Trends in burden of multidrug-resistant tuberculosis in countries, regions, and worldwide from 1990 to 2017: results from the Global Burden of Disease Study

Abstract

Background This study aimed to estimate the trends of multidrug-resistant tuberculosis (MDR-TB), which can be used to inform health strategies.Methods Data were collected from the Global Burden of Disease Study 2017. The estimated annual percentage change (EAPCs) were calculated to assess the trends of MDR-TB burden from 1990 to 2017.Results Globally, the ASR of MDR-TB burden including incidence, prevalence, death and disability-adjusted life years (DALYs) had pronounced increasing trends from 1990 to 1999, with the EAPCs were 17.63(95% confidence interval [CI]: 10.77 to 24.92), 17.57(95%CI: 11.51 to 23.95), 21.21(95%CI:15.96 to 26.69), and 21.90(95%CI: 16.55 to 27.50), respectively. Particularly, the largest increasing trends were seen in areas and countries of low and low-middle sociodemographic index (SDI). However, the trends in incidence, prevalence, death and DALYs of MDR-TB decreased globally from 2000 to 2017, with the respective EAPCs were −1.37(95%CI: −1.62 to −1.12), −1.32(95%CI: −1.38 to −1.26), −3.30(95%CI: −3.56 to −3.04) and −3.32(95%CI: −3.59 to −3.06). Decreasing trends of MDR-TB were observed in most regions and countries, particularly that of death and DALYs in Slovenia were −18.96(95%CI: −20.82 to −17.06) and −19.35 (95%CI: −21.10 to −17.55), respectively. Whereas the pronounced increasing trends of MDR-TB occurred in Papua New Guinea, Singapore, and Australia.Conclusions the ASR of incidence, prevalence, death and DALYs of MDR-TB showed decreasing trends from 2000 to 2017. However, the MDR-TB burden remains a substantial challenge to the TB control globally, and requires effective control strategies and healthcare.
