Abstract
Background and Purpose:
Intravenous recombinant tissue plasminogen activator (IV rt-PA) is an effective treatment of acute ischemic stroke. The safety and efficacy of IV rt-PA were extensively studied in adults, including both octogenarians and nonagenarians.This study provides safety outcome of exclusive nursing home (NH) residents (dependent on activities of daily living [ADLs]) , who received IV rt-PA. Not much literature or studies are available exclusively on the NH residents.
Aim:
To assess the safety and outcome of IV rt-PA in patients from NHs who were admitted to our university-based tertiary care hospital, using data from a prospective stroke registry.
Methods:
Our study is a retrospective review of patients living in nursing facilities, admitted to our neuroscience intensive care unit after receiving IV rt-PA, from January 2010 to June 2018. We reviewed the clinical symptoms, comorbid conditions, medications, diagnostic evaluation, complications, and functional outcomes. The functional outcome was assessed based on the modified Rankin Scale (mRS) at the time of discharge, and 1- and 3-month follow-up.
Results:
Twenty-eight NH residents (20 [71.4%] were female with a mean age of 80.96 +/− 12.43 years) were identified who had received IV rt-PA for symptoms of acute ischemic stroke. The median mRS on admission was 3, and all of them were dependent on ADL. Twenty-seven (96.5%) patients were treated within the window (≤3 h) for IV rt-PA. There were no IV rt-PA-related violations from both our hospital and outside hospital treatment protocols. The initial computed tomographic (CT) scan of 8 (28.5%) patients revealed evidence of infarction. CT angiogram of head and neck revealed an acute intracranial blood vessel occlusion in 13 (46.4%) patients, and asymptomatic stenosis of intracranial and extracranial blood vessels in 4 (14.2%) patients. Mechanical thrombectomy was attempted in 6 (21.4%) patients and among them, the procedure was unsuccessful in 2 (7.1%) patients due to severe stenosis. One (1/21; 16.6%) patient received an intra-arterial rt-PA, and 5 (5/6;83.3%) patients developed symptomatic intracranial hemorrhage within 24 h following the procedure. Families of 9/28 (32.1%) patients decided to withdraw care. The median mRS on 30 and 90 days follow-up was 4 (interquartile range: 3-6).
Conclusion:
In this population, mechanical thrombectomy has a high risk for hemorrhagic conversion. IV rt-PA treatment in the NH residents may not improve the outcome of ischemic stroke.
