Abstract

PURPOSE: The majority of patients with type 2 diabetes mellitus (T2DM) have multiple risk factors for cardiovascular disease (CVD). Low-density lipoprotein cholesterol (LDL-C) is a key therapeutic target to reduce CVD risk. This article reviews therapeutic strategies that nurse practitioners (NPs) may use in the management of patients with T2DM requiring lipid management.DATA SOURCES: The evidence used in developing this review included evidence-based reviews, clinical trials, guidelines, and consensus statements. Relevant publications were identified through a search of the literature using PubMed and other search engines.CONCLUSIONS: Lowering LDL-C levels may reduce CVD risk, but achieving goals can be challenging. Lifestyle modifications (including diet, exercise, and smoking cessation) are key components of lipid management and reduction of CVD risk. Statins can be effective to reduce lipids. However, patients may not achieve lipid goals with monotherapy or may experience intolerable adverse effects. Alternative statins or statins along with other lipid-lowering agents remain good options.IMPLICATIONS FOR PRACTICE: Achieving LDL-C goals requires a comprehensive treatment plan that incorporates lifestyle and pharmacologic interventions. Patient commitment in setting goals and self-management is essential. NPs can play an important role in educating patients as well as prescribing appropriate treatments.

Abstract

Despite the substantial amount of useful prior work on turnover among nurses, our understanding of the causal mechanisms explaining why nurses voluntarily leave their jobs is limited. The purpose of this article is to promote the development of stronger conceptual models of the causes of voluntary turnover among nurses. The author compares the nursing-specific literature to research on voluntary turnover from the general management field over the past 30 years and examines the evolution of key theories used in the nursing literature. Results of this review comparing nursing research with that in the broader field suggest that, over time, nursing research has not kept pace with conceptualizations from general management explaining why people either remain at or quit their jobs. The author argues that conceptual models of turnover among nurses can benefit significantly from drawing more effectively on particular models and concepts available in general management studies of turnover.

Abstract

Context: Sleep disturbance is a problem for oncology patients. Objectives: To evaluate how sleep disturbance and daytime sleepiness (DS) changed from before to six months following surgery and whether certain characteristics predicted initial levels and/or the trajectories of these parameters. Methods: Patients (n = 396) were enrolled prior to surgery and completed monthly assessments for six months following surgery. The General Sleep Disturbance Scale was used to assess sleep disturbance and DS. Using hierarchical linear modeling, demographic, clinical, symptom, and psychosocial adjustment characteristics were evaluated as predictors of initial levels and trajectories of sleep disturbance and DS. Results: All seven General Sleep Disturbance Scale scores were above the cutoff for clinically meaningful levels of sleep disturbance. Lower performance status; higher comorbidity, attentional fatigue, and physical fatigue; and more severe hot flashes predicted higher preoperative levels of sleep disturbance. Higher levels of education predicted higher sleep disturbance scores over time. Higher levels of depressive symptoms predicted higher preoperative levels of sleep disturbance, which declined over time. Lower performance status; higher body mass index; higher fear of future diagnostic tests; not having had sentinel lymph node biopsy; having had an axillary lymph node dissection; and higher depression, physical fatigue, and attentional fatigue predicted higher DS prior to surgery. Higher levels of education, not working for pay, and not having undergone neo-adjuvant chemotherapy predicted higher DS scores over time. Conclusion: Sleep disturbance is a persistent problem for patients with breast cancer. The effects of interventions that can address modifiable risk factors need to be evaluated.

Abstract

Objectives. We investigated trends in activities of daily living (ADL) and instrumental activities of daily living (IADL) disability from 1998 to 2008 among elder adults in Shanghai, China.Method. Our data came from 4 waves of the Shanghai Longitudinal Survey of Elderly Life and Opinion (1998, 2003, 2005, and 2008). ADL and IADL disabilities were recorded dichotomously (difficulty vs. no difficulty). The major independent variable was survey year. Covariates included demographics, socioeconomic conditions, family and social support, and other health conditions. Nested random-effect models were applied to estimate trends over time, referenced to 1998.Results. In comparison with the baseline year (1998), older adults in 2008 had lower odds of being ADL disabled, though the effect was no longer statistically significant when other health conditions were taken into account. Elders in 2003, 2005, and 2008 were 20%-26%, 17%-38%, and 53%-64% less likely to be IADL disabled than those in 1998, respectively, depending on the set of covariates included in the model.Discussion. Shanghai elders experienced substantial improvements in both ADL and IADL disability prevalence over the past decade. The trend toward improvement in IADL function is more consistent and substantial than that of ADL function.

Abstract

Objectives. We estimated national trends of the prevalence of edentulism (complete tooth loss) for Asian American subgroups in the United States and investigated factors that could contribute to improvements in edentulism across populations over time. Methods. We used 10 waves of the National Health Interview Survey data collected from 1999 to 2008. Eligible respondents were those aged 50 years and older who completed the question on tooth loss. We contrasted the odds and probabilities of edentulism over time in Chinese, Filipinos, Asian Indians, and other Asians with those in Whites, Blacks, and Hispanics. Results. The rates of edentulism differed substantially across Asian subgroups. Compared with Whites, Chinese and other Asians had a lower risk of being edentulous, whereas being Filipino increased the odds. The rate for Asian Indians was similar to that for Whites. Nonetheless, rates of decline were similar across the Asian population groups. Conclusions. Asian Americans are heterogeneous in edentulism. Innovative and sustainable public health programs and services are essential to prevent oral health diseases and conditions.

Abstract

This article draws from a study investigating the influence of institutional and psychosocial factors on adherence to antiretroviral (ARV) medications by Mexican-origin persons living with HIV (PWLH) on the U.S.-Mexico border and seeking treatment at a clinic in El Paso, Texas. Among 113 participants, many individuals reported using complementary and alternative medicines (CAM) to support general health and their immune systems and to address symptoms of HIV-related diseases and ARV side effects. CAM were seen as complementing ARV treatment; however, CAM use was often not reported to health care providers out of concern about disapproval and loss of care privileges. This finding challenges researchers and providers to consider seriously how Hispanic populations, with their CAM use, may exhibit the hybridization of health and healing. Information on CAM use needs to be available to providers to assess the benefits and contraindications of use and to develop realistic and effective care strategies.

Abstract

An integral part of NICHE (Nurses Improving Care for Healthsystem Elders) is a benchmarking service that provides member sites with the ability to evaluate staff perceptions of the care environment compared with other NICHE sites. The NICHE Database includes more than 100,000 surveys (Geriatric Institutional Assessment Profile). This study aimed to explain how secondary analyses of this aggregate database can inform effective geriatric programming in hospitals. We found that nurse age and experience influence nurse perceptions of organizational alignment to NICHE guiding principles and that those perceptions improve following NICHE implementation. The NICHE Database addresses knowledge generation in key areas of geriatric nursing practice and assists hospitals' systemic capacity to effectively embed NICHE Guiding Principles: evidence-based geriatric knowledge, patient-family centered care, healthy and productive practice environment, and multidimensional metrics of quality. It contributes to the growing field of implementation science that seeks to promote the uptake of research findings into clinical practice.

Abstract

Purpose: This study examined relationships between verbal abuse from nurse colleagues and demographic characteristics, work attributes, and work attitudes of early career registered nurses (RNs). Design and Methods: Data are from the fourth wave of a national panel survey of early career RNs begun in 2006. The final analytic sample included 1,407 RNs. Descriptive statistics were used to describe the sample, analysis of variance to compare means, and chi square to compare categorical variables. Findings: RNs reporting higher levels of verbal abuse from nurse colleagues were more likely to be unmarried, work in a hospital setting, or work in a non-magnet hospital. They also had lower job satisfaction, and less organizational commitment, autonomy, and intent to stay. Lastly, they perceived their work environments unfavorably. Conclusions: Data support the hypothesis that early career RNs are vulnerable to the effects of verbal abuse from nurse colleagues. Although more verbal abuse is seen in environments with unfavorable working conditions, and RNs working in such environments tend to have less favorable work attitudes, one cannot assume causality. It is unclear if poor working conditions create an environment where verbal abuse is tolerated or if verbal abuse creates an unfavorable work environment. Clinical Relevance: There is a need to develop and test evidence-based interventions to deal with the problems inherent with verbal abuse from nurse colleagues.

Abstract

Lifestyle changes such as in physical exercise, social activity, and diet can mitigate cognitive decline and improve quality of life in caregivers and care recipients with cognitive impairment. However, caregiver perspectives on lifestyle change remain largely unexamined. This study compares perspectives among caregivers for those with dementia and those with mild cognitive impairment (MCI). Interviews were conducted with caregivers in two sites in China, and thematic similarities and differences were examined between the two groups. Caregivers from both groups identified exercise, social activity, and diet as healthy ways of life. Differences were found in approaching lifestyle change based on health of the care recipient. Caregivers for patients with dementia found more often that they had no time or possibility for change, while caregivers for individuals with MCI were more often hopeful about change.

Abstract

Introduction: Students aged 16-24 years are at greatest risk for interpersonal violence and the resulting short and long-term health consequences. Electronic survey methodology is well suited for research related to interpersonal violence. Yet methodological questions remain about best practices in using electronic surveys. While researchers often indicate that potential participants receive multiple emails as reminders to complete the survey, little mention is made of the sender of the recruitment email. The purpose of this analysis is to describe the response rates from three violence-focused research studies when the recruitment emails are sent from a campus office, researcher or survey sampling firm. Methods: Three violence-focused studies were conducted about interpersonal violence among college students in the United States. Seven universities and a survey sampling firm were used to recruit potential participants to complete an electronic survey. The sender of the recruitment emails varied within and across the each of the studies depending on institutional review boards and university protocols. Results: An overall response rate of 30% was noted for the 3 studies. Universities in which researcherinitiated recruitment emails were used had higher response rates compared to universities where campus officials sent the recruitment emails. Researchers found lower response rates to electronic surveys at Historically Black Colleges or Universities and that other methods were needed to improve response rates. Conclusion: The sender of recruitment emails for electronic surveys may be an important factor in response rates for violence-focused research. For researchers identification of best practices for survey methodology is needed to promote accurate disclosure and increase response rates.

Abstract

Achieving health equity by improving the health care of all racial/ethnic groups is one of the key goals of Healthy People 2020. The implementation of evidence based practice (EBP) has been a major recommendation to achieve health equity in hopes of eliminating the subjectivity of clinical decision making. However, health disparities among racial/ethnic minorities are persistent in spite of the adoption of standardized care based on evidence. The EBP with racial and ethnic minorities is often seen as a possible cause of health and health care disparities. Three potential issues of using EBP to reduce health disparities have been identified: (1) a lack of data for EBP with ethnic/racial minority populations; (2) limited research on the generalizability of the evidence based on a European-American middle-class; and (3) sociocultural considerations in the context of EBP. Using EBP to reduce disparities in health care and health outcomes requires that nurse professionals should know how to use relevant evidence in a particular situation as well as to generate knowledge and theory which is relevant to racial/ethnic minorities. In addition, EBP implementation should be contextualized within the sociocultural environments in which patients are treated rather than solely focusing on the health problems.

Abstract

Burnout and work engagement are two sides of one coin, two opposite poles related not only to how workers personally experience their jobs but also to how they experience their jobs within the context of work teams/groups. Engaged workers have a lot of energy, are very enthusiastic about their jobs and are absorbed by their work. Nurses' job performance in hospitals, including psychiatric hospitals, is dependent upon their relationships with physicians and other healthcare workers and their superiors, how they are involved in the decisions about their work and whether or not they are provided with the right resources and adequate support. When nursing teams are able to perform well, nurses tend to be more engaged and satisfied with their jobs and are more willing to stay in their positions. Engaged nursing teams report better quality of patient care in psychiatric hospitals. Research in healthcare settings reveals important links between work environment factors, burnout and organizational outcomes. Recently, research focuses on work engagement, the opposite (positive) pole from burnout. The current study investigated the relationship of nurse practice environment aspects and work engagement (vigour, dedication and absorption) to job outcomes and nurse-reported quality of care variables within teams using a multilevel design in psychiatric inpatient settings. Validated survey instruments were used in a cross-sectional design. Team-level analyses were performed with staff members (n=357) from 32 clinical units in two psychiatric hospitals in Belgium. Favourable nurse practice environment aspects were associated with work engagement dimensions, and in turn work engagement was associated with job satisfaction, intention to stay in the profession and favourable nurse-reported quality of care variables. The strongest multivariate models suggested that dedication predicted positive job outcomes whereas nurse management predicted perceptions of quality of care. In addition, reports of quality of care by the interdisciplinary team were predicted by dedication, absorption, nurse-physician relations and nurse management. The study findings suggest that differences in vigour, dedication and absorption across teams associated with practice environment characteristics impact nurse job satisfaction, intention to stay and perceptions of quality of care.

Abstract

BACKGROUND:: The impact of registered nurse (RN) staffing on patient care quality has been extensively studied. Identifying additional modifiable work environment factors linked to patient care quality is critical as the projected shortage of approximately 250,000 RNs over the next 15 years will limit institutions' ability to rely on RN staffing alone to ensure high-quality care. PURPOSE:: We examined the association between RNs' ratings of patient care quality and several novel work environment factors adjusting for the effects of two staffing variables: reported patient-to-RN ratios and ratings of staffing adequacy. METHODOLOGY:: We used a cross-sectional, correlational design and a mailed survey to collect data in 2009 from a national sample of RNs (n = 1,439) in the United States. A multivariate logistic regression was used to analyze the data. FINDINGS:: Workgroup cohesion, nurse-physician relations, procedural justice, organizational constraints, and physical work environment were associated with RNs' ratings of quality, adjusting for staffing. Furthermore, employment in a Magnet hospital and job satisfaction were positively related to ratings of quality, whereas supervisory support was not. PRACTICE IMPLICATIONS:: Our evidence demonstrates the importance of considering RN work environment factors other than staffing when planning improvements in patient care quality. Health care managers can use the results of our study to strategically allocate resources toward work environment factors that have the potential to improve quality of care.

Abstract

Women's health care providers have noted an increased infant mortality rate among Ghanaian immigrants. We conducted focus groups with 17 women in Ghana. We asked them how they maintained their health both before and during pregnancy. When discussing their health, women repeatedly described the conditions or context of their daily lives and the traditional practices that they used to stay healthy. Knowledge of women's lives, the health care system that they previously used, and their cultural practices can be utilized by health care providers to more fully assess their patients and design more culturally appropriate care for this group of women.

Abstract

An eight-point action plan is proposed for lowering costs associated with end-of-life health care in the United States, as well as improving the quality of life experienced by patients and their families. This action plan was derived from an analysis of the six articles presented in this special issue of Nursing Ecanomic$. The two major features of this action plan are: (a) expansion of hospice and palliative care, as well as (b) increased use of advance directives. Additionally, as pre-conditions for the effective operation of this action plan, the political, cultural, and legislative contexts that merit attention are discussed. Finally, arguments as to the desirability, feasibility, and sustainability of this action plan are offered.

Abstract

Background: Clinicians use CA125, a tumor-associated antigen, primarily to monitor epithelial ovarian cancer. However, CA125 lacks the sensitivity and specificity necessary for population-based screening in healthy women. The purpose of this study was to determine if serum concentrations of CA125 differed across the three phases of the menstrual cycle in healthy, premenopausal women using two commercially available assays. Methods: Healthy, Caucasian women between the ages of 18 and 39 were enrolled using strict criteria to exclude factors known to contribute to CA125 fluctuations. Menstrual cycle regularity was determined using calendars maintained by participants for 3 months. After cycle regularity was established, blood was drawn at three time points for CA125 determination using two commercial assays (i.e., Siemens and Panomics). Results: Regardless of the assay used, CA125 values were highest during menses. The CA125 values decreased 0.2 U/ml per day from menses to the end of the same cycle, which resulted in a net decrease of 5.8 U/ml across the cycle. Conclusions: The two commercial assays for CA125 determination demonstrated good concordance in terms of reference ranges regardless of epitope differences. While CA125 levels changed over the course of the menstrual cycle, these changes may not be clinically significant in healthy women. This study is the first to control for factors known to contribute to CA125 elevations; to quantify a decrease in CA125 levels across the menstrual cycle; and to confirm concordance in the relative decreases in serum CA125 levels across the menstrual cycle between two frequently used commercial assays.

Abstract

Context: Sleep disturbance is a significant problem in oncology patients. Objectives: To examine how actigraphy and self-report ratings of sleep disturbance changed over the course of and after radiation therapy (RT); investigate whether specific patient, disease, and symptom characteristics predicted the initial levels and/or the characteristics of the trajectories of sleep disturbance; and compare predictors of subjective and objective sleep disturbance. Methods: Patients (n = 73) completed self-report questionnaires that assessed sleep disturbance, fatigue, depressive symptoms, anxiety, and pain before the initiation of RT through four months after the completion of RT. Wrist actigraphy was used as the objective measure of sleep disturbance. Hierarchical linear modeling was used for data analyses. Results: Mean wake after sleep onset was 11.9% and mean total score on the General Sleep Disturbance Scale was 45. More than 85% of the patients had an abnormally high number of nighttime awakenings. Substantial interindividual variability was found for both objective and subjective measures of sleep disturbance. Body mass index predicted baseline levels of objective sleep disturbance. Comorbidity, evening fatigue, and depressive symptoms predicted baseline levels of subjective sleep disturbance, and depressive symptoms predicted the trajectory of subjective sleep disturbance. Conclusion: Different variables predicted sleep disturbance using subjective and objective measures. The slightly elevated wake after sleep onset found may be an underestimation of the degree of sleep disturbance when it is evaluated in the context of the high number of nighttime awakenings and patient's perception of poor sleep quality and quantity.

Abstract

An important domain that emerged from the interpretation of 91 nurse manager (NM) narratives was achieving the right relationship between a NM and a recalcitrant staff member. This article depicts the qualitative distinctions in 2 stages of NM practice to show the importance of reflection on experiential learning in the development of expertise. This work confirms that NM development is more complex than teaching a curriculum of business and management theory and should include teaching for mastery of the skilled know-how of clinical leadership practice and formation of the person as manager.

Abstract

Background: This pilot study examines whether a novel diabetes screening approach using gingival crevicular blood (GCB) could be used to test for hemoglobin A1c (HbA1c) during periodontal visits. Methods: Finger-stick blood (FSB) samples from 120 patients and GCB samples from those patients with adequate bleeding on probing (BOP) were collected on special blood collection cards and analyzed for HbA1c levels in a laboratory. The Pearson correlation coefficient was used to measure correlation between FSB and GCB HbA1c values for 75 paired FSB and GCB samples. A receiver-operator characteristic curve (ROC) analysis was performed to determine an optimal GCB HbA1c criterion value for a positive diabetes screen. Results: For the 75 paired samples, the Pearson correlation coefficient was 0.842. The ROC analysis identified a criterion value of 6.3% for the GCB HbA1c test with high sensitivity (0.933) and high specificity (0.900), corresponding to FSB HbA1c values ≥6.5% (in the diabetes range). Using this GCB HbA1c criterion value for 27 additional paired samples, in which there was an unidentified component observed to coelute within the elution window of GCB HbA1c in the laboratory, there was agreement between FSB and GCB values for 24 of the pairs according to whether both were within or outside of the diabetes range. Conclusion: Using a criterion value of 6.3%, GCB samples are acceptable for HbA1c testing to screen for diabetes in most persons with BOP at the GCB collection site.

Abstract

Objective: Puerto Rico has one of the fastest growing HIV epidemics in the United States and - consistent with patterns observed in the Caribbean region as a whole - data on new infections shows the increased influence of sexual transmission in the local epidemic. Historically, both epidemiology and prevention activities have focused primarily on the islands' large heroin injector population. Although the available surveillance data indicate high rates of STIs and HIV among men who have sex with men (MSM), there has been little social and behavioral research among MSM and hence little empirical information to inform intervention development and planning. Methods: Given the absence of data on MSM and their importance in the emerging epidemic on the island, this paper describes a sample of MSM patients in an STI/ HIV treatment center in the San Juan metropolitan area between October 2009 and June 2011 (n=120). Assessment of sexual risk includes measures of onset of oral, vaginal, and anal sex, as well as current sexual practices and partner characteristics. Self-reported history of STI diagnoses and current HIV status are described. Results: Overall, MSM evidenced relatively large numbers of multiple, concurrent sexual partners, substantial age-discordance among partners, and limited condom use. Relative to HIV-negative MSM, HIV-positive MSM have had more cumulative male sexual partners in anal intercourse (p=0.005). HIV-negative MSM were more likely to have had sex without a condom at last receptive anal intercourse (p=0.012) as well as at last insertive anal sex intercourse (p=0.001). Conclusion: Priorities for advancing HIV interventions for MSM are delineated, including the need for targeted sexual health interventions, mental health services, and improved strategies for engaging and retaining MSM in health services.

Abstract

Background: Many women stop smoking during pregnancy. Factors associated with relapse are known, but no intervention prevents the return to smoking among pregnant women. The objective of this study was to determine why women return to smoking after prolonged abstinence during pregnancy by examining mothers' intention to smoke at the time of delivery and the perceptions that shape their intention. Methods: We conducted in-depth, semi-structured interviews during their postpartum hospital stay with 24 women who stopped smoking while pregnant. We asked participants whether they intended to resume smoking after pregnancy and why. Transcripts were analyzed using grounded theory-based qualitative methods to identify themes. Results: Participants ranged in age from 18 to 36years, and 63 percent were white. Three themes emerged from the interviews with the mothers: 1) they did not intend to return to smoking but doubted whether they would be able to maintain abstinence; 2) they believed that it would be possible to protect their newborns from the harms of cigarette smoke; and 3) they felt that they had control over their smoking and did not need help to maintain abstinence after pregnancy. Conclusions: Although most participants did not intend to resume smoking, their intentions may be stymied by their perceptions about second-hand smoke and by their overestimation of their control over smoking. Further study should quantify these barriers and determine their evolution over the first year after pregnancy with the goal of informing more successful, targeted interventions.
