Interactional misalignment in the UK NHS111 healthcare telephone triage service

Abstract Background A recent review of primary care serious incidents suggests that diagnosis and assessment problems, underpinned by communication failures, involving the UK telephone triage service, NHS111, may contribute to patient harm. Methods The present study utilised conversation analysis to address the lack of evaluative research examining the NHS111 system and in particular interactions between system components (e.g., call handler, computerized decision support system, patients/caller). Results Analysis of audio recorded call interactions revealed interactional misalignment across four mapped call phases (i.e., eliciting caller details, establishing reason for call, completing the Pathways assessment, and agreeing the outcome). This misalignment has the capacity to increase the risk of system failure, particularly in relation to assessment problems and issues related to the accurate transfer of care advice. Our analysis suggests that efforts to enhance the NHS111 system, similar telehealth services, and patient safety management more generally, should shift their focus from a limited set of individual components towards a system-specific interactionist perspective encompassing all elements. Conclusions Further evaluative research is required in order to build a comprehensive evidence-base concerning the multiple interacting factors influencing patient safety in the NHS111 system.
