation indicated a required sample size of 36 participants. To account for an anticipated dropout rate of up to 15%, a target sample size of 42 caregivers will be recruited. Of these, 21 participants will be allocated to the intervention group and 21 participants to the control group.

Statistical Analysis Data analysis will be conducted according to a predefined statistical analysis plan. Descriptive statistical methods will be used to characterize the study population and study variables. Changes over time and differences between the intervention and control groups will be evaluated using linear mixed-effects models. These analyses will account for both repeated measurements and the clustered structure of the data at the facility level.

Potential Benefits and Risks The use of digital health applications in long-term care has the potential to support caregivers in the delivery of person-centred care. Previous research suggests that digital interventions may positively influence communication, caregivers' job satisfaction, and the social participation of residents. This study aims to provide further evidence regarding the potential benefits of a digital engagement platform in residential long-term care settings.

No specific risks or disadvantages associated with participation in the study or the use of the digital engagement platform are known for caregivers. The platform is used within routine care activities. Any additional burden is limited to the time required for platform use and participation in study-related data collection. Adverse events will be systematically monitored and documented throughout the study.

Expected Contribution The findings of this study are expected to contribute to the evidence base for digital support interventions in long-term care. The results may help identify effective strategies to support caregivers, strengthen person-centred care, and further develop the quality of care for residents in residential long-term care facilities
