摘要

Background

The introduction of disease-modifying therapies (DMTs) for Alzheimer’s disease has prompted major changes in diagnostic pathways, referral processes, and service coordination in dementia care. Japan, as an early adopter of DMTs within a nationally coordinated dementia-care framework, offers an opportunity to examine how health service structures respond to these changes. This study explored health service–related support needs emerging across the DMT pathway, focusing on patient and informal caregiver experiences, with complementary perspectives from service providers.

Methods

A qualitative study was conducted using semi-structured interviews with 48 participants, including nine patients who underwent DMT eligibility assessment, seven informal caregivers, 11 physicians, four nurses, five clinical psychologists, five social workers, and seven community-based dementia support providers. Data were analyzed using the Framework Method, an applied qualitative approach suitable for health services research. Patients’ and caregivers’ accounts were treated as the primary analytic focus, while provider perspectives were used to contextualize system-level factors influencing care delivery.

Results

Three interrelated themes were identified. First, informational support needs reflected inequitable access to trustworthy information, difficulties in sustaining understanding of complex medical explanations, and a lack of structured opportunities to revisit information over time, particularly during transitions such as ineligibility, treatment discontinuation, or completion. Second, psychosocial support needs were closely shaped by service processes, including stigma-related experiences across clinical and social contexts, family-related tensions around treatment decisions, fluctuating expectations regarding treatment effects, and limited support for adjustment when DMT was no longer an option. Third, systemic and collaborative support needs highlighted fragmented roles between primary care and DMT-designated institutions, unclear referral and handover pathways, insufficient psychosocial care capacity, and weak integration between DMT delivery systems and existing dementia-care services.

Conclusions

The implementation of DMTs has amplified pre-existing gaps in dementia care systems, revealing previously underrecognized structural vulnerabilities across informational, psychosocial, and systemic domains. Findings indicate that DMTs should be embedded within coordinated care pathways that ensure continuity of information provision, access to psychosocial support, and clear allocation of follow-up responsibility regardless of treatment eligibility. Aligning pharmacological innovation with health service design is essential to support equitable, continuous, and person-centered dementia care.
