What Happens After a Patient Leaves the Hospital?
Why the most important care event may occur after the patient leaves the hospital — and how independent practices can gain visibility into transitions of care.
Key Takeaways
- Historically, practices often did not know when their patients were hospitalized until the patient called the office.
- ADT notifications and Health Information Exchanges now enable real-time visibility into admissions, discharges, and transfers.
- Better transition visibility supports timely follow-up, medication reconciliation, and care coordination.
- Effective transition management improves quality scores, reduces readmissions, and strengthens value-based care performance.
- Independent practices can access this infrastructure through CIN participation without building it internally.

Why This Matters
A patient is admitted to the hospital.
Medications are adjusted. Tests are performed. Specialists are consulted. After several days, the patient is discharged with instructions to follow up with their primary care physician within seven days.
Here is the question that has historically been difficult for independent practices to answer: does the practice even know this happened?
For decades, the answer was often no — unless the patient called to make an appointment.
The Historic Gap in Transition Visibility
Before health information exchanges and electronic notifications, practices relied on patients to communicate hospitalization events.
This created several problems:
- Patients might not remember to call.
- Patients might not understand the importance of timely follow-up.
- Patients might lack transportation, childcare, or the ability to schedule during office hours.
- The practice might not receive discharge summaries or medication lists from the hospital.
As a result, high-risk patients could go weeks or months without follow-up — and the primary care practice would have no visibility into the gap.
What Changes With ADT Notifications
ADT stands for Admission, Discharge, Transfer. These are electronic notifications sent when a patient experiences a transition in care.
When a practice participates in a health information exchange or ADT network, the practice receives real-time alerts when patients are:
- Admitted to a hospital
- Transferred between facilities
- Discharged to home or another setting
This changes the workflow from reactive to proactive.
Instead of waiting for the patient to call, the practice can reach out within days of discharge — scheduling follow-up appointments, reconciling medications, and addressing any issues that arose during the hospital stay.
Why Transitions of Care Matter for Performance
The period after a hospitalization is high-risk.
Patients may be on new medications. They may have new diagnoses. They may have questions about discharge instructions. They may experience complications.
Timely follow-up reduces:
- Readmission rates
- Emergency department utilization
- Medication errors
- Preventable complications
And it improves:
- Quality scores
- Patient satisfaction
- Value-based care performance
- Care coordination metrics
Real-World Examples
Consider these scenarios:
Without ADT notifications: A patient with congestive heart failure is discharged Friday evening. By Monday, the patient is experiencing shortness of breath but does not call the doctor. By Wednesday, the patient is back in the emergency department. The primary care practice learns about all of this weeks later — when a utilization report arrives.
With ADT notifications: A patient with congestive heart failure is discharged Friday evening. Monday morning, a care coordinator sees the discharge notification and calls the patient. An appointment is scheduled for Tuesday. Medications are reviewed. The care plan is adjusted. The patient stays home.
The clinical care may be similar. The outcome is fundamentally different — because the practice knew what happened.
How These Gaps Are Being Closed
Regional health information exchanges like GRAChIE connect hospitals, practices, and other healthcare organizations across a geographic area. When a patient is admitted or discharged from any participating facility, the patient's primary care practice can receive a notification.
This infrastructure was not available to most independent practices a decade ago. Today, through CIN participation and HIE partnerships, practices can access the same transition visibility that large health systems have.
How PHN Supports Independent Practices
PHN helps independent practices gain visibility into patient transitions through partnerships with health information exchanges like GRAChIE, ADT notification networks, and care coordination initiatives.
When practices receive real-time information about hospital admissions and discharges, they can follow up proactively — scheduling appointments, reconciling medications, and ensuring patients receive the care they need after leaving the hospital.
This infrastructure supports better patient outcomes, stronger quality performance, and more effective participation in value-based care programs — all without the practice needing to build these capabilities internally.
Questions to Consider
- Do we know when our patients are admitted to the hospital?
- How do we currently learn about hospital discharges?
- What is our follow-up rate after hospitalization?
- Do we participate in a health information exchange or ADT network?
- How much time passes between a hospital discharge and our first follow-up contact?
- What would change if we had real-time visibility into patient transitions?
The Bottom Line
For decades, independent practices operated in the dark when patients entered the hospital. The most important care event — a hospitalization — was often invisible to the physician responsible for ongoing care.
Today, health information exchanges, ADT notifications, and care coordination infrastructure are closing that gap. Practices that participate in these networks gain visibility into the full patient journey — and the ability to intervene when it matters most.
The most important care event may occur after the patient leaves the hospital. The question is whether the practice knows it happened.
