Hospital-Based Nursing Research: Clinical and Economic Outcomes

We surveyed 181 nursing research leaders from Magnet® hospitals, using mixed methods with the online Hospital-Based Nursing Research Clinical and Economic Outcomes survey, to describe the clinical and economic outcomes of nursing research conducted in hospital settings. We used descriptive statistics to analyze the quantitative findings and a qualitative descriptive approach to study the open-ended responses. Most respondents reported that findings from their hospital-based studies were implemented on their units (88.2%), improved health care processes (88.2%), and reduced hospital costs (79%). Over 50% reported positive impacts on core quality measures, including improving patient/family satisfaction (76.8%), nurse satisfaction (65%), length of stay (59.1%), and infection rates (56.5%). Four themes were identified: study evaluation, improvements in care delivery/clinical outcomes, economic impact, and intrinsic and extrinsic rewards. Much of the research reported by respondents focused on quality measures with findings that resulted in improved clinical and economic outcomes.

Burnout, Workplace Factors, and Intent to Leave Among Hematology/Oncology Nurse Practitioners

Background

Burnout and intent to leave have been well documented in oncology/hematology health-care professionals, with a potentially detrimental effect on the patient-provider relationship and job satisfaction. With the recommended changes in the nurse practitioner (NP) role to accommodate for the physician shortage, it is important to determine the burnout and intent to leave of hematology/oncology NPs.

Purpose

To examine the association between burnout, workplace factors, and intent to leave among hematology/oncology NPs.

Methods

In this cross-sectional survey, a convenience sample of 201 hematology/oncology NPs was recruited to assess their burnout levels using the Maslach Burnout Inventory, workplace factors using the Areas of Worklife survey (AWS), and intent to leave. Descriptive, correlational, and logistic regression analyses were performed to examine the relationships among variables.

Results

44 (21.9%) participants reported intention to leave the profession or hematology/oncology. 30.8% of the sample reported a high level of emotional exhaustion, 9.0% reported high depersonalization, and 21.0% reported low personal accomplishment. Emotional exhaustion was related to increased likelihood of intent to leave in regression model (adjusted odds ratio [OR] = 1.10, 95% confidence interval [CI] = 1.05–1.17, p < .001). Workplace reward (adjusted OR = 0.4, 95% CI = 0.17–0.93, p < .05) and value (adjusted OR = 0.52, 95% CI = 0.28–0.99, p < .05) were negatively associated with intent to leave.

Conclusion

Hematology/oncology NPs experience high emotional exhaustion, with over 20% indicating intent to leave their job or the nursing profession. Some workplace factors may play protective roles to reduce the intent to leave. Interventions are needed to enhance these workplace factors to decrease burnout.

Development and Preliminary Testing of the Perceived Benefit and Burden Scales for Cancer Clinical Trial Participation

We developed measures of benefits and burdens of research participation in cancer clinical trials using a sequential mixed methods design with a qualitative ( n = 32) and quantitative sample ( n = 110) of cancer clinical trial participants. Benefit-burden items (22 for benefits, 23 for burdens) were subsequently developed and assessed through cognitive interviewing for content, clarity, and meaning. Preliminary psychometric analyses support the internal consistency reliability and construct validity of Benefit (α = .90) and Burden (α = .87) research participation scales. Item response theory models supported the discrimination ability of the items on the scales. Participants who had thoughts of dropping out had lower Benefit scale scores ( p < .001) and higher Burden scores ( p < .001) than those who had no thoughts of dropping out, supporting construct validity. With further psychometric testing, the scale can be used to develop appropriate interventions to address recruitment and retention of human participants in clinical research.

TNF alpha inhibits myogenic differentiation of C2C12 cells through NF-κB activation and impairment of IGF-1 signaling pathway

Cachexia or muscle wasting is a common condition that occurs in many chronic diseases. The wasting conditions are characterized by increased levels of TNF-α which was also known as cachectin in the past. But how TNF-α exerts its cachetic effects remains controversial. To clarify this issue, we investigated the impact of TNF-α on C2C12 cell myogenic differentiation. Our results demonstrate that myotube formation was completely inhibited by TNF-α when added to differentiating C2C12 myoblasts. The inhibitory effect of TNF-α on differentiation was accompanied by activation of NF-κB and down regulation of myogenin and Akt. Importantly, TNF-α's effect on differentiation was abolished when IGF-1 was added to the culture. IGF-1 treatment also inhibited NF-κB reporter activity and restored Akt levels. Our data suggest that TNF-α inhibits myogenic differentiation through NF-κB activation and impairment of IGF-1 signaling pathway. The reversal of TNF-α induced inhibition of myogenesis by IGF-1 may have significant therapeutic potential.

The influences of immigration on health information seeking behaviors among Korean Americans and Native Koreans

Korean Americans (KAs) have low screening rates for cancer and are often not well informed about their chronic diseases. Reduced access to health-related information is one reason for gaps in knowledge and the widening health disparities among minority populations. However, little research exists about KAs' health information seeking behaviors. Guided by the Structural Influence Model, this study examines the influence of immigration status on KAs' trust in health information sources and health information seeking behaviors. Cross-sectional surveys were conducted in the Washington, D.C., metropolitan area as well as in the Gwangju metropolitan city in South Korea during 2006-2007. Two hundred and fifty-four KAs and 208 native Koreans who were 40 years of age or older completed the surveys. When comparing native Koreans to KAs, we found KAs were 3 times more likely to trust health information from newspapers or magazines (odds ratio [OR] = 3.13; 95% confidence interval [CI] = 1.49-6.54) and 11 times more likely to read the health sections of newspapers or magazines (OR = 11.35; 95% CI = 3.92-32.91) in multivariate adjusted models. However, they were less likely to look for health information from TV (OR = 0.29; 95% CI = 0.12-0.72) than native Koreans. Our results indicate that immigration status has profound influences on KAs' health information seeking behaviors. Increasing the availability of reliable and valid health information from printed Korean language magazines or newspapers could have a positive influence on increasing awareness and promoting screening behaviors among KAs.

Breast cancer screening practices among Asian Americans and Pacific Islanders

OBJECTIVE

To compare the breast cancer screening practices and related factors between Asian Americans and Pacific Islanders (PIs) and non-Hispanic whites.

METHODS

Using 2008 Behavioral Risk Factor Surveillance System data, reported mammogram usage among women aged 40+ were compared. Covariates included demographics, risk behaviors, health perception, care access, and general health practice behavior.

RESULTS

PIs had higher rates of screening mammogram usage than did Asian Americans. Most covariates had different levels of influence on mammogram screening for the 2 groups, with a few in opposite directions.

CONCLUSION

Understanding the magnitude and predictors of these disparities for racial/ethnic groups can help inform targeted interventions.

The management of sleep and circadian disturbance in patients with dementia

Sleep and circadian disturbances are common among patients with dementia. Symptomatic manifestations vary according to dementia subtype, with one commonly shared pattern--the irregular sleep-wake rhythm (ISWR), a circadian disorder characterized by an absence of the sleepwake cycle’s circadian synchronization. Hypothesized mechanisms of circadian rhythm disturbance include suprachiasmatic nucleus (SCN) circadian pacemaker damage, pineal gland and melatonin secretion alterations, and reduced zeitbeigers and decreased input to the SCN. Management options include prescribed sleep/wake scheduling, light therapy, melatonin, physical and social activity, and mixed modality. The mixed-modality approach is the most effective method in treating ISWR. Pharmacologic interventions are controversial, with no evidence supporting their effectiveness while associated with multiple side effects. They should be used with caution and only be considered as short-term therapy. All treatment strategies should be individualized to achieve the best outcomes.

Lifestyle behaviors, chronic diseases, and ratings of health between black and white adults with pre-diabetes

PURPOSES

The purposes of this study were to assess differences in lifestyle behaviors and other health-related factors between black and white adults with pre-diabetes and to identify predictors for lifestyle behaviors.

METHODS

Using the 2007 and 2009 data from the Behavioral Risk Factor Surveillance System (BRFSS), an annual cross-sectional survey of randomly selected samples from each state, black (n = 1156) and white (n = 9539) adults with pre-diabetes were compared on lifestyle behaviors, general health practices, perceptions of health, chronic diseases, and access to care. Predictors for participating in regular physical activity and adequate intake of fruits and vegetables were identified for each racial and gender group using multiple regression procedures.

RESULTS

Less than 40% of the adults with pre-diabetes participated in regular physical activity, and less than a quarter had adequate intake of fruits and vegetables; only 20% met the body weight recommendations. Compared to whites, blacks were more likely to be overweight/obese (86% vs 79%) and less likely to engage in regular physical activity (29% vs 40%). Except for adequate intake of fruits and vegetables, each racial and gender group had different predictors for regular physical activity. For black males, the predictors included impaired physical health and coronary heart disease/stroke. For black females, the predictors were younger age and routine checkup.

CONCLUSIONS

Significant disparities exist between blacks and whites in lifestyle behaviors and other health-related factors. Targeted intervention strategies are needed to motivate blacks to modify behaviors to prevent or delay the development of diabetes.

Comparison of lifestyle behaviors and related factors between Asian American and white adults with prediabetes

This study compares lifestyle behaviors and related factors between Asian American and white adults with self-reported prediabetes and identifies covariates/predictors for regular physical activity and adequate intake of fruits/vegetables. Using data from the United States of America Behavioral Risk Factor Surveillance System, 302 Asian Americans and 9558 white adults were analyzed. There were no significant differences for participating in regular physical activity or consumption of adequate fruits/vegetables between the two groups. Overall, 40% of the respondents engaged in regular physical activity, whereas less than 25% reported an adequate intake of fruits/vegetables. In the adjusted models, compared to white, Asian Americans were less likely to have impaired physical (OR = 0.54, 95% CI: 0.36 0.80) or mental health (OR = 0.36, 95% CI: 0.21, 0.61), or cardiovascular diseases (OR = 0.59, 95% CI: 0.41, 0.87). The covariates/predictors that relate to the behaviors differed between the groups. We conclude that interventions to increase physical activity and healthy eating for Asian American and white adults with prediabetes should address the different covariates/predictors for each group.

New-onset constipation at acute stage after first stroke: incidence, risk factors, and impact on the stroke outcome

BACKGROUND AND PURPOSE

The prevalence of constipation after stroke varies from 30% to 60%. The incidence of new-onset constipation during the early stage of stroke remains uncertain. The present study was designed to investigate the prevalence of new-onset constipation, its risk factors, and its impact on stroke outcome in patients with their first stroke at acute stage.

METHODS

This is a prospective cohort study of 154 patients admitted with their first stroke. New-onset constipation during the first 4 weeks of stroke was recorded, using the Rome II criteria for constipation. Demographics, characteristics of the stroke, laboratory parameters, and use of medications were evaluated as risk factors for constipation. Death, recurrent stroke, and handicap at 12 weeks were regarded as poor outcome. The impact of constipation on poor outcome was also studied.

RESULTS

The cumulative incidence of new-onset constipation was 55.2% at 4 weeks poststroke. The occurrence of constipation was associated with dependence (P<0.01) and use of bedpan for defecation (P<0.05). Among patients with moderate stroke severity (NIHSS 4 to 11) at baseline, constipation at 4 weeks was associated with a poor outcome at 12 weeks.

CONCLUSIONS

New-onset constipation is a common complication of acute stroke. Its occurrence is associated with dependence and use of bedpan for defecation. Its development may predict a poor outcome at 12 weeks in patients with moderately severe stroke.

A comparison of intermittent vaginal administration of two different doses of misoprostol suppositories with continuous dinoprostone for cervical ripening and labor induction

PURPOSE

To compare the efficacy of a vaginal insert administering continuous dinoprostone with vaginal suppositories containing two different doses of misoprostol for cervical ripening and induction of labor.

STUDY DESIGN

In this prospective, randomized, double-blinded study, 118 patients with indications for induction of labor and an unfavorable Bishop score were randomly assigned to receive either continuous dinoprostone, misoprostol 35-microg suppositories, or misoprostol 50-microg suppositories.

RESULTS

No significant differences were noted among the three groups in the change of Bishop score, induction of active labor or the time from initial treatment to delivery. Active labor occurred in roughly two-thirds of the patients in an average of about 5.7-6.7 h regardless of treatment assignment. When the two misoprostol groups were combined, a shorter interval from insertion to vaginal delivery was observed in the nulliparous women receiving misoprostol than those receiving continuous dinoprostone (21.3 vs. 27.2 h, p = 0.019). Except for the significantly lower incidence of tachysystole observed in the combined misoprostol group (3.8% vs. 15.4%, p = 0.036), there were no other significant differences between the groups in mode of delivery or in adverse maternal, fetal, or neonatal effects.

CONCLUSION

Misoprostol suppositories appeared to be as effective and safe as continuous dinoprostone in inducing cervical ripening in this sample.

[Biosynthesis of a single peptide chain containing human chorionic gonadotropin beta and C3D of complement]

In view of the strong immunity-enhancing function of HEL-C3d3 designed by Dr. Paul W. Dempsey, we made our efforts to produce a similar recombinant protein of hCG beta. With polymerase chain reaction, we introduced a Bam HI restriction site into the 3' terminal of hCG beta cDNA. The new cDNA and its terminal's correctness has been confirmed by sequencing. Then we have it covalently attached to the C3d3 cDNA at the pre-designed Bam HI/Bgl II site. Having the chimeric DNA correctly cloned into the protein nuclear polyhedrosis virus (AcNPV) expression vector pVL1393, we constructed the expression vector pVL1393-(hCG beta-C3d3). The insect cells were co-transfected with the expression vector and linearized nuclear polyhedrosis virus DNA, and recombinant viruses AcNPV-(hCG beta-C3d3) were screened out. Through anti-hCG beta immunoaffnity chromatography, the recombinant hCG beta-C3d3 chimera polypeptide was purified from culture supernatant of insect cells infected by the recombinant viruses. In RIA test, the expressed product competitively inhibits the binding of 125I-hCG beta to hCG beta-antibody. On SDS-PAGE and Western blot, the recombinant peptide hCG beta-C3d3 obviously appears to be with a molecular weight of 116KD. Therefore, we arrive at a conclusion that it has a normal immunogenic ability.
