ABSTRACT

Purpose

To evaluate the inter-rater reliability and predictive validity of the Frenchay Activities Index (FAI) in patients after stroke.

Methods

One hundred sixty-one patients were selected for consecutive application of the FAI and National Institutes of Health Stroke Scale (NIHSS). Spearman’s test was used for correlation between different scales. The FAI and NIHSS association was evaluated using ordinal logistic regression. Additionally, 36 patients underwent FAI rating on the same day by two independent evaluators.

Results

A negative correlation between the FAI and the NIHSS scores (p = 0.017 r = -0.22) was found. Adjusting all variables with possible association with the NIHSS, ordinal logistic regression showed that the FAI had a significant association with NIHSS scores (OR 0.93, 95% CI 0.87 to 0.99, p: 0.033). The inter-rater agreement was considered good, k = 0.66 (0.54 to 0.78), p < 0.001.

Conclusions

The FAI is a valid and useful method to assess instrumental activities before acute stroke in a Brazilian population.

RESUMO

Objetivo

Avaliar a confiabilidade inter-examinador e a validade preditiva do Índice de Atividades de Frenchay (FAI) em pacientes após acidente vascular cerebral.

Métodos

161 pacientes foram selecionados para aplicação consecutiva da FAI e NIH Stroke Scale (NIHSS). O teste de Spearman foi utilizado para correlação entre as diferentes escalas. A associação FAI e NIHSS foi avaliada por meio de regressão logística ordinal. Adicionalmente, 36 pacientes foram submetidos à aplicação do FAI por dois avaliadores independentes, no mesmo dia.

Resultados

Foi encontrada uma correlação negativa entre o FAI e o NIHSS (r = -0,22; p = 0,017). Ajustando todas as variáveis com possível associação com NIHSS, a regressão logística ordinal demonstrou que o FAI tem associação significativa com o NIHSS (OR 0,93, 95% CI 0,87-0,99, p: 0,033). A concordância entre avaliadores foi considerada boa, k = 0,66 (0,54-0,78), p < 0,001.

Conclusões

FAI é um método válido e útil para avaliar atividades instrumentais antes de AVC agudo em uma população brasileira.
