Perspectives | Societal and healthcare sector. The healthcare sector costs will include payer/provider costs as well as costs currently covered by the SAIA project budget that would be absorbed into the MOH budget at national scale-up. |
Cost estimates | Costs of SCALE SAIA-HTN delivery, including medical costs relating to screening and treatment; emphasis on measuring the change in costs (time and quantity of resources consumed) after SAIA implementation |
Data collection | 1. SAIA budget reports (project costs) 2. Integrated time-motion and out-of-pocket cost survey (patient time, costs, and % of healthcare visit spent receiving hypertension care) 3. Provider survey (triangulate estimate of % of time spent providing hypertension care) 4. Facility costing tool (prices and context-specific overheads) 5. Patient registry (utilization of hypertension services) 6. Review of government data (e.g., provider salaries, supply chain costs) |
Primary clinical outcomes | Impact on blood pressure and on the incidence of CVD, including fatal CVD; incremental cost-effectiveness ratios reported as the (1) cost per mmHg blood pressure reduction, (2) cost per patient optimally adherent; (3) cost per CVD death averted, and (4) cost per DALY averted |
Discounting | 3% in the base case; varied from 0 to 6% in sensitivity analysis |
Analytic time frame | 10 years (2025–2034) |
