Hi everyone,

Thanks to all for the excellent discussion on this list. 

With respect to Sandra, I don't think the definition of high quality research evidence should be different in non-medical professions.  I think that in all professions we need to use the most appropriate study design to the question at hand. If we are testing the effects of interventions we really do need an RCT to be sure that effects seen really are as a result of the intervention given (or even better a high quality systematic review). If we have a question about prognosis and factors which influence outcome we need a cohort study. If we are seeking to understand patients' experiences we need qualitative studies. Physiotherapists have written about this approach in the book "Practical Evidence-based Physiotherapy", Herbert et al 2005 http://www.elsevier.com/wps/find/bookdescription.cws_home/705265/description#description
 
Within physiotherapy we have created PEDro http://www.pedro.org.au/ which aims to cut down searching and appraisal time by giving access bibliographic details of quality-rated trials, reviews and evidence-based guidelines of relevance to physiotherapy (we now have 15,000 records!). Similar resources are now available for occupational therapists http://www.otseeker.com/ , speech pathologists http://www.speechbite.com/ and psychologists working with people with brain injury http://www.psycbite.com/  

Of course these databases do not solve all the challenges others have identified in the real world daily application of evidence. Clinicians still need to interpret the results of research studies and use these to assist in decision making in conjunction with individual patients. 

I am awaiting the updated Sicily statement with interest. 

Best wishes,
Cathie

Subject: Re: The EBM curriculum - revising the Sicily statement

Hi all, Thank you for this running discussion.  As a non-physician, I  
would like to remind all that other disciplines have adopted the  
approach of EBM, but have broadened it conceptually to be evidence  
based practice. That said, I agree with point 3, but often that is  
interpreted to mean that RCTs have it over cohort studies. In the area  
of ongoing therapies, such as physical, occupational, speech, or  
behavioral health, RCTs may not always reflect  the best evidence for  
the real clinical world, where patient mix is messy, and many  
confounding variables are known to affect therapy outcomes. If a list  
of principles are to be developed, it should be inclusive of the ways  
EBP is used by all health professions.  In fact, it does not sound as  
though we need a list of principles as much as a decision tree process  
or flow chart that accounts for all of the steps and inputs to the  
clinical decision making process.  And quite possibly, those flow  
charts may look different for different stages of care, and for  
different types of health services (emergency vs acute vs chronic  
management). In all cases, the starting point will be the patient's  
problem that generates the question, and the end point will be  
assessment of the impact on the patient for achieving the desired  
outcome.
I am really looking forward to a real time discussion of these ideas  
next week.
