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

Findings from several studies suggest that oncology patients undergoing active treatment experience multiple symptoms, and that these symptoms can have a negative effect on patient outcomes. However, no systematic review has summarized the findings from studies that assessed multiple symptoms in these patients. Therefore, the purposes of this review were to: 1) compare and contrast the characteristics of the three most commonly used instruments to measure multiple symptoms; 2) summarize the prevalence rates for multiple symptoms in studies of oncology patients receiving active treatment; 3) describe the relationships among selected demographic, disease, and treatment characteristics and multiple symptoms; and 4) describe the relationships between the occurrence of multiple symptoms and patient outcomes (i.e., functional status, quality of life). Only 18 studies were found that met the inclusion criteria for this review. The majority of the studies were cross-sectional with sample sizes that ranged from 26 to 527. Approximately 40% of patients experienced more than one symptom. However, little is known about the relationships between demographic and clinical characteristics and the occurrence of multiple symptoms. Findings from this review suggest that the occurrence of multiple symptoms is associated with decreased functional status and quality of life. However, given the large number of oncology patients who undergo active treatment each year, additional research is warranted on the prevalence and impact of multiple symptoms. Only when this descriptive research is completed with homogenous samples of patients in terms of cancer diagnoses and treatments can intervention studies for multiple symptoms be developed and tested.

Abstract

Abusive head trauma (AHT) has greater mortality and morbidity than any other form of physical abuse. Therefore, early recognition and accurate diagnosis are essential for comprehensive investigation and appropriate treatment of infants who present with this devastating traumatic injury. Advanced practice nurses need to have a thorough understanding of AHT in order to promptly and accurately assess and manage these infants. Using a case-based approach, the epidemiology, pathophysiology, mechanisms of injury, clinical presentation, diagnosis, and treatment of AHT are described. This article also discusses AHT prevention and implications for advanced practice nurses caring for these patients.

Abstract

The purpose of this descriptive phenomenological study was to describe homeless adolescent mothers' experiences of caring for their children while living in a shelter. Eight homeless adolescent mothers participated in the study. Data were analyzed using Colaizzi [Colaizzi, P. (1978). Psychological research as the phenomenologist views it. In R. S. Valle & M. King (Eds.) Existential Foundations of Psychology (chapter 3). New York, NY: Oxford University Press]. Five themes were generated: (a) tough and troubling times, (b) acting out, (c) wishing it undone, (d) hostile encounters, and (e) steering clear. Nurses working with homeless families may help these young mothers cope with the demands of shelter living while keeping in mind that distinctive support needs may arise during different times of the homeless experience.

Abstract

BACKGROUND:: The Self-care of Heart Failure Index (SCHFI) is a measure of self-care defined as a naturalistic decision-making process involving the choice of behaviors that maintain physiological stability (maintenance) and the response to symptoms when they occur (management). In the 5 years since the SCHFI was published, we have added items, refined the response format of the maintenance scale and the SCHFI scoring procedure, and modified our advice about how to use the scores. OBJECTIVE:: The objective of this article was to update users on these changes. METHODS:: In this article, we address 8 specific questions about reliability, item difficulty, frequency of administration, learning effects, social desirability, validity, judgments of self-care adequacy, clinically relevant change, and comparability of the various versions. RESULTS:: The addition of items to the self-care maintenance scale did not significantly change the coefficient α, providing evidence that the structure of the instrument is more powerful than the individual items. No learning effect is associated with repeated administration. Social desirability is minimal. More evidence is provided of the validity of the SCHFI. A score of 70 or greater can be used as the cut-point to judge self-care adequacy, although evidence is provided that benefit occurs at even lower levels of self-care. A change in a scale score more than one-half of an SD is considered clinically relevant. Because of the standardized scores, results obtained with prior versions can be compared with those from later versions. CONCLUSION:: The SCHFI v.6 is ready to be used by investigators. By publication in this format, we are putting the instrument in the public domain; permission is not required to use the SCHFI. 2009 Lippincott Williams & Wilkins.

Abstract

Forced sex is a public health issue affecting many college women. Despite physical and mental health consequences, and multiple prevention programs on college campuses, most sexual violence goes unreported (Fisher, Daigle, Cullen, & Turner, 2003). The purpose of this research was to determine the significant attitudes and beliefs that are associated with reporting of forced sexual experiences. Guided by the Theory of Planned Behavior (TPB), the study used a predictive exploratory design to explore the association of intention to report forced sex with attitudes and beliefs (Ajzen, 1991). A convenience sample of 144 African-American women who were attending a private college in the south completed a survey. Women who expressed more favorable attitudes towards reporting, perceived reporting as being supported by important referents, and perceived more control over reporting, reported stronger intentions to report forced sex. The analysis supported the utility of TPB in predicting the intention to report forced sex by African-American college women. Theoretically significant and clinically relevant prevention strategies should incorporate important referents, address salient beliefs, and determine ways to increase perceived behavioral control.

Abstract

Objectives: To investigate the arachidonate 5-lipoxygenase-activating protein (ALOX5AP) gene as a potential modifier gene for coronary heart disease (CHD) in patients with familial hypercholesterolemia (FH). Background: The ALOX5AP gene is required for the synthesis of leukotrienes, a protein family involved in inflammatory responses. Recently, genetic variation in this gene was shown to be associated with myocardial infarction in an Icelandic and British population. Since FH is characterized by severely increased levels of plasma low-density lipoprotein (LDL) cholesterol levels, chronic inflammation of the arterial wall, and subsequent premature CHD, the ALOX5AP gene could be an important modifier gene for CHD in FH. Methods: In a cohort of 1817 FH patients, we reconstructed two four-marker haplotypes, previously defined in Icelandic (HapA) and British (HapB) individuals. The haplotypes were inferred with PHASE and the associations between the haplotypes and CHD were analyzed with a Cox proportional hazards model, adjusted for year of birth, sex, and smoking. Results: HapB had a frequency of 6.9% and 8.2% in the group without and with CHD, respectively, conferring a hazard ratio of 1.48 (95% CI 1.17-1.89, p = 0.001). This association was predominantly found in patients with LDL cholesterol levels above the median (HR 1.82, 95% CI 1.20-2.76, p = 0.005). HapA was not associated with CHD. Conclusion: We conclude that genetic variation in the ALOX5AP gene contributes to CHD risk in patients with FH. Our findings emphasize the important role of inflammation in the pathogenesis of early CHD in this disorder, particularly in patients with more severely raised LDL cholesterol levels.

Abstract

Objective: Heart failure (HF) self-care requires both knowledge and skill, but little attention has been given to identify how to improve skill in HF self-care. The objective was to assess what self-care skills patients with HF perceive that they need and how they developed the skills needed to perform self-care. Methods: Data from 85 adults with chronic HF enrolled in 3 prior studies were analyzed using qualitative descriptive meta-analysis techniques. Themes were reexamined using within study and across-study analyses and translated to create a broader and more complete understanding of the development of skill in HF self-care. Results: Tactical and situational skills are needed to perform adequate self-care. Skill in self-care evolves over time and with practice as patients learn how to make self-care practices fit into their daily lives. Proficiency in these skills was acquired primarily through input from family and friends. Health care professionals rarely made significant contributions to the learning of essential skills. Conclusion: Traditional patient education does not support self-care skill development in patients with HF. New patient teaching strategies are needed that support the development of tactical and situational skills, foster coherence, and use trusted resources. Research testing coaching interventions that target skill-building tactics, such as role-playing in specific situations, are needed.

Abstract

Objective: To evaluate the relationships between the amount and type of dietary fat and intermediate age-related macular degeneration (AMD). Design: Women aged 50 to 79 years with high and low lutein intake from 3 sites of the Women's Health Initiative Observational Study were recruited into the Carotenoids in Age-Related Eye Disease Study. Fat intake from 1994 through 1998 was estimated using food frequency questionnaires, and AMD was assessed photographically from 2001 through 2004. Results: Intakes of ω-6 and ω-3 polyunsaturated fatty acids, which were highly correlated (r=0.8), were associated with approximately 2-fold higher prevalence of intermediate AMD in high vs low quintiles. However, monounsaturated fatty acid intake was associated with lower prevalence. Age interactions were often observed. In women younger than 75 years (n=1325), total fat and saturated fatty acid intakes were associated with increased prevalence of AMD (multivariate adjusted odds ratios [95% confidence interval] for intermediate AMD, 1.7 [1.0-2.7] for quintile 5 vs quintile 1 for total fat [P=.10 for trend] and 1.6 [0.7-3.6] for saturated fatty acids [P=.23 for trend]). The associations were reversed in older women. Conclusions: These results support a growing body of evidence suggesting that diets high in several types of fat may contribute to the risk of intermediate AMD and that diets high in monounsaturated fatty acids may be protective.

Abstract

Background: Transforming growth factor ß (TGFß) signaling has been shown to promote myocardial fibrosis and remodeling with coronary artery disease (CAD), and previous studies show a major role for fibrosis in the initiation of malignant ventricular arrhythmias (VA) and sudden cardiac arrest (SCA). Common single nucleotide polymorphisms (SNPs) in TGFß pathway genes may be associated with SCA. Objective: We examined the association of common SNPs among 12 candidate genes in the TGFß pathway with the risk of SCA. Methods: SNPs (n = 617) were genotyped in a case-control study comparing 89 patients with CAD and SCA caused by VA to 520 healthy control subjects. Results: Nineteen SNPs among 5 genes (TGFB2, TGFBR2, SMAD1, SMAD3, SMAD6) were associated with SCA after adjustment for age and sex. After permutation analysis to account for multiple testing, a single SNP in TGFBR2 (rs9838682) was associated with SCA (odds ratio: 1.66, 95% confidence interval: 1.08 to 2.54, P = .02). Conclusion: We show an association between a common TGFBR2 polymorphism and risk of SCA caused by VA in the setting of CAD. If validated, these findings support the role of genetic variation in TGFß signaling in SCA susceptibility.

Abstract

Purpose:To examine perceptions about aging well in the context of cognitive health among a large and diverse group of older adults.Design and Methods:Forty-two focus groups were conducted with older adults living in the community (N = 396; White, African American, American Indian, Chinese, Vietnamese, and Hispanic). Participant descriptions of "someone who you think is aging well" were analyzed. Constant comparison methods examined themes by race/ethnicity.Results:There were notable race/ethnicity differences in perceptions of aging well. Compared with other racial/ethnic groups Chinese participants were more likely to emphasize relationships between mental outlook and physical abilities, Vietnamese participants were less likely to emphasize independent living. American Indians did not relate aging well to diet or physical activity. Important themes that emerged about aging well for all racial/ethnic groups were as follows: living to advanced age, having good physical health, having a positive mental outlook, being cognitively alert, having a good memory, and being socially involved.Implications:To promote cognitive health among diverse populations, communication strategies should focus on shared perceptions of aging well, such as living to an advanced age with intact cognitive function, having a positive attitude, and being mobile. Health promotions may also create a range of culturally sensitive messages, targeted to views that are more salient among some racial/ethnic groups.

Abstract

Context Coronary artery disease (CAD) is the major cause of mortality and morbidity in patients with type 2 diabetes. But the utility of screening patients with type 2 diabetes for asymptomatic CAD is controversial. Objective To assess whether routine screening for CAD identifies patients with type 2 diabetes as being at high cardiac risk and whether it affects their cardiac outcomes. Design, Setting, and Patients The Detection of Ischemia in Asymptomatic Diabetics (DIAD) study is a randomized controlled trial in which 1123 participants with type 2 diabetes and no symptoms of CAD were randomly assigned to be screened with adenosine-stress radionuclide myocardial perfusion imaging (MPI) or not to be screened. Participants were recruited from diabetes clinics and practices and prospectively followed up from August 2000 to September 2007. Main Outcome Measure Cardiac death or nonfatal myocardial infarction (MI). Results The cumulative cardiac event rate was 2.9% over a mean (SD) follow-up of 4.8 (0.9) years for an average of 0.6% per year. Seven nonfatal MIs and 8 cardiac deaths (2.7%) occurred among the screened group and 10 nonfatal MIs and 7 cardiac deaths (3.0%) among the not-screened group (hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.44-1.88; P=.73). Of those in the screened group, 409 participants with normal results and 50 with small MPI defects had lower event rates than the 33 with moderate or large MPI defects; 0.4% per year vs 2.4% per year (HR, 6.3; 95% CI, 1.9-20.1; P=.001). Nevertheless, the positive predictive value of having moderate or large MPI defects was only 12%. The overall rate of coronary revascularization was low in both groups: 31 (5.5%) in the screened group and 44 (7.8%) in the unscreened group (HR, 0.71; 95% CI, 0.45-1.1; P=.14). During the course of study there was a significant and equivalent increase in primary medical prevention in both groups. Conclusion In this contemporary study population of patients with diabetes, the cardiac event rates were low and were not significantly reduced by MPI screening for myocardial ischemia over 4.8 years.

Abstract

Goals of work: The goals of the study were to determine the occurrence rates for and the severity of symptoms at the middle, end, and 1 month after the completion of radiation therapy (RT), to determine the number and types of symptom clusters at these three time points, and to evaluate for changes over time in these symptom clusters. Materials and methods: Symptom occurrence and severity were evaluated using the Memorial Symptom Assessment Scale (MSAS) in a sample of patients (n∈=∈160) who underwent RT for breast or prostate cancer. At each time point, an exploratory factor analysis was done to determine the number of symptom clusters (i.e., symptom factors) based on the MSAS symptom severity ratings. Main results: The majority of the patients were male and married with a mean age of 61.1 years. The five symptoms with the highest occurrence rates across all three time points were lack of energy, pain, difficulty sleeping, feeling drowsy, and sweats. Although the number of symptoms and the specific symptoms within each symptom cluster were not identical across the three time points, three relatively similar symptom clusters (i.e., "mood-cognitive" symptom cluster, "sickness-behavior" symptom cluster, "treatment-related", or "pain" symptom cluster) were identified in this sample. The internal consistency coefficients for the mood-cognitive symptom cluster and sickness-behavior symptom cluster were adequate at ≥ 0.68. Conclusions: Three relatively stable symptom clusters were found across RT. The majority of the symptom cluster severity scores were significantly higher in patients with breast cancer compared to patients with prostate cancer.

Abstract

Purpose: To describe how nurses would respond in common clinical situations involving disagreement with physician colleagues during labor and birth. Study Design and Methods: An electronic survey, consisting of five clinical disagreement case scenarios along with two open-ended questions regarding how to promote effective interdisciplinary communication and collaboration, was administered via a secure Web site. Seven hundred four obstetric nurses in a mid-size metropolitan area were invited to participate via mail. One hundred thirty-three nurses responded. Data were analyzed using descriptive statistics and thematic analysis of open-ended text responses. Results: Respondents were primarily aged ≥40, experienced in labor nursing, and held a BSN; 35% were members of the Association of Women's Health, Obstetric and Neonatal Nurses, 35% were certified in electronic fetal monitoring, and 33% were certified in inpatient obstetrics. In all five scenarios, most nurses were aware of current evidence and published standards of care (range 52%-86%). However, there was a wide discrepancy between current evidence/standards and what nurses indicated would occur in actual clinical practice. Clinical Implications: In this well-educated and knowledgeable sample of experienced labor nurses, reports of what would occur in clinical practice did not match current evidence or standards of care. Adequate nursing knowledge may not be an accurate predictor of appropriate clinical practice. Confidence in administrative support appears to be one of the key factors in empowering nurses to pursue resolution of disagreements in patients' best interests, whereas medical hierarchy, fear, and intimidation are significant barriers.

Abstract

Concurrent sexual partnerships may help to explain the disproportionately high prevalence of HIV and other sexually transmitted infections among African Americans. The persistence of such disparities would also require strong assortative mixing by race. We examined descriptive evidence from 4 nationally representative US surveys and found consistent support for both elements of this hypothesis. Using a data-driven network simulation model, we found that the levels of concurrency and assortative mixing observed produced a 2.6-fold racial disparity in the epidemic potential among young African American adults.

Abstract

Nurse-managed health centers (NMHCs) play an important role in delivering health care services to a wide range of communities and often serve as our nation's safety net providers. Unfortunately, NMHCs struggle to remain in business for a variety of reasons, including underdeveloped business practices. Until now, NMHCs had only data from the Centers for Medicare and Medicaid Services and the Medical Group Management Assocation for comparison with coding patterns in individual centers. This article is the first published report of national data for NMHCs that is available for comparison. Providers need to possess financial acumen to remain open for business. Assessment of CPT coding patterns is a key strategy to support long-term sustainability.

Abstract

Aims: To compare insulin sensitivity (Si) in adults at risk for type 2 diabetes (T2DM) who were categorized as non-depressed, treated for depression and untreated depression after controlling for physical activity (PA). Methods: Baseline data was analyzed from individuals enrolled in a diabetes prevention program (n = 56). Si was calculated using the whole-body insulin sensitivity method. The Centers for Epidemiologic Studies Depression Scale (CESD) was used to assess depressive symptoms and depressed cases were identified using a cutoff of ≥16. Depression treatment was identified using a self-report form validated by medical chart review. The PA subscale of the Health Promoting Lifestyle Profile was used to determine PA levels. Results: One third of participants had elevated depressive symptoms; 19% were taking antidepressant medication. Mean Si was 3.1 (±1.9). In ANOVA, depressed individuals showed significantly lower Si (M = 1.8 ± 0.9) than non-depressed individuals (M = 3.4 ± 1.8). However, individuals taking antidepressant medications had Si similar to non-depressed individuals (M = 3.7 ± 2.3: p = .63). In ANCOVA this association remained after controlling for PA. Conclusions: These data suggest that in adults at high risk for T2DM, depression treatment may improve insulin resistance observed in depression. Healthcare practitioners are encouraged to screen, treat, or refer their patients with depression for treatment.

Abstract

The authors describe the development and incorporation of an integrative therapies subspecialty curriculum into a graduate nursing education program. Specialized education in integrative therapies prepares nursing students more thoroughly for primary care practice because many patients now use what is called complementary and alternative medicine in conjunction with standard medical care. Students learn to determine the safety, efficacy, and cultural significance of complementary and alternative medicine practices of their diverse patient population.

Abstract

Introduction: Descriptive study compared adolescent mothers' subjective perceptions of their children's development with objective developmental assessments. Methods: A volunteer sample of mother/child pairs was recruited from an urban high school. Thirty-three mothers completed the Ages and Stages Questionnaire (A&SQ). The Bayley Scales of Infant Development (BSID) was administered to children. Results: On the BSID, group mean scores all fell within the normal range. However, almost 20% of individual children had one or more delays. Almost 73% of mothers accurately assessed their children's development on the A&SQ when compared with BSID results. Eighteen percent of mothers suspected delays when no delays were objectively identified. A single mother identified delay in a different domain than that identified on the BSID. Discussion: Findings that almost 20% of these children had developmental delays support other research that children of adolescent mothers are at risk for delays. Findings that teen mothers varied in their abilities to assess their children's development reinforce the need for education of teen mothers about child development. Further study is needed to determine the best models of this education in school and community settings.

Abstract

PURPOSE/OBJECTIVES: To assess the degree to which postsurgical adjustment in patients with breast cancer and their partners depends on the nature of the patient-partner dyad relationship. DESIGN: Secondary data analysis from a randomized controlled trial. SETTING: Three cancer centers and one suburban community hospital in New York. SAMPLE: 205 patient-partner dyads (112 intimate-partner, 58 family-member, and 35 nonfamily-member dyads). METHODS: Mann-Whitney nonparametric comparisons and chi-square tests were used to assess dyad types on continuous and categorical variables, and a mixed model for repeated measures compared postsurgical adjustment among dyad types. MAIN RESEARCH VARIABLES: Type of patient-partner dyads and physical, emotional, and social adjustment. FINDINGS: Patients in intimate-partner dyads were younger, had greater incomes, and discovered the lump by routine mammogram as compared to family- or nonfamily-member dyads. No significant differences were observed in patients' physical or emotional adjustment. Patients with intimate partners had greater difficulty in their social and domestic environments. Partners in intimate-partner dyads had lower scores on psychological well-being, more problems in social and domestic adjustment, and less social support to promote social adjustment. CONCLUSIONS: Women with breast cancer experience successful physical and emotional adjustment whether they have intimate-partner, family-member, or nonfamily-member partners. Intimate partners are at greater risk for emotional and social adjustment issues. IMPLICATIONS FOR NURSING: When designing interventions, consideration must be given to the type of patient-partner dyad involved.
