Abstract

Background: Preventing the onset of injecting drug use is an important public health objective yet there is little understanding of the process that leads to injection initiation. This paper draws extensively on narrative data to describe how injection initiation is influenced by social environment. We examine how watching other people inject can habitualise non-injectors to administering drugs with a needle and consider the process by which the stigma of injecting is replaced with curiosity. Method: In-depth interviews (n = 54) were conducted as part of a 2-year longitudinal study examining the behaviours of new injecting drug users. Results: Among our sample, injection initiation was the result of a dynamic process during which administering drugs with a needle became acceptable or even appealing. Most often, this occurred as a result of spending time with current injectors in a social context and the majority of this study's participants were given their first shot by a friend or sexual partner. Initiates could be tenacious in their efforts to acquire an injection trainer and findings suggest that once injecting had been introduced to a drug-using network, it was likely to spread throughout the group. Conclusion: Injection initiation should be viewed as a communicable process. New injectors are unlikely to have experienced the negative effects of injecting and may facilitate the initiation of their drug-using friends. Prevention messages should therefore aim to find innovative ways of targeting beginning injectors and present a realistic appraisal of the long-term consequences of injecting. Interventionists should also work with current injectors to develop strategies to refuse requests from non-injectors for their help to initiate.

Abstract

Background: Studies have linked nurse staffing levels (number and skill mix) to several nurse-sensitive patient outcomes. However, evidence from European countries has been limited. Objectives: This study examines the association between nurse staffing levels (i.e. acuity-adjusted Nursing Hours per Patient Day, the proportion of registered nurses with a Bachelor's degree) and 10 different patient outcomes potentially sensitive to nursing care. Design-setting-participants: Cross-sectional analyses of linked data from the Belgian Nursing Minimum Dataset (general acute care and intensive care nursing units: n = 1403) and Belgian Hospital Discharge Dataset (general, orthopedic and vascular surgery patients: n = 260,923) of the year 2003 from all acute hospitals (n = 115). Methods: Logistic regression analyses, estimated by using a Generalized Estimation Equation Model, were used to study the association between nurse staffing and patient outcomes. Results: The mean acuity-adjusted Nursing Hours per Patient Day in Belgian hospitals was 2.62 (S.D. = 0.29). The variability in patient outcome rates between hospitals is considerable. The inter-quartile ranges for the 10 patient outcomes go from 0.35 for Deep Venous Thrombosis to 3.77 for failure-to-rescue. No significant association was found between the acuity-adjusted Nursing Hours per Patient Day, proportion of registered nurses with a Bachelor's degree and the selected patient outcomes. Conclusion: The absence of associations between hospital-level nurse staffing measures and patient outcomes should not be inferred as implying that nurse staffing does not have an impact on patient outcomes in Belgian hospitals. To better understand the dynamics of the nurse staffing and patient outcomes relationship in acute hospitals, further analyses (i.e. nursing unit level analyses) of these and other outcomes are recommended, in addition to inclusion of other study variables, including data about nursing practice environments in hospitals.

Abstract

The purpose of this analysis is to describe the attrition process from application to associate and baccalaureate basic RN programs through the first 2 years of work using estimates from best available nationally representative data. Results of the analysis show that although about 41,000 qualified applicants are not admitted to basic RN programs, most students (76.2%) who enroll in basic RN programs graduate, and most RN graduates who pass the National Council Licensure Examination stay in their first nursing job (73.8%) and nursing (97.9%) for at least 2 years. The results suggest that room for improvement exists for retention across educational and work settings, but the system appears to be most leaky at the point of admitting qualified applicants. Precise data about attrition from educational and employment settings are essential for resolving educational capacity and workforce retention issues, but precise data are difficult to obtain. A solution may be to assign each applicant a unique identifier.

Abstract

In light of evidence linking registered nurse (RN) staffing levels to patient outcomes in chronic hemodialysis facilities, U.S. government regulations have set minimum RN staffing requirements during dialysis. Consequently, facility administrators are focused on decreasing nurse attrition in this crucial practice setting. This study used a cross-sectional, correlational design to investigate the effects of workload, practice environment, and care processes on burnout among nurses in U.S. chronic hemodialysis centers and to determine the association between burnout and nurses' intentions to leave their jobs. Findings indicate that predictors were associated with an increased likelihood of nurse burnout and that nurses experiencing burnout were more likely to be planning to leave their jobs. Findings have important implications for retention of nurses, enhancement of patient safety, and adherence to new federal staffing requirements in chronic hemodialysis units.

Abstract

Objective To examine the relationships between nursing staffing levels and nursing home deficiencies.MethodsThis panel data analysis employed random-effect models that adjusted for unobserved, nursing home-specific heterogeneity over time. Data were obtained from California's long-term care annual cost report data and the Automated Certification and Licensing Administrative Information and Management Systems data from 1999 to 2003, linked with other secondary data sources.ResultsBoth total nursing staffing and registered nurse (RN) staffing levels were negatively related to total deficiencies, quality of care deficiencies, and serious deficiencies that may cause harm or jeopardy to nursing home residents. Nursing homes that met the state staffing standard received fewer total deficiencies and quality of care deficiencies than nursing homes that failed to meet the standard. Meeting the state staffing standard was not related to receiving serious deficiencies.ConclusionsTotal nursing staffing and RN staffing levels were predictors of nursing home quality. Further research is needed on the effectiveness of state minimum staffing standards.

Abstract

Background: This study examined conditions under which gingival crevicular blood (GCB) could be used to obtain a useful glucose reading to screen for undiagnosed diabetes during routine dental visits. Methods: GCB and capillary finger-stick blood (CFB) glucose readings obtained with a glucometer were compared for 46 patients recruited from an urban university dental clinic. Study participants were divided into two groups based on probing depth or bleeding on probing (BOP) at the site of collection of theGCBsample. Group 1 participants had blood collected from sites with adequate BOP to obtain a sample without touching the tooth or gingival margin, whereas group 2 participants had blood collected from sites with little or no bleeding. For each group, Pearson correlations were calculated for glucose readings obtained using GCB and CFB samples, and the limits of agreement between the two samples were examined. Results: For group 1 participants, correlations between CFB and GCB glucose readings were high (0.89), and the limits of agreement were acceptable (-27.1 to 29.7). By contrast, for participants in group 2, correlations between the glucose readings were lower (0.78), and limits of agreement were much broader (-25.1 to 80.5). Conclusion:GCBsamples were suitable to screen for diabetes in persons with sufficient BOP to obtain a sample without touching the tooth or gingival margin (i.e., in patients having the basic clinical signs of gingivitis or periodontal disease).

Abstract

Aim: To study the relationship between nurse work environment, job outcomes and nurse-assessed quality of care in the Belgian context. Background: Work environment characteristics are important for attracting and retaining professional nurses in hospitals. The Revised Nursing Work Index (NWI-R) was originally designed to describe the professional nurse work environment in U.S. Magnet Hospitals and subsequently has been extensively used in research internationally. Method: The NWI-R was translated into Dutch to measure the nurse work environment in 155 nurses across 13 units in three Belgian hospitals. Factor analysis was used to identify a set of coherent subscales. The relationship between work environments and job outcomes and nurse-assessed quality of care was investigated using logistic and linear regression analyses. Results: Three reliable, consistent and meaningful subscales of the NWI-R were identified: nurse-physician relations, nurse management at the unit level and hospital management and organizational support. All three subscales had significant associations with several outcome variables. Nurse-physician relations had a significant positive association with nurse job satisfaction, intention to stay the hospital, the nurse-assessed unit level quality of care and personal accomplishment. Nurse management at the unit level had a significant positive association with the nurse job satisfaction, nurse-assessed quality of care on the unit and in the hospital, and personal accomplishment. Hospital management and organizational support had a significant positive association with the nurse-assessed quality of care in the hospital and personal accomplishment. Higher ratings of nurse-physician relations and nurse management at the unit level had significant negative associations with both the Maslach Burnout Inventory emotional exhaustion and depersonalization dimensions, whereas hospital management and organizational support was inversely associated only with depersonalization scores. Conclusion: A Dutch version of the NWI-R questionnaire produced comparable subscales to those found by many other researchers internationally. The resulting measures of the professional practice environment in Belgian hospitals showed expected relationships with nurse self-reports of job outcomes and perceptions of hospital quality.

Abstract

The nurse-to-population ratio (NPOP) is a standard indicator used to indicate a country's health care human resources capacity for responding to its disease burden. This study sought to explore if socioeconomic development indicators could predict the NPOP in a country. Mexico served as the case example for this exploratory study, with the final five variables selected based on findings from a qualitative study analyzing the development of nursing human resources in the country. Multiple linear regression showed that two variables proved significant predictors of the NPOP and the model itself explained 70% of the variance (r2 =. 7; p =. 0000). The findings have multiple implications for nursing human resources policy in Mexico and at a global level as governments attempt to build human capital to respond to population health needs.

Abstract

Background: Many studies have examined predictors of nurses' intention to work in their job, including desire to quit. Intent has been a good predictor of actual turnover. Few longitudinal studies exist that consider regional variables. Objectives: To extend the conceptual framework of turnover research to the whole nursing workforce and determine: (1) how do demographics, region (metropolitan statistical area: MSA), movement opportunities, and work setting variables affect registered nurses' (RNs) intent to work and desire to quit; and (2) how do demographics, MSA variables, movement opportunities, and work setting variables affect RNs' work behavior at time 2? Design: Panel study using Dillman's design method. Settings and participants: Randomly selected national cluster sample from 40 urban geographic regions (MSAs) in 29 states of the United States. Methods: Four thousand surveys were sent. There were 1907 female RNs under 65 (48% response rate) from year 1 of which 1348 responded at year 2 (70% response rate). Results: The first analyses used desire to quit (explained 65% of the variance) and intent to work from year 1 as dependent variables. Satisfaction and organizational commitment were significant negative predictors of desire to quit. In the logistic regression on intent to work, the work motivation and work-family conflict were positive and significant as well as wages (negative) and three benefit variables. In year 2, the dependent variable was working or not and if working, full-time or not. For this bivariate probit regression no attitudes influenced the work/not work decision, but MSA level variables, wages (positive) and benefits (positive) did. Organizational commitment and higher workload increased the probability of working FT. Conclusions: Regional differences across markets need to be controlled and their influence investigated. In addition, attitudes as well as wages and benefits were important in certain decisions: these factors are clearly under the influence of employers.

Abstract

Although fatigue and sleep disturbance are prevalent symptoms in oncology patients and their family caregivers, little is known about the factors that contribute to interindividual variability in symptom severity ratings as well as in their underlying biological mechanisms. In this study, we sought to determine whether a functional genetic variation in a prominent proinflammatory cytokine, tumor necrosis factor-alpha (TNFA-308G>A [rs1800629] promoter polymorphism) was associated with overall ratings of sleep disturbance and fatigue as well as with the trajectories of these symptoms. Over 6 months, participants completed standardized measures of sleep disturbance and fatigue. Multiple linear regression was used to assess the effect of the TNFA genotype and other covariates on mean sleep disturbance and fatigue scores. Hierarchical linear modeling was used to determine the effect of TNFA genotype on the trajectories of these symptoms. Common allele homozygotes reported higher levels of sleep disturbance (p =.09) and morning fatigue (p =.02) than minor allele carriers. Multivariate analyses demonstrated that age and genotype were predictors of both mean symptom scores and the trajectories of these symptoms. Findings provide preliminary evidence of an association between a functional promoter polymorphism in the TNFA gene and the severity of sleep disturbance and morning fatigue in oncology patients and their family caregivers.

Abstract

Purpose: Evidence suggests that healthy lifestyles may help maintain cognitive health. The Prevention Research Centers Healthy Aging Research Network, 9 universities collaborating with their communities and the Centers for Disease Control and Prevention, is conducting a multiyear research project, begun in 2005, to understand how to translate this knowledge into public health interventions. Design and Methods: This article provides an overview of the study purpose, design, methods, and processes. We examined the literature on promoting cognitive health, convened a meeting of experts in cognitive health and public health interventions, identified research questions, developed a common focus group protocol and survey, established quality control and quality assurance processes, conducted focus groups, and analyzed the resulting data. Results: We conducted 55 focus groups with 450 participants in 2005-2007, and an additional 20 focus groups and in-depth interviews in 2007-2008. Focus groups were in English, Spanish, Mandarin, Cantonese, and Vietnamese, with African Americans, American Indians, Asian Americans, Hispanics, non-Hispanic Whites, physicians and other health practitioners, rural and urban residents, individuals caring for family or friends with cognitive impairment, and cognitively impaired individuals. Implications: The data provide a wealth of opportunities for designing public health interventions to promote cognitive health in diverse populations.

Abstract

Barriers to care contribute to health inequities for immigrant populations. Although inadequate health insurance is a known barrier, other factors impact the issue. Few instruments exist to specifically measure these other barriers. The purpose of this study was to test the Immigrant Barriers to Health Care Scale - Hispanic Version. It was first pilot-tested in southern California with a Mexican population. After refinement, the instrument was tested in a north-eastern sample of diverse Hispanic adults. The data were analyzed using exploratory factor analysis. Factor loadings and communalities were used to assess the adequacy of the scale's items. Six items were deleted due to ambiguous factor loadings. The final 11 items loaded onto four factors and explained 54.58% of the variance. The coefficient alpha was 0.81 for the instrument. The Immigrant Barriers to Health Care Scale is a reliable and valid tool. Its further use and reporting with other socially and economically disadvantaged groups is advised.

Abstract

The present review assesses the public's perceptions about cognitive health and Alzheimer's disease among adults in the United States. We searched the published literature and Internet, and contacted experts in the field to locate surveys assessing the public's perceptions about cognition. We found 10 eligible surveys and abstracted data concerning the public's knowledge, beliefs, concerns, and sources of information. Most of the surveys were conducted in the 2000s and focused on Alzheimer's disease rather then cognitive health. Based on the findings from the surveys, most adults were found to be aware of Alzheimer's disease but lacked specific information about the disease and its treatments. Most respondents did not perceive themselves as being very knowledgeable about Alzheimer's disease. Although we could classify the findings into several overarching domains, such as knowledge, we found considerable variability among surveys in the questions asked. Additional work is needed to understand the public's perceptions about cognitive health. Moreover, we also lack studies that help us understand perceptions about cognition across diverse demographic and cultural groups. Only by addressing these gaps can we develop targeted and effective strategies to enhance knowledge and beliefs about cognitive impairment and health.
