Overview
IRD Global applied Time-Driven Activity-Based Costing (TDABC) to evaluate the cost of integrating mental health services within TB care in low-resource settings. Conducted as part of the Integrated Practice Unit (IPU) study funded by Harvard Medical School – Center for Global Health Delivery (Dubai), the program provides evidence on the time, resource use, and financial requirements of delivering mental health support alongside routine TB care. The study offers a scalable blueprint for cost-effective mental health integration, supporting policymakers and implementers in optimizing care delivery. The TDABC study was conducted at TB and Lung Health Centres in Malir and Korangi, serving low socio-economic populations with high TB burden and limited access to mental health services.

Our Approach: Delivery
IRD employed TDABC methodology to determine the cost and feasibility of integrating mental health services within TB care.
- Process mapping: Detailed care cycles at each Integrated Practice Unit (IPU) were broken down into discrete activities.
- Data collection: Time spent per activity, resource allocation, and direct and indirect costs were recorded and analyzed.
- Cost calculation: Per-minute costs were used to calculate total per-patient costs and the marginal cost of integrating mental health support.
- Flexible and scalable: The methodology allowed assessment across different provider settings and provided evidence for decision-making at facility, program, and policy levels.
This approach produced actionable insights on both financial and time investments required to integrate mental health into TB care.
