Objective:
To determine the validity of an antimalarial drug history.
Design:
During a chloroquine sensitivity study carried out from 27 February to 13 April, 1995, an antimalarial drug history was obtained from the patients. A urine test was used as a gold standard to screen for antimalarial drugs in these patients.
Setting:
Two Mutare district primary health care centres.
Subjects:
Fifty clinical malaria cases were screened.
Main Outcome Measures:
Cases were classified in a two by two contingency table based on the reported antimalarial drug and the results of the urine test. Positive predictive value and negative predictive value were then examined.
