| Popis: | Background Atrial fibrillation (AF) is a known risk factor for embolic stroke. Establishing a diagnosis of AF will guide clinical decision making and help with downstream secondary stroke prevention. Patch technology is increasingly used for long-term cardiac monitoring for arrhythmia detection, as healthcare organisations look for new innovative ways to streamline service delivery. We were selected as a host site to evaluate the service and patient benefits of Zio XT in AF detection for cryptogenic stroke, as part a Artificial Intelligence Award. Purpose To evaluate the service and patient benefits of patch technology versus traditional Holter in a Stroke / TIA pathway. Methods The Zio XT data were collected between March and December 2021. A total of 778 patients were included. We only selected patients who were referred for a long-term ambulatory monitoring following a recent diagnosis of stroke or transient ischaemic attack (TIA) of an unknown cause (cryptogenic). The stroke pathway operates across three sites and all were included. We undertook a retrospective analysis of our previous pathway using Holter monitoring and sampled 100 stroke / TIA patients who underwent 24–72 hours of monitoring between January to June 2019. In order to obtain the requisite data a variety of sources were scrutinised: referral letters, test reports, patient medical records, internal clinical systems and third-provider platforms. Results The comparison of the ECG technologies showed the Zio XT used less staff time. We found a 50% reduction in-clinic monitor fitting when compared with Holter. Zio XT were all analysed by the provider staff resulting in significant savings in service resource time for analysis. The Zio XT had a faster test turnaround time (referral to report available), 19 days (inclusive of 14 days wear time) for Zio compared with 60 days for Holters. The rapid Zio turnaround led to a 27.5% reduction in repeat clinic appointments, due to results being unavailable for the consultation (table 1). Zio XT also had fewer repeat testing due to inconclusive results, 1% for Zio versus 16% for Holter. AF yield did not vary significantly between technologies, 3% yield for both Holter and Zio, which could be due to the young mean age of the stroke/ TIA the patient cohort: 63.8 years for Holter versus 62.9 years for Zio XT. Conclusion Introducing new ECG technologies such as Zio XT could increase outpatient and diagnostic capacity due to patches being more readily available than Holters, reduced reliance on clinical staff for fitting and analysis as well as fewer repeat clinic appointments. Overall, access to rapid long term cardiac monitoring has benefits over traditional Holter monitoring for TIA/stroke patients and service delivery.
