The Gambian National impregnated Bed Net programme : evaluation of effectiveness by means of case-control studies.
Two case-control studies, one on mortality and the other on malaria morbidity, were carried out in order to evaluate the impact of the Gambian National Insecticide Bed Net Programme during the second year of intervention and to explore the feasibility of such a study for the evaluation of programme effectiveness.
For the mortality study, children 1-9 years old who died during the 1993 rainy season were matched by age and sex with 2 healthy controls from the same village.
For the morbidity study, children 1-9 years old attending Fatoto or Jahalia Health Centres in The Gambia and who had fever and parasitaemia>5000/pL were matched by age with a child attending the health centres without fever or parasitaemia.
An additional healthy control was recruited from the case's village.
No impact of insecticide-treated bed nets on mortality was detected and this was in keeping with the results obtained by prospective surveillance.
A protective effect of insecticide-treated nets on malaria morbidity was detected when cases were compared with controls recruited at the health centres.
However, this disappeared when cases were compared with controls recruited from the cases'villages.
The mortality case-control study suggested that reducing the time between onset of disease and treatment may have an important impact on childhood mortality. (...)
