Abstract; Table 3, row 'B − A', column 'Adjusted model - Coefficient'
After the policy change, the difference in mortality between the groups increased, with mortality decreasing by approximately 3% more in the treatment group compared with in the control group (coefficient: −0.03, standard error, 0.01).
Contexto
What changed: Complete exemption of the remaining 10% out-of-pocket copayment for TB medical services under National Health Insurance in July 2016. Comparison: Propensity score-matched difference-in-differences comparing health insurance beneficiaries to medical aid beneficiaries (who already had free or near-free care) before (2013–2015) vs after (2016–2018). Limits: Evaluates all-cause rather than TB-specific mortality using administrative claims data.
