Introduction: Rapid dissemination and coordination of clinical and imaging data among multidisciplinary team members is essential for optimal acute stroke care. Standard desktop EMRs are ill-suited for this purpose, but mobile smartphone and tablet applications are highly promising platforms for accelerated, data-driven patient diagnosis and treatment. This study tested an advanced mobile integrated system for distribution of patient clinical and imaging information.

Methods: We tested the iStroke/Synapse ERm system (Figure) for smartphone and tablet display and integration of clinical data, CT, MR, and catheter angiographic imaging, and real-time stroke team communications, in consecutive acute neurovascular patients at a Comprehensive Stroke Center.

Results: From 5/2014 to 10/2014, the Synapse ERm application was installed and used by 33 stroke team members, in 84 Code Stroke ED patients. Patient age was 69.1 (±17.5), with 40.5% female. Final diagnosis was: ischemic stroke 66%, TIA 7%, ICH 6%, and CV mimic 21%. Each patient record was viewed on average 13 times by at least 3 team members. The most used feature was CT, MR and cath angio image display, viewed on average 4 times per patient by at least 2 users. In-app tweet team communications were sent by average 2 users per case and viewed by average 6 team members. Use of the system was associated with treatment times that exceeded national guideline targets for thrombolysis and endovascular thrombectomy, including door-to-needle 50 min (IQR 24-60) and door-to-groin 92 min (IQR 65-128). In user surveys, the mobile information platform was judged easy to employ in 91% of uses and of added help in stroke management in a substantial majority of cases.

Conclusion: The Synapse ERm system, a smartphone/tablet platform for stroke team communication and distribution and integration of clinical and imaging data, showed high ease of use, substantial added management value, and association with rapid processes of care.
