Contribution of Clostridium difficile infection to the development of lower gastrointestinal adverse events during autologous stem cell transplantation.

BACKGROUND: Lower gastrointestinal (GI) adverse events (LGAE) are common afflictions of patients undergoing stem cell transplantation (SCT). Unfortunately, the pathophysiology remains poorly characterized. Emerging data suggest a prominent role of intestinal microbiota; however, contributions of pathogenic gut microbiota such as Clostridium difficile are not well defined. We performed a genome-wide association study (GWAS) to investigate clinical and genetic factors associated with development of LGAE. METHODS: A total of 972 patients undergoing autologous SCT were graded for LGAE based on Common Terminology Criteria for Adverse Events (v 4.0). Germline DNA material was obtained from leukapharesis products and genotyped using Illumina(®) Whole Genome Genotyping Infinium chemistry and HumanOmni1-Quad Bead chips containing over 1.1 million single nucleotide polymorphisms (SNPs) (Illumina, San Diego, California, USA). Statistical models incorporating clinical factors, genetic factors, and a combination of clinical plus genetic factors were utilized to compare patients who developed severe LGAE (grade 2 or above) and others. RESULTS: Among 972 patients, 459 (47.2%) developed severe LGAE. Baseline hemoglobin and hematocrit, estimated glomerular filtration rate, ß2-microglobulin, protocol type, and C. difficile infection (CDI) were associated with severe LGAE on univariate analysis, Genomic comparisons between groups did not reveal any SNPs associated with severe LGAE and neither did incorporation of genetic factors into the clinical model. In addition, 11 candidate SNPs associated with upper GI mucositis were evaluated, alongside clinical factors in a multivariate model. Only CDI was found to be associated with severe LGAE in all models. CONCLUSION: CDI is a prominent factor in the development of LGAE in patients undergoing autologous SCT.

Individual pulmonary vein size and survival in infants with totally anomalous pulmonary venous connection.

OBJECTIVES: We investigated whether mortality in totally anomalous pulmonary venous connection could be predicted from preoperative individual pulmonary vein size. BACKGROUND: Some infants with this anomaly die with or without surgical repair because of stenosis of individual pulmonary veins. METHODS: Individual pulmonary vein, vertical vein and pulmonary venous confluence diameters were retrospectively measured from preoperative echocardiograms in 32 infants with totally anomalous pulmonary venous connection presenting to Children's Hospital, Boston over a 4 1/2-year period. Data on body surface area, other cardiac anomalies, presence of initial pulmonary venous obstruction and early surgery and outcome were also recorded. RESULTS: Of 32 patients, 6 (18.8%) died before hospital discharge, and 8 (25.0%) died subsequently. Six (75.0%) of the eight patients who died late had individual pulmonary vein stenosis at sites remote from the surgical anastomosis to the left atrium. The remaining 18 patients (56.3%) are alive at a mean follow-up period of 9.7 months. A Cox proportional hazards model revealed that small sum of individual pulmonary vein diameters (p = 0.0004), small confluence size (p = 0.02) and presence of heterotaxy syndrome (p = 0.008) were each significant univariate predictors of survival. Multivariate analysis showed that small pulmonary vein sum was a strong predictor of survival (p = 0.008), independent of the presence of heterotaxy syndrome. An analysis stratified by the presence of heterotaxy syndrome showed that the predictive effect of small pulmonary vein sum on survival was strongest in patients without heterotaxy syndrome. CONCLUSIONS: These data show that individual pulmonary vein size at diagnosis is a strong, independent predictor of survival in patients with totally anomalous pulmonary venous connection. In patients with this anomaly and small individual pulmonary veins, the anomaly may not be correctable by surgical creation of an anastomosis between the pulmonary venous confluence and the left atrium.

Chronic care clinics for diabetes in primary care: a system-wide randomized trial.

OBJECTIVE: To evaluate the impact of primary care group visits (chronic care clinics) on the process and outcome of care for diabetic patients. RESEARCH DESIGN AND METHODS: We evaluated the intervention in primary care practices randomized to intervention and control groups in a large-staff model health maintenance organization (HMO). Patients included diabetic patients > or = 30 years of age in each participating primary care practice, selected at random from an automated diabetes registry. Primary care practices were randomized within clinics to either a chronic care clinic (intervention) group or a usual care (control) group. The intervention group conducted periodic one-half day chronic care clinics for groups of approximately 8 diabetic patients in their respective doctor's practice. Chronic care clinics consisted of standardized assessments; visits with the primary care physician, nurse, and clinical pharmacist; and a group education/peer support meeting. We collected self-report questionnaires from patients and data from administrative systems. The questionnaires were mailed, and telephoned interviews were conducted for nonrespondents, at baseline and at 12 and 24 months; we queried the process of care received, the satisfaction with care, and the health status of each patient. Serum cholesterol and HbA1c levels and health care use and cost data was collected from HMO administrative systems. RESULTS: In an intention-to-treat analysis at 24 months, the intervention group had received significantly more recommended preventive procedures and helpful patient education. Of five primary health status indicators examined, two (SF-36 general health and bed disability days) were significantly better in the intervention group. Compared with control patients, intervention patients had slightly more primary care visits, but significantly fewer specialty and emergency room visits. Among intervention participants, we found consistently positive associations between the number of chronic care clinics attended and a number of outcomes, including patient satisfaction and HbA1c levels. CONCLUSIONS: Periodic primary care sessions organized to meet the complex needs of diabetic patients imrproved the process of diabetes care and were associated with better outcomes.

Subjective memory complaints prior to and following electroconvulsive therapy.

Using the Squire Subjective Memory Questionnaire (SSMQ), depressed patients rated their memory functioning prior to a course of brief pulse, electroconvulsive therapy (ECT) within the 1 week following the course and 2 months later. Normal controls made similar ratings at comparable intervals. Prior to ECT, patients reported poorer memory functioning than controls. There was marked improvements in the patients' self-reports shortly following ECT, and at 2-month follow-up SSMQ scores were generally comparable in patients and controls. At all time points, the severity of depressive symptoms was strongly associated with patients' reports of memory dysfunction. SSMQ subscales ("depression" and "ECT" items) were not differentially sensitive to effects of ECT or depression. Relations between ECT treatment parameters and changes in patients' self-evaluations only emerged after controlling for clinical state change. Shortly following ECT, there were no relations between SSMQ scores and objective measures of cognitive functioning. However, 2 months following ECT, there was a suggestion that greater retrograde amnesia for autobiographical memories was associated with self-rating of greater memory impairment.

Amphetamine disrupts P50 suppression in normal subjects.

BACKGROUND: P50 suppression is viewed as an operational measure of sensory "gating" that is reduced in patients with schizophrenia and their family members. Previous reports have demonstrated that neural gating is regulated by monoaminergic tone in rodent models of P50 suppression. METHODS: In this study, 11 healthy subjects participated in P50 event-related potential recordings at baseline and after either oral administration of dextroamphetamine (.3 mg/kg) or placebo, to determine if the administration of a monoaminergic agonist produces P50 suppression deficits similar to those observed in patients with schizophrenia. RESULTS: As hypothesized, amphetamine disrupted the suppression of the P50 event-related potential. There was a statistically significant decrement in P50 suppression during the amphetamine challenge condition (t10 = 3.15, p < .01, mean difference = -44.1%, d = -2.5) relative to the baseline P50 condition. A comparison of P50 suppression in the placebo and amphetamine conditions (both after a baseline recording session) revealed a significant amphetamine-induced disruption of P50 suppression (t6 = 3.71, p < .01, mean difference = -54.4%, d = -3.14). CONCLUSIONS: The biochemical alterations associated with an amphetamine-induced disruption of P50 suppression in this study may be related to the pathophysiology of P50 suppression deficits in schizophrenia. The findings are consistent with several careful examinations of suppression deficits in rodent models that have identified the monoaminergic regulation of P50 suppression. These data indicate that amphetamine induces a disruption of P50 suppression in normal subjects.

Breast cancer screening programmes in 22 countries: current policies, administration and guidelines. International Breast Cancer Screening Network (IBSN) and the European Network of Pilot Projects for Breast Cancer Screening.

BACKGROUND: Currently there are at least 22 countries worldwide where national, regional or pilot population-based breast cancer screening programmes have been established. A collaborative effort has been undertaken by the International Breast Cancer Screening Network (IBSN), an international voluntary collaborative effort administered from the National Cancer Institute in the US for the purposes of producing international data on the policies, funding and administration, and results of population-based breast cancer screening. METHODS: Two surveys conducted by the IBSN in 1990 and 1995 describe the status of population-based breast cancer screening in countries which had or planned to establish breast cancer screening programmes in their countries. The 1990 survey was sent to ten countries in the IBSN and was completed by nine countries. The 1995 survey was sent to and completed by the 13 countries in the organization at that time and an additional nine countries in the European Network. RESULTS: The programmes vary in how they have been organized and have changed from 1990 to 1995. The most notable change is the increase in the number of countries that have established or plan to establish organized breast cancer screening programmes. A second major change is in guidelines for the lower age limit for mammography screening and the use of the clinical breast examination and breast self-examination as additional detection methods. CONCLUSION: As high quality population-based breast cancer screening programmes are implemented in more countries, they will offer an unprecedented opportunity to assess the level of coverage of the population for initial and repeat screening, evaluation of performance, and, in the longer term, outcome of screening in terms of reduction in the incidence of late-stage disease and in mortality.

Hospitalization rates in nursing home residents with dementia. A pilot study of the impact of a special care unit.

Although Special Care Units (SCUs) have recently gained attention as appropriate places for caring for institutionalized patients with dementia, few studies have evaluated their effectiveness. This pilot study focused primarily on one aspect of patient care, the possible prevention of acute hospitalization. Because transfer from nursing home to the acute hospital can be a traumatic experience for patients with dementia, important services that SCUs might provide include those preventive strategies aimed at reducing the need for transfer to the acute hospital. Medical record abstraction revealed that over one year, the rate of acute hospitalization was 21% among 47 patients with dementia in SCUs, compared with 14% among 36 patients with dementia and 14% among 22 patients with no listed diagnosis of dementia residing in non-SCU settings within the same facility. Thus, no statistically significant difference in hospitalization rates was found, although the trend was for increased hospitalization for SCU patients. There was a trend toward deterioration in functional status among SCU patients following first hospitalization (P less than .10). Since the majority of these patients were hospitalized for hip fractures, this finding was not unexpected. There was a trend toward cognitive decline after hospitalization among patients with dementia who were not residing in an SCU (P less than .10). In order to investigate whether acute hospitalizations among SCU patients were preventable, an expert panel was convened to review each episode of illness leading to acute hospitalization. Of the 15 hospitalizations, none were judged "preventable," four were believed to be "possibly preventable," and 11 were considered to have been "not preventable."(ABSTRACT TRUNCATED AT 250 WORDS)

Chronic care clinics: a randomized controlled trial of a new model of primary care for frail older adults.

OBJECTIVE: To determine whether a new model of primary care, Chronic Care Clinics, can improve outcomes of common geriatric syndromes (urinary incontinence, falls, depressive symptoms, high risk medications, functional impairment) in frail older adults. DESIGN: Randomized controlled trial with 24 months of follow-up. Physician practices were randomized either to the Chronic Care Clinics intervention or to usual care. SETTING: Nine primary care physician practices that comprise an ambulatory clinic in a large staff-model HMO in western Washington State. PARTICIPANTS: Those patients aged 65 and older in each practice with the highest risk for being hospitalized or experiencing functional decline. INTERVENTION: Intervention practices (5 physicians, 96 patients) held half-day Chronic Care Clinics every 3 to 4 months. These clinics included an extended visit with the physician and nurse dedicated to planning chronic disease management; a pharmacist visit that emphasized reduction of polypharmacy and high-risk medications; and a patient self-management/support group. Control practices (4 physicians, 73 patients) received usual care. MEASUREMENTS: Changes in self-reported urinary incontinence, frequency of falls, depressive symptoms, physical function, and satisfaction were analyzed using an intention-to-treat analysis adjusted for baseline differences, covariates, and practice-level variation. Prescriptions for high-risk medications and cost/utilization data obtained from administrative data were similarly analyzed. RESULTS: After 24 months, no significant improvements in frequency of incontinence, proportion with falls, depression scores, physical function scores, or prescriptions for high risk medications were demonstrated. Costs of medical care including frequency of hospitalization, hospital days, emergency and ambulatory visits, and total costs of care were not significantly different between intervention and control groups. A higher proportion of intervention patients rated the overall quality of their medical care as excellent compared with control patients (40.0% vs 25.3%, P = .10). CONCLUSIONS: Although intervention patients expressed high levels of satisfaction with Chronic Care Clinics, improved outcomes for selected geriatric syndromes were not demonstrated. These findings suggest the need for developing greater system-wide support for managing geriatric syndromes in primary care and illustrate the challenges of conducting practice improvement research in a rapidly changing delivery system.

The relationship of joint symptoms with exercise performance in older adults.

OBJECTIVES: The objective of this study is to determine if exercise increases joint symptoms in older adults with a history of arthritis or produces symptoms in older adults without such history. In addition, we examine whether joint symptoms explain the large observed variation in strength gain in older adults undergoing vigorous strength training exercise, and report the incidence of musculoskeletal injuries upon initiation of an exercise program. DESIGN: A population-based, single blinded, randomized controlled trial with three exercise groups and one control group. SETTING: A large urban health maintenance organization. PARTICIPANTS: Older men and women (N = 105) aged 68 to 85, with leg strength below the 50th percentile for their age, sex, height, and weight and without neuromuscular disease or active cardiovascular disease. INTERVENTIONS: Supervised exercise in 1-hour sessions, three times each week, for 24 to 26 weeks. One exercise group did strength training (ST) using weight machines (n = 25); another group did endurance training (ET) using stationary cycles (n = 25); and the third group did combined strength training and endurance training (ST+ET) (n = 25). The control group (n = 30) received no intervention. MEASUREMENTS: Strength was measured at the ankle, knee, hip, and elbow using an isokinetic dynamometer. Joint symptoms were rated on a 6-point scale (0 = none, 5 = severe). Arthritis severity was based on self-reported use of arthritis medication. Health status was measured with subscales of the SF-36 and Sickness Impact Profile (SIP). RESULTS: Joint symptoms fluctuated over time in all exercise groups, but they did not improve or worsen significantly in any group. The physical dimension of the SIP and SF-36 subscale scores, including Bodily Pain Scores, did not change over time in any group. Subjects with arthritis and joint symptoms gained as much strength with strength training as did subjects without joint symptoms. Adjustment for age, gender, baseline strength, adherence, and exercise group did not affect this finding. The rate of minor musculoskeletal injuries was 2.2 injuries per 1000 exercise hours. CONCLUSIONS: Moderate intensity stationary cycle exercise and vigorous intensity strength training do not appear to produce or exacerbate joint symptoms in older adults. Joint symptoms did not explain the large variation in gains in strength in older adults participating in a standardized strength training exercise program. Musculoskeletal injuries occurred relatively infrequently, and no major injuries occurred. In evaluating joint pain that occurs in older adults in well regulated exercise programs, clinicians should consider other etiologies before attributing pain to exercise per se.

Predicting hospitalization and functional decline in older health plan enrollees: are administrative data as accurate as self-report?

OBJECTIVE: To compare the predictive accuracy of two validated indices, one that uses self-reported variables and a second that uses variables derived from administrative data sources, to predict future hospitalization. To compare the predictive accuracy of these same two indices for predicting future functional decline. DESIGN: A longitudinal cohort study with 4 years of follow-up. SETTING: A large staff model HMO in western Washington State. PARTICIPANTS: HMO Enrollees 65 years and older (n = 2174) selected at random to participate in a health promotion trial and who completed a baseline questionnaire. MEASUREMENT: Predicted probabilities from the two indices were determined for study participants for each of two outcomes: hospitalization two or more times in 4 years and functional decline in 4 years, measured by Restricted Activity Days. The two indices included similar demographic characteristics, diagnoses, and utilization predictors. The probabilities from each index were entered into a Receiver Operating Characteristic (ROC) curve program to obtain the Area Under the Curve (AUC) for comparison of predictive accuracy. RESULTS: For hospitalization, the AUC of the self-report and administrative indices were .696 and .694, respectively (difference between curves, P = .828). For functional decline, the AUC of the two indices were .714 and .691, respectively (difference between curves, P = .144). CONCLUSIONS: Compared with a self-report index, the administrative index affords wider population coverage, freedom from nonresponse bias, lower cost, and similar predictive accuracy. A screening strategy utilizing administrative data sources may thus prove more valuable for identifying high risk older health plan enrollees for population-based interventions designed to improve their health status.

Recruiting African-American older adults for a community-based health promotion intervention: which strategies are effective?

INTRODUCTION: The purpose of this article is to examine the effectiveness of recruitment strategies used to recruit African-American older adults for a senior center-based health promotion trial with a 6-month exercise component. METHODS: We compared multiple strategies for recruiting participants from senior center members and other older adults residing in the surrounding predominantly African-American community. The phonathon, direct telephone recruitment by senior center leadership, is compared with traditional approaches. RESULTS: All recruiting strategies combined yielded a total of 120 participants. Phonathons involving five or six senior center board members in two half-day sessions yielded 40 participants or 33% of all participants. Strategies categorized as printed media yielded 39 participants or 33% of all participants. Strategies categorized as word-of-mouth yielded 31 participants or 26% of all participants. Remaining approaches accounted for an additional 10 participants or 8% of all participants. CONCLUSIONS: Our results support employing a multifaceted recruitment approach and demonstrate the importance of strong linkages between the research team and community leaders in conducting health promotion research in minority communities. An innovative approach, the phonathon, may be a potentially important recruitment strategy.

Breast cancer screening in 21 countries: delivery of services, notification of results and outcomes ascertainment.

Following clinical trial evidence of mammography screening's efficacy and effectiveness, data are needed from organized population-based programmes to determine whether screening in these programmes results in breast cancer mortality reductions comparable to those demonstrated in controlled settings. The International Breast Cancer Screening Network (IBSN) conducted two international programme assessments: in 1990 among nine countries and in 1995 among 22 countries, obtaining information on the organization and process for screening within breast cancer screening programmes. This manuscript describes procedures for recruitment, service delivery, interpretation and communication of results, case ascertainment, and quality assurance. Practices in more established programmes are compared with pilot programmes. Each IBSN country defined a unique programme of population-based breast cancer screening. Some programmes were sub-national rather than national in scope, while others were in pilot stages of development. Screening took place in dedicated centres in established programmes and in both dedicated and general radiology centres in pilot programmes. Although most countries used personal invitation systems to recruit women to screening, other recruitment mechanisms were used. Most countries used two-view mammography in their screening programmes. About half had implemented independent double reading of mammograms, considering it a key component of high-quality mammography screening. In conclusion, diversity exists in the organization and delivery of screening mammography internationally. Quality assurance activities are a priority and are being evaluated in the IBSN.

Stroke rehabilitation in nursing homes: how do we measure quality?

Over one-third of Medicare stroke patients are admitted to nursing homes for rehabilitation. Patients with stroke who are admitted to nursing homes are extremely heterogeneous, including both those with minimal physical and cognitive impairment and those who are totally physically dependent. Quality measures that are appropriate for evaluating stroke care in nursing homes include outcome measures, particularly those that are patient-centered, such as self-reported functional recovery and return to the community; process measures involving essential services such as screening for depression and pain; and structural measures such as the availability of a psychologist or presence of an interdisciplinary team. In measuring quality, nursing home professionals must allow sufficient time for outcomes to unfold, such as 3 to 6 months, rather than measuring outcome at discharge from a setting. Nursing home professionals must also take into consideration patient heterogeneity in terms of risk factors for outcomes of interest.

Measuring breast self-examination proficiency. A scoring system developed from a paired comparison study.

A continuous scoring strategy yielding a proficiency score on breast self-examination (BSE) performance was developed and validated. The method of paired comparisons was used to provide a rank ordering on an interval scale of the eight components of the evaluation tool. Twenty-one experts in teaching the MammaCare method of breast self-examination participated in the survey to help in developing the composite measure of proficiency in BSE performance. Data on each component of BSE were collected quantitatively, and performance scores were computed using a formula incorporating the weighting schema derived from the paired comparisons procedure. A comparison of preteaching versus postteaching mean performance scores on BSE indicated that the scoring system worked even when the teaching method varied. The scoring system presented here is a start on the development of a tool that can be useful to researchers using relative performance as a measure in BSE studies. The components of the scoring system can be used by nurses in the practice setting as a checklist for evaluating BSE performance.

A statewide breast cancer screening project.

The cause of breast cancer remains unknown. Because prevention is not an option, early detection is the most viable alternative for decreasing the mortality rates from breast cancer. To promote early detection, the Arkansas Division of the American Cancer Society implemented a project aimed at increasing public awareness. The project used a three-pronged approach: the life-saving benefits of mammography, regular breast examination by a health-care professional, and the importance of regular breast self-examination (BSE). This article focuses on the third prong, BSE. Project members recruited and trained 408 BSE instructors in the MammaCare method of BSE and contacted a total of 87,141 Arkansas women about breast cancer and the importance of early detection. In a follow-up survey of 1,300 women, of the 198 (15%) who returned the surveys, two women reported finding lumps that were diagnosed as cancer.

Efficacy of breast self-examination teaching methods among older women.

Existing breast self-examination (BSE) educational approaches have not been successful in gaining older women's compliance in proficient BSE. The experimental study detailed in this article was designed to determine whether there is a difference in BSE performance between women taught BSE individually using self-modeling in addition to a breast model (experimental group) and women taught BSE in a group using only a breast model (control group). Seventy-nine women, age 50 and older, randomly were assigned to the experimental and the control group. A pretest, a post-test immediately after the instruction, and a second post-test three months later involved BSE specialists observing each woman performing examinations on her own breast and on a breast model. A paired comparisons study yielded a set of weights that was used in calculating performance scores. Repeated measures analysis indicated that women in the experimental group performed BSE significantly more proficiently than women in the control group (F = 3.27, df = 2, 140, p = 0.041).

Impact of silicone implants on the lives of women with breast cancer.

PURPOSE/OBJECTIVES: To describe the impact of silicone implants on the lives of women with breast cancer. DESIGN: Qualitative analysis of telephone interview data. SAMPLE: 120 women from across the United States who have reported to the Food and Drug Administration problems with breast implants following mastectomies. METHODS: Telephone interviews were used to gather responses to 110 questions. Qualitative analysis of narrative data was linked with quantitative data. MAIN RESEARCH VARIABLES: Concerns and feelings about breast implants; potential problems with silicone implants; source of information about problems; how they coped with the silicone implant controversy; problems related to their breast implants; the effect of health problems on day-to-day activities, relationships with significant others, work, and any other important aspects of their lives; and advice they would give other women regarding breast implant surgery. By linking the qualitative analysis of narrative data with quantitative data, the investigators sought to answer the following research question: Do the patterns of responses differ based on specific systemic physical problems, reported localized breast problems, or implant problems? FINDINGS: The women reported poorer quality of life and feelings of worry and anger because of health problems. They perceived they had received incomplete information and often had complaints dismissed by their healthcare providers. Most of them would not recommend silicone implants for patients undergoing mastectomy. The women's levels of satisfaction were directly associated with their feelings of being informed and the type of health problems they experienced. CONCLUSIONS: Women need reconstruction options following mastectomy, however, use of silicone implants can result in additional health problems and decreased quality of life as a result of those problems. IMPLICATIONS FOR NURSING PRACTICE: Nurses can assume the role of breast health educator, which includes counseling women with breast cancer about breast implants and other reconstructive options. Study results will help health providers care both for those patients considering treatment options and those coping with the problems and concerns related to their breast implants. Women should be told the inherent risks and complications associated with breast implants and also told when "we don't know."

A national survey of certified, recertified, and noncertified oncology nurses: comparisons and contrasts.

PURPOSE/OBJECTIVES: To explore opinions about the OCN credential, the ways in which it was obtained and retained, and the extent to which it is valued by employers. DESIGN: A descriptive comparison study using a cross-sectional survey design. SAMPLE: Questionnaires were mailed to a nationwide sample of 2,429 RN members of the Oncology Nursing Society; 1,217 (50%) surveys were returned. The majority of respondents were female, 30-49 years of age. Caucasian, and had practiced nursing for more than 11 years. MAIN RESEARCH VARIABLES: Certification status, work role characteristics, preparation strategies for the certification examination, and motivation for obtaining certification. FINDINGS: Oncology nurses recognize the importance and value of OCN certification. The primary reasons oncology nurses obtain and retain certification include the desire for personal achievement, professional growth, and development. OCNs were more likely to work in a setting where the employer supports professional development through continuing nursing education. IMPLICATIONS FOR NURSING PRACTICE: Because health care is increasingly delivered in ambulatory/home settings and the population is aging, oncology certification needs to be encouraged among nurses who work in these settings or with geriatric populations. Certified nurses tended to experience more job satisfaction than noncertified nurses.

Relationships between certification and job perceptions of oncology nurses.

PURPOSE/OBJECTIVES: To explore relationships between oncology nursing certification and oncology nurses' job perceptions. DESIGN: Descriptive, correlational. SETTING: Questionnaire mailed to homes of Oncology Nursing Society (ONS) members. SAMPLE: 703 certified and 514 noncertified ONS members (N = 1,217; 50% response rate). METHODS: Data were collected using survey methods and grouped by respondents' certification status for statistical analysis. MAIN RESEARCH VARIABLES: Certification, group cohesion, organizational commitment, and job satisfaction. FINDINGS: Certification was weakly correlated with cohesion, commitment, and satisfaction. Work setting, rather than certification, accounted for differences in job perceptions. Job perceptions were most positive in settings characterized by a high percentage of patients with cancer (> 75%), a high percentage of RNs (> or = 80%), and monetary support for continuing education. CONCLUSIONS: The hypothesis that oncology nurses' certification status is associated with job perceptions that are valued by employers was not supported. IMPLICATIONS FOR NURSING PRACTICE: Nurses' job perceptions have been linked to control over nursing practice and participation in organizational and clinical decision making. Managerial strategies that empower certified nurses to practice with more autonomy and participate in decisions that affect patient care should be emphasized.

Chemotherapy for glioblastoma multiforme.

Treatment for the patient with a glioblastoma multiforme often includes chemotherapy with many specific nursing implications directly associated with this form of treatment. While the four agents described share some common adverse effects such as nausea and vomiting, even with this relatively common adverse effect, the onset, duration and severity varies. Multiple other adverse effects like nephrotoxicity, ototoxicity, thrombocytopenia and leukocytopenia vary greatly from agent to agent in occurrence and severity. Knowing the mode of action for each agent, which adverse effects to expect, when to expect them and appropriate treatment measures will help the nurse, patient and family to better manage these effects and improve quality of life.
