What factors are considered key in determining the cost-effectiveness of INH treatment?

The key factors in determining the cost-effectiveness of INH (isoniazid) treatment primarily focus on the aspects of therapy length, patient adherence, and the risk of transmission.

Length of therapy is critical because longer treatment durations can increase costs but may also reduce the likelihood of developing resistance or experiencing treatment failure. This relationship between duration and outcomes impacts the overall economic assessment of the intervention.

Patient adherence is equally important, as higher levels of adherence lead to better treatment outcomes and reduced risks of transmission. When patients stick to their medication regimen, it decreases the potential for further spread of tuberculosis, which contributes to overall public health savings. Poor adherence can lead to more complicated cases that require extensive and expensive treatments, thereby affecting cost-effectiveness negatively.

The risk of transmission is another crucial element. INH treatment aims to reduce the incidence of tuberculosis, which has significant public health implications. Evaluating how effectively the treatment minimizes transmission risks helps to justify the investment in the medication from a broader health system perspective.

In contrast, other options focus on factors that may influence treatment but do not directly relate to the core principles of cost-effectiveness in clinical practice. For instance, medication cost, while important, is not sufficient on its own without considering how treatment length, adherence
