ObjectivesHigh-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.ResultsA 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.ConclusionsClinical practice guidelines for hypertensive disorders of pregnancy vary significantly in quality and with respect to assessment of preventive measures.
Background How the surgical stabilization of rib fractures after trauma affects the development of acute respiratory distress syndrome and impacts survival has yet to be determined in a large database. We hypothesized that surgical stabilization of rib fractures would not decrease the incidence of acute respiratory distress syndrome. Methods The National Trauma Data Bank was queried for all traumatic rib fractures in 2016. Patients were divided into groups with single rib fractures, multiple rib fractures, and flail chest. Nonoperative therapy was compared with stabilization of rib fractures of 1 to 2 ribs or 3+ ribs. Results There were 114,972 total patients with rib fractures meeting inclusion criteria, with 5,106 (4.4%) having flail chest, 24,726 (21.5%) having single rib fractures, and 85,140 (74.1%) having multiple rib fractures. Those with flail chest (15.9%) were most likely to get rib plating in comparison to multiple rib fractures (0.9%) and single rib fractures (0.2%); P < .001. On logistic regression, surgical stabilization of rib fractures 1 to 2 ribs (odds ratio: 0.17, 95% confidence interval: 0.10–0.28) or 3+ ribs (odds ratio: 0.17, 95% confidence interval: 0.11–0.28), with nonoperative therapy as the reference was associated with survival. Variables associated with mortality included increasing age, male sex, increasing injury severity score, decreased Glasgow coma scale, requirement of transfusions, and hypotension on admission. Surgical stabilization of rib fractures 3+ ribs (odds ratio: 2.30, 95% confidence interval: 1.58–3.37) was associated with acute respiratory distress syndrome but not 1 to 2 ribs (odd ratio: 1.55, 95% confidence interval: 0.97–2.48). On logistic regression of only patients with flail chest, stabilization of rib fractures was associated with decreased mortality but not increased risk of acute respiratory distress syndrome. Conclusion The increased risk of acute respiratory distress syndrome should be considered in the preoperative assessment for stabilization of rib fractures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
