Quality of drug-resistant tuberculosis care: Gaps and solutions

Drug-resistant forms of tuberculosis (DR-TB) are a significant cause of global morbidity and mortality and the treatment of DR-TB is characterized by long and toxic regimens that result in low rates of cure. There are few formal studies documenting the quality of DR-TB treatment services provided globally, but the limited data that do exist show there is a quality crisis in the field. This paper reviews current issues impacting quality of care in DR-TB, including within the areas of patient-centeredness, safety, effectiveness and equity. Specific issues affecting DR-TB quality of care include: 1) the use of regimens with limited efficacy, significant toxicity, and high pill burden; 2) standardized treatment without drug susceptibility testing; 3) non-quality assured medications and drug stock outs; 4) lack of access to newer and repurposed drugs; 5) high rates of adverse events coupled with minimal monitoring and management; 6) care provided by multiple providers in the private sector; 7) depression, anxiety, and stress; and 8) stigma and discrimination. The paper discusses potential ways to improve quality in each of these areas and concludes that many of these issues arise from the traditional "public health approach" to TB and will only transformed when a human-rights based approach is put into practice.
