Abstract

Fatigue has been associated with inflammation and cytokine activity among adults, but this relationship has not been evaluated among adults living with HIV. Diurnal patterns of fatigue have been previously identified in adults with HIV/AIDS. Thus, the purpose of this study was to describe these fatigue patterns in relation to cytokine plasma concentrations and gene polymorphisms. A convenience sample of 317 adults living with HIV/AIDS completed a measure of fatigue in the morning and evening for three consecutive days; participants reporting low levels of both morning and evening fatigue (n= 110) or high levels of fatigue in the morning and evening (n= 114) were included in the analysis, resulting in a final sample of 224 adults (151 men, 55 women, and 18 transgender). Plasma cytokines were analyzed, and genotyping was conducted for 15 candidate genes involved in cytokine signaling: interferon-gamma (IFNG), IFNG receptor 1 (IFNGR1), interleukins (IL), nuclear factor of kappa light polypeptide gene enhancer in B cells (NFKB-1 and -2), and tumor necrosis factor alpha (TNFA). Demographic and clinical variables were evaluated as potential covariates. Controlling for genomic estimates of ancestry and self-reported race/ethnicity and gender, the high fatigue pattern was associated with five single nucleotide polymorphisms (SNPs): IL1B rs1071676 and rs1143627, IL4 rs2243274, and TNFA rs1800683 and rs1041981. The IL1B and TNFA polymorphisms were not associated with plasma levels of IL-1β or TNFα, respectively. This study strengthens the evidence for an association between inflammation and fatigue. In this chronic illness population, the cytokine polymorphisms associated with high levels of morning and evening fatigue provide direction for future personalized medicine intervention research.

Abstract

Study Objectives: Cytokine activity and polymorphisms have been associated with sleep outcomes in prior animal and human research. The purpose of this study was to determine whether circulating plasma cytokines and cytokine polymorphisms are associated with the poor sleep maintenance commonly experienced by adults living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Design: Cross-sectional descriptive study. Setting: HIV clinics and community sites in the San Francisco Bay area. Participants: A convenience sample of 289 adults (193 men, 73 women, and 23 transgender) living with HIV/AIDS. Interventions: None. Measurements and Results: A wrist actigraph was worn for 72 h to estimate the percentage of wake after sleep onset (WASO%) and total sleep time (TST), plasma cytokines were analyzed, and genotyping was conducted for 15 candidate genes involved in cytokine signaling: interferongamma (IFNG), IFNG receptor 1 (IFNGR1), interleukins (IL1B, IL1R2, IL1R2, IL2, IL4, IL6, IL8, IL10, IL13, IL17A), nuclear factor of kappa light polypeptide gene enhancer in B cells (NFKB1 and NFKB2), and tumor necrosis factor-alpha (TNFA). Controlling for demographic variables such as race and sex, and clinical variables such as CD4+ count and medications, higher WASO% was associated with single nucleotide polymorphisms (SNPs) of IL1R2 rs11674595 and TNFA rs1041981 and less WASO% was associated with IL2 rs2069776. IL1R2 rs11674595 and TNFA rs1041981 were also associated with short sleep duration. Conclusions: This study strengthens the evidence for an association between inflammation and sleep maintenance problems. In this chronic illness population, cytokine polymorphisms associated with wake after sleep onset provide direction for intervention research aimed at comparing anti-inflammatory mechanisms with hypnotic agents for improving sleep maintenance and total sleep time.

Abstract

Varied diets are diverse with respect to diet quality, and existing dietary variety indices do not capture this heterogeneity. We developed and evaluated the multidimensional US Healthy Food Diversity (HFD) index, which measures dietary variety, dietary quality and proportionality according to the 2010 Dietary Guidelines for Americans (DGA). In the present study, two 24 h dietary recalls from the 2003-6 National Health and Nutrition Examination Survey (NHANES) were used to estimate the intake of twenty-six food groups and health weights for each food group were informed by the 2010 DGA. The US HFD index can range between 0 (poor) and 1 - 1/n, where n is the number of foods; the score is maximised by consuming a variety of foods in proportions recommended by the 2010 DGA. Energy-adjusted Pearson's correlations were computed between the US HFD index and each food group and the probability of adequacy for fifteen nutrients. Linear regression was run to test whether the index differentiated between subpopulations with differences in dietary quality commonly reported in the literature. The observed mean index score was 0·36, indicating that participants did not consume a variety of healthful foods. The index positively correlated with nutrient-dense foods including whole grains, fruits, orange vegetables and low-fat dairy (r 0·12 to 0·64) and negatively correlated with added sugars and lean meats (r - 0·14 to - 0·23). The index also positively correlated with the mean probability of nutrient adequacy (r 0·41; P< 0·0001) and identified non-smokers, women and older adults as subpopulations with better dietary qualities. The US HFD index may be used to inform national dietary guidance and investigate whether healthful dietary variety promotes weight control.

Abstract

Context The relatively low number of older patients in cancer trials limits knowledge of how older adults experience symptoms associated with cancer and its treatment. Objectives This study evaluated for differences in the symptom experience across four older age groups (60-64, 65-69, 70-74, 75 years). Methods Demographic, clinical, and symptom data from 330 patients aged >60 years who participated in one Australian and two U.S. studies were evaluated. The Memorial Symptom Assessment Scale was used to evaluate the occurrence, severity, frequency, and distress of 32 symptoms commonly associated with cancer and its treatment. Results On average, regardless of the age group, patients reported 10 concurrent symptoms. The most prevalent symptoms were physical in nature. Worrying was the most common psychological symptom. For 28 (87.5%) of the 32 Memorial Symptom Assessment Scale symptoms, no age-related differences were found in symptom occurrence rates. For symptom severity ratings, an age-related trend was found for difficulty swallowing. As age increased, severity of difficulty swallowing decreased. For symptom frequency, age-related trends were found for feeling irritable and diarrhea, with both decreasing in frequency as age increased. For symptom distress, age-related trends were found for lack of energy, shortness of breath, feeling bloated, and difficulty swallowing. As age increased, these symptoms received lower average distress ratings. Conclusion Additional research is warranted to examine how age differences in symptom experience are influenced by treatment differences, aging-related changes in biological or psychological processes, or age-related response shift.

Abstract

BACKGROUND A large amount of interindividual variability exists in the occurrence of symptoms in patients receiving chemotherapy (CTX). The purposes of the current study, which was performed in a sample of 582 oncology outpatients who were receiving CTX, were to identify subgroups of patients based on their distinct experiences with 25 commonly occurring symptoms and to identify demographic and clinical characteristics associated with subgroup membership. In addition, differences in quality of life outcomes were evaluated. METHODS Oncology outpatients with breast, gastrointestinal, gynecological, or lung cancer completed the Memorial Symptom Assessment Scale before their next cycle of CTX. Latent class analysis was used to identify subgroups of patients with distinct symptom experiences. RESULTS Three distinct subgroups of patients were identified (ie, 36.1% in Low class; 50.0% in Moderate class, and 13.9% in All High class). Patients in the All High class were significantly younger and more likely to be female and nonwhite, and had lower levels of social support, lower socioeconomic status, poorer functional status, and a higher level of comorbidity. CONCLUSIONS Findings from the current study support the clinical observation that some oncology patients experience a differentially higher symptom burden during CTX. These high-risk patients experience significant decrements in quality of life.

Abstract

Adolescents may come from family settings that heighten their vulnerability to early sexual initiation, promiscuity and sexual exploitation. Using qualitative data, we illustrated how early life and family circumstances including neglectful or dysfunctional parenting, sexual abuse, and unstable housing placed young women on a risk trajectory for HIV infection. Five representative cases from a sample of 26 adolescent and young adult HIV-infected females (ages 16-24) who participated in a study about the disease-related adaptive challenges they faced are discussed. Study participants were recruited from five New York City adolescent HIV clinics that provided comprehensive specialty medical and ancillary social services to adolescents and young adults with the disease. The findings revealed that these young women’s unmet need for love, protection, and feeling valued left them vulnerable to exploitive relationships with men who were often significantly older and resulted in their HIV infection.

Abstract

Objective This study aims to evaluate the relationship between early-onset severe preeclampsia and first trimester serum levels of pregnancy-associated plasma protein A (PAPP-A) and total human chorionic gonadotropin (hCG). Study Design The association between early-onset severe preeclampsia and abnormal levels of first trimester PAPP-A and total hCG in maternal serum were measured in a sample of singleton pregnancies without chromosomal defects that had integrated prenatal serum screening in 2009 and 2010 (n = 129,488). Logistic binomial regression was used to estimate the relative risk (RR) of early-onset severe preeclampsia in pregnancies with abnormal levels of first trimester PAPP-A or total hCG as compared with controls. Results Regardless of parity, women with low first trimester PAPP-A or high total hCG were at increased risk for early-onset severe preeclampsia. Women with low PAPP-A (multiple of the median [MoM] ≤ the 10th percentile in nulliparous or ≤ the 5th percentile in multiparous) or high total hCG (MoM ≥ the 90th percentile in nulliparous or ≥ the 95th percentile in multiparous) were at more than a threefold increased risk for early-onset severe preeclampsia (RR, 4.2; 95% confidence interval [CI], 3.0-5.9 and RR, 3.3; 95% CI, 2.1-5.2, respectively). Conclusion Routinely collected first trimester measurements of PAPP-A and total hCG provide unique risk information for early-onset severe preeclampsia.

Abstract

Objective. To investigate the clinical effectiveness and costs of nurses working as substitutes for physicians in primary care. Design. Systematic review and meta-analysis of published randomized controlled trials (RCTs) and 2 economic studies that compared nurse-led care with care by primary care physicians on numerous variables, including satisfaction, hospital admission, mortality, and costs of health care. Settings and participants. The 24 RCTs were drawn from 5 different countries (UK, Netherlands, USA, Russia, and South Africa). In total, there were 38, 974 participants. Eleven of the studies had less than 200 participants and 13 studies had more than 200 (median, 1624). Mean age was reported in 20 trials and ranged from 10 to 83 years. Analysis. The authors assessed risk of bias in the studies, calculated the study-specific and pooled relative risks (RR) or standardized mean differences (SMD), and performed fixed-effects meta-analyses. Main results. Nurse-led care was effective at reducing the overall risk of hospital admission (RR 0.76, 95% CI 0.64-0.91) and mortality (RR 0.89, 95% CI 0.84-0.96) in RCTs of ongoing or non-urgent care, longer (at least 12 months) follow-up episodes, and in in larger (n > 200) RCTs. Pooled analysis showed higher overall scores of patient satisfaction with nurse led care (SMD 0.18, 95% Cl 0.13-0.23). Higher-quality RCTs (with better allocation concealment and less attrition) showed higher rates of hospital admissions and mortality with nurse-led care, but the difference was not significant. Subgroup analysis showed that RNs had a stronger effect than nurse practitioners (NPs) on patient satisfaction. The results of cost-effectiveness and improved quality of care analysis with nurses were inconclusive. Conclusion. Nurse-led care appears to have a positive effect on patient care and outcomes but more rigorous research is needed to confirm these findings.

Abstract

Background: While the human immunodeficiency virus (HIV) incidence rate has remained steady in most groups, the overall incidence of HIV among men who have sex with men (MSM) has been steadily increasing in the United States. eHealth is a platform for health behavior change interventions and provides new opportunities for the delivery of HIV prevention messages. Objective: The purpose of this systematic review was to examine the use of eHealth interventions for HIV prevention in high-risk MSM. Methods: We systematically searched PubMed, OVID, ISI Web of Knowledge, Google Scholar, and Google for articles and grey literature reporting the original results of any studies related to HIV prevention in MSM and developed a standard data collection form to extract information on study characteristics and outcome data. Results: In total, 13 articles met the inclusion criteria, of which five articles targeted HIV testing behaviors and eight focused on decreasing HIV risk behaviors. Interventions included Web-based education modules, text messaging (SMS, short message service), chat rooms, and social networking. The methodological quality of articles ranged from 49.4-94.6%. Wide variation in the interventions meant synthesis of the results using meta-analysis would not be appropriate. Conclusions: This review shows evidence that eHealth for HIV prevention in high-risk MSM has the potential to be effective in the short term for reducing HIV risk behaviors and increasing testing rates. Given that many of these studies were short term and had other limitations, but showed strong preliminary evidence of improving outcomes, additional work needs to rigorously assess the use of eHealth strategies for HIV prevention in high-risk MSM.

Abstract

Objective. To determine if there is an association between self-reported English language ability and glycemic control in Latinos with type 2 diabetes. Design. Descriptive correlational study using data from a larger cross-sectional study. Setting and participants. 167 adults with diabetes who selfidentified as Latino or Hispanic recruited at clinics in the Chicago area from May 2004 to May 2006. The dataset was collected using face-to-face interviews with diabetic patients aged ≥ 18 years. All participants attended clinics affiliated with an academic medical center or physician offices affiliated with a suburban hospital. Patients with type 1 diabetes and those with < 17 points on the Mini-Mental State Examination were excluded. English speaking ability was categorized as speaking English "not at all," "not well," "well," or "very well" based on patient self-report. A multivariable logistic regression model was used to examine the predictive relationship between English language skills and HbA1c levels, with covariates selected if they were significantly correlated with English language ability. The final regression model accounted for age, sex, education, annual income, health insurance status, duration of diabetes, birth in the United States, and years in the United States. Main outcome measure. HbA1c ≥ 7.0% as captured by chart review. Main results. Of the 167 patients, 38% reported speaking English very well, 21% reported speaking well, 26% reported speaking not very well, and 14% did not speak English at all. Reflecting immigration-sensitive patterns, patients who spoke English very well were younger and more likely to have graduated high school and have an annual income over $25,000 per year. Comorbidities and complications did not differ by English speaking ability except for diabetic eye disease, which was was more prevalent among those who did not speak English at all (42%, p = 0.04). Whether speaking ability was treated as a continuous or dichotomous variable, HbA1c levels formed a U-shaped curve: those who spoke English very well (odds ratio [OR] 2.32, 95% CI, 1.00-5.41) or not at all (OR 4.11, 95% CI 1.35-12.54) had higher odds of having an elevated HbA1c than those who spoke English well, although this was only statistically significant for those who spoke no English. In adjusted analyses, the U-shaped curve persisted with the highest odds among those who spoke English very well (OR 3.20, 95% CI 1.05-9.79) or not at all (OR 4.95, 95% CI 1.29-18.92). Conclusion. The relationship between English speaking ability and diabetes management is more complex than previously described. Interventions aimed at improving diabetes outcomes may need to be tailored to specific subgroups within the Latino population.

Abstract

Purpose: The study evaluates the implementation of a United Nations Children's Fund (UNICEF)/WHO Baby-Friendly Hospital Initiative (BFHI) in a large urban hospital in New York City that serves primarily poor, minority women. Study Design and Methods: A descriptive qualitative evaluation study that included focus groups, key informant interviews, and observations of the clinical environment was conducted using a community-based participatory research approach with healthcare providers. Results: Findings revealed strengths and challenges in the implementation process at the system, provider, and patient levels. Strategies for enhancing program implementation and outcomes include expansion of provider education, development of additional patient interventions, enhancement of environmental structural supports, and continuation and expansion of program evaluation activities. Clinical Implications: Evaluation of program implementation at multiple levels of the organization in collaboration with providers is critical to understanding program outcomes.

Abstract

Purpose/Objectives: To identify latent classes of individuals with distinct quality-of-life (QOL) trajectories, to evaluate for differences in demographic characteristics between the latent classes, and to evaluate for variations in pro- and anti-inflammatory cytokine genes between the latent classes. Design: Descriptive, longitudinal study. Setting: Two radiation therapy departments located in a comprehensive cancer center and a community-based oncology program in northern California. Sample: 168 outpatients with prostate, breast, brain, or lung cancer and 85 of their family caregivers (FCs). Methods: Growth mixture modeling (GMM) was employed to identify latent classes of individuals based on QOL scores measured prior to, during, and for four months following completion of radiation therapy. Single nucleotide polymorphisms (SNPs) and haplotypes in 16 candidate cytokine genes were tested between the latent classes. Logistic regression was used to evaluate the relationships among genotypic and phenotypic characteristics and QOL GMM group membership. Main Research Variables: QOL latent class membership and variations in cytokine genes. Findings: Two latent QOL classes were found: higher and lower. Patients and FCs who were younger, identified with an ethnic minority group, had poorer functional status, or had children living at home were more likely to belong to the lower QOL class. After controlling for significant covariates, between-group differences were found in SNPs in interleukin 1 receptor 2 (IL1R2) and nuclear factor kappa beta 2 (NFKB2). For IL1R2, carrying one or two doses of the rare C allele was associated with decreased odds of belonging to the lower QOL class. For NFKB2, carriers with two doses of the rare G allele were more likely to belong to the lower QOL class. Conclusions: Unique genetic markers in cytokine genes may partially explain interindividual variability in QOL. Implications for Nursing: Determination of high-risk characteristics and unique genetic markers would allow for earlier identification of patients with cancer and FCs at higher risk for poorer QOL. Knowledge of these risk factors could assist in the development of more targeted clinical or supportive care interventions for those identified.

Abstract

The Patient Protection and Affordable Care Act (PPACA, 2010) and the Institute of Medicine's (IOM, 2011) Future of Nursing report have prompted changes in the U.S. health care system. This has also stimulated a new direction of thinking for the profession of nursing. New payment and priority structures, where value is placed ahead of volume in care, will start to define our health system in new and unknown ways for years. One thing we all know for sure: we cannot afford the same inefficient models and systems of care of yesterday any longer. The Data-Driven Model for Excellence in Staffing was created as the organizing framework to lead the development of best practices for nurse staffing across the continuum through research and innovation. Regardless of the setting, nurses must integrate multiple concepts with the value of professional nursing to create new care and staffing models. Traditional models demonstrate that nurses are a commodity. If the profession is to make any significant changes in nurse staffing, it is through the articulation of the value of our professional practice within the overall health care environment. This position paper is organized around the concepts from the Data-Driven Model for Excellence in Staffing. The main concepts are: Core Concept 1: Users and Patients of Health Care, Core Concept 2: Providers of Health Care, Core Concept 3: Environment of Care, Core Concept 4: Delivery of Care, Core Concept 5: Quality, Safety, and Outcomes of Care. This position paper provides a comprehensive view of those concepts and components, why those concepts and components are important in this new era of nurse staffing, and a 3-year challenge that will push the nursing profession forward in all settings across the care continuum. There are decades of research supporting various changes to nurse staffing. Yet little has been done to move that research into practice and operations. While the primary goal of this position paper is to generate research and innovative thinking about nurse staffing across all health care settings, a second goal is to stimulate additional publications. This includes a goal of at least 20 articles in Nursing Economic$ on best practices in staffing and care models from across the continuum over the next 3 years.

Abstract

We explored direct and indirect influences of physical work environment on job satisfaction in a nationally representative sample of 1,141 early-career registered nurses. In the fully specified model, physical work environment had a non-significant direct effect on job satisfaction. The path analysis used to test multiple indirect effects showed that physical work environment had a positive indirect effect (p<.05) on job satisfaction through ten variables: negative affectivity, variety, workgroup cohesion, nurse-physician relations, quantitative workload, organizational constraints, distributive justice, promotional opportunity, local and non-local job opportunities. The findings make important contributions to the understanding of the relationship between physical work environment and job satisfaction. The results can inform health care leaders' insight about how physical work environment influences nurses' job satisfaction.

Abstract

Little is known about the nature of interprofessional collaboration on intensive care units (ICUs), despite its recognition as a key component of patient safety and quality improvement initiatives. This comparative ethnographic study addresses this gap in knowledge and explores the different factors that influence collaborative work in the ICU. It aims to develop an empirically grounded team diagnostic tool, and associated interventions to strengthen team-based care and patient family involvement. This iterative study is comprised of three phases: a scoping review, a multi-site ethnographic study in eight ICUs over 2 years; and the development of a diagnostic tool and associated interprofessional intervention-development. This study's multi-site design and the richness and breadth of its data maximize its potential to improve clinical outcomes through an enhanced understanding of interprofessional dynamics and how patient family members in ICU settings are best included in care processes. Our research dissemination strategy, as well as the diagnostic tool and associated educational interventions developed from this study will help transfer the study's findings to other settings.

Abstract

Objective: This study examined gender, ethnicity and psychological factors associated with alcohol problems among Asian American college students, using the CAGE questionnaire. Method: The study is a cross-sectional, school-based survey. College students who self-identified as Asian, participated. Results: The sample comprised 258 Asian American college students (132 men and 126 women). In all, 17.7% of males and 8.9% of females had alcohol problems based on CAGE score of 2 or more; yet, the difference was marginally significant (χ2 [1, N = 225] = 3.7, p = 0.08). Chinese and Vietnamese males tended to have more alcohol problems than females in their respective ethnic subgroups. Among Koreans, more females (33%) had the problems than males (11%). Male students did not differ in alcohol problems by ethnicity, whereas Korean females were more likely to have the problems (χ2 [4, N = 112] = 13.0, p = 0.01) than females in the other groups. After controlling for gender, Asian American college students who were older (≥25), smoking currently and reporting depressed mood were more likely to have alcohol problems. Conclusions: College health center workers should monitor more closely Asian students who have the risk factors for early detection of and treatment for alcohol problems.

Abstract

The rapidly aging population and their frequent use of hospital services will create substantial quality challenges in the near future. Redesigning rural hospital work environments is the key to improving the quality of care for older adults. This study explored how the work environment influences registered nurses' (RNs') perceived quality of geriatric care in rural hospitals. We used an exploratory mixed-methods research design emphasizing the qualitative data (in-depth, semi-structured interviews). Quantitative data (questionnaire) measuring the RN work environment were also collected to augment qualitative data. Four themes emerged: (a) collegial RN relationships, (b) poor staffing/utilization, (c) technology benefits/challenges, and (d) RN-physician interactions, which were identified as key factors influencing the quality of geriatric care. We concluded that rural hospital work environments may not be optimized to facilitate the delivery of quality geriatric care. Targeted interventions are needed to improve overall quality of care for hospitalized older adults in rural settings.

Abstract

Objective. To evaluate the usefulness of the Frailty Index (FI) as a prognostic indicator of adverse outcomes in geriatric trauma patients,. Design. Prospective cohort study. Setting and participants. Geriatric (aged 65 and over) trauma patients admitted to inpatient units at a Level 1 trauma center in Arizona were enrolled. Patients were excluded if they were intubated/nonresponsive with no family members present or transferred from another institution (eg, skilled nursing facility). The following categories of data were collected: (a) patient demographics, (b) type and mechanism of injury, (c) vital signs (eg, Glasgow coma scale score, systolic blood pressure, heart rate, body temperature), (d) need for operative intervention, (e) in-hospital complications, (f) hospital and intensive care unit (ICU) lengths of stay, and (g) discharge disposition. Patients or, in the case of nonresponsive patients, their closest relative, responded to the 50-item Frailty Index questionnaire, which includes questions regarding age, comorbid conditions, medications, activities of daily living (ADLs), social activities, mood, and nutrition. FI score ranges from 0 (non-frail) to 1 (frail), with an FI of 0.25 or more indicative of frailty based on established guidelines. Patients were categorized as frail or non-frail according to their FI scores and were followed during the course of their hospitalization. Main outcome measure. The primary outcome measure was in-hospital complications. In-hospital complications included myocardial infarction, cardiopulmonary arrest, pneumonia, pulmonary embolism, sepsis, urinary tract infection, deep venous thrombosis, disseminated intravascular coagulation, renal insufficiency, and reoperation. The secondary outcome measure was adverse discharge disposition, which was defined as death during the course of hospitalization or discharge to a skilled nursing facility. Main results. The sample consisted of 250 patients with a mean age of 77.9 years. Among these, 44.0% were considered frail. Patients with frailty were more likely to have a higher Injury Severity Score (P = 0.04) and a higher mean FI (P = 0.01) than those without frailty. There were no statistically significant differences with respect to age (P = 0.21), mechanism of injury (P = 0.09), systolic blood pressure (P = 0.30), or Glasgow Coma Scale score (P = 0.91) between the groups. Patients with frailty were more likely to develop in-hospital complications (37.3% vs 21.4%, P = 0.001) than those without frailty. Among these complications, pneumonia and urinary tract infection were the most common. There were no differences in the rate of reoperation (P = 0.54) between the 2 groups. An FI of 0.25 or higher was associated with the development of in-hospital complications (P = 0.001) even after adjusting for age, systolic blood pressure, heart rate, and Injury Severity Score. Frail patients had longer hospital length of stay (P = 0.01) and ICU length of stay (P = 0.01), and were more likely to have adverse discharge disposition (37.3% vs. 12.9%, P = 0.001). All patients who died during the course of hospitalization (n = 5) were considered frail. Frailty was also found to be a predictor of adverse discharge disposition (P = 0.001) after adjustment for age, male sex, Injury Severity Score, and mechanism of injury. Conclusion. The FI is effective in identifying geriatric trauma patients, who are vulnerable to poor health outcomes.

Abstract

Sexual violence is a significant problem on many college campuses. Bystander education programs have been found to train individuals to act to prevent sexual and partner violence and improve the responses of peers to survivors. Limited evidence suggests that gender differences exist between males and females regarding both attitudes toward, and use of, bystander behavior, with females reporting more supportive attitudes and greater use of bystander behavior. The purpose of this study is to compare male and female college students on attitudes toward date rape, bystander efficacy, intention to act as a bystander, and actual use of bystander behaviors. A secondary aimexplored gender differences in theoretically driven bystander behaviors and barriers to acting as a bystander. A convenience sample of 157 full-time undergraduate students aged 18-24 years completed survey measures of attitudes related to sexual and partner violence and willingness to help. Analysis of variance and chi-squarewere used to compare gender differences in scores. Significant gender differences were found for date rape attitudes, efficacy, and intention to act as a positive bystander. Men reportedmore rape-supportive attitudes and greater intention to act as a bystander than women, whereas women reported greater levels of bystander efficacy than men. The findings can be used in tailoring genderspecific components of bystander education programs for sexual assault prevention and intervention.
