Cost implications of improving malaria diagnosis: findings from north-eastern Tanzania.
BACKGROUND: Over diagnosis of malaria contributes to improper treatment, wastage of drugs and resistance to the few available drugs. This paper attempts to estimate the rates of over diagnosis of malaria among children attending dispensaries in rural Tanzania and examines the potential cost implications of improving the quality of diagnosis. METHODOLOGY/PRINCIPAL FINDINGS: The magnitude of over diagnosis of malaria was estimated by comparing the proportion of outpatient attendees of all ages clinically diagnosed as malaria to the proportion of attendees having a positive malaria rapid diagnostic test over a two month period. Pattern of causes of illness observed in a or=5 year age group in the lower transmission site (RR 14.0 95%CI 8.2-24.2). In the low transmission site the proportion of morbidity attributable to malaria was substantially lower in
