The Impact of the EDIFY Program at Tan Tock Seng Hospital on Reducing Unnecessary Hospital Admissions for Frail Seniors
Abstract
The global aging population has intensified the demand for innovative healthcare models to manage the needs of vulnerable elderly patients. Singapore’s Tan Tock Seng Hospital (TTSH) has pioneered the Emergency Department Interventions for Frailty (EDIFY) program, a geriatric care pathway designed to divert frail seniors from acute hospital wards to home or non-acute settings. This paper examines EDIFY’s structure, outcomes, and implications for healthcare systems. By analyzing data from TTSH’s 2025–2026 implementation, the program averted 723 unnecessary hospital admissions, reduced collective hospital days by 4,000, and mitigated risks such as delirium and functional decline. The findings underscore the efficacy of patient-centered, community-based care in addressing geriatric frailty while alleviating hospital resource strain. This study contributes to the discourse on reimagining healthcare delivery for aging populations.
- Introduction
1.1 Context and Rationale
By 2030, one in five Singaporeans will be aged 65 and above, with frailty a leading contributor to hospital admissions (Ministry of Health, Singapore, 2022). Acute hospitalization for older adults, particularly those over 85, is associated with iatrogenic complications including delirium, falls, and functional decline (Henderson et al., 2018). The 2025–2026 EDIFY program at Tan Tock Seng Hospital (TTSH) exemplifies a paradigm shift in geriatric care, prioritizing non-hospital settings for appropriate cases. This paper evaluates EDIFY’s success in reducing unnecessary admissions and its broader implications for healthcare policy.
1.2 Research Objectives
Assess the effectiveness of EDIFY in diverting frail seniors from acute hospitalization.
Analyze the clinical and systemic benefits of community-based care.
Discuss lessons for scaling similar programs in aging societies.
- Literature Review
2.1 Geriatric Care Models
Home-based care and short-stay wards are increasingly recognized for their role in managing acute frailty (Inouye et al., 2014). Studies show that non-hospital settings reduce complications and hospital readmissions while aligning with patient preferences (Cole et al., 2020). The “frailty pathway” concept, as implemented in EDIFY, integrates rapid triage, risk assessment, and tailored care plans.
2.2 Challenges in Senior Healthcare
Hospitalization for elderly patients often disrupts social and physical environments, exacerbating frailty (Gill et al., 2017). The scarcity of acute care beds in aging societies further emphasizes the need for alternatives that preserve functional independence.
- Methodology
3.1 Program Structure: The EDIFY Model
EDIFY operates within TTSH’s emergency department (ED), led by geriatric consultant Dr. Bao Minfang. Key components include:
Rapid Frailty Assessment: Nurses like Ameera Hanim Zainalabidin conduct on-site evaluations of vital signs, mobility (e.g., edema checks), and cognitive status.
Care Pathway Options: Patients are directed to:
Home Care via TTSH@Home (e.g., Mr. Chia Oh Chang received post-ED monitoring at home).
Short-Stay Wards: For observation or medication management.
Rehabilitation Wards: For patients requiring skilled therapy but not acute care.
Post-Discharge Follow-Up: Multidisciplinary teams ensure continuity, reducing 72-hour readmission risks.
3.2 Data Collection
Quantitative Metrics: Admissions averted (723 in 2025–2026 vs. 191 in 2024), average days saved (1.6–8.5 days per patient), and collective bed-day reduction (4,000 days).
Qualitative Insights: Patient and caregiver interviews (data not included in public reports).
Comparative Analysis: Outcomes vs. traditional care pathways.
- Results
4.1 Clinical and Operational Outcomes
Admission Reduction: A 277% increase in seniors diverted from acute wards.
Hospitalization Avoidance: Collectively, 4,000 fewer inpatient days.
Functional Stability: No 72-hour readmissions for 723 patients, indicating safe care transitions.
Demographics: 95% of beneficiaries were aged 85 and above, minimizing exposure to hospital environments.
4.2 Systemic Benefits
Resource Allocation: Frees up acute beds for critical cases.
Cost Efficiency: Lower expenses for home-based interventions versus inpatient stays.
Cultural Acceptance: Growing patient/family trust in non-hospital care, particularly in multicultural Singapore. - Discussion
5.1 Effectiveness of the EDIFY Model
EDIFY aligns with global “hospital at home” initiatives, demonstrating that structured community care is both feasible and safe for frail seniors (Bosco et al., 2022). The program’s success hinges on:
Rapid Decision-Making: ED staff trained in geriatric triage.
Integrated Care Teams: Collaboration between nurses, social workers, and rehab specialists.
Technology Support: Home monitoring tools (e.g., vital sign tracking via mobile devices).
5.2 Implications for Healthcare Systems
Scalability: Replication in other high-income democracies with aging populations (e.g., Japan, South Korea).
Policy Shifts: Incentives for home-based care and retraining ED staff in geriatric assessment.
Public Perception: Challenging the default assumption that hospitalization is always necessary for seniors.
5.3 Limitations and Challenges
Patient Eligibility: The program is suited for low-acuity cases; complex conditions require acute care.
Resource Intensity: Requires robust infrastructure for home visits (e.g., TTSH@Home’s logistics).
Cultural Barriers: In regions where hospitals are seen as essential for elderly care, acceptance may lag.
- Conclusion
TTSH’s EDIFY program offers a transformative approach to geriatric care, effectively balancing patient safety with system efficiency. By averting 723 unnecessary admissions and 4,000 inpatient days in 2025–2026, the model provides a blueprint for aging societies to reduce hospital strain while prioritizing individualized care. Future research should explore EDIFY’s long-term sustainability and adaptation in diverse cultural contexts. As Singapore’s population ages, initiatives like EDIFY will be pivotal in reshaping healthcare delivery toward resilience and inclusivity.
