Improving access to preventive maternal health care using reminders: Experimental evidence from Guatemala
在危地马拉低收入地区，社区健康工作者亲自上门提醒孕妇产检，使产检率提高3.4-7.8个百分点，对高风险孕妇效果更明显。
This paper reports the results of an experiment designed to improve access to prenatal care of pregnant women in a low-resource setting. A simple intervention of timely reminders delivered in person by community health care workers was found to increase prenatal doctor visits by 3.4-7.8 percentage points. The effect was larger for women with riskier pregnancies.
