Sayana Press interim CEA

	A	B	C	D
1			Source	Notes
2	Hypothetical cohort of women who begin using Sayana Press	10000	Arbitrary assumption, does not affect results
3	Total cost of injectable contraceptives per person, per year	$9.14	Singh and Darroch 2012, Pg 12, Table 3	Injectible annualised cost for Africa, " †We assumed users need an annual average of four three-month injections, 13 one-month injections, 14 pill cycles or 77 condoms. ‡Supplies include gloves, antiseptic, local anaesthesia, syringes, sutures and dressings. §Labor (community health worker, nurse/midwife, general physician, obstetrician) costs include counseling on family planning, STI/HIV prevention and gender-based violence; physical exams; contraceptive procedures; and follow-up and resupply visits."
4	Total cost for hypothetical cohort for one year	$91,400	Calculation
5
6	% of doses administered to new users of family planning	28%	See "Proportion of doses adminstered to new users" sheet	Weighted average of doses of Sayana Press adminstered to new users of family plannng in pilot programs. We wish to estimate the number of women who get access to Sayana Press through the programs and would not have used modern contraception otherwise. "New users" is an imperfect proxy for this number; it appears plausible to us that it might be a significant overestimate (if, for example, the programs were implemented in areas where the use of modern contraceptives is generally increasing), or it may be a significant underestimate (if the programs are implemented in areas where some women had access to other forms of modern contraception in the past, then lost access).
7	Cost per person-year of coverage, new users only	$32	Calculation
8
9	Unintended pregnancies per 1,000 women aged 15-44 per year, Africa, 2012	80	Sedgh, Singh, and Hussain 2014, Pg 307, Table 2
10	% of these pregnancies among women who do not use modern contraception	81%	Singh, Darroch, and Ashford 2014, Pg 13, Figure 2.4.
11	Expected number of unintended pregnancies among new users of family planning in cohort after one year, in absence of Sayana Press	648	Calculation
12	Injectable Depo-provera contraceptive effectiveness with typical use	93%	Stover et al 2016, Pg 99, Table 6.1
13	Expected number of unintended pregnancies among new users of family planning in cohort after one year, with typical use of Sayana Press	45	Calculation
14	Unintended pregnancies averted	603	Calculation
15	Cost per unintended pregnancy averted	$152	Calculation
16
17	Cost per miscarriage averted	$1,083	Sedgh, Singh, and Hussain 2014, Pg 310, Table 4	Calculated using the "Percentage distribution of unintended pregnancy outcome" for Africa
18	Cost per abortion averted	$460	Sedgh, Singh, and Hussain 2014, Pg 310, Table 4	Calculated using the "Percentage distribution of unintended pregnancy outcome" for Africa
19	Cost per unwanted or mistimed birth averted	$286	Sedgh, Singh, and Hussain 2014, Pg 310, Table 4	Calculated using the "Percentage distribution of unintended pregnancy outcome" for Africa
