Understanding the pre-medical emergency team tier of a mature rapid response system: A content analysis of guidance documents

Abstract

Background: The pre-medical emergency team (pre-MET) tier of rapid response systems (RRSs) includes extended activation criteria to identify earlier clinical deterioration and a ward-based patient review that is undertaken by the affected patient's admitting team or covering doctors. There is limited understanding of the structure and processes of the pre-MET RRS tier that are expected to guide clinicians' actions and subsequent patient safety outcomes.

Objective: The aim of the study was to describe the structure and processes of the pre-MET RRS tier in one acute care setting.

Methods: An exploratory descriptive design involving document analysis was used. Guidance documents (policies, procedures, guidelines, charts, educational materials) were obtained from one health service with a mature, multitiered RRS in Melbourne, Australia. Documents were analysed using content analysis. Concept- and data-driven approaches were used to construct a coding frame.

Results: Nineteen guidance documents supporting the pre-MET RRS tier on general wards were analysed. The coding frame consisted of seven main categories: Defining the Pre-MET RRS Tier, Essential Resources for Operationalisation, Recognising Pre-MET Events, Pathways for Activation, Exceptions to the Rule, Clinician Responses to Pre-MET Events, and Recording Pre-MET Events. The structures and processes of the pre-MET RRS tier were largely consistent with national guidelines, but there were internal inconsistencies in pre-MET activation criteria and unclear recommendations for modifying criteria. Pathways for activating the pre-MET RRS tier were complex and involved many steps, including validation processes before escalation of care to doctors. Responses to pre-MET events were seldom aligned to specific clinician types or groups, with nurses and allied health clinicians being under-represented.

Conclusions: We identified opportunities to improve guidance documents supporting the pre-MET RRS tier that may assist other health services engaged in planning or evaluating pre-MET strategies. Further research is needed to understand clinicians' use of the pre-MET RRS tier to inform targeted strategies to optimise its design and implementation.
