Analysis on the effect of external quality assessment of the pulmonary tuberculosis sputum examination in Sanmenxia from 2004 to 2007

Abstract

Abstract: Objective To discuss the function of external quality assessment (EQA) in the sputum examination. Methods4133 sputum smears selected for EQA from 2004 to 2007 were analyzed. ResultsThrough carrying out EQA, the qualification rate of sputum slides increased from 71.2% in 2004 to 90.7% in 2007,the positive coincidence rate rose from 95.9% in 2004 to 98.7% in 2007, and the negative coincidence rate rose from 97.8% in 2004 to 99.5% in 2007. ConclusionsEQA is an essential guarantee for improving the quality of the sputum smear examination.

Key words: pulmonary tuberculosis/diagnosis, sputum, quality control
