Tuberculosis Case Finding in Kulon Progo District, Yogyakarta, Indonesia: Passive versus Active Case Finding Using Mobile Chest X-ray

Active-case finding (ACF) using chest X-ray is an essential method of finding and diagnosing Tuberculosis (TB) cases that may be missed in Indonesia’s routine TB case finding. This study compares active and passive TB case-finding strategies. A retrospective study of TB case notification was conducted. Data between 1 January and 31 December 2021, was used. The population in this study were TB cases notified from Kulon Progo District health facilities, including those found through routine activities or active-case findings. A total of 249 TB cases were diagnosed in Kulon Progo in 2021, and 102 (41) were bacteriologically confirmed. The TB patients’ ages ranged from 0 to 85 years (median 52, IQR 31–61). The majority of cases were male (59, 147/249) and mostly among people aged 15–59 (61.4, 153/249). The proportion of clinical TB diagnoses among cases found from active-case findings was 74.7 (68/91) while the proportion among passive-case findings was 50 (79/158). Active-case finding contributed 91 (36.5) TB cases to the total cases detected in Kulon Progo in 2021. The use of chest X-rays in active-case findings likely contributed to the detection of a higher proportion of clinical TB than in passive-case findings. © 2024 by the authors.
