Promulgation of guidelines for mucositis management: educating health care professionals and patients.

BACKGROUND: The Multinational Association for Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) Mucositis and Patient and Professional Education Study Groups are collaborating to improve the promulgation of the updated mucositis management guidelines. The initial step in the collaboration was to survey cancer care health professionals to determine their awareness of the original 2004 guidelines and their opinions on the usefulness of patient educational materials based on the guidelines. MATERIALS AND METHODS: The authors surveyed four samples (three US and one European) of cancer health care professionals attending three cancer-related professional conferences between May and July 2005 using a ten-item questionnaire in both paper-and-pencil and web-based formats. Data were compiled and analyzed using descriptive statistics. RESULTS: All respondents were generally aware of the importance of mucositis as a treatment-limiting toxicity with life-threatening complications and endorsed regular oral assessment and dental care practices. Only about one third of the US respondents were aware of the 2004 guidelines in contrast to 80% of the European respondents. A majority of respondents across all four surveys (66-93%) felt strongly that educational materials based on the guidelines were needed and that they would use them, while a smaller number (7-29%) indicated they might use them if a patient had a problem with mucositis. CONCLUSIONS: Awareness of the guidelines remains limited in the US, and use of the guidelines worldwide is minimal. The Mucositis and Patient and Professional Education Study Groups have developed a set of strategies to enhance dissemination, awareness, and use of the updated guidelines and to promote patient education based on the guidelines. Future work will focus on implementation and evaluation of the guidelines in clinical practice.

The role of basic oral care and good clinical practice principles in the management of oral mucositis.

BACKGROUND: The Basic Oral Care Group is one of eight subcommittees functioning within the Mucositis Study Group Guidelines Panel of the Multinational Association of Supportive Care in Cancer and International Society for Oral Oncology (MASCC/ISOO). The Basic Oral Care Group, comprised of the four authors of this paper, represented the disciplines of nursing (DBM, JJ), dentistry (MEPC), and pediatric dentistry (PW). This group reviewed research and clinical literature to update the original 2004 Mucositis Management Guidelines in the areas of basic oral care, bland rinses, protocols and education, and good clinical practices such as pain management, oral assessment, oral care, and dental care. MATERIALS AND METHODS: Over 100 articles published between 2000 and 2005 were identified, and 32 of these were useful for the analysis. Each article was rated by at least two authors using a structured rating form and systematic determination of levels of evidence, based on the American Society of Clinical Oncology criteria. Discussion at the 2005 MASCC/ISOO Geneva pre-conference meeting of the Guidelines Panel resulted in the development of consensus on the interpretation of the literature. RESULTS: Based on the literature and on Panel discussions, a revision of the original guidelines for protocols and education was produced by the group, and they developed a set of recommendations related to good clinical practices. CONCLUSIONS: Although research remains scanty for components of basic oral care, bland rinses, protocols, and education, the original 2004 guidelines with the help of newer literature from 2000 to 2005 and expert consensus among the Guidelines Panel enabled the development of useful clinical practice guidelines for managing oral mucositis in patients receiving cancer treatment with radiation and/or chemotherapy.

The cancer pain experience of Israeli adults 65 years and older: the influence of pain interference, symptom severity, and knowledge and attitudes on pain and pain control.

GOALS: Little is known about Israeli elders' cancer pain experience. The purpose of this study was to explore the cancer pain experience, including pain intensity, pain management index, pain interference, symptom severity, and knowledge and attitudes toward pain and pain control. PATIENTS AND METHODS: Descriptive cross-sectional methods were used to obtain data with four instruments. The patients were 39 Israelis 65 years and older who were receiving outpatient treatment for cancer in a major hospital center in Israel. RESULTS: Results showed that over half (56.7%) reported severe worst pain and had negative pain management indexes (56.4%). In addition, knowledge and attitudes toward pain and pain control were poor (54.55%). There were no significant relationships between pain intensity and other variables. However, pain interference demonstrated a significant positive relationship with symptom severity. Post hoc analysis revealed that Ashkenazi Jewish and more educated patients reported significantly less pain interference than Sephardic Jewish patients. CONCLUSION: Larger samples representative of the cultural differences in Israel are needed to more definitively identify elements of the cancer pain experience in Israeli elders that can be addressed to improve pain management.

Evidence-based guidelines for managing mucositis.

OBJECTIVES: To discuss implementation of evidence-based clinical practice guidelines for mucositis. DATA SOURCE: Published articles, book chapters, web sources, clinical experience, unpublished manuscripts. CONCLUSION: Nurses can implement evidence-based guidelines but must include an evaluation component to determine effect on clinical outcomes. IMPLICATIONS FOR NURSING PRACTICE: Nurses have an integral role implementing and evaluating evidence-based practice guidelines for managing mucositis. When evidence is lacking and guidelines have gaps, nurses can play important roles in research to overcome these gaps.

Occurrence of cancer pain.

Occurrence of cancer pain is highly variable and incompletely understood. Surveys are not population-based, are characterized by small heterogeneous samples, and provide sketchy data on etiology of pain, pain syndromes, and clinical or demographic factors. Moreover, the multiple dimensions of pain have not been thoroughly elucidated. Cancer-related pain is caused by the following: 1) direct tumor involvement, 2) diagnostic/therapeutic procedures, and 3) side effects or toxicities of treatment. Individuals may have more than one type of cancer-related pain simultaneously. Occurrence rates range from 14% to 100%, and between 33 and 50% of patients experience pain at some point in the cancer trajectory. Rates are higher (e.g., 70%-100%) in palliative care or pain management settings. Few researchers have focused solely on specific causes of pain in specific patient populations, and only a few included groups at higher risk for pain, such as the elderly or underserved. In general, researchers have not followed pain over time to determine its course, severity, effects on quality of life and functional status, and other related factors. Future researchers should aim to acquire specific information on occurrence of pain in a variety of cancer diagnoses, settings, and groups of people. Longitudinal designs, in-depth exploration of dimensions of pain, and delineation of specific issues in groups such as the elderly, children, and vulnerable populations are essential. Addressing these critical areas will improve our understanding of the occurrence and effects of pain and enhance our ability to provide appropriate interventions, thereby increasing patients' quality of life.

Barriers and strategies in implementation of oral care standards for cancer patients.

Oral complications of cancer therapy include mucositis, oral pain, poor oral intake, infection, bleeding, and difficulty communicating. Use of oral care standards can help manage these problems, but their systematic implementation is relatively rare. The purpose of this paper is to discuss barriers to implementing oral care standards, and to make suggestions for how such standards might be implemented in clinical settings. These purposes are accomplished through a review of relevant literature from various health-care disciplines, and discussion of one institution's implementation of an oral care standard for leukemia and bone marrow/stem cell transplant patients. Key principles underlying this successful institutional effort were recognition of the medical necessity of oral care, collaboration among health-care disciplines, and use of evidence-based practice wherever possible.

Gender differences in pain characteristics of chronic stable angina and perceived physical limitation in patients with coronary artery disease.

Chronic stable angina pectoris, the chest pain associated with reversible myocardial ischemia has detrimental effects on health-related quality of life, particularly in women. The limited research on gender differences in chronic stable angina suggests that angina may be experienced differently in women and that women report greater functional disability related to angina symptoms. No studies have examined gender differences in chronic stable angina from a multidimensional pain perspective or have included reliable and valid measures of pain that would facilitate comparing chronic angina patients with other chronic pain populations. The purpose of this descriptive study was to examine gender differences in characteristics of chronic stable angina using the short-form McGill pain questionnaire (SF-MPQ) and to explore relationships among these pain characteristics and perceived limitation in performing physical activities in patients with coronary artery disease (CAD) (physical limitation subscale of the Seattle angina questionnaire). One hundred and twenty-eight subjects (30.5% women) with stable CAD and angina pectoris documented by a cardiologist completed study questionnaires in an outpatient cardiology clinic. Results of the study suggest that men and women with chronic stable angina had more similarities than differences in chest pain characteristics. No significant gender differences were demonstrated in total sensory or affective intensity scores, the present pain intensity index, or the number of pain words chosen. However, women did report significantly greater pain intensity on the SF-MPQ visual analogue scale. Women were also significantly more likely to describe their chronic angina as 'hot-burning' and 'tender' and to have greater intensity of pain for these two descriptors. Despite the similarities in pain characteristics, women reported greater physical limitation related to anginal pain. The variables of social status and years diagnosed with CAD significantly interacted with gender in predicting physical limitation suggesting that gender-specific models of physical limitation in angina patients need to be explored. To our knowledge, this is one of the first studies that has assessed chronic anginal pain using a reliable and valid generic pain instrument. More research is needed to better understand the nature of gender differences in functional limitation secondary to anginal pain and the physiologic, cognitive-perceptual and psychosocial mechanisms that lead to angina-related functional disability.

Defining clinically meaningful outcomes in the evaluation of new treatments for oral mucositis: oral mucositis patient provider advisory board.

Oral mucositis (OM)-related outcomes constituting a meaningful clinical advance in bone marrow transplant patients were considered by an interdisciplinary panel. Meaningful outcomes are essential in product development for OM, a condition without effective prevention or treatment. The most important outcomes to measure, the feasibility of measuring these in a clinical trial, and clinically meaningful differences in these outcomes were determined by the panel. Most important are reduction in oral pain and use of opioid analgesics, improvement in oral intake and quality of life, and reduction of hospitalization duration. Reduction in the severity of OM measured by an objective evaluation of oral mucosa could provide insight regarding the biologic activity of an intervention. Further data are required to define the precise relationship between reduction in visible OM and improvement in outcome. Minimally, clinical trials for OM should assess oral pain, opioid use, oral intake, and include objective assessment of OM.

The 20 item oral mucositis index: reliability and validity in bone marrow and stem cell transplant patients.

Precise quantification of oral complications in cancer patients receiving bone marrow and stem cell transplantation is essential when testing new treatment strategies for mucositis. Using 133 adult transplant patients, the authors evaluated the 20 item oral mucositis index (OMI), adapted from the 34 item OMI, to facilitate use by nondental health professionals. The OMI-20 consists of nine items measuring erythema, nine measuring ulceration, one measuring atrophy, and one measuring edema; all are scored from 0 = none to 3 = severe and summed for a total possible score of 0-60. The two sets of nine items measuring erythema and ulceration can also be summed separately to produce subscale scores ranging from 0 to 27. Results demonstrated internal consistency, test-retest, and inter-rater reliability, and strong evidence of construct validity. Provided that clinical examiners have appropriate training and experience, the OMI-20 can be used as a reliable, valid, and quantifiable measure of mucositis in clinical research.

Mucosal tissue injury in cancer therapy. More than muscositis and mouthwash.

PURPOSE: The purpose of this article is as follows: 1) to describe the characteristics and scope of mucosal tissue injury associated with cancer treatment; 2) to discuss recent advances in related basic and clinical science; and 3) to articulate research needs and opportunities to be addressed through collaborative interdisciplinary research. OVERVIEW: Mucosal tissue injury is both a direct and indirect consequence of cancer therapy, with manifestations that include damage and a number of other potentially serious sequelae. Current research in mucosal tissue injury is focused on the biology, immunology, and genetics of mucosal injury; clinical problems; assessment and management; and processes and outcomes of care. CLINICAL IMPLICATIONS: Results from these various areas of research enhance the understanding of the mechanisms of mucosal tissue injury, provide direction for the development of policy and for clinical practice, and help to define research needs and opportunities. Future research on the complex process of mucosal tissue injury will be interdisciplinary and will cross the boundaries among basic, translational, and clinical science.

Symptom clusters: concept analysis and clinical implications for cancer nursing.

The purpose of this article is to analyze the concept of symptom clusters and to discuss its application to cancer nursing to promote communication and enhance scientific knowledge. Rodgers' evolutionary method of concept analysis served as the framework for reviewing literature from psychology/psychiatry, general medicine, and nursing. Attributes of symptom clusters were relationships of symptoms and relationships of clusters, concurrence, underlying dimensions, stability, and common etiology. The major antecedent was the presence of 2 or more symptoms. Consequences were poorer physical health status, interference with activities of daily living, emotional distress, and increased financial burden. A symptom cluster is defined as consisting of 2 or more symptoms that are related to each other and that occur together. Symptom clusters are composed of stable groups of symptoms, are relatively independent of other clusters, and may reveal specific underlying dimensions of symptoms. Relationships among symptoms within a cluster should be stronger than relationships among symptoms across different clusters. Symptoms in a cluster may or may not share the same etiology. Symptom should be broadened to include both subjective (self-reported) symptoms and objective (observed) signs. Implications for researchers include the need to use a clear definition, determine the optimal methods of identifying etiology and nature of symptom clusters in various populations, assess the clinical utility of symptom clusters, and test interventions. Implications for practitioners include the need to comprehensively assess symptoms over the entire cancer trajectory, select interventions that target single and multiple symptoms, and evaluate outcomes that include quality of life and economic variables.

The Seattle angina questionnaire: reliability and validity in women with chronic stable angina.

Angina pectoris causes substantial psychological and functional disability and adversely effects health-related quality of life, particularly in women. Studies of cardiac disease-specific quality of life in women with coronary artery disease and angina are limited because little reliability and validity data for these instruments exist for women. Therefore, the purpose of this study was to examine reliability and validity of the Seattle Angina Questionnaire (SAQ), a cardiac disease-related quality-of-life measure, in a sample of women with chronic stable angina. A secondary analysis was performed on SAQ data from 175 women with a confirmed diagnosis of CAD and angina pectoris. The majority of the women were older, white, living with their spouse, had a previous acute myocardial infarction, and had undergone revascularization. The Cronbach alpha was used to assess reliability of the SAQ's five subscales, and factor analysis was used to assess the SAQ's validity. Results suggest that the SAQ is a reliable and valid quality-of-life measure in women with CAD. The physical limitations subscale factored into two separate factors, suggesting that the subscale measures two domains of physical function: self-care and exercise tolerance/mobility. Future research is needed to determine whether examining different combinations of SAQ items might provide a more sensitive assessment of cardiac disease-specific quality of life in women.
