Speech-language pathologists are increasingly required to demonstrate that their practice is based on evidence. While the concept of evidence-based practice has strengths, there have been some weaknesses in its application in speech-language pathology. Nevertheless, since current health care demands compliance, the profession must consider the opportunities and threats that evidence-based practice poses. This paper reviews the literature to provide an understanding of the relevance of evidence-based practice for speech-language pathology. It considers the assumptions on which definitions of evidenced-based practice rely and reviews the ways in which clinicians might base their practice on evidence. While the medical model of evidence-based practice research is controversial even in the medical field, the concept provides opportunities for the profession of speech-language pathology. Evidence-based practice has the potential to improve intervention for people with commu-nication disorders, increase resources for services and enhance perception of the profession.

“…Such restrictive criteria limit the extent to which the existing literature can be used to address questions regarding the value of aphasia treatment. On this point, we appreciate Tim Pring's (2004) appraisal of this situation in his essay entitled "Ask a silly question: Two decades of troublesome trials." We acknowledge that under ideal circumstances the best available evidence would consist of meta-analyses of high-quality randomized control trials.…”

Evaluating Single-Subject Treatment Research: Lessons Learned from the Aphasia Literature

2006

The mandate for evidence-based practice has prompted careful consideration of the weight of the scientific evidence regarding the therapeutic value of various clinical treatments. In the field of aphasia, a large number of single-subject research studies have been conducted, providing clinical outcome data that are potentially useful for clinicians and researchers; however, it has been difficult to discern the relative potency of these treatments in a standardized manner. In this paper we describe an approach to quantify treatment outcomes for single-subject research studies using effect sizes. These values provide a means to compare treatment outcomes within and between individuals, as well as to compare the relative strength of various treatments. Effect sizes also can be aggregated in order to conduct meta-analyses of specific treatment approaches. Consideration is given to optimizing research designs and providing adequate data so that the value of treatment research is maximized.

“…heterogeneity, efficacy vs effectiveness) are perpetuated, which presents barriers to building a robust evidence base. A prime example is the paper titled Ask a silly question: two decades of troublesome trials 23 which, despite including several valid pro-RCT comments, tends to be wrongly interpreted as proof that RCTs are inappropriate for SL therapy.…”

HTA NIHR Health Technology Assessment programmeThe Health Technology Assessment (HTA) programme, part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the effectiveness, costs and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined as all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care. The research findings from the HTA programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service' . The HTA programme is needs led in that it fills gaps in the evidence needed by the NHS. There a...
