ABSTRACT

BACKGROUND: Data suggest that elderly patients have less favorable outcomes after ischemic stroke. OBJECTIVE: To study the outcomes after intravenous tissue plasminogen activator (tPA) administration in elderly patients with acute ischemic stroke. METHODS: Cross-sectional study using prospective collected patient data maintained via our "tele-stroke" network, which provides acute care in 29 community hospitals within our region from 2013-2015. Exposure of interest was age divided into >80 years (octogenarian) or younger. Outcomes of interest were rate of intravenous tPA administration, hemorrhagic transformation (ICH), in-hospital neurological deterioration, and poor outcome defined as a composite of hospital discharge to long-term care facility or death. RESULTS: Mean age 67 ± 16 years, 57 % (743/1317) were women, and median (Md) NIHSS was 4 (Interquartile Range [IQR] 8). The rate of tPA was 20 % (267/1317). Compared to reported rates of tPA administration in the nation, our tPA rate exceeded the one from the literature (20 % v 3%, z = 2.83, SE = 0.04, p = .005). There were no differences in ICH or neurological deterioration. The octogenarian group had a higher proportion of poor-outcome (61 % vs. 23 %, p < 0.001) than the younger group but similar in-hospital case-fatality (25 % v 14 %, p = 0.09). Predictors of poor-outcome were age >80 (OR 4.9; CI, 2.0-12, p < .001) and α-NIHSS>9. (OR 8.7; CI, 3.5-20, p < .001). CONCLUSION: Our data suggest that in our "tele-stroke" network, rates of tPA administration are higher than those reported in the literature and that this rate was not different in octogenarians compared to younger patients. Octogenarians were not at risk for ICH or neurological deterioration after tPA administration. However, octogenarians had a higher risk of poor outcome.
