Using telemedicine to facilitate thrombolytic therapy for patients with acute stroke.

ABSTRACT

BACKGROUND: Recent stroke-care requirements state that all stroke patients should be screened for intravenous recombinant tissue plasminogen activator (rt-PA) and treated, if the appropriate inclusion and exclusion criteria are met. Two community hospitals 90-130 miles east of Houston deployed telemedicine (videoteleconferencing) to provide acute stroke consultative services. DEVELOPING A TELEMEDICINE CAPACITY According to the Brain Attack Coalition's recommendations, neurosurgical services need to be accessible within two hours. Given their incomplete neurology coverage, the remote-site hospitals identified telemedicine as the best option, with the University of Texas Health Science Center at Houston stroke team as the provider of expertise. RESULTS: In the 13 months preceding the telemedicine project (January 2003-March 2004), 2 (.8%) of 327 patients received rt-PA, compared with 14 (4.3%) of 328 patients during the telemedicine project (April 2004-May 2005), p < .001). Seven patients had > or = 4 points improvement in a stroke scale at 24 hours posttreatment. Three patients worsened during the 24-hour assessment. No intracerebral hemorrhages occurred. Door-to-needle median time was 85 minutes (range, 27-165 minutes). DISCUSSION: Telemedicine facilitated thrombolytic therapy for acute stroke patients and is intended not to replace care provided by remote-site providers but rather to address a time- and spatially related emergency need.
