This study examined responses of 21 lung cancer outpatients to questions about their desired and actual levels of involvement in treatment decisions, and about information needed for treatment decision-making. A 'treatment trade-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. ⋯ At the time of the interview (mean 26 months post-treatment), 57% of patients desired an active or collaborative role in treatment decisions. The majority of patients rated the following types of information as 'essential' to treatment 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 actual involvement; desired role in decision-making does not predict treatment preference; and patients generally want a wide variety of information on treatment options in order to participate in treatment decisions.

The psychological outcome of family carers after bereavement is an important issue in evaluating palliative care services. Palliative care services have the potential to provide preventive psychosocial intervention to family carers prior to bereavement, but are faced with the need to identify those who may have greatest risk of adverse outcome. This prospective study examines predictors of psychological outcome for family carers of cancer patients following bereavement based on factors identified at referral to a palliative care agency. ⋯ The findings indicate clinical risk factors for adverse short-term bereavement outcome that can be identified in family carers during palliative care treatment, that have implications for identifying the psychological needs of carers, and that form a potential basis for interventions to enhance the psychological outcome for family carers.

A brief spiritual beliefs inventory for use in quality of life research in life-threatening illness.
This paper reports on the initial efforts to validate a brief self-report inventory, the Systems of Belief Inventory(SBI-15R), for use in quality of life (QOL) and psychosocial research studying adjustment to illness. The SBI-15R was designed to measure religious and spiritual beliefs and practices, and the social support derived from a community sharing those beliefs. The authors proposed this scale to address the need for greater exploration of spiritual and religious beliefs in QOL, stress and coping research. ⋯ DISCUSSION. The SBI-15R met tests of internal consistency, test-retest reliability, and convergent, divergent, and discriminant validity in both physically healthy and physically ill individuals. The SBI-15R may have value in measuring religious and spiritual beliefs as a potentially mediating variable in coping with life-threatening illness, and in the measurement of QOL.

The 'WHO Analgesic Ladder' is a well validated approach for the selection of appropriate analgesic therapy for cancer pain as well as pain in AIDS. The mainstay of analgesic intervention for cancer and AIDS pain of moderate to severe intensity continues to be the appropriate use of opioid analgesics. There is, however, a growing appreciation for the role of adjuvant analgesics, such as antidepressants and other psychotropic medications, at each step of the WHO Analgesic Ladder, particularly in the treatment of neuropathic pain. ⋯ This paper reviews the literature on the use of antidepressants, psychostimulants, neuroleptics, anticonvulsants and other psychotropic analgesics in the management of cancer and AIDS pain. Mechanisms of analgesia, drug selection, and recommendations for clinical usage are discussed. The appropriate and timely use of psychotropic adjuvant analgesic drugs represents an opportunity for active psychiatric contribution to the multidisciplinary management of cancer and AIDS pain.

An overview of drug metabolism, with particular focus on the cytochrome p450 system, is provided in this review. To date, there has been a growing body of literature concerning the cytochrome p450 enzyme, drug-drug interactions and the role of psychotropic medications when co-administered with medications prescribed in the medically ill population. ⋯ This information will permit the clinician working in an oncologic setting to better predict potential interactions based on available in vitro and in vivo data and choose psychotropics analytically when confronted with a situation of polypharmacy. A knowledge of drug interactions will decrease the uncertainty in prescription of multidrug therapies and minimize the likelihood of diminished drug efficacy or toxic reactions.
