Factibilidad, fiabilidad y validez del cuestionario VIG-express como instrumento de valoración multidimensional/geriátrica rápida: estudio multicéntrico

Abstract

Objective

To evaluate the feasibility, reliability and validity of the VIG-express questionnaire.

Design

Descriptive, observational, cross-sectional and multicenter study.

Setting

Catalonia.

Participants

24 professionals from 18 centers: 10 from Primary Care, 5 from hospitals acute, 2 intermediate care and 3 residential.

Main measurements

For the feasibility analysis, the administration time -mean and standard deviation (SD)-. The questionnaire was administered twice to the same patient by the same professional (intraobserver agreement), or by two different professionals (interobserver agreement), evaluating the intraclass correlation coefficient (ICC). Discriminant validity was calculated by comparing the responses of subgroup with higher fragility (percentile > 75) and subgroup with lower fragility (percentile < 25), for each item of the questionnaire.

Results

195 questionnaires were administered, 59 repeatedly, in a group of elderly (mean age of 79 years) and fragile (mean score of 0.33 in the Fragile Index-VIG). The average administration time was 6.52 minutes (DE: 6.02). The concordance in the degree of fragility score obtained a ICC of 0.95 (intraobserver) and 0.72 (interobserver). In discriminant validity, the differences in response frequencies between the two subgroups ranged from 1.7 (oncological disease) to 67.1 (medication management), all of which were statistically significant (p < 0.05), with the sole exceptions of the presence of oncological and neurological diseases.

Conclusions

The VIG-express questionnaire appears to be a feasible, reliable and valid tool for rapid multidimensional/geriatric assessment.
