BACKGROUND: Timeously completing tuberculosis (TB) treatment is a key to optimal health outcomes. Suboptimal treatment refill patterns, even among those categorized as "treatment success," may portend unfavorable outcomes.
METHODS: Using patient-level medication refill data, latent-class mixed modeling was used to identify longitudinal trajectories of care engagement among TB patients achieving programmatic treatment success. Logistic regression was conducted to investigate participant-level characteristics associated with trajectory class membership.
RESULTS: Among 548 participants, we identified 3 trajectories: Class 1 (consistent engagement; 84.1%), Class 2 (suboptimal engagement after 2 months; 7.7%), and Class 3 (suboptimal engagement from initiation; 8.2%). At treatment completion, Classes 1-3 accumulated 9.7 (95% confidence interval [CI]: 7.4-11.8), 68.4 (60.4-76.9), and 55.5 (48.1-62.7) missed refill days, respectively. In gender-stratified models, men exhibited all 3 trajectories (83.1%, 7.4%, and 9.5%, respectively), and accumulated 10.6 (7.8-13.3), 61.0 (50.2-71.3), and 62.31 (53.14-71.72) missed refill days, respectively. Women exhibited only Classes 1 and 3 (89.5% and 10.5%, respectively) and accumulated 12.1 (7.8-16.5) and 46.9 (33.3-61.6) missed refill days, respectively. Among men, prior TB (Class 2: adjusted odds ratio [aOR] 7.44, 2.79-19.8; Class 3: aOR 2.78, 1.07-7.25) and human immunodeficiency virus-negative status (Class 3: aOR 2.72, 1.13-6.54) were associated with suboptimal trajectories. Among women, prior TB was associated with suboptimal engagement (aOR 5.22, 1.11-24.44).
CONCLUSIONS: Programmatic "treatment success" obscured heterogeneity in treatment refill patterns. Patient-centered counseling and gender-responsive interventions are needed to address treatment refill behaviors. Shorter regimens alone may not resolve suboptimal engagement, highlighting the need for flexible treatment strategies.
