Abstract
Background and Purpose-Basilar artery occlusion (BAO) is a stroke subtype with poor prognosis, but recanalizing therapies have been reported to be effective. We investigated whether initial admission to telemedically linked general hospitals with subsequent stroke-center transfer is related to poorer outcome than direct admission to stroke centers. Methods-All BAO cases of 3 stroke centers in Munich and 1 center in Regensburg between March 1, 2003 and December 31, 2004 were included, either if patients were directly admitted to stroke centers (n = 23) or had initial admission to general hospitals of the telemedical network for integrative stroke care (TEMPiS) and secondary transfer to stroke centers ( n = 16). BAO was defined as angiographically (CTA, MRI or conventional angiography) confirmed occlusion of the basilar artery. Baseline parameters and therapeutic procedures were recorded. One-year follow-up was conducted prospectively. Results-Differences in baseline parameters were not statistically significant. Time from onset to first angiography was significantly longer in patients with secondary transfer (mean: 355 +/- 93 minutes versus 222 +/- 198 minutes; P < 0.01), mainly attributable to transfer duration (mean: 156 +/- 73 minutes). In-hospital mortality (22% versus 75%; P < 0.01) and 1-year-mortality (30% versus 81%; P < 0.01) were lower for patients with direct admission to stroke centers. Fifty-two percent of directly admitted patients versus 13% of patients with secondary transfer (P = 0.02) were living at home after 1 year. Conclusions-BAO patients who were admitted primarily to community hospitals had a worse prognosis. Patients with typical symptoms should have direct access to stroke centers, or may need bridging therapies.
