| Abstract |
There are significant delays in initiation of multidrug-resistant tuberculosis (MDR -TB) treatment. The Xpert MTB/RIF test has been shown to reduce the time to diagnosis and treatment of MDR-TB predominantly in urban centres. This study describes the time to treatment of MDR-TB and the effect of Xpert MTB/RIF on time to treatment in a deprived rural area in South Africa. This was a retrospective cohort study analysing the medical records of patients diagnosed with MDR-TB in King Sabata Dalindyebo Sub-District between 2009 and 2014. Numerical data were reported using the Kruskal-Wallis and Wilcoxon sum rank tests and categorical data compared using the two-sample test of proportions. Of the 342 patients with MDR-TB identified, 285 were eligible for analysis, of whom 145 (61.4%) were HIV positive. The median time from sputum collection to MDR-TB diagnosis was 27 days (IQR: 2-45) and differed significantly between diagnostic modalities: Xpert MTB/RIF, 1 day (IQR: 1-4; n = 114: p < 0.0001); Line Probe Assay 12 days (IQR: 8-21; n = 28; p < 0.0001); and culture/phenotypic drug sensitivity testing 45 days (IQR: 39-59; n = 143: p < 0.0001). The time from diagnosis to treatment initiation was 14 days (IQR: 8-27) and did not differ significantly between diagnostic modality. The median time from sputum collection to treatment initiation was 49 days (IQR: 20-69) but differed significantly between diagnostic modalities: Xpert MTB/RIF, 18 days (IQR: 11-27; n = 114; p < 0.0001); Line Probe Assay 29 days (IQR: 14.5-53; n = 28; p < 0.0001); and culture/phenotypic drug sensitivity, 64 days (IQR: 50-103; n = 143: P < 0.0001). Age, sex and HIV status did not influence the time intervals. Xpert MTB/RIF significantly reduced the time to MDR-TB treatment in a deprived rural setting as a result of a reduced time to diagnosis. However, the national target of five days was not achieved. Further research is needed to explore and address programmatic and patient-related challenges contributing to delayed treatment initiation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 08 July 2017.
All research outputs
#17,890,958
of 22,968,808 outputs
Outputs from BMC Infectious Diseases
#5,151
of 7,708 outputs
Outputs of similar age
#292,115
of 418,425 outputs
Outputs of similar age from BMC Infectious Diseases
#119
of 167 outputs
Altmetric has tracked 22,968,808 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 7,708 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 9.6. This one is in the 26th percentile – i.e., 26% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 418,425 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 167 others from the same source and published within six weeks on either side of this one. This one is in the 26th percentile – i.e., 26% of its contemporaries scored the same or lower than it.
