Increased magnetic resonance imaging in prostate cancer management-What are the outcomes?

RATIONALE

Increased attention to cancer care has instigated altered systems for screening, diagnosis, and management of various types of cancer, such as in the prostate. While such systems very likely have improved the quality of cancer care, they also result in the altered use of specific services, such as magnetic resonance imaging (MRI).

AIMS AND OBJECTIVE

To study the change in the use of prostate MRI in the Norwegian health care system from 2013 to 2021 and to investigate some reasons for and potential implications of this change.

METHOD

Data from the Norwegian Health Economics Administration (HELFO), The Cancer Registry of Norway and Cause-of-death registry at the Norwegian Institute of public health and the health registry of Vestfold Hospital Trust were used for descriptive statistical analysis.

RESULTS

The number of MRIs of the prostate increased threefold from 2013 to 2021, representing an extra cost of 2 million USD in 2020. The incidence of prostate cancer was stable at about 5000 cases per year, corresponding to 178 per 100,000 men, indicating no increased overdiagnosis. However, the clinical staging has changed substantially during this period, indicating stage and grade migration. The number of negative biopsies was reduced, and there are three MRIs per reduced negative biopsy. The number of persons on active surveillance increased during the period. However, these changes are partly independent of the increase in the number of MRIs.

CONCLUSION

There was a substantial increase in the number of prostate MRIs and thus an increase in costs. This appears to have contributed to the reduction of negative biopsies, improved staging and increased active surveillance. However, as these effects are partly independent of the increase in MRIs, we need to document the outcomes for patients from prostate MRIs as their opportunity costs are substantial.

From training to education: Understanding and responding to the resuscitation education issues with ideas and theory

BACKGROUND

Alongside medical science, educational efficiency and local implementation have been identified as the three leading themes that influence cardiac arrest survival outcomes. Where the medical science domain continues to inform the contemporary evidence for the optimal practice, the remaining two education themes continue to face criticism linked to the poor sustainability of clinician resuscitation skills, with a rapid decay in abilities often evident soon after training and certification. The European Resuscitation Council recently reasserted the importance of programmes to reflect educational best practices and learning theory.

DISCUSSION

This paper discusses a selection of key contemporary theoretical themes, which directly relate to several specific ongoing education concerns.

RECCOMENDATIONS

Beyond questioning the effectiveness of current conventions to achieve sustainable knowledge and skills for the long term, it is suggested that common approaches may not be sufficient to prepare clinicians or certify competency for the complexities of these future events and that a major pedagogical shift may be required to teaching and assessment.

How precision medicine changes medical epistemology: A formative case from Norway

RATIONALE AND AIMS

Precision medicine (PM) raises a key question: How do we know what works when the number of people with a health problem becomes small or one (n = 1)? We here present a formative case from Norway. The Norwegian Board of Health Supervision was faced with a cancer patient, who had improved after treatment with a drug in the private health sector but was refused continued treatment in the public health service due to lack of clinical trial evidence. The Board overturned this decision, arguing that the drug had been unambiguously documented to work in the individual case. We aim to provide an in-depth analysis of this case and The Board's decision and thereby to illustrate and elucidate key epistemological and ethical issues and developments in PM.

METHOD

We provide our analysis and discussion using tools of critical thinking and concepts from philosophy of science and medicine, such as uncertainty, evidence, forms of inference and causation. We also examine the case in light of the history of evidence-based medicine (EBM).

RESULTS AND DISCUSSION

The case reflects an epistemological shift in medicine where PM puts greater emphasis on evidence that arises in individual patients after the treatment is provided over pre-existing population-based evidence. PM may rely more heavily on abduction to decide what works and qualitative, rather than quantitative judgements. The case also illustrates a possible shift in the concept of causation from regularity accounts to mechanistic and process accounts. We discuss the ethical implications of a shift from more 'traditional' to 'personalised EBM'.

CONCLUSION

A framework that is more based on abductions and evidence arising in the individual case has problems in creating quantifiable, reliable and generalisable evidence, and in promoting transparency and accountability. PM currently lacks clear criteria for deciding what works in an individual, posing ethical challenges.

Common things are common, but what is common? Incorporating probability information into differential diagnosis

The well-known clinical axiom declaring that 'common things are common' attests to the pivotal role of probability in diagnosis. Despite the popularity of this and related axioms, there is no operationalized definition of a common disease, and no practicable way of incorporating actual disease frequencies into differential diagnosis. In this essay, we aim to disambiguate the definition of a common (or rare) disease and show that incidence-not prevalence-is the proper metric of disease frequency for differential diagnosis. We explore how numerical estimates of disease frequencies based on incidence can be incorporated into differential diagnosis as well as the inherent limitations of this method. These concepts have important implications for diagnostic decision making and medical education, and hold promise as a method to improve diagnostic accuracy.

The clinical paradox: Acting in two worlds in parallel

BACKGROUND

Centred around the thesis that for those engaged in clinical practice there are two worlds present in parallel, this article defines the characteristics of the supposed second, qualitative world. Contrasting these characteristics to those of the world as seen in continuous metric dimensions of space and time, we derive the nature of the qualitative elements and their coherent interaction, as well as the rules governing these dynamic elements' interactions.

RESULTS

The second world claimed to exist turns out to be made of individual worlds centred in coherent perspectival interaction. Its polycentric agency enacts individual perspectives and mutual information uptake. This hermeneutical approach conforms with some recent developments in theory, such as that of Nobel Prize winner Elinor Ostrom, or the enactment theory of cognitive science.

CONCLUSIONS

Following this theoretical process, two practical consequences are drawn. The first consists of an advanced model of biopsychosocial interaction, as extensively published throughout the years. The second presents the concept of quality-oriented self-aid groups open to all exposed to or working in care and healthcare. The corresponding training helps practitioners to consciously and deliberately move, perceive, and perform in the duplicity of worlds, the one the conventional quantifying, metric one, the other the mostly rationally unknown world emerging from qualifying interactive agency.

Situating stigma: Accounting for deviancy, difference and categorial relations

This article returns to Goffman's early formulations of 'stigma' in outlining a critique of contemporary social scientific uses and abuses of the concept. We argue that whilst Goffman's discussion of stigma is not without its troubles, it has mostly been approached in a manner that treats the concept outside of an appreciation of stigma as a phenomenon of interaction order. More specifically, we discuss and demonstrate how stigma serves an analytic gloss for social relations observable in social settings and in accounts of difference, deviance and degradation. We analyse both social scientific and lay uses of the stigma concept in relation to care-experienced young children and self-harm to demonstrate the shared categorisational practices and logics that are often obscured through theoretical treatments of stigma. The recommendation is, then, that an attention to 'stigma' in care settings must begin with the conditions in and from which stigma might come to feature as a sense-making device for all parties.

On the definition of stigma

BACKGROUND

There are thousands of papers about stigma, for instance about stigma's impact on wellbeing, mental or physical health. But the definition of stigma has received only modest attention. In "Conceptualizing stigma" from 2001, Link and Phelan offer a thorough and detailed definition of stigma. They suggest that there are six necessary conditions for stigma, namely labelled differences, stereotypes, separation, status loss and discrimination, power, and emotional reaction. This definition is widely applied in the literature but is left mainly uncriticized.

METHOD

We submit the Link and Phelan definition of stigma to a systematic conceptual analysis. We first interpret, analyze and reconsider each of the six components in Link and Phelan's definition of stigma, and on the basis of these analyses, we secondly suggest a revised definition of stigma.

RESULT

The Link and Phelan definition is thorough and detailed, but includes redundant components. These are status loss and discrimination, and emotional reaction.

CONCLUSION

We suggest that groups, not individuals, are the target of stigma, though it is individuals who may be the victims of it. We suggest a revised definition of stigma that is more simple, precise, and consistent with the empirical literature on stigma; there is stigma if and only if there is labelling, negative stereotyping, linguistic separation, and power asymmetry.

The Normativity of Law: Has the Dispositional Model Solved our Problem?

In Legal Directives and Practical Reasons, Noam Gur has presented a novel account, called the dispositional model, to explain how law bears on our normative practical reasons. Gur holds that his model is superior to the current models, namely the standard weighing model and Joseph Raz's exclusionary model. Although his work provides useful insights into the practical impact of law, I argue that: (i) his challenge against the exclusionary model is valid only insofar as one accepts Raz's normal justification thesis and dependence thesis; (ii) his argument against the weighing model misses its target, because it attacks the model as a decision-making method, not as an account of practical reason; and (iii) his dispositional model solely constitutes a decision-making strategy and does not offer a third alternative answer to the question of how law affects our normative practical reasons. Hence, the dispositional model is not a competitor to the weighing and the exclusionary model, and the problem of accounting for the normativity of law remains.

Appealing to Tacit Knowledge and Axiology to Enhance Medical Practice in the COVID-19 Pandemic: A Systematic Review and Hermeneutic Bioethical Analysis

Background: The pressure of coronavirus disease 2019 (COVID-19) pandemic, epidemiological and demographic changes, personnel-patient relationship in healthcare, and the development of biotechnologies do not go unnoticed by the healthcare professional. Changes are so wide and at a high rate that guidelines and mere scientific knowledge, which are represented by evidence-based medicine, are not sufficient to lead actions, thus the experiential aspects in the configuration of an ethos present as a fundamental part of the resources to deal with critical scenarios, such as a pandemic. In this regard, the recognition of tacit knowledge as a way of teaching and learning skills related to ethical aspects such as principles, virtues, and values, revealed as a fundamental part of the clinical field. The challenge is to strengthen binomial evidence-based medicine and values-based in order to achieve excellence in the health care of the patients and the well-being of the clinical personnel.

Method: A 2-fold analysis was conducted taking pediatric endocrinology as an example. First, a systematic review was carried out in electronic databases BIREME, PubMed, and PhilPapers following PEO and PRISMA approaches. A total of 132 articles were garnered. After reading their title and abstract, 30 articles were obtained. Quantitative information was arranged in an Excel database according to three themes: ethics, axiology, and tacit knowledge. A quality criterion that meets our research question was assigned to each article and those which had a quality criterion of 3 (9) were taken to carry out the hermeneutic bioethical analysis, which consisted of three stages, namely naïve reading, codification, and interpretation. The results were analyzed in Atlas.ti. to elucidate the relations between the three main themes in accordance with the objective.

Results: Although there was no difference in the frequency of tacit knowledge skills, including cognitive, social, and technical, for medical practice, there is an intrinsic relationship between epistemic and ethical values with cognitive skills, this means that professionals who practice honesty, authenticity and self-control are capable of seeing patients as persons and thus respect their dignity. This suggested that there is a strong partnership between evidence-based medicine and value-based medicine, which reinforced this binomial as the two feet on which medical practice decisions rested. With regard to tacit knowledge in terms of the context of the COVID-19 pandemic, the challenges refer to (1) adapting and learning a new way of establishing trust with the patient and (2) how to capitalize on the new knowledge that new experiences have posed.

Discussion: The analysis of ethical-tacit knowledge in medicine is a recent phenomenon and is in full development. Although no references were found that dealt with any of the main topics in pediatric endocrinology, there is an interest in pediatrics to explore and discuss educational strategies in ethics related to its tacit dimension as a vector of enhancement in the clinical practice. Educational strategies ought to take into consideration the development of skills that promote reflection and discussion of experiences, even more vigorously in the context of the COVID-19 pandemic.

Clinical decision-making for shoulder surgery referral: An art or a science?

RATIONALE

Decision-making in musculoskeletal health care is complex, with discrepancy among clinical providers and variation in the per cent of referrals for specialist care. To date, there is an increased focus on specialist referrals, risking overuse of expensive testing and contributing to unnecessary treatment.

AIMS AND OBJECTIVES

This report will considerer the difficulties of primary care musculoskeletal decision-making using shoulder injuries as an example, presenting a solution based on multi-criteria decision-making analysis with online software. The associated issues involved in clinical decision-making are complex. Contributing to the components of complexity are; the multifaceted aetiology of shoulders, the experience and knowledge of providers, and the burden of patient demands. Notwithstanding, funding considerations, resource allocation availability and other associated issues around clinical decision-making. Considering the many facets and complexities of clinical decision-making, this is an area where multi-criteria decision-making analysis (MCDM) may be appropriate. The MCDM analysis approach is increasingly being used in health care and can assist in the organizing and weighting of identified key clinical factors. MCDM could be applied to the challenges of musculoskeletal care with the potential to decrease decision-making variability. Furthermore, the significance of each key clinical factor that musculoskeletal decision-making is based on are to date unclear.

CONCLUSION

Therefore, this preliminary report offers a start towards clarifying key factors and an approach for implementing improved shoulder clinical care decision-making which could then be adapted and applied to other body sites.

The multiple faces of practical wisdom in complex clinical practices: An empirical exploration

RATIONALE, AIMS, AND OBJECTIVES

In recent publications, attention has been drawn to the importance of practical wisdom in order to ensure good, individually attuned care in complex clinical practices. However, what remains insufficiently elucidated is how practical wisdom emerges in the workplace. This study aims to describe manifestations of practical wisdom in medical practices within a general hospital. It also seeks to clarify the interruptions that can be considered as triggers for the emergence of practical wisdom. Furthermore, we searched for figurations, which possibly elicit or constrain the emergence of practical wisdom.

METHODS

We used 10 thick descriptions of very distinct patient cases to carry out an explorative qualitative heuristic in-depth analysis.

RESULTS

These varied cases enabled us to describe diverse manifestations of practical wisdom; in addition, we were able to discern 10 different "interruptions" that triggered practical wisdom, and finally, we hypothesize that certain infrastructural figurations might facilitate the manifestation of practical wisdom.

CONCLUSIONS

We found that practical wisdom frequently emerged in unexpected and diverse guises in these clinical practices, although the "interruptions" that we discovered did not automatically trigger practical wisdom. We have investigated the figurations mentioned only to a limited degree. More empirical research is needed to make the philosophical concept of practical wisdom better manageable for clinical practices and to gain better understanding of the figurations that elicit or obstruct its manifestation.

Scientism, conflicts of interest, and the marginalization of ethics in medical education

AIM

This paper reports on the findings from 6 focus groups conducted with Australian medical students. The focus groups sought students' perspectives on how the influence of commercial interests on medical practice and education could be managed.

METHOD

We conducted 6 focus groups with medical students in New South Wales, Australia. Participants were recruited via student-run medical society and faculty e-mail lists. Forty-nine students from 6 medical schools in New South Wales participated. The research team reflected on the extent to which students uncritically appealed to science in the abstract as a management solution for conflicts of interest. Data analysis was largely inductive, looking for uses of scientific terminology, EBM, and appeals to "science" in the management of COI and applied theoretical analyses of scientism.

RESULTS

The students in our study suggested that science and evidence-based medicine, rather than ethics or professionalism, were the best tools to deal with undue influence and bias. This paper uses philosophy of science literature to critically examine these scientistic appeals to science and EBM as a means of managing the influence of pharmaceutical reps and commercial interests. We argue that a scientistic style of reasoning is reinforced through medical curricula and that students need to be made aware of the epistemological assumptions that underpin science, medicine, and EBM to address the ethical challenges associated with commercialised health care.

CONCLUSION

More work is needed to structure medical curricula to reflect the complexities of practice and realities of science. However, curricula change alone will not sufficiently address issues associated with commercial interests in medicine. For real change to occur, there needs to be a broader social and professional debate about the ways in which medicine and industry interact, and structural changes that restrict or mitigate commercial influences in educational, research, and policy settings.

The need for a rationalist turn in evidence-based medicine

When evidence-based medicine (EBM) became established, its dominant rhetoric was empiricist, in spite of rationalist elements in its practice. Exploring some of the key statements about EBM down the years, the paper examines the tensions between empiricism and rationalism and argues for a rationalist turn in EBM to help to develop the next generation of scholarship in the field.

Rethinking bias and truth in evidence-based health care

In modern philosophy, the concept of truth has been problematized from different angles, yet in evidence-based health care (EBHC), it continues to operate hidden and almost undisputed through the linked concept of "bias." To prevent unwarranted relativism and make better inferences in clinical practice, clinicians may benefit from a closer analysis of existing assumptions about truth, validity, and reality. In this paper, we give a brief overview of several important theories of truth, notably the ideal limit theorem (which assumes an ultimate and absolute truth towards which scientific inquiry progresses), the dominant way truth is conceptualized in the discourse and practice of EBHC. We draw on Belgian philosopher Isabelle Stengers' work to demonstrate that bias means one thing if one assumes a world of hard facts "out there," waiting to be collected. It means something different if one takes a critical view of the knowledge-power complex in research trials. Bias appears to have both an unproductive aspect and a productive aspect as argued by Stengers and others: Facts are not absolute but result from an interest, or interesse: a bias towards a certain line of questioning that cannot be eliminated. The duality that Stengers' view invokes draws attention to and challenges the assumptions underlying the ideal limit theory of truth in several ways. Most importantly, it casts doubt on the ideal limit theory as it applies to the single case scenario of the clinical encounter, the cornerstone of EBHC. To the extent that the goal of EBHC is to support inferencing in the clinical encounter, then the ideal limit as the sole concept of truth appears to be conceptually insufficient. We contend that EBHC could usefully incorporate a more pluralist understanding of truth and bias and provide an example how this would work out in a clinical scenario.

Task-related fMRI in hemiplegic cerebral palsy-A systematic review

RATIONALE

Functional magnetic resonance imaging (fMRI) is used widely to study reorganization after early brain injuries. Unilateral cerebral palsy (UCP) is an appealing model for studying brain plasticity by fMRI.

AIM

To summarize the results of task-related fMRI studies in UCP in order to get better understanding of the mechanism of neuroplasticity of the developing brain and its reorganization potential and better translation of this knowledge to clinical practice.

METHODS

A systematic search was conducted on the PubMed database by keywords: "cerebral palsy", "congenital hemiparesis", "unilateral", "Magnetic resonance imaging" , "fMRI", "reorganization", and "plasticity" The exclusion criteria were as follows: case reports; reviews; studies exploring non-UCP patients; and studies with results of rehabilitation.

RESULTS

We found 7 articles investigated sensory tasks; 9 studies-motor tasks; 12 studies-speech tasks. Ipsilesional reorganization is dominant in sensory tasks (in 74/77 patients), contralesional-in only 3/77. In motor tasks, bilateral activation is found in 64/83, only contralesional-in 11/83, and only ipsilesional-8/83. Speech perception is bilateral in 35/51, only or dominantly ipsilesional (left-sided) in 8/51, and dominantly contralesional (right-sided) in 8/51. Speech production is only or dominantly contralesional (right-sided) in 88/130, bilateral-26/130, and only or dominantly ipsilesional (left-sided)-in 16/130.

DISCUSSION

The sensory system is the most "rigid" to reorganization probably due to absence of ipsilateral (contralesional) primary somatosensory representation. The motor system is more "flexible" due to ipsilateral (contralesional) motor pathways. The speech perception and production show greater flexibility resulting in more bilateral or contralateral activation.

CONCLUSIONS

The models of reorganization are variable, depending on the development and function of each neural system and the extent and timing of the damage. The plasticity patterns may guide therapeutic intervention and prognostics, thus proving the fruitiness of the translational approach in neurosciences.

Responsibility Voids and Cooperation

Do responsibility voids exist? That is, are there situations in which the group is collectively morally responsible for some outcome although no member can be held individually morally responsible for it? To answer these questions, I draw a distinction between competitive and cooperative decision contexts based on the team-reasoning account of cooperation. Accordingly, I provide a reasoning-based analysis of cooperation, competition, moral responsibility, and, last, potential responsibility voids. I then argue that competitive decision contexts are free of responsibility voids. The conditions for the existence of responsibility voids in cooperative decision contexts depend on the type of uncertainty the group faces, either external or coordination uncertainty.

Clinical judgement in precision medicine

Precision medicine, which aims to individualize care based upon the unique combination of genetic, environmental, and lifestyle features in particular patients, will require an evolution in clinical decision making. Practitioners of precision medicine will need to utilize an expanded body of medical knowledge derived from a wide variety of sources. Clinical judgement in the case-based reasoning necessary for individualizing care will involve understanding and utilizing methodological approaches not commonly invoked in medicine, including mechanistic and qualitative research results. Instead of searching for an answer in the published literature, precision medicine demands clinical judgement that finds the reasons for clinical decisions within, not without, the patient.

Clinicians guide for cue-based transition to oral feeding in preterm infants: An easy-to-use clinical guide

RATIONALE, AIMS AND OBJECTIVES

This article aims to provide evidence to guide multidisciplinary clinical practitioners towards successful initiation and long-term maintenance of oral feeding in preterm infants, directed by the individual infant maturity.

METHOD

A comprehensive review of primary research, explorative work, existing guidelines, and evidence-based opinions regarding the transition to oral feeding in preterm infants was studied to compile this document.

RESULTS

Current clinical hospital practices are described and challenged and the principles of cue-based feeding are explored. "Traditional" feeding regimes use criteria, such as the infant's weight, gestational age and being free of illness, and even caregiver intuition to initiate or delay oral feeding. However, these criteria could compromise the infant and increase anxiety levels and frustration for parents and caregivers. Cue-based feeding, opposed to volume-driven feeding, lead to improved feeding success, including increased weight gain, shorter hospital stay, fewer adverse events, without increasing staff workload while simultaneously improving parents' skills regarding infant feeding. Although research is available on cue-based feeding, an easy-to-use clinical guide for practitioners could not be found. A cue-based infant feeding regime, for clinical decision making on providing opportunities to support feeding success in preterm infants, is provided in this article as a framework for clinical reasoning.

CONCLUSIONS

Cue-based feeding of preterm infants requires care providers who are trained in and sensitive to infant cues, to ensure optimal feeding success. An easy-to-use clinical guideline is presented for implementation by multidisciplinary team members. This evidence-based guideline aims to improve feeding outcomes for the newborn infant and to facilitate the tasks of nurses and caregivers.

Expected utility versus expected regret theory versions of decision curve analysis do generate different results when treatment effects are taken into account

RATIONALE, AIMS, AND OBJECTIVES

Decision curve analysis (DCA) is a widely used method for evaluating diagnostic tests and predictive models. It was developed based on expected utility theory (EUT) and has been reformulated using expected regret theory (ERG). Under certain circumstances, these 2 formulations yield different results. Here we describe these situations and explain the variation.

METHODS

We compare the derivations of the EUT- and ERG-based formulations of DCA for a typical medical decision problem: "treat none," "treat all," or "use model" to guide treatment. We illustrate the differences between the 2 formulations when applied to the following clinical question: at which probability of death we should refer a terminally ill patient to hospice?

RESULTS

Both DCA formulations yielded identical but mirrored results when treatment effects are ignored; they generated significantly different results otherwise. Treatment effect has a significant effect on the results derived by EUT DCA and less so on ERG DCA. The elicitation of specific values for disutilities affected the results even more significantly in the context of EUT DCA, whereas no such elicitation was required within the ERG framework.

CONCLUSION

EUT and ERG DCA generate different results when treatment effects are taken into account. The magnitude of the difference depends on the effect of treatment and the disutilities associated with disease and treatment effects. This is important to realize as the current practice guidelines are uniformly based on EUT; the same recommendations can significantly differ if they are derived based on ERG framework.

A survey of clinicians regarding respiratory physiotherapy intervention for intubated and mechanically ventilated patients with community-acquired pneumonia. What is current practice in Australian ICUs?

RATIONALE, AIMS, AND OBJECTIVES

Community-acquired pneumonia (CAP) is a common cause for intensive care unit (ICU) admission resulting in high morbidity and mortality. There is a paucity of evidence regarding respiratory physiotherapy for intubated and mechanically ventilated patients with CAP, and anecdotally clinical practice is variable in this cohort. The aims of this study were to identify the degree of variability in physiotherapy practice for intubated adult patients with CAP and to explore ICU physiotherapist perceptions of current practice for this cohort and factors that influence physiotherapy treatment mode, duration, and frequency.

METHOD

A survey was developed based on common aspects of assessment, clinical rationale, and intervention for intubated and mechanically ventilated patients. Senior ICU physiotherapists across 88 Australian public and private hospitals were recruited.

RESULTS

The response rate was 72%. Respondents (n = 75) stated their main rationale for providing a respiratory intervention were improved airway clearance (98%, n = 60/61), alveolar recruitment (74%, n = 45/61), and gas exchange (33%, n = 20/61). Respondents estimated that average intervention lasted between 16 and 30 minutes (70% of respondents, n = 41/59) and would be delivered once (44%) or twice (44%) daily. Results indicated large variability in reported practice; however, trends existed regarding positioning in alternate side-lying (81%, n = 52/64) or affected lung uppermost (83%, n = 53/64) and use of hyperinflation techniques (81%, 52/64). Decisions regarding duration were reported to be based on sputum volume (95%), viscosity (93%) and purulence (88%), cough effectiveness (95%), chest X-ray (87%), and auscultation (84%). Sixty percent reported that workload and staffing affected intervention duration and frequency. Intervention time was more likely increased when there was greater staffing (P = .03).

CONCLUSION

Respiratory physiotherapy treatment varies for intubated patients with CAP. Further research is required to determine what is considered best practice for this patient population.

Development of a cross-disciplinary continuous insulin infusion protocol for non-critically ill patients in a French university hospital

RATIONALE, AIMS AND OBJECTIVES

In non-critically ill patients, the use of an insulin syringe pump allows the management of temporary situations during which other therapies cannot be used (failure of subcutaneous injections, awaiting advice from the diabetes team, emergency situations, prolonged corticosteroid therapy, initiation of an artificial nutrition, need for a fasting status, etc.). To manage the risks related to this «never event», the use of a standard validated protocol for insulin administration and monitoring is an essential prerequisite. To this end, a multidisciplinary approach is recommended.

METHOD

With the support of our subcommission «Endocrinology-Diabetology», we proceeded with a «step-by-step process» to create such a standardized protocol: (1) review of all existing protocols in our hospital; (2) overview of the literature data concerning insulin infusion protocols developed by multidisciplinary teams in France and abroad; (3) development of a standardized protocol for non-intensive care unit patients, respecting the current recommendations and adapting it to the working habits of health teams; and (4) validation of the protocol

RESULTS

Two protocols based on the same structure but adapted to the health status of the patient have been developed. The protocols are divided in to three parts: (1) golden rules to make the use of the protocol appropriate and safe; (2) the algorithm (a double entry table) corresponding to a dynamic adaptation of insulin doses, clearly defining the target and the 'at risk situations'; and (3) practical aspects of the protocol: preparation of the syringe, treatment initiation and traceability. The protocols have been validated by the institution.

CONCLUSION

Our standardized insulin infusion protocol is simple, easy to implement, safe and is likely to be applicable in diverse care units. However, the efficiency, safety and the workability of our protocols have to be clinically evaluated.

Best Practices in Integrating Theory and Practice in Graduate Education in Public Health Promotion

Over the last several decades, consistent concerns have been raised about the quality of education and training provided to students in public health. In this article, we consider the implications of epidemiological transition-the decline of infectious diseases and rise of chronic diseases-for the types of education and training that would be most well suited for preparing students in health promotion to address the social and behavioral factors now associated with the leading causes of morbidity and mortality. As a result of this historic shift in disease etiology, the recommendation is to expand opportunities for applied experiential learning. Students need to become more adept at diagnosing the complex social, moral, and political dynamics that shape community priorities, perceptions of causes, and framing of health issues. The specific constellation of players, their history, relationships, and interpersonal dynamics are unique to each particular community setting, and hence, students need to become more sensitive to and proficient at picking up on the most significant influences and characteristics at work in the situation at hand. This type of "practical reasoning" stands in contrast to the perceived value of generalizable knowledge characteristic of models developed in the natural sciences. The ability to recognize and respond appropriately to the unique characteristics of a specific situation is best strengthened through extended practical experience.

The use of mobile smart devices and medical apps in the family practice setting

RATIONALE, AIMS AND OBJECTIVES

In this study smartphones/tablet PCs and medical application utilization by family physicians and factors concerning the acceptance of medical application in family practice setting have been studied.

METHODS

One hundred seventy-six participants voluntarily agreed to fill out a 27-item questionnaire. Data were analysed with descriptive statistics and eight items (acceptability of utilization of applications) revealed Cronbach's alpha of 0.965 and the factor analysis showed one factor explaining 80.6% of total variance.

RESULTS

The mean age of respondents was 35.7 [standard deviation (SD) = 8.12; min-max = 24-52], 79 were male (45.9%) and 88 female (51.2%), 56 (32.5%) were single and 113 (65.7%) married, and the mean experience duration as a physician was 11.1 years (SD = 11.1; min-max = 1-28). One hundred sixty-seven (97.1%) had a smartphone and/or tablet PC. Smartphone and/or tablet PC were used since 3.7 (SD = 2.17; min-max = 0-12) years. Sixty-one (35.5%) felt that smartphone and/or tablet PC are very important, 92 (53.5%) important, 2 (1.2%) unimportant and 12 (7%) were undecided about this. One hundred eleven (64.5%) participants had a medical application on the smartphone and 66 (38.4%) on the tablet PC. They used 1.7 (SD = 2.04; min-max = 0-10) medical applications for 1.45 (SD = 2.53; min-max = 0-25) times on average. Eighty respondents (66.7%) used a medical application for any medical problem.

CONCLUSIONS

Almost all family physicians used smartphone and/or tablet PC during daily practice, and the reason of use was commonly for communication and Internet purposes. Usage during working hours was limited, but medical apps were perceived mainly positively for receiving medical information via Internet. Looking at the medical apps' acceptability scale, participants were in agreement with the security, cost, contents' quality, ease of use, support, ease of finding, ease of accessing and motivation to use medical applications.

What are the primary influences on treatment decisions? How does this reflect on evidence-based practice? Indications from the discipline of speech and language therapy

RATIONALE, AIMS AND OBJECTIVES

Four pillars of evidence underpin evidence-based behavioural practice: research evidence, practice evidence, patient evidence and contextual evidence. However, it is unknown which of these pillars or other factors are used by clinicians such as speech and language therapists (SLTS) when making treatment choices. The aim of this study was to identify the factors underpinning SLTs' treatment decisions and contextualize findings in terms of evidence-based practice (EBP).

METHODS

Ethical approval was obtained for the electronic questionnaire-based study. A questionnaire was designed, piloted and then sent via gatekeepers to SLTs to ascertain agreement with a range of statements potentially underpinning treatment choices.

RESULTS

A total of 249 respondents completed the survey. The respondents defined themselves as dynamic and pragmatic practitioners with an appreciation for the four pillars of EBP. Using factor analysis, treatment decisions were found to rely primarily on practice evidence and pragmatic considerations. Qualifications, clinical experience and the patient group an SLT works with further influenced attitudes and treatment decisions. Those with additional qualifications and experience were identified as more autonomous, more scientific in their treatment choices and less influenced by patient preferences.

CONCLUSION

Factors influencing decision making did not clearly align with the four pillars of EBP, the principal influences being practice evidence and pragmatic constraints. The findings of this study have implications for understanding why specific treatment choices are made. Attempts to improve practice should focus on a range of evidence sources and take into account clinician's specific needs depending on career stage, post-qualification status and patient group factors of their practice.

Making reasonable decisions: a qualitative study of medical decision making in the care of patients with a clinically significant haemoglobin disorder

RATIONALE, AIMS AND OBJECTIVES

Therapies utilized in patients with clinically significant haemoglobin disorders appear to vary between clinicians and units. This study aimed to investigate the processes of evidence implementation and medical decision making in the care of such patients in NSW, Australia.

METHODS

Using semi-structured interviews, 11 haematologists discussed their medical decision-making processes with particular attention paid to the use of published evidence. Transcripts were thematically analysed by a single investigator on a line-by-line basis.

RESULTS

Decision making surrounding the care of patients with significant haemoglobin disorders varied and was deeply contextual. Three main determinants of clinical decision making were identified - factors relating to the patient and to their illness, factors specific to the clinician and the institution in which they were practising and factors related to the notion of evidence and to utility and role of evidence-based medicine in clinical practice.

CONCLUSIONS

Clinicians pay considerable attention to medical decision making and evidence incorporation and attempt to tailor these to particular patient contexts. However, the patient context is often inferred and when discordant with the clinician's own contexture can lead to discomfort with decision recommendations. Clinicians strive to improve comfort through the use of experience and trustworthy evidence.

Translating between social worlds of policy and everyday life: The development of a group-based method to support policymaking by exploring behavioural aspects of sustainable consumption

A large international literature on how lay citizens make sense of various aspects of science and technology has been generated by investigations which utilise small group methods. Within that literature, focus group and other group-based methods have come to co-exist, and to some extent, hybridise, with the use of small groups in citizen engagement initiatives. In this article, we report on how we drew upon these methodological developments in the design and operationalisation of a policymaking support tool (STAVE). This tool has been developed to gain insight, in a relatively speedy and cost-effective way, into practical details of the everyday lived experience of people's lives, as relating to the sustainability of corresponding practices. An important challenge we faced was how, in Kuhn's terms, to 'translate' between the forms of life corresponding to the world of policymaking and the world of everyday domestic life. We examine conceptual and methodological aspects of how the tool was designed and assembled, and then trialled in the context of active real-world collaborations with policymaking organisations. These trials were implemented in six European countries, where they were used to support work on live policy issues concerned with sustainable consumption.

Framing of scientific knowledge as a new category of health care research

RATIONALE

The new area of health system research requires a revision of the taxonomy of scientific knowledge that may facilitate a better understanding and representation of complex health phenomena in research discovery, corroboration and implementation.

METHOD

A position paper by an expert group following and iterative approach.

RESULTS

'Scientific evidence' should be differentiated from 'elicited knowledge' of experts and users, and this latter typology should be described beyond the traditional qualitative framework. Within this context 'framing of scientific knowledge' (FSK) is defined as a group of studies of prior expert knowledge specifically aimed at generating formal scientific frames. To be distinguished from other unstructured frames, FSK must be explicit, standardized, based on the available evidence, agreed by a group of experts and subdued to the principles of commensurability, transparency for corroboration and transferability that characterize scientific research. A preliminary typology of scientific framing studies is presented. This typology includes, among others, health declarations, position papers, expert-based clinical guides, conceptual maps, classifications, expert-driven health atlases and expert-driven studies of costs and burden of illness.

CONCLUSIONS

This grouping of expert-based studies constitutes a different kind of scientific knowledge and should be clearly differentiated from 'evidence' gathered from experimental and observational studies in health system research.

Children's strategic theory of mind

Human strategic interaction requires reasoning about other people's behavior and mental states, combined with an understanding of their incentives. However, the ontogenic development of strategic reasoning is not well understood: At what age do we show a capacity for sophisticated play in social interactions? Several lines of inquiry suggest an important role for recursive thinking (RT) and theory of mind (ToM), but these capacities leave out the strategic element. We posit a strategic theory of mind (SToM) integrating ToM and RT with reasoning about incentives of all players. We investigated SToM in 3- to 9-y-old children and adults in two games that represent prevalent aspects of social interaction. Children anticipate deceptive and competitive moves from the other player and play both games in a strategically sophisticated manner by 7 y of age. One game has a pure strategy Nash equilibrium: In this game, children achieve equilibrium play by the age of 7 y on the first move. In the other game, with a single mixed-strategy equilibrium, children's behavior moved toward the equilibrium with experience. These two results also correspond to two ways in which children's behavior resembles adult behavior in the same games. In both games, children's behavior becomes more strategically sophisticated with age on the first move. Beyond the age of 7 y, children begin to think about strategic interaction not myopically, but in a farsighted way, possibly with a view to cooperating and capitalizing on mutual gains in long-run relationships.

Investigating the degree of "stigma" associated with nuclear energy technologies: A cross-cultural examination of the case of fusion power

The extent to which nuclear energy technologies are, in some sense, "stigmatised" by historical environmental and military associations is of particular interest in contemporary debates about sustainable energy policy. Recent claims in the literature suggest that despite such stigmatisation, lay views on such technologies may be shifting towards a "reluctant acceptance," in the light of concerns about issues like anthropogenic climate change. In this paper, we report on research into learning and reasoning processes concerned with a largely unknown nuclear energy technology; namely fusion power. We focus on the role of the nuclear label, or "brand," in informing how lay citizens make sense of the nature of this technology. Our findings derive from a comparative analysis of data generated in Spain and Britain, using the same methodology.

Nurse leaders as stewards: the beginning of change

In understanding fully persons' moral predicaments, a core component of forming perceptual judgments, nurses may need to shift the epistemology of their practice from instrumental reasoning, or means-ends thinking, integrating a virtue-based practical reasoning. A bearing witness that achieves understanding of clients' moral qualities is attained through the articulation of nurses' self-identities within matrices, such as MacIntyre's theory of virtue ethics and standards and codes of ethics. Moreover, nurse leaders who exercise stewardship could apply the concept of communities of inquiry to structure learning conditions by which nurses may engage in experiential learning. This leadership enhanced by the nurse steward's phronetic knowledge, or practical wisdom, which guides understanding of how the clockwork of practical reasoning may evolve within such communities, is critical to nurses' shift in reasoning. Nonetheless, nurse leaders need empirical evidence to comprehend how stewards' accumulated moral insights may shape their character qualities, hence selection of values upon which to act in facilitating nurses' self-expression.
