Abstract

Countries across the globe are experiencing nursing shortages. In hospitals, supportive practice environments have positive effects on both nurse and patient outcomes. However, these relationships have been established primarily in the US. International studies of the effects of nurse staffing levels and the practice environment on nurse outcomes and the quality of care mirror the findings from the US, thus raising these issues to the international level. The solutions that have been successful in the US for improving the practice environment and patient outcomes are solutions that should be successful in any country, thus putting them on a global scale. The Magnet hospital program is one model that has been shown to improve nurse and patient outcomes and is one solution to the shortage of hospital nurses.

Abstract

This article reports the results of a study carried out with 30 Mexican-origin immigrants in drug user treatment in the United States-Mexico Border city of El Paso, Texas during 2007. Qualitative, semi-structured interviews were implemented to assess the dynamic social and economic factors that affect the delivery and utilization of treatment services, with emphasis on the impact of recent immigration-related laws and policies. The research provides initial data for evidence-based intervention and reinforces the need for culturally and gender appropriate treatment services for poor immigrants and their families. The study's limitations are noted.

Abstract

Purpose: In a sample of family caregivers (FCs) of patients with prostate cancer who were to begin radiation therapy (RT), the purposes were to determine the prevalence and severity of depression, anxiety, pain, sleep disturbance, and fatigue; determine the relationships among these symptoms and between these symptoms and functional status and quality of life (QOL); evaluate for differences in functional status and QOL between FCs with low and high levels of these symptoms; and determine which factors predicted FCs' functional status and QOL. Patients and Methods: FCs were recruited before patients initiated RT and completed self-report questionnaires that evaluated demographic characteristics, symptoms, functional status, and QOL. Results: Sixty female FCs participated in the study. On the basis of established cut point scores for each symptom questionnaire, 12.2% of the FCs had clinically meaningful levels of depression, 40.7% anxiety, 15.0% pain, 36.7% sleep disturbance, 33.3% morning fatigue, and 30.0% evening fatigue. FCs who were older and who had lower levels of state anxiety and higher levels of depression, morning fatigue, and pain reported significantly poorer functional status (R2 = 38.7%). FCs who were younger, had more years of education, were working, and who had higher levels of depression, morning fatigue, sleep disturbance, and lower levels of evening fatigue reported significantly lower QOL scores (R2 = 70.1%). Conclusion: A high percentage of FCs experienced clinically meaningful levels of a variety of symptoms. These symptoms have a negative impact on the FCs' functional status and QOL.

Abstract

Objectives: Difficulties with diagnosis and aggressive, long-term treatment may result in lower quality of life (QOL), including high levels of anxiety, depression, and uncertainty, greater symptom distress, and lower overall QOL among women with avarian cancer. The purpose of this study was to describe demographic, clinical, and other risk factors associated with compromised QOL among women who have undergone surgery for avarian malignancies. Methods: Subjects were recruited to participate in a clinical trial that tested a specialized nursing intervention addressing psychological and physical care among women post-surgical for avarian cancer. QOL was measured using five standardized self-report measures: the State-Trait Anxiety Scale (SAS), the Center for Epidemiological Studies Depression Scale (CES-D), the Mishel Uncertainty in Illness Scale (MUIS), the Symptom Distress Scale (SDS), and the Short-Form Health Survey (SF-12). Baseline data were collected while women were hospitalized following surgery. Results: The sample (n=145) included women with avarian cancer (58%) and other cancers metastasized to the avaries and abdomen (42%). Mean scores on the measures were consistent with or higher than previously reported means for similar populations. Women reporting the lowest QOL were more likely to be younger, more educated, and have early stage disease. Significance of results: Women who have undergone surgery for ovarian malignancies have psychological needs that are often considered secondary to physical needs. Interventions should include routine screening for distress and referral to appropriate psychological and social services, thereby facilitating quality cancer care.

Abstract

Objectives. To explore the association between implicit rationing of nursing care and selected patient outcomes in Swiss hospitals, adjusting for major organizational variables, including the quality of the nurse practice environment and the level of nurse staffing. Rationing was measured using the newly developed Basel Extent of Rationing of Nursing Care (BERNCA) instrument. Additional data were collected using an adapted version of the International Hospital Outcomes Study questionnaire. Design. Multi-hospital cross-sectional surveys of patients and nurses. Setting. Eight Swiss acute care hospitals Participants. Nurses (1338) and patients (779) on 118 medical, surgical and gynecological units. Main outcome measures. Patient satisfaction, nurse-reported medication errors, patient falls, nosocomial infections, pressure ulcers and critical incidents involving patients over the previous year. Results. Generally, nurses reported rarely having omitted any of the 20 nursing tasks listed in the BERNCA over their last 7 working days. However, despite relatively low levels, implicit rationing of nursing care was a significant predictor of all six patient outcomes studied. Although the adequacy of nursing resources was a significant predictor for most of the patient outcomes in unadjusted models, it was not an independent predictor in the adjusted models. Low nursing resource adequacy ratings were a significant predictor for five of the six patient outcomes in the unadjusted models, but not in the adjusted ones. Conclusion. As a system factor in acute general hospitals, implicit rationing of nursing care is an important new predictor of patient outcomes and merits further study.

Abstract

Little attention has been given to the effects of registered nurse (RN) staffing and processes of nursing care on patient outcomes in hemodialysis units. This research examined the effects of patient-to-RN ratios and necessary tasks left undone by RNs on the likelihood of nurse-reported frequent occurrences of adverse patient events in chronic hemodialysis units. Study findings revealed that high patient-to-RN ratios and increased numbers of tasks left undone by RNs were associated with an increased likelihood of frequent occurrences of dialysis hypotension, skipped dialysis treatments, shortened dialysis treatments, and patient complaints in hemodialysis units. These findings indicate that federal, state, and dialysis organization policies must foster staffing structures and processes of care in dialysis units that effectively utilize the invaluable skills and services of professional, registered nurses.

Abstract

▶ Background: Although religion and spirituality are prominent in the lives of Black women with type 2 diabetes (T2DM), there is little research on the relationships of religion and spirituality to glycemic control (GC) in this population. ▶ Objective: To examine the relations of religion and spirituality to GC. ▶ Methods: Using a cross-sectional, descriptive, correlational design, a convenience sample of 109 Black women with T2DM was recruited. Measures of demographic (age, income, and education), clinical (body mass index and use of diabetes medications), psychosocial (emotional distress and social support), religion and spirituality (religious and existential well-being), and GC (hemoglobin A1c) factors were collected. A theoretical model, based on the work of Koenig, McCullough, and Larson (2001), informed linear regression analyses to examine the relations of religion and spirituality to GC, with psychosocial factors as putative mediators. ▶ Results: With age (β = -.133, SE = .020, p = .145), income (β =.020, SE = .139, p = .853), education (β = -.221, SE = .204, p = .040), body mass index (β= - .237, SE = .031, p = .011), and diabetes medications (β = .338, SE = .216, p < .001) held constant, religion and spirituality demonstrated significant relations with GC (β = .289, SE = .032, p = .028 and β = -.358, SE = .030, p = .006, respectively). Evidence of emotional distress and social support as mediators in the relationships of religion and spirituality to GC was lacking. ▶ Discussion: Religion and spirituality were related to GC, with evidence of psychosocial mediation lacking, thereby forcing revision of the model for the study population. Research is warranted to validate the findings, with further examination of theoretical mediators linking religion and spirituality to GC. Findings suggest that religion and spirituality be addressed in diabetes care to improve GC in Black women with T2DM.

Abstract

Aims: Recent large association studies have revealed associations between genetic polymorphisms and myocardial infarction and coronary heart disease (CHD). We performed a replication study of 10 polymorphisms and CHD in a population with familial hypercholesterolemia (FH), individuals at extreme risk of CHD. Methods and results: We genotyped 10 polymorphisms in 2145 FH patients and studied the association between these polymorphisms and CHD in Cox proportional hazards models. We confirmed the associations between four polymorphisms and CHD, the rs1151640 polymorphism in the olfactory receptor family 13 subfamily G member 1 (OR13G1) gene (HR 1.14, 95% CI 1.01-1.28, P = 0.03), the rs11881940 polymorphism in the heterogeneous nuclear ribonucleoprotein U-like 1 (HNRPUL1) gene (HR 1.27, 95% CI 1.07-1.51, P = 0.007), the rs3746731 polymorphism in the complement component 1 q subcomponent receptor 1 (CD93) gene (HR 1.26, 95% CI 1.06-1.49, P = 0.01), and the rs10757274 polymorphism near the cyclin-dependent kinase N2A and N2B (CDKN2A and CDKN2B) genes (HR 1.39, 95% CI 1.15-1.69, P < 0.001). Conclusion: We confirmed previously found associations between four polymorphisms and CHD, but refuted associations for six other polymorphisms in our large FH population. These findings stress the importance of replication before genetic information can be implemented in the prediction of CHD.

Abstract

Purpose/Objectives: To apply the Hanahan and Weinberg conceptual framework for tumor development to the specific biomarkers observed or expressed in ovarian cancer. Data Sources: Data-based publications, topical reviews, and book chapters. Data Synthesis: Articles specific to ovarian cancer were reviewed to examine whether the six rules from the Hanahan and Weinberg conceptual framework were applicable to biomarkers of ovarian cancer. This approach allows for the application of a general framework for the development of solid tumors to the development of ovarian cancer. Conclusions: The six rules for tumor cell development outlined in the Hanahan and Weinberg conceptual framework are applicable to biomarkers expressed or observed in patients with ovarian cancer. Implications for Nursing: Oncology nurses can enhance their clinical teaching by integrating this information into their practice. Nurses who conduct research on ovarian cancer can use this framework to guide the selection of biomarker(s) for these studies. Finally, nurse educators can use this framework when teaching students key concepts in the care of patients with cancer.

Abstract

Reducing sex risk behaviors among high-risk injection drug users (IDUs) and crack smokers is a continuing challenge for HIV prevention. Based on a longitudinal study of sexually active Puerto Rican IDUs and crack smokers in New York (n=573) and Puerto Rico (n=264), baseline predictors of changes in sex risk (number of unprotected sex acts) at 6- and 36-month follow-up interviews were examined. In New York, predictors of higher sex risk were being younger, having primary partners, having more other sex partners, never exchanging sex, having lower self-efficacy for reducing sex risk behaviors and being HIV-negative, and these predictors were significant at both postbaseline periods. In Puerto Rico, short-term predictors included being male, having primary partners, never exchanging sex, lower sex risk norms and lower self-efficacy. However, only having primary partners was significant in longer-term behaviors. Results indicated the need for enhancing self-efficacy and for developing risk reduction strategies related to community differences.

Abstract

Objective. To analyze corporate governance arrangements and quality and financial performance outcomes among large multi-facility nursing home corporations (chains) that pursue stakeholder value (profit maximization) strategies. Study Design. To establish a foundation of knowledge about the focal phenomenon and processes, we conducted an historical (1993-2005) case study of one of the largest chains (Sun Helathcare Inc.) that triangulated qualitative and quantitative data sources. Data Sources. Two main sets of information were compared: (1) corporate sources including Sun's Security Exchange Commission (SEC) Form 10-K annual reports, industry financial reports, and the business press; and (2) external sources including, legal documents, press reports, and publicly available California facility cost reports and quality data. Principal Findings. Shareholder value was pursued at Sun through three inter-linked strategies: (1) rapid growth through debt-financed mergers; (2) labor cost constraint through low nurse staffing levels; and (3) a model of corporate governance that views sanctions for fraud and poor quality as a cost of business. Conclusions. Study findings and evidence from other large nursing home chains underscore calls from the Institute of Medicine and other bodies for extended oversight of the corporate governance and performance of large nursing home chains.

Abstract

Objective: To identify processes affecting agency for safety among perinatal nurses, physicians, and certified nurse-midwives. Design: Grounded theory, as informed by Strauss and Schatzman. Setting: Two academic perinatal units in the western United States. Participants: Purposive sample of 12 registered nurses, 5 physicians, and 2 certified nurse-midwives. Findings: Agency for safety (the willingness to take a stand on an issue of concern) fluctuated for all types of providers depending on situational context and was strongly influenced by interpersonal relationships. While physicians and certified nurse-midwives believed that they valued nurses' contributions to care, their units had deeply embedded hierarchies. Nurses were structurally excluded from important sources of information exchange and from contributing to the plan of care. Nurses'confidence was a key driver for asserting their concerns. Confidence was undermined in novel or ambiguous situations and by poor interpersonal relationships, resulting in a process of redefining the situation as a problem of self. Conclusions: Women and babies should not be dependent on the interpersonal relationships of providers for their safety. Clinicians should be aware of the complex social pressures that can affect clinical decision making. Continued research is needed to fully articulate facilitators and barriers to perinatal safety.

Abstract

The association between socioeconomic status (SES) and current regular alcohol use was examined separately for urban and rural residents of Hubei, China, using the third Chinese National Health Service Survey conducted in 2003. A probability sample of 15,609 respondents, ages 15 through 101 years, was selected from the study base. Alcohol use was a dichotomized variable (current regular users vs. others). Multivariate analyses incorporated four SES indicators: income, education, occupation, and house size. Investigation of status discrepancy indicated that income was positively associated with the likelihood of current regular alcohol use, whereas education was negatively associated. For both urban and rural residents, likelihood of current regular alcohol use was smallest for those in the highest education and lowest income category. Further research, which factors in quantity and frequency, is needed to understand how alcohol use among Chinese urban and rural populations impacts their health.

Abstract

Objective: To explore the practice of midwifery within a busy urban tertiary hospital birth setting and to present findings on the relationships between nurses and midwives in providing maternity care. Design/Method: A focused ethnography on midwifery practice conducted over 2 years (2004-2006) in a teaching hospital serving a primarily Medicaid-eligible population in Northern California. Data were collected through participant observations and in-depth interviews with midwives (N = 11) and nurses (N = 14). Practices and relationships among the midwives and nurses were examined in an ethnographic framework through thematic analysis. Findings: Two themes described the nature of nursing-midwifery relationships: tension and teamwork. Tension existed in philosophic approaches to care, definitions of safe practice, communication, and respect. Teamwork existed when the midwives and nurses worked in partnership with the woman to develop a plan of care. Changes were brought about to improve the midwife-nurse relationship during the conduct of the study. Conclusions: Midwives and nurses experienced day-to-day challenges in providing optimal care for childbearing women. The power of effective teamwork was profound, as was the tension when communication broke down. Failure to include nurses resulted in impaired translation of evidence into practice. All stakeholders in birth practices and policy development must be involved in future research in order to develop effective maternity care models.

Abstract

Background. The hepatitis C virus (HCV) is hyper-endemic in injecting drug users. There is also excess HCV among non-injection drug users who smoke, snort, or sniff heroin, cocaine, crack, or methamphetamine. Methods. To summarize the research literature on HCV in drug users and identify gaps in knowledge, we conducted a synthesis of the relevant research carried out between 1989 and 2006. Using rigorous search methods, we identified and extracted data from published and unpublished reports of HCV among drug users. We designed a quality assurance system to ensure accuracy and consistency in all phases of the project. We also created a set of items to assess study design quality in each of the reports we included. Results. We identified 629 reports containing HCV prevalence rates, incidence rates and/or genotype distribution among injecting or non-injecting drug user populations published between January 1989 and December 2006. The majority of reports were from Western Europe (41%), North America (26%), Asia (11%) and Australia/New Zealand (10%). We also identified reports from Eastern Europe, South America, the Middle East, and the Caribbean. The number of publications reporting HCV rates in drug users increased dramatically between 1989 and 2006 to 27-52 reports per year after 1998. Conclusion. The data collection and quality assurance phases of the HCV Synthesis Project have been completed. Recommendations for future research on HCV in drug users have come out of our data collection phase. Future research reports can enhance their contributions to our understanding of HCV etiology by clearly defining their drug user participants with respect to type of drug and route of administration. Further, the use of standard reporting methods for risk factors would enable data to be combined across a larger set of studies; this is especially important for HCV seroconversion studies which suffer from small sample sizes and low power to examine risk factors.
