Evaluation is an essential management tool for the improvement of publ
ic health programmes or projects. As malaria morbidity and mortality c
ontinue to increase in most countries in Africa, international agencie
s and malaria control programme managers have identified the strengthe
ning of programme evaluation as an important strategy for improving th
e efficiency and effectiveness of malaria control programmes. Managers
can develop an evaluation strategy only after they have defined progr
amme objectives and planned specific programme activities. Indicators
should be directly related to programme objectives and should be selec
ted on the basis of the following criteria: their validity; reliabilit
y; ability to detect change within a reasonable time period and as a r
esult of successful programme implementation; ability to be interprete
d; and usefulness in guiding programme change. Only those indicators t
hat can be measured with available programme resources should be selec
ted. Managers will also need to identify the sources of indicator data
and to determine how often each indicator will be measured. Programme
managers should develop criteria or indicators for the following: pro
gramme policies and plans; the process of programme implementation; th
e outcomes of malaria control interventions in disease management and
prevention; and programme impact in terms of reductions in malaria-rel
ated mortality and morbidity. Key issues related to the management of
evaluation activities within a national programme include the need to
begin with available resources and build incrementally, to explore opt
ions for administering evaluation activities; to select, train and sup
ervise staff who carry out evaluation activities; to develop quality c
ontrol strategies; and to ensure that data are managed and communicate
d in ways that support effective programme decision-making. For evalua
tion to lead to improvements in malaria control programmes it must be
clearly defined as a part of the programme management process. Program
me managers should lead this developmental process, ensuring that eval
uation methods produce the information they need to monitor and improv
e their programmes at reasonable cost.
