Acute clinical deterioration and consumer escalation in the hospital setting: A literature review

Abstract

Background: Consumer escalation systems that allow patients and/or their family/carers to escalate concerns about clinical deterioration have been proposed as a way of enhancing patient safety. However, evidence to guide implementation or to support system effectiveness remains unclear.

Aim: To critically evaluate the current evidence surrounding consumer escalation within the context of clinical deterioration to identify the strengths, weaknesses and gaps in existing knowledge, essential themes, and directions for further investigation.

Method: Database searches were conducted within Cumulative Index of Nursing and Allied Health Literature, PubMed, and the Cochrane Library for articles directly relating to consumer escalation systems published, in English, within the previous 10 year-period. Titles and abstracts were screened and relevant full-text articles included. Content was examined to identify breadth of knowledge, essential themes, and the effectiveness of current systems.

Results: 27 articles, containing a mixture of both quantitative and qualitative findings, were identified. Within the context of limitations in the overall depth and quality of current evidence, four key areas (relating to consumer understanding and awareness of clinical deterioration, confidence and ability to escalate concerns, education, and staff attitudes) were identified as potentially critical to the foundation, functioning, and success of consumer escalation systems. Consumer escalation processes may contribute positive effects beyond mortality rates; however, an agreed method of assessing effectiveness remains undetermined.

Conclusions: The ability of consumer escalation processes to achieve their underlying goals is still to be adequately assessed. Further research is required to inform how to best implement, support and optimise consumer escalation systems.
