The Biggest Win: Vertical Fragmentation and the Patient Journey

Of all six levels in this series, vertical fragmentation — the gaps between levels of care, from primary care down through hospital, rehabilitation, and home — responds most dramatically to solved data fragmentation.

A Journey Through Levels of Care

Follow a single patient down through the system: primary care refers to a hospital; the hospital discharges to rehabilitation; rehabilitation hands off to home care. Each step used to depend on paperwork, phone calls, and hope. With shared records, referrals are visible to everyone in the chain, discharge plans travel with the patient automatically, and follow-up reminders trigger themselves rather than waiting on someone to remember.

The Evidence: Fewer Readmissions, Real Savings

This isn’t theoretical. A study across 38 healthcare organizations in an 11-county region of western New York found that patients whose records were accessed through the regional health information exchange were readmitted within 30 days at a rate of 5.1%, against 10.1% for patients whose data wasn’t accessed — roughly half the rate. The researchers estimated close to 48 avoided readmissions and about $605,000 in annual savings from that gap alone.

That’s what closing the vertical handoff with data looks like in a real system, not a projection.

Why Vertical Integration Responds Best to Data

The failure at this level is, for the most part, genuinely informational: the next provider in the chain often doesn’t know what happened at the last one. Fix the information gap and most of the vertical failure closes with it. It’s one of the few fragmentation types where data alone gets a system most of the way there — which is exactly why the gains show up so clearly in the numbers.

Quantifying gaps like this one — and the savings behind closing them — is exactly the kind of visibility VAO is built to provide.
