BACKGROUND: Reminiscence therapy (RT) is the most common non-pharmacological treatment for dementia care. The therapy stimulates the senses to evoke memories having the potential to reduce Behavioral and Psychological Symptoms of Dementia (BPSD). Digital RT, such as web-based reminiscence therapy (WBRT), has the potential to support dementia care and reduce the caregiving burden. AIMS: This study aimed to explore healthcare professionals (HCPs) perceptions of utilizing WBRT in institutionalized settings to support persons with dementia during the COVID-19 pandemic. METHODS: A qualitative phenomenological descriptive study was adopted and guided by Graham's Knowledge to Action framework. Online training on the use of WBRT was conducted, followed by interviews with HCPs. RESULTS: Four major themes were identified on the potential use of WBRT in dementia care, including usability and efficacy, impact on caregiving, capability of reducing BPSD, and. feasibility during COVID-19 social distancing. DISCUSSION: This study recognized the potential use of WBRT to support the person with dementia during the pandemic in institutionalized settings. CONCLUSION: The knowledge generated from this study will guide the future application of WBRT to support dementia care in diverse healthcare settings.
