Factors Related to Successful Treatment of Drug-Resistance Tuberculosis in H. Adam Malik Hospital, Medan, Indonesia

The number of drug-resistant TB cases keeps increasing for over the years. Drug-resistant TB is adifficult case because of the treatment, many side effects, more expensive, and less satisfactory results. This study is a retrospective cohort design aimed to determine the factors influencing the success of TB drug resistance treatment at H. Adam Malik Hospital during 2012–2015. The number of confirmed patients with drug-resistant TB was 223 people, 153 male, and 70 female. Two factors have been found to affect the treatment outcomes significantly, age and resistance pattern (P<0.05). Patients aged <50 years old have 2.73 times greater chance of recovery than patients aged ≥50 years old. Based on resistance pattern, patients with rifampicin resistant or poly-resistant would be 6.4 times more likely to recover compared with pre-XDR patients. There was no significant difference in the success rate of treatment among MDR patients compared with rifampicin resistant or poly-resistant cases. Age and resistance pattern has been proved to influence the success of drug-resistant TB treatment.
