Setting: Manicaland Province, Zimbabwe. Objectives: To compare the utilisation and results of deploying Xpert® MTB/RIF in 13 (one provincial, six district and six rural) hospitals between January and June 2016, when Xpert was recommended only for those with presumptive multidrug-resistant tuberculosis (MDR-TB) and coinfection with human immunodeficiency virus (HIV), and between January and June 2017, when Xpert was recommended for all presumptive TB patients. Design: This was a cross-sectional study. Results: Xpert assays averaged 759 monthly in 2016 and 1430 monthly in 2017 (88% increase). Utilisation of Xpert averaged 22% monthly in 2016 and 42% in 2017 (88% increase). In 2017, utilisation of Xpert was significantly higher in provincial (82%) than in district (51%) and rural (26%) hospitals (P < 0.001). The proportion of successful assays that detected TB decreased significantly from 13% in 2016 to 7% in 2017 (a 46% decrease, P < 0.001); this phenomenon was observed in all types of hospital. The proportion of persons detected with rifampicin-resistant TB was similar between hospitals (4% in 2016 and 3% in 2017). The proportion of registered TB cases with bacteriological confirmation increased from 48% in 2016 to 53% in 2017 (P = 0.04). Conclusion: Xpert use in all presumptive TB patients led to a significant increase in assay numbers and utilisation of Xpert instruments, resulting in more bacteriological confirmation of cases.
