Hospital care is designed to treat illness. But for older adults, it often creates a new problem: decline.

Research shows that up to 50% of seniors lose physical or cognitive function during a hospital stay, and the majority never recover it. At the same time, nearly 1 in 5 Medicare patients are readmitted within 30 days, with a large portion of those readmissions occurring within the first few days after discharge.

In this episode, we sit down with Dr. Joseph Flaherty, Regional Medical Director of Geriatrics at Envision Physician Services, to unpack what is actually happening inside hospitals and why well-intentioned care often accelerates frailty.

Dr. Flaherty has spent his career redesigning hospital systems for older adults, including developing Acute Care for the Elderly (ACE) Units and now leading efforts toward one of the first dedicated geriatric hospitals in the United States, set to open in Plano in 2027.

We explore the concept of hospital-acquired frailty, often described as the cascade of dependency, and why simple factors like immobility, medication use, and workflow constraints create downstream functional collapse.

This conversation goes beyond theory. Dr. Flaherty shares what works in practice, including his current model at Medical City Plano, where a dedicated geriatric unit prioritizes mobility, minimizes high-risk medications, and actively works to preserve independence during hospitalization.

Main points to deliver to audience:
-Why hospitals unintentionally cause decline.
-Hospital-acquired frailty and the cascade of dependency (multi-system decline)
-The critical role of mobility during hospitalization
-Medication-driven decline
-Real-world constraints inside hospitals and what a better model looks like

Practical take-aways for audience:
-Immobility is one of the biggest risks in healthcare
-Medication decisions have functional consequences
-Families and providers should advocate for function, not just treatment
-Shift toward prevention of loss of function before irreversible decline occurs.
