Smartphone teleradiology application is successfully incorporated into a telestroke network environment.

BACKGROUND AND PURPOSE ResolutionMD mobile application runs on a Smartphone and affords vascular neurologists access to radiological images of patients with stroke from remote sites in the context of a telemedicine evaluation Although reliability studies using this technology have been conducted in a controlled environment this study is the first to incorporate it into a real world hub and spoke telestroke network The study objective was to assess the level of agreement of brain CT scan interpretation in a telestroke network between hub vascular neurologists using ResolutionMD spoke radiologists using a Picture Archiving and Communications System and independent adjudicators METHODS Fifty three patients with stroke at the spoke hospital consented to receive a telemedicine consultation and participate in a registry Each CT was evaluated by a hub vascular neurologist a spoke radiologist and by blinded telestroke adjudicators and agreement over clinically important radiological features was calculated RESULTS Agreement and 95 CI between hub vascular neurologists using ResolutionMD and 1 the spoke radiologist and 2 independent adjudicators respectively were identification of intracranial hemorrhage 1 0 0 92 1 0 1 0 0 93 1 0 neoplasm 1 0 0 92 1 0 1 0 0 93 1 0 any radiological contraindication to thrombolysis 1 0 0 92 1 0 0 85 0 65 1 0 early ischemic changes 0 62 0 28 0 96 0 58 0 30 0 86 and hyperdense artery sign 0 40 0 01 0 80 0 44 0 06 0 81 CONCLUSIONS CT head interpretations of telestroke network patients by vascular neurologists using ResolutionMD on Smartphones were in excellent agreement with interpretations by spoke radiologists using a Picture Archiving and Communications System and those of independent telestroke adjudicators using a desktop viewer CLINICAL TRIAL REGISTRATION INFORMATION www clinicaltrials gov unique identifier NCT00829361
