RESUMO

OBJECTIVE: The aim of this study was to explore the experience and perceived value of travel nurses in a children's hospital. BACKGROUND: Children's hospitals face unique challenges related to highly specialized care requirements and workforce expansion limitations. Travel nurses can augment nurse staffing capacity during times of intense demand and may offer insights as organizations seek to strengthen work environments. METHODS: Pediatric travel nurses currently contracted at the hospital were invited to participate in a focus group or interview. Content analysis was used to summarize information and identify themes. RESULTS: From the 56 participants, 5 themes emerged. The themes were financial, flexibility, searching for healthy work environments, nursing care, and solutions. CONCLUSIONS: Hearing the voices of travel nurses may offer valuable feedback to strengthen future professional practice environments.

RESUMO

BACKGROUND: Over the last two decades, medical schools and academic health centers have acknowledged the persistence of health disparities in their patients and the lack of diversity in their faculty, leaders and extended workforce. We established an Office of Health Equity and Inclusion (OHEI) at our pediatric academic medical center after a thorough evaluation of prior diversity initiatives and review of faculty development data. OBJECTIVE: To describe the lessons learned at a pediatric academic medical center in prioritizing and implementing health equity, diversity and inclusion (EDI) initiatives in creating the OHEI. MATERIALS AND METHODS: We reviewed internal administrative data and faculty development data, including data related to faculty who are underrepresented in medicine, to understand the role of our EDI initiatives in the strategic priorities addressed and lessons learned in the creation of the OHEI. RESULTS: The intentional steps taken in our medical center's strategic approach in the creation of this office led to four important lessons to improve pediatric health equity: (1) board, senior executive and institutional prioritization of EDI initiatives; (2) multi-specialty and interprofessional collaboration; (3) academic approach to EDI programmatic development; and (4) intentionality with accountability in all EDI initiatives. CONCLUSION: The key lessons learned during the creation of an Office of Health Equity and Inclusion can provide guidance to other academic health centers committed to implementing institutional priorities that focus their EDI initiatives on the improvement of pediatric health equity.

RESUMO

PURPOSE: The measurement of standard visual acuity (VA) is the most well-known part of any ophthalmic examination to indicate visual function. Despite this, it is insensitive in detecting early disease changes. Therefore, other visual function tests have been developed including low luminance VA (LLVA) and low luminance deficit (LLD). This scoping literature review aims to summarise the current published applications of LLVA and LLD assessments to evaluate their utility as clinical markers and research outcome measures in a variety of ophthalmic conditions. RECENT FINDINGS: Sixty-five peer-reviewed publications were included. LLVA was pioneered for use in geographic atrophy, a subtype of age-related macular degeneration, which remains the mainstay of its clinical application. However, other studies have reported additional useful applications in inherited retinal diseases including rare maculopathies and rod-cone dystrophies. Although there are some variations in testing methodology, use of the standard Early Treatment Diabetic Retinopathy Study (ETDRS) chart with a 2.0 log unit neutral density filter is the most popular approach. The optimal testing luminance is still to be defined. SUMMARY: Overall, LLVA is an earlier clinical marker of change in central retinal function than standard VA. It has been shown to be a risk factor for disease progression and a better indicator of a patient's level of everyday visual function. It is inexpensive and simple to implement using readily available standard ophthalmic equipment.

RESUMO

Nurse leaders have a responsibility to nurture a work environment that prioritizes meaningful recognition. This quality improvement project explored the perceptions of meaningful recognition of inpatient pediatric surgical nurses. Meaningful recognition provides a chance to honor all voices, particularly those that have not been previously heard. To be heard is to be honored and to be recognized is to be valued.

RESUMO

OBJECTIVE: To provide an organization-wide, systematic approach to creating and sustaining healthy work environments (HWEs) through frontline interprofessional staff education and coaching engagement. BACKGROUND: HWE has been an overarching concept in the organization's nursing professional practice model since 2014; however, few practice settings routinely translated survey findings to improve the work environment's health via local interprofessional direct care team members. METHODS: The program used a participatory approach where HWE champions committed to participate in centralized professional development activities and local quality improvement initiatives to bolster the health of area work environments. RESULTS: Fifty-one champions representing 44 practice settings participated in the professional development program. Mean HWE scores for all standards increased from year 1 to 2, with 15 practice settings seeing categorical improvement. Meaningful recognition and true collaboration were the standards most often targeted for improvement. CONCLUSION: The HWE champion role appears to be a promising strategy for engaging frontline interprofessional staff in the assessment and implementation of initiatives to improve the health of work environments.

RESUMO

The Greater Boston Nursing Collective, a consortium composed of university nursing deans and chief nursing officers within academic medical centers and specialty hospitals in Boston, Massachusetts, was formed in 2014. Since the group's inception, our mission has been to create and reinforce whole-person/whole-system healing environments to improve the health of all communities. Through our collaboration in navigating the dual epidemics of COVID-19 and structural racism within our respective organizations, and across the United States and the world, we share experiences and lessons learned. Our common mission is clearer than ever: to create safe and joyful work environments, to protect the dignity of those we are privileged to serve, and to generate policies to advance health equity to rectify societal forces that have shaped this dual epidemic. We are humbled by the many who persist despite limited rest and respite, and whose stories, innovations, and leadership we are honored to witness and share. They have defined our generation, just as nurses in earlier crises have done: leading through service to others as our purpose and privilege.

RESUMO

The lack of stringent regulations regarding raw materials for herbal supplements used for medicinal purposes has been a constant challenge in the industry. Ginkgo biloba L. leaf extracts attract consumers because of the supposed positive effect on mental performance and memory. Supplements are produced using dried leaf materials and standardized leaf extracts such as EGb 761. Adulteration of Ginkgo biloba L. plants and extracts are becoming more and more common practice due to economically driven motivation from increasing demand in the market and the high cost of raw materials and production. Reinforcement in quality control (QC) to avoid adulterations is necessary to ensure the efficacy of the supplements. In this study, liquid chromatography-high-resolution mass spectrometry (LC-HRMS) was used with principal component analysis (PCA) as an unsupervised exploratory method to analyze, identify, and evaluate the adulterated Ginkgo biloba L. plant materials and dried leaf extracts using the PCA scores and loadings obtained and compound identification.

RESUMO

BACKGROUND: Many patient safety organizations recommend the use of the action hierarchy (AH) to identify strong corrective actions following an investigative analysis of patient harm events. Strong corrective actions, such as forcing functions and equipment standardization, improve patient safety by either preventing the occurrence of active failures (i.e. errors or violations) or reducing their consequences if they do occur. PROBLEM: We propose that the emphasis on implementing strong fixes that incrementally improve safety one event at a time is necessary, yet insufficient, for improving safety. This singular focus has detracted from the pursuit of major changes that transform systems safety by targeting the latent conditions which consistently underlie active failures. To date, however, there are no standardized models or methods that enable patient safety professionals to assess, develop and implement systems changes to improve patient safety. APPROACH: We propose a multifaceted definition of 'systems change'. Based on this definition, various types and levels of systems change are described. A rubric for determining the extent to which a specific corrective action reflects a 'systems change' is provided. This rubric incorporates four fundamental dimensions of systems change: scope, breadth, depth and degree. Scores along these dimensions can then be used to classify corrective actions within our proposed systems change hierarchy (SCH). CONCLUSION: Additional research is needed to validate the proposed rubric and SCH. However, when used in conjunction with the AH, the SCH perspective will serve to foster a more holistic and transformative approach to patient safety.

RESUMO

The Dietary Supplement Label Database (DSLD) is sponsored by the Office of Dietary Supplements (ODS) and the National Library of Medicine (NLM). It provides a searchable, free database of the contents of ∼65,000 supplement labels. A companion database of analytically verified product labels [the Dietary Supplement Ingredient Database (DSID)] was created by ODS, NLM, and the USDA. There are considerable challenges to populating both databases, but the DSID faces unique analytic chemistry challenges. This article describes the challenges to creating analytically verified marketplace surveys of dietary supplement (DS) product content claims for inclusion in public databases. Nutritionists and public health scientists require information on actual exposures to DS constituents because labeled content may not match labeled product content. Analytic verification of composition of DSs provides a link to actual exposure. A public database of analytically derived DS content was developed to provide more accurate estimates of dietary intake in population-based epidemiologic studies. The DSID has conducted surveys of several types of vitamin- and mineral-containing DSs. Results showing label content claims as analytically derived values are available in the current DSID. A recent pilot project explored the feasibility of adding botanical DS products to the DSID. Candidates for future botanical DSID studies will be based on sales volume, potential public health impacts, and the availability of validated analytic methods and reference materials. Databases like DSID and the DSLD are essential for researchers and clinicians to evaluate dietary ingredient intakes in population-based epidemiologic studies. Together, these databases provide a picture of the DS marketplace. The DSID provides an analytic survey of marketed DSs. However, selection of future botanical supplements for DSID evaluation involves analytic challenges. Even when appropriate resources are available, method selection and data evaluation are resource- and time-consuming.

RESUMO

A Standard Reference Material (SRM) of seaweed, SRM 3232 Kelp Powder (Thallus laminariae) has been developed to support food and dietary supplement measurements in compliance with the Food Safety Modernization Act (FSMA) and the Dietary Supplement Health and Education Act of 1994 (DSHEA). The material was characterized for nutritional minerals, arsenic species, isomers of vitamin K1, proximates, and toxic elements. Kelp is a rich source of vitamins and minerals, and it is an excellent source of dietary iodine. Kelp also contains a large amount of arsenic, which is toxic as inorganic species but much less so as organic species. To capture the dietary profile of kelp, certified values were issued for As, Ca, Cd, Cr, Cu, Fe, Hg, I, K, Mg, Mn, Mo, Na, Pb, and Zn. Reference values for proximates were assigned. For the first time, a certified value for iodine, reference values for isomers of vitamin K1, and reference values for arsenic species including arsenosugars were assigned in a seaweed. SRM 3232 fills a gap in Certified Reference Materials (CRMs) needed for quality assurance and method validation in the compositional measurements of kelp and similar seaweeds used as food and as dietary supplements. Graphical Absract Arsenic species and isomers of vitamin K1 were determined in the development of SRM 3232 Kelp Powder (Thallus laminariae).

RESUMO

A new tobacco filler Standard Reference Material (SRM) has been issued by the National Institute of Standards and Technology (NIST) in September 2016 with certified and reference mass fraction values for nicotine, N-nitrosonornicotine, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone, and volatiles. The constituents have been determined by multiple analytical methods with measurements at NIST and at the Centers for Disease Control and Prevention, and with confirmatory measurements by commercial laboratories. This effort highlights the development of the first SRM for reduced nicotine and reduced tobacco-specific nitrosamines with certified values for composition.

RESUMO

The American Academy of Nursing has identified examples of care redesign developed by nurses who address the health needs of diverse populations. These models show important clinical and financial outcomes as summarized in the Select Edge Runner Models of Care table included in this article. A study team appointed by the Academy explored the commonalities across these models. Four commonalities emerged: health holistically defined; individual-, family-, and community-centric approaches to care; relationship-based care that enables partnerships and builds patient engagement and activation; and a shift from episodic individual care to continuous group and public health approaches. The policy implications include examining measures of an expanded definition of health, paying for visionary care, and transparency and rewards for community-level engagement.

RESUMO

The National Institute of Standards and Technology (NIST), in collaboration with the National Institutes of Health (NIH), has developed a Standard Reference Material (SRM) to support technology development in metabolomics research. SRM 1950 Metabolites in Human Plasma is intended to have metabolite concentrations that are representative of those found in adult human plasma. The plasma used in the preparation of SRM 1950 was collected from both male and female donors, and donor ethnicity targets were selected based upon the ethnic makeup of the U.S. population. Metabolomics research is diverse in terms of both instrumentation and scientific goals. This SRM was designed to apply broadly to the field, not toward specific applications. Therefore, concentrations of approximately 100 analytes, including amino acids, fatty acids, trace elements, vitamins, hormones, selenoproteins, clinical markers, and perfluorinated compounds (PFCs), were determined. Value assignment measurements were performed by NIST and the Centers for Disease Control and Prevention (CDC). SRM 1950 is the first reference material developed specifically for metabolomics research.

RESUMO

The National Institute of Standards and Technology (NIST) has established a Dietary Supplement Laboratory Quality Assurance Program (DSQAP) in collaboration with the National Institutes of Health Office of Dietary Supplements (NIH-ODS). The DSQAP invites laboratories twice annually to participate in interlaboratory studies where participants elect to measure concentrations of nutritional and/or toxic elements as well as active and/or marker compounds. One of these studies was designed to determine the effects of material granularity and sample processing techniques on measurement variability (precision) as well as to provide participating laboratories information on their performance relative to the NIST assigned values (bias) and to the other participants (concordance). Participants were asked to determine the mass fractions of Ca, Fe, and Zn, in mg/kg, in six breakfast cereal samples. Cereal samples consisted of three ground materials (homogenized wheat, wheat, and rice), two flake materials (wheat and rice) and a partially crushed material (a wheat/rice mixture). In general, approximately 25% of the laboratories processed and analyzed the suite of six cereal materials with adequate to exemplary measurement precision. Over half of the laboratories (60%) experienced measurement issues related to only a particular type of cereal matrix or for only a single element. A small number (15%) of laboratories experienced significant sample processing or measurement problems. Future studies planned by the DSQAP may be designed to use commercial products to aid laboratories with their sampling and analytical techniques.

RESUMO

Standard Reference Material 3280 Multivitamin/ Multielement Tablets was issued by the National Institute of Standards and Technology in 2009, and has certified and reference mass fraction values for 13 vitamins, 26 elements, and two carotenoids. Elements were measured using two or more analytical methods at NIST with additional data contributed by collaborating laboratories. This reference material is expected to serve a dual purpose: to provide quality assurance in support of a database of dietary supplement products and to provide a means for analysts, dietary supplement manufacturers, and researchers to assess the appropriateness and validity of their analytical methods and the accuracy of their results.

RESUMO

BACKGROUND: The 2021 Future of Nursing Report 2020-2030: Charting a Path to Achieve Health Equity recognizes increasing racial and ethnic diversity in nursing as an imperative to achieving health equity. PRACTICE INITIATIVES: Over a 3-year period, nursing and human resource leaders at Boston Children's Hospital, a tertiary care, 454-bed pediatric academic medical center in Massachusetts, developed, implemented, and evaluated specific strategies to increase racial and ethnic diversity in recruitment and hiring of the nursing workforce. These specific strategies focused on cultivating partnerships, building relationships with candidates, and supporting transition into practice. RESULTS: Significant increases in racial and ethnic diversity recruitment and hiring were achieved over the 3-year period. In 2019, strategies yielded a 6% overall increase in total registered nurse diversity hiring with an 18% increase in new graduate diversity hires over 2018. In total, 16.2% of registered nurse hires for 2019 were racially and ethnically diverse. Subsequent years yielded similar success in the recruitment of diverse registered nurses. CLINICAL IMPLICATIONS: With the projected growth of racial and ethnic minority populations, nursing and health care leaders must prioritize intentional strategic diversity recruitment and retention actions to address this imperative to advance health equity through the creation of a racially and ethnically diverse nursing workforce.

RESUMO

ABSTRACT: This article reviews several key aspects of the Theory of Active and Latent Failures, typically referred to as the Swiss cheese model of human error and accident causation. Although the Swiss cheese model has become well known in most safety circles, there are several aspects of its underlying theory that are often misunderstood. Some authors have dismissed the Swiss cheese model as an oversimplification of how accidents occur, whereas others have attempted to modify the model to make it better equipped to deal with the complexity of human error in health care. This narrative review aims to provide readers with a better understanding and greater appreciation of the Theory of Active and Latent Failures upon which the Swiss cheese model is based. The goal is to help patient safety professionals fully leverage the model and its associated tools when performing a root cause analysis as well as other patient safety activities.

RESUMO

BACKGROUND: In collaboration with the Office of Dietary Supplements at the National Institutes of Health, the National Institute of Standards and Technology issued a suite of botanical matrix reference materials (RMs) and Standard Reference Material® (SRM) for determination of isoflavones and toxic elements in kudzu dietary supplement ingredients. OBJECTIVE: RM 8650 Pueraria montana var. lobata (Kudzu) Rhizome, SRM 3268 Pueraria montana var. lobata (Kudzu) Extract, and RM 8652 Kudzu-Containing Solid Oral Dosage Form were issued with values assigned for isoflavones (puerarin, daidzin, and daidzein), toxic elements (arsenic, cadmium, and lead), and selenium. METHODS: Isoflavone values were assigned using liquid chromatography with UV absorbance or mass spectrometry detection. Element values were assigned using inductively coupled plasma mass spectrometry and results from an interlaboratory comparison exercise. RESULTS: Mass fractions for puerarin were 32.2 ± 3.2 mg/g, 128 ± 13 mg/g, and 68.2 ± 6.9 mg/g in RM 8650, SRM 3268, and RM 8652, respectively. Arsenic increases from 156 ± 14 ng/g to 849 ± 83 ng/g and cadmium decreases from 348 ± 14 ng/g to 82.1 ± 4.9 ng/g from rhizome to extract. CONCLUSION: The kudzu RM/SRM suite complements previously issued soy-related SRMs with values assigned for isoflavones, which have been studied for their potential health benefits, and expands the analytical resource by providing values for puerarin, an isoflavone not found in soy. HIGHLIGHTS: The three new kudzurmaterials are for use in the determination of isoflavones, toxic elements, and selenium. For the isoflavones, these new kudzu materials provide higher levels of daidzin and daidzein than existing soy-related SRMs, and they provide a value for an isoflavone not in existing SRMs (puerarin). Toxic elements in RM 8650 and SRM 3268 provide new botanical matrixes for use by dietary supplement manufacturers for the verification of the safety of their raw materials.
