Salbach et al (2011) buy GSI-IX identified online access to research summaries and systematic reviews as a potentially important facilitator because this can save time to search and critically evaluate research articles. Studies on barriers and facilitators for EBP are potentially useful for designing and implementing interventions to change these factors and increase

the extent to which EBP is implemented. However, this research has certain challenges and limitations. Surveys of EBP barriers and facilitators have assessed the individual importance of a number of factors. However, there might be synergistic effects such that two seemingly minor barriers constitute an important obstacle to EBP if they interact. It is learn more also plausible that changes in specific barriers affect other barriers, suggesting that there are no simple cause-and-effect relationships between individual factors and the extent to which EBP is implemented. Rather, it is reasonable to assume that many factors are associated and interrelated in various ways that are not always

predictable (or measurable by means of surveys). Studying various barriers and facilitators to EBP in isolation makes research more manageable, but it may hinder in-depth understanding of how evidence-based physiotherapy can be increased. Another issue is whether all relevant barriers are examined in the barrier studies. Most studies have used quantitative designs, being based on survey questionnaires. These questionnaires usually consist of a number of barriers (such as ‘the research is not reported clearly and readably’ and ‘the amount of research information is overwhelming’) which the respondents are requested to rank on a Likert scale (eg, Iles and Davidson 2006, Grimmer-Somers et al 2007) or in terms

of selecting ‘your 3 greatest barriers to the use of EBP in your clinical practice’ (eg, Jette these et al 2003). The studies also incorporate questions regarding attitudes to EBP (eg, ‘EBP is an essential component of physiotherapy practice’), skills/self-efficacy in practising EBP (eg, ‘I do not feel capable of evaluating the quality of the research’) and knowledge of EBP-related terms. Although these studies have covered many aspects of EBP, they probably do not encompass all potentially inhibiting factors. Surveying the perceived importance of a finite set of pre-determined barriers can yield insights into the relative importance of these particular barriers, but may fail to identify factors that independently affect EBP outcomes. Further, there is the issue of whether the barriers that have been identified by physiotherapists are the actual barriers.
