Abstract

In medical research, particularly in the field of rheumatology, there is great interest about the concept of responsiveness of outcome measures as a sign of changes in the patient's health status. However, the terminology surrounding this concept and the methods of analysis are confusing and lacking in consensus.

We present a review about the concept and analysis of responsiveness taking into account both, the characteristics of the responsiveness and the type of design and predictable change in the sample being studied.

Key words:
Responsiveness
Outcome measures
Responsiveness statistics
Resumen

En la investigación médica, y en especial en el ámbito de la reumatología, hay gran interés sobre el concepto de sensibilidad al cambio de un instrumento de medida como posible reflejo de modificaciones en la situación clínica del paciente. Sin embargo, la terminología de este concepto y su metodología de análisis están rodeadas de confusión y falta de consenso.

Se presenta un trabajo de revisión sobre el concepto y el análisis de la sensibilidad al cambio teniendo en cuenta tanto las características de la sensibilidad como el tipo de diseño y cambio previsible en la muestra en estudio.

Palabras clave:
Sensibilidad al cambio
Medidas de desenlace
Estadísticos de sensibilidad al cambio
