This executive summary presents in brief the current evidence assessed in the clinical practice guideline prepared by the Canadian Hypertensive Disorders of Pregnancy Working Group and published by Pregnancy Hypertension (http://www.pregnancyhypertension.org/article/S2210-7789(14)00004-X/fulltext) to provide a reasonable approach to the diagnosis, evaluation, and treatment of the hypertensive disorders of pregnancy.
Published literature was retrieved through searches of Medline, CINAHL, and The Cochrane Library in March 2012 using appropriate controlled vocabulary (e.g., pregnancy, hypertension, pre-eclampsia, pregnancy toxemias) and key words (e.g., diagnosis, evaluation, classification, prediction, prevention, prognosis, treatment, postpartum follow-up). Results were restricted to systematic reviews, randomized control trials, controlled clinical trials, and observational studies published in French or English between January 2006 and February 2012. Searches were updated on a regular basis and incorporated in the guideline to September 2013. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.
The quality of evidence in the guideline summarized here was rated using the criteria described in the Report of the Canadian Task Force on Preventative Health Care (Table 1).
本执行摘要简要介绍了加拿大妊娠期高血压疾病工作组编写并由《妊娠高血压》（http://www.pregnancyhypertension.org/article/S2210-7789(14)00004-X/fulltext）发表的临床实践指南中评估的当前证据，以提供一种合理的方法来诊断、评估和治疗妊娠期高血压疾病。
2012年3月通过检索Medline、CINAHL和考克兰图书馆获取已发表的文献，使用了适当的控制词汇（如妊娠、高血压、先兆子痫、妊娠中毒症）和关键词（如诊断、评估、分类、预测、预防、预后、治疗、产后随访）。结果仅限于2006年1月至2012年2月期间以法语或英语发表的系统评价、随机对照试验、对照临床试验和观察性研究。检索定期更新，并纳入截至2013年9月的指南中。通过搜索卫生技术评估和卫生技术相关机构网站、临床实践指南汇编、临床试验注册库以及国家和国际医学专业协会来识别灰色（未发表）文献。
此处总结的指南中的证据质量使用加拿大预防性医疗保健特别工作组报告中描述的标准进行评级（表1）。
