Re-inventing adherence: toward a patient-centered model of care for drug-resistant tuberculosis and HIV

Abstract

Background: Despite renewed focus on molecular tuberculosis (TB) diagnostics and new antimycobacterial agents, treatment outcomes for patients co-infected with drug-resistant TB and human immunodeficiency virus (HIV) remain dismal, in part due to lack of focus on medication adherence as part of a patient-centered continuum of care.

Objective: To review current barriers to drug-resistant TB-HIV treatment and propose an alternative model to conventional approaches to treatment support.

Discussion: Current national TB control programs rely heavily on directly observed therapy (DOT) as the centerpiece of treatment delivery and adherence support. Medication adherence and care for drug-resistant TB-HIV could be improved by fully implementing team-based patient-centered care, empowering patients through counseling and support, maintaining a rights-based approach while acknowledging the responsibility of health care systems in providing comprehensive care, and prioritizing critical research gaps.

Conclusion: It is time to re-invent our understanding of adherence in drug-resistant TB and HIV by focusing attention on the complex clinical, behavioral, social, and structural needs of affected patients and communities.

The continuum of DR-TB/HIV care defines the processes and linkages that comprise optimal care for MDR-/XDR-TB/HIV. The y-axis represents patients retained in care; the x-axis represents the stages of the continuum; the arrows represent the linkages in the continuum. The box below defines tasks and processes that occur at each stage. TB = tuberculosis; HIV = human immunodeficiency virus; DR-TB = drug-resistant TB; VL = viral load; DST = drug susceptibility testing; MDR-TB = multidrug-resistant TB; XDR-TB = extensively drug-resistant TB.
