IMPORTANCIA DE LA REFERENCIA MÉDICA EN EL DIAGNÓSTICO DE PARASITOSIS INTESTINALES POR MÉTODOS COPROPARASITOLÓGICOS

Abstract

Soil transmitted helminthes laboratory of the Tropical Medicine Institute studies feces by simple method, Formol-Triton-Eter and Baermann. Other coproparasitologic techniques like: Graham, Kinyoun and Kato-Katz are process if they are asked by physicians. The objectives of the current study were: evaluate the reference quality of the medical record, the impact in the final diagnosis applying coproparasitologic techniques and the occurrence of parasitic intestinal disease. Each reference was evaluated between 0 and 12 points, depending on the presence of quality parameters. For a total of 392 reference: 170 patients from public hospital, 157 from Tropical Medicine Institute, 38 from private hospital and 27 without information, the mean reference evaluation was 4 points. The poor quality of the reference did not permit to measure the impact in the final parasitologic diagnosis. The most frequent parasites were Blastocystis hominis (8,9 %), Entamoeba coli (3,5 %), Ascaris lumbricoides and Giardia intestinalis (both with 2,54 %). For the total HIV positive (10/173), only for 5, Kinyoun technique was solicited by the reference, Cryptosporidium sp. was positive for one. Two patients were referred because of pruritus ani and indication of Graham, both were negative for Enterobius vermicularis. Four patients referred with suspect of schistosomiasis without a Kato-Katz indication by the doctor. A complete reference of the medical record contributes to the application of the first choice of coproparasitologic techniques, to favor real diagnosis towards the benefit of the patients. We structured a new model of reference of the medical record to initiate an education labor of the health personal about the coproparasitologic techniques.
