| Abstract |
Predictors of short-term readmission after ischemic stroke have been previously identified, but few studies analyzed predictors of long-term readmission, namely early imaging findings and treatment with intravenous thrombolysis (IVT). To characterize predictors of hospital readmission during the first year after hospitalization for ischemic stroke. The study consists of a retrospective cohort of consecutive ischemic stroke patients admitted in a Portuguese university hospital during 2013, who survived index hospitalization. We collected clinical and imaging information using the electronical clinical record. Information concerning 1-year unplanned hospital readmissions was assessed using the Portuguese electronic Health Data Platform. Descriptive and univariate analyses, Kaplan-Meier survival curve and multivariate survival analysis with Cox regression model were used. We included 480 patients, 50.6 % women, median age 79 years (interquartile range = 68-85). One-year hospital readmissions occurred in 165 patients [34.4 %, 95 % confidence interval (95 % CI) 30.2-38.7]. The main causes for readmission were infectious diseases (43.8 %), ischemic stroke or transient ischemic attack recurrence (13.2 %) and cardiac diseases (6.4 %). In-hospital mortality associated with readmission was 23.0 %. The independent predictors of 1-year hospital readmission after ischemic stroke were admission mini-National Institute of Health Stoke Scale [hazards ratio (HR) 1.05, 95 % CI 1.02-1.08, p = 0.002], and mild or absent early signs of ischemia on admission computed tomography (CT) (HR 0.54, 95 % CI 0.32-0.91, p = 0.021) and IVT (HR 0.11, 95 % CI 0.01-0.80, p = 0.029). Hospital readmission during the first year after ischemic stroke occurs in 1/3 of patients and is associated with high in-hospital mortality. Clinical stroke severity, early signs of ischemia on admission CT, and treatment with IVT are independent predictors of 1-year hospital readmission. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 August 2016.
All research outputs
#21,623,829
of 24,135,931 outputs
Outputs from Internal and Emergency Medicine
#863
of 1,025 outputs
Outputs of similar age
#331,593
of 373,774 outputs
Outputs of similar age from Internal and Emergency Medicine
#18
of 25 outputs
Altmetric has tracked 24,135,931 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,025 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.8. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 373,774 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 25 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
