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.
目标
加利福尼亚计划生育、获取、护理与治疗项目于1997年实施，旨在为未参保的低收入女性和男性提供计划生育服务。我们估计了为50万名女性提供避孕药具对生育率的影响。
方法
使用付费索赔和病历审查数据来估计避免的怀孕情况。将女性在参与该项目期间经历的怀孕以及根据她们在参保前使用的方法本会经历的怀孕建模为一个马尔可夫过程。
结果
一年的计划生育、获取、护理与治疗服务估计避免了10.8万例意外怀孕，这些意外怀孕本会导致5万例意外分娩和4.1万例人工流产。
结论
为低收入、医疗贫困女性提供避孕药具显著减少了加利福尼亚州的意外怀孕数量。
