Age and clinical factors associated with functional outcome at six months in patients with ischemic stroke treated in 2011 at the Neurological Institute of Colombia

Introduction: functional outcome in patients who have suffered an ischemic stroke (IS) may be determined by factors such as age, gender, cardiovascular risk factors, comorbidities and etiology of the disease, they can define the severity or prognosis.Objective:To assess the association between demographic, etiologic and clinical and functional outcome (favorable or unfavorable) to six months follow-up in patients with IS.Materials and methods:Retrospective study of case-control adult stroke patients, a model of logistic regression was performed to identify predictors of an unfavorable functional outcome (mRS 3-6) at six months follow up. The entry of the variables was performed by the method steps forward (likelihood ratio) and evaluated the data fit the model using the Hosmer-Lemeshow. Adjusted ORs were estimated with the model coefficients and their confidence intervals and p value.Results: 275 ischemic stroke patients who had follow-up to six months were included in the analysis, 56.4% of patients were male and 85.5% were 51 years and older. In multivariate analysis, a higher probability of unfavorable functional outcome was observed to have an NIHSS score at admission ? 7 (OR 8.96, 95% CI 5.02-15.99), having 51 years or more (OR 5.0, 95% CI 1.86 -13.40) and hemorrhagic transformation (OR 6.61, 95% CI 1.6-26.87).Conclusion:ischemic stroke patients after six months follow-up with a NIHSS score at admission ? 7 with 51 years or more and who have suffered during the hospital stay hemorrhagic transformation have a worse functional outcome.
