KERALA RISING · FROM EXPORTING PEOPLE TO EXPORTING IDEAS WORKED EXAMPLE: THE DOWNSTREAM-COST LOGIC Healthy Kerala will not be a large direct earner, and it should not be judged as one. Its return is in the downstream health-system costs it helps avoid. A population that screens earlier and moves more carries a lower long-run non-communicable-disease burden, and that burden is one the state already pays for, in hospital beds, in lost productivity, in the slow attrition of an ageing, diabetic population. So the arithmetic that justifies the program is not on the institution’s books at all; it is on the health system’s. A measurable rise in screening-camp attendance and donation participation, audited rather than surveyed, is worth far more to the state than the program costs to run and even though almost none of that value returns as revenue. Hospital, insurer, and corporate-wellness sponsorship cover the running cost; the real prize is the avoided cost the state would otherwise absorb in full. Failure modes and fraud controls Because this program touches the most sensitive data and the most vulnerable incentives, its controls are stricter than elsewhere and several are about protecting participants rather than the integrity of the score. 184
