Abstract

BACKGROUND: The World Health Organisation (WHO) introduced the twelve early warning indicators for monitoring and evaluating drug Procurement and Supply management (PSM) systems, intended to prevent drug stock-outs and overstocking. Nigeria--one of the high Multi Drug Resistant Tuberculosis (MDR-TB) burden countries, scaled-up treatment in 2012 with the concurrent implementation of a PSM system. METHOD: We evaluated how well this system functioned using the WHO indicators, including all seven MDR-TB treatment centres in the country that were functional throughout 2013. RESULTS: The quantity of MDR-TB drugs ordered for 2013 matched the annual forecast and all central orders placed during the year were delivered in full and on time. Drug consumption was 81%-106% of the quantity allocated for routine consumption. Timely submission of complete inventory reports ranged from 86-100%, late submissions being 5-15 days late. Forty to 71% of treatment centres placed a drug order when stock was below the minimum level of three months. The proportion of drug orders received at the treatment centres in full and on time ranged from 29-80%, late orders being 1-19 days late. CONCLUSION: The PSM was found to be performing well in terms of forecasting and procurement of MDR-TB drugs, but there were shortcomings in drug distribution, reporting at treatment centre level and in drug order placements. Despite these gaps, there were no stock outs. These findings indicate that where it matters most, namely ensuring that no drug stock outs affect patient management, the PSM system is effective. Addressing the observed shortcomings will help to strengthen the existing PSM system in anticipation of a growing MDR-TB case burden in the country.

  • Most of the data, including those from multiple centres such as the seven multi-drug resistant tuberculosis centres, were more likely to be from urban areas, and thus less likely to be nationally representative.

    “Nonetheless, most of the data, including those from multiple centres, for example, the seven multi-drug resistant tuberculosis (MDR-TB) centres [24] were more likely to be from urban areas, and, thus, less likely to be nationally representative.”
  • Many reviewed studies used data from multiple centres across the country or population-based surveys, and thus may be nationally representative.

    “Many of the reviewed studies used data from multiple centres across the country (or population-based surveys) [3, 8, 15, 20, 22–24, 28, 31, 33, 34, 37, 38], and thus, maybe nationally representative.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
