Development of a simple diagnostic tool predicting the aseptic nature of a joint effusion: a pragmatic pilot study

This study made it possible to develop a simple and easily accessible predictive model in a primary care setting. This tool could make it possible to exclude <i>a priori</i> the septic aetiology of one out of four native joint effusions. Its performances remain to be determined on an independent population in a subsequent study (confirmation cohort in progress).
