Therefore, this study identify the outcome of tuberculosis treatment at Tembagapura Hospital and Kuala Kencana Clinic PT. Freeport Indonesia (PTFI) in Mimika District, Papua. Methods: A retrospective cohort study was conducted on 199 tuberculosis (TB) patients who were treated and registered in Tembagapura hospital and Kuala Kencana Clinic PTFI in Mimika District, Papua. Patients were categorised as having successful or unsuccessful treatment outcome. Data were entered into Stata/MP 13.1 for analysis from January, 2016 to Desember, 2018. The survival probability was analyzed by the Kaplan Meier method and Cox regression analysis was applied to factors associated during TB treatment outcome. Results: The survival probability in the sixth month was 82.85% while the cumulative survival probability at the end of the treatment period was 77.33%. A majority of unsuccessful treatment (12.8%) occurred during the intensive phase of the treatment. There was no significant in the survival curves of sex, etnic, age group, TB type, patient type, smoking habits, location of occupational, occupational type, level of occupational, DM status (ρ-value log rank >0.05). HIV history (ρ=0.003) and patient referral form other facilities (ρ=0.02) were significantly difference in the survival curve. Cox regression showed that patient who had HIV history (HR 2.96; 95% CI 1.44-6.11) and referral other health facilities (HR 2.65;95% CI 1.22-5.73) were associated with unsuccessful treatment outcomes. Conclusions: HIV infection and referral other health facilities are both factors associated unsuccessful treatment. Interventions should focus on patients during the intensive phase, need to improve TB treatment especially to those who have referral from other health facilities and coordination of integrated TB and HIV services Tembapura hospital and Kuala Kencana Clinic PTFI with DHO and other health facilities.
