Turning the tide: Putting acute aphasia management back on the agenda through evidence-based practice

Abstract

Background: The role of speech pathologists working in the acute hospital setting has evolved away from service provision to people with aphasia and their families towards a stronger focus on dysphagia. Evidence-based practice (EBP) can be conceptualised as the integration of four streams of evidence: research-based clinical evidence, clinical expertise, patient preferences and values, and the practice context. EBP is an important tenet in current healthcare. However, it is not clear whether speech pathologists in the acute setting are using EBP to support their aphasia management. Not adopting evidence-based approaches to care has the potential to result in a negative impact on people with aphasia and their families, healthcare services, and speech pathologists, who experience a sense of dissonance related to their current service provision This paper explores acute aphasia management through an EBP lens in an attempt to better understand this dilemma. Aims: This paper applies the conceptual framework of EBP to acute aphasia management. An extensive, systematically conducted review of the international literature relating to health professionals was undertaken. The findings are presented as a narrative literature review. Main Contribution: This paper describes and evaluates how the different streams of research evidence, clinical expertise, patient preferences and values, and the practice context contribute to speech pathologists' management of acute aphasia. Further, the paper identifies current gaps in the literature and suggests a research agenda for the field. Conclusions: Little is known about how speech pathologists integrate and implement the different streams of evidence in EBP, and how these contribute to acute aphasia practice. Speech pathologists report that clinical guidelines containing low-level evidence are the main source of research information. Other sources of knowledge include colleagues, professional development events, and websites. Additional challenges to the management of people with aphasia in the acute hospital setting may be posed by the physical environment, the culture of the acute hospital setting, and the provision of leadership to support evidence-based approaches to care. The challenge of using a person-centred approach to care for people with aphasia is acknowledged. Further research exploring speech pathologists' perceptions of their role in acute aphasia management, the clinical decision-making process of speech pathologists in relation to acute aphasia management, and the experiences of people with aphasia and their families in the acute setting is required. This will allow for the design of patient-centred approaches to care, and enable the implementation of evidence-based acute aphasia management. © 2013 Copyright Taylor and Francis Group, LLC.
