Fatigue and quality of life outcomes of exercise during cancer treatment.

PURPOSE: Despite the recognition of fatigue as a common and distressing symptom during cancer treatment, there are few evidence-based interventions available to manage such fatigue. The purpose of this multi-institutional pilot study was to explore the effects of a home-based moderate walking exercise intervention on fatigue, physical functioning, emotional distress, and quality of life (QOL) during breast cancer treatment. DESCRIPTION OF STUDY: Fifty-two women were recruited from five university hospital outpatient departments for this pilot study with an experimental design. Subjects were randomly assigned to the walking program or to usual care during adjuvant chemotherapy or radiation therapy for breast cancer. Symptoms, physical functioning, and QOL were measured at baseline, midtreatment, and at the end of treatment. RESULTS: Women who exercised at least 90 minutes per week on 3 or more days reported significantly less fatigue and emotional distress as well as higher functional ability and QOL than women who were less active during treatment. CLINICAL IMPLICATIONS: A home-based walking exercise program is a potentially effective, low-cost, and safe intervention to manage fatigue and to improve QOL during adjuvant chemotherapy or radiation therapy for breast cancer. This health-promoting self-care activity needs further testing in large randomized clinical trials.

Caregiver responses and needs. An ambulatory bone marrow transplant model.

PURPOSE: This longitudinal, descriptive outcomes study was conducted to compare the emotional responses and needs of the caregivers of patients who undergo bone marrow transplantation (BMT) for hematologic malignancies, as observed in an inpatient/outpatient (IPOP) setting with those in an inpatient setting. DESCRIPTION OF STUDY: A convenience sample of 43 caregivers for patients undergoing either autologous or allogeneic BMT was selected from both the inpatient unit (n = 26) and the IPOP ambulatory setting (n = 17). Emotional responses were measured by the Profile of Mood States. The importance and satisfaction of informational, patient-care, and psychological needs were assessed with the Caregiver Needs Survey, a modified version of the Home Cancer Caregiver Needs Survey. Data were collected at six points across the BMT trajectory, from before the procedure to 12 months after. Descriptive statistics were used to report sample characteristics, emotional responses, and needs. Nonparametric statistics were used to compare the IPOP and inpatient caregiver groups, and to identify relationships between emotional responses and needs within groups. RESULTS: IPOP caregivers were found to have significantly less mood disturbance at points before discharge. Both groups showed a decrease in mood disturbance 6 and 12 months after BMT. IPOP caregivers had higher levels of satisfaction of their informational and psychological needs at day 21. Significant correlations between total mood disturbance and satisfaction of informational, psychological, and patient-care needs were found for inpatient caregivers across treatment time points. CLINICAL IMPLICATIONS: These findings support the IPOP model of care as being less emotionally distressing for and better meeting the needs of family caregivers. Specific implications for practice include the importance of caregiver education in the area of patient-care information and of assessment and intervention to meet caregiver psychological needs. Continued evaluation of the impact of changes in care delivery on family caregivers is essential for the provision of comprehensive cancer care.

Establishing mechanisms to conduct multi-institutional research--fatigue in patients with cancer: an exercise intervention.

PURPOSES/OBJECTIVES: To describe the process of establishing a multi-institutional interdisciplinary team of oncology researchers and conducting a pilot study of an exercise intervention for fatigue. DATA SOURCES: Project meeting minutes and records, research team members' logs, subjects' research records, the research study proposal, and team members' individual and collective shared experiences. DATA SYNTHESIS: Site investigators established research teams at five academic medical centers. Fifty subjects were enrolled in the study and tested during their cancer treatment. Study methods, including instrumentation, were evaluated carefully and revised. CONCLUSIONS: The multi-institutional network of researchers is an effective and efficient model for testing an intervention to manage fatigue during cancer treatment. IMPLICATIONS FOR NURSING PRACTICE: Exercise is a feasible and potentially beneficial intervention to combat distressing cancer treatment-related fatigue. A pilot study is essential to determine the best methods for conducting a clinical trial and to develop the teams of researchers necessary for such a project.

Effects of exercise on fatigue, physical functioning, and emotional distress during radiation therapy for breast cancer.

PURPOSES/OBJECTIVES: To test the hypothesis that women participating in a walking exercise program during radiation therapy treatment for breast cancer would demonstrate more adaptive responses as evidenced by higher levels of physical functioning and lower levels of symptom intensity than women who did not participate. DESIGN: Experimental, two-group pretest, post-test. SETTING: Two university teaching hospital outpatient radiation therapy departments. SAMPLE: 46 women beginning a six-week program of radiation therapy for early stage breast cancer. METHODS: Following random assignment, subjects in the exercise group maintained an individualized, self-paced, home-based walking exercise program throughout treatment. The control group received usual care. Dependent variables were measured prior to and at the end of radiation therapy. In addition, symptoms were assessed at the end of three weeks of treatment. MAIN RESEARCH VARIABLES: Participation in the walking exercise program, physical functioning fatigue, emotional distress, and difficulty sleeping. FINDINGS: Hypothesis testing by multivariate analysis of covariance, with pretest scores as covariates, indicated significant differences between groups on outcome measures (p < 0.001). The exercise group scored significantly higher than the usual care group on physical functioning (p = 0.003) and symptom intensity, particularly fatigue, anxiety, and difficulty sleeping. Fatigue was the most frequent and intense subjective symptom reported. CONCLUSIONS: A self-paced, home-based walking exercise program can help manage symptoms and improve physical functioning during radiation therapy. IMPLICATIONS FOR NURSING PRACTICE: Nurse-prescribed and -monitored exercise is an effective, convenient, and low-cost self-care activity that reduces symptoms and facilitates adaptation to breast cancer diagnosis and treatment.

Challenges to behavioral research in oncology.

PURPOSE: The difficulties encountered by investigators in conducting behavioral research with oncology patients have received little attention in the literature. This article provides a practical guide to problems that might be anticipated in the planning and conduct of behavioral research. OVERVIEW: Problems include subject accrual and retention, development of a multidisciplinary research team, control of confounding variables, psychosocial instrumentation issues, and acceptance of the need for behavioral research. Methodological and feasibility issues are examined. Strategies for addressing the issues are presented. CLINICAL IMPLICATIONS: Successful behavioral research in oncology requires firm grounding in clinical practice. Clinicians can improve the quality of research and thus, the scientific base for practice by joining or facilitating multidisciplinary research efforts.

Psychotropic medications. Nursing implications.

The purpose of this article has been to bring together selected critical information for the nurse to use in developing a plan of care for each individual patient in regard to psychotropic medications. The important considerations to keep in mind during assessment, planning, implementation, and evaluation have been discussed, with implications for the nurse in terms of her contribution to the treatment team's planning and evaluation of psychotropic drug therapy. In addition, patient education responsibilities have been addressed. The nurse is in a pivotal position to contribute significantly to the therapeutic effectiveness of each psychotropic medication treatment plan.
