Evaluation & Future plans
The evidence base
Opportunities for librarians
A series of six workshops introducing research
methods and tools to help appraise:
Clinical Trials, Systematic Reviews, Qualitative studies, (CASP)
Guidelines (AGREE), Patient information (DISCERN)
Research methods and introduction to CASP
One : One
Research methods and levels of evidence
For qualitative studies?
No consensus about the relative rigour of different methods
Levels of evidence
Case series and case reports
For quantitative studies
Judging the quality of research
Checklists e.g. CASP
A framework for thinking about the quality of research
NHS Critical Appraisal Skills Programme
Is the methodology appropriate to answer the question.
Is it carried out in a sound way, eliminating bias and confounding?
Are the results real or because of chance?
Introducing / revisiting probability or p-values and confidence
intervals. Interpretation of odds ratio diagrams
Will the results help locally?
Personal research & interest
leading to pre-2002 sessions (RCTs & Systematic reviews)
CASPfest & CASP workshops
e.g. Training the Trainer
Sheffield Evidence Appraisals From ShEBaNg (ShEAFS)
CASP training week
MSC Health Services Research
Who has participated?
Approximately 100 staff since 2002, representing a
range of clinical specialties, health professions and
Overview sessions presented to:
Neonatal postgraduate teaching programme
O&G research and evidence programme
Medical house officer teaching programme
Neonatal Unit multidisciplinary Journal Club
Staff in genetics, family planning, surgery, renal nursing
and mental health pharmacy
Evaluation following sessions
has been very positive
“Excellent and interesting, even for a beginner like myself”
“A very helpful ‘revisiting’”
“Came away learning lots”
“Now understand confidence intervals”
“Made trials understandable”
Supporting workplace research, education and
Generated ideas for qualitative research proposal
Supported staff doing research modules
evaluating RCTs e.g. of escitalopram vs citalopram for major
depression – mental health pharmamcist
LEicestershire Appraisal Forum (LEAF)
Regular group to evaluate locally relevant
research and develop appraisal skills
LEicestershire Appraisal Forum Locally
Appraised Topics (LEAFLETs)
Appraisal summaries on the Intranet as an
educational / EBM tool.
Recent questionnaire to workshop attendees
2002-2004: Response rate 15% (12/82)
Overall very positive views of sessions
A majority have used CASP or similar checklists since
Most report being ‘fairly confident’ in appraisal skills
A majority would make time to attend the proposed
LEAF and could see value in LEAFLETs. Of those
who couldn’t attend, barriers were time & geography.
Basis to take the LEAF forward
The evidence base
Systematic review of critical appraisal teaching
Parkes et al. 2001. A cautious
“Critical appraisal teaching has a positive affect on
participants’ knowledge” Generalisable?
“Highlighted the poor evidence in this area but it is not
evidence for stopping critical appraisal teaching”
Skills, attitudes and behaviour?
The holy grail: impact on patient care
Opportunities for librarians 1
Work in partnership with clinical staff - sharing
knowledge and skills
CASP checklists are new to most
Don’t assume participants have high levels of
knowledge. Be adaptable
Have a good stats dictionary handy
Put statistics in their place
Opportunities for librarians 2
Individual email effective but no longer possible
Posters / flyers
Word of mouth
Structured postgraduate teaching
Opportunities for librarians 3
Demand for support in other related areas e.g.
Endnote / Reference Manager
Care needed not to overstretch ourselves
But librarians need to develop their roles, not
least because of national developments e.g.
NLH, NCC, e-journals & document delivery
