Call for letters of intent: Implementation research on rapid di-
agnostic testing in home management of malaria
Full version available at:
The UNICEF/UNDP/World Bank/WHO Special Programme for Research
and Training in Tropical Diseases (TDR) invites letters of in-
tent on implementation research to establish the role of rapid
diagnostic testing (RDT) in the context of home management of
malaria (HMM) in sub-Saharan Africa.
The HMM strategy has been developed in order to increase access
to prompt and effective antimalarial treatment by children with
uncomplicated malaria living in highly endemic areas in Africa.
The strategy is based on the assumption that a high proportion
of fever episodes are due to malaria, and seeks to improve a
frequent occurrence: mothers treating their children at home for
fever episodes ("hot body"), which is in most cases done inade-
In recent years, growing resistance to conventional antimalarial
drugs (chloroquine, sulphadoxine/pyrimethamine) has obliged many
countries to change treatment policy and adopt more efficacious
medicines, such as artemisinin-based combination therapies
(ACTs) as first-line antimalarial therapy. Concerns have been
raised with regard to the use of ACTs for antimalarial treatment
at the community level as these medicines are new and expensive,
and evidence-based delivery models are lacking. One particular
concern relates to the fact that malaria is a difficult disease
to diagnose by clinical examination only. Clinical diagnosis of
malaria may overestimate the true incidence of the disease and
lead to an excessive use of ACTs. This, in turn, could lead to
unnecessary expenditure, and facilitate the appearance of para-
site resistance to the new medicines. Therefore, some experts
have called for a more cautious use of ACTs, which should be re-
stricted to patients with a confirmed diagnosis of infection
with malaria parasites.
The use of RDT in the HMM strategy provides an opportunity to
improve diagnosis and administer targeted treatment only to
parasitologically confirmed malaria cases. However, RDT use also
has operational and financial implications. If it were to be
used routinely in the context of HMM, the well established HMM
strategy would be changed and additional costs incurred, which
may not necessarily be compensated by less use of the drugs.
Furthermore, the potential benefit of introducing RDT in terms
of improvement of clinical outcome in children, both treated and
not treated with ACTs, has to be proven. It is thus necessary to
carry out implementation research to establish the role of RDT
within the context of HMM with ACTs, based on the feasibility,
acceptability, risk-benefit and cost-effectiveness of its use at
the community level.
Objectives of the research
General objective: To establish the role of RDT in the context
of the HMM strategy with ACTs in sub-Saharan Africa.
- To evaluate the impact of RDT-oriented administration of ACTs
for malaria on the clinical outcome of the disease (in terms of
proportion of cases with full clinical recovery and incidence of
complications) within the context of HMM.
- To establish the cost-effectiveness of RDT in the context of
the HMM strategy with ACTs.
- To perform a risk/benefit analysis of RDT in the context of
the HMM strategy with ACTs.
- To describe the operational feasibility, acceptability and
safety of RDT in the context of the HMM strategy with ACTs.
Terms of reference
The research objectives will be met through open, randomized
controlled studies (to be developed at a later stage), imple-
mented in close collaboration with the national malaria control

vide information on the following:
