Abstract: Tuberculosis (TB) disease is one of the chronic diseases which could influence the patients’
quality and quantity of life. The quality and quantity of life may be affected by the disease itself or the
disease’s treatment due to the adverse effect. The purpose of this research is to predict Quality
Adjusted Life Years (QALYs) value before and during the treatment using Indonesian version of St
George Respiratory Questionnaire (SGRQ) instruments which has been validated. This study used a
cross sectional design conducted prospectively in 91 new patients diagnosed as pulmonary TB in
Pulmonary Clinics, province of Yogyakarta on November 2013 until April 2015. Patients filled out the
SGRQ and the total score was counted to predict the QALYs.We found that the predicted QALYs before
and during the treatment significantly different with value was 0,691 before the treatment and they
were 0.805; 0.846; 0.877; 0.892 and 0.899 during the first until fifth month of treatment respectively
(p<0,05). The TB treatment can improve health status from index number 0.691 to 0.899 which is 0.208
during the treatment will produce 2 QALYs. We conclude that the predicted QALYs of TB patients
during the treatment are good and show that the patients experience significant improvement of
quality of life.
