Abstract
Objective: Identify in the literature the difficulties faced by nurses in the classification of risk in the emergency and emergency service. Methods: An integrative literature review study was carried out with the search for data from the Virtual Health Library, LILACS, BVS and SCIELO having as descriptors, reception, nursing and emergency. Included articles that addressed the theme, published in English and Portuguese in the period 2014-2018. Results: 152 original articles were identified between 2014 and 2018, of which 10 were selected. All material was analyzed using the Content Analysis technique. Two thematic categories emerged: Reception with risk classification and the Difficulties of Nurses in the accomplishment of the classification of risk. Final considerations: It was found that although the nurse is responsible for the classification of risk, this service presents several difficulties as the lack of training of nurses to carry out the risk classification and applicability / evaluation of the protocol; deficit of material resources; disagreement about the Risk Classification with what is advocated by the National Humanization Policy.
