Encounter Notification Service

What is ENS?

Encounter Notification ServiceĀ® (ENSĀ®), powered by Audacious Inquiry (Ai), is a low-complexity and high value population health management tool. ENS technology is easily deployable and relies on basic healthcare data in the Admission, Discharge and Transfer (ADT) message.

ENS offers a more efficient and cost-effective way to coordinate care. Ai has deployed ENS for customers in Maryland, the District of Columbia, Delaware, Pennsylvania, Utah, West Virginia, and Florida. Over 18.5 million patients are subscribed via ENS, and over 2.4 million notifications are sent each month.

How Can ENS Help You?

Improve Patient Satisfaction
ENS notifications improve communications between care team managers and patients, leading to greater engagement and satisfaction.
Avoid Unnecessary Readmissions
Knowing when, where, and why your patients are hospitalized provides an opportunity to intervene and avoid unnecessary readmissions.
New Revenue Opportunities
ENS notifications present an opportunity for providers to capture transitional care related revenue for Medicare patients.

How Does ENS Work?

  • ENS uses ADT messages that are already created within hospital systems.
  • Every time a real-time ADT message is received by ENS, the patient within the ADT is compared to the updated weekly eligibility file from TennCare and the auto-subscription list pre-loaded by hospitals into ENS.
  • If a patient match is found, a notification is generated and sent to TennCare (only for TennCare patients) and hospitals (if they have a relationship with that patient).
