CHAI ORS/Zinc CEA - updated costs January 2024 (public)

	A	B	C	D
1	Simple CEA
2		Estimated cost-effectiveness of program during RCT period	Estimated cost-effectiveness of program at scale	Notes
3	Grant size (excluding evaluation costs)	$4,402,150	$2,978,011
4	Child mortality benefits
5	Number of children in households eligible to receive free ORS and zinc	1,511,420	1,511,420
6	Cost to NGO per child provided with ORS and zinc	$2.91	$1.970	Calc
7	Percentage point increase in number using ORS	17ppt	17ppt	From "CEA" tab
8	Percent of children using ORS/zinc for diarrhea in intervention	63%	63%	From "CEA" tab
9	Mortality rate directly and indirectly related to diarrhea among those who do not use ORS	1.3%	1.2%	From "CEA" tab
10	Reduction in mortality rate due to ORS	60%	60%	From "CEA" tab
11	Number of deaths averted	1,995	1,821	Calc
12	$ / death averted	$2,206	$1,635	Calc
13	Moral weight for each death averted based on age distribution of diarrheal mortality	113	113	From "CEA" tab
14	Initial cost-effectiveness estimate	15	21	Calc
15	Benefit streams (% of total)
16	Child mortality benefits	90%	90%	From "CEA" tab
17	Development effects	2%	2%	From "CEA" tab
18	Medical costs averted	8%	8%	From "CEA" tab
19	Additional upside and downside adjustments
20	Excluded effects	1.00	1.00	From "CEA" tab
21	Downstream costs to government incurred as a result of funding to NGO (leveraging)	1.00	1.00	Our main CEA incorporates downstream costs incurred by governments as a result of ORS. This parameter is estimated by removing any downstream costs to government and estimating how much lower cost-effectiveness is in our main CEA, compared to when these downstream costs are removed. It is a rough approximation, so there is a small difference between the final cost-effectiveness noted on this tab and on our main CEA tab. See the "No leveraging_CEA" tab for calculations.
22	Chance that other funders fund similar programs without us (funging)	0.93	0.92	Our main CEA incorporates the probability that our funders fund ORS without our funding. This parameter is estimated by removing that possibility and estimating how much lower cost-effectiveness is in our main CEA, compared to when the possibility of funging is removed. It is a rough approximation, so there is a small difference between the final cost-effectiveness noted on this tab and on our main CEA tab. See the "No funging_CEA" tab for calculations.
23	Additional benefits and adjustments	1.0	1.0	Calc
24	Final cost-effectiveness (after all adjustments)	16	21	Calc
