Abstract

Objectives: The diagnosis of pulmonary tuberculosis (PTB) requires identification of M. tuberculosis in sputum culture. However, this method has many limitations and diagnosis of PTB has to rely on sputum smear of acid-fast bacillus (AFB). Record from the Ministry of Health showed that only 55.2% of pulmonary tuberculosis had positive sputum smear. This study aimed to identify the epidemiological characteristics of PTB patients notified in Tanah Merah district.

Methods: We reviewed 130 cases of PTB extracted from Tuberculosis Information System (TBIS) database at Tanah Merah District Office from January 2010 until June 2011.

Results: The mean age (SD) of pulmonary tuberculosis patients was 48.5 (16.3) years. There was male predominance with male:female ratio 3:1. A total of 94.6% of patients came from rural area while only 5.4% of patients came from urban area and 70% of PTB patients had positive sputum AFB. All patients with positive sputum AFB have chest radiograph lesion. As for patients that have negative sputum AFB, 92% of them have chest radiograph lesion while 3% of them have no chest radiograph lesion. There was a significant association between sputum AFB and chest x-ray finding.

Conclusion: The percentage of sputum AFB positive in Tanah Merah district was higher than the national percentage. Chest x-ray was associated with sputum AFB.
