An Audit of Sputum Smear Negative Pulmonary Tuberculosis Cases in Kinta District Perak in 2011

摘要

58 cases of sputum smear negative pulmonary tuberculosis (PTB) were reported to Kinta Health Department between January and June 2011. It was found that 47 cases (81%) were sputum smear negative cases. Six cases (10.3%) were actually sputum smear positive but were wrongly reported as smear negative. Five cases (8.6%) were misdiagnosed as tuberculosis. Majority of these patients (82.7%) sought consultation and treatment after two weeks of having cough. Only 6.9% sought treatment for cough that was less than two weeks old. Accurate diagnosis of PTB is crucial and the Perak State Health Department needs to quickly adopt steps to improve the situation.
