DST is recommended for all culture-confirmed cases of tuberculosis.

We defined on-time reporting as DST results received during the same calendar year in which the patient\u2019s case was reported or \u22644 months after the calendar year ended and delayed reporting as DST results received after the calendar year. We compared cases with on-time, delayed, and unreported DST results by patient and tuberculosis program characteristics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The proportion of cases with reported results for all first-line antituberculosis drugs increased during 1993-2011. Reporting of pyrazinamide results was lower than reporting of other drugs. However, during 2000-2012, of 134\u2009787 tuberculosis cases reported to the National Tuberculosis Surveillance System, reporting was on time for 125\u2009855 (93.4%) cases, delayed for 5332 (4.0%) cases, and unreported for 3600 (2.7%) cases.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Despite increases in the proportion of cases with on-time DST results, delayed and unreported results persisted.
