The impact of telemedicine enabled pre-hospital triage in acute stroke – a protocol for a mixed methods systematic review

Abstract

Introduction Increasing access to thrombolysis and thrombectomy through improved pathway organisation remains a health service challenge that requires contextualisation to the geographic, demographic and resourcing status of any regional stroke service. Pre-hospital delays or delays during inter-hospital transfers can result in patients being outside the window for one or both interventions. Pre-hospital triage using technology-enabled interdisciplinary communication networks may facilitate rapid individualized care decisions, permitting streamlined care pathways to hospital sites most appropriate to their clinical presentation and history in the first instance. Understanding the experience of those involved in efforts to improve or reorganise care may help to explain the impact observed. Objectives 1. To review the impact of pre-hospital telemedicine enabled workflow intervention strategies on patient outcomes and on service process metrics in hyper-acute stroke care 2. To examine how the experience of those involved in providing or receiving such interventions might identify key characteristics of effective interventions Inclusion criteria Quantitative, qualitative and primary mixed methods studies will be included. Quantitative studies will assess effectiveness of telemedicine-enabled interventions that facilitate pre-hospital acute stroke triage. Intervention effects on functional outcomes of patients, on intervention rates and on key time metrics in hyperacute stroke care will be assessed. Qualitative studies will explore the experiences of people involved in or impacted by these interventions. Methods and analysis A convergent segregated mixed methods systematic review will synthesise and integrate primary qualitative, quantitative and mixed methods studies using the Joanna Briggs Institute methodology. Database searches will include OVID (MEDLINE), EMBASE, The Cochrane Library, CINAHL and Web of Science. Critical appraisal will include the Mixed Methods Assessment Tool. Results of quantitative studies and findings of qualitative studies will be integrated and configured to explore and contextualize each single method synthesis.
