Psychosocial interventions in adult patients with coronary heart disease and cancer. A literature review

Improving diabetes management with mobile health technology

Diabetes affects 25.8 million persons in the United States, and these persons make more than 35 million ambulatory care visits annually. Yet, less than half of persons with diabetes meet the recommended levels of A1C, blood pressure and lipid control. One innovative approach is to use mobile health technologies to help patients better manage their diabetes and related conditions, and 85% to 90% of patients have access to mobile health technology. A brief review of the guidelines for diabetes care and mobile health technology that can support the guidelines are reported related to (1) glycemic control and self-monitoring of blood glucose, (2) pharmacological approaches and medication management, (3) medical nutrition therapy, (4) physical activity and resistance training, (5) weight loss, (6) diabetes self-management education and (7) blood pressure control and hypertension. The patient and provider are encouraged to explore possibilities for mobile health technologies that can support behavior change.

What is a psychological intervention? A metareview and practical proposal

OBJECTIVE

What do we mean by a 'psychological intervention' in the context of cancer care? It is critical to know what treatments are included under this term, if data from diverse treatment trials are to be summarized in order to inform clinical practice. We, therefore, aimed to determine how the term 'psychological intervention' has been defined and used to group and compare interventions in reviews of cancer care.

METHODS

We conducted a review of existing reviews (a metareview). These included systematic and narrative reviews and meta-analyses of interventions that were described as 'psychological', with the aim of determining: (a) the definitions for 'psychological interventions' that were used and (b) the treatments that were included within this category.

RESULTS

We identified 66 relevant reviews. Surprisingly, we were unable to find any explicit definition of the term 'psychological intervention' in these reviews. The reviews included 79 different treatments with little consistency between reviews in which treatments were included.

CONCLUSIONS

There is confusion about what 'psychological intervention' means in the cancer review literature. A clearer definition is essential to summarize research findings. We propose that rather than simply grouping interventions as 'psychological', it would be more useful if reviews focussed on specified domains of the interventions, namely content, proposed mechanism, target outcome, and methods of delivery. This would enable greater specificity in the review question, more meaningful comparisons, and would hopefully provide clearer answers for the readers of the reviews. A checklist for the summarizing of reports of interventions for review is provided.

Effects of a multifaceted psychiatric intervention targeted for the complex medically ill: a randomized controlled trial

BACKGROUND

This study evaluated a multifaceted psychiatric intervention targeted at the complex medically ill identified by means of the INTERMED, an instrument to assess case complexity.

METHODS

Of 885 rheumatology inpatients and diabetes outpatients who were assessed for eligibility, 247 were identified as complex (INTERMED score >20) and randomized to the intervention (n = 125, 84 rheumatology and 41 diabetes patients) or care as usual (n = 122, 78 rheumatology and 44 diabetes patients). For the majority of the cases the multifaceted intervention consisted of an intervention conducted by a psychiatric liaison nurse and/or of referral to a liaison psychiatrist, followed by advice to the treating physician or organization of a multidisciplinary case conference. Baseline and follow-up at months 3, 6, 9 and 12 measured prevalence of major depression (Mini-International Neuropsychiatric Interview), depressive symptoms (Center for Epidemiological Studies Depression Rating Scale), physical and mental health (SF-36), quality of life (EuroQol), health care utilization and HbA(1c) levels (diabetic patients).

RESULTS

Prevalence of major depression was reduced from 61% (T0) to 28% (T4) in the intervention group and remained stable in care as usual (57% at T0 to 50% at T4). Compared to care as usual, significant improvement over time was observed in the intervention group with regard to depressive symptoms (F = 11.9; p = 0.001), perception of physical (F = 5.7; p = 0.018) and mental health (F = 3.9; p = 0.047) and quality of life (F = 21.8; p < 0.001). Effects tended to be stronger in diabetes patients, in patients with baseline major depression and in patients with moderate INTERMED scores. Finally, hospital admissions occurred less often in the intervention group, reaching statistical significance for the period between 6 and 9 months of follow-up (p = 0.02).

CONCLUSIONS

The results suggest that a psychiatric intervention targeted for complex medical patients can improve health outcomes.

A multidimensional cancer rehabilitation program for cancer survivors: effectiveness on health-related quality of life

OBJECTIVE

A multidimensional rehabilitation program for cancer survivors was developed to overcome cancer-related problems and to improve quality of life. The two purposes of the study were to describe the effectiveness of the program and to obtain information about patient preferences for multi or mono dimensional rehabilitation programs.

SUBJECTS

cancer survivors with different diagnoses, and cancer-related physical and psychosocial problems.

INTERVENTION

a 15-week rehabilitation program including individual exercise, sports, psycho-education, and information. Group-wise randomization was implemented by assigning one half of the patients to the complete program while the other half were allowed to choose which program components they considered relevant.

MEASURES

Health-Related Quality of Life [RAND-36 and Rotterdam Symptom Check List (RSCL)], exercise capacity (symptom limited bicycle ergometry), muscle force (hand-held dynamometry), and patient preferences. Measurements were performed before (T0) and after the rehabilitation program (T1), and at a 3-month follow-up (T2).

RESULTS

After the rehabilitation program, cancer survivors (n=63) displayed statistically significant improvements on health-related quality of life with effect sizes (ES) varying from 0.38 to 0.99 (RAND-36) and from -0.34 to -0.57 (RSCL), most persistent at 3-month follow-up. Furthermore, statistically significant improvements in exercise capacity and muscle force of upper and lower extremities were displayed after rehabilitation. If offered a choice, 80% of the patients prior to start and 58% of the patients after completion of the program indicated that they preferred the entire multidimensional program.

CONCLUSION

A multidimensional rehabilitation program has statistically and clinically relevant beneficial effects on health-related quality of life, exercise capacity, and muscle force in cancer patients with different diagnoses. Furthermore, if offered the choice, the majority of cancer survivors seem to prefer multidimensional programs to programs with only one component.

Physical functioning and quality of life after cancer rehabilitation

In order to overcome cancer-related problems and to improve quality of life, an intensive multi-focus rehabilitation programme for cancer patients was developed. We hypothesised that this six-week intensive rehabilitation programme would result in physiological improvements and improvement in quality of life. Thirty-four patients with cancer-related physical and psychosocial problems were the subjects of a prospective observational study. A six-week intensive multi-focus rehabilitation programme consisted of four components: individual exercise, sports, psycho-education, and information. Measurements (symptom-limited bicycle ergometry performance, muscle force and quality of life [RAND-36, RSCL, MFI]) were performed before (T0) and after six weeks of rehabilitation (T1). After the intensive rehabilitation programme, statistically significant improvements were found in symptom-limited bicycle ergometry performance, muscle force, and several domains of the RAND-36, RSCL and MFI. The six-week intensive multi-focus rehabilitation programme had immediate beneficial effects on physiological variables, on quality of life and on fatigue.

Home-based versus hospital-based cardiac rehabilitation after myocardial infarction or revascularisation: design and rationale of the Birmingham Rehabilitation Uptake Maximisation Study (BRUM): a randomised controlled trial [ISRCTN72884263]

BACKGROUND

Cardiac rehabilitation following myocardial infarction reduces subsequent mortality, but uptake and adherence to rehabilitation programmes remains poor, particularly among women, the elderly and ethnic minority groups. Evidence of the effectiveness of home-based cardiac rehabilitation remains limited. This trial evaluates the effectiveness and cost-effectiveness of home-based compared to hospital-based cardiac rehabilitation.

METHODS/DESIGN

A pragmatic randomised controlled trial of home-based compared with hospital-based cardiac rehabilitation in four hospitals serving a multi-ethnic inner city population in the United Kingdom was designed. The home programme is nurse-facilitated, manual-based using the Heart Manual. The hospital programmes offer comprehensive cardiac rehabilitation in an out-patient setting.

PATIENTS

We will randomise 650 adult, English or Punjabi-speaking patients of low-medium risk following myocardial infarction, coronary angioplasty or coronary artery bypass graft who have been referred for cardiac rehabilitation.

MAIN OUTCOME MEASURES

Serum cholesterol, smoking cessation, blood pressure, Hospital Anxiety and Depression Score, distance walked on Shuttle walk-test measured at 6, 12 and 24 months. Adherence to the programmes will be estimated using patient self-reports of activity.In-depth interviews with non-attendees and non-adherers will ascertain patient views and the acceptability of the programmes and provide insights about non-attendance and aims to generate a theory of attendance at cardiac rehabilitation. The economic analysis will measure National Health Service costs using resource inputs. Patient costs will be established from the qualitative research, in particular how they affect adherence.

DISCUSSION

More data are needed on the role of home-based versus hospital-based cardiac rehabilitation for patients following myocardial infarction and revascularisation, which would be provided by the Birmingham Rehabilitation Uptake Maximisation Study (BRUM) study and has implications for the clinical management of these patients. A novel feature of this study is the inclusion of non-English Punjabi speakers.

Baseline health-related quality of life in postmenopausal women with coronary heart disease: the Estrogen Replacement and Atherosclerosis (ERA) trial

OBJECTIVES

This study examined the baseline health-related quality of life (HRQL) of 301 postmenopausal women with heart disease enrolled in the Estrogen Replacement and Atherosclerosis (ERA) trial.

METHODS

The primary measure of HRQL was the Medical Outcomes Study Short Form-36 (MOS SF-36). The SF-36 was augmented with secondary assessments, including measures of depressive symptoms, life satisfaction, urinary incontinence, sleep disturbance, and physical symptoms. Multiple regression analyses were used to test hypotheses regarding the contribution of positive (social support) and negative (social strain) aspects of social relations after accounting for other correlates of HRQL and heart disease.

RESULTS

Results indicate that social support was positively associated with better functioning for all measured outcomes (all p < 0.05) except symptom frequency and severity. Social strain was negatively associated with HRQL functioning (all p < 0.05) except overall physical functioning, sleep disturbance, and urinary incontinence. In addition, several comorbid conditions were negatively associated with HRQL outcomes. In particular, chest pain was significantly associated with worse functioning on all HRQL outcomes except urinary incontinence.

CONCLUSIONS

These data suggest that both clinical status variables (particularly chest pain) and the psychosocial context (represented by dimensions of relationship quality) influenced HRQL in this cohort. Thus, interventions that combine medical treatments with psychosocially based interventions may be most effective for women at risk for impaired HRQL.

Can we talk? Developing a social support nursing intervention for couples

Social support is an important influence on success during lifestyle modification attempts. According to the theory of expressed emotion, support that is perceived by the recipient as critical or overprotective is unhelpful and perhaps harmful. This article describes an intervention for couples and preliminary assessment of its feasibility and acceptability by the nurses who trialed it. Four staff nurses and 2 advanced practice nurses administered the intervention to 15 couples and reported on the benefits and limitations of the intervention. One individual in each couple had a chronic or an acute cardiac illness. The nurses perceived the intervention as valuable; even a single session stimulated discussion between the couple about important issues. Complexity, logistic barriers, and time constraints limited the technique. The authors conclude that this intervention may be most useful to clinical nurse specialists who have additional education, training in communication, and teaching and consulting skills.

Telephone counseling in psychosocial oncology: a report from the Cancer Information and Counseling Line

Providing psychosocial counseling services to cancer patients and their significant others by telephone is emerging as an alternative to traditional (in-person) counseling programs in psychooncology. In this paper, data are reported describing the clients of such a program that has been in continuous operation since 1981: the Cancer Information and Counseling Line (CICL) of the AMC Cancer Research Center. An examination of call record forms completed between 1 June 1998 and 30 May 1999 (N = 1627) revealed that the vast majority of callers were female (77%), non-Hispanic White (77%), with at least some college education (62%). Only 27% were cancer patients/survivors, compared to 43% who were spouses, other relatives and friends of cancer patients/survivors, and 16% who were symptomatic callers. Breast cancer was by far the most frequently mentioned cancer site (30%). Although initial topics of inquiry were dominated by requests for medical information (77%), with only a small percentage of callers initially requesting psychosocial support and counseling (12%), by the time, the call was completed, 67% had received some form of psychosocial support and/or counseling. Recommendations for future research are discussed within the context of this review.

Health psychology: psychosocial and biobehavioral aspects of chronic disease management

Psychosocial factors appear to impact upon the development and progression of such chronic diseases as coronary heart disease, cancer, and HIV/AIDS. Similarly, psychosocial interventions have been shown to improve the quality of life of patients with established disease and seem to influence biological processes thought to ameliorate disease progression. Small-scale studies are useful for specifying the conditions under which psychosocial factors may or may not impact quality of life, biological factors, and disease progression. They are also useful for informing us about the conditions under which psychosocial interventions can serve as adjuvants (e.g. adherence training) to medical treatments. Only large-scale clinical trials, however, can determine the extent to which these psychosocial interventions may impact morbidity and mortality.

Exercise-based rehabilitation for coronary heart disease

BACKGROUND

The burden of cardiovascular disease world-wide is one of great concern to patients and health care agencies alike. Cardiac rehabilitation aims to restore patients with heart disease to health through exercise only based rehabilitation or comprehensive cardiac rehabilitation.

OBJECTIVES

To determine the effectiveness of exercise only or exercise as part of a comprehensive cardiac rehabilitation programme on the mortality, morbidity, health-related quality of life (HRQoL) and modifiable cardiac risk factors of patients with coronary heart disease.

SEARCH STRATEGY

Electronic databases were searched for randomised controlled trials, using standardised trial filters, from the earliest date available to December 31st 1998.

SELECTION CRITERIA

Men and women of all ages, in hospital or community settings, who have had myocardial infarction, coronary artery bypass graft or percutaneous transluminal coronary angioplasty, or who have angina pectoris or coronary artery disease defined by angiography.

DATA COLLECTION AND ANALYSIS

Studies were selected independently by two reviewers, and data extracted independently. Authors were contacted where possible to obtain missing information.

MAIN RESULTS

This systematic review has allowed analysis of an increased number of patients from approximately 4500 in earlier meta-analyses to 8440 (7683 contributing to the total mortality outcome). The pooled effect estimate for total mortality for the exercise only intervention shows a 27% reduction in all cause mortality (random effects model OR 0.73 (0.54, 0.98)). Comprehensive cardiac rehabilitation reduced all cause mortality, but to a lesser degree (OR 0.87 (0.71, 1.05)). Total cardiac mortality was reduced by 31% (random effects model OR 0.69 (0.51, 0.94)) and 26% (random effects model OR 0.74 (0.57, 0.96)) in the exercise only and comprehensive cardiac rehabilitation groups respectively. Neither intervention had any effect on the occurrence of non-fatal myocardial infarction. There was a significant net reduction in total cholesterol (pooled WMD random effects model -0.57 mmol/l (-0.83, -0.31)) and LDL (pooled WMD random effects model -0.51 mmol/l (-0.82, -0.19) in the comprehensive cardiac rehabilitation group.

REVIEWER'S CONCLUSIONS

Exercise-based cardiac rehabilitation is effective in reducing cardiac deaths. It is not clear from this review whether exercise only or a comprehensive cardiac rehabilitation intervention is more beneficial. The population studied in this review is still predominantly male, middle aged and low risk. Identification of the ethnic origin of the participants was seldom reported. It is possible that patients who would have benefited most from the intervention were excluded from the trials on the grounds of age, sex or co-morbidity.

Psychological treatments in cardiac rehabilitation: review of rationales and outcomes

OBJECTIVE

In this review, the place of psychological interventions in cardiac rehabilitation and differences in underlying rationales are presented. Treatment approaches vary in that some practitioners favor biobehavioral approaches with strong relaxation/breathing components, whereas others offer unstructured support, psychoeducation to maximize compliance, or psychological interventions directed at reducing emotional distress.

METHODS

The effectiveness of psychosocial rehabilitation for endpoints like mortality, recurrence, emotional distress, and intermediate hard endpoints is reviewed by integrating conclusions from narrative and meta-analytic reviews as well as recent major clinical trials.

RESULTS

The aggregated findings support the use of psychosocial interventions and they also help to explain critical differences in outcome in that studies which fail to reduce distress also fail to lead to reduced mortality or reduced event recurrence.

CONCLUSION

Gender differences in outcome and recent trends in cardiology are discussed because both have distinct consequences for the effective delivery of psychological services to cardiac patients.

Screening for anxiety and depression in adult general medical in-patients in a Scottish District General Hospital

We prospectively screened for anxiety and depression by administering the HAD scale to consecutive general medical patients admitted to a Scottish District General Hospital (DGH) over a calendar month. Age, gender, and use of psychotropic medications were also recorded. Of 119 patients (49 male) aged 16 to 92 years, "Probable presence of anxiety" was recorded in 23%, and "Probable presence of depression" in 19%. There was no significant difference between male and female patients or between different age groups. Formal psychological management was not available on site. Sixty-seven per cent of patients with "Probable presence of anxiety" and 61% with "Probable presence of depression" received no psychotropic medications. Despite a high prevalence of psychological distress amongst general medical in-patients, anxiety and depression are consistently under-diagnosed and under-treated. Screening for psychological distress, followed, where indicated, by psychological and/or pharmacological intervention, should be a fundamental element of holistic, patient-centred care in general medicine.

Planning psychosocial care for cancer patients: if at first you don't succeed, shift your paradigm

Concerned with our capacity to bridge the gap between patients' and families' psychosocial needs and the services provided, we developed a psychosocial intake and referral service. This paper will describe the lessons learned in trying to introduce an innovation whose time had not yet come and, after analyzing the outcome, to present a new approach to planning. The service was not approved and, on reflection, eight factors were identified as contributing to the failure of the service to reach fruition. In light of what we learned, we developed a new planning model that reflects planning as a circular, iterative process rather than as a linear process.

Behavioral research to enhance adjustment and quality of life among adults with cancer

The purpose of this article is to recommend future directions for behavioral research to enhance adjustment and quality of life for adults diagnosed with cancer. As context for the recommendations, the domain of behavioral research in psychosocial oncology is briefly described, the state of the science measuring quality of life is summarized, and research results from behavioral research on quality of life are reviewed.

Communication skills and psychological training in oncology

Preserving the best possible quality of life for cancer patients and their families has become a major goal in cancer care. However, the cumulative effect of stressors related to cancer care, many of which involve communicating with patients and relatives, may lead to the development of burnout in staff. Many health care professionals lack the psychosocial knowledge and communications skills needed to identify patients' problems because general professional training focuses on technical care. Teaching strategies known as psychological training programs (PTP) are therefore being developed to help improve health care professionals' sensitivity to communication problems with patients and relatives. Cognitive (e.g. theoretical information), experiential (e.g. case-history discussions), behavioural (e.g. role-playing exercise) and supportive (e.g. stressor identification) training techniques are used to teach the essential skills of good communication, i.e. listening, empathy, response to cues and appropriate use of reassurance. PTP range from one-day courses and residential workshops to full-time 1- or 2-year curricula. However, one of the main obstacles to implementing PTP is scepticism among health care professionals about its usefulness. Research on training effectiveness should therefore be developed to assess the impact of communication skills on quality of care and patients' quality of life.

Psychodynamic psychotherapy for cancer patients

Psychodynamic psychotherapy is effective as an approach to understanding the psychological conflicts and the psychiatric symptoms of cancer patients as well as to planning useful psychological interventions. The author recommends that the psychotherapist who treats cancer patients be familiar with the following: 1) the natural course and treatment of the illness, 2) a flexible approach in accord with the medical status of the patient, 3) a common sense approach to defenses, 4) a concern with quality-of-life issues, and 5) counter-transference issues as they relate to the treatment of very sick patients. Case reports illustrate the unique problems facing psychotherapists who are treating cancer patients. Further, these cases show the effective use of psychodynamic principles to inform the therapist of successful psychotherapeutic interventions.

Baseline quality of life as a predictor of mortality and hospitalization in 5,025 patients with congestive heart failure. SOLVD Investigations. Studies of Left Ventricular Dysfunction Investigators

This study examined the independent relation of health-related quality of life (HRQL) to mortality and congestive heart failure (CHF)-related hospitalizations in patients with an ejection fraction of < 0.35 followed for a mean of 36.5 months. A brief HRQL questionnaire was administered at baseline to patients randomized to placebo or enalapril in the Studies of Left Ventricular Dysfunction (SOLVD) trial. Participants had an ejection fraction of < 0.35 and either symptomatic CHF (treatment trial, n = 2,465) or asymptomatic CHF (prevention trial, n = 2,560). Baseline assessment of HRQL predicted mortality and CHF-related hospitalizations in symptomatic and asymptomatic patients randomized to enalapril and placebo treatment. Domains that were the stronger univariate predictors of mortality and CHF-related hospitalizations were activities of daily living (relative risk [RR] for mortality: 1.163, p < 0.000; for hospitalization: 1.215, p < 0.000), general health (RR for mortality: 1.205, p < 0.000; for hospitalization: 1.188, p < 0.000), and social functioning (RR for mortality 1.098, p < 0.000; for hospitalization: RR 1.156, p < 0.000). In the multivariate model, activities of daily living (RR for mortality 1.41, p < 0.000; for hospitalization: RR 1.43, p < 0.002), general health (RR for mortality 1.21, p < 0.000; for hospitalization RR 1.16, p < 0.013) and heart failure symptoms (RR for mortality 1.02, p < 0.025; for hospitalization RR 1.03, p < 0.004) were found to be independent risk factors. HRQL independently predicted mortality and CHF-related hospitalizations after adjustment for ejection fraction, age, treatment, and New York Heart Association classification in patients with an ejection fraction of < 0.35, randomized to enalapril and placebo treatment. HRQL provides additional clinical information regarding disease course and outcome that is not captured by traditional indexes of clinical status.

Psychiatric interventions in the medically ill. Outcome and effectiveness research

This article reviews the current status and emerging trends of outcome data from research studies of psychiatric and psychosocial interventions for mental disorders in patients in the general medical sector. Although data from such studies have had limited success to date in influencing health policy, legislators and administrators are increasingly likely to turn to outcome data to inform their decisions. The impact of psychiatric disorders, the recognition and treatment or referral of psychiatric-disordered patients by general medical practitioners, and the outcome results of psychiatric intervention programs are examined for both the inpatient and outpatient general medical sectors.

Group cognitive behavioural therapy interventions with cancer patients: a review of the literature

At present there is considerable evidence that suggests cancer patients, once diagnosed, experience significant and long-term psychosocial problems. Several studies have evaluated group interventions, but only a few have used group cognitive behavioural therapy (GCBT) with cancer patients. The following paper represents a review of the literature of GCBT, illustrating the key findings from these studies.

Rehabilitation of the cancer patient at home

OBJECTIVES

To provide a framework for considering home nursing care of the cancer patient within the context of cancer rehabilitation and to briefly review various aspects of cancer rehabilitation.

DATA SOURCES

Review articles and reference books of current and classic works that discuss cancer rehabilitation.

CONCLUSIONS

Rehabilitation is an important concept that should transcend cancer care in all settings, and one that naturally fits with home care. The effects of cancer and cancer treatment on the individual's quality of life, eg, psychological and social factors, sexual functioning, nutrition, fitness and exercise, symptom management, and physical disabilities are important considerations in the rehabilitation needs of persons with cancer.

IMPLICATIONS FOR NURSING PRACTICE

It is the challenge of the home health nurse to promote optimal functioning of cancer patients in their home environment. Assessment of the cancer patient's rehabilitation needs, skilled interventions, establishment of realistic goals, and coordinating care between members of the rehabilitation team are major responsibilities.

Group cognitive behavioural therapy: an intervention for cancer patients

There is considerable evidence to suggest that cancer patients, including those with advanced disease, experience significant and long-term psychosocial problems. Work using group cognitive behavioural therapy with cancer patients has recently demonstrated a way in which it may be possible to treat emotionally distressed individuals effectively. This article reviews the literature on group cognitive behavioural psychotherapy and discusses for practitioners of all disciplines the important techniques, the value of time-limited interventions, the type of patients who may benefit, and where and how to facilitate successful interventions. Health workers with an interest in the emotional care of patients are thus provided with some understanding of the value that group cognitive behavioural psychotherapy may hold for them.

On organizing an international workshop on psychotherapeutic interventions in cancer patients. A virtual coffeebreak communication

This paper is an unusual summary of my thoughts on the International Workshop on Psychotherapeutic Interventions in Cancer Patients in Flims, Switzerland, in 1995. Based upon virtual coffeebreak communications, I try to explain to my virtual partner how the idea of the workshop developed, how I came to select participants and experts, and why the workshop was structured in such a specific way. Concerning the workshop itself I shall quote personal feedback statements from participants, drawing upon the impressions they took with them from demonstration workshops prepared by the leading experts in the field. During the workshop the impact of psychosocial interventions upon survival was critically evaluated, whereas it was unanimously agreed that the most important target of psychosocial interventions in cancer patients is the improvement in quality of life. After the workshop I personally decided to enhance my professional engagement in the area of helping clinical oncologists and nurses to improve on the psychosocial skills they need in caring for cancer patients.

Complementary cancer treatments: hope or hazard?

Complementary therapies are frequently used by cancer patients, yet the area is a minefield of hazards and hopes. A distinction between cure and care seems helpful. There are no effective complementary cures and most options that are promoted carry a distinct and, in certain cases, fatal risk. Complementary cancer care is more acceptable and there are options that can be shown to ease suffering. Vis a vis the popularity of complementary cancer treatments, the lack of scientific evidence for most therapies seems unacceptable. The call for more rigorous research is loud and clear.

Progressive muscle relaxation and guided imagery in cancer patients

The aim of this study was to gather information on the immediate and long-term effects of six sessions of group Progressive Muscle Relaxation with Guided Imagery on the psychological distress of self-referred cancer patients. Patients' psychological distress and coping with cancer were assessed by three self-reports: the Multiple Locus of Control, the Impact of Events Scale (IES), and the Brief Symptom Inventory (BSI). Of the 123 patients who started group therapy, 37 dropped out during its course. The 86 patients who completed the intervention showed marked improvement on both BSI and IES, an improvement maintained over the next 6 months in 58 patients who continued assessment through the followup period.

Psychiatric comorbidity and length of stay in the general hospital. A critical review of outcome studies

The authors critically reviewed 26 international and American outcome studies that assessed the effect of psychiatric comorbidity on length of stay for medical/surgical inpatients. Three generations of American studies were defined according to the rigorousness of the methodology. Eighty-nine percent of all studies with sample sizes greater than 110 and 75% of the prospective, rigorously controlled, American studies found a significant association between psychiatric comorbidity and increased length of stay. The findings lead to the conclusion that impaired cognition associated with delirium and dementia, depressed mood, and other personality variables contributes to prolonged hospital stays and greater utilization of hospitals and other health resources after discharge. Recommendations for future research are suggested.

The etiology of psychiatric symptoms in patients with systemic lupus erythematosus

The purpose of this review was to explore the probable etiologies of psychiatric problems in patients with SLE. Although instances of psychosis generally are attributed to disease pathophysiology, the precise mechanism for this problem remains speculative. The etiology of non-psychotic psychiatric complaints is even less clear. Overall, it is likely that psychiatric complaints in patients with SLE are attributable to numerous factors including acquired brain dysfunction, organ system dysfunction, iatrogenic effects of corticosteroid treatment, learning history, psychosocial stressors, and current coping strategies. Additional research is needed to explore the bi-directional, synergistic, and dynamic interactions among diverse physiological and psychological variables as they impact an individual's psychiatric status.

Psychosocial interventions in chronic medical illness. An overview of outcome research

Previous studies have shown that psychopathology is common in the medically ill, affects the course of medical illness, and is associated with increased health care costs. Recent controlled trials have demonstrated that psychosocial interventions in the medically ill can improve both psychosocial and medical outcomes. Although an important aim of current research is to assess the cost effectiveness of such interventions, the meaning and significance of "cost effectiveness," "cost benefit," and "cost offset" are frequently misunderstood. An overview of outcome research will be used to illuminate the promise and the limitations of such studies, with special attention to bias in research design.
