Clumped isotopes reveal relationship between mussel growth and river discharge.

Freshwater mussels preserve valuable information about hydrology, climate, and population dynamics, but developing seasonal chronologies can be problematic. Using clumped isotope thermometry, we produced high-resolution reconstructions of modern and historic (~ 1900) temperatures and δ18Owater from mussel shells collected from an impounded river, the Brazos in Texas, before and after damming. We also performed high-resolution growth band analyses to investigate relationships between mussel growth rate, rainfall, and seasonal temperature. Reconstructed δ18Owater and temperature vary little between the modern (3R5) and historic shell (H3R). However, a positive relationship between reconstructed δ18Owater and growth rate in H3R indicates that aside from diminished growth in winter, precipitation and flow rate are the strongest controls on mussel growth in both modern and pre-dam times. Overall, our results demonstrate (1) the impact, both positive and negative, of environmental factors such as flow alteration and temperature on mussel growth and (2) the potential for clumped isotopes in freshwater mussels as a paleohydrology and paleoclimate proxies in terrestrial environments.

Distinct Nausea Profiles Are Associated With Gastrointestinal Symptoms in Oncology Patients Receiving Chemotherapy.

BACKGROUND: Unrelieved chemotherapy-induced nausea (CIN) occurs 48% of patients undergoing chemotherapy and is one of the most debilitating symptoms that patients report. OBJECTIVE: The aims of this study were to identify subgroups of patients with distinct CIN profiles and determine how these subgroups differed on demographic and clinical characteristics; severity, frequency, and distress of CIN; and the co-occurrence of common gastrointestinal symptoms. METHODS: Patients (n = 1343) completed demographic questionnaire and Memorial Symptom Assessment Scale 6 times over 2 cycles of chemotherapy. Latent class analysis was used to identify subgroups of patients with distinct CIN profiles. Differences among these subgroups were evaluated using parametric and nonparametric statistics. RESULTS: Four distinct CIN profiles were identified: none (40.8%), increasing-decreasing (21.5%), decreasing (8.9%), and high (28.8%). Compared with the none class, patients in the high class were younger, had a lower annual household income, had child care responsibilities, had a lower Karnofsky Performance Status score and a higher Self-administered Comorbidity Questionnaire score, and were more likely to have received chemotherapy on a 14-day cycle and a highly emetogenic chemotherapy regimen. In addition, patients in the high class reported high occurrence rates for dry mouth, feeling bloated, diarrhea, lack of appetite, abdominal cramps, difficulty swallowing, mouth sores, weight loss, and change in the way food tastes. CONCLUSIONS: That 60% of the patients reported moderate to high CIN occurrence rates confirms that this unrelieved symptom is a significant clinical problem. IMPLICATIONS FOR PRACTICE: Nurses need to evaluate patients' level of adherence to their antiemetic regimen and make appropriate referrals for physical therapy, psychological services, and dietary counseling.

Teams Model of Clinical Nursing Education: An Innovative Approach.

The need for registered nurses has never been greater. Only through thoughtful academic-practice partnerships will it be possible to align the current and future demands of the workplace with the knowledge, attitudes, and skills that are required. Outdated nursing education models that treat practice partners as "real estate" and try to expose all students, in the same way, to the full array of patient populations, most often in acute care settings, do not serve the profession well. Attending to the heightened expectations for nurses to lead complex, interprofessional teams across an array of settings led to the development of the Teams Model of clinical nursing education. In this model, students match to practice partner facilities where they complete the majority of their clinical hours. They do not rotate through various settings, they do not spend precious practice time reorienting to new facilities, and they are not relegated to the periphery of the interprofessional team when in the student role. They become expected and valuable members of the care delivery team. They focus on developing depth as a nurse rather than breath across patient populations. The Teams Model is predicated on advancing academic-practice partnerships that provide a pipeline for workforce development and prepares the new graduate as a work-ready hire. Ongoing evaluation of the students' development and their knowledge acquisition is linked to practice partner assessments and provides support for this model as an innovative alternative to preparing the next generation of nurses. This partnership program builds confidence through immersion experiences in a consistent, welcoming, and prepared clinical environment, with opportunities to advance the priorities of the practice setting in addition to promoting positive patient outcomes. Benefits include student exposure to nontraditional fields of nursing and areas of critical shortage as well as the ability to pivot quickly as workforce needs shift.

Multiple Gastrointestinal Symptoms Are Associated With Chemotherapy-Induced Nausea in Patients With Breast Cancer.

BACKGROUND: Unrelieved chemotherapy-induced nausea (CIN) is a significant problem for patients with breast cancer (BC). OBJECTIVE: In a sample of patients with BC who were assessed before their second or third cycle of chemotherapy, study purposes were to evaluate for the occurrence, severity, frequency, and distress associated with CIN; evaluate for differences in demographic and clinical characteristics and gastrointestinal (GI) symptom occurrence rates between patients who did and did not report CIN; and determine which demographic, clinical, and symptom characteristics were associated with the occurrence of CIN. METHODS: Patients completed demographic and clinical questionnaires and the Memorial Symptom Assessment Scale for nausea and common GI symptom assessments. Univariate analyses evaluated for differences in demographic and clinical characteristics and GI symptom occurrence between patients who did and did not report CIN. Multiple logistic regression analysis evaluated for characteristics associated with CIN. RESULTS: Of the 532 patients with BC, 47.2% reported CIN occurrence. Characteristics associated with CIN group membership were poorer functional status, receipt of chemotherapy on a 14-day cycle, and higher occurrence rates of 5 GI symptoms (ie, dry mouth, vomiting, constipation, change in the way food tastes, and lack of appetite; all P < .001). CONCLUSIONS: Unrelieved CIN is a common symptom in patients with BC. This study is the first to demonstrate that 5 co-occurring GI symptoms were associated with CIN occurrence. IMPLICATIONS FOR PRACTICE: This study identified new risk factors for CIN occurrence in patients with BC. Clinicians may be able to initiate additional interventions to alleviate CIN.

SMART Oncology Nursing: Literacy, Goals, Coaching, and Empowerment.

PROBLEM STATEMENT: This study assesses the effect of a nurse-designed SMART educational intervention on goal attainment, patient empowerment, and satisfaction. DESIGN: A mixed-methods study design was used. DATA SOURCES: 68 adults with cancer were recruited from an oncology research center and randomized to the immediate or waitlist control group. Empowerment was measured using the Patient Empowerment Scale, and health literacy was measured using the Cancer Health Literacy Test. ANALYSIS: Measures were completed by the immediate group at enrollment and by the waitlist control group after an eight-week waiting period to establish an updated baseline. Participants received four learning modules on goal setting and coaching to facilitate learning and activation of knowledge. Visit data were collected by nurses based on participants' written and oral responses. FINDINGS: Goal attainment ranged from 67% to 100%. Patient empowerment scores were high at baseline and throughout. No significant differences were noted among the groups on goal attainment, empowerment, or satisfaction. IMPLICATIONS FOR NURSING: RNs can deliver a SMART educational intervention using a universal health literacy approach to support adults with cancer in creating symptom management strategies and attaining self-care goals.

Holistic Nursing in Practice: Mindfulness-Based Yoga as an Intervention to Manage Stress and Burnout.

PURPOSE: Effects of a mindfulness-based (MB) yoga practice on stress, burnout, and indicators of well-being among nurses and health care professionals (HCPs). DESIGN: A randomized controlled trial, 80 HCPs assigned to either MB yoga intervention or control group. METHOD: The MB yoga intervention group (n = 41) attended weekly yoga classes and practiced yoga independently. The control group (n = 39) did not receive the yoga intervention. Study participants completed pre- and postintervention questionnaires, instruments included (a) Perceived Stress Scale; (b) Maslach Burnout Inventory; (c) Vitality subscale of the Medical Outcomes Study Short Form-36; (d) Global Sleep Quality item, (e) Mindfulness Awareness Survey, and (f) subscale of the Brief Serenity Scale. Diurnal salivary cortisol and blood pressure were assessed pre and postintervention. RESULTS: Significant improvements (p < .01) noted in MB yoga compared with control for self-reported factors, including stress (Perceived Stress Scale), burnout (Maslach Burnout Inventory), vitality (Medical Outcomes Study Short Form-36), sleep (GSQ), serenity/inner haven (IH), and mindfulness (Mindfulness Awareness Survey). Diurnal cortisol slopes and blood pressure were not significantly improved. CONCLUSION: The MB yoga intervention had a statistically significant effect on the health and well-being of nurses and HCPs, most specifically for measures of stress; perceived stress, burnout, vitality, sleep quality, serenity, and mindfulness.

Nurses' Experiences of "Being Swamped" in the Clinical Setting and Association with Adherence to AWHONN Nurse Staffing Guidelines.

PURPOSE: Being swamped is defined as "when you are so overwhelmed with what is occurring that you are unable to focus on the most important thing." The purpose of this study was to explore the experience of being swamped in the clinical setting among nurses who are members of the Association of Women's Health, Obstetric and Neonatal Nurses (AWHONN) and the relationship of the level of being swamped to adherence to the nurse staffing guidelines. STUDY DESIGN AND METHODS: A 25-item survey was sent to ~21,000 AWHONN members by email in the Fall of 2018. It was completed by 1,198 members, representing 49 states and the District of Columbia. Questions explored timing and causes of being swamped, its effect on health care team members and patients, what helps when a nurse feels swamped, and nurses' reports of their hospital following the AWHONN nurse staffing guidelines. RESULTS: Twenty-eight percent of nurses reported being swamped daily or multiple times per day. Situations that contribute to being swamped include assignments that are too heavy, interruptions, critical patient situations, and mistakes made by others that nurses are expected to catch and fix. Teamwork and someone stepping in to help without being asked were identified as most helpful when a nurse feels swamped. Nurses practicing in hospitals following the AWHONN nurse staffing guidelines always or most of the time reported less frequency of being swamped as compared with those in hospitals that followed the guidelines some of the time, or rarely (p < 0.001). CLINICAL IMPLICATIONS: Being swamped is a common phenomenon among AWHONN members responding to the survey. The reported incidence of being swamped daily is significantly associated with the extent to which hospitals follow the AWHONN nurse staffing guidelines. Nurse leaders, hospital administrators, and staff nurses must work together to identify and initiate timely, feasible nurse staffing solutions that support the safety of patients and nurses.

Using a Delphi Method to Identify Human Factors Contributing to Nursing Errors.

PURPOSE: The purpose of this study was to identify human factors associated with nursing errors. DESIGN: Using a Delphi technique, this study used feedback from a panel of nurse experts (n = 25) on an initial qualitative survey questionnaire followed by summarizing the results with feedback and confirmation. METHODS: Synthesized factors regarding causes of errors were incorporated into a quantitative Likert-type scale, and the original expert panel participants were queried a second time to validate responses. FINDINGS: The list identified 24 items as most common causes of nursing errors, including swamping and errors made by others that nurses are expected to recognize and fix. The responses provided a consensus top 10 errors list based on means with heavy workload and fatigue at the top of the list. CONCLUSIONS: The use of the Delphi survey established consensus and developed a platform upon which future study of nursing errors can evolve as a link to future solutions. This list of human factors in nursing errors should serve to stimulate dialogue among nurses about how to prevent errors and improve outcomes. CLINICAL RELEVANCE: Human and system failures have been the subject of an abundance of research, yet nursing errors continue to occur.

Effectiveness of an Obstetrics-Based Advanced Cardiac Life Support Education Program.

OBJECTIVE: To study the effectiveness of an obstetrics-based advanced cardiac life support education (ACLS OB) program with pre- and postcourse maternal mock code drills and surveys evaluating satisfaction and self-confidence in abilities of labor and delivery (L&D) nurses to perform ACLS algorithms. DESIGN: Quasi-experimental pretest/posttest study. SETTING: Obstetric units in a community hospital system. PARTICIPANTS: Labor and delivery nurses (N = 96). METHODS: Nurses rotated through an ACLS OB course when their ACLS recertification was due. Two studies were done. Prior to the class, nurses participated in a maternal mock code drill during annual skills review, and performances were scored. One year later, nurses participated in maternal mock code drills. Results were compared with the previous year's scores. In the second study, pre- and postclass surveys were completed reflecting nurses' satisfaction and self-confidence with successfully completing elements of American Heart Association (AHA) algorithms following attendance at traditional ACLS classes versus ACLS OB. RESULTS: The scores of nurses who completed the ACLS OB course were significantly greater overall when performing ACLS MegaCode algorithms (z = -6.08, p < .001) for 18 of 21 individual elements of the algorithm. Nurses reported statistically significant increases (p < .001) in all 13 elements of satisfaction and self-confidence following completion of ACLS OB over traditional ACLS courses. CONCLUSIONS: Emphasizing changes in ACLS for obstetric patients during the precourse and using patient scenarios encountered in obstetric settings improved nurses' performance in maternal MegaCode scenarios. The course also increased self-satisfaction and self-confidence of obstetric nurses in their ability to perform ACLS algorithms.

Implementation and sustainability of the nursing and midwifery standards for mentoring in the UK.

There is growing emphasis on developing sounder processes for ensuring that nursing and midwifery students are appropriately supported and assessed in practice settings, so that they are fit to practice at the point of registration. To support this, the Nursing and Midwifery Council (NMC) in 2006, introduced new mandatory standards for practice education (NMC, 2006). The standards outline mentor responsibility for developing and ensuring the practice competence of students and provide a more defined statement regarding accountability for the decisions that lead to entry to the professional register (NMC, 2006, p. 6). Integral to the standards is the creation of a new role final placement mentors; the 'Sign-off' mentor. The concept of the 'Sign-off' mentor is new and the arrangements for implementing a sustainable approach will be challenging for placement providers. Equally challenging for universities, is the development of a framework that can support, monitor and provide evidence, that regulatory requirements have been met. This paper outlines the complexities associated with maintaining mentor competence, discusses some of the challenges for Sign-off mentors and is intended to contribute to the general discussion about specific aspects of the Nursing and Midwifery Council (NMC) standards and their sustainability in practice.

Prevention of central venous catheter-associated bloodstream infections in pediatric intensive care units: a performance improvement collaborative.

OBJECTIVE: The goal of this effort was to reduce central venous catheter (CVC)-associated bloodstream infections (BSIs) in pediatric intensive care unit (ICU) patients by means of a multicenter evidence-based intervention. METHODS: An observational study was conducted in 26 freestanding children's hospitals with pediatric or cardiac ICUs that joined a Child Health Corporation of America collaborative. CVC-associated BSI protocols were implemented using a collaborative process that included catheter insertion and maintenance bundles, daily review of CVC necessity, and daily goals. The primary goal was either a 50% reduction in the CVC-associated BSI rate or a rate of 1.5 CVC-associated BSIs per 1,000 CVC-days in each ICU at the end of a 9-month improvement period. A 12-month sustain period followed the initial improvement period, with the primary goal of maintaining the improvements achieved. RESULTS: The collaborative median CVC-associated BSI rate decreased from 6.3 CVC-associated BSIs per 1,000 CVC-days at the start of the collaborative to 4.3 CVC-associated BSIs per 1,000 CVC-days at the end of the collaborative. Sixty-five percent of all participants documented a decrease in their CVC-associated BSI rate. Sixty-nine CVC-associated BSIs were prevented across all teams, with an estimated cost avoidance of $2.9 million. Hospitals were able to sustain their improvements during a 12-month sustain period and prevent another 198 infections. CONCLUSIONS: We conclude that our collaborative quality improvement project demonstrated that significant reduction in CVC-associated BSI rates and related costs can be realized by means of evidence-based prevention interventions, enhanced communication among caregivers, standardization of CVC insertion and maintenance processes, enhanced measurement, and empowerment of team members to enforce adherence to best practices.

A collaborative approach to building the capacity for research and evidence-based practice in community hospitals.

The use of best evidence to support nursing practice and the generation of new knowledge to use in practice are hallmarks of excellence. Nurses at the bedside, however, often lack the resources and knowledge necessary to change the traditional nursing culture to one in which the use of evidence is incorporated into daily care. This article describes the experience in two hospitals using a program designed to give nurses the skills needed to engage in evidence-based care.

Over-the-counter cough and cold medication use in young children.

During a 2-year period from 2004 and 2005, emergency departments treated over 1,500 children under the age of 2 years for adverse events related to over-the-counter (OTC) cough and cold medication use; these incidents include 3 infant deaths. The risk of overdose, incorrect dosing and adverse events is increased in young children due to the greater number of colds they acquire each year. Lack of evidence to support the use of OTC medications in young children is well documented in the literature; however, people continue to use OTC medications with young children. The common cold is generally a mild, self-limited illness that usually improves with time. Recommended care and treatment for the common cold includes symptomatic treatment. This article presents and reviews the available evidence regarding the use of OTC cough and cold medications for pediatric healthcare providers. This review of the evidence will be helpful for healthcare providers to minimize risks to young children who intentionally or unintentionally ingest these medications and to educate child caregivers regarding proper use of OTC cough and cold medications with children.
