A concept analysis of family caregivers' uncertainty of patient's illness

AIM

To analyze and examine the concept of uncertainty of the patient's illness among family caregivers.

BACKGROUND

Promoting family caregivers' health is significant in nursing. Family caregivers may experience uncertainty related to their loved ones' illness. A lack of clarity exists regarding the uncertainty concept among family caregivers and its implications in nursing.

DATA SOURCE

A review of the literature that focused on family caregivers of adult patients using PubMed, CINAHL, and Scopus databases was completed.

METHODS

The Walker and Avant framework was applied to identify the attributes, antecedents, and consequences of family caregivers' uncertainty.

RESULTS

Eight articles were analyzed. Attributes of family caregivers' uncertainty included the patient's illness probability and family caregivers' perception of the illness. Antecedents included the characteristics of the patient's illness, factors associated with the family caregivers' perception of the illness, and family responsibilities of caregiving. The consequences included family caregivers' emotional, psychological, and financial outcomes. Family caregivers' uncertainty is defined as the perception of the inability to process information regarding the patient's illness trajectory when caring for significant others' illness.

CONCLUSIONS

Individuals can perceive uncertainty differently as a patient-facing uncertainty in illness versus a family caregiver facing uncertainty of their loved ones' illness.

Curiosity in Online Video Concept Learning and Short-Term Outcomes in Blended Medical Education

Background: A student's level of curiosity in a subject after learning about it through online videos has not been addressed well in the medical education field. The purpose of this study, therefore, was to investigate online learning's effect on the stimulation of curiosity and short-term learning outcomes in a blended framework of precision medical education.

Methods: A mixed-methods research design was used. During the 2020 academic year, all fifth-year medical students who, prior to class, viewed 6 video clips that presented 6 core concepts were invited to complete a survey and self-reflection on their learning process to assess their level of curiosity in each concept. For each group of medical students, teaching assistants helped collect anonymous survey data and summative assessment scores representing the students' learning outcomes. Video-viewing patterns, attained through an action log transformation, were also coded for analysis. Mann–Whitney U and Kruskal–Wallis tests were employed to compare differences between groups, and multiple linear regression was used to select the factors affecting learning outcomes. Qualitative data were content-coded through a descriptive approach using thematic analysis.

Results: Of 142 medical students, 136 watched the online videos, 124 responded to the questionnaires, and 92 provided comments. Students' curiosity levels after learning about each concept through online videos significantly correlated with the degree to which a concept was learned. Medical students spent a median of 1.6 h online, and pause frequency correlated with curiosity in certain concepts. Aroused curiosity was associated with short-term learning outcomes in inconsistent effect sizes and directions. Students' feedback revealed various dimensions of curiosity, including novelty acknowledgment, recognition of an information gap, and information-seeking requests.

Conclusions: Curiosity can be induced through online video learning platforms and has a role in short-term learning outcomes in medical education.

[FORMATION OF THE NOTION OF «QUALITY OF LIFE», CONCEPTUALISATION AND METHODOLOGICAL ASPECTS (LITERATURE REVIEW)]

Quality of life (QoL) is an important health outcome and represents the primary aim of all medical interventions. The term QoL has been is frequently used in medical and philosophical literature in recent decades and has become an important concept and goal of public health research. Traditionally, biomedical results rather than QoL were the basic endpoints in clinical and public health research. However, recent research is increasingly focusing on the study of QoL in patients and the making use of QoL assessment has increased considerably. The concept of QoL has led to extensive research and has been used by the professional medical community in the treatment of a broad array of diseases. Literature search methods included database searches Scopus, Web of Science, MedLine, the Cochrane Library. Historical trends in the concept of QoL are discussed in this article and issues related to the conceptual and methodological aspects of constructing QoL in the context of health care.

Integrating Sex/Gender into Environmental Health Research: Development of a Conceptual Framework

There is a growing awareness about the need to comprehensively integrate sex and gender into health research in order to enhance the validity and significance of research results. An in-depth consideration of differential exposures and vulnerability is lacking, especially within environmental risk assessment. Thus, the interdisciplinary team of the collaborative research project INGER (integrating gender into environmental health research) aimed to develop a multidimensional sex/gender concept as a theoretically grounded starting point for the operationalization of sex and gender in quantitative (environmental) health research. The iterative development process was based on gender theoretical and health science approaches and was inspired by previously published concepts or models of sex- and gender-related dimensions. The INGER sex/gender concept fulfills the four theoretically established prerequisites for comprehensively investigating sex and gender aspects in population health research: multidimensionality, variety, embodiment, and intersectionality. The theoretical foundation of INGER's multidimensional sex/gender concept will be laid out, as well as recent sex/gender conceptualization developments in health sciences. In conclusion, by building upon the latest state of research of several disciplines, the conceptual framework will significantly contribute to integrating gender theoretical concepts into (environmental) health research, improving the validity of research and, thus, supporting the promotion of health equity in the long term.

[The organizational culture of medical organizations as a factor of carrier orientations of medical personnel]

The problems of professional advancement of medical personnel, their professional formation and professional career have enduring importance in connection with development and improvement of medical care system in any society. The purpose of the study is to investigate characteristics of influence of type of organizational culture of medical organizations on career orientations of medical personnel. The study covered sampling of 7 364 employees of medical organizations. The complex of psycho-diagnostic techniques was applied that permitted to examine prevailing type of organizational culture of medical organizations (The R. Harrison questionnaire adapted by S. A. Lipatov), preferences of medical personnel in building up their professional career (E. Schein questionnaire "Carrier Anchors"), and their concepts about competitive medical worker (semantic differential - 16 opposite personality characteristics). The statistical methods included standard procedures of primary mathematical processing of empirical data (frequency and percentage distribution, calculation of mean group indices, standard deviation and dispersions), comparative analysis using Student's test (correctness of criterion application was checked by the Libya test), Spearman correlation analysis. It is established that under developed organizational culture of medical organization, its orientations towards task and personality, with team cohesion and high level of value-orientated unity of their members, medical workers have consistency of concepts concerning career and a unity of career orientations targeted to professional competence and service to other people that determines quality of medical care.

Scoping study of definitions and instruments measuring vulnerability in older adults

BACKGROUND

It is important to foster social participation and health equity, especially for older adults in situations of vulnerability. Despite growing interest in vulnerability, there is no consensus regarding how to define or measure this concept. This paper provides an inventory and synthesis of definitions of and instruments measuring vulnerability in older adults.

METHODS

Using a scoping study framework, eight databases (Abstracts in Social Gerontology, Academic Search Complete, AgeLine, CINAHL, MEDLINE, SocINDEX, PsycInfo, Scopus) were searched with relevant keywords [Vulnerab* AND (Concept*, Defin*, Meaning, Terminology, Measurement, Assessment*, Indicator*, Instrument*, Scale*, Questionnaire* OR Test*) AND (Aging, Aging, Elder*, Gerontolog*, Older OR Senior*)].

RESULTS

Thirty-one original definitions and five measuring instruments were identified, content-analyzed, and compared. Vulnerability definitions mostly focused on people under conditions that increased their risk of harm because of individual physical factors, the environment, and their interaction. Considering these definitions, experts in the field of aging, including two representing older adults, participated in a workshop, and a consensus was reached to define a situation of vulnerability as "a set of circumstances in which one or more individuals experience, at a specific moment in time, one or multiple physiological, psychological, socioeconomic or social difficulties that may interact to increase their risk of being harmed or having coping challenges that have a negative impact on their life." Although none of the measures fully targeted this definition, the Perceived Vulnerability Scale (PVS) is one of the most complete measures, with 22 items considering feelings of vulnerability toward personal and environmental factors, and good psychometric properties.

CONCLUSIONS

The proposed definition and the PVS help to provide a common language and measure in health and social sciences research, policy and practice identifying and reaching older adults in situations of vulnerability and intervening to foster social participation and health equity.

Conceptualizing patient participation in psychiatry: A survey describing the voice of patients in outpatient care

BACKGROUND

While increasingly discussed in somatic care, the concept of patient participation remains unsettled in psychiatric care, potentially impeding person-centred experiences.

OBJECTIVE

To describe outpatient psychiatric care patients' conceptualization of patient participation.

DESIGN

An exploratory survey.

SETTING AND PARTICIPANTS

Patients in four psychiatric outpatient care units.

VARIABLES

Patients conceptualized patient participation by completing a semi-structured questionnaire, including optional attributes and free text. Data were analysed using statistics for ordinal data and content analysis for free text.

RESULTS

In total, 137 patients (69% of potential respondents) completed the questionnaire. The discrete items were favoured for conceptualizing patient participation, indicating a primary connotation that participation means being listened to, being in a reciprocal dialogue, learning about one's health care and managing one's symptoms. Additional free-text responses acknowledged the attributes previously recognized, and provided supplementary notions, including that patient participation is about mutual respect and shared trust.

DISCUSSION

What patient participation is and how it can be facilitated needs to be agreed in order to enable preference-based patient participation. Patients in outpatient psychiatric care conceptualize participation in terms of both sharing of and sharing in, including taking part in joint and solo activities, such as a reciprocal dialogue and managing symptoms by yourself.

CONCLUSION

While being a patient in psychiatric care has been associated with a lack of voice, an increased understanding of patient participation enables person-centred care, with the benefits of collaboration, co-production and enhanced quality of care.

PATIENT CONTRIBUTION

Patients provided their conceptualization of patient participation in accordance with their lived experience.

Indeterminate form of Chagas disease: historical, conceptual, clinical, and prognostic aspects

Chagas disease (CD) remains a serious endemic disease in Latin America and a major public health problem. Because of globalization, the disease has spread to non-endemic areas in the northern hemisphere. In the chronic phase of the disease, most patients present with the indeterminate form (IF), characterized by positive serology for Trypanosoma cruzi, absence of clinical findings, and normal findings in electrocardiogram (ECG). IF was not recognized as a clinical entity until decades after the discovery of the disease, and only in the 1940-50s, it was categorized as a form of CD, and its conceptual definition was ratified in the 1980s. Children, adolescents, and young adults with the IF benefit from etiological treatment and tend to have less progression to heart disease in the long term than the untreated ones. IF patients have an essentially benign clinical condition, and their prognosis can be compared to that of healthy individuals with normal ECG findings. Currently, because of aging, patients with the IF have comorbidities that require attention in health services.

Development of a Search Task Using Immersive Virtual Reality: Proof-of-Concept Study

BACKGROUND

Serious games are gaining increasing importance in neurorehabilitation since they increase motivation and adherence to therapy, thereby potentially improving its outcome. The benefits of serious games, such as the possibility to implement adaptive feedback and the calculation of comparable performance measures, can be even further improved by using immersive virtual reality (iVR), allowing a more intuitive interaction with training devices and higher ecological validity.

OBJECTIVE

This study aimed to develop a visual search task embedded in a serious game setting for iVR, including self-adapting difficulty scaling, thus being able to adjust to the needs and ability levels of different groups of individuals.

METHODS

In a two-step process, a serious game in iVR (bird search task) was developed and tested in healthy young (n=21) and elderly (n=23) participants and in a group of patients with impaired visual exploration behavior (ie, patients with hemispatial neglect after right-hemispheric stroke; n=11). Usability, side effects, game experience, immersion, and presence of the iVR serious game were assessed by validated questionnaires. Moreover, in the group of stroke patients, the performance in the iVR serious game was also considered with respect to hemispatial neglect severity, as assessed by established objective hemispatial neglect measures.

RESULTS

In all 3 groups, reported usability of the iVR serious game was above 4.5 (on a Likert scale with scores ranging from 1 to 5) and reported side effects were infrequent and of low intensity (below 1.5 on a Likert scale with scores ranging from 1 to 4). All 3 groups equally judged the iVR serious game as highly motivating and entertaining. Performance in the game (in terms of mean search time) showed a lateralized increase in search time in patients with hemispatial neglect that varied strongly as a function of objective hemispatial neglect severity.

CONCLUSIONS

The developed iVR serious game, "bird search task," was a motivating, entertaining, and immersive task, which can, due to its adaptive difficulty scaling, adjust and be played by different populations with different levels of skills, including individuals with cognitive impairments. As a complementary finding, it seems that performance in the game is able to capture typical patterns of impaired visual exploration behavior in hemispatial neglect, as there is a high correlation between performance and neglect severity as assessed with a cancellation task.

[Conception and framework of land ecological restoration for a new stage in China.]

Based on the theories of geography and landscape ecology, land ecological restoration is an important strategy to promote ecological civilization and build a beautiful China. Land ecological restoration in China has the characteristics of multi-disciplinary theoretical system, diverse work mode, integration of technology and methods, and diversified practice and exploration. The overall effectiveness of the work coexists with arduous tasks. Based on the new challenges in land ecological restoration, we summarized the overall framework and technical path of land ecological restoration, the working mechanism and mode of regional land ecological restoration, the content system and technical standards of land ecological restoration. In the new stage, the top-level design of land ecological restoration in China should focus on the work system, business boundary and institutional system, identify the responsibility boundary of different business processes, and realize the closed management of the whole work chain from the perspective of theory, system, engineering and technology. Rural settlement area, urban built-up area, industrial and mining gathering area, ecological function area and blue ocean area are the five major elements of regional scale land space, which correspond to five different ecological restoration modes, namely, comprehensive land improvement, urban renewal and double repair, mine geological environment restoration, mountain-river-forest-farmland-lake-grassland restoration, and blue bay restoration. It is necessary to comprehensively use the thinking of "Three Integrations" (information, technology, and process) to build a set of regional land ecological restoration work mode covering the integration of investigation, monitoring and evaluation, land space planning, project implementation, project acceptance and ecosystem monitoring and evaluation.

The evolution of the concept of stress and the framework of the stress system

Stress is a central concept in biology and has now been widely used in psychological, physiological, social, and even environmental fields. However, the concept of stress was cross-utilized to refer to different elements of the stress system including stressful stimulus, stressor, stress response, and stress effect. Here, we summarized the evolution of the concept of stress and the framework of the stress system. We find although the concept of stress is developed from Selye's "general adaptation syndrome", it has now expanded and evolved significantly. Stress is now defined as a state of homeostasis being challenged, including both system stress and local stress. A specific stressor may potentially bring about specific local stress, while the intensity of stress beyond a threshold may commonly activate the hypothalamic-pituitary-adrenal axis and result in a systematic stress response. The framework of the stress system indicates that stress includes three types: sustress (inadequate stress), eustress (good stress), and distress (bad stress). Both sustress and distress might impair normal physiological functions and even lead to pathological conditions, while eustress might benefit health through hormesis-induced optimization of homeostasis. Therefore, an optimal stress level is essential for building biological shields to guarantee normal life processes.

Definitions and Operationalization of Mental Health Problems, Wellbeing and Participation Constructs in Children with NDD: Distinctions and Clarifications

Children with impairments are known to experience more restricted participation than other children. It also appears that low levels of participation are related to a higher prevalence of mental health problems in children with neurodevelopmental disorders (NDD). The purpose of this conceptual paper is to describe and define the constructs mental health problems, mental health, and participation to ensure that future research investigating participation as a means to mental health in children and adolescents with NDD is founded on conceptual clarity. We first discuss the difference between two aspects of mental health problems, namely mental disorder and mental illness. This discussion serves to highlight three areas of conceptual difficulty and their consequences for understanding the mental health of children with NDD that we then consider in the article: (1) how to define mental health problems, (2) how to define and assess mental health problems and mental health, i.e., wellbeing as separate constructs, and (3) how to describe the relationship between participation and wellbeing. We then discuss the implications of our propositions for measurement and the use of participation interventions as a means to enhance mental health (defined as wellbeing). Conclusions: Mental disorders include both diagnoses related to impairments in the developmental period, i.e., NDD and diagnoses related to mental illness. These two types of mental disorders must be separated. Children with NDD, just like other people, may exhibit aspects of both mental health problems and wellbeing simultaneously. Measures of wellbeing defined as a continuum from flourishing to languishing for children with NDD need to be designed and evaluated. Wellbeing can lead to further participation and act to protect from mental health problems.

A Chinese Conceptual Semantic Feature Dataset (CCFD)

Memory and language are important high-level cognitive functions of humans, and the study of conceptual representation of the human brain is a key approach to reveal the principles of cognition. However, this research is often constrained by the availability of stimulus materials. The research on concept representation often needs to be based on a standardized and large-scale database of conceptual semantic features. Although Western scholars have established a variety of English conceptual semantic feature datasets, there is still a lack of a comprehensive Chinese version. In the present study, a Chinese Conceptual semantic Feature Dataset (CCFD) was established with 1,410 concepts including their semantic features and the similarity between concepts. The concepts were grouped into 28 subordinate categories and seven superior categories artificially. The results showed that concepts within the same category were closer to each other, while concepts between categories were farther apart. The CCFD proposed in this study can provide stimulation materials and data support for related research fields. All the data and supplementary materials can be found at https://osf.io/ug5dt/ .

Disease Concept-Embedding Based on the Self-Supervised Method for Medical Information Extraction from Electronic Health Records and Disease Retrieval: Algorithm Development and Validation Study

BACKGROUND

The electronic health record (EHR) contains a wealth of medical information. An organized EHR can greatly help doctors treat patients. In some cases, only limited patient information is collected to help doctors make treatment decisions. Because EHRs can serve as a reference for this limited information, doctors' treatment capabilities can be enhanced. Natural language processing and deep learning methods can help organize and translate EHR information into medical knowledge and experience.

OBJECTIVE

In this study, we aimed to create a model to extract concept embeddings from EHRs for disease pattern retrieval and further classification tasks.

METHODS

We collected 1,040,989 emergency department visits from the National Taiwan University Hospital Integrated Medical Database and 305,897 samples from the National Hospital and Ambulatory Medical Care Survey Emergency Department data. After data cleansing and preprocessing, the data sets were divided into training, validation, and test sets. We proposed a Transformer-based model to embed EHRs and used Bidirectional Encoder Representations from Transformers (BERT) to extract features from free text and concatenate features with structural data as input to our proposed model. Then, Deep InfoMax (DIM) and Simple Contrastive Learning of Visual Representations (SimCLR) were used for the unsupervised embedding of the disease concept. The pretrained disease concept-embedding model, named EDisease, was further finetuned to adapt to the critical care outcome prediction task. We evaluated the performance of embedding using t-distributed stochastic neighbor embedding (t-SNE) to perform dimension reduction for visualization. The performance of the finetuned predictive model was evaluated against published models using the area under the receiver operating characteristic (AUROC).

RESULTS

The performance of our model on the outcome prediction had the highest AUROC of 0.876. In the ablation study, the use of a smaller data set or fewer unsupervised methods for pretraining deteriorated the prediction performance. The AUROCs were 0.857, 0.870, and 0.868 for the model without pretraining, the model pretrained by only SimCLR, and the model pretrained by only DIM, respectively. On the smaller finetuning set, the AUROC was 0.815 for the proposed model.

CONCLUSIONS

Through contrastive learning methods, disease concepts can be embedded meaningfully. Moreover, these methods can be used for disease retrieval tasks to enhance clinical practice capabilities. The disease concept model is also suitable as a pretrained model for subsequent prediction tasks.

Considerations on the concept, definition, and diagnosis of amyotrophic lateral sclerosis

The concept, definition, and diagnosis of amyotrophic lateral sclerosis (ALS) currently present some problems. This article systematically reviews the literature on the history, current concepts, definition, and diagnosis of ALS, and discloses the present problems based on the retrieved literature and the authors’ clinical experience. The current concepts and definitions of ALS have not yet been unified or standardized in clinical practice, and are sometimes vague or inaccurate, which can cause difficulties for neurologists in the clinical treatment of ALS. The concept and definition of ALS need to be further ascertained, and the current diagnostic criteria for ALS require further development. The identification of effective and objective biomarkers may be a feasible method for the early and accurate diagnosis of ALS. Therefore, future research should focus on the identification of reliable biomarkers—especially neuroimaging biomarkers—through autopsy. Standardizing the concept and definition of ALS and formulating clear diagnostic criteria will largely avoid many uncertainties in the future clinical research and treatment of ALS, which will greatly benefit patients.

[About experience of developing concept of personnel policy in health care at the level of the subject of the Russian Federation]

The personnel policy is one of priority areas of developing national health care. Its effective implementation requires evidence-based development of relevant program documents, the most important of which is the Concept of health care personnel policy that currently exists only in a number of regions of the Russian Federation. In this regard, the purpose of the study was to develop approaches to scientific justification and development of the Concept of health care personnel policy at the level of region of the Russian Federation, as exemplified in the Irkutsk oblast. The article describes progress of this large-scale and lengthy study, its main results included. The developed approaches resulted in comprehensive organizational technology of development corresponding Concept. The results of this experience can be implemented in other regions of the Russian Federation. Therefore, it is of scientific and practical interest for all potential developers of similar program documents and wide range of specialists in health care organization.

Dealing with dysnomia: Strategies for the cultivation of used concepts in social research

This article follows recent calls to turn social theory away from its fixations on intellectual history and toward the mechanics and craft of creating social theories in the research process. The subject of this article is a dilemma common to theorizing in social science: dysnomia, or the phenomenon in which some object is poorly named. Specifically, this article focuses on how social scientists distinguish original concepts from their equivalents in everyday speech. Three tactics for dealing with dysnomia are named-academic arcana, classification and sociologism-and considered in order to ascertain the strengths and weaknesses of each.

Patients and Health Professional's Perspective of Functional Mobility in Parkinson's Disease

Background: Functional mobility (FM) is the person's ability to move to accomplish daily living tasks and activities. FM limitations are common in Parkinson's disease, increase with disease progression, and can be highly disabling. Although several studies in Parkinson's disease (PD) field use this concept, only recently, a formal definition has been proposed.

Objective: We aimed to explore patient's and health professional's perspectives of FM in PD.

Methods: A focus group methodology has been used. Four focus groups, with a total of 10 patients and 10 health professionals, were performed. Six patients were early stage and four advanced stage. The health professional's group was composed of five neurologists and five physiotherapists. The suitability of the new concept, the impact of FM limitations in PD patient's daily routine, and the potential benefit of walking aids have been discussed.

Results: All participants were able to provide a spontaneous definition of FM, matching with the proposed concept. All agreed that PD affects patient's FM, increasing the limitations with disease progression, and with the existence of a serious prejudice with walking aids that hinders its use. Early-stage patient's perspective seems to be more in line with neurologist's perspective, while the views of advanced-stage patients were closer to physiotherapist's views.

Conclusion: FM concept was considered as intuitive and useful. FM limitations have an important physical and social impact in the advanced stage of the disease. Although patients and health professionals acknowledge walking aid's benefit improving patient's FM, the prejudice associated with this type of tools limits its recommendation and use.

Conceptual principles and patterns of legal regulation of the processes of storage, access and data protection of genome sequencing in foreign countries as the basis for the modernization of Russian legislation

The relevance of the study of the general principles and patterns of legal regulation of access storage processes and data protection of genome sequencing in foreign countries is determined by the need to develop a general concept of legal regulation of this type of activity in Russia. The purpose of this study is to develop the system-forming principles and patterns of access storage and data protection of genome sequencing in Russia. To achieve this goal, tasks were set and solved to identify and study the general principles and patterns of legal regulation of access storage processes and data protection of genome sequencing in foreign countries. The international documents regulating the features of regulation of access storage processes and data protection of genome-wide sequencing, the doctrinal sources of Great Britain, the USA, France, Israel, and Japan are studied. Methods used: general philosophical, general scientific, private scientific, special (structural-legal, comparative-legal, formal-legal). The general principles for the formation of the concept of legal regulation of genome sequencing in Russia are proposed. It was revealed that the creation of a universal regulatory regulator aimed at protecting the subject of personal data in view of the prevalence of public interests over private ones and the constant expansion of the scope of application of genetic data obtained as a result of genome-wide sequencing is the main problem in developing a legal regulation mechanism in the studied area. For the first time, the authors determine the basic principles for developing the concept of genome-wide sequencing in Russia, including: recognition of human rights and human dignity as the highest value, the necessity of researchers' responsibility for the well-being of participants in view of the obtained research results, the mandatory informed consent of which should be voluntary, permanent, their right to get acquainted with the results obtained if it concerns their health, access to such information, ensuring the right to non-knowledge of research results and others.

Paradoxes of person-centred care: A discussion paper

Aim

Previous research has mainly focused on the advantages of PCC and less on its disadvantages. Hence, there is a need to further explore the recent research regarding PCC from both sides. Therefore, the aim of this paper is to elucidate the advantages and disadvantages of PCC.

Design

Discussion paper.

Methods

We searched relevant literature published January 2000-March 2018 in PubMed, Medline, CHINAL, Scopus and Web of Science.

Results

The results showed that PCC can contribute to improved health and well-being, improved mutual interaction in relationships, improved cost-effectiveness and improved work environment, while the disadvantages can involve increased personal and financial costs, exclusion of certain groups, increased personal and financial costs, exclusion of staff's personhood and unfairness due to empathy. An analysis of the existing literature on PCC showed paradoxes, which call for further investigation.

Six decades of lateral flow immunoassay: from determining metabolic markers to diagnosing COVID-19

Technologies based on lateral flow immunoassay (LFIA), known in some countries of the world as immunochromatographic tests, have been successfully used for the last six decades in diagnostics of many diseases and conditions as they allow rapid detection of molecular ligands in biosubstrates. The popularity of these diagnostic platforms is constantly increasing in healthcare facilities, particularly those facing limited budgets and time, as well as in household use for individual health monitoring. The advantages of these low-cost devices over modern laboratory-based analyzers come from their availability, opportunity of rapid detection, and ease of use. The attractiveness of these portable diagnostic tools is associated primarily with their high analytical sensitivity and specificity, as well as with the easy visual readout of results. These qualities explain the growing popularity of LFIA in developing countries, when applied at small hospitals, in emergency situations where screening and monitoring health condition is crucially important, and as well as for self-testing of patients. These tools have passed the test of time, and now LFIA test systems are fully consistent with the world's modern concept of ‘point-of-care testing’, finding a wide range of applications not only in human medicine, but also in ecology, veterinary medicine, and agriculture. The extensive opportunities provided by LFIA contribute to the continuous development and improvement of this technology and to the creation of new-generation formats. This review will highlight the modern principles of design of the most widely used formats of test-systems for clinical laboratory diagnostics, summarize the main advantages and disadvantages of the method, as well as the current achievements and prospects of the LFIA technology. The latest innovations are aimed at improving the analytical performance of LFIA platforms for the diagnosis of bacterial and viral infections, including COVID-19.

[The comparative evaluation of policy documents of the Russian Federation concerning personnel policy in health care]

Nowadays, in Russia number of problems is present in effective personnel policy in health care. The National Concept of personnel policy in health care (2002) expired in 2010 and no new one was developed. However, corresponding program documents were adopted at the level of subjects of the Russian Federation. The purpose of study was to compare evaluation of program documents of subjects of the Russian Federation related to issues of personnel policy in health care. The continuous sampling technique was applied to study these documents, which were valid in the territories of all subjects of the Russian Federation in 2002-2019. The comparative assessment was performed. It is demonstrated that the most informative document in this area is only the corresponding specialized Concept. However, this document was adopted only in 8.2% of the subjects of the Russian Federation, and they were valid only in two subjects. The concepts of health care development in the subjects of the Russian Federation, addressing medical personnel policy were adopted in 44.7% of the subjects of the Russian Federation. However, these legal documents operate only in 15.3% of territories. At the same time, the availability of appropriate specialized program document is a prerequisite of development of coherent and effective medical personnel policy in health care at all its levels.

Vulnerability in birth: A negative capability

AIM

This article explores the literature on women's expectations for birth, the sociocultural context from which these expectations originate and their impact on the interpretation of birth experience.

BACKGROUND

Childbirth is associated with specific expectations from women with the potential for dissatisfaction if these expectations are not met.

DESIGN

This paper presents a systematic analysis of the concept of vulnerability in childbirth.

FINDINGS

A framework was extracted from the literature that linked the themes of a discourse of control, construction of inadequacy and shame of exposure to explain the sociocultural origin of dominant childbirth expectations in the literature. The experience of vulnerability unique to the birthing event is suggested as exposing the woman to this underlying contextual framework and impacting the interpretation of her birth.

CONCLUSION

This synthesis has exposed the transient experience of vulnerability during birth as a significant contributor to the birthing woman's interpretation of the birth and her place within it.

RELEVANCE TO CLINICAL PRACTICE

An explanatory framework is offered to clinicians that could increase their awareness of sociocultural and historical factors impacting a woman's expectations for birth. Appreciation of the woman's vulnerability in birth, exposing her to the influence of this framework, can assist clinicians to facilitate a quality birth experience for women. Furthermore, supporting women and midwives to accept this experience of birth vulnerability as a "negative capability," can facilitate an empowering birth experience.

Key components of shared decision making models: a systematic review

OBJECTIVES

To (1) provide an up-to-date overview of shared decision making (SDM)-models, (2) give insight in the prominence of components present in SDM-models, (3) describe who is identified as responsible within the components (patient, healthcare professional, both, none), (4) show the occurrence of SDM-components over time, and (5) present an SDM-map to identify SDM-components seen as key, per healthcare setting.

DESIGN

Systematic review.

ELIGIBILITY CRITERIA

Peer-reviewed articles in English presenting a new or adapted model of SDM.

INFORMATION SOURCES

Academic Search Premier, Cochrane, Embase, Emcare, PsycINFO, PubMed, and Web of Science were systematically searched for articles published up to and including September 2, 2019.

RESULTS

Forty articles were included, each describing a unique SDM-model. Twelve models were generic, the others were specific to a healthcare setting. Fourteen were based on empirical data, 26 primarily on analytical thinking. Fifty-three different elements were identified and clustered into 24 components. Overall, Describe treatment options was the most prominent component across models. Components present in >50% of models were: Make the decision (75%), Patient preferences (65%), Tailor information (65%), Deliberate (58%), Create choice awareness (55%), and Learn about the patient (53%). In the majority of the models (27/40), both healthcare professional and patient were identified as actors. Over time, Describe treatment options and Make the decision are the two components which are present in most models in any time period. Create choice awareness stood out for being present in a markedly larger proportion of models over time.

CONCLUSIONS

This review provides an up-to-date overview of SDM-models, showing that SDM-models quite consistently share some components but that a unified view on what SDM is, is still lacking. Clarity about what SDM constitutes is essential though for implementation, assessment, and research purposes. A map is offered to identify SDM-components seen as key.
