Session 3. Part II

What is a profession?
A monopoly
How do we get this privilege?

What is a profession?
Expertise –
Code of ethics
What do we get in return?
Autonomy

Challenge of the profession/al
Challenge of maintaining expertise
Staying up-to-date in your field

Types of information directed at clinicians
1) Info that describes available treatments
without providing a basis for choosing among them
2) Info that describes biomedical/dental research results
 without exploring their clinical implications

Types of information directed at clinicians
3) Info designed to deliver practice-relevant    information
Effectiveness and outcomes research
Information concerning which practices lead to better outcomes

Effectiveness and outcomes research
Goal is to improve the quality of health care provided to patients
Especially health outcomes
How to reach the clinician and make this happen?

Effectiveness and outcomes research
Dissemination issues
Need to reach practitioners
Crucial role in determining whether goal is realized
Behavior change issues
 effectiveness/outcomes research will not have an impact if…
It does not convince practitioners to comply

Dissemination of information
Process of communicating information
Sources
Biomedical/dental research
NIH panels
Professional associations

Dissemination of information
Transmitted through various media
Journals
Conferences
Word of mouth
Popular press

Dissemination of information
Reaches various audiences
Policymakers
Health care providers
Payers
Consumers

Does dissemination of information change behavior?
It is assumed
 that when providers encounter new information
suggesting they should change the way they treat their patients
That they are willing to change

Does dissemination of information change behavior?
Quality of care likely to be achieved
Only if relevant research findings and guideline recommendations
appropriately incorporated into practice

How does profession influence behavior? 
Modes of professional influence
1) Regulatory influence
(Threat of punishment/prospect of reward)
Present-day manifestations of regulatory (or direct) influence can be found in:
Third-party reimbursement policies
Threat of malpractice
Sanctions by peer review or other
authoritative bodies

Modes of professional influence
2) Normative influence
Impressions of what the profession expects you to do
What your colleagues expect you to do
What the “experts” expect you to do
What your patients expect you to do
What the professional leadership expects you to do

Modes of professional influence
3) Informational influence
Factual influence
Providing information that leads to belief that should change your practice


Informational influence
Informational influence – mode of influence that characterizes dissemination efforts
Randomized clinical trials
Consensus recommendations
Clinical practice guidelines
Continuing education courses

1) Randomized clinical trials
Results of randomized clinical trails reported by scientific investigators
Seek to document their methods and results for the scientific community
May have no specific intent to shape practitioner’s behavior

Systematic reviews in dentistry
Bader, JD, Shugars DA, Bonito AJ.  A systematic review of the performance of methods for identifying carious lesions.  Journal of Public Health Dentistry, 62: 201-213, 2002.
Bader, JD, Shugars DA, Bonito AJ.  A systematic review of selected caries prevention and management methods.  Community Dent Oral Epidemiol 29: 399-411, 2001.
Bader, JD, Shugars, DA, Bonito AJ.  Systematic reviews of selected dental caries diagnostic and management methods, J Dent Ed 65: 960-968, 2001.

Use of the “systematic review” as alternative in dentistry
1)  Identify questions to be answered
2)  Define study inclusion/exclusion criteria
3)  Conduct literature search
4) Abstract the articles
5) Evaluate the evidence

RCT’s – influence clinician’s behavior?
Fineberg reviewed many studies of effects of clinical evaluations on physicians’ behaviors
Despite difficulty in discerning long-term effects of RCTs
clear that physicians do not respond rapidly or in large numbers to newly published findings of RCTs
In many cases, little or no change in practice even after a considerable amount of time

2) NIH consensus conferences
One of the most visible activities aimed at disseminating information on state-of-the-art therapy
National Institutes of Health (NIH) Consensus Development Program
conducts evaluations of biomedical/dental technologies
produces and disseminates consensus statements
aimed at health care providers, the public, and the scientific community

NIH consensus conferences
http://consensus.nih.gov
Consensus statements prepared by a nonadvocate, non-Federal panel of experts based on:
1) presentations by investigators working in areas relevant to question
2) presentations made during 2-day public session

NIH consensus conferences
3) questions and statements from conference attendees during open discussion periods are part of the public session
4) closed deliberations by the panel during the remainder of the second day and morning of the third

NIH consensus conferences
5) statement is an independent report of the panel and not a policy statement of the NIH or the Federal Government
6)  statement reflects the panel’s assessment of knowledge at the time written
Provides a “snapshot in time” of the state of knowledge
When reading the statement, keep in mind that new knowledge is inevitably accumulating through research

NIH Consensus Conferences pertaining to dentistry
Dental implants: benefit and risk – June 1978
Removal of third molars – Nov 1979
Dental sealants in the prevention of tooth decay – Dec 1983
Dental implants – June 1988
Oral complications of cancer therapies: diagnosis, prevention, and treatment – April 1989
Diagnosis and management of dental caries throughout life – March 2001

NIH consensus conferences
Study evaluating the NIH Consensus Development program – Rand Corporation – David Kanouse
Used medical record review (behavior) to examine changes in hospital-based procedures that were subject of conference
Physician’s self-reported preferred practices were strongly related to what actually did
Although program’s dissemination effort was moderately successful at reaching the appropriate target audience
the conferences mostly failed to stimulate changes in physicians’ practices.

Clinical practice guidelines (CPG)
Systematically developed statements
 to assist practitioner and patient decisions
about appropriate health care for specific clinical circumstances”
Their successful implementation should improve quality of care
 by decreasing inappropriate variation
 and expediting the application of effective advances to everyday practice

Clinical practice guidelines (CPG)
Despite wide dissemination
guidelines have had limited effect on changing clinician behavior
Little is known about the process and factors
 responsible for how clinicians change their practice standards
 when they become aware of a guideline

Barriers to CPG adherence
Adherence to guidelines may be hindered by a variety of barriers
A theoretical approach can help explain these barriers
possibly help target interventions to specific barriers

Barriers to CPG adherence
Cabana et al., Why don’t physicians follow clinical practice guidelines, JAMA 282 (15), October 20, 1999, 1458-1465.
Barrier defined as “any factor that limits or restricts complete physician adherence to a guideline”
Focus on those that could be changed
As a result did not consider age, sex, ethnic background, or specialty of the clinician

Knowledge-related barriers
Lack of awareness
The inability to correctly acknowledge a guideline’s existence
Lack of familiarity
Included the inability to correctly answer questions about a guidelines content as well as self-reported lack of familiarity

Attitudinal barriers
Lack of agreement
Differences in interpretation of the evidence
Belief that benefits not worth patient risk, discomfort, or cost
Applicability to the practice population
Guidelines oversimplified or “cookbook”
Guidelines reduce autonomy
Authors’  lack of credibility , bias

Attitudinal barriers
Lack of self-efficacy
Belief that s/he cannot perform guideline recommendation
Lack of outcome expectancy
Belief that performance of guideline recs will not lead to desired outcome

Attitudinal barriers
Lack of motivation/
Inertia of previous practice
Habit
routine

External barriers
Patient factors
Inability to reconcile patient preference with guideline recs
Guidelines
Guideline characteristics
Difficult to use
Not convenient
Cumbersome
Confusing
Presence of contradictory guidelines

External barriers
Environment
Lack of time
Lack of resources – insufficient staff or consultant support
Lack of reimbursement
Perceived increase in malpractice liability
