Objectives: High-quality evidence-based clinical practice guidelines can guide diagnosis and treatment to optimise outcomes. The purpose of this study was to evaluate the quality and content of national and international guidelines on hypertensive disorders of pregnancy.
Data sources: The MEDLINE database, the National Guideline Clearinghouse and several international databases were searched for appropriate guidelines from the past 10 years.
Study appraisal and synthesis methods: Six guidelines met inclusion and exclusion criteria and were evaluated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument.
Results: A total of 695 records were identified and screened by two authors. Disorder definitions, classifications, preventive measures and treatment recommendations were evaluated and compared among guidelines. AGREE II results varied widely across domains and categories. Only two guidelines received consistently high ratings across domains and few demonstrated a high level of methodological rigour. Recommendations regarding classification and treatment were similar across guidelines, while assessment of preventive measures varied widely.
Conclusions: Clinical practice guidelines for hypertensive disorders of pregnancy vary significantly in quality and with respect to assessment of preventive measures.
