Associations of race with depression and symptoms in patients on maintenance haemodialysis.

BACKGROUND: Although studies have shown that African American haemodialysis patients report better overall quality of life than Whites, racial differences in depression and symptom burden remain less well characterized. The aim of this study was to compare these domains between African American and White patients on chronic haemodialysis. METHODS: We surveyed African American and White maintenance haemodialysis patients. Depression was assessed using the Beck Depression Inventory (BDI) and Cognitive Depression Index (CDI). Symptoms were evaluated using the Dialysis Symptom Index (DSI). RESULTS: Among the 82 Whites and 78 African Americans enrolled, there were no racial differences in the prevalence of depression (27% in African Americans vs 27% in Whites, P = 1.0), BDI Scores (11.2 vs 10.9, P = 0.6) or CDI scores (6.0 vs 6.0, P = 0.9). Symptom burden was substantial in both African Americans and Whites (median number of symptoms 8.5 and 9.0, respectively) with no racial differences in the overall burden or severity of symptoms. However, based on a single item, African Americans were more likely to describe their religious/spiritual beliefs as "very important". Adjustment for demographic and treatment characteristics had no impact on the associations of race with depression or symptoms. CONCLUSIONS: Depression and symptoms are highly prevalent in both African American and White haemodialysis patients, without racial differences in these health-related domains. In exploratory analyses, spiritual/religious beliefs appear to be of greater importance to African Americans. The relevance of these observations to the advantages in quality of life and survival among African Americans on haemodialysis warrants further investigation.

Pushing up daisies: implicit and explicit language in oncologist-patient communication about death.

GOALS OF WORK: Although there are guidelines regarding how conversations with patients about prognosis in life-limiting illness should occur, there are little data about what doctors actually say. This study was designed to qualitatively analyze the language that oncologists and cancer patients use when talking about death. SUBJECTS AND METHODS: We recruited 29 adults who had incurable forms of cancer, were scheduled for a first-time visit with one of six oncologists affiliated with a teaching hospital in Australia, and consented to having their visit audiotaped and transcribed. Using content analytic techniques, we coded various features of language usage. MAIN RESULTS: Of the 29 visits, 23 (79.3%) included prognostic utterances about treatment-related and disease-related outcomes. In 12 (52.2%) of these 23 visits, explicit language about death ("terminal," variations of "death") was used. It was most commonly used by the oncologist after the physical examination, but it was sometimes used by patients or their kin, usually before the examination and involving emotional questioning about the patient's future. In all 23 (100%) visits, implicit language (euphemistic or indirect talk) was used in discussing death and focused on an anticipated life span (mentioned in 87.0% of visits), estimated time frame (69.6%), or projected survival (47.8%). CONCLUSIONS: Instead of using the word "death," most participants used some alternative phrase, including implicit language. Although oncologists are more likely than patients and their kin to use explicit language in discussing death, the oncologists tend to couple it with implicit language, possibly to mitigate the message effects.

Mental and physical symptoms associated with lower social support for patients with hepatitis C.

AIM: To systematically examine the impact of the hepatitis C virus (HCV) diagnosis on patients' level of social support in a large-scale study. METHODS: Patients evaluated and treated for HCV in a tertiary referral center were enrolled in a cross-sectional study. Demographic data, functional and emotional status as measured by the Hospital Anxiety and Depression Scale (HAD) and the Sickness Impact Profile (SIP), severity of liver disease, mode of acquisition, and physical and psychiatric comorbidities were collected from patients or abstracted from the medical record. All participants completed a semi-structured interview, addressing questions of social support. RESULTS: A total of 342 patients (mean age 45.2 years; 37% women) were enrolled. Ninety-two (27%) patients described lower levels of support by family and friends. Nearly half of the participants (45%) noted the loss of at least one relationship due to the disease. Fears related to transmitting the disease (25%) were common and often associated with ignorance or even discrimination by others (19%). Nearly one fifth of the patients did not share information about their disease with others to avoid being stigmatized. Lower levels of social support were significantly associated with living alone, being unemployed, being excluded from antiviral therapy, having psychiatric comorbidities, contracting HCV through intravenous drug use, having high levels of anxiety and depression as measured by the HAD and negative mood state as measured by the SIP. Patients reporting lower levels of social support also noted more physical symptoms as measured by the SIP. CONCLUSION: Patients with hepatitis C often face significant social problems, ranging from social isolation to familial stress. The most common concerns reflect a limited insight of patients and their relatives and friends about the disease, the risk factors for its spread, and about potential consequences. Our data suggest that educational interventions targeting support persons and the stressors identified in our findings may lessen or alleviate the social strains patients with hepatitis C experience.

Opioid contracts in chronic nonmalignant pain management: objectives and uncertainties.

In this article, we review the principal objectives and ideal elements of opioid contracts, as articulated by proponents of the practice. We examine the limited empirical evidence for the effectiveness of opioid contracts in achieving their intended objectives and identify areas of uncertainty and of ethical concern regarding their implementation. We argue that the challenge in deciding about implementing opioid contracts in clinical practice relates to the multiplicity of potential objectives they might serve, to a lack of empirical evidence regarding their effectiveness, and to ethical concerns over their implementation. Specialty and primary care clinicians contemplating the use of opioid contracts in treating patients with chronic nonmalignant pain need to be sensitive to these considerations, and further debate and research is necessary to establish the proper objectives, elements, effectiveness, and ethical justifications of opioid contracts in clinical practice.

Congestive heart failure patients report conflict with their physicians.

BACKGROUND: Given the importance of the doctor-patient relationship, we examined the prevalence and nature of patients' perceived conflicts with the physicians caring for their congestive heart failure (CHF). METHODS AND RESULTS: This cross-sectional study recruited patients with CHF in the outpatient and inpatient service of a tertiary referral hospital. Patients completed demographics, semistructured interviews, and surveys of emotional and health status. CHF physiologic measures and comorbidities were abstracted from the medical record. A team of 2 blinded coders analyzed the interviews. Thirty-one percent of the 289 patients reported difficulties with physicians. In the bivariate analysis, only marital status was significantly associated with conflict. Major problems included the providers' poor communication skills (20%), trust in the physicians' competence (18%), and insufficient medical information (16%). Patients identified care outside the tertiary referral hospital (13%) and inadequate communication between physicians (9%) as additional sources of difficulty. CONCLUSION: Perceived conflict with providers is common in patients with CHF. Patient-level factors, however, did not predict conflict, which differs from our previous findings with hepatitis C patients. Perceived conflict is troubling because it can undermine the trust in the doctor-patient relationship, thereby weakening the therapeutic bond necessary to care for this sick and often vulnerable population.

Preparing caregivers for the death of a loved one: a theoretical framework and suggestions for future research.

Caring for a terminally ill loved one and the death of that person are two of the most stressful human experiences. Recent research suggests that a substantial number of caregivers are unprepared for the death and that these caregivers may be at greater risk of psychological distress. The literature on preparedness and mental health, however, is in its infancy. The purpose of this paper, therefore, is to summarize the literature in order to stimulate discussion and research on preparedness. It is our view that preparedness for the death of a loved one is an important contributor to caregiver well-being and bereavement outcomes and that more work in this area is needed in order to improve the care provided to caregivers of seriously or terminally ill patients. We briefly review the literature on preparedness, present a theoretical model delineating the relationships between preparedness, caregiver-health care provider communication, and caregiver well-being, and provide suggestions for future research.

Manualized communication interventions to enhance palliative care research and training: rigorous, testable approaches.

Palliative care practice requires excellent communication between the patient, family, and clinical team. Experts in the field have proposed a variety of communication interventions that can be used in the palliative care setting. However, these interventions are at a high level of generality: the specifics of each intervention are not well codified; the individual steps in each intervention are not easily reproducible and thus not comparable between practitioners; the methods to measure adherence to these communication protocols have not been established; and there is little detail on how to adapt these general interventions to the individual patient and family. Therefore, we lack good evidence for the efficacy of these recommendations. This paper makes the case for development of structured, testable approaches to communication that will inform clinical practice and communication training. To do so, palliative care communication should be conceived as a formal medical and psychosocial intervention-a potential treatment with risks and benefits to be systematically researched and operationalized in the same manner as medication interventions. As we illustrate, psychotherapy research has faced the same challenges in the past and has utilized manualized treatments to meet its goals. Through such approaches, we can begin to address the most basic intervention questions such as protocol efficacy, dose-response, side effects, and the optimal process and content of communication with the patient and family. The advantages of manualized communication approaches; some concepts underlying manual construction; and challenges to extending manualized communication to the palliative care domain are discussed.
