Communication and oncologists

central task challenging source of substantial professional stress

Page 3: Nathan I Cherny

Patients

Distressedimpact of a life-threatening illnesscomplex treatment decisions often limited likelihood of major benefitbalancing hope + realism

Page 4: Nathan I Cherny

Respect for Persons

ethical axiomPersons generally know what is best for

themselves information participation

Page 5: Nathan I Cherny

Disclosure

Disclosure, in this context, refers to the imparting of information necessary to make informed decisions about ongoing care.

Page 6: Nathan I Cherny

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.

Page 7: Nathan I Cherny

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

Page 8: Nathan I Cherny

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

Page 9: Nathan I Cherny

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.

Page 10: Nathan I Cherny

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

Page 11: Nathan I Cherny

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

Page 12: Nathan I Cherny

Patient derived data

Even in Western countries patient-derived data indicates disclosure is often less than complete less than patients want

Page 13: Nathan I Cherny

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

Page 14: Nathan I Cherny

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.

Page 15: Nathan I Cherny

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.

Page 16: Nathan I Cherny

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)

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

Page 58: Nathan I Cherny

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
