Addressing diagnostic uncertainty and excellence in emergency care-from multicountry policy analysis to communication practice in Australian emergency departments: a multimethod study protocol.

introductionCommunication failings may compromise the diagnostic process and pose a risk to quality of care and patient safety. With a focus on emergency care settings, this project aims to examine the critical role and impact of communication in the diagnostic process, including in diagnosis-related health and research policy, and diagnostic patient-clinician interactions in emergency departments (EDs). METHODS AND ANALYSIS: This project uses a qualitatively driven multimethod design integrating findings from two research studies to gain a comprehensive understanding of the impact of context and communication on diagnostic excellence from diverse perspectives. Study 1 will map the diagnostic policy and practice landscape in Australia, New Zealand and the USA through qualitative expert interviews and policy analysis. Study 2 will investigate the communication of uncertainty in diagnostic interactions through a qualitative ethnography of two metropolitan Australian ED sites incorporating observations, field notes, video-recorded interactions, semistructured interviews and written medical documentation, including linguistic analysis of recorded diagnostic interactions and written documentation. This study will also feature a description of clinician, patient and carer perspectives on, and involvement in, interpersonal diagnostic interactions and will provide crucial new insights into the impact of communicating diagnostic uncertainty for these groups. Project-spanning patient and stakeholder involvement strategies will build research capacity among healthcare consumers via educational workshops, engage with community stakeholders in analysis and build consensus among stakeholders. ETHICS AND DISSEMINATION: The project has received ethical approvals from the Human Research Ethics Committee at ACT Health, Northern Sydney Local Health District and the Australian National University. Findings will be disseminated to academic peers, clinicians and healthcare consumers, health policy-makers and the general public, using local and international academic and consumer channels (journals, evidence briefs and conferences) and outreach activities (workshops and seminars).
