Exploring interdisciplinary communication pathways for escalating pre-medical emergency team deterioration: a mixed-methods study.

Objective: To explore clinicians' use and perceptions of interdisciplinary communication pathways for escalating care within the pre-medical emergency team (pre-MET) tier of rapid response systems. Method: A sequential mixed-methods study was conducted using observations and interviews. Participants were clinicians (nurses, allied health, doctors) caring for orthopaedic and general medicine patients at one hospital. Descriptive and thematic analyses were conducted. Results: Escalation practices were observed for 13 of 27 pre-MET events. Leading communication methods for escalating pre-MET events were alphanumeric pagers (61.5%) and in-person discussions (30.8%). Seven escalated pre-MET events led to bedside pre-MET reviews by doctors. Clinician interviews (n = 29) culminated in two themes: challenges in escalation of care, and navigating information gaps. Clinicians reported deficiencies in communication methods for escalating care that hindered interdisciplinary communication and clinical decision-making pertaining to pre-MET deterioration. Conclusion: Policy-defined escalation pathways were inconsistently utilised for pre-MET deterioration. Available communication methods for escalating pre-MET events inadequately fulfilled clinicians' needs. Variable perceptions of escalation pathways illuminated a lack of of a shared mental model about clinicians' roles and responsibilities. To optimise timely and appropriate management of patient deterioration, communication infrastructure and interdisciplinary collaboration must be enhanced. What is known about the topic? To promote earlier recognition of, and response to, deteriorating ward patients, Australian rapid response systems include a pre-medical emergency team (pre-MET) tier. Escalation pathways within the pre-MET tier are poorly understood. What does this paper add? Policy-defined escalation pathways were inconsistently utilised. Clinicians identified deficiencies in communication methods (e.g. alphanumeric pagers) for escalating pre-MET deterioration. Perceptions of escalation pathways illuminated a lack of of a shared mental model about clinicians' roles and responsibilities. What are the implications for practitioners? To optimise the management of pre-MET deterioration, ward-based communication infrastructure and interdisciplinary collaboration must be enhanced. [ABSTRACT FROM AUTHOR]
