Expanded state-funded family planning services: estimating pregnancies averted by the Family PACT Program in California, 1997-1998.

OBJECTIVES The California Family Planning, Access, Care, and Treatment Program was implemented in 1997 to provide family planning services for uninsured, low-income women and men. We estimated the impact on fertility of providing 500 000 women with contraceptives. METHODS Paid claims and medical record review data were used to estimate pregnancies averted. Pregnancies women experienced while enrolled in the program and pregnancies they would have experienced given methods used before enrollment were modeled as a Markov process. RESULTS One year of Family Planning, Access, Care, and Treatment services averted an estimated 108 000 unintended pregnancies that would have resulted in 50 000 unintended births and 41 000 induced abortions. CONCLUSIONS Providing contraceptives to low income, medically indigent women significantly reduced the number of unintended pregnancies in California.
