Trends in fever case management for febrile inpatients in a low malaria incidence setting of Tanzania.

Abstract

Objectives

In 2010, WHO published guidelines emphasising parasitological confirmation of malaria before treatment. We present data on changes in fever case management in a low malaria transmission setting of northern Tanzania after 2010.

Methods

We compared diagnoses, treatments and outcomes from two hospital-based prospective cohort studies, Cohort 1 (2011-2014) and Cohort 2 (2016-2019), that enrolled febrile children and adults. All participants underwent quality-assured malaria blood smear-microscopy. Participants who were malaria smear-microscopy negative but received a diagnosis of malaria or received an antimalarial were categorised as malaria over-diagnosis and over-treatment, respectively.

Results

We analysed data from 2098 participants. The median (IQR) age was 27 (3-43) years and 1047 (50.0%) were female. Malaria was detected in 23 (2.3%) participants in Cohort 1 and 42 (3.8%) in Cohort 2 (p = 0.059). Malaria over-diagnosis occurred in 334 (35.0%) participants in Cohort 1 and 190 (17.7%) in Cohort 2 (p < 0.001). Malaria over-treatment occurred in 528 (55.1%) participants in Cohort 1 and 196 (18.3%) in Cohort 2 (p < 0.001). There were 30 (3.1%) deaths in Cohort 1 and 60 (5.4%) in Cohort 2 (p = 0.007). All deaths occurred among smear-negative participants.

Conclusion

We observed a substantial decline in malaria over-diagnosis and over-treatment among febrile inpatients in northern Tanzania between two time periods after 2010. Despite changes, some smear-negative participants were still diagnosed and treated for malaria. Our results highlight the need for continued monitoring of fever case management across different malaria epidemiological settings in sub-Saharan Africa.

Adjunct Professor in the Department of Medicine

I am an Adjunct Professor of Medicine, Pathology, and Global Health. My work with Duke University is primarily based in northern Tanzania where I am former Site Leader and current Principal Investigator on projects linked to Duke University’s collaborative research program at Kilimanjaro Christian Medical Centre. I oversee the design and implementation of research studies on infectious diseases, particularly febrile illness, invasive bacterial disease, zoonotic infections, and infectious diseases diagnostics. In addition, I am Professor of Medicine, Pathology, and Global Health at the University of Otago and a medical epidemiologist with the US Centers for Disease Control and Prevention (CDC). My CDC work focuses on non-malaria febrile illness.
