Unmet supportive care needs in prostate cancer survivors with advanced disease: A mixed-methods exploration.

Purpose: Men with advanced prostate cancer experience a wide range of side effects from the cancer and its therapies, which have a negative effect on their quality of life (QOL). Few studies have evaluated supportive care needs in these individuals. The purpose of this study was to conduct a holistic supportive care needs assessment among these survivors guided by the Supportive Care Framework for Cancer Care. Methods: Using a convergent parallel mixed-methods approach, prostate cancer survivors with advanced disease (n = 188) completed a cross-sectional survey. A subset of these survivors (n = 20) participated in an interview to further explore their experience of unmet needs. Results: Survivors reported unmet supportive care needs in every domain of the framework. Up to 95.2% of the survivors had at least one unmet need, with a mean of 14.9 (range: 0-42). Several areas of convergence among the quantitative and qualitative data (fatigue, sexual dysfunction, practical, and emotional/psychological domains), as well as divergence (informational and spiritual domains, depression, urinary dysfunction) were found through the integration process. Conclusions: This study confirms that prostate cancer survivors with advanced disease experience high rates of unmet supportive care needs. The findings also highlight the diversity of those unmet needs. These results may assist with future development of patient-centered supportive care interventions that better meet the specific needs of this vulnerable group of cancer survivors.

The symptom phenotype of oncology outpatients remains relatively stable from prior to through 1 week following chemotherapy.

Some oncology outpatients experience a higher number of and more severe symptoms during chemotherapy (CTX). However, little is known about whether this high risk phenotype persists over time. Latent transition analysis (LTA) was used to examine the probability that patients remained in the same symptom class when assessed prior to the administration of and following their next dose of CTX. For the patients whose class membership remained consistent, differences in demographic and clinical characteristics, and quality of life (QOL) were evaluated. The Memorial Symptom Assessment Scale (MSAS) was used to evaluate symptom burden. LTA was used to identify subgroups of patients with distinct symptom experiences based on the occurrence of the MSAS symptoms. Of the 906 patients evaluated, 83.9% were classified in the same symptom occurrence class at both assessments. Of these 760 patients, 25.0% were classified as Low-Low, 44.1% as Moderate-Moderate and 30.9% as High-High. Compared to the Low-Low class, the other two classes were younger, more likely to be women and to report child care responsibilities, and had a lower functional status and a higher comorbidity scores. The two higher classes reported lower QOL scores. The use of LTA could assist clinicians to identify higher risk patients and initiate more aggressive interventions.

Review article: self-report measures to evaluate constipation.

BACKGROUND: Constipation is a subjective phenomenon, and as such must be evaluated using patient self-report. Valid and reliable measures of constipation are essential to standardize the diagnosis, assess the severity and evaluate the effectiveness of treatments. AIM: To compare and contrast published self-report measures of constipation in terms of development, content, general characteristics, psychometric properties and clinical utility. METHODS: MEDLINE (1966-2007), CINAHL (1980-2007), Cochrane (1993-2007) and Web of Science (1995-2007) were searched to identify self-report measures of constipation. Measures of constipation were selected if they: (i) were self-report measures that measured only constipation; (ii) had undergone psychometric testing; (iii) were used in adults and (iv) were written in English. RESULTS: Seven self-report measures of constipation were identified. The content areas evaluated by these measures varied. Only two measures had adequate validity and reliability, sensitivity to change, or were tested in more than one sample. CONCLUSIONS: Findings from this review suggest that the Chinese Constipation Questionnaire and the Patient Assessment of Constipation-Symptom Questionnaire demonstrate adequate psychometric properties for a constipation measure. Additional research is warranted to refine or develop a more comprehensive self-report measure to evaluate constipation in adults.

Lack of adherence with the analgesic regimen: a significant barrier to effective cancer pain management.

PURPOSE: To evaluate oncology outpatients' level of adherence to their analgesic regimen during a 5-week period. PATIENTS AND METHODS: A random sample of 65 adult oncology outpatients with a Karnofsky performance status score of >or= 50, an average pain intensity score of >or= 2.5, and radiographic evidence of bone metastasis were recruited for this longitudinal study from seven outpatient settings. On a daily basis, patients rated their level of pain intensity and recorded pain medication intake. Adherence rates for opioid analgesics prescribed on an around-the-clock (ATC) and on an as-needed (PRN) basis were calculated on a weekly basis. RESULTS: Overall adherence rates for ATC opioid analgesics ranged from 84.5% to 90.8% and, for PRN analgesics, from 22.2% to 26.6%. No significant differences over time were found in either of these adherence rates. CONCLUSION: One factor that seems to contribute to ineffective cancer pain management is poor adherence to the analgesic regimen.

Measurement of opioid-induced sedation.

One of the major side effects of opioid analgesics is sedation. Despite the fact that neither a universal definition nor a gold standard for the measurement of opioid-induced sedation exists, various neurophysiologic and psychomotor measures are used to quantify the sedative effects of opioids. This report reviews the strengths and weaknesses of various approaches that are used to measure opioid-induced sedation. The first section summarizes various neurophysiologic measures (i.e., electroencephalogram, autonomic reflexes, and evoked responses), and the second section reviews psychomotor measures (i.e., visual analog scales, observer assessments, motor performance tests, tests of perceptual processes, tests of information processing, tests of memory, and composite tests) that are used to evaluate the sedative effects of opioids. Implications for future research on opioid-induced sedation are discussed.

New approaches for evaluating the quality of cancer pain management in the outpatient setting.

Both retrospective and prospective methods can be used to evaluate the quality of cancer pain management in the outpatient setting. Retrospective evaluations of the quality of cancer pain management in the outpatient setting provide benchmark data that can be used to change clinical practice for groups of patients or for specific types of cancer pain problems. Prospective evaluations of the quality of cancer pain management with patient diaries in the outpatient/home care setting can help clinicians do "real-time" evaluations and modify the pain management plan for individual patients. This report provides practical suggestions for evaluating the quality of cancer pain management in the outpatient setting.

Biology of mucosal pain.

Pain is experienced when injury to mucosal tissues occurs. Although the neurobiology of mucosal pain has not been fully elucidated, research has demonstrated that the oral mucosa contains primary afferent nociceptors that respond to thermal, mechanical, and chemical stimuli. Inflammation occurs during the initial phase of mucosal injury caused by stomatotoxic chemotherapy or radiation therapy. This article reviews the mechanisms that underlie acute pain in inflamed cutaneous tissue and summarizes the major mediators that activate and sensitize primary afferent nociceptors. Recommendations for future research to elucidate the neurobiology of mucosal pain throughout the gastrointestinal tract are presented.

Definition of and mechanism for opioid-induced sedation.

Although sedation is acknowledged to be one of the most common side effects of opioid analgesics, the mechanisms and characteristics of this phenomenon remain elusive, and research in this area is extremely limited. This report integrates research findings on the mechanism of action of opioids with research findings on the phenomenon of consciousness to develop a model of how opioids may act in the central nervous system to produce sedation. Based on this integration, a definition of opioid-induced sedation is proposed to encourage dialogue and research on this perplexing and clinically significant phenomenon.

A comparison of the affective state and quality of life of chemotherapy patients who do and do not develop chemotherapy-induced oral mucositis.

The purpose of this longitudinal study was to compare the quality of life and affective state of patients receiving chemotherapy who developed oral mucositis to patients who did not. Outpatients had their mouths assessed at the beginning of their chemotherapy, completed the Multidimensional Quality of Life scale, Cancer version (MQOLS-CA) and the Profile of Mood States (POMS). Patients again completed the MQOLS-CA and POMS if they developed mucositis during their three cycles (monthly), or if they did not and were exiting the study. Seventy-seven outpatients completed the study; 28 patients developed mucositis and 49 did not. The MQOLS-CA total scores for the entire sample decreased significantly over time (F(1,75) = 25.44, P < 0.001), but there was no group by time interaction, i.e., the change in MQOLS-CA total scores did not depend on mucositis status. While the POMS Total Mood Disturbance scores for the entire sample increased significantly over time (F(1,75) = 19.55, P < 0.001), there was a significant group by time interaction (F(1,75)= 4.85, P = 0.03). Patients who developed mucositis had a significant increase in mood disturbance compared to patients who did not. Further, the POMS subscales of depression and anger showed the same pattern of significant increases. In conclusion, the development of mucositis adversely affected the outpatients' affective states, but not their QOL.

Symptom clusters and their effect on the functional status of patients with cancer.

PURPOSE/OBJECTIVES: To determine the effect of the symptom cluster of pain, fatigue, and sleep insufficiency on functional status during three cycles of chemotherapy. DESIGN: Prospective, longitudinal. SETTING: 23 outpatient offices and clinics. SAMPLE: 93 patients with cancer. The typical participant was female (72%), married/partnered (65%), white (87%), and middle-aged (55.4 years), with an average of 14.8 years of education. METHODS: The Quality of Life-Cancer (QOL-CA) version instrument and the Karnofsky Performance Scale (KPS) were completed by 93 outpatients receiving chemotherapy at baseline (Time 1) and at the end of the third cycle (Time 2). Three items (pain, tires easily, sleeps enough to meet needs) from the QOL-CA questionnaire were used to measure the symptom cluster. MAIN RESEARCH VARIABLES: Symptom cluster, outcome, functional status, chemotherapy. FINDINGS: A hierarchical multiple regression model explained 48.4% of the variance in functional status. The KPS at Time 1 explained 30.8% of the variance in KPS at Time 2 (p < 0.001). After KPS at Time 1 was partialled out from KPS at Time 2, the four independent variables entered in the next step were considered predictors of the change in functional status between Time 1 and Time 2. Age explained 11.8% of the change (p = 0.001), pain explained 10.7% of the change (p = 0.002), and fatigue explained 7.3% of the change (p = 0.011). Sleep insufficiency statistically was not significant, only explaining 1% of the change (p = 0.344). CONCLUSION: This study provides beginning insights into the effect of a symptom cluster on patients' functional status. IMPLICATIONS FOR NURSING PRACTICE: Healthcare professionals need to be aware of the presence of symptom clusters and their possible synergistic adverse effect on patients' future morbidity.

A pilot study of the relationship between discomfort and agitation in patients with dementia.

People with dementia often have painful conditions that go unnoticed because of their communication problems. Signs of pain in this population may include agitation and observable behaviors associated with discomfort. Agitation, discomfort, and severity of dementia were evaluated in 33 Veterans Affairs nursing home patients using the Cohen-Mansfield Agitation Inventory, the Discomfort Scale, and the Global Deterioration Scale, respectively. Findings revealed statistically significant positive relationships between agitation and severity of dementia (r = 0.34, P = 0.01), discomfort and severity of dementia (r = 0.44, P = 0.01), and agitation and discomfort (r = 0.50, P = 0.003). In a multiple regression analysis, agitation was significantly associated with discomfort (R(2) =.14, P = 0.02) after controlling for dementia severity. These preliminary findings suggest that discomfort may be a source of agitation.

Advancing the science of symptom management.

UNLABELLED: Since the publication of the original Symptom Management Model (Larson et al. 1994), faculty and students at the University of California, San Francisco (UCSF) School of Nursing Centre for System Management have tested this model in research studies and expanded the model through collegial discussions and seminars. AIM: In this paper, we describe the evidence-based revised conceptual model, the three dimensions of the model, and the areas where further research is needed. BACKGROUND/RATIONALE: The experience of symptoms, minor to severe, prompts millions of patients to visit their healthcare providers each year. Symptoms not only create distress, but also disrupt social functioning. The management of symptoms and their resulting outcomes often become the responsibility of the patient and his or her family members. Healthcare providers have difficulty developing symptom management strategies that can be applied across acute and home-care settings because few models of symptom management have been tested empirically. To date, the majority of research on symptoms was directed toward studying a single symptom, such as pain or fatigue, or toward evaluating associated symptoms, such as depression and sleep disturbance. While this approach has advanced our understanding of some symptoms, we offer a generic symptom management model to provide direction for selecting clinical interventions, informing research, and bridging an array of symptoms associated with a variety of diseases and conditions. Finally, a broadly-based symptom management model allows the integration of science from other fields.

Monitoring and improving pain management practices. A quality improvement approach.

The development of a multidisciplinary pain management committee is a critical step in monitoring and improving pain management practices. The systematic evaluation of the quality of pain management using the principles of QI establishes a process that can lead to improvements in the care that patients receive. Clinicians need to develop a 1- to 2-year plan to improve the quality of pain management. Changes in clinicians' behaviors occur slowly; thus, members of pain management committees should not become discouraged but continue to move forward one step at a time.

The PRO-SELF Program: a self-care intervention program for patients receiving cancer treatment.

OBJECTIVES: To describe the development, testing, and refinement of the PRO-SELF Program as used in randomized clinical trials. DATA SOURCES: Research studies and articles. CONCLUSIONS: The PRO-SELF Program has made an important contribution in enhancing patients' self-care and reducing morbidity. It has the potential to contribute to self-care abilities of children and adolescents who have cancer. IMPLICATIONS FOR NURSING PRACTICE: It is imperative that patients and their families have the essential information, skills, and support to carry out effective self-care symptom management.

Impact of cancer-related fatigue on the lives of patients: new findings from the Fatigue Coalition.

PURPOSE: This survey was designed to confirm the prevalence and duration of fatigue in the cancer population and to assess its physical, mental, social, and economic impacts on the lives of patients and caregivers. Patients and Methods. A 25-minute telephone interview was completed with 379 cancer patients having a prior history of chemotherapy. Patients were recruited from a sample of 6, 125 households in the United States identified as having a member with cancer. The median patient age was 62 years, and 79% of respondents were women. Patients reporting fatigue at least a few times a month were asked a series of questions to better describe their fatigue and its impact on quality of life. RESULTS: Seventy-six percent of patients experienced fatigue at least a few days each month during their most recent chemotherapy; 30% experienced fatigue on a daily basis. Ninety-one percent of those who experienced fatigue reported that it prevented a "normal" life, and 88% indicated that fatigue caused an alteration in their daily routine. Fatigue made it more difficult to participate in social activities and perform typical cognitive tasks. Of the 177 patients who were employed, 75% changed their employment status as a result of fatigue. Furthermore, 65% of patients indicated that their fatigue resulted in their caregivers taking at least one day (mean, 4.5 days) off work in a typical month. Physicians were the health care professionals most commonly consulted (79%) to discuss fatigue. Bed rest/ relaxation was the most common treatment recommendation (37%); 40% of patients were not offered any recommendations. CONCLUSIONS: Cancer-related fatigue is common among cancer patients who have received chemotherapy and results in substantial adverse physical, psychosocial, and economic consequences for both patients and caregivers. Given the impact of fatigue, treatment options should be routinely considered in the care of patients with cancer.
