Thesis Name

A comparative study on the efficacy of various patient deterioration early warning tools used in four regional Queensland hospitals

Thesis Abstract

Numerous Early Warning Systems (EWS) have been implemented in hospitals to better identify patients at risk of deterioration. The four Central Queensland Mercy Health (CQMH) hospitals adopted various EWS in 2015. A retrospective case-control study is proposed to determine the efficacy of the various EWS used by CQMH. Eleven EWS used in Australia and a British EWS called NEWS, will be included in the study. This will be the first quantitative EWS validation study undertaken in Queensland. A time-trend analysis of patient vital signs will serve to identify when patient deterioration first becomes apparent which may help to inform medical practice.

Why my research is important/Impacts

This is the first such project undertaken using patient data from smaller regional private health facilities. The lack of specialist care and high level ICU in such regional medical facilities makes it all the more important that the nursing staff are well equipped to recognise and react to the deteriorating patient, using the tools best suited for their patient cohort. The findings of this project will help to guide nursing practice in these regional hospitals and will be the first quantitative validation study on the early warning systems used throughout Australian medical facilities.
