Analysis of Malaria Diagnostic Network, 2008

The national diagnosis of malaria network is founded in 1995. Since then, the group of parasitology, the National Diagnostic Network of the National Institute of Health has implemented the Malaria Program within the National Laboratory Network by developing various activities in order to strengthen the diagnosis and treatment of this disease in the country. The malaria diagnostic network exists in 989 municipalities and consists of 1,640 clinical laboratories and 1,308 microscopy posts, these data show an increase of 13.4% in the municipal network coverage, a decrease of 3.5% the number of clinical laboratories and an increase of 11.8% in microscopy posts with respect to the year 2007.

This study aimed to evaluate the network coverage and quality of the malaria diagnosis in 2008. These results do not cover the information from the departments of Magdalena and Casanare. 387,993 samples were diagnosed, out of which 61,304 were positive. For P. vivax 40,937; for P. falciparum 20,013; 353 for association and 1 for P. malariae. As for the direct external evaluation of the departmental performance was: agreement: 92.7%, coverage of 100% and 96.9% participation. 60.6% of laboratories obtained a concordance above 95%. The indirect external evaluation of performance was: concordance (+): 99.3% concordance (-): 100%, kappa 0.99, IKE: 0.95, Participation: 96.9%. To direct external evaluation of performance, at the municipal level, we obtained the following data: concordance = 84.9% coverage: 40.7%, and for the indirect external evaluation was: correlation (+): 95.3% and concordance (-): 98.1%, kappa: 0.94, IKE: 0.79, coverage: 89.2%.
