To explore the burden of drug-resistant tuberculosis in Khyber Pakhtunkhwa, Pakistan. The cross-sectional study was conducted from March 1, 2016, to February 28, 2017, at the Khyber Pakhtunkhwa Tuberculosis Reference Laboratory, Hayatabad Medical Complex, Peshawar, Pakistan, and comprised referred suspected tuberculosis patient samples. Drug Susceptibility testing on all Mycobacterium tuberculosis complex strains was performed and data was subjected to statistical analysis.

Of the total, 1351 (16.5%) samples were positive on culture. Drug susceptibility testing showed 525 (39%) samples to be resistant to at least one of the first- and second-line drugs. Among the culture-positive cases, 5 (0.4%) were extensively drug-resistant, 62 (4.6%) multi-drug resistant, 243 (18%) polyresistant, 215 (16%) monoresistant and 826 (61%) were pan-sensitive.
