The readiness of oncologists to disclose information to patients with advanced and incurable cancer
Nathan I Cherny
Communication and oncologists
central task challenging source of substantial professional stress
Patients
Distressedimpact of a life-threatening illnesscomplex treatment decisions often limited likelihood of major benefitbalancing hope + realism
Respect for Persons
ethical axiomPersons generally know what is best for
themselves information participation
Disclosure
Disclosure, in this context, refers to the imparting of information necessary to make informed decisions about ongoing care.
The key elements of information necessary for patients to make informed decisions include
the diagnosisthe extent of diseasethe range of therapeutic options availablethe likelihood of benefit from each of the
treatment optionsthe anticipated scope of benefitthe likelihood of adverse effects or harmpotential severity of such adverse effects.
Patient data
Patients vary in the degree to which they want to be medically informed
Western countries: overwhelming majority
non-Western countries: substantial proportion
Not individually predictable by geography, Culture Age Race sex educational level
Family opinions
Multiple studies family members commonly underestimate
the amount of information that patients desire the degree to which they want to be involved in
decision-making
Consnsus
Ethical, medical, psychological, legal (and anthropological
physicians should ask patients about their individual preferences regarding disclosure of information and then act in accordance with the patient's opinion unless there are compelling contraindications.
Reasons for less than full disclosure
Harm
Profiling culturally Age education
requests by family members
professional role expectations
lack of time
personal difficulty in dealing with "bad news" dialogues
Previous Studies of Oncologists
vary substantially in the disclosure practices degree of disclosure with any one patient is highly
influenced by individual factors
Western oncologists more disclosive than those practicing in non-Western countries
other factors sex age training in the communication of bad news frequent requests from family members for nondisclosure
Patient derived data
Even in Western countries patient-derived data indicates disclosure is often less than complete less than patients want
Adverse Consequences of poor communication with lack of disclosure
psychological distress to the patient and their family
unnecessary treatment or overly aggressive treatment costs to the health care system harm to patients
indirect system distress Burnout Stress Conflicts within the health care team
ESMO Survey
To study European Oncologists' attitudes towards information disclosure to
patients with advanced cancerself-reported behaviors in this clinical settingthe factors that influence both attitudes and
behaviors.
Study parameters Demographics
Oncologists attitudes regarding disclosure and information transfer
Self Reported oncologist behaviors in dealing with issues of disclosure request to collude against the patient hard case decision making regarding limited therapeutic options and dwindling
therapeutic options
Local Norms To evaluate the pressures exerted on oncologists to withhold information from
patients or family members
Subjective adequacy training in difficult dialogues
Predictors of Attitude, Behavior The impact of education, attitudes, family and peer expectations, geography and
other demographics on how clinicians approach these complex tasks.
Questions
To what degree does culture effect attitudes and behaviors regarding information disclosure to patients with advanced cancer?
What factors modify this effect?DemographicRigid factorsFactors amenable to intervention
Methodology
Survey tool
focus group of oncologists participating in the Palliative Care Working Group of ESM a survey tool was drafted.
Peer review process for face validity
The final version of the survey Demographics (items 1-7), Requests for collusion (patient and family norms) (item 9) Clinical scenarios (items 8, 10-12), Single items relating to:
information aids (13)enquiries abut emotional issues (14)second opinions (15)divergent opinions (16)
27 attitudes (item 17) 2 Education (1tem 17 embedded) 2 Opinion (17 embedded).

Survey administration
All members of ESMO were invited to participate (4000 aprox)
The survey was offered online
reminder letters from the ESMO president every 2 weeks over a 2 month period in 2006.

Major findings
Individual clinicians generally display range of responses including disclosive and non disclosive behaviors
Culture is an important determinant of default behaviors but its impact is tempered by other important factors
1. Local professional norms (may be independent of culture)
2. Training in disclosure communication3. Experience4. Age (youth)
In non Western countries about 25-30% of clinicians are extremely non disclosive

Summary
The Data from the survey help clarify the relationship between culture and non-disclosive and paternalistic practices.
The influence of culture is mediated through other factors.
Consistent with anthropological and social psychology data
Supports thesis of cultural relativism rather than ethical relativism
