Case Study

A Case Study in partnership with East Kent NHS Foundation Trust:

Faster Diagnosis, Greater Efficiency and Enhanced Patient Experience with Zio™ Service2-5 

Physician looking at computer

iRhythm partnered with East Kent NHS Foundation Trust, one of England's largest hospital trusts who were struggling to cope with a surge in cardiac monitoring demand.

Existing Holter monitoring methods were highly resource-intensive, requiring multiple patient visits and lengthy manual analysis causing breaches in the 18-week pathway and delays in identifying life threatening cardiac arrhythmia abnormalities.

 

The trust implemented the Zio™ XT Long-Term (14 day) Ambulatory Monitoring service, benefiting from the Direct-to-Patient Service and Electronic Health Record (EHR) integration.

Outcomes included

  • 100% reduction in outpatient fitting appointments vs. Holter2
  • 18 min time saving per patient through EHR integration3
  • 98% Zio service reports posted vs. 84% from Holter 

By prescribing Zio, patients get their results faster. This helps them move from uncertainty to action sooner. With Zio™ Service, hospitals ex­perience fewer repeat visits and less need for additional testing, freeing up valuable clinical time

The Zio™ service is a long-term continuous ambulatory cardiac monitoring service. It consists of the Zio™ XT that collects beat-to-beat ECG data and can be worn for up to 14 days; the Zio™ ECG.

Utilization Service (ZEUS) System deep learned algorithm which detects arrhythmias. The data is reviewed and curated by a team of Qualified ECG Specialists (QES) to provide the final patient report.

This study was undertaken in the UK within the UK healthcare system; therefore, results may vary.

Zio™ XT is only available within the UK.

Zio™ XT and ZEUS are UKCA-marked (UKCA0086).
