BEMBIBRE TABOADA, Rubén M. et al. Creación y validación de un instrumento para el seguimiento de pacientes con enfermedad cerebrovascular. Rev cubana med [online]. 2003, vol.42, n.1, pp.34-45. ISSN 0034-7523.

A study was conducted to create and validate an instrument for the follow-up of patients with stroke. The necessary variables to evaluate these patients were determined and procedures were established to obtain a score and a stratification by groups that allow a prognostic and evolutive classification of the new cases. A multicenter sample of 1 218 patients was analyzed by statistical methods, such as: Cramer’s V, automatic interaction detector, Chi square, logistic regression, Spearman’s method, optimum scaling, factorial analysis, and others, on EXCEL database transferred to SPSS. A manual instrument and 2 computer-generated tools: a clinical and a general one with correct percentages of classification over 90 and validated according to global result with 90.09; 92.98 and 94.14 %, respectively, were attained. The scores and the classification were made on the basis of the coefficients observed in an interval from 0 to 1. 3 risk groups were obtained: low (live without disability: 0£score £ 0.33), mean (live with disability: 0.33< score<0.67) and high (dead: 0.67 £ score £ 1). Some patients were directly classified by interactions. An instrument of scientific quantitative and qualitative rigor, unique in the country and easy to apply was obtained to give attention to patients suffering from stroke and, on that basis, to make decisions aimed at performing a medical practice of higher quality.
