MORA, Guillermo et al. Syncope and risk scales: What evidence do we have?. Rev. Colomb. Cardiol. [online]. 2011, vol.18, n.6, pp.330-339. ISSN 0120-5633.

Objective: perform a review of the existing risk scales to predict adverse events associated with syncope. Method: we conducted a search of MEDLINE, EMBASE and Cochrane Database of Systematic Reviews using the keywords related to clinical prediction rules (algorithms, multivariate analysis, clinical prediction guides, scales, logistic models, risk assessment) and syncope. Additionally, literature was searched using the snowball strategy. Results: we found nine scales that associated syncope with prediction of adverse events. We found differences in the criteria for defining risk, the outcome variables, the study population, the use of a prospective or retrospective strategy and the follow-up time. Conclusions: although there are several scales for the definition of risk facing the patient admitted with syncope to the ER, there is no evidence that any one is superior to another, have little external validity and have not been applied in our environment.

Keywords : clinical prediction rules; syncope.
