Analysis of mortality in the stroke code in Ourense province, Spain. An approximation in old age

Abstract

Purpose: The present study aims to analyze the relationship between the risk of mortality in stroke patients after 30 days, 6 months, and 1 year, and various factors such as: care time, bleeding complications of the event, awakening stroke and changes in the NIHSS scale. Adjusted in turn based on  age, sex, and reference hospital.

Method: A longitudinal, retrospective, and observational study applied to 153 patients with a mean age of 76±12 years, of which 83 are women who are included within the stroke code in the Province of Ourense, Galicia. The variables to be considered were the NIHSS scale, door-CT times and CT attention, type of stroke, hemorrhagic transformation and time of onset (upon awakening). The data were stratified by Age (older and younger than 80 years), Sex (Men and Women), and Hospital Center (Ourense, Verín, and O Barco).

Results: The results of the Pearson’s Chi-square hypothesis tests demonstrated that no statistically significant associations were found between mortality and the condition of awakening stroke , hemorrhage or NIHSS (p-value > 0.05) in any of the studied sexes nor in the ages considered.

Conclusions: The present study demonstrated that there is insufficient representative evidence between factors such as age, sex, hemorrhagic transformation, NIHSS value, awakening stroke, and mortality after 30 days, 6 months and 1 year. Neither was a conclusive result found between mortality and door-CT and attention-CT times.
