Abstract
SETTING: The emergence of multidrug-resistant tuberculosis (MDR-TB) threatens the ongoing control of tuberculosis (TB). The Australian state of New South Wales (NSW) has low TB and MDR-TB incidence.
OBJECTIVE: To examine the epidemiology and the clinical and public health management of MDR-TB in NSW.
DESIGN: A retrospective case-series analysis of MDR-TB diagnosed in NSW between 1999 and 2010 was undertaken. A standardised questionnaire was used to collect information from the public health surveillance system, medical records and the State Mycobacterium Reference Laboratory about clinical features, drug susceptibility, treatment regimens, hospitalisation, risk factors for tuberculous infection, contact tracing and patient outcomes.
RESULTS: Fifty-five cases of culture-confirmed MDR-TB, including two cases of extensively drug-resistant TB, were diagnosed. All cases were reviewed by an expert management panel. Fifty cases (91%) were foreign-born, and 50 cases (91%) had fully supervised treatment. Of the 55 cases, 46 (84%) successfully completed treatment, 3 (5%) died of TB and 3 (5%) required surgery. No MDR-TB cases were reported among contacts.
CONCLUSION: Using a multidisciplinary, expert guided, case-management approach, the NSW TB Control Program achieved excellent MDR-TB outcomes. The impact of global increases in MDR-TB requires sustained commitment to TB in all settings.
