研究背景：
女性孕育新生命是一生中最重要的過渡期，在懷孕過程也可能充滿了壓力
，促進懷孕婦女周產期安全，是產科護理學的重要目標。運用雲端資訊系統照護病患已成為一種趨勢，然而，目前台灣較少探討運用雲端資訊科技提供孕期婦女健康照護。

研究目的：
本研究主要目的為，探討「雲端資訊孕期自我健康管理系統」對懷孕婦女孕期壓力與自我效能之成效，以及探討使用「雲端資訊孕期自我健康管理系統」之滿意度。

研究方法：
本研究為類實驗性研究設計，研究介入措施：「雲端資訊孕期自我健康管理系統」由工程科學系與護理學系共同開發，提供實驗組婦女於孕期使用此系統，而控制組婦女提供一般性孕期健康照護，收案流程避免情境因素干擾，故先收控制組再收實驗組，以立意取樣方式，選取南部某醫學中心婦產科門診之懷孕婦女，本研究控制組有67位婦女及實驗組有68位婦女，共135人。收案時間點：懷孕婦女於16 ~ 24週進行前測，於36~38週進行後測，研究工具以孕期壓力量表、自我效能量表、孕期照護品質滿意度問卷及孕期自我照護資訊系統滿意度問卷，研究結果以SPSS17.0進行描述性統計、t檢定、One-Way ANOVA、及ANCOVA檢定等進行資料統計分析。

結果：
本研究共135位懷孕婦女參加(控制組67位婦女，實驗組68位婦女)，研究結果在組間效應方面，以ANCOVA控制前測變項，實驗組婦女在介入措施後，孕期壓力之降低(F=12.90，P＜.001)及自我效能之提升(F=17.61，P＜.001)，皆顯著優於控制組婦女。

結論/實務應用:
本研究顯示雲端資訊系統能改善懷孕婦女孕期壓力、提升自我效能及提升孕期照護滿意度，且透過雲端資訊系統可應用於臨床業務，進而提升孕期照護品質。

SUMMARY
The purpose of this study was to explore the effectiveness of cloud information system of pregnant care in prenatal women’s stress, self-efficacy. This study applied a quasi-experimental research design. A cloud information system of prenatal care self-management was developed by a professional team including Engineering Sciences and Nursing. There were two groups : experimental group(EG) and control group(CG).
A total of 135 pregnant women participated in study, this study (CG=67 ; EG=68). After controlling for pretest scores of pregnancy stress and self-efficacy, women in experimental group had significant lower pregnant stress(F= 12.90，P＜.001) and higher self-efficacy (F= 17.61，P＜.001) than had control group. This study reveals the cloud information system of prenatal care self-management can reduce the pregnant stress and enhance self-efficacy among pregnant women.

INTRODUCTION
Women’s pregnancy is the most important transition in women’s lifespan. Pregnant women may confront stresses during the period (Chou & Chen, 2001). A major goal of Obstetric nursing is to promote women`s safety during pregnancy. A applying cloud information system to patient in care has become a trend (Vujin & Milenkovic, 2012). However, few studies explored the effectiveness of applying cloud information system in health care for pregnant women in Taiwan.

MATERIALS AND MATHODS
This study applied a quasi-experimental research design. There were two groups : experimental group(EG) and control group(CG). EG received「cloud information system of prenatal care of self-management」, women in CG received general health-care. A time series procedure was applied to collect data control group was conducted first, then experimental group. A purposive sampling method was used to recruit pregnant participants. Data was collected at two time points to the pregnant participants: pregnancy 16 ~ 24 weeks (pre-test) and pregnancy 36 ~ 38 weeks (post-post). Research instruments included the Pregnancy Stress Scale、Self-efficacy Scale 、Pregnancy Care Satisfaction Questionnaire and Pregnant Care Information System Satisfaction Scale. Data analysis are performed with descriptive statistics、t-test、One-Way ANOVA and ANCOVA test by SPSS17.0.

RESULTS
A total of 135 pregnant women participated in study, this study (CG=67 ; EG=68). After controlling for pretest scores of pregnancy stress and self-efficacy, women in experimental group had significant lower pregnant stress(F= 12.90，P＜.001) (Figure 1) and higher self-efficacy (F= 17.61，P＜.001) (Figure 2) than had control group.

CONCLUSION
This study reveals the cloud information system of prenatal care self-management can reduce the pregnant stress and enhance self-efficacy among pregnant women. The empirical results show the cloud information system can be applied to pregnant care in clinical work.
