Unintended pregnancy is common in the United States, and interventions are needed to improve contraceptive use among women at higher risk of unintended pregnancy, including Latinas and women with low educational attainment.
A three-arm randomized controlled trial was conducted at two family planning sites serving low-income, predominantly Latina populations. The trial tested the efficacy of a computer-based contraceptive assessment module in increasing the proportion of patients choosing an effective method of contraception (<10 pregnancies/100 women per year, typical use). Participants were randomized to complete the module and receive tailored health materials, to complete the module and receive generic health materials, or to a control condition.
In intent-to-treat analyses adjusted for recruitment site (n=2231), family planning patients who used the module were significantly more likely to choose an effective contraceptive method: 75% among those who received tailored materials [odds ratio (OR)=1.56; 95% confidence interval (CI): 1.23-1.98] and 78% among those who received generic materials (OR=1.74; 95% CI: 1.35-2.25), compared to 65% among control arm participants.
The findings support prior research suggesting that patient-centered interventions can positively influence contraceptive method choice.
在美国，意外怀孕很常见，需要采取干预措施来提高有较高意外怀孕风险的女性（包括拉丁裔和受教育程度较低的女性）的避孕措施使用率。
这项三臂随机对照试验在两个为低收入、以拉丁裔为主的人群提供服务的计划生育点进行。该试验测试了基于计算机的避孕评估模块在增加选择有效避孕方法（每年每 100 名女性<10 例妊娠，典型使用）的患者比例方面的效果。参与者被随机分配到完成模块并接受针对性健康材料、完成模块并接受通用健康材料或对照组。
在按招募地点进行意向治疗分析（n=2231）中，使用该模块的计划生育患者选择有效避孕方法的可能性显著增加：接受针对性材料的患者中为 75%（比值比[OR]=1.56；95%置信区间[CI]：1.23-1.98），接受通用材料的患者中为 78%（OR=1.74；95% CI：1.35-2.25），而对照组参与者中为 65%。
这些发现支持了先前的研究，表明以患者为中心的干预措施可以积极影响避孕方法的选择。
