Automated patient monitoring that cut rehospitalizations by 52%
Across thousands of facilities, patient vitals were monitored by hand, so deterioration was caught late and readmissions climbed. We built an automated patient monitoring and clinical alerting system that reads live EHR data, watches vitals in real time, and sends physicians only the alerts that matter.

About the client
A major player in US healthcare, serving thousands of health systems, hospitals, ACOs, managed care providers, and LTPAC (long term and post acute care) facilities. They are dedicated to improving care and reducing costs while promoting interoperability between healthcare organizations, so providers can achieve better outcomes for their patients and raise the overall quality of care.
The challenge
Manual monitoring could not keep up with patient risk
The solution
An automated, EHR-integrated healthcare management system
We built a Healthcare Management System that removes the manual work from patient data collection and alerting. It integrates directly with existing EHR systems to collect patient data, including demographics and vitals, promptly and continuously, so decisions are made on live clinical data instead of stale snapshots.
At its core is a flexible Domain Specific Language (DSL): a dynamic, no-code rules engine for defining exactly when an alert should fire based on a patient's medical condition. It can evaluate a single vital or several vitals together, at a single moment or across a period of time, and it accommodates the different requirements of each healthcare organization and LTPAC facility without any code deployment.
When a rule is triggered, the system sends a clinical alert with recommendations to the physician in real time through a mobile app, so the right person acts on the right patient at the right moment.
The approach
How we delivered it
Putting the alert rules in each facility's hands, instead of routing every threshold change through engineering, is what let the system scale across thousands of very different care settings.
The results
A 52% drop in rehospitalizations and better care at lower cost
Our company has teamed up with Tark for almost seven years to collaborate on a variety of projects. They are exceptionally capable at understanding not only the business requirements, but the business itself. Beyond delivering functional software, they have consistently prioritized performance, user experience, and keeping our technology stack current, and we've been able to rely on their architectural recommendations.
In our experience, most firms we've engaged with have struggled to balance requirements, deadlines, performance, and usability. Tark is a clear exception.
