Low-value health care, de-implementation, and implications for nursing research: A discussion paper.

Globally, the nursing profession constitutes the largest proportion of the health workforce; however, it is challenged by widespread workforce shortages relative to need. Strategies to promote recruitment of the nursing workforce are well-established, with a lesser focus on strategies to alleviate the burden on the existing workforce. This burden may be exacerbated by the impact of low-value health care, characterised as health care that provides little or no benefit for patients, or has the potential to cause harm. Low-value health care is a global problem, a major contributor to the waste of healthcare resources, and a key focus of health system reform. Evidence of variation in low-value health care has been identified across countries and system levels. Research on low-value health care has largely focused on the medical profession, with a paucity of research examining either low-value health care or the de-implementation of low-value health care from a nursing perspective. The objective of this paper is to provide a scholarly discussion of the literature around low-value health care and de-implementation, with the purpose of identifying implications for nursing research. With increasing pressures on the global nursing workforce, research identifying low-value health care and developing approaches to de-implement this care, is crucial.

Using machine learning models to predict falls in hospitalised adults.

BACKGROUND: Identifying patients at high risk of falling is crucial in implementing effective fall prevention programs. While the integration of information systems is becoming more widespread in the healthcare industry, it poses a significant challenge in analysing vast amounts of data to identify factors that could enhance patient safety. OBJECTIVE: To determine fall-associated factors and develop high-performance prediction tools for at-risk patients in acute and sub-acute care services in Australia. METHODS: A retrospective study of 672,400 patients admitted to acute and sub-acute care services within a large metropolitan tertiary health service in Victoria, Australia, between January 1, 2019, and December 31, 2021. Data were obtained from four sources: the Department of Health Victorian Admitted Episodes Dataset, RiskManTM, electronic health records, and the health workforce dataset. Machine learning techniques, including Random Forest and Deep Neural Network models, were used to analyse the data, predict patient falls, and identify the most important risk factors for falls in this population. Model performance was evaluated using accuracy, F1-score, precision, recall, specificity, Matthew's correlation coefficient, and the area under the receiver operating characteristic curve (AUC). RESULTS: The deep neural network and random forest models were highly accurate in predicting hospital patient falls. The deep neural network model achieved an accuracy of 0.988 and a specificity of 0.999, while the RF achieved an accuracy of 0.989 and a specificity of 1.000. The top 20 variables impacting falls were compared across both models, and 12 common factors were identified. These factors can be broadly classified into three categories: patient-related factors, staffing-related factors, and admission-related factors. Although not all factors are modifiable, they must be considered when planning fall prevention interventions. CONCLUSION: The study demonstrated machine learning's potential to predict falls and identify key risk factors. Further validation across diverse populations and settings is essential for broader applicability.

Nurses' knowledge and implementation of antimicrobial stewardship and infection prevention strategies in acute paediatric settings.

BACKGROUND: Nurses are the first point of contact for patients and are responsible for monitoring and reporting signs of infection. The COVID-19 pandemic cemented nurses' leadership role in infection prevention. Despite this, nurses' contribution to antimicrobial stewardship initiatives remains under-recognized. AIM: To determine how paediatric nurses understood their role and contribution to antimicrobial stewardship and infection prevention and control practices in three different acute paediatric wards. METHODS: Forty-three nurses were recruited from an adolescent ward, an oncology ward, and a surgical ward in a metropolitan tertiary children's hospital for a qualitative exploratory descriptive study. FINDINGS: Thematic and content analysis derived three themes from the data: understanding of preventable infections; embracing evidence-based guidelines to protect the patient; and roles in preventing and controlling infections and antimicrobial stewardship. Associated subthemes were: desensitized to COVID-19; understanding infection prevention and control precautions; correct use of hospital policy and guidelines; restrictions associated with the use of electronic medical records; understanding of sepsis management and the importance of timely microbiological testing; ambivalence on antimicrobial stewardship roles; and high priority placed on consumer education. CONCLUSION: Nurses' understanding of their role focused on practices such as performing hand hygiene, standard precautions, and reporting the use of high-risk antimicrobials. A lack of understanding of paediatric COVID-19 transmission and presentations was also reported. Education on best practice in infection prevention and AMS was recognized as crucial for both nurses and parents.

Family experiences and perceptions of intensive care unit care and communication during the COVID-19 pandemic.

INTRODUCTION: In 2020, during the first wave of the COVID-19 pandemic in Melbourne, visitor access to acute hospitals including intensive care units (ICUs) was initially barred, followed by a limit of one person per patient for one hour per day. This study explores the care and communication experienced by family members of ICU patients during this time. METHODS: This qualitative descriptive study was conducted at an Australian quaternary hospital. Semistructured phone interviews were conducted using an aide-memoire designed to understand participants' experiences as family of a patient during this time. Interviews were recorded, transcribed, and thematically analysed. FINDINGS: Twenty family members of patients in the ICU participated. Three major themes were identified: 'impact of restricting visiting procedures', 'family experiences of communication', and 'care and support'. Inflexible visiting restrictions had a momentous impact on families. Participants objected to having to nominate only two people to visit during the admission and the short visiting time limit. Some family members suffered extreme stress and anxiety during their absence from the bedside. Additional challenges were experienced by rural families, visitors with disabilities, and the young children of patients who were excluded. Communication with clinicians varied. Telehealth was valued by some but not universally embraced. The relationship between staff members and families and involvement in decision-making were unaffected. CONCLUSION: Families experienced significant psychological distress from being separated from their critically ill relatives. Patient care and involvement in decision-making appeared to be unchanged, but communication with staff felt to be lacking. Better alternatives to face-to-face communication must be sought to limit the impact of family separation on mental health. Families are a key link between the patient and clinicians and often play a major role in patient support and recovery after discharge. There is an urgent need to support them and facilitate meaningful engagement despite the obstacles.

Influences on nurses' engagement in antimicrobial stewardship behaviours: a multi-country survey using the Theoretical Domains Framework.

BACKGROUND: Antimicrobial resistance (AMR) is affected significantly by inappropriate antibiotic use, and is one of the greatest threats to human health. Antimicrobial stewardship (AMS) is a programme of actions promoting responsible use of antimicrobials, and is essential for limiting AMR. Nurses have an important role to play in this context. AIM: To investigate the determinants of nurse AMS behaviours and the impact of past training. METHODS: A cross-sectional multi-country survey design with mixed methods was employed. Participants were 262 nurses {223 female; mean age 44.45 [standard deviation (SD) 10.77] years} of 10 nationalities, with individual survey links sent via professional networks in five countries, alongside Twitter. Nine AMS behaviours and 14 behavioural determinants were assessed quantitatively using the Theoretical Domains Framework (TDF), and mapped to the Capability, Opportunity, Motivation - Behaviour (COM-B) model. Analysis identified differences between nurses with and without AMS training. The influence of coronavirus disease 2019 (COVID-19) on AMS behaviour was investigated qualitatively using free-text data. FINDINGS: Nurses performed all nine AMS behaviours, which were significantly higher [t (238) -4.14, P<0.001] among those who had received AMS training [mean 53.15 (SD 7.40)] compared with those who had not received AMS training [mean 48.30 (SD 10.75)]. Nurses who had received AMS training scored significantly higher in all of the TDF domains. The TDF was able to explain 27% of the variance in behaviour, with 'Skills' and 'Behavioural regulation' (e.g. ability to self-monitor and plan) shown to be the most predictive of AMS actions. Both of these domains are situated in the 'Capability' construct of the COM-B model, which can be enhanced with the intervention strategies of education and training. An increase in AMS behaviours was reported since the COVID-19 pandemic, regardless of previous training. Six core themes were linked to AMS: (1) infection prevention and control; (2) antimicrobials and antimicrobial resistance; (3) diagnosis of infection and use of antibiotics; (4) antimicrobial prescribing practice; (5) person-centred care; and (6) interprofessional collaborative practice. CONCLUSION: Nurse training has a significant beneficial effect on AMS behaviour and its determinants. Nurses who had received AMS training scored higher in all TDF determinants of behaviour compared with those who had not received AMS training, resulting in higher capability, opportunity and motivation to perform AMS behaviour. AMS education and training should be offered to nurses to enhance these factors. Future research should consider the optimal level of training to optimize AMS behaviour, with a focus on developing skills and behavioural regulation.

Interventions to improve osteoporosis medication adherence and persistence: a systematic review and literature appraisal by the ISPOR Medication Adherence & Persistence Special Interest Group.

This study aims to systematically review, critically appraise and identify from the published literature, the most effective interventions to improve medication adherence in osteoporosis. A literature search using Medline, EMBASE, Cochrane library, and Cumulative Index to Nursing and Allied Health Literature was undertaken to identify prospective studies published between January 1, 1999 and June 30, 2012. We included studies on adult users of osteoporosis medications that tested a patient adherence intervention (e.g., patient education, intensified patient care, different dosing regimens) and reported quantitative results of adherence. The Delphi list was modified to assess the quality of studies. Of 113 articles identified, 20 studies fulfilled the inclusion criteria. The most frequent intervention was education (n = 11) followed by monitoring/supervision (n = 4), drug regimens (n = 2), drug regimens and patient support (n = 1), pharmacist intervention (n = 1), and electronic prescription (n = 1). Although patient education improved medication adherence in four studies, two large-scale randomized studies reported no benefits. Simplification of dosing regimens (with and without patient support program) was found to have a significant clinical impact on medication adherence and persistence. Monitoring/supervision showed no impact on medication persistence while electronic prescription and pharmacist intervention increased medication adherence or persistence. In conclusion, this review found that simplification of dosing regimens, decision aids, electronic prescription, or patient education may help to improve adherence or persistence to osteoporosis medications. We identified wide variation of quality of studies in the osteoporosis area. The efficacy of patient education was variable across studies, while monitoring/supervision does not seem an effective way to enhance medication adherence or persistence.

Homelessness: patterns of emergency department use and risk factors for re-presentation.

OBJECTIVES: To describe patterns of service use and to predict risk factors for re-presentation to a metropolitan emergency department (ED) among people who are homeless. METHODS: A retrospective cohort analysis was undertaken over a 24-month period from a principal referral hospital in Melbourne, Australia. All ED visits relating to people classified as homeless were included. A predictive model for risk of re-presentation was developed using logistic regression with random effects. Rates of re-presentation, defined as the total number of visits to the same ED within 28 days of discharge, were measured. RESULTS: The study period was 1 January 2003 to 31 December 2004. The re-presentation rate for homeless people was 47.8% (3199/6689) of ED visits and 45.5% (725/1595) of the patients. The final predictive model included risk factors, which incorporated both hospital and community service use. Those characteristics that resulted in significantly increased odds of re-presentation were leaving hospital at own risk (OR 1.31; 95% CI 1.10 to 1.56), treatment in another hospital (OR 1.45, 95% CI 1.23 to 1.72) and being in receipt of community-based case management (OR 1.31, 95% CI 1.11 to 1.54) or pension (OR 1.34, 95% CI 1.12 to 1.62). CONCLUSIONS: The predictive model identified nine risk factors of re-presentation to the ED for people who are homeless. Early identification of these factors among homeless people may alert clinicians to the complexity of issues influencing an individual ED visit. This information can be used at admission and discharge by ensuring that homeless people have access to services commensurate with their health needs. Improved linkage between community and hospital services must be underscored by the capacity to provide safe and secure housing.

Polymerically modified layered silicates: an effective route to nanocomposites.

Polymer/clay nanocomposites have been under an extensive investigation for about 15 years. Traditional methods to modify the clay are usually limited to small organic cations, preferably containing long alkyl chain(s), which are exchanged with the inorganic cations in the clay gallery. This article provides a comprehensive review on the strategies for clay modification using polymeric surfactants or polycations: from the synthesis of such surfactants, through the preparation of the polymerically modified clays, and to the fabrication of the respective polymer nanocomposites and their properties.

Nurse-led clinics reduce severity of childhood atopic eczema: a review of the literature.

BACKGROUND: The increasing prevalence and impact of atopic eczema in children in Western countries such as Australia substantiate the need to evaluate the current management of this illness. It has been well documented that the most important aspects in the management of atopic eczema are to allow adequate time for education and demonstration of treatments. However, current models of healthcare funding restrict the opportunity for patient education during medical consultation times. The contribution of nursing to patient care through nurse-led clinics has significant potential in the management of many common chronic illnesses, although atopic eczema has received minimal attention by researchers to date. OBJECTIVES: To discuss the current clinical management of atopic eczema, and to identify the evidence surrounding the benefits of nurse-led clinics in managing patients with chronic illnesses. METHODS: Systematic searches were undertaken using the Cochrane Library, MedLine, PUBMed and CINAHL from 1995 to 2005. Manual searches of references of retrieved articles identified two additional key studies from 1990 and 1993 which were also included in the review. RESULTS: In total, 22 relevant publications were identified. These included both primary research and descriptive studies that covered the medical management of eczema, patient education and improved patient outcomes. The evidence emerging from the literature indicates that the current management of eczema through doctor-led clinics could be improved, with doctors often lacking the time to offer sufficient patient education to manage chronic illnesses effectively. The literature supports the efficacy of nurse-led clinics in the management of chronic illnesses. The benefits of nurse-led clinics include increased patient satisfaction, longer consultations resulting in improved patient education and similar health outcomes when compared with care from a doctor. No studies were identified comparing nurse-led and doctor-led clinics in the management of eczema. CONCLUSIONS: The most effective way to manage atopic eczema is to provide adequate time for education and demonstration of treatments, which the literature suggests can be achieved through nurse-led clinics. The literature review supports an investigation researching the outcomes of a nurse-led clinic on reducing the severity of eczema in children.

Governing the surgical count through communication interactions: implications for patient safety.

BACKGROUND: Intermittently, the incidence of retained surgical items after surgery is reported in the healthcare literature, usually in the form of case studies. It is commonly recognised that poor communication practices influence surgical outcomes. AIM: To explore the power relationships in the communication between nurses and surgeons that affect the conduct of the surgical count. METHODS: A qualitative, ethnographic study was undertaken. Data were collected in three operating room departments in metropolitan Melbourne, Australia. 11 operating room nurses who worked as anaesthetic, instrument and circulating nurses were individually observed during their interactions with surgeons, anaesthetists, other nurses and patients. Data were generated through 230 h of participant observation, 11 individual and 4 group interviews, and the keeping of a diary by the first author. A deconstructive analysis was undertaken. RESULTS: Results are discussed in terms of the discursive practices in which clinicians engaged to govern and control the surgical count. The three major issues presented in this paper are judging, coping with normalisation and establishing priorities. CONCLUSIONS: The findings highlight the power relationships between members of the surgical team and the complexity of striking a balance between organisational policy and professional judgement. Increasing professional accountability may help to deal with the issues of normalisation, whereas greater attention needs to be paid to issues of time management. More sophisticated technological solutions need to be considered to support manual counting techniques.

Perspectives of a nurse, a social worker and a psychiatrist regarding patient assessment in acute inpatient psychiatry settings: a case study approach.

This case study explores what informs and organizes the assessment of patients, as undertaken by a nurse, a social worker and a psychiatrist in public, metropolitan, acute mental health service settings. The research data are the transcripts of in-depth interviews with three experienced practitioners, one from each of the three disciplines. The analysis draws on Foucauldian concepts: discourse as constructed through practices of discipline and the gaze. We explored examples of taken-for-granted assessment practices and their interplay with discourse. The findings suggest that participating practitioners use language in assessment in ways that support the powerful discourses of the professional disciplines. The competing discourse of management, associated with industry and economics, is evident in hospital admission processes, dictating the times and places of assessment. Professional and management discourses both effectively marginalize the perspective of another player in assessment, the patient.

Segmental dynamics of polymers in nanoscopic confinements, as probed by simulations of polymer/layered-silicate nanocomposites.

In this paper we review molecular modeling investigations of polymer/layered-silicate intercalates, as model systems to explore polymers in nanoscopically confined spaces. The atomic-scale picture, as revealed by computer simulations, is presented in the context of salient results from a wide range of experimental techniques. This approach provides insights into how polymeric segmental dynamics are affected by severe geometric constraints. Focusing on intercalated systems, i.e. polystyrene (PS) in 2 nm wide slit-pores and polyethylene-oxide (PEO) in 1 nm wide slit-pores, a very rich picture for the segmental dynamics is unveiled, despite the topological constraints imposed by the confining solid surfaces. On a local scale, intercalated polymers exhibit a very wide distribution of segmental relaxation times (ranging from ultra-fast to ultra-slow, over a wide range of temperatures). In both cases (PS and PEO), the segmental relaxations originate from the confinement-induced local density variations. Additionally, where there exist special interactions between the polymer and the confining surfaces ( e.g., PEO) more molecular mechanisms are identified.

The origins of fast segmental dynamics in 2 nm thin confined polymer films.

Molecular-Dynamics computer simulations were used to study 2 nm wide polystyrene films confined in slit pores, defined by inorganic crystalline surfaces. The simulated systems mimic experimentally studied hybrid materials, where polystyrene is intercalated between mica-type, atomically smooth, crystalline layers. A comparison between the experimental findings and the simulation results aims at revealing the molecular origins of the macroscopically observed behavior, and thus provide insight about polymers in severe/nanoscopic confinements, as well as polymers in the immediate vicinity of solid surfaces. Pronounced dynamic inhomogeneities are found across the 2 nm thin film, with fast relaxing moieties located in low local density regions throughout the film. The origins of this behavior are traced to the confinement-induced density inhomogeneities, which are stabilized over extended time scales by the solid surfaces.

The interplay of knowledge and decision making between nurses and doctors in critical care.

This paper explores the complex interrelationships between knowledge and decision making as nurses and doctors interacted with each other in a critical care unit, which comprised a combined general intensive care and cardiothoracic surgical unit. The critical ethnographic study upon which this paper is based, involved a research group of six nurses who worked in the unit. Nurses differentially valued their knowledge, depending on the situation, experience and level of medical input. They were also involved in decision making based on their differential visibility in the process. Nurses' specialised knowledge of the critical care unit played a major role in influencing how they interacted during decision making.

Rethinking ethnography: reconstructing nursing relationships.

AIMS OF THE STUDY: Critical ethnography is being adopted increasingly by nurses as a legitimate form of research methodology. This paper explores the research practices and dilemmas that emerge from this methodology using a recently completed ethnographic study of nurse-nurse and nurse-doctor interactions in a critical care hospital setting. BACKGROUND: Critical ethnography provides a useful methodology that facilitates mutual dialogue among participants. It may be limited, however, by the central role of researchers and by a tendency to negotiate participants' realities according to a particular 'truth'. These concerns have been strongly critiqued by poststructuralists using concepts such as discourse, subjectivity and power. By incorporating the notion of a poststructural analysis into critical ethnography, researchers are in a position to examine critically the tensions in their own practices, and their struggles with documenting and analysing ethnographic accounts. DESIGN: Six registered nurses comprised the participants of the research group. Through the method of professional journalling, the first author of this paper explored her professional interactions with doctors and other nurses in her role as a nurse in the critical care setting under investigation. Other methods included participant observation, and individual and focus group interviews with nurse participants. ISSUES OF METHODOLOGICAL CONCERN: This paper considers three issues of methodological concern: researcher/participant subjectivity; the movement from empowerment to reflexivity and the construction of one form of ethnographic 'truth'. These issues are discussed in reference to the research relationships with the nurse participants and the process of analysing ethnographic accounts. CONCLUSIONS: In working with critical ethnography using a poststructural analysis, we were able to generate valuable insights about previously hidden areas of relationships among nurse participants in a research group during all stages of the research process. It also provided a means of informing the analysis of ethnographic texts.

Nurses and doctors communicating through medication order charts in critical care.

The structure and content of written forms of communication dynamically interact with the social and historical conditions underlying critical care nursing activities. One important form of documentation regularly used in the critical care area is the medication order chart. This paper considers the ways in which medication order charts are used to structure interactions among nurses and between nurses and doctors. The critical ethnographic study upon which this paper is based involved a research group of six nurses who worked in one critical care unit. Data collection methods involved professional journalling, participant observation and individual and focus group interviews. Data analysis identified four major issues for consideration: imbalance between medical knowledge and legal authority; the nurse as go-between and medication expert; coaching the doctor; and the self policing nurse. The critical care nurse's role extends beyond the traditional passive activity of medication administration. By exploring the power relations underlying this role, there is greater opportunity for improved nursing relationships and patient care.

Acute pain management: implications of scientific evidence for nursing practice in the postoperative context.

Unrelieved acute pain remains prevalent in hospitalized patients despite advances in pain management. A decade after the Australian National Health and Medical Research Council called for improved pain management practices by health professionals, it released clinical guidelines to provide clinicians with current scientific evidence to augment their clinical decision-making. This paper examines the implications of national guidelines on nursing practice and highlights the inadequacies of current implementation policies. Pain management guidelines have failed to decrease patients' postoperative pain because organizations and researchers have ignored the impact of contextual influences on clinicians' decision-making. It is recommended that for successful implementation of national guidelines to occur at the local level of practice, organizations must assist clinicians to identify local influences on their decision-making, to address the issues specific to their own work environment and to evaluate any changes in practice.

Nurse-doctor interactions during critical care ward rounds.

This paper describes the participation of critical care nurses in ward rounds, and explores the power relations associated with the ways in which nurses interact with doctors during this oral forum of communication. The study comprised a critical ethnographic study of six registered nurses working in a critical care unit. Data collection methods involved professional journalling, participant observation, and individual and focus group interviews with the six participating nurses. Findings demonstrated that doctors used nurses to supplement information and provide extra detail about patient assessment during ward rounds. Nurses experienced enormous barriers to participating in decision-making activities during ward round discussions. By challenging the different points of view that doctors and nurses might hold about the ward round process, the opportunity exists for enhanced participation by nurses.

Formative evaluation of a computer-assisted learning program in pharmacology for nursing students.

Previous literature on evaluation of computer-assisted learning (CAL) programs has generally not emphasized the importance of evaluation during the design and development phases. A tendency toward an objective model of evaluation rather than a naturalistic model has also meant that there is little consideration given to the context in which students learn. The aim of this study was to demonstrate the benefits of using a combination of objective and naturalistic models when undertaking a formative evaluation of a computer-assisted learning program. During the design and development phases, the program, Pharmacology Resource for Nurses (PRN), was evaluated using observation of student pairs, student questionnaires, and student focus group interviews to address the complex issues underlying program effectiveness. This study confirmed the importance and value of collecting a variety of evaluation data in order to produce a useful learning program for students.
