The objective of this study was to measure agreement between nine
structured approaches for diagnosing childhood tuberculosis; to quantify
differences in the number of tuberculosis cases diagnosed with the
different approaches, and to determine the distribution of cases in
different categories of diagnostic certainty.
The authors investigated 1445 children aged
Tuberculosis case frequency ranged from 6.9% to 89.2% (median: 41.7).
Significant differences in case frequency (P
The study concluded that there is only slight agreement between
structured approaches for the screening and diagnosis of childhood
tuberculosis and high variability between them in terms of case yield.
Diagnostic systems that yield similarly low case frequencies may be
identifying different subpopulations of children. The study findings do
not support the routine clinical use of structured approaches for the
definitive diagnosis of childhood tuberculosis, although high-yielding
systems may be useful screening tools.
