Impact of Differential and Systematic Diagnosis of Dengue, Chikungunya and Malaria on Patient Management and Antibiotic Use in West Africa

Not Applicable

Completed

• Conditions: Dengue; Malaria; Chikungunya

• Registration Number: NCT06257810
• Lead Sponsor: BioMérieux

Brief Summary

The differential and systematic diagnosis of malaria, dengue and chikungunya in patients with fever (≥38.5°C) of undetermined etiology would allow the identification of infection by these pathogens and thus limit the inappropriate use of antibiotics (discontinuation or non-initiation) and optimize the clinical management and prognosis of patients.

Detailed Description

The research hypotheses are as follows:

* Systematic diagnosis of malaria, dengue and chikungunya using diagnostic tests would improve the clinical management of patients with fever of undetermined etiology and reduce the misuse of antibiotics (discontinuation or non-initiation) and associated resistance.

* Improved management is associated with a reduction in the use of hospital resources, professional inactivity and an improvement in the quality of life and satisfaction of patients.
