Determining the value of TB active case-finding: current evidence and methodological considerations.

Area of Science:

• Public Health
• Health Economics
• Epidemiology

Background:

• Active case-finding (ACF) is integral to the End TB Strategy, aiming to close the global case-detection gap.
• The economic aspects and cost-effectiveness of ACF interventions are not well-understood, hindering optimal resource allocation.
• Limited and inconsistent data on ACF costs impede accurate economic evaluations and long-term impact forecasting.

Purpose of the Study:

• To highlight the need for robust economic evaluations of active case-finding (ACF) strategies.
• To emphasize the importance of collecting high-quality cost and effectiveness data for ACF interventions.
• To advocate for the integration of economic analyses into pragmatic trials for real-world ACF assessment.

Main Methods:

• Review of existing literature on the economics of active case-finding (ACF).
• Discussion on the requirements for economic evaluations within pragmatic trials.
• Emphasis on the need for linking empirical cost data with analytical models.

Main Results:

• Current data on ACF costs are limited, inconsistent, and lack standardized reporting methods.
• Pragmatic trials are valuable for assessing ACF cost-effectiveness in real-world settings but require early economic evaluation.
• Substantial additional resources and research are needed to optimize ACF implementation and affordability.

Conclusions:

• High-quality data on ACF costs and effectiveness are essential for assessing its value.
• Analytical models adapted to local settings are crucial for forecasting the long-term effects of ACF.
• Continued investment in innovative technologies and research is vital for efficient global TB control through ACF.
