Utilisation rates* of Xpert® MTB/RIF instruments per month in Manicaland Province, Zimbabwe, January–June 2016 and January–June 2017. The instrument was non-functional in two hospitals (Birchenough and Chipinge) between March and May 2016 and in two hospitals (Makoni and Bonda) between April and May 2017. *Utilisation rates were calculated by dividing the total number of assays by the total number of expected assays. The number of expected assays per instrument per month was 264, based on a four-module machine with a throughput of 12 assays/day and an average of 22 working days/month. An 8 h working day model was assumed.
