To perform a literature review of key aspects of prenatal care delivery to inform new guidelines.
A comprehensive review of Ovid MEDLINE, Elsevier's Scopus, Google Scholar, and ClinicalTrials.gov.
We included studies addressing components of prenatal care delivery (visit frequency, routine pregnancy assessments, and telemedicine) that assessed maternal and neonatal health outcomes, patient experience, or care utilization in pregnant individuals with and without medical conditions. Quality was assessed using the RAND/UCLA Appropriateness Methodology approach. Articles were independently reviewed by at least two members of the study team for inclusion and data abstraction.
TABULATION, INTEGRATION, AND RESULTS: Of the 4,105 published abstracts identified, 53 studies met inclusion criteria, totaling 140,150 participants. There were no differences in maternal and neonatal outcomes among patients without medical conditions with reduced visit frequency schedules. For patients at risk of preterm birth, increased visit frequency with enhanced prenatal services was inconsistently associated with improved outcomes. Home monitoring of blood pressure and weight was feasible, but home monitoring of fetal heart tones and fundal height were not assessed. More frequent weight measurement did not lower rates of excessive weight gain. Home monitoring of blood pressure for individuals with medical conditions was feasible, accurate, and associated with lower clinic utilization. There were no differences in health outcomes for patients without medical conditions who received telemedicine visits for routine prenatal care, and patients had decreased care utilization. Telemedicine was a successful strategy for consultations among individuals with medical conditions; resulted in improved outcomes for patients with depression, diabetes, and hypertension; and had inconsistent results for patients with obesity and those at risk of preterm birth.
Existing evidence for many components of prenatal care delivery, including visit frequency, routine pregnancy assessments, and telemedicine, is limited.
对产前保健服务的关键方面进行文献回顾,为新指南提供信息。
对 Ovid MEDLINE、爱思唯尔的 Scopus、Google Scholar 和 ClinicalTrials.gov 进行全面综述。
我们纳入了评估产前保健服务交付组件(就诊频率、常规妊娠评估和远程医疗)的研究,这些组件评估了有和没有医疗条件的孕妇的母婴健康结局、患者体验或护理利用情况。使用 RAND/UCLA 适宜性方法评估质量。至少由两名研究团队成员独立审查文章,以确定是否纳入并提取数据。
列表、综合和结果:在确定的 4105 篇已发表摘要中,有 53 项研究符合纳入标准,共纳入 140150 名参与者。就诊频率减少的无医疗条件患者母婴结局无差异。对于有早产风险的患者,增加产前服务就诊频率与改善结局不一致相关。血压和体重的家庭监测是可行的,但胎儿心率和宫底高度的家庭监测没有评估。更频繁的体重测量并不能降低体重过度增加的发生率。有医疗条件的个体进行家庭血压监测是可行的、准确的,并与较低的就诊利用率相关。接受常规产前保健远程医疗就诊的无医疗条件患者健康结局无差异,患者护理利用率降低。远程医疗是有医疗条件个体咨询的成功策略;改善了抑郁、糖尿病和高血压患者的结局;肥胖患者和早产风险患者的结局不一致。
许多产前保健服务交付组件(包括就诊频率、常规妊娠评估和远程医疗)的现有证据有限。
