This study examined responses of 21 lung cancer outpatients to questions ab
out their desired and actual levels of involvement in treatment decisions,
and about information needed for treatment decision-making. A 'treatment tr
ade-off interview was used to assess patients' preferences for hypothetical
treatment options. Desired roles in decisions are examined in relation to
treatment preference and information needs. Forty-three percent of patients
recalled desiring an active/collaborative role in their real treatment dec
ision. For 29% of patients, there was a discrepancy between their recalled
desired role and their recalled actual role; in each of these cases the pat
ient had been less involved in the decision than they had desired. At the t
ime of the interview (mean 26 months post-treatment), 57% of patients desir
ed an active or collaborative role in treatment decisions. The majority of
patients rated the following types of information as 'essential' to treatme
nt decisions: details of the treatment regimen, early and late side-effects
, survival, and effects of treatment on disease symptoms. The data suggest
that: we should be attentive to the individual's desired role in treatment
decisions at each step of care to avoid a mismatch between desired and actu
al involvement; desired role in decision-making does not predict treatment
preference; and patients generally want a wide variety of information on tr
eatment options in order to participate in treatment decisions. Copyright (
