Diagnostic workup for fever of unknown origin: a multicenter collaborative retrospective study.

ABSTRACT:

Objective

Fever of unknown origin (FUO) can be caused by many diseases, and varies depending on region and time period. Research on FUO in Japan has been limited to single medical institution or region, and no nationwide study has been conducted. We identified diseases that should be considered and useful diagnostic testing in patients with FUO.

Design

A nationwide retrospective study.

Setting

17 hospitals affiliated with the Japanese Society of Hospital General Medicine.

Participants

This study included patients ≥18 years diagnosed with 'classical fever of unknown origin' (axillary temperature ≥38°C at least twice over a ≥3-week period without elucidation of a cause at three outpatient visits or during 3 days of hospitalisation) between January and December 20
