Evidence-based Practice The way forward

‘Physiotherapy practice makes direct reference to published research evidence, as well asindicators of effective intervention in the form of clinical standards and clinical guidelines.Practice is informed by physiotherapy-specific research as well as the general scientificliterature, and in this way engages in evidence-based practice’ (QAA, 2003).
IntroductionThe statement quoted above from the HealthProfessions Council draft standards of proficiencyclearly enshrines the imperative for evidence-basedpractice as a central activity, supporting the premisethat physiotherapists have both a professional andethical obligation to provide an evidence-basedservice (Bithell, 2000). However, the success withwhich this is achieved is the subject of debate (Turner,2001).
Many negative attitudinal and practical issues havebeen identified in the literature which act as obstaclesto fulfilling the requirements of evidence-basedpractice in physiotherapy. These not only challengethe quality of service provided, but have createdtensions among different occupational groups withinthe profession which a coherent and consistentapproach to evidence-based practice would avoid. Forexample, educators are faced with dilemmas on whatto teach students when the evidence does not supportcontinued use of certain treatment modalities, butthese are still used in practice (Turner and Whitfield,1999).
Although evidence-based practice is a complexconcept with challenges to implementation, theseshould not be viewed as deterrents to engaging inevidence-based practice in physiotherapy. However,further development is needed to manage thevariability in the quality of evidence as an encour-agement to change.
Improvements in access to electronic and printedforms of high quality reviews of available researchevidence have shown that often insufficient or in-adequate research has been published (Moseley et al,2002). Available research evidence should be takeninto account in decision-making, but the quality ofthat evidence should have a bearing on thosedecisions.
The continuing use of treatment modalities whichresearch evidence has demonstrated to be eitherineffective or unjustifiable due to lack of scientificsupport is cause for concern (Baker et al, 2002;Robertson et al, 2002). This practice is potentially
harmful to patients and may form the subject oflitigation in the future.
Attendance at short courses continues to be apopular form of continuing professional develop-ment, but many of these continue to be presentedwithout reference to or support of evidence (Turnerand Whitfield, 1999). Physiotherapists need to bediscerning about which courses they choose to attend,an approach which should lead to improvements inthe quality of courses offered.
StrategiesMany of the identified obstacles to evidence-basedpractice may be overcome by a positive attitudeamong managers and staff in both clinical practiceand education, and efficient, effective use of availabletime and resources. Time allocated to in-servicetraining in clinical departments could be used todisseminate and discuss research evidence andclinical guidelines rather than to communicateexperiential or anecdotal learning not linked toresearch evidence. This approach has been suc-cessfully adopted by some departments.
In addition to efficient use of time and the need fora positive departmental culture, it is important thatpractitioners have the resources needed to accessevidence. Computer facilities in the workplace areimproving as part of government funding for theNational Health Service. Many clinicians already haveaccess to libraries, computers and the Internet. Thismeans that the sources needed to inform practice arebecoming increasingly available.
The success of the system relies upon disseminationof high quality, relevant research. Researchers havean obligation to facilitate this process by undertakingresearch which has relevance to clinical practice,preferably with collaboration between researchersand clinicians (Culham, 1998). Researchers also havea responsibility to present their findings in a user-friendly manner, facilitated by the discipline ofacademic style (Bithell, 2000).
The findings of the survey by Turner and Whitfield(1999) suggested that selection of treatment tech-

niques is based primarily on what practitioners had been taught during their qualifying education.Undergraduate education should be considered asonly the start of professional learning. It is continuingprofessional development, with an inbuilt focus onevidence-based practice, which should inform theprofession and ensure professional growth.
Physiotherapy educators have an obligation to useevidence to support the academic knowledge andpractical skills they teach and inculcate an ethos ofevidence-based practice in students which transfersinto the clinical setting (Turner and Whitfield, 1999).Achievement of this goal is facilitated if a uniformapproach to the evidence is adopted by bothclinicians and educators. Research has found thatstudents follow the example set by their clinicaleducators above that of academic staff (Turner andWhitfield, 1999), highlighting the importance of anethos of establishing an evidence base in the clinicalenvironment.
Universal NeedIn summary, the requirement for evidence-basedpractice applies to the whole physiotherapy prof-ession and involves managers, researchers, educ-ators and students as well as clinicians. Althoughundertaking evidence-based practice is complex,none of the perceived obstacles is insurmountableand many solutions already exist. The physiotherapyprofession now needs to move forward from debate,adopt a universally positive attitude and be seen to beimplementing evidence-based practice in a coherentmanner across the profession.
