Outcomes of surrogate pregnancies in California and hospital economics of surrogate maternity and newborn care

Table 1 Characteristics of Surrogate Women prior to surrogate pregnancy: mean, range and SD

Surrogates	Age (yr)	Gravidity	Parity
n = 45	27	2.7	2.3
Range	20-43	1-8	1-7
SD	4.6	3.6	3.3

Table 2 Maternal characteristics for surrogate pregnancies related to singleton, twin or triplet delivery

Surrogates	Maternity LOS (d)	Ratio	Hospital charges(± SD)	Ratio
Singleton births (n = 20)	4.2 (1.2)	1.3	$31115	1.2
Twin births (22)	3.5 (0.8)	1.1	$29692 ± 11892	1.1
Triplet births	15	4.7	$102673	3.8

Hospital Length of Maternity Stay (LOS) and charges compare surrogate carrier charges related to LOS and maternity charges for naturally conceived term infants requiring normal nursery care (mean ± SD).

Table 3 Infant characteristics after birth from surrogate pregnancy

Infant(s)	Birth weight	GA	LOS	Hospital charges	Ratio
Singleton (n = 19)	3798.3 ± 832.9	35.9 ± 2.9	11 ± 3	$154874 ± 326415	26.2
Twins (n = 44)	2151.5 ± 750.5	33.8 ± 4.3	12.7 ± 4	$154885 ± 339442	26.2
Triplets (n = 3)	1337.2 ± 91.8	30.0 ± 0	75.0 ± 0	$1025927 ± 99097	173.8

Hospital charges are expressed as a ratio of hospital charges for per infant compared to hospital charges for a term infant provided care in the normal nursery (mean ± SD). GA: Gestational age; LOS: Length of stay.
