Title: CAGS Evidence Based Reviews in Surgery EBRS
1Evidence Based Reviews in Surgery A Joint
Program of The Canadian Association of General
Surgeons Lassociation Canadienne des Chirurgiens
Généraux and the American College of Surgery
2Evidence Based Medicine
The conscientious and judicious use of the best
current evidence from clinical care research in
the management of individual patients Sackett
et al
3Components of Evidence Based Medicine
- Produce the best evidence
- Disseminate and access the best evidence
- Critically appraise the best evidence
- Apply the best evidence to individual patients
- Audit ones own results
4Critical Appraisal Skills
- Skills that enable one to apply certain rules of
evidence and the laws of logic to clinical
investigative and published data in order to
estimate their validity, reliability, credibility
and utility - Requires some knowledge of research design,
statistics, economic analysis, decision analysis
and clinical knowledge
5Issues
- Treatment effectiveness
- Natural history (prognosis)
- Causation / risk
- Measurement
- Diagnostic tests
- Early diagnosis / screening
- Practice guidelines, decision analysis, economic
analysis, meta-analysis, outcomes studies
6Evidence Based Reviews in Surgery
- Internet based journal club designed to teach
critical appraisal skills to practicing general
surgeons and residents - EBRS initiated by the Canadian Association of
General Surgeons in 1999 - Interest in Canada in EBRS because
- critical appraisal skills must be taught as part
of the residency curriculum - RCPSC instituted the Maintenance of Certification
Program
7Evidence Based Reviews in Surgery
- 8 packages per year
- Each package consists of the following
- clinical article
- methodological article
- clinical scenario
- questions stimulating evaluation of the
methodology - clinical and methodological critiques
- All articles and reviews available
electronically

9Please read the above articles and be prepared to
discuss the following 1. What is the clinical
question being addressed? 2. Was the assignment
of patients to treatment randomized and
concealed? 3. Were all patients who entered the
trial properly accounted for? 4. Were patients,
their clinicians and study personnel blind to
treatment? 5. Were the groups similar at the
start of the trial? 6. Aside from the
experimental intervention, were the groups
treated equally? 7. How large and precise was
the treatment effect? 8. Were the study patients
similar to my patients? 9. Were the measured
outcomes clinically relevant? 10. Were all
clinically important outcomes considered? 11. Are
my surgical skills similar to those of the study
surgeons? 12. State the conclusion. Have the
authors addressed the question? 13. Does the
evidence support the conclusion?

10Clinical Scenario
A well informed 52 year old male presents with a
T2 rectal cancer. He questions the need for
radiotherapy because he has been on the internet
and learned that functional results are worse
following radiotherapy. What is your advice?

12Other Topics Covered in Past Years
- Decision analysis on bariatric surgery vs. diet
- FAST as a diagnostic tool in the trauma setting
- Management of CBD stones
- Practice Guidelines for gastric cancer, DCIS,
splenic trauma in children - Diagnostic tests MRCP, CT angiography,
colonography - Management of inguinal and ventral hernias
13Status of EBRS
- RCT which was designed to test whether this
method of teaching critical appraisal skills to
practicing general surgeons is effective - 82 CAGS members participated
- Participants randomized to
- received clinical article only
- received EBRS packages (1 year)
- Outcome validated test assessing critical
appraisal skills - 70/82 surgeons completed the study
- Surgeons in the intervention group did
significantly better than those in the control
group on a valid critical appraisal test
14Status of EBRS
- Since 1999, EBRS has been made available to all
general surgery training programs in Canada - 13 of the 16 general surgery programs in Canada
use it consistently for teaching critical
appraisal skills as part of their Journal Club
15Current status of EBRS
- CAGS and the ACS signed an agreement in 2004 so
EBRS is a joint project - EBRS is now available to members of the ACS via
the ACS website - facs.org

16Current status of EBRS
- Steering committee includes Canadian and American
surgeons - representatives from the Canadian Program
Directors and APDS - resident representatives from Canadian and
American general surgery programs - The administrative center is in Toronto
- administrative assistant is Marg McKenzie
17Current Status of EBRS
- Methodological reviews are completed by the
Steering Committee members - Clinical reviews are completed by Canadian and
American experts - Separate listserves with experts
- Main Cert and CME Credits are available to
participants
18Current Status of EBRS
- EBRS has a library of approximately 50 past
articles and reviews which may be accessed at any
time using an index based on clinical and
methodological topics - Subscriptions to approximately 10 medical and
surgical journals are maintained and may be
accessed for personal use by members - Reviews are published in the Canadian Journal of
Surgery and Journal of the American College of
Surgery (4 in each journal each year) - To date, 18 articles have been published
