Abstract

Computerized drug utilization review (DUR) can potentially reduce adverse drug events. We examined automated DUR for home healthcare patients with diabetes or hypertension. Sixty-eight percent of diabetes patients and 50.7% of hypertension patients triggered severe, moderate, or duplicative alerts. Among diabetes patients, 74.3% of duplicative alerts were trivial or inappropriate, compared with 3.9% among hypertension patients. Experts judged that 40.5% of high-risk diabetes patients and 53.6% of hypertension patients had alerts requiring nurse follow-up. Adequate follow-up was significantly lower for the former. The relationship between inappropriate alerts and poorer follow-up reinforces the need for more specific alert systems to focus clinicians' attention on clinically important alerts.

Abstract

Purpose: To examine the factors that influence the work satisfaction of a national sample of registered nurses in metropolitan statistical areas (MSAs). Design: A cross-sectional mailed survey design was used. The sample consisted of RNs randomly selected from 40 MSAs in 29 states; 1,907 RNs responded (48%). The sample of 1,538 RNs working in nursing was used for analysis. Methods: The questionnaire included measures of work attitudes and demographic characteristics. The data were analyzed using ordinary least-squares regression. Findings: More than 40% of the variance in satisfaction was explained by the various work attitudes: supervisor support, work-group cohesion, variety of work, autonomy, organizational constraint, promotional opportunities, work and family conflict, and distributive justice. RNs who were White, self-perceived as healthy, and working in nursing education were more satisfied. RNs that were more career oriented were more satisfied. Of the benefits options, only paid time off was related to satisfaction. Conclusions: Work-related factors were significantly related to RNs' work satisfaction.

Abstract

Objective. To analyze factors that are related to whether registered nurses (RNs) work (WK) or do not work (NW) in nursing; and if the RN works, whether she works full- (FT) or part-time (PT). Data Sources. Secondary data from National Sample Survey of Registered Nurses 2000 (NSSRN), the InterStudy Competitive Edge Part III Regional Market Analysis (2001), and the Area Resource File (2002). Study Design. Using a cross-sectional design we tested the relationship between WK or NW and FT or PT; and demographic, job-related, and metropolitan statistical area (MSA)-level variables. Data Collection/Extraction Methods. We combined the data sources noted above to produce the analytic sample of 25,471 female RNs. Principal Findings. Working in nursing is not independent of working FT or PT. Age (55 and older), other family income, and prior other work experience in health care are negatively related to working as an RN. The wage is not related to working as an RN, but negatively influences FT work. Age, children, minority status, student status, employment status, other income, and some job settings have a negative impact on working FT. Previous health care work has a positive effect on whether married RNs worked. Married RNs who are more dissatisfied are less likely to work FT. A greater number of market-level factors influence FT/PT than WK/NW behavior. Conclusions. An important contribution of this study is demonstrating that MSA-level variables influence RN work behavior. The market environment seems to have little effect on whether a nurse works, but is influential on how much the nurse works, and has differential effects on married versus single nurses.

Abstract

Nonalcoholic fatty liver disease (NAFLD) is a metabolic liver disease with widely variable phenotypes extending from simple steatosis, through nonalcoholic steatohepatitis (NASH) to cirrhosis and hepatocellular carcinoma. Inevitably, this reflects the interplay of well-recognized environmental factors and disease associations such as obesity and insulin resistance with host genetic factors, which are polygenic or complex in nature. Most of the observed phenotypic variability will probably be explained by variations in single nucleotide polymorphism frequency, although knowledge of the effect of most polymorphisms on biologic function is currently limited. Several observational studies of kindred with NASH suggest a genetic contribution. Most data characterizing genetic variation in different NAFLD phenotypes is derived from case-control association studies involving putative candidate genes. These candidate genes have been selected largely based upon the "two-hit hypothesis" of the pathogenesis of NAFLD, although other hypothesis-independent approaches can also be informative in gene selection. Thus far, candidate gene association studies have had significant limitations such as small cohort sizes and poor reproducibility. Rapid technologic developments are increasing the capability of detecting genetic variation. Identification of the genetic contribution to NAFLD will inform theories of disease pathogenesis and progression and ultimately improve management.

Abstract

Phospholipid transfer protein (PLTP) participates in key processes in lipoprotein metabolism, including interparticle phospholipid transfer, remodeling of HDL, cholesterol and phospholipid efflux from peripheral tissues, and the production of hepatic VLDL. The impact of PLTP on reverse cholesterol transport suggests that the gene may harbor sequence anomalies that contribute to disorders of HDL metabolism. The human PLTP gene was screened for sequence anomalies by DNA melting analysis in 276 subjects with hypoalphalipoproteinemia (HA) and 364 controls. The association with plasma lipid parameters was evaluated. We discovered 18 sequence variations, including four missense mutations and a novel polymorphism (c.-34G>C). In healthy controls, the c.-34G>C minor allele was associated with higher high density lipoprotein-cholesterol (HDL-C) and was depleted in subjects with HA. Linear regression models predict that possession of the rare allele decreases plasma triglyceride (TG) and TG/HDL-C and increases HDL-C independent of TG. Decreased PLTP activity was observed in one (p.R235W) of four (p.E72G, p.S119A, p.S124Y, and p.R235W) mutations in an in vitro activity assay. These findings indicate that PLTP gene variation is an important determinant of plasma lipoproteins and affects disorders of HDL metabolism.

Abstract

The most common form of von Willebrand disease (VWD) is reported to be type 1, accounting for as much as 80% of reported cases. With prevalence estimates as high as 1.6% in the general population, upwards of 4.5 million Americans may be affected. Unfortunately, VWD type 1 is also the most difficult type to diagnose. Despite the continuing progress in defining the genetic lesions responsible for VWD types 2 and 3, identification of the genetic determinants of VWD type 1 remains elusive. Herein the phenomenon known as VWD is summarized, the challenges associated with the diagnosis of type 1 VWD are described, and the role of genetic research in meeting these challenges is explored. The authors identify key gaps in the current genetics literature and suggest new avenues for future research. Lastly, they explore the role of nurses in this research and clinical endeavor. To the authors'knowledge, this review is the first to address these complex issues in nursing research.

Abstract

Purpose: The purpose of this descriptive study was to describe attainment of glucose and coronary heart disease (CHD) risk factor goals and to identify factors that were associated with successful goal achievement. Methods: A cross-sectional survey enrolled 110 subjects with type 2 diabetes undergoing screening for asymptomatic myocardial ischemia. Results: Many participants had HbA1c levels ≥7% (45%), and 46% to 79% were not meeting goals for CHD risk reduction. Individual factors of age, gender, and anxiety; the illness-related factor of lipid-lowering therapy; and the family-related factor of living alone were independently associated with 1 of the 7 outcomes under study. Illness-related factors of a longer duration of diabetes were strongly associated with glucose and blood pressure control, insulin use with glucose control and waist circumference, and antihypertensive use with blood pressure, triglycerides, and body mass index. Family-related factors of higher income were significantly associated with poorer glucose control and higher body mass index, while higher levels of perceived support by family and friends were associated with a lower risk of not meeting lipid goals. However, individual factors, represented by several aspects of personal model beliefs (exercising regularly, testing glucose, and checking one's feet) and physical activity, were consistently related to lipid and weight control. Conclusions: A variety of factors were associated with control of blood glucose and CHD risk factors, suggesting that a one-size-fits-all approach to multiple risk factor reduction efforts may not result in goal attainment.

Abstract

Objective: Older adults are less likely than other age groups to participate in clinical decision-making. To enhance participation, we sought to understand how older adults consider and discuss their life and health goals during the clinical encounter. Methods: We conducted six focus groups: four with community-dwelling older persons (n = 42), one with geriatricians and internists (n = 6), and one with rehabilitation nurses (n = 5). Participants were asked to discuss: patients' life and health goals; communication about goals, and perception of agreement about health goals. Group interactions were tape-recorded, transcribed, and analyzed using content analysis. Results: All participants were willing to discuss goals, but varied in the degree to which they did so. Reasons for non-discussion included that goal setting was not a priority given limited time, visits focused on symptoms, mutual perception of disinterest, and the presumption that all patients' goals were the same. Conclusion: Interventions to enhance goal setting need to address key barriers to promoting goals discussions. Participants recognized the benefits of goal setting, however, training and instruments are needed to integrate goal setting into medicine. Practice implications: Setting goals initially and reviewing them periodically may be a comprehensive, time-efficient way of integrating patients' goals into their care plans.

Abstract

Staff in drug treatment programs are in an optimal position to support the hepatitis C related needs of their patients. To do so effectively, however, staff need to have accurate information about the hepatitis C virus (HCV). This article examines the HCV knowledge of staff (N = 104) in two drug-free and two methadone maintenance treatment programs (MMTPs) in the New York metropolitan area. Five of 20 items on an HCV Knowledge Assessment were not answered correctly by the majority of the participating staff, and total scores on the Assessment averaged 70%, 71%, and 45% among the medically credentialed staff, non-medically credentialed staff in the MMTPs, and non-medically credentialed staff in the drug-free programs, respectively. The majority of those in the latter group had never participated in a training specifically devoted to HCV. Results suggest the need for effective HCV-related training for all staff in drug treatment programs.

Abstract

In recent years, CVD risk factors have been recognized among individuals living with HIV/AIDS (Dube et al., 2003) and have been associated with the medication regimen (HAART) used to manage the diseases. A specific class of HIV medication, protease inhibitors, has been implicated in elevating serum levels of triglyceride and cholesterol in treated individuals (Green, 2002; Penzak & Chuck, 2000). However, current treatments for hyperlipidemia in HIV are not always effective and can be dose-limited due to interactions with HAART regimens (Currier, 2002). Dietary guidelines by the NCEP have been recommended as the first-line approach to managing this condition. Well-controlled studies are needed to test the effectiveness of the NCEP diet on HIV-positive individuals. Published studies have focused primarily on dietary counseling and have lacked randomization, control groups, and adequate description of the counseling intervention. Because the mechanism associated with dyslipidemia and HAART is not fully understood, rigorously controlled dietary studies may provide the opportunity to investigate how diet metabolically affects lipid levels during HAART treatment.

Abstract

BACKGROUND: Changes in sexual risk behaviour may occur following HIV-1 infection. OBJECTIVE: To test the hypothesis that HIV-1 seroconversion and disease progression are associated with changes in risk behaviours, using data from a cohort of Kenyan female sex workers (FSWs). METHODS: HIV-1-seronegative FSWs were enrolled in a prospective cohort study of risk factors for HIV-1 acquisition. At monthly visits, standardized interviews were conducted to assess sexual risk behaviour and HIV-1 serologic testing was performed. Seroconverters were invited to continue with follow-up. Between 1993 and 2004 (when antiretroviral therapy was introduced in the cohort), 265 women seroconverted for HIV-1 (incidence 7.7/100 person-years) and were included in this analysis. RESULTS: Unprotected intercourse was reported at 546/2037 (27%) pre-seroconversion visits versus 557/3732 (15%) post-seroconversion visits (P < 0.001). These findings remained significant after adjustment for potential confounding factors [adjusted odds ratio (AOR) 0.69; 95% confidence interval (CI), 0.55-0.86]. Compared with HIV-1-seronegative women, there was a progressive stepwise decrease in unprotected intercourse among HIV-1-seropositive women with CD4 cell counts ≥ 500 (AOR, 0.93; 95% CI, 0.62-1.39), 200-499 (AOR, 0.58; 95% CI, 0.41-0.82) and < 200 cells/μl (AOR, 0.45; 95% CI, 0.25-0.82). Decreases in unprotected intercourse reflected increases in both abstinence and 100% condom use. Women also reported fewer partners and fewer episodes of intercourse after HIV-1 seroconversion. CONCLUSIONS: HIV-1 seroconversion and disease progression were associated with decreases in sexual risk behaviour among Kenyan FSWs.

Abstract

The purpose of this article was to synthesize the findings of six qualitative studies on homeless adolescent mothers. Metasynthesis was conducted using the meta-ethnographic approach of Noblit and Hare [Noblit, G., & Hare, R. (1988). Meta-ethnography: Synthesizing qualitative studies. Newbury Park, CA: Sage Publications]. Six reciprocal translations illuminating the experiences of homeless adolescent mothers emerged: being homeless, enduring abuse, lamenting lost years, searching for support, recreating self, and seeking a better life. The findings may be used by nurses working with this population as the basis for a framework of intervention strategies directed toward helping these mothers cope with their dual transitions into motherhood and adulthood while simultaneously being homeless.

Abstract

Because the HIV pandemic undergoes continual change in its locations and affected populations, it is crucial to study HIV risk behaviors among mobile and immigrant groups within and across borders. The impact of cross-cultural migrations and the importance of studying that impact in terms of demographic characteristics as well as cultural and environmental factors has not received adequate attention in public health research. This collaborative analysis utilizes data from three studies of immigrant groups in New York to describe and compare these factors that provide the context for risk and prevention of HIVAIDS and other health challenges. Data discussed were obtained utilizing multi-method approaches to identify and describe HIV risks among both new and more established immigrant populations within the urban settings of North America, with NYC as a central focus. Demographic and epidemiological data situate the analysis within the larger contexts of US migration and the HIV/AIDS epidemic in NYC. The authors identify risk and protective factors embedded to varying degrees in immigrants' multiple cultures and sub-cultures. The three populations studied include: 1) new Hispanic immigrants from the Dominican Republic, Mexico and Central America; 2) West Indian (Caribbean) immigrants from Jamaica, Trinidad/Tobago and other anglophone Caribbean nations; and 3) South Asian immigrants from India (Indian Americans). The paper seeks differences and commonalities, focusing on the social, attitudinal and behavioral factors that contribute to increased HIV/AIDS vulnerability among these populations. The data presented also identify some of the attitudes and behaviors of individuals and groups, as well as other facilitators and obstacles to transmission for immigrants as they adapt to new environments. Topics addressed include factors affecting HIV/AIDS vulnerability of immigrant groups, goals and expectations, health and mental heath issues, gender role change, sexual risk, alcohol and other drug use, perception of HIV/AIDS risk and implications for prevention.

Abstract

It is not practical to wait for a disaster, whether natural or human-made, to learn how to respond and provide specialized care. The Long Island University School of Nursing in Brooklyn, New York, has developed a specific educational experience for undergraduate nursing students enrolled in community health. The course is offered in the senior semester and includes didactic material based on the International Nursing Coalition for Mass Casualty Education-recommended competencies. Students are given the opportunity to apply the learning and develop additional skills by participating in a mock drill. Although anecdotal comments from the students indicate that the coursework has been helpful, additional research is planned to evaluate the program.

Abstract

Computers and the Internet provide researchers with new options in surveying. When using electronic surveys, several practical and methodological issues need to be considered such as whether the majority of the surveyed population has Internet access and whether an e-mail or a Web-based survey is most appropriate. Other important considerations relate to Internet security issues and, in international research, the possibility of language barriers. Despite these challenges, electronic surveys offer a promising alternative to conventional mail surveys.

Abstract

IPV presents a serious health risk to many women. Emergency and critical care nurses are in a prime position for identification of and intervention with these women. Careful assessment and recognition of symptoms and conditions associated with IPV helps nurses to identify victims and potential victims. Building a trusting and supportive environment, where women feel comfortable disclosing abuse, precedes effective intervention. Nursing practice can incorporate the myriad resources and successful programs to provide victims with quality care. Before discharge from the critical care unit or ED, nurses can help women to identify their risk and plan for safety. Effective nursing care in IPV combines the traditional critical care nursing skills synergistically with provision for the biopsychosocial needs of patients.

Abstract

Background: Prevention of coronary heart disease (CHD) is a primary goal of diabetes management. Unfortunately, CHD risk knowledge is poor among people with diabetes. Purpose: The objective is to determine predictors of CHD risk knowledge in a community sample of people with diabetes. Methods: A total of 678 people with diabetes completed the Heart Disease Facts Questionnaire (HDFQ), a valid and reliable measure of knowledge about the relationship between diabetes and heart disease. Results: In regression analysis with demographics predicting HDFQ scores, sex, annual income, education, and health insurance status predicted HDFQ scores. In a separate regression analysis, having CHD risk factors did not predict HDFQ scores, however, taking medication for CHD risk factors did predict higher HDFQ scores. An analysis of variance showed significant differences between ethnic groups for HDFQ scores; Whites (M = 20.9) showed more CHD risk knowledge than African Americans (M = 19.6), who in turn showed more than Latinos (M = 18.2). Asians scored near Whites (M = 20.4) but did not differ significantly from any other group. Controlling for numerous demographic, socioeconomic, health care, diabetes, and cardiovascular health variables, the magnitude of ethnic differences was attenuated, but persisted. Conclusion: Education regarding modifiable risk factors must be delivered in a timely fashion so that lifestyle modification can be implemented and evaluated before pharmacotherapy is deemed necessary. African Americans and Latinos with diabetes are in the greatest need of education regarding CHD risk.

Abstract

The current study examined the combined moderating effects of cognitive ability and social support on the relation between race-related stress and quality of life in a sample of Black Americans. Participants (N = 323) were administered the Wonderlic Personnel Test (WPT; E. F. Wonderlic Associates, Inc., 1983), the Multidimensional Social Support Scale (MDSS; Winefield, Winefield, & Tiggemann, 1992), the Index of Race-Related Stress-Brief (Utsey, 1999), and the WHOQOL-BREF (The WHO Group, 1998). The findings indicated that cognitive ability and social support, conjointly, moderated the relation between individual and cultural race-related stress and quality of life for Black Americans in the current sample. The paper concludes by discussing the study's findings, limitations, and by offering recommendations for future research related to this area of inquiry.
