Identifying multidrug resistance in previously treated tuberculosis patients: A mixed-methods study in Cambodia

摘要

SETTING: Previously treated tuberculosis (TB) patients are a priority for drug susceptibility testing (DST) to identify cases with multidrug-resistant TB (MDR-TB). A Cambodia study found that one third of smearpositive previously treated patients had DST results.OBJECTIVE: To quantify the gaps in the detection of MDR-TB in previously treated TB patients in Cambodia, and describe health workers' perspectives on barriers, facilitators and potential interventions.
