Occupational Health Nursing models and theories: A critical analysis in the scope of the unitary-transformative perspective.

Occupational Health Nursing (OHN) has followed a complex path to build and strengthen its theoretical basis. Starting with Public Health core principles, theories were shaped by the dualism of person worker and working environment, where sometimes the centre of the thought was given to the latter and other times to the former. The problem was not much on such conflict but on the definition of the correct OHN focus and whether genuine nursing knowledge was being applied. We are worried that other disciplines radically influenced the theoretical path taken by OHN theorists. To approach this problem, a unitary-transformative perspective can help us describe and analyse this phenomenon and engage scholars to reflect upon the accurate epistemological focus of OHN. We aimed to deepen this reflection and uncover a new OHN theoretical focus.

Building a Pluriverse of Nursologies: A paradigm for decolonial theory and knowledge development in nursing.

The imperative to decolonise health disciplines underscores the need for a critical examination of the coloniality of nursing knowledge development. Decolonising nursing requires epistemic resistance aimed at exposing and dismantling epistemological hierarchies that marginalise indigenous knowledges. This paper introduces the 'Pluriverse of Nursologies' as paradigm to guide decolonial theorising in nursing. Through a four-part exploration, I first elucidate the coloniality embedded in mainstream nursing knowledge. Next, I offer a decolonial critique of Fawcett's nursing metaparadigm as an exemplar of pyramidal epistemology. I then discuss pluriversality as an approach to decolonising nursing knowledge. Finally, I introduce the Pluriverse of Nursologies (PoN) as a meta-theoretical paradigm for theory and knowledge development that decentres and dismantles the pyramidal epistemology of colonial/modern nursing, and relinks diverse nursologies from marginalised communities to the centre of intellectual nursing discourse, thereby revitalising the theoretical landscape of the discipline.

The social processes that emergency nurses use to achieve sustainability: A constructivist grounded theory.

AIM: To examine the experiences of emergency nurses and develop a substantive theory that describes the processes they use to support or prevent sustainability in their nursing practice. DESIGN: Constructivist grounded theory. METHODS: Between February 2018 and January 2019, observations and semi-structured interviews were conducted with 29 emergency nurses. Data underwent constant comparison, and coding was performed in three phases: open, focused, and theoretical, employing constructivist grounded theory. Additionally, some situational analysis mapping was undertaken and integrated as a method to explore the broader context affecting nursing practice. The study achieved theoretical saturation and rigour was ensured through evaluations of credibility, transferability, and confirmability. RESULTS: A substantive grounded theory was constructed to describe the basic social process of 'Achieving Personal and Professional Sustainability' with subprocesses that included 'Driving forces', 'Developing and using armouries', 'Balancing work-life', and 'Making emergency work effective'. This theory delineates two phases, 'exploration and establishment' and 'maintenance', and two key properties: 'Constructing and evolving professional identity' and 'Perceiving and reshaping the meaning of effective work and care'. The theory also highlights the dynamic interplay of individual, social, and institutional elements. CONCLUSION: 'Achieving Personal and Professional Sustainability' is important for emergency nurses to sustain themselves personally and professionally in their work. IMPACT STATEMENT: This research has substantial and global impacts. Emergency nursing can use this information as a guide to better understand strategies for both personal and professional sustainability. Policymakers may use the findings to foster a supportive work environment and enhance nurse well-being. Implementation of recommendations can lead to improved patient care outcomes. The methodological approach offers potential for future research, positively impacting emergency nursing practice and workforce sustainability worldwide. REPORTING METHOD: Reporting adheres to EQUATOR's COREQ guidelines for qualitative studies. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Extension of the theory of adherence to treatment in patients with coronary heart disease.

Background: Increased knowledge of the concept of adherence is needed for development patient-centered care, nursing interventions, and guidelines for patients with coronary heart disease (CHD). The aim of this study was to test and extend the Theory of Adherence to Treatment regarding informational support in patients with CHD. Methods: The study utilized an explanatory and descriptive survey. The study was conducted in 2013 and involved 416 patients in five hospitals in Finland. The Adherence of Patients with Chronic Disease instrument and the Social Support for People with CHD instrument were used. The model was tested using structural equation modeling (SEM). Results: SEM confirmed direct associations between motivation (ß = 0.49, p < 0.001) and results of care (ß = 0.29, p < 0.01), and indirect associations between sense of normality, fear of complications, support from nurses and next of kin, and informational support to adherence to a healthy lifestyle and medication. Informational support included information and advice on CHD risk factors, physical exercise, chest pain, medication, continuum of care, and rehabilitation. Indirect standardized path coefficients varied between 0.14 and 0.45. The model explained 45% of adherence to a healthy lifestyle and medication. Conclusion: The results of this study showed that informational support is a justified extension to the original Theory of Adherence to Treatment in Patients with CHD. Informational support seems to offer a new perspective that can be used to develop patient-centered nursing interventions and thus support adherence to treatment by patients with a lifelong disease such as CHD.

Technology-based parent school: A randomized controlled trial.

OBJECTIVE: This study was conducted as a randomized controlled trial to evaluate the technology-based parent school program. DESIGN: The study was conducted in the well-child care outpatient clinic of a hospital in Turkey. Data were collected between October 31, 2022 and February 17, 2023. The parent school was prepared based on Meleis' transition theory. SAMPLE: Forty-eight parents participated in the study. Parents in the intervention group participated in a 10-week parent school program (five website modules, five online interactive group trainings, and counseling). MEASURES: Data were collected before the program, after the program, and 1 month after the program. RESULTS: There were increases in the mean scores of the "Parent Skill Assessment Form" and "Skills Assessment Form for the Toddler Development" items in the intervention group compared to the control group. The difference between the groups in the mean scores of the Self-Efficacy for Parenting Task Index Toddler Scale (1-3 years) was not statistically significant. However, the difference between the times was statistically significant. CONCLUSION: It was concluded that the technology-based parent school training program could guide parents with children aged 1-3 years on child-rearing. TRIAL REGISTRATION: It was registered at ClinicalTrials.gov in May 2022 (NCT05370989).

Theory of health promotion for sexual and gender minority populations with cancer.

BACKGROUND: Structural factors (e.g., cisheteronormativity) promote minority stressors, which generate healthcare disparities among sexual and gender minority (SGM) populations (also known as lesbian, gay, bisexual, transgender, queer, intersexual, asexual, and other sexual and gender-expansive persons--LGBTQIA+) with cancer. The individual's biological, behavioral, social, and psychological response to minority stressors will vary throughout their life course. However, there is a lack of empirical and theoretical guidance for conceptualizing health outcomes among SGM subgroups. PURPOSE: To propose a nursing theory for the health promotion of SGM populations with cancer. METHODS: Walker and Avant's strategies for theoretical derivation were followed. RESULTS: I present the definition, theoretical assumptions, concepts, propositions, and implications for practice, education, research, and policy of the derived theory. DISCUSSION AND CONCLUSION: The theory provides a nursing framework to understand and address the multilevel impact of minority stress on the health of SGM individuals throughout their cancer care continuum.

Qualitative nursing research: evidence of scientific validation from a translational perspective.

Abstract: This article aims to reflect on scientific validation strategies in qualitative research in the light of translational theory in nursing. It is a reflection based on translational theory applied to nursing in strategies for validating qualitative studies. From this angle, validation is recognized as an adaptable construct, capable of eliciting/favoring an understanding of the subjectivity of the target audience in its relationship with the object of interest/study/research. The potential for advancing the science-profession lies in the interdisciplinary confluence of validation mechanisms, qualitative studies, the translational perspective, and nursing research. This confluence has the capacity to extend beyond theoretical and epistemological aspects. However, it is crucial to emphasize its profound, expressive, and relevant impact on the construction of scientific evidence. This impact aims to enhance the rigor and reliability of qualitative research, thereby bolstering its credibility and applicability in clinical practice.

Clinical practice guidelines of foot care practice for patients with type 2 diabetes: A scoping review using self-care model.

BACKGROUND: Type 2 diabetes can lead to severe foot complications, making self-care education, guided by clinical guidelines, crucial. However, fragmented and dispersed recommendations challenge effective implementation of these guidelines. Bringing together recommendations and presenting them according to a self-care model can provide a solid framework and facilitate the interpretation of results. AIMS: to map the international guidelines that provide recommendations to nurses to enable people with type 2 diabetes for foot self-care and synthesize the recommendations according to the key concepts of the middle-range theory of self-care for chronic diseases. DESIGN: A scoping review was undertaken, using the methodological guidance of the Joanna Briggs Institute. DATA SOURCES: Databases were searched between September 2022 and June 2023, including PubMed, CINAHL, PsycINFO, Scopus, Web of Science Core Collection, ProQuest Dissertations and Theses Global, guideline websites and related professional association websites. The databases were chosen for their comprehensive coverage of the area. METHODS: Eligible articles included guidance documents providing foot care recommendations for diabetes, published or updated between 2013 and 2023. Two reviewers summarized the recommendations presented in at least two guidelines according to the key concepts of the self-care model. The PRISMA-ScR checklist was used. RESULTS: Seventeen guidelines were included. In total, we synthesized 175 recommendations. The recommendations were framed in three dimensions and their respective categories: Self-care maintenance (education for prevention, control of risk factors, daily foot care, footwear, and socks), Self-care monitoring (foot inspection, detection of signs of infection, and detection of other diabetes-related foot disease complications), and Self-care management (responses to signs and symptoms, foot wound care, follow-up with health professionals, and health services). CONCLUSIONS: The main aspect of foot care revolves around daily care, including cleaning, moisturizing, nail care, selecting appropriate footwear, and regular inspection of both feet and footwear.

Models for designing health-oriented nursing practice : contributions to nursing practice and the nursing discipline / Des modèles pour concevoir la pratique infirmière pour la santé : quels apports à la pratique et la discipline infirmières ?

Health generally represents what nurses should strive for in their practice. However, due to their general nature, the definitions of health are problematic for designing a health-oriented nursing practice. Rather than attempting to design it through a conceptual definition of what health is, some authors from the human sciences suggest using models that allow for a concrete commitment to health. Although this avenue is little explored in nursing, it is suggested that these practice-oriented health models would make it possible to design actionable mechanisms that generate health through practices, like nursing. The objective of this article is, through existing practice-oriented health models, to propose actionable mechanisms of health-oriented nursing practice. By invoking two models, from the writings of the philosopher Nordenfelt, as well as the sociologist Venkatapuram, two illustrations are proposed, both of which allow us to propose different actionable mechanisms. Anchored in the values that support a health-oriented practice, as well as in a descriptive component, this reflection highlights the potential of such models to concretely pursue a health-oriented nursing practice. These proposals appear to be promising for the participation of nursing science in the transdisciplinary understanding of health.

La santé représente généralement ce vers quoi les infirmières devraient tendre dans leur pratique. Toutefois, par leurs natures générales et parfois divergentes, les définitions du concept de santé s'avèrent problématiques pour concevoir une pratique infirmière engagée pour la santé. Plutôt que de tenter de la concevoir par une définition du concept de santé, certains auteurs des sciences humaines suggèrent de recourir à des modèles qui permettent de s'y engager concrètement. À partir de modèles existants de pratique pour la santé, l'objectif de cet article est de proposer des mécanismes actionnables permettant de générer une pratique infirmière pour la santé. Par l'invocation de deux modèles, provenant des écrits du philosophe Nordenfelt, ainsi que du sociologue Venkatapuram, deux illustrations sont proposées, permettant toutes deux de concevoir différents mécanismes actionnables. Par un ancrage dans les valeurs constitutives d'une pratique pour la santé, et par une composante descriptive, cette réflexion met en évidence le potentiel de tels modèles pour poursuivre concrètement une pratique infirmière pour la santé. Ces propositions semblent porteuses à la participation des sciences infirmières à la compréhension transdisciplinaire du concept de santé.

[For transdisciplinarity in nursing]. / Pour la transdisciplinarité en sciences infirmières.

In the 1960s, the integration of nursing training into university led to the development of theories specific to the discipline. Although described as "nursing-specific", these theories have significant conceptual shortcomings. Since 1990, interdisciplinary approaches have been emerging to enrich nursing practice and theory. Today, it is crucial to adopt a transdisciplinary approach in order to respond effectively to current and future healthcare needs.

Applying Comfort Theory to Improve Outcomes for People in Sickle Cell Crisis.

When people with sickle cell disease in vaso-occlusive crisis need hospitalization, they often experience fragmented and disparate treatment. Racial, gender, and socioeconomic treatment bias by providers, including nurses, is complicated by the current reactionary United States (US) controlled substance policies. To provide high-quality and respectful care, nurses can use Kolcaba's Comfort Theory as the framework for a holistic plan to assess, deliver individualized interventions, and evaluate outcomes for people experiencing vaso-occlusive crisis. Once in the electronic medical record, it can guide care during future hospitalizations. By refocusing on the nursing value of providing comfort care to individuals in distress, nurses can change treatment outcomes for clients.

Heuristic Research in Nursing Science.

The purpose of this article is to reintroduce and describe the processes and phases of heuristic inquiry and to illustrate how the method can advance nursing science. Heuristic inquiry is a rigorous, systematic, phenomenologically orientated research method developed by Clark Moustakas for investigating, discovering, and understanding the nature and meaning of living experiences. Heuristic inquiry invites the inclusion of the researcher's autobiographical living of experience being investigated honoring the personal experiences of the phenomenon from self and each participant in the research study. The author proposes that heuristic inquiry be used in nursing science by including a theoretical interpretive process connecting the thematic essences of the nursing conceptual framework guiding the study. Nursing theory-guided heuristic research advances the study of caring for persons experiencing human-environmental-health transitions to enhance human betterment and wellbecoming.

Exploring Psychedelics for Alleviating Existential and Spiritual Suffering in People With Serious Illnesses: Links to the Theory of Self-Transcendence.

The fields of palliative and holistic Nursing are dedicated to providing comprehensive care for the person, emphasizing special attention to the existential and spiritual aspects of care. Psychedelic-assisted therapy has emerged as a promising approach for symptom management in individuals with serious illnesses, particularly those of existential and spiritual origin. People who undergo challenging experiences, as is the case with serious illnesses, often undergo an identity crisis and question the purpose of their lives. Psychedelic therapy, when conducted properly by trained professionals, can facilitate self-exploration and self-transcendence, opening doors to states of expanded consciousness and fostering a profound connection with oneself. This experience can help patients develop a greater sense of self-awareness and a deeper understanding of their existential and spiritual issues, enabling them to find meaning and inner peace. The Theory of Self-Transcendence theory provides a Nursing framework for understanding how psychedelic-assisted therapy can facilitate, through self-transcendence, the journey of spiritual and existential healing, offering the possibility of achieving wellbecoming from a state of vulnerability.

What Got Us Here Won't Get Us There: Critical History in Radical Black Re-imaginations of Canadian Nursing Histories.

As a "foursome" of nursing history students and scholars, upcoming, junior, and seasoned, we presented a panel on new work and possibilities related to histories of Blackness and Black nurses in Canadian nursing history. Our presentation was the 2023 keynote Hannah Panel Presentation for the joint Canadian Society for the History of Medicine (CSHM-SCHM) and the Canadian Association for the History of Nursing (CAHN-ACHN) conference. Reflecting and expanding our perspectives, we share the relevance and significance of engaging with histories of Canadian Blackness and (in)visibility of Blackness in nursing history. This paper considers the overarching question of how does engaging with histories of Canadian Blackness serve as an anti-racist strategy when examining, analyzing and understanding the history of nursing and health care? A core tenant of this work aims at acknowledging how institutional relationships of power are reproduced within scholarship unless there is space for radical re-imaginations. The disruption to power is achieved by exploring the connections between nursing and history from the perspective of Black nurses' history or Black feminist thought. We also disrupt power by our form, in challenging expectations of scientific inquiry as the only format of valid knowledge production within the discipline. Possibilities of arts-based methodology as a site for democratization in nursing knowledge are evoked through the metaphoric language (water, fire, air and earth) interwoven within the text. We highlight how each of us engages with nursing history, further complicating previous narratives of our collective Canadian past. In publishing our thoughts on historical inquiry in a nursing journal, we hope to provoke more curiosity and interest in history within our discipline as a site for liberation!

What is nursing in advanced nursing practice? Applying theories and models to advanced nursing practice-A discursive review.

AIM: This article appraises models and theories related to advanced nursing practice. It argues that while the role of the advanced nurse practitioner builds on and extends beyond traditional nursing, it remains firmly grounded in 'caring'. BACKGROUND: The stereotype that nurses 'care' and doctors 'cure' is fading. Increasingly, nurses have crossed boundaries and conducted independent assessment, diagnosis, prescribing and consultation, which used to be the doctor's role. Confusion and argument have arisen due to the higher-level practice of the advanced nurse practitioner, as many questions where these 'doctor nurses' stand. DESIGN: A literature review. DATA SOURCES: Databases, including CINAHL, Medline and Google Scholar, were searched. METHOD: Databases were searched, and relevant studies and review articles from 1970 to 2023 were identified using the following keywords: 'advanced nurse practitioner', 'nurse practitioner', 'advanced nursing', 'advance practice', 'nurse practitioner', 'nursing theory' and 'nursing model'. RESULTS: Although advanced nurse practitioners identify themselves as nurses, there is limited use of nursing theory to conceptualize this new level of practice and to define their contribution to the multi-disciplinary team. It is noted that a holistic approach to personalized patient care, based on therapeutic relationships and effective communication, may help us identify the unique contribution of the advanced nurse practitioner. CONCLUSIONS: The development of advanced nursing theory needs to capture this holistic approach and its caring element to recognize the value and strengthen the identity allegiance of this hybrid role. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Holistic approach and patient-centred care, effective communication and the therapeutic relationship are strong characteristics relating to ANP practice, the latter of which is yet to be clearly defined and captured in nursing theories. Conceptualizing ANP practice and capturing their valuable nursing care will enable better understanding and clarity for the role to realize its full potential.

A concept analysis of psychological trauma in labour and delivery nurses.

AIM: To facilitate an understanding of the risk for psychological trauma in labour and delivery nurses. DESIGN: Concept analysis. METHODS: The Walker and Avant method of concept analysis was applied to 56 articles. The characteristics, antecedents, and consequences of psychological trauma in labour and delivery nurses were identified. DATA SOURCES: Peer-reviewed articles in English from CINAHL, PubMed and Google Scholar were reviewed on July 2023. RESULTS: The characteristics of psychological trauma in labour and delivery nurses are overwhelming distress, intrusive symptoms, avoidance and numbing behaviours, hypervigilance or hyperarousal, emotional dysregulation, cognitive distortions, and interpersonal challenges. The antecedents are exposure to one or more of the following nurse-specific traumas: natural or person-made disasters, historical role limitations, second victim situations, secondary trauma, system-mediated or over-medicalized care, insufficient resources, or workplace incivility. The consequences are disruptions in mental health, diminished physical health, alterations in relationships, and variable work performance. CONCLUSION: Labour and delivery nurses experience unique causes of psychological trauma due to their practice environment and patient population. The consequences of labour and delivery nurses' psychological trauma extend beyond individual health and impact the quality of patient care and organizational capacity. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Furthermore, research is needed to inform education, support and policy measures to mitigate harm effectively. WHAT PROBLEM DID THE STUDY ADDRESS?: Nurse-specific trauma theory has not been applied to the unique labour and delivery environment with a high incidence of patient trauma. WHAT WERE THE MAIN FINDINGS?: Multiple causes of trauma in the perinatal context have created a pervasive yet largely preventable issue. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: This research will impact labour and delivery nurses, their leadership, and their patients. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Refining Mishel's Reconceptualized Uncertainty in Illness Theory: Explaining the Development of Uncertainty in Chronic Illness.

Background and Purpose: Mishel's Reconceptualized Uncertainty in Illness Theory describes the changed, more positive appraisal of uncertainty over time in a chronic disease. Therefore, Mishel referred to "probabilistic thinking" and "self-organization." The description of these concepts remained highly abstract, limiting the understanding of how change of uncertainty comes about. We aimed to elaborate on this gap and at refining the theory. Methods: We conducted a study consisting of three parts: (a) concept analyses of "probabilistic thinking" and "self-organization," (b) longitudinal qualitative study to investigate uncertainty experience over time, and (c) triangulation of (a) and (b) to develop theoretical propositions. Results: We developed five theoretical propositions in syllogistic form: (a) if persons experience uncertainty, they think probabilistically to assess the existentiality of potential consequences, (b) if they expect existential consequences, they experience uncertainty as a threat, (c) if the existentiality of uncertainty diminishes, then individuals accept uncertainty as an inherent part of illness, (d) if they accept uncertainty, they cognitively reframe it in a positive way in order to promote recovery, and (e) if persons reexperience uncertainty, they reassess the existentiality of potential consequences. Implications for Practice: We propose "health belief" as a mechanism driving "cognitive reframing" to explain the interrelation between uncertainty and a more positive experience. "Existential uncertainty" offers a new perspective on preventing a change in uncertainty experience. The new concepts can provide guidance to take measures to reduce existential uncertainty and promote health beliefs to change the experience of uncertainty from a negative to a more positive one.
