FACTOR INFLUENCING SPUTUM SMEAR CONVERSION AT THE END OF TWO MONTHS OF TUBERCULOSIS TREATMENT AMONG NEW SMEAR POSITIVE PULMONARY TUBERCULOSIS PATIENTS IN ADDIS ABABA, ETHIOPIA
International Conference on Environmental Health & Safety
Limited data are available on factors associated with persistent sputum smear positivity at the end of second months of anti-TB
treatment in Ethiopia. The present investigation was undertaken to identify factors influencing sputum smear conversion at
the end of second months of anti-TB among new smear positive pulmonary tuberculosis patients registered in a directly observed
treatment � short course (DOTS) programme in Addis Ababa, Ethiopia. Case-control study was performed in Addis Ababa public
health centers from December 6/2012-January 30/2013.Cases were 78 sputum smear positive TB patients who started anti-TB from
the period of February 9 to October 10/2012, with a positive sputum smear at the end of second months of anti-TB, randomly selected
from the prepared sampling frame. Two controls were recruited for each case from the same health facility and nearest the date of
diagnosis in each case with negative sputum smear at the end of second months of anti- TB treatment. Data were collected using a
pre-tested questionnaire by trained data collectors. Data was entered using EPI-Info version 3.5.1 and analyzed using SPSS version
20. Odds Ratio & 95% Confidence Interval (CI) used to measure the associations.
