          Abstract

          OBJECTIVE To analyze the scientific production about the validity and reliability of the Manchester Triage System (MTS) protocol. METHOD A descriptive study of an integrative literature review. Articles on the validity and reliability of the MTS developed with children and adults published between 1999 and 2013 were included. RESULTS 14 articles were selected from a total of 8438, nine of validity and five of reliability. The reliability of the MTS ranged from moderate to almost perfect, with higher intra-evaluation. Regarding validity, the results seem to point to equivalent and satisfactory sensibility and specificity levels of the MTS. The instrument proved to be a good predictor of the need for hospitalization and of hospital mortality. CONCLUSION The reliability and validity of the MTS obtained in the studies is varied. It is recommended that new studies indicate necessary modifications to the MTS so that it is more safely used by nurses.

Foram incluídos artigos sobre validade e confiabilidade do MTS, desenvolvidos com crianças e adultos, publicados entre 1999 a 2013. RESULTADOS Selecionou-se 14 artigos de um total de 8.438, sendo nove sobre validade e cinco sobre confiabilidade. A confiabilidade do MTS variou de moderada a quase perfeita, sendo maior intra-avaliadores. Quanto à validade, os resultados parecem apontar para níveis equivalentes e satisfatórios de sensibilidade e especificidade do MTS. O instrumento mostrou-se bom preditor da necessidade de internação e de mortalidade hospitalar. CONCLUSÃO A confiabilidade e validade do MTS obtidas nos estudos são variadas. Recomenda-se novos estudos que indiquem as modificações necessárias no MTS para que o mesmo seja utilizado com maior segurança pelos enfermeiros.

              Is Manchester (MTS) more than a triage system? A study of its association with mortality and admission to a large Portuguese hospital.

              The Manchester Triage System (MTS) is a 5-point triage scale used to triage patients presenting to the emergency department. It was introduced in the UK in 1996 and is now widespread, especially in Europe, and has been in use in our hospital since 2000 via a computerised protocol. A study was undertaken to determine whether the subgroups created by the application of MTS have different propensities for indirect triage outcomes such as death in the A&E department or being admitted to hospital. A database of 321 539 patients triaged during a 30-month period (from January 2005 to June 2007) was used. MTS codes, death outcomes, admission and admission route were used to estimate the proportions and association between MTS codes and the remaining variables by chi(2) univariate analysis. There was a clear association between the priority group and short-term mortality as well as with the proportion of patients admitted to hospital. The MTS provides information that extends beyond its immediate usefulness as a prioritisation mechanism. It is a powerful tool for distinguishing between patients with high and low unadjusted risk of short-term death as well as those who will stay in hospital for at least 24 h and those who will return home. Its discriminatory power is not equal for medical and surgical specialities, which may be linked to the nature of its inbuilt discriminators.
