CSI: New @ York: development of forensic evidence collection guidelines for the emergency department.

Emergency department (ED) nurses care for victims of trauma almost daily. Although preservation of evidence is crucial, the ED is chaotic when a trauma patient arrives and staff members must do everything possible to save the patient's life. However, an integral responsibility of the staff nurse is collection and preservation of forensic evidence. This article provides insight into the process undertaken by a multidisciplinary team to develop a set of evidence-based guidelines for forensic evidence collection. The team compiled evidence from more than 20 articles and consultations with law enforcement officials and forensic experts. This information was used to develop a set of guidelines for forensic evidence collection in the ED or operating room. Staff educational needs presented some challenges. Training was designed to specifically address the roles of three major groups of staff: patient representatives and emergency and trauma nurses. Educational topics included evidence recognition, handling of clothing, gross/trace evidence, documentation, packaging of evidence, and use of the "chain-of-evidence" form. Practice modifications included development of a new "chain-of-evidence" form, a forensic cart in the operating room, and use of a collapsible plastic box for collection of clothing in the ED.

How motivation influences breastfeeding duration among low-income women.

In-depth interviews were conducted with 44 low-income breastfeeding women to explore the incentives and disincentives to breastfeeding experienced within 6 months postpartum. Using an individual net benefit maximization (INBM) framework based on economic theory, we assessed women's motivations, incentives, and disincentives for breastfeeding. Based on the framework and their experience breastfeeding, women fell into 3 groups: intrinsically motivated, extrinsically motivated, and successfully experienced with both intrinsic and extrinsic motivation. Successfully experienced women were most likely to breastfeed to 6 months. Intrinsically motivated women valued breastfeeding but often required information and instruction to reach breastfeeding goals. Extrinsically motivated women were least likely to continue breastfeeding even with support and instruction. Providers can screen women to determine their experience and motivation then tailor interventions accordingly. Intrinsically motivated women may need support and instruction, extrinsically motivated women may benefit from motivational interviewing, and successfully experienced women may need only minimal breastfeeding counseling.

Educational strategies to develop evidence-based practice mentors.

Basing practice decisions on sound scientific research and best available evidence is an optimal approach for making practice changes. A five-member team of nursing leaders formed an evidence-based practice (EBP) steering committee and developed an EBP model and process. This article describes the educational approaches and the development of mentors used to provide the staff nurse with the necessary knowledge and skills to use EBP successfully.

Methodologic considerations for improving and facilitating human milk research.

Over the past several decades, interest in using human milk as a biomonitoring matrix has increased. However, it is not always an easy matter for a new mother to provide a milk sample. In this article, guidance on facilitating collection of human milk is provided. This includes addressing the mother's ease in expressing a milk sample, and engaging with many audiences to reduce the likelihood of negatively impacting the already low breastfeeding rates in the United States. In addition, this article covers concepts regarding long-term storage and integrity of human milk samples to maximize the utility of those samples, and proposed methods for improving public access to the full spectrum of human milk biomonitoring data, with context to understand the information presented. The environmental chemicals and chemical classes for which robust analytical methods exist are enumerated, and a process for prioritizing the development of analytical methods for additional environmental chemicals is described.

Promoting nutrition in breastfeeding women.

Nurses have a vital role in providing nutritional education to breastfeeding women. In this article, the authors discuss the nutritional requirements for breast-feeding women in terms of micronutrients, macronutrients, and minerals. They provide recommendations for women with vegetarian diets and low-income women enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children program who may have dietary deficiencies, and they present a directed case study to provide an example of how to perform a dietary assessment and the educational support that may be offered by nurses to breastfeeding women.

Nurse-supported breastfeeding promotion: a framework for economic evaluation.

Increasingly, economic evaluation results are considered by policymakers, although few nurse-led interventions have undergone such an evaluation. Nurse-supported breastfeeding promotion is used as an exemplar to illustrate economic evaluation. Past work is critiqued and lessons learned are described.

Evidence-based screening for low bone mineral density in HIV-infected men.

Low bone mineral density, which leads to osteoporosis and fracture risk, is an emerging clinical problem in HIV-infected patients. Our evidence-based practice project screened a convenience sample of 225 HIV-infected men for low bone mineral density using the Osteoporosis Self-Assessment Tool, and of those men, 173 were also screened by quantitative ultrasound of the calcaneus. One hundred twelve men had low bone mineral density by either or both screening methods. Seventy-one of these 112 men were tested by dual-energy x-ray absorptiometry and 73% had low bone mineral density. The positive protective value of the Osteoporosis Self-Assessment Tool was 73% and for quantitative ultrasound was 88%. These results suggest that routine low bone mineral density screening should be included as standard practice for all HIV-infected patients.

Alternate light sources in sexual assault examinations: an evidence-based practice project.

The ability of sexual assault nurse examiners to correctly identify and collect DNA evidence improves patient outcomes and prosecution rates. The purpose of this paper is to present findings from a collaborative evidence-based practice (EBP) project between forensic nurses and baccalaureate nursing students. The goal of the project was to determine best practice using an alternate light source (ALS) to identify trace DNA evidence in sexual assault forensic examinations. Using the Johns Hopkins Nursing Evidence-based Practice model, the team searched several databases to summarize the limited amount of evidence available regarding this topic. Recommendations from the EBP project include: elimination of the Wood's lamp in sexual assault examinations; use of an ALS that provides appropriate wavelengths to detect DNA; education of forensic nurses about the advantages and limitations of an ALS; and additional research related to use of an ALS. By participating in similar collaborative efforts, practicing forensic nurses have the opportunity to collaborate with local colleges and universities to make complex projects more manageable while fulfilling the International Association of Forensic Nurses vision for ethical practice.

Costs related to promoting breastfeeding among urban low-income women.

OBJECTIVE: To describe the costs of providing support to breastfeeding low-income women and compares costs to cost offsets of the intervention. DESIGN: Secondary analysis of data from a randomized controlled trial of an intervention to promote breastfeeding among low-income women with full-term infants. SETTING: A university hospital and a community hospital in Baltimore, Maryland. PARTICIPANTS: Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) eligible breastfeeding women (N = 328) were randomized to usual care or the community health nurse/peer counselor intervention. METHODS: The researchers collected and described personnel and mileage costs over the entire duration of the intervention (24 weeks). Researchers also compared (using t tests) change in resources associated with breastfeeding including the number of clinic visits, hospital nights, emergency room visits, prescriptions, and formula feedings per day up to 12 weeks. RESULTS: The cost of the personnel and travel required for the intervention was $296 per woman. The use of medical care and number of formula feedings per day were similar for the intervention and usual care groups. When differences in use of medical care and formula feeding were statistically significant, the intervention group used fewer resources. CONCLUSION: Support for breastfeeding by community health nurses and peer counselors is partially offset by reducing medical care utilization and formula feeding costs.

A randomized controlled community-based trial to improve breastfeeding rates among urban low-income mothers.

OBJECTIVE: The purpose of this study was to assess whether providing a breastfeeding support team results in higher breastfeeding rates at 6, 12, and 24 weeks postpartum among urban low-income mothers. DESIGN: A randomized controlled trial with mother-infant dyads recruited from 2 urban hospitals. PARTICIPANTS: Breastfeeding mothers of full-term infants who were eligible for Special Supplemental Nutrition Program for Women, Infants, and Children (n=328) were randomized to intervention (n=168) or usual-care group (n=160). INTERVENTION: The 24-week intervention included hospital visits by a breastfeeding support team, home visits, telephone support, and 24-hour pager access. The usual-care group received standard care. OUTCOME MEASURE: Breastfeeding status was assessed by self-report at 6, 12, and 24 weeks postpartum. RESULTS: There were no differences in the sociodemographic characteristics between the groups: 87% were African American, 80% single, and 51% primiparous. Compared with the usual-care group, more women reported breastfeeding in the intervention at 6 weeks postpartum, 66.7% vs 56.9% (odds ratio, 1.71; 95% confidence interval, 1.07-2.76). The difference in rates at 12 weeks postpartum, 49.4% vs 40.6%, and 24 weeks postpartum, 29.2% vs 28.1%, were not statistically significant. CONCLUSIONS: The intervention group was more likely to be breastfeeding at 6 weeks postpartum compared with the usual-care group, a time that coincided with the most intensive part of the intervention.

Organizational change strategies for evidence-based practice.

Evidence-based practice, a crucial competency for healthcare providers and a basic force in Magnet hospitals, results in better patient outcomes. The authors describe the strategic approach to support the maturation of The Johns Hopkins Nursing evidence-based practice model through providing leadership, setting expectations, establishing structure, building skills, and allocating human and material resources as well as incorporating the model and tools into undergraduate and graduate education at the affiliated university.

Evidence-based practice: a practical approach to implementation.

Organizations often do not have processes in place to support nurses through a systematic approach for developing and evaluating nursing interventions, protocols, critical pathways, and policies that are derived from scientific evidence. The development of a framework to guide inquiry will have a positive impact on patients. This process may foster a higher level of professional engagement by nurses that may, in the long-term, help improve nurse retention and recruitment. The authors discuss a nursing evidence-based practice model and guidelines that were developed by a team of hospital and academic nurse leaders and is practical and easy to use. This model has been successfully implemented across the department of nursing as a strategic initiative. Results of the implementation have shown that staff nurses can effectively use this model with the help of knowledgeable mentors.

The mediation effect of posttraumatic stress disorder symptoms on the relationship of intimate partner violence and IFN-gamma levels.

BACKGROUND: Women who experience intimate partner violence (IPV) report greater stress and negative health consequences than nonabused women. Although an association between psychological stress and altered immune function has been shown, IPV studies have not investigated this relationship. OBJECTIVE: This study explored the association of IPV with mental health symptoms and an immune marker to determine if posttraumatic stress disorder (PTSD) symptoms mediate the effect of IPV on pro-inflammatory (IFN-gamma) cytokine levels. METHODS: A cross-sectional, comparative design was used to compare 62 women with IPV and 39 nonabused women. RESULTS: Mean IFN-gamma values were higher in abused women and in women with current PTSD symptoms. There were no significant relationships with potential confounding variables that could provide an alternative explanation for the increase in production of proinflammatory cytokines. CONCLUSIONS: PTSD symptoms mediate the association between IPV and IFN-gamma levels and may partially explain the association of mental health symptoms with physical health sequelae in IPV.

Breastfeeding duration, costs, and benefits of a support program for low-income breastfeeding women.

BACKGROUND: Breastfeeding can ameliorate some of the complex health issues faced by low-income families. Women who breastfeed and their infants have lower health care costs compared with those who formula feed. Increasing the duration of breastfeeding is recognized as a national priority, particularly for low-income women. This community-based randomized clinical trial involving low-income mothers compared usual care with an intervention comprising hospital and home visits, and telephone support by a community health nurse/peer counselor team for 6 months after delivery. METHODS: Forty-one women were recruited after delivery of a full-term singleton infant and randomly assigned to intervention or usual care groups. RESULTS: Women receiving the community health intervention breastfed longer than the women receiving usual care. The infants in the intervention group had fewer sick visits and reported use of fewer medications than infants in the usual care group. The intervention cost ($301/mother) was partially offset by cost savings on formula and health care. CONCLUSIONS: Community health nurse and peer counselor support can increase breastfeeding duration in low-income women, and has the potential to reduce total costs including the cost of support.

Interleukin-1beta elevation during the postpartum period.

During the postpartum period, women frequently report increased fatigue, which, if severe, may interfere with maternal-child bonding, delay a new mother's return to her activities of daily living, and contribute to depression. Several studies have sought to determine psychosocial contributions to fatigue during the postpartum period, but few evaluate any physiological changes that may contribute to fatigue during this time. The following study was designed to test whether the potent, pro-inflammatory cytokine interleukin-1beta (IL-1beta), known to be a physiological mediator of fatigue in several clinical and experimental conditions, is elevated in women during the postpartum period and whether it might be related to symptoms of fatigue. Levels of fatigue and the urinary excretion of IL-1beta were measured in 26 women over 4 weeks postpartum. Correlations between fatigue and activation of the inflammatory response were investigated. Results demonstrated a significant elevation in IL-1beta during the postpartum period compared to control participants (p < .05) and a significant, although delayed, correlation between IL-1beta elevation and fatigue (p < .05). These results suggest that activation of the inflammatory response, as reflected by elevation in urinary IL-1beta, occurs in association with postpartum fatigue. Studies to explore further this association and to identify specific mechanisms of action are needed.
