RESUMEN

Particularly expressed in the kidney, αKlotho is a transmembrane protein that acts together with bone hormone fibroblast growth factor 23 (FGF23) to regulate renal phosphate and vitamin D homeostasis. Soluble Klotho (sKL) is released from the transmembrane form and controls various cellular functions as a paracrine and endocrine factor. αKlotho deficiency accelerates aging, whereas its overexpression favors longevity. Higher αKlotho abundance confers a better prognosis in cardiovascular and renal disease owing to anti-inflammatory, antifibrotic, or antioxidant effects and tumor suppression. Serine/threonine protein kinase C (PKC) is ubiquitously expressed, affects several cellular responses, and is also implicated in heart or kidney disease as well as cancer. We explored whether PKC is a regulator of αKlotho. Experiments were performed in renal MDCK or NRK-52E cells and PKC isoform and αKlotho expression determined by qRT-PCR and Western Blotting. In both cell lines, PKC activation with phorbol ester phorbol-12-myristate-13-acetate (PMA) downregulated, while PKC inhibitor staurosporine enhanced αKlotho mRNA abundance. Further experiments with PKC inhibitor Gö6976 and RNA interference suggested that PKCγ is the major isoform for the regulation of αKlotho gene expression in the two cell lines. In conclusion, PKC is a negative regulator of αKlotho gene expression, an effect which may be relevant for the unfavorable effect of PKC on heart or kidney disease and tumorigenesis.

RESUMEN

BACKGROUND: Accurate emergency department (ED) triage in the geriatric population is an important nurse-sensitive quality indicator; however, few quality indicators are verified for impact. PURPOSE: To examine the relationship between triage accuracy in adults older than 65 years and Core Measures for acute myocardial infarction (AMI) and heart failure (HF). METHODS: A correlational approach was used to determine strength and direction of the relationship between variables. RESULTS: Strong positive correlations were found between triage accuracy and mortality for AMI and HF, as well as with 30-day hospital readmissions for AMI. A weak negative correlation was found between triage accuracy and 30-day hospital readmissions for HF. CONCLUSIONS: Accurate triage can lead to a more effective care trajectory for patients, better adherence to Core Measures, and better outcomes. Accuracy in triage for AMI and HF is a valid indicator of ED quality care.

RESUMEN

THE PURPOSE: Of this study was to understand emergency nurses' use of frailty to inform care, disposition decision-making, and further assessment. METHODS: A qualitative, descriptive, exploratory approach was used. Field notes from group discussions held during a conference presession on frailty and post-session evaluation data were analyzed. RESULTS: Two common ideas threaded these discussions: frailty as vulnerability to "falling through the cracks" and that of an iceberg. Participants stressed the broad and expansive ramifications of frailty, and lack of structure/process to accurately describe, quantify, and utilize the concept. Participants described issues of physical and emotional/social fragility, including being unable to complete activities of daily living independently; also of concern were the patients' social determinants of health and financial challenges. CONCLUSION: The conceptual understanding of frailty encompassed physical, social, cognitive, and access deficits. Emergency nurses are aware of this concept and would conduct formal frailty screening if provided with training, time, and resources.

RESUMEN

BACKGROUND: Professional ethics in nursing exist to guide care and allow for decision-making to be patient-centered. In the current medicolegal landscape post-Roe and in light of bans on gender-affirming care, the decision-making processes of emergency nurses in the clinical environment of care as informed by both professional and personal ethics are an important area of inquiry. AIM: The aim of this study was to examine the contribution of moral courage to decision-making by emergency nurses. RESEARCH DESIGN: A mixed-methods exploratory sequential approach was used, using a standard demographics form and the Nurses Moral Courage Scale to collect quantitative data. These data were used to inform an interview guide for qualitative data collection. Situational analysis was used to analyze the interview data. ETHICAL CONSIDERATIONS: Prior to recruitment, this study was reviewed and approved by the University of Massachusetts IRB (#00003909). Participants were provided with an informed consent document at the time of registration and at the time of interview; participants provided both signed consent and verbal assent. Participants were assigned study codes to maintain anonymity and data were maintained in a secure University cloud. PARTICIPANTS AND RESEARCH CONTEXT: US-based emergency nurses working in environments with care limitations. RESULTS: 70% of respondents reported that they would speak up if they were aware of a situation that was ethically challenging. Respondents reported that it was fairly easy or very easy to defend their values when addressing ancillary staff, coworkers, authorities outside the organization, patients, and patient families. Respondents reported challenges in defending their professional values to charge nurses, physicians, or administrators. In response to a serious ethical problem, 65.8% of respondents answered that they would bring up the problem for discussion, 21.1% would file an internal report, and 13.2% would report externally. Interview participants reported significant social and professional barriers to acting in response to an ethical violation. Willingness to act centered on personal values and not professional codes of ethics. CONCLUSIONS: While emergency nurses in this study reported high perceived levels of moral courage, they also reported low willingness to act directly, citing burnout and significant social and professional barriers. Adherence to professional codes of ethics is not the primary driver of moral courage.

RESUMEN

INTRODUCTION: Freestanding emergency departments (FSEDs) are emergency facilities not connected to inpatient services. The percentage of FSEDs of all EDs grew from 1% in 2001 to 12% in 2017, making FSEDs a substantial subset of US emergency care. The purpose of this study was to describe the individual attributes and environmental conditions of registered nurses working in FSEDs in the US. METHODS: A quantitative descriptive exploratory design with cross-sectional survey methodology. RESULTS: A total of 364 emergency nurses responded to the survey. Most reported their FSED was open 24 hours/day (99.5%), with board-certified emergency physicians onsite (91.5%) and a mean of 3.6 RNs working per shift. Resources immediately available in more than 50% of FSEDs included laboratory and imaging services, and in fewer than 30% of FSEDs included behavioral health care, MRI, obstetric care, orthopedic care, neurologic care, and surgical consult care. Respiratory therapy was reported by 39.6% of respondents as being immediately available. A significant minority of respondents expressed concerns about adequacy of resources and training and the effect on patient care in both survey (30% of respondents) and open-ended questions (42.5% of respondents). DISCUSSION: The practice environment of emergency nurses in FSEDs was reported as having positive elements; however, a substantial subpopulation reported serious concerns. FSEDs adhere to some of the standards put forward by the American College of Emergency Physicians, with notable exceptions in the areas of staffing RNs, staffing ancillary staff, and availability of some resources.

RESUMEN

INTRODUCTION: Over the past 15 years, the emergency nurse practitioner has been recognized as a nursing specialty role with dedicated scope and standards of practice. However, a paucity of objective data exists to validate the actual practice of emergency nurse practitioners in the emergency care setting. The purpose of this pilot study was to describe the initial acuity of patients assigned to emergency nurse practitioners, actions, decisional complexity, and disposition decisions of advanced practice nurses as they function in emergency departments in a single system. METHODS: This descriptive exploratory study used retrospective chart data to gain understanding. RESULTS: The most common Emergency Severity Index level seen by emergency nurse practitioners was Emergency Severity Index 3. Of 8513 encounters with Emergency Severity Index level data, 21% were triaged at Emergency Severity Index 2, 56% at Emergency Severity Index 3, 21% at Emergency Severity Index 4, and only 2% at Emergency Severity Index 5. Half of encounters resulted in a Current Procedural Terminology code of 99825 or higher and 94% were coded at 99824 or higher. There were a high percentage of admissions including intensive care unit admissions. DISCUSSION: Although descriptive, this study is highly illustrative of the broad scope of complex skills and clinical decision making required to perform as an advanced practice nurse in the emergency department. Further examination of education and training is warranted.

RESUMEN

INTRODUCTION: Although the ED triage function is a critical means of ensuring patient safety, core competencies for ED triage are not well defined in the literature. The purpose of the study was to identify and validate emergency triage nursing competencies and to develop a competency verification process. METHODS: A sample of 1181 emergency nurses evenly divided between roles with oversight of triage training and competency assessment (manager-level and staff nurses performing triage) completed an online survey evaluating competency elements that comprised the following in terms of frequency and importance, training modalities, and evaluation methods: expert assessment, clinical judgment, management of medical resources, communication, and timely decisions. RESULTS: Both manager-level and triage nurses agreed on the importance of the identified competencies. Gaps in training and evaluation were reported by both staff nurses and manager-level nurses. Triage nurses reported less training offered and less competency evaluation compared with manager-level nurses. Triage nurses reported performing all competencies more frequently and at higher level of competency than manager-level nurses reporting on triage nurse performance. DISCUSSION: This study provides both a standard set of triage competencies and a method by which to evaluate them. Managers and educators might consider this standard to establish initial triage role competency and periodic competency assessment per institutional guidelines. The gap in perceived education and evaluation suggests that standard education and evaluation processes be adopted across emergency departments.

RESUMEN

INTRODUCTION: The study purpose was to obtain an understanding of both the types of questions mandated for the triage encounter in emergency departments across the United States and how emergency nurses perceive the relevance of these questions to the triage process. METHODS: A qualitative descriptive exploratory study using focus group data was used. Data were collected at an in-person emergency nursing conference held in September 2022. Data were analyzed using Mayring's 8-step process. RESULTS: Participants (n = 35) voiced concerns about a lack of expertise at all points in the triage process. The overarching problem is reported as data required by regulatory agencies are conflated with triage assessment information. Participants in this study reported that the conflation of the triage assessment with regulatory compliance is causing significant issues in the ability of emergency nurses to appropriately evaluate patient presentations. Thematic categories were identified as who's assessing the patients? assessment or compliance? important questions, situationally important questions, questions asked before discharge, and the lack of emergency nurse input. DISCUSSION: The conflation of regulatory data collection with patient assessment at the initial triage encounter challenges the ability of the emergency nurse to rapidly and accurately identify patients at risk of deterioration. We recommend that initial triage processes encompass questions that focus on establishing the stability of the patient and the safety of the waiting room and include inquiry relevant to the patient presentation.

RESUMEN

INTRODUCTION: Charge nurses are shift leaders whose role includes managing nursing resources and facilitating appropriate patient care; in emergency departments, the charge nurse role requires both clinical and leadership skills to facilitate the flow of patients, while ensuring patient and staff safety. Literature on orientation and specific training is notably sparse. This study aimed to evaluate the content and process of core competency training and identify evaluation and implementation strategies necessary to improve charge nurse performance in United States emergency departments. METHODS: A modified Delphi technique was used in phase 1 and a qualitative content analysis method was used in phase 2 to address specific aims of the study. RESULTS: In total, 427 emergency nurse managers, directors, educators, and charge nurses responded to the initial survey to identify elements, teaching modalities, and evaluative processes; 22 participated in 1 of 2 focus groups to provide further information about the pedagogical approaches to teaching emergency charge nurse competencies. The top 5 competencies were identified as patient flow management, communication, situational awareness, clinical decision making, and nurse-patient assignment, with understanding that each competency overlapped significantly with the others. Low-fidelity simulation and gamification were identified as a preferred method of both training and evaluation. DISCUSSION: These findings have the potential to support a standardized approach to emergency charge nurse training and evaluation focusing on communication skills, clinical decision making, and situational awareness to facilitate safe and effective nurse-patient assignment and emergency department throughput.

RESUMEN

BACKGROUND: Basic trauma education for emergency department (ED) staff is available, but there are currently no advanced trauma nursing practice standards for ED nurses. OBJECTIVE: The purpose of this study was to identify consensus-based elements of an advanced trauma nursing program for ED nurses. METHODS: We used a modified Delphi process with three rounds of online survey data collection to ensure a large group of geographically diverse experts. Data were collected from February 2023 to May 2023. The sample for Round 1 was recruited from members of the Emergency Nurses Association reporting job titles, including trauma coordinator, trauma nursing core course instructor, and vice president of trauma services (n = 829). Participants in subsequent rounds were drawn from respondents to the initial invitation to participate (n = 131). Members of an emergency nursing research council with clinical and research expertise reviewed the results and provided expert input. RESULTS: An initial sample of 131 experts identified 17 elements that were assigned a median score equivalent to "agree/strongly agree" (i.e., median 4/5 or 5/5) in Round 2 (n = 69). These elements were presented in Round 3 (n = 43) to determine a rank order. Critical thinking/clinical judgment was the overall priority, followed by assessment/reassessment and early recognition of trauma. CONCLUSIONS: Emergency department trauma care experts identified priority content for advanced trauma education. Heterogeneity in the final ranking of components for this advanced trauma course, specifically differences by facility, regional, or demographic characteristics, suggests that training and education may not conform to a one-size-fits-all model.
