Causes of unexplained fevers in Nepal (DEFINe)
Determination of Etiology of Febrile Illness in Nepal (DEFINe Study)
This project will test whether adding cultures and ELISA blood tests can find the causes of fever and reduce unnecessary antibiotic use in adults admitted with 3–21 day unexplained fevers in Nepal.

What this trial studies
This hospital-based interventional effort enrolls adults with documented fevers of 3 to 21 days and no clear clinical, radiological, or routine laboratory diagnosis. Participants receive additional microbiological testing beyond local standard of care, including culture techniques and ELISA serology for seven pathogens not routinely tested in Nepal. The study compares etiologic detection and subsequent antimicrobial use when these additional tests are applied. Results will inform whether broader diagnostic testing changes treatment decisions and identifies otherwise-missed causes of febrile illness.
Who should consider this trial
Good fit: Adults aged 16 years or older admitted to the medical unit at Patan Academy with documented fever lasting 3–21 days, no obvious diagnosis after initial testing, and who can provide informed consent.
Not a fit: Outpatients, children under 16, immunocompromised individuals (including known HIV or ANC <500), patients with fevers shorter than 3 days or longer than 21 days, those being discharged from the emergency room, or recently hospitalized patients are not expected to benefit from this protocol.
Why it matters
Potential benefit: If successful, this could let clinicians target treatment more accurately, reduce unnecessary antibiotic use and costs, and help slow antibiotic resistance.
How similar studies have performed: Previous regional studies have shown that adding microbiological testing can identify more causes of fever and reduce empirical antibiotic use, though this specific panel of tests has not been widely implemented in Nepal.
