Differential access to everyday technology and healthcare amongst safety net patients is associated with low technological and health literacies, respectively. These low rates of literacy produce a complex patient "knowledge gap" that influences the effectiveness of telehealth technologies. To understand this "knowledge gap", six focus groups (2 African-American and 4 Latino) were conducted with patients who received teleretinal screenings in U.S. urban safety-net settings. Findings indicate that patients' "knowledge gap" is primarily produced at three points: (1) when patients' preexisting personal barriers to care became exacerbated in the clinical setting; (2) through encounters with technology during screening; and (3) in doctor-patient follow-up. This "knowledge gap" can produce confusion and fear, potentially affecting patients' confidence in quality of care and limiting their disease management ability. In rethinking the digital divide to include the consequences of this knowledge gap faced by patients in the clinical setting, we suggest that patient education focus on both their disease and specific telehealth technologies deployed in care delivery.
Unintended adverse consequences of a clinical decision support system: two cases.
Stone, Erin G
2018-05-01
Many institutions have implemented clinical decision support systems (CDSSs). While CDSS research papers have focused on benefits of these systems, there is a smaller body of literature showing that CDSSs may also produce unintended adverse consequences (UACs). Detailed here are 2 cases of UACs resulting from a CDSS. Both of these cases were related to external systems that fed data into the CDSS. In the first case, lack of knowledge of data categorization in an external pharmacy system produced a UAC; in the second case, the change of a clinical laboratory instrument produced the UAC. CDSSs rely on data from many external systems. These systems are dynamic and may have changes in hardware, software, vendors, or processes. Such changes can affect the accuracy of CDSSs. These cases point to the need for the CDSS team to be familiar with these external systems. This team (manager and alert builders) should include members in specific clinical specialties with deep knowledge of these external systems.

This article takes lactose intolerance as a topic for exploring clashes of power, authority, and knowledge in clinical interactions and interpretations of laywomen. In clinics providing maternal and child care, staff and clients jointly produced authoritative knowledge, most often a version of biomedicine. The Euroamerican staff tended to give advice that was biologically appropriate for them but not for many of their patients, a process reflecting what we refer to as biocentrism. Resulting information given to pregnant and lactating women and diagnoses of children's growth patterns were inappropriate in some cases, with potentially serious legal and health implications. Clinic staff often unwittingly ignored the efforts of their clients to begin a discussion of discrepancies between their bodily knowledge and clinic advice. Some women created their own syntheses, which supported the ascendancy of biomedical knowledge but were not in the interests of their own health.

To identify the knowledge produced from the outcomes of the Nursing Outcomes Classification (NOC). A literature review using the integrative databases: Latin American and Caribbean Health Sciences (LILACS), US National Library of Medicine (PubMed), Cumulative Index to Nursing & Allied Health Literature (CINAHL) and Scopus Info Site (SCOPUS), during the months of August and September 2014. The review consisted of 21 articles that addressed different issues: Translation and Cultural adaptation (4.77%); Applicability in clinical practice (33.33%); and, Validation (63.90%). Analysis of these articles showed that the knowledge produced from the Nursing Outcomes Classification includes translation and cultural adaptation, evaluation of applicability and validation of its items. Considering the continuous evolution of this classification, periodic reviews should be carried out to identify the knowledge, use and effects of the NOC.

The purpose of this paper is to explore new perspectives about difficulties academicians may have communicating with clinicians, obtaining subjects, and gaining compliance for their research. Sackett et al1 defined evidence-based medicine (EBM) as an integration of best research evidence, clinical expertise, and patient values. However, Guyatt et al2 places clinical observation and experience last in the evidence hierarchy with the randomized controlled trial held as the standard for clinical intervention. The hierarchical discourse of medical knowledge produces opposition rather than collaboration between researcher, clinician, and patient. Foucault gave new perspectives describing how power circulates through individuals within organizational discourse.3 Drawing on literature and experience, this paper describes how the hierarchical model of power in the research community obstructs new areas of knowledge, and how clinicians create resistance. Alleviating perceptions of dominance and creating connections produces cohesion within medical communities. PMID:19018888

Summary China faces the immediate need of addressing the rapidly growing population with cardiovascular disease (CVD) events and the increasing numbers who are living with CVD. Despite progress in increasing access to services, China faces the dual challenge of addressing gaps in quality of care and producing more evidence to support clinical practice. In this article, we address opportunities to strengthen performance measurement, programs to improve quality of care and national capacity to produce high impact knowledge for clinical practice. Moreover, we propose recommendations, with implications for other conditions, for how China can immediately leverage its Hospital Quality Monitoring System and other existing national platforms to evaluate and improve performance, as well as generate new knowledge to inform clinical decisions and national policies.

Transforming practice into clinical scholarship.
Limoges, Jacqueline; Acorn, Sonia
2016-04-01
The aims of this paper were to explicate clinical scholarship as synonymous with the scholarship of application and to explore the evolution of scholarly practice to clinical scholarship. Boyer contributed an expanded view of scholarship that recognized various approaches to knowledge production beyond pure research (discovery) to include the scholarship of integration, application and teaching. There is growing interest in using Boyer's framework to advance knowledge production in nursing but the discussion of clinical scholarship in relation to Boyer's framework is sparse. Discussion paper. Literature from 1983-2015 and Boyer's framework. When clinical scholarship is viewed as a synonym for Boyer's scholarship of application, it can be aligned to this well established framework to support knowledge generated in clinical practice. For instance, applying the three criteria for scholarship (documentation, peer review and dissemination) can ensure that the knowledge produced is rigorous, available for critique and used by others to advance nursing practice and patient care. Understanding the differences between scholarly practice and clinical scholarship can promote the development of clinical scholarship. Supporting clinical leaders to identify issues confronting nursing practice can enable scholarly practice to be transformed into clinical scholarship. Expanding the understanding of clinical scholarship and linking it to Boyer's scholarship of application can assist nurses to generate knowledge that addresses clinical concerns. Further dialogue about how clinical scholarship can address the theory-practice gap and how publication of clinical scholarship could be expanded given the goals of clinical scholarship is warranted. © 2016 John Wiley & Sons Ltd.
Understanding the Knowledge Gap Experienced by U.S. Safety Net Patients in Teleretinal Screening.
George, Sheba M; Hayes, Erin Moran; Fish, Allison; Daskivich, Lauren Patty; Ogunyemi, Omolola I
2016-01-01
Safety-net patients' socioeconomic barriers interact with limited digital and health literacies to produce a "knowledge gap" that impacts the delivery of healthcare via telehealth technologies. Six focus groups (2 African- American and 4 Latino) were conducted with patients who received teleretinal screening in a U.S. urban safety-net setting. Focus groups were analyzed using a modified grounded theory methodology. Findings indicate that patients' knowledge gap is primarily produced at three points during the delivery of care: (1) exacerbation of patients' pre-existing personal barriers in the clinical setting; (2) encounters with technology during screening; and (3) lack of follow up after the visit. This knowledge gap produces confusion, potentially limiting patients' perceptions of care and their ability to manage their own care. It may be ameliorated through delivery of patient education focused on both disease pathology and specific role of telehealth technologies in disease management.

Since November 2009 carbapenemase-producing Klebsiella pneumoniae isolates have been detected in increasing numbers at the Clinical Centre University of Pécs. Molecular typing was performed for 102 clinical isolates originating from different time periods and various departments of the Clinical Centre. Pulsed-field gel electrophoresis revealed the predominance of a single clone (101/102), identified as sequence type ST15. PCR and sequencing showed the presence of blaCTX-M-15 and blaVIM-4 genes. The blaVIM-4 was located on a class 1 integron designated In238b. To our knowledge, this is the first description of a blaVIM-4 gene in the predominant CTX-M-15 extended spectrum β-lactamase-producing Hungarian Epidemic Clone/ST15. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.
The impact of impaired semantic knowledge on spontaneous iconic gesture production
Cocks, Naomi; Dipper, Lucy; Pritchard, Madeleine; Morgan, Gary
2013-01-01
Background Previous research has found that people with aphasia produce more spontaneous iconic gesture than control participants, especially during word-finding difficulties. There is some evidence that impaired semantic knowledge impacts on the diversity of gestural handshapes, as well as the frequency of gesture production. However, no previous research has explored how impaired semantic knowledge impacts on the frequency and type of iconic gestures produced during fluent speech compared with those produced during word-finding difficulties. Aims To explore the impact of impaired semantic knowledge on the frequency and type of iconic gestures produced during fluent speech and those produced during word-finding difficulties. Methods & Procedures A group of 29 participants with aphasia and 29 control participants were video recorded describing a cartoon they had just watched. All iconic gestures were tagged and coded as either “manner,” “path only,” “shape outline” or “other”. These gestures were then separated into either those occurring during fluent speech or those occurring during a word-finding difficulty. The relationships between semantic knowledge and gesture frequency and form were then investigated in the two different conditions. Outcomes & Results As expected, the participants with aphasia produced a higher frequency of iconic gestures than the control participants, but when the iconic gestures produced during word-finding difficulties were removed from the analysis, the frequency of iconic gesture was not significantly different between the groups. While there was not a significant relationship between the frequency of iconic gestures produced during fluent speech and semantic knowledge, there was a significant positive correlation between semantic knowledge and the proportion of word-finding difficulties that contained gesture. There was also a significant positive correlation between the speakers' semantic knowledge and the proportion of gestures that were produced during fluent speech that were classified as “manner”. Finally while not significant, there was a positive trend between semantic knowledge of objects and the production of “shape outline” gestures during word-finding difficulties for objects. Conclusions The results indicate that impaired semantic knowledge in aphasia impacts on both the iconic gestures produced during fluent speech and those produced during word-finding difficulties but in different ways. These results shed new light on the relationship between impaired language and iconic co-speech gesture production and also suggest that analysis of iconic gesture may be a useful addition to clinical assessment.

Producing Competent Doctors - The Art and Science of Teaching Clinical Skills.
Dhaliwal, Upreet; Supe, Avinash; Gupta, Piyush; Singh, Tejinder
2017-05-15
For a doctor to provide medical care with competence, he must not only have knowledge but must also be able to translate that knowledge into action. It is his competence in clinical skills that will enable him to practice safely and effectively in the real world. To ensure acquisition of clinical skills, medical teachers must adopt teaching methods that prioritise observation, practice, feedback; and more practice. We try to elucidate the meaning of clinical skills, the challenges inherent in clinical skills training in India, training models that have shown success in practice and can be adopted in the Indian context, and various techniques to enhance skill-training, including the giving of feedback, which is a critically important component of skills development.

Lack of knowledge and negative attitudes have been identified as barriers to participation in clinical trials by patients with cancer. We developed Preparatory Education About Clinical Trials (PRE-ACT), a theory-guided, Web-based, interactive computer program, to deliver tailored video educational content to patients in an effort to overcome barriers to considering clinical trials as a treatment option. A prospective, randomized clinical trial compared PRE-ACT with a control condition that provided general clinical trials information produced by the National Cancer Institute (NCI) in text format. One thousand two hundred fifty-five patients with cancer were randomly allocated before their initial visit with an oncologist to PRE-ACT (n = 623) or control (n = 632). PRE-ACT had three main components: assessment of clinical trials knowledge and attitudinal barriers, values assessment with clarification back to patients, and provision of a video library tailored to address each patient's barriers. Outcomes included knowledge and attitudes and preparation for decision making about clinical trials. Both PRE-ACT and control interventions improved knowledge and attitudes (all P < .001) compared with baseline. Patients randomly allocated to PRE-ACT showed a significantly greater increase in knowledge (P < .001) and a significantly greater decrease in attitudinal barriers (P < .001) than did their control (text-only) counterparts. Participants in both arms significantly increased their preparedness to consider clinical trials (P < .001), and there was a trend favoring the PRE-ACT group (P < .09). PRE-ACT was also associated with greater patient satisfaction than was NCI text alone. These data show that patient education before the first oncologist visit improves knowledge, attitudes, and preparation for decision making about clinical trials. Both text and tailored video were effective. The PRE-ACT interactive video program was more effective than NCI text in improving knowledge and reducing attitudinal barriers. © 2015 by American Society of Clinical Oncology.

Electroencephalography (EEG) remains an essential diagnostic tool for people with epilepsy (PWE). The International Federation of Clinical Neurophysiology produces new guidelines as an educational service for clinicians to address gaps in knowledge in clinical neurophysiology. The current guideline was prepared in response to gaps present in epilepsy-related neurophysiological assessment and is not intended to replace sound clinical judgement in the care of PWE. Furthermore, addressing specific pathophysiological conditions of the brain that produce epilepsy is of primary importance though is beyond the scope of this guideline. Instead, our goal is to summarize the scientific evidence for the utility of EEG when diagnosing and monitoring PWE. Copyright © 2018 International Federation of Clinical Neurophysiology.

To identify key principles for establishing a national clinical decision support (CDS) knowledge sharing framework. As part of an initiative by the US Office of the National Coordinator for Health IT (ONC) to establish a framework for national CDS knowledge sharing, key stakeholders were identified. Stakeholders' viewpoints were obtained through surveys and in-depth interviews, and findings and relevant insights were summarized. Based on these insights, key principles were formulated for establishing a national CDS knowledge sharing framework. Nineteen key stakeholders were recruited, including six executives from electronic health record system vendors, seven executives from knowledge content producers, three executives from healthcare provider organizations, and three additional experts in clinical informatics. Based on these stakeholders' insights, five key principles were identified for effectively sharing CDS knowledge nationally. These principles are (1) prioritize and support the creation and maintenance of a national CDS knowledge sharing framework; (2) facilitate the development of high-value content and tooling, preferably in an open-source manner; (3) accelerate the development or licensing of required, pragmatic standards; (4) acknowledge and address medicolegal liability concerns; and (5) establish a self-sustaining business model. Based on the principles identified, a roadmap for national CDS knowledge sharing was developed through the ONC's Advancing CDS initiative. The study findings may serve as a useful guide for ongoing activities by the ONC and others to establish a national framework for sharing CDS knowledge and improving clinical care.

The release of evidence-based practice (EBP) Web-based learning modules to the membership of the National Athletic Trainers' Association has provided athletic trainers (ATs) the opportunity to enhance their knowledge of the various EBP concepts. Whereas increasing the knowledge of EBP among ATs is important, assessing whether this newfound knowledge is being translated into clinical practice and didactic education is crucial. To explore the effectiveness of an educational intervention regarding EBP on the didactic instruction patterns of athletic training educators and the clinical practice behaviors of clinicians. Qualitative study. Individual telephone interviews. A total of 25 ATs (12 educators, 13 clinicians; experience as an AT = 16.00 ± 9.41 years) were interviewed. We conducted 1 individual telephone interview with each participant. After transcription, the data were analyzed and coded into common themes and categories. Triangulation of the data occurred via the use of multiple researchers and member checking to confirm the accuracy of the data. Participants perceived the EBP Web-based modules to produce numerous outcomes regarding education and clinical practice. These outcomes included perceived knowledge gain among participants, an increase in the importance and scope of EBP, a positive effect on educators' didactic instruction patterns and on instilling value and practice of EBP among students, and an enhanced ability among clinicians to implement EBP within clinical practice. However, some clinicians reported the Web-based modules had no current effect on clinical practice. Although the EBP Web-based modules were successful at enhancing knowledge among ATs, translation of knowledge into the classroom and clinical practice remains limited. Researchers should aim to identify effective strategies to help ATs implement EBP concepts into didactic education and clinical practice.

Objective To evaluate state-of-the-art unsupervised methods on the word sense disambiguation (WSD) task in the clinical domain. In particular, to compare graph-based approaches relying on a clinical knowledge base with bottom-up topic-modeling-based approaches. We investigate several enhancements to the topic-modeling techniques that use domain-specific knowledge sources. Materials and methods The graph-based methods use variations of PageRank and distance-based similarity metrics, operating over the Unified Medical Language System (UMLS). Topic-modeling methods use unlabeled data from the Multiparameter Intelligent Monitoring in Intensive Care (MIMIC II) database to derive models for each ambiguous word. We investigate the impact of using different linguistic features for topic models, including UMLS-based and syntactic features. We use a sense-tagged clinical dataset from the Mayo Clinic for evaluation. Results The topic-modeling methods achieve 66.9% accuracy on a subset of the Mayo Clinic's data, while the graph-based methods only reach the 40–50% range, with a most-frequent-sense baseline of 56.5%. Features derived from the UMLS semantic type and concept hierarchies do not produce a gain over bag-of-words features in the topic models, but identifying phrases from UMLS and using syntax does help. Discussion Although topic models outperform graph-based methods, semantic features derived from the UMLS prove too noisy to improve performance beyond bag-of-words. Conclusions Topic modeling for WSD provides superior results in the clinical domain; however, integration of knowledge remains to be effectively exploited. PMID:24441986

When implementing new technology into clinical practice, there will always be a need for large knowledge gain. The aim of this study was twofold, (I) audit the treatment planning and dose delivery of Flattening Filter Free (FFF) beam technology for Stereotactic Body Radiation Therapy (SBRT) of lung tumours across a range of treatment planning systems compared to the conventional Flatting Filter (FF) beams, (II) investigate how sharing knowledge between centres of different experience can improve plan quality. All vendor/treatment planning system (TPS) combinations investigated were able to produce acceptable treatment plans and the dose accuracy was clinically acceptable for all plans. By sharing knowledge between the different centres, the minor protocol violations (MPV) could be significantly reduced, from an average of 1.9 MPV per plan to 0.6 after such sharing of treatment planning knowledge. In particular, for the centres with less SBRT and/or volumetric- modulated arc therapy (VMAT) experience the MPV average per plan improved. All vendor/TPS combinations were also able to successfully deliver the FF and FFF SBRT VMAT plans. The plan quality and dose accuracy were found to be clinically acceptable.
Learning a Health Knowledge Graph from Electronic Medical Records.

2017-07-20
Demand for clinical decision support systems in medicine and self-diagnostic symptom checkers has substantially increased in recent years. Existing platforms rely on knowledge bases manually compiled through a labor-intensive process or automatically derived using simple pairwise statistics. This study explored an automated process to learn high quality knowledge bases linking diseases and symptoms directly from electronic medical records. Medical concepts were extracted from 273,174 de-identified patient records and maximum likelihood estimation of three probabilistic models was used to automatically construct knowledge graphs: logistic regression, naive Bayes classifier and a Bayesian network using noisy OR gates. A graph of disease-symptom relationships was elicited from the learned parameters and the constructed knowledge graphs were evaluated and validated, with permission, against Google's manually-constructed knowledge graph and against expert physician opinions. Our study shows that direct and automated construction of high quality health knowledge graphs from medical records using rudimentary concept extraction is feasible. The noisy OR model produces a high quality knowledge graph reaching precision of 0.85 for a recall of 0.6 in the clinical evaluation. Noisy OR significantly outperforms all tested models across evaluation frameworks (p < 0.01).

Background Throughout their medical education, learners face multiple transition periods associated with increased demands, producing stress and concern about the adequacy of their skills for their new role. Objective We evaluated the effectiveness of boot camps in improving clinical skills, knowledge, and confidence during transitions into postgraduate or discipline-specific residency programs. Methods Boot camps are in-training courses combining simulation-based practice with other educational methods to enhance learning and preparation for individuals entering new clinical roles. We performed a search of MEDLINE, CINAHL, PsycINFO, EMBASE, and ERIC using boot camp and comparable search terms. Inclusion criteria included studies that reported on medical education boot camps, involved learners entering new clinical roles in North American programs, and reported empirical data on the effectiveness of boot camps to improve clinical skills, knowledge, and/or confidence. A random effects model meta-analysis was performed to combined mean effect size differences (Cohen's d) across studies based on pretest/posttest or comparison group analyses. Results The search returned 1096 articles, 15 of which met all inclusion criteria. Combined effect size estimates showed learners who completed boot camp courses had significantly “large” improvements in clinical skills (d = 1.78; 95% CI 1.33–2.22; P < .001), knowledge (d = 2.08; 95% CI 1.20–2.96; P < .001), and confidence (d = 1.89; 95% CI 1.63–2.15; P < .001). Conclusions Boot camps were shown as an effective educational strategy to improve learners' clinical skills, knowledge, and confidence. Focus on pretest/posttest research designs limits the strength of these findings. PMID:26140112
Integration of basic sciences and clinical sciences in oral radiology education for dental students.
Baghdady, Mariam T; Carnahan, Heather; Lam, Ernest W N; Woods, Nicole N
2013-06-01
Educational research suggests that cognitive processing in diagnostic radiology requires a solid foundation in the basic sciences and knowledge of the radiological changes associated with disease. Although it is generally assumed that dental students must acquire both sets of knowledge, little is known about the most effective way to teach them. Currently, the basic and clinical sciences are taught separately. This study was conducted to compare the diagnostic accuracy of students when taught basic sciences segregated or integrated with clinical features. Predoctoral dental students (n=51) were taught four confusable intrabony abnormalities using basic science descriptions integrated with the radiographic features or taught segregated from the radiographic features. The students were tested with diagnostic images, and memory tests were performed immediately after learning and one week later. On immediate and delayed testing, participants in the integrated basic science group outperformed those from the segregated group. A main effect of learning condition was found to be significant (p<0.05). The results of this study support the critical role of integrating biomedical knowledge in diagnostic radiology and shows that teaching basic sciences integrated with clinical features produces higher diagnostic accuracy in novices than teaching basic sciences segregated from clinical features.

Around the world, teams of researchers continue to develop a wide range of systems to capture, store, and analyze data including treatment, patient outcomes, tumor registries, next-generation sequencing, single-nucleotide polymorphism, copy number, gene expression, drug chemistry, drug safety, and toxicity. Scientists mine, curate, and manually annotate growing mountains of data to produce high-quality databases, while clinical information is aggregated in distant systems. Databases are currently scattered, and relationships between variables coded in disparate datasets are frequently invisible. The challenge is to evolve oncology informatics from a "systems" orientation of standalone platforms and silos into an "integrated knowledge environments" that will connect "knowable" research data with patient clinical information. The aim of this article is to review progress toward an integrated knowledge environment to support modern oncology with a focus on supporting scientific discovery and improving cancer care.
Strategies for implementation of an effective pharmacogenomics program in pharmacy education.
Rao, U Subrahmanyeswara; Mayhew, Susan L; Rao, Prema S
2015-07-01
Sequencing of the human genome and the evidence correlating specific genetic variations to diseases have opened up the potential of genomics to more effective and less harmful interventions of human diseases. A wealth of pharmacogenomics knowledge is in place for the practice of precision medicine. However, this knowledge is not fully realized in clinical practice. One reason for this impasse is the lack of in-depth understanding of the potential of pharmacogenomics among the healthcare professionals. Pharmacists are the point-of-care providers and are expected to advise clinicians on matters relating to the implementation of pharmacogenomics in patient care. However, current pharmacogenomics instruction in pharmacy schools fails to produce pharmacists with the required knowledge or practical training in this discipline. In this perspective, we provide several strategies to overcome limitations faced by pharmacy schools. Once implemented, pharmacy schools will produce precision medicine-ready pharmacists.

The development of clinical reasoning and decision-making skills is often limited in medical school curricula. In reality, medical graduates acquire these skills during their first few years of residency. For many, this can be stressful as they may be working under limited supervision as a part of their rotations. Student-led Grand Rounds was developed to transfer both explicit and tacit knowledge to final year medical students. This pilot project was to apply the principles of knowledge management to allow students to be exposed to the reasoning and decision making of common clinical presentations. Student feedback through questionnaires was collated at the end of the program. Based on feedback and focus groups, modifications were made to produce a stable program in subsequent clinical rotations. Formal feedback was collated from all the 76 students who participated in the first year. This represented 100% of the cohort for this clinical school for that year. There was a 100% response rate as the feedback forms were given and collected at the end of the last session per block. The student responses were both in ratings defined in a feedback forms and in written comments. A total of 74 of the 76 students rated the program highly. They enjoyed the nonthreatening interactions. The remaining two students preferred more didactic teaching. This initiative allows an efficient transfer and utilization of knowledge. This could maximize the acquisition of practical knowledge by medical students as they finish their course in the transition to graduate medical practice.

The knowledge of principles and methods of Evidence Based Medicine (EBM) and the use of Clinical Practice Guidelines to inform clinical decisions are recognised as key instruments to improve the quality of care. In Italy the Parliament has revised the legal system that rules the responsibilities of health professionals and health care safety, prescribing health professionals to adhere to guidelines and good practice recommendations. The objective of the study was to evaluate guidelines and clinical pathways developed at local level and to assess knowledge and attitudes of healthcare workers toward EBM and guidelines. At the l'ASL 5 Liguria La Spezia we performed a census of all the documents registered as "guidelines" or "clinical pathways" at the Direzione Generale by the end of May 2016. We assessed their methodological quality by the "Recognition Card for Clinical Pathways Production and Revision Activity" prepared by the Ligurian Region. We conducted semi-structured interviews to assess attitudes and knowledge of healthcare workers. We found 17 clinical pathways, 41% contained organizational/management recommendations, and 59% contained mainly clinical recommendations. 41% was produced by assimilating already existing guidelines. 29% did not describe the method of production. Only one document linked directly each recommendation with scientific evidence. 10 healthcare workers out of 32 invited actually accepted to conduct the interview. Respondents showed a positive attitude toward the EBM and guidelines but a poor knowledge of the methodology of production and the instruments and principles for critical appraising of scientific literature. Nobody knew the GRADE approach. The most relevant barriers identified were: lack of time, poor knowledge of English and statistical methods, poor applicability of the international guidelines to local setting and real patients encountered in clinical practice. Despite the initiatives of the legislator toward civil responsibility and safety of care that should increase the use of guidelines, we found an overall poor knowledge of the concepts of EBM and method of guidelines production. Though the attitudes of responders to the interview were positive, barriers to use seemed to be predominant and considered more as obstacles than as a stimulus. In peripheral settings or in hospitals of medium/small size, clinical guidelines could remain confined to a merely juridical role, with weak impact on professional practice.
Increasing the automation of a 2D-3D registration system.
Varnavas, Andreas; Carrell, Tom; Penney, Graeme

Routine clinical use of 2D-3D registration algorithms for Image Guided Surgery remains limited. A key aspect for routine clinical use of this technology is its degree of automation, i.e., the amount of necessary knowledgeable interaction between the clinicians and the registration system. Current image-based registration approaches usually require knowledgeable manual interaction during two stages: for initial pose estimation and for verification of produced results. We propose four novel techniques, particularly suited to vertebra-based registration systems, which can significantly automate both of the above stages. Two of these techniques are based upon the intraoperative "insertion" of a virtual fiducial marker into the preoperative data. The remaining two techniques use the final registration similarity value between multiple CT vertebrae and a single fluoroscopy vertebra. The proposed methods were evaluated with data from 31 operations (31 CT scans, 419 fluoroscopy images). Results show these methods can remove the need for manual vertebra identification during initial pose estimation, and were also very effective for result verification, producing a combined true positive rate of 100% and false positive rate equal to zero. This large decrease in required knowledgeable interaction is an important contribution aiming to enable more widespread use of 2D-3D registration technology.
Attention to local health burden and the global disparity of health research.

Most studies on global health inequality consider unequal health care and socio-economic conditions but neglect inequality in the production of health knowledge relevant to addressing disease burden. We demonstrate this inequality and identify likely causes. Using disability-adjusted life years (DALYs) for 111 prominent medical conditions, assessed globally and nationally by the World Health Organization, we linked DALYs with MEDLINE articles for each condition to assess the influence of DALY-based global disease burden, compared to the global market for treatment, on the production of relevant MEDLINE articles, systematic reviews, clinical trials and research using animal models vs. humans. We then explored how DALYs, wealth, and the production of research within countries correlate with this global pattern. We show that global DALYs for each condition had a small, significant negative relationship with the production of each type of MEDLINE articles for that condition. Local processes of health research appear to be behind this. Clinical trials and animal studies but not systematic reviews produced within countries were strongly guided by local DALYs. More and less developed countries had very different disease profiles and rich countries publish much more than poor countries. Accordingly, conditions common to developed countries garnered more clinical research than those common to less developed countries. Many of the health needs in less developed countries do not attract attention among developed country researchers who produce the vast majority of global health knowledge--including clinical trials--in response to their own local needs. This raises concern about the amount of knowledge relevant to poor populations deficient in their own research infrastructure. We recommend measures to address this critical dimension of global health inequality.

Understanding the prevalence of cattle producers' beliefs regarding disease reporting can help officials improve surveillance programs with passive data collection. A cross-sectional survey was conducted in Texas in 2008 and 2009 to determine beliefs about reporting cattle with clinical signs consistent with foot-and-mouth disease (FMD) either prior to (scenario 1) or during an on-going outbreak of FMD (scenario 2). Two questionnaires were developed and distributed to Texas cow-calf producers in order to evaluate their behavioral, control, and normative beliefs related to disease reporting. The context for each behavior was provided through the use of scenarios, and belief strength was measured using a 7-point Likert-like scale. Beliefs were compared across scenarios and demographic categories, and the effect of scenario on belief examined using ordinal logistic regression. Respondents agreed that reporting clinically suspect cases would have positive economic and emotional consequences; however, when an outbreak was known to be present, producers were less likely to agree with many of the positive outcomes of reporting. Important barriers to disease reporting indicated by producers included a lack of knowledge related to clinical signs of highly contagious cattle diseases and which cattle are at risk of contracting FMD. In general, beliefs about barriers to reporting did not differ based on scenario. Veterinarians and regulatory authorities were the groups perceived to most strongly expect disease reporting, regardless of the scenario. Risk education for producers related to clinical signs of reportable livestock diseases, post-reporting procedures, and an understanding of FMD introduction and spread may improve the reporting of cattle with clinical signs consistent with FMD.

Development of a residency program in radiation oncology physics: an inverse planning approach.
Khan, Rao F H; Dunscombe, Peter B
2016-03-08
Over the last two decades, there has been a concerted effort in North America to organize medical physicists' clinical training programs along more structured and formal lines. This effort has been prompted by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP) which has now accredited about 90 residency programs. Initially the accreditation focused on standardized and higher quality clinical physics training; the development of rounded professionals who can function at a high level in a multidisciplinary environment was recognized as a priority of a radiation oncology physics residency only lately. In this report, we identify and discuss the implementation of, and the essential components of, a radiation oncology physics residency designed to produce knowledgeable and effective clinical physicists for today's safety-conscious and collaborative work environment. Our approach is that of inverse planning, by now familiar to all radiation oncology physicists, in which objectives and constraints are identified prior to the design of the program. Our inverse planning objectives not only include those associated with traditional residencies (i.e., clinical physics knowledge and critical clinical skills), but also encompass those other attributes essential for success in a modern radiation therapy clinic. These attributes include formal training in management skills and leadership, teaching and communication skills, and knowledge of error management techniques and patient safety. The constraints in our optimization exercise are associated with the limited duration of a residency and the training resources available. Without compromising the knowledge and skills needed for clinical tasks, we have successfully applied the model to the University of Calgary's two-year residency program. The program requires 3840 hours of overall commitment from the trainee, of which 7%-10% is spent in obtaining formal training in nontechnical "soft skills".

Background Knowledge on the clinical features of infections caused by Escherichia coli producing plasmid-mediated AmpC β-lactamase is limited. Of the several groups of plasmid-mediated AmpC β-lactamase, CMY-type β-lactamase is the most common in the United States. Methods We prospectively identified E. coli producing CMY-type β-lactamase and collected clinical data over a seven-month period. A retrospective cohort study was performed to identify features associated with these cases, using cases due to extended-spectrum β-lactamase (ESBL)-producing E. coli as controls. Pulsed-field gel electrophoresis (PFGE), plasmid analysis and phylogenetic typing were performed. Results Twenty-two cases with CMY-producing E. coli and 25 cases with ESBL-producing E. coli were identified. The demographics of the patients were similar between the CMY and ESBL cohorts. CMY cases were significantly more likely to represent symptomatic infection compared with ESBL cases (P=0.028). The CMY-type β-lactamase was identified as CMY-2 or its variants. Ninety-four percent of the CMY-producing isolates belonged to E. coli phylogenetic groups B2 and D, which are associated with virulence. Many of them shared similar plasmid profiles, whereas the PFGE profiles were diverse. Co-resistance to non-β-lactam antimicrobials was common. Conclusion In Pittsburgh, CMY-producing E. coli is almost as common as ESBL-producing E. coli and causes symptomatic infection in the majority of cases. PMID:19187027

Background Translational medicine requires the integration of knowledge using heterogeneous data from health care to the life sciences. Here, we describe a collaborative effort to produce a prototype Translational Medicine Knowledge Base (TMKB) capable of answering questions relating to clinical practice and pharmaceutical drug discovery. Results We developed the Translational Medicine Ontology (TMO) as a unifying ontology to integrate chemical, genomic and proteomic data with disease, treatment, and electronic health records. We demonstrate the use of Semantic Web technologies in the integration of patient and biomedical data, and reveal how such a knowledge base can aid physicians in providing tailored patient care and facilitate the recruitment of patients into active clinical trials. Thus, patients, physicians and researchers may explore the knowledge base to better understand therapeutic options, efficacy, and mechanisms of action. Conclusions This work takes an important step in using Semantic Web technologies to facilitate integration of relevant, distributed, external sources and progress towards a computational platform to support personalized medicine.

Guideline-based clinical decision support systems (CDSSs) can be effective in increasing physician compliance with recommendations. However, the ever growing pace at which medical knowledge is produced requires that clinical practice guidelines (CPGs) be updated regularly. It is therefore mandatory that CDSSs be revised accordingly. The French Association for Urology publishes CPGs on bladder cancer management every 2 years. We studied the impact of the 2004 revision of these guidelines, with respect to the 2002 version with a CDSS, UroDoc. We proposed a typology of knowledge base modifications resulting from the update of CPGs making the difference between practice, clinical conditions and recommendations refinement as opposed to new practice and new recommendations. The number of formalized recommendations increased from 577 in 2002 to 1,081 in 2004. We evaluated the two versions of UroDoc on a randomized sample of patient records. A single new practice that modifies a decision taken in 49% of all recorded decisions leads to a fall from 67% to 46% of the compliance rate of decisions.

The translation of biomedical research from basic knowledge to application has been a priority at the National Institute of Health (NIH) for many years. Tracking the progress of scientific research and knowledge through the translational process is difficult due to variation in the definition of translational research as well as the identification of benchmarks for the spread and application of biomedical research; quantitatively tracking this process is even more difficult. Using a simple and reproducible method to assess whether publications are translational, we examined NIH R01 behavioral and social science research (BSSR) awards funded between 2008 and 2014 to determine whether there are differences in the percent of translational research publications produced by basic and applied research awards. We also assessed the percent of translational research publications produced by the Clinical and Translational Science Awards (CTSA) program to evaluate whether targeted translational research awards result in increased translational research. We found that 3.9% of publications produced by basic research awards were translational; that the percent of translational research publications produced by applied research awards is approximately double that of basic research awards (7.4%); and that targeted translational research awards from the CTSA program produced the highest percentage of translational research publications (13.4%). In addition, we assessed differences in time to first publication, time to first citation, and publication quality by award type (basic vs. applied), and whether an award (or publication) is translational.

The ECRAN (European Communication on Research Awareness Needs) project was initiated in 2012, with support from the European Commission, to improve public knowledge about the importance of independent, multinational, clinical trials in Europe. Participants in the ECRAN consortium included clinicians and methodologists directly involved in clinical trials; researchers working in partnership with the public and patients; representatives of patients; and experts in science communication. We searched for, and evaluated, relevant existing materials and developed additional materials and tools, making them freely available under a Creative Commons licence. The principal communication materials developed were: 1. A website ( http://ecranproject.eu ) in six languages, including a Media centre section to help journalists to disseminate information about the ECRAN project 2. An animated film about clinical trials, dubbed in the 23 official languages of the European Community, and an interactive tutorial 3. An inventory of resources, available in 23 languages, searchable by topic, author, and media type 4. Two educational games for young people, developed in six languages 5. Testing Treatments interactive in a dozen languages, including five official European Community languages 6. An interactive tutorial slide presentation testing viewers' knowledge about clinical trials Over a 2-year project, our multidisciplinary and multinational consortium was able to produce, and make freely available in many languages, new materials to promote public knowledge about the importance of independent and international clinical trials. Sustained funding for the ECRAN information platform could help to promote successful recruitment to independent clinical trials supported through the European Clinical Research Infrastructure Network.
The effects of body position on distortion-product otoacoustic emission testing.
Driscoll, Carlie; Kei, Joseph; Shyu, Jenny; Fukai, Natasha
2004-09-01
Otoacoustic emissions are frequently acquired from patients in a variety of body positions aside from the standard, seated orientation. Yet little knowledge is available regarding whether these deviations will produce nonpathological changes to the clinical results obtained. The present study aimed to describe the effects of body position on the distortion-product otoacoustic emissions of 60 normal-hearing adults. With particular attention given to common clinical practice, the Otodynamics ILO292, and the measurement parameters of amplitude, signal-to-noise ratio, and noise were utilized. Significant position-related effects and interactions were revealed for all parameters. Specifically, stronger emissions in the mid frequencies and higher noise levels at the extreme low and high frequencies were produced by testing subjects while lying on their side compared with the seated position. Further analysis of body position effects on emissions is warranted, in order to determine the need for clinical application of position-dependent normative data.

Experience with simulated patients supports undergraduate learning of medical consultation skills. Adaptive simulations are being introduced into this environment. The authors investigate whether it can underpin valid and reliable assessment by conducting a generalizability analysis using IT data analytics from the interaction of medical students (in psychiatry) with adaptive simulations to explore the feasibility of adaptive simulations for supporting automated learning and assessment. The generalizability (G) study was focused on two clinically relevant variables: clinical decision points and communication skills. While the G study on the communication skills score yielded low levels of true score variance, the results produced by the decision points, indicating clinical decision-making and confirming user knowledge of the process of the Calgary-Cambridge model of consultation, produced reliability levels similar to what might be expected with rater-based scoring. The findings indicate that adaptive simulations have potential as a teaching and assessment tool for medical consultations.
Current knowledge about the hydrophilic and nanostructured SLActive surface
Wennerberg, Ann; Galli, Silvia; Albrektsson, Tomas
2011-01-01
This review summarizes the present documentation for the SLActive surface, a hydrophilic and nanostructured surface produced by Straumann Company in Switzerland, and covers the results from 15 in vitro, 17 in vivo, and 16 clinical studies. The SLActive surface is a development of the large grit-blasted and acid-etched SLA surface, and is further processed to a high degree of hydrophilicity. In general, the in vitro and in vivo studies of the SLActive surface demonstrate a stronger cell and bone tissue response than for the predecessor, the SLA surface, produced by the same company. However, in most studies, this difference disappears after 6–8 weeks. In the clinical studies, a stronger bone response was reported for the SLActive surface during the early healing phase when compared with the SLA surface. However, the later biological response was quite similar for the two surfaces and both demonstrated very good clinical results. PMID:23674916
AIM: a personal view of where I have been and where we might be going.
Rector, A
2001-08-01
My own career in medical informatics and AI in medicine has oscillated between concerns with medical records and concerns with knowledge representation with decision support as a pivotal integrating issue. It has focused on using AI to organise information and reduce 'muddle' and improve the user interfaces to produce 'useful and usable systems' to help doctors with a 'humanly impossible task'. Increasingly knowledge representation and ontologies have become the fulcrum for orchestrating re-use of information and integration of systems. Encouragingly, the dilemma between computational tractability and expressiveness is lessening, and ontologies and description logics are joining the mainstream both in AI in Medicine and in Intelligent Information Management generally. It has been shown possible to scale up ontologies to meet medical needs, and increasingly ontologies are playing a key role in meeting the requirements to scale up the complexity of clinical systems to meet the ever increasing demands brought about by new emphasis on reduction of errors, clinical accountability, and the explosion of knowledge on the Web.

Integrated knowledge translation (IKT) interventions may be one solution to improving the uptake of clinical guidelines. IKT research initiatives are particularly relevant for breast cancer research and initiatives targeting the implementation of clinical guidelines and guideline implementation initiatives, where collaboration with an interdisciplinary team of practitioners, patients, caregivers, and policy makers is needed for producing optimum patient outcomes. The objective of this paper was to describe the process of developing an IKT strategy that could be used by guideline developers to improve the uptake of their new clinical practice guidelines on breast cancer screening. An interprofessional group of students as well as two faculty members met six times over three days at the KT Canada Summer Institute in 2011. The team used all of the phases of the action cycle in the Knowledge to Action Framework as an organizing framework. While the entire framework was used, the step involving assessing barriers to knowledge use was judged to be particularly relevant in anticipating implementation problems and being able to inform the specific KT interventions that would be appropriate to mitigate these challenges and to accomplish goals and outcomes. This activity also underscored the importance of group process and teamwork in IKT. We propose that an a priori assessment of barriers to knowledge use (i.e., level and corresponding barriers), along with the other phases of the Knowledge to Action Framework, is a strategic approach for KT strategy development, implementation, and evaluation planning and could be used in the future planning of KT strategies.
Cognitive task analysis for instruction in single-injection ultrasound guided-regional anesthesia
NASA Astrophysics Data System (ADS)
Gucev, Gligor V.
Cognitive task analysis (CTA) is methodology for eliciting knowledge from subject matter experts. CTA has been used to capture the cognitive processes, decision-making, and judgments that underlie expert behaviors. A review of the literature revealed that CTA has not yet been used to capture the knowledge required to perform ultrasound guided regional anesthesia (UGRA). The purpose of this study was to utilize CTA to extract knowledge from UGRA experts and to determine whether instruction based on CTA of UGRA will produce results superior to the results of traditional training. This study adds to the knowledge base of CTA in being the first one to effectively capture the expert knowledge of UGRA. The derived protocol was used in a randomized, double blinded experiment involving UGRA instruction to 39 novice learners. The results of this study strongly support the hypothesis that CTA-based instruction in UGRA is more effective than conventional clinical instruction, as measured by conceptual pre- and post-tests, performance of a simulated UGRA procedure, and time necessary for the task performance. This study adds to the number of studies that have proven the superiority of CTA-informed instruction. Finally, it produced several validated instruments that can be used in instructing and evaluating UGRA.

Optical coherence tomography (OCT) has enabled "virtual biopsy" of the living human retina, revolutionizing both basic retina research and clinical practice over the past 25 years. For most of those years, in parallel, adaptive optics (AO) has been used to improve the transverse resolution of ophthalmoscopes to foster in vivo study of the retina at the microscopic level. Here, we review work done over the last 15 years to combine the microscopic transverse resolution of AO with the microscopic axial resolution of OCT, building AO-OCT systems with the highest three-dimensional resolution of any existing retinal imaging modality. We surveyed the literature to identify the most influential antecedent work, important milestones in the development of AO-OCT technology, its applications that have yielded new knowledge, research areas into which it may productively expand, and nascent applications that have the potential to grow. Initial efforts focused on demonstrating three-dimensional resolution. Since then, many improvements have been made in resolution and speed, as well as other enhancements of acquisition and postprocessing techniques. Progress on these fronts has produced numerous discoveries about the anatomy, function, and optical properties of the retina. Adaptive optics OCT continues to evolve technically and to contribute to our basic and clinical knowledge of the retina. Due to its capacity to reveal cellular and microscopic detail invisible to clinical OCT systems, it is an ideal companion to those instruments and has the demonstrable potential to produce images that can guide the interpretation of clinical findings.

Transfusion of red blood cells (RBCs) is a standard and indispensable therapy in current clinical practice. In vitro production of RBCs offers a potential means to overcome a shortage of transfusable RBCs in some clinical situations and also to provide a source of cells free from possible infection or contamination by microorganisms. Thus, in vitro production of RBCs may become a standard procedure in the future. We previously reported the successful establishment of immortalized mouse erythroid progenitor cell lines that were able to produce mature RBCs very efficiently. Here, we have developed a reliable protocol for establishing immortalized human erythroid progenitor cell lines that are able to produce enucleated RBCs. These immortalized cell lines produce functional hemoglobin and express erythroid-specific markers, and these markers are upregulated following induction of differentiation in vitro. Most importantly, these immortalized cell lines all produce enucleated RBCs after induction of differentiation in vitro, although the efficiency of producing enucleated RBCs remains to be improved further. To the best of our knowledge, this is the first demonstration of the feasibility of using immortalized human erythroid progenitor cell lines as an ex vivo source for production of enucleated RBCs.

Knowledge translation (KT) activities can reduce the gap between "what is known" and "what is done". Several factors hinder or facilitate KT activities including individual characteristics and organizational attributes; we will focus on individual healthcare professional modifiable characteristics. The purpose of this scoping review is to summarize knowledge on KT competencies for knowledge users, knowledge brokers, and knowledge producers/researchers to support evidence-based practice (EBP) and inform policy and research in health. Our objectives are to explore the relevant theoretical and empirical literature; map the publications for key themes and research gaps of KT competencies, and interventions for enhancing KT competencies; summarize and disseminate findings; produce an action plan and research agenda; and develop self-assessment tools (the KT Pathways) for professional development for our three target audiences. The scoping review method will guide our study by following six stages: formulating the research question; identifying relevant studies; selecting the literature; charting the data; collating, summarizing, and reporting the results; and developing a KT plan and consulting stakeholders involved in the fields of KT, EBP, evidence-informed policy-making, and/or research. We will include empirical and theoretical/conceptual peer-reviewed and grey literature in health that examine knowledge user, knowledge broker and knowledge producer KT competencies. Publications written in the English language and published after 2003 only will be considered. Our multidisciplinary research team will collaborate using technology (i.e., WebEx for discussions and a Web 2.0 website for storing documents). Our KT plan consists of an Advisory Group and dissemination plan of the findings. We expect the identified KT competencies to contribute to the KT science by providing positive outcomes in practice, policy, education, and future research. Incorporation of the core KT competencies may enhance safety, effectiveness of clinical care, and quality of health outcomes; contribute to and facilitate collaboration among practitioners, knowledge users, knowledge brokers, researchers, employers, and educators; improve education of healthcare professionals and inform policy-making process; benefit practitioners by guiding their KT professional development to become effective at moving evidence into practice and policy; guide suitable interventions and strategies to enhance KT activities in the health sector; and direct future research.

Objective Cancer can involve gene dysregulation via multiple mechanisms, so no single level of genomic data fully elucidates tumor behavior due to the presence of numerous genomic variations within or between levels in a biological system. We have previously proposed a graph-based integration approach that combines multi-omics data including copy number alteration, methylation, miRNA, and gene expression data for predicting clinical outcome in cancer. However, genomic features likely interact with other genomic features in complex signaling or regulatory networks, since cancer is caused by alterations in pathways or complete processes. Methods Here we propose a new graph-based framework for integrating multi-omics data and genomic knowledge to improve power in predicting clinical outcomes and elucidate interplay between different levels. To highlight the validity of our proposed framework, we used an ovarian cancer dataset from The Cancer Genome Atlas for predicting stage, grade, and survival outcomes. Results Integrating multi-omics data with genomic knowledge to construct pre-defined features resulted in higher performance in clinical outcome prediction and higher stability. For the grade outcome, the model with gene expression data produced an area under the receiver operating characteristic curve (AUC) of 0.7866. However, models of the integration with pathway, Gene Ontology, chromosomal gene set, and motif gene set consistently outperformed the model with genomic data only, attaining AUCs of 0.7873, 0.8433, 0.8254, and 0.8179, respectively. Conclusions Integrating multi-omics data and genomic knowledge to improve understanding of molecular pathogenesis and underlying biology in cancer should improve diagnostic and prognostic indicators and the effectiveness of therapies.

Pseudomonas putida is an uncommon opportunistic pathogen, usually susceptible to antimicrobial agents. Data concerning resistance to antimicrobial agents in clinical P. putida isolates are limited. To the best of our knowledge we report for the first time the isolation of NDM-1-producing multidrug-resistant P. putida from a case of acute gastroenteritis. The isolate showed resistance to a wide range of antimicrobials, including fluoroquinolones, third-generation cephalosporins and carbapenems. The isolate also exhibited multiple mutations in the quinolone resistance determining region and showed the presence of qepA, bla TEM , bla OXA1 and bla OXA7 genes. The present study highlights the importance of looking for the relatively rare aetiological agents in clinical samples that do not yield common pathogens.

Medical therapeutics: from induction to scientific evolution.
Nunes, José Pedro Lopes
2013-01-01
The field of medical therapeutics may be characterized as having suffered major scientific evolution in the last decades. The publication of landmark studies has been important enough to produce shifts in patient care. However, the scientific evolution in this field does not necessarily imply a progressively greater degree of certitude. In fact, it is not uncommon for new knowledge, when reflected in clinical practice, to weaken previous knowledge. In medical therapeutics, strict inductive reasoning implies the existence of empirical intervention data, typically clinical trial data. In many instances, however, such data does not exist-leaving room for a mixture of inductive and "pseudo-deductive" reasoning. It is often necessary to establish treatment on the basis of incomplete and inconclusive information, more so when the clinical situation is grave, but when no valid information exists, no treatment may be an option. In many instances, the rule "I wish not to impose on others" has superseded the concept "Do not impose on others what you yourself do not desire."
The establishment of the Australian and New Zealand Neonatal Network.
Donoghue, Deborah A; Henderson-Smart, David J
2009-01-01
The Australian and New Zealand Neonatal Network was established in 1994 to monitor high-risk newborns admitted for care. Uniquely, all units in both countries have participated since inception, making it integral to the care of babies. The network's objectives include auditing care, publishing aggregated results annually, providing feedback to units, monitoring technologies and developing clinical indicators. Networking provides a forum for clinicians and a consortium of knowledge and advice. It facilitates collaborative research and clinical groups, producing projects from observational studies to randomised controlled trials. Members take a major role in reviewing the evidence for care and ensuring its effective use in clinical practice.
Basic physics of laser interaction with vital tissue.
Wigdor, Harvey
2008-09-01
It is essential for any practitioner who uses lasers in their clinical practice to understand the basic physics of lasers. It is this knowledge that allows for an educated assessment of the clinical outcomes that lasers produce in our patients. It is also this understanding that provides a scientific basis for the visual feedback the clinician uses to vary parameters as needed to get the desired clinical results. It is the intent of this paper to discuss the very basic reasons why lasers affect tissues the way they do, and to synthesize the plethora of information dental practitioners are seeing regularly in dental journals.

Knowledge of the parameters of drug development can greatly aid academic scientists hoping to partner with pharmaceutical companies. Here, we discuss the three major pillars of drug development-pharmacodynamics, pharmacokinetics, and toxicity studies-which, in addition to pre-clinical efficacy, are critical for partnering with Big Pharma to produce novel therapeutics.

Development of a residency program in radiation oncology physics: an inverse planning approach
Dunscombe, Peter B.
2016-01-01
Over the last two decades, there has been a concerted effort in North America to organize medical physicists’ clinical training programs along more structured and formal lines. This effort has been prompted by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP) which has now accredited about 90 residency programs. Initially the accreditation focused on standardized and higher quality clinical physics training; the development of rounded professionals who can function at a high level in a multidisciplinary environment was recognized as a priority of a radiation oncology physics residency only lately. In this report, we identify and discuss the implementation of, and the essential components of, a radiation oncology physics residency designed to produce knowledgeable and effective clinical physicists for today's safety‐conscious and collaborative work environment. Our approach is that of inverse planning, by now familiar to all radiation oncology physicists, in which objectives and constraints are identified prior to the design of the program. Our inverse planning objectives not only include those associated with traditional residencies (i.e., clinical physics knowledge and critical clinical skills), but also encompass those other attributes essential for success in a modern radiation therapy clinic. These attributes include formal training in management skills and leadership, teaching and communication skills, and knowledge of error management techniques and patient safety. The constraints in our optimization exercise are associated with the limited duration of a residency and the training resources available. Without compromising the knowledge and skills needed for clinical tasks, we have successfully applied the model to the University of Calgary's two‐year residency program. The program requires 3840 hours of overall commitment from the trainee, of which 7%–10% is spent in obtaining formal training in nontechnical “soft skills”.

Background The purpose of this study was to identify recommended practices for computerized clinical decision support (CDS) development and implementation and for knowledge management (KM) processes in ambulatory clinics and community hospitals using commercial or locally developed systems in the U.S. Methods Guided by the Multiple Perspectives Framework, the authors conducted ethnographic field studies at two community hospitals and five ambulatory clinic organizations across the U.S. Using a Rapid Assessment Process, a multidisciplinary research team: gathered preliminary assessment data; conducted on-site interviews, observations, and field surveys; analyzed data using both template and grounded methods; and developed universal themes. A panel of experts produced recommended practices. Results The team identified ten themes related to CDS and KM. These include: 1) workflow; 2) knowledge management; 3) data as a foundation for CDS; 4) user computer interaction; 5) measurement and metrics; 6) governance; 7) translation for collaboration; 8) the meaning of CDS; 9) roles of special, essential people; and 10) communication, training, and support. Experts developed recommendations about each theme. The original Multiple Perspectives framework was modified to make explicit a new theoretical construct, that of Translational Interaction. Conclusions These ten themes represent areas that need attention if a clinic or community hospital plans to implement and successfully utilize CDS. In addition, they have implications for workforce education, research, and national-level policy development. The Translational Interaction construct could guide future applied informatics research endeavors. PMID:22333210
Excellence in clinical teaching: knowledge transformation and development required.
Irby, David M
2014-08-01
Clinical teachers in medicine face the daunting task of mastering the many domains of knowledge needed for practice and teaching. The breadth and complexity of this knowledge continue to increase, as does the difficulty of transforming the knowledge into concepts that are understandable to learners. Properly targeted faculty development has the potential to expedite the knowledge transformation process for clinical teachers. Based on my own research in clinical teaching and faculty development, as well as the work of others, I describe the unique forms of clinical teacher knowledge, the transformation of that knowledge for teaching purposes and implications for faculty development. The following forms of knowledge for clinical teaching in medicine need to be mastered and transformed: (i) knowledge of medicine and patients; (ii) knowledge of context; (iii) knowledge of pedagogy and learners, and (iv) knowledge integrated into teaching scripts. This knowledge is employed and conveyed through the parallel processes of clinical reasoning and clinical instructional reasoning. Faculty development can facilitate this knowledge transformation process by: (i) examining, deconstructing and practising new teaching scripts; (ii) focusing on foundational concepts; (iii) demonstrating knowledge-in-use, and (iv) creating a supportive organisational climate for clinical teaching. To become an excellent clinical teacher in medicine requires the transformation of multiple forms of knowledge for teaching purposes. These domains of knowledge allow clinical teachers to provide tailored instruction to learners at varying levels in the context of fast-paced and demanding clinical practice. Faculty development can facilitate this knowledge transformation process. © 2014 John Wiley & Sons Ltd.

Despite growing interest in the importance of, and challenges associated with the involvement of patient and population (IPP) in the process of developing and adapting clinical practice guidelines (CPGs), there is a lack of knowledge about the best method to use. This is especially problematic in the field of rehabilitation, where individuals with disabilities might face many barriers to their involvement in the guideline development and adaptation process. The goal of this pilot trial is to document the acceptability, feasibility and effectiveness of two methods of involving patients with a disability (traumatic brain injury) in CPG development. A single-blind, randomized, crossover pragmatic trial will be performed with 20 patients with traumatic brain injury (TBI). They will be randomized into two groups, and each will try two alternative methods of producing recommendations; a discussion group (control intervention) and a Wiki, a webpage that can be modified by those who have access to it (experimental intervention). The participants will rate the acceptability of the two methods, and feasibility will be assessed using indicators such as the number of participants who accessed and completed the two methods, and the number of support interventions required. Twenty experts, blinded to the method of producing the recommendations, will independently rate the recommendations produced by the participants for clarity, accuracy, appropriateness and usefulness. Our trial will allow for the use of optimal IPP methods in a larger project of adapting guidelines for the rehabilitation of individuals with TBI. Ultimately the results will inform the science of CPG development and contribute to the growing knowledge about IPP in rehabilitation settings. Clinical trial KT Canada 87776.

If institutions of higher education are to produce health professionals whose practice is research based, then students need to be exposed to learning opportunities that include searching for information and critical appraisal. This requires teachers to incorporate the latest research in their teaching. One of the identified strategic goals of a South African university was to produce evidence-based health care practitioners. Evidence-based practice (EBP) requires that health care practitioners plan their actions based on clinically relevant studies and research as opposed to traditional actions that are steeped in opinion. To determine the extent to which academic health care practitioners use "evidence" in their teaching and what they perceived as barriers to the use of EBP. A quantitative design was chosen and a structured questionnaire was used. The areas that were measured included knowledge and attitudes, use of EBP and perceived barriers to the use of EBP. Twenty-three academic health care practitioners completed the questionnaire. Knowledge and attitudes: 80% strongly agreed on a four-point Likert scale, that there is a strong need to incorporate EBP into teaching, with only 48% strongly agreeing that EBP is another perspective of clinical effectiveness. Use of EBP: 73.9% stated that they used EBP in their teaching and 60.9% agreed that it imposes another demand on an already overloaded academic. More than half reported using journals, textbooks, the Internet, colleagues, and the Cochrane library to improve their teaching. Academic health care practitioners attempting to implement EBP have encountered a significant number of barriers in this South African institution. These barriers include lack of knowledge pertaining to EBP, lack of access to research findings, insufficient evidence, and insufficient time.
A Computational Model of Reasoning from the Clinical Literature
Rennels, Glenn D.
1986-01-01
This paper explores the premise that a formalized representation of empirical studies can play a central role in computer-based decision support. The specific motivations underlying this research include the following propositions: 1. Reasoning from experimental evidence contained in the clinical literature is central to the decisions physicians make in patient care. 2. A computational model, based upon a declarative representation for published reports of clinical studies, can drive a computer program that selectively tailors knowledge of the clinical literature as it is applied to a particular case. 3. The development of such a computational model is an important first step toward filling a void in computer-based decision support systems. Furthermore, the model may help us better understand the general principles of reasoning from experimental evidence both in medicine and other domains. Roundsman is a developmental computer system which draws upon structured representations of the clinical literature in order to critique plans for the management of primary breast cancer. Roundsman is able to produce patient-specific analyses of breast cancer management options based on the 24 clinical studies currently encoded in its knowledge base. The Roundsman system is a first step in exploring how the computer can help to bring a critical analysis of the relevant literature to the physician, structured around a particular patient and treatment decision.

Purpose Optical coherence tomography (OCT) has enabled “virtual biopsy” of the living human retina, revolutionizing both basic retina research and clinical practice over the past 25 years. For most of those years, in parallel, adaptive optics (AO) has been used to improve the transverse resolution of ophthalmoscopes to foster in vivo study of the retina at the microscopic level. Here, we review work done over the last 15 years to combine the microscopic transverse resolution of AO with the microscopic axial resolution of OCT, building AO-OCT systems with the highest three-dimensional resolution of any existing retinal imaging modality. Methods We surveyed the literature to identify the most influential antecedent work, important milestones in the development of AO-OCT technology, its applications that have yielded new knowledge, research areas into which it may productively expand, and nascent applications that have the potential to grow. Results Initial efforts focused on demonstrating three-dimensional resolution. Since then, many improvements have been made in resolution and speed, as well as other enhancements of acquisition and postprocessing techniques. Progress on these fronts has produced numerous discoveries about the anatomy, function, and optical properties of the retina. Conclusions Adaptive optics OCT continues to evolve technically and to contribute to our basic and clinical knowledge of the retina. Due to its capacity to reveal cellular and microscopic detail invisible to clinical OCT systems, it is an ideal companion to those instruments and has the demonstrable potential to produce images that can guide the interpretation of clinical findings.

Best practise use in stroke rehabilitation: from trials and tribulations to solutions!
Menon, Anita; Bitensky, Nicol Korner; Straus, Sharon
2010-01-01
This article explores the use of best practises among stroke rehabilitation professionals, salient barriers that influence their knowledge uptake/application and effective knowledge translation (KT) strategies that meet the needs of this clinician group. Relevant literature on evidence-based practise in stroke rehabilitation and the use of KT strategies among rehabilitation professionals is summarised and discussed. Although adherence to rehabilitation guidelines translates into improved patient outcomes, best practises are not routinely applied by clinicians when treating individuals with a stroke. Lack of protected work time to search and appraise the research literature is by far the largest organisational barrier to knowledge uptake/application. Personal barriers, such as the lack of confidence and skills to interpret, synthesise and apply research findings, also limit clinicians' uptake of best practises. Studies involving rehabilitation professionals found that active KT strategies were more effective than passive strategies to produce change in their evidence-based knowledge and practise behaviours. As such, interactive e-learning resources are likely to be a relevant KT solution to meet rehabilitation professionals' specific learning needs, guide their clinical decision-making and ultimately increase their best practise behaviours. We have the knowledge of best practises in stroke rehabilitation, a means to disseminate that knowledge internationally through interactive e-learning resources, and information about effective KT interventions. With these opportunities in place, rehabilitation professionals can expand their capacity by adopting stroke best practises and producing better outcomes for patients.

The need for effective and efficient exchange of clinical knowledge is increasing. Paper based methods for managing clinical knowledge are not meeting the demand for knowledge and this has undoubtedly contributed to the widely reported failures of clinical guidelines. Internet affords both opportunities and dangers for clinical knowledge. Systems such as Wax have demonstrated the importance of intuitive structure in the management of knowledge. We report on a new initiative for the global management of clinical knowledge.

The literature demonstrates that medical residents and practicing physicians have an attitudinal-behavioral discordance concerning their positive attitudes towards clinical practice guidelines (CPG), and the implementation of these guidelines into clinical practice patterns. A pilot study was performed to determine if change in a previously identified CPG compliance factor (accessibility) would produce a significant increase in family medicine resident knowledge and attitude toward the guidelines. The primary study intervention involved placing a summary of the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) and the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (NCEP III) CPGs in all patient (>18 yr.) charts for a period of three months. The JNC VI and NCEP III CPGs were also distributed to each Wayne State family medicine resident, and a copy of each CPG was placed in the preceptor's area of the involved clinics. Identical pre- and post- intervention questionnaires were administered to all residents concerning CPG knowledge and attitude. Post-intervention analysis failed to demonstrate a significant difference in CPG knowledge. A statistically significant post-intervention difference was found in only on attitude question. The barriers to CPG compliance were identified as 1) lack of CPG instruction; 2) lack of critical appraisal ability; 3) insufficient time; 4) lack of CPG accessibility; and 5) lack of faculty modeling. This study demonstrated no significant post intervention changes in CPG knowledge, and only one question that reflected attitude change. Wider resident access to dedicated clinic time, increased faculty modeling, and the implementation of an electronic record/reminder system that uses a team-based approach are compliance factors that should be considered for further investigation. The interpretation of CPG non-compliance will benefit from a causal matrix focused on physician knowledge, attitudes, and behavior. Recent findings in resident knowledge-behavior discordance may direct the future investigation of physician CPG non-compliance away from generalized barrier research, and toward the development of information that maximizes the sense of individual practitioner urgency and certainty.

There is growing awareness that the poor uptake of evidence in health care is not a knowledge-transfer problem but rather one of knowledge production. This issue calls for re-examination of the evidence produced and assumptions that underpin existing knowledge-to-action (KTA) activities. Accordingly, it has been advocated that KTA studies should treat research knowledge and local practical knowledge with analytical impartiality. The purpose of this case report is to illustrate the complexities in an evidence-informed improvement process of organized stroke care in a local rehabilitation setting. A participatory action approach was used to co-create knowledge and engage local therapists in a 2-way knowledge translation and multidirectional learning process. Evidence regarding rehabilitation stroke units was applied in a straightforward manner, as the setting met the criteria articulated in stroke unit reviews. Evidence on early supported discharge (ESD) could not be directly applied because of differences in target group and implementation environment between the local and reviewed settings. Early supported discharge was tailored to the needs of patients severely affected by stroke admitted to the local rehabilitation stroke unit by combining clinical and home rehabilitation (CCHR). Local therapists welcomed CCHR because it helped them make their task-specific training truly context specific. Key barriers to implementation were travel time, logistical problems, partitioning walls between financing streams, and legislative procedures. Improving local settings with available evidence is not a straightforward application process but rather a matter of searching, logical reasoning, and creatively working with heterogeneous knowledge sources in partnership with different stakeholders. Multiple organizational levels need to be addressed rather than focusing on therapists as sole site of change. © 2015 American Physical Therapy Association.
Inside the “Black Box” of a Knowledge Translation Program in Applied Health Research
Heaton, Janet; Day, Jo; Britten, Nicky
2015-01-01
In this article, we present the findings of a participatory realistic evaluation of a 5-year program of health care research intended to promote the translation of knowledge into routine clinical practice. The program was one of the nine pilot Collaborations for Leadership in Applied Health Research and Care funded by the English National Institute for Health Research between 2008 and 2013. Our aim was to delineate the mechanisms by which, and circumstances in which, some projects carried out under the program achieved success in knowledge translation while others were frustrated. Using qualitative methods, we examined how closer collaboration between academics and clinicians worked in four purposefully chosen case studies. In a synthesis of the findings, we produced a “black box” model of how knowledge translation was enabled by the activation of nine mechanisms. These are summarized in the form of five simple rules for promoting knowledge translation through collaborations based on principles of coproduction. PMID:25854617

Clinical knowledge governance: the international perspective.
Garde, Sebastian
2013-01-01
As a basis for semantic interoperability, ideally, a Clinical Knowledge Resource for a clinical concept should be defined formally and defined once in a way that all clinical professions and all countries can agree on. Clinical Knowledge Governance is required to create high-quality, reusable Clinical Knowledge Resources and achieve this aim. Traditionally, this is a time-consuming and cumbersome process, relying heavily on face-to-face meetings and being able to get sufficient input from clinicians. However, in a national or even international space, it is required to streamline the processes involved in creating Clinical Knowledge Resources. For this, a Web 2.0 tool that supports online collaboration of clinicians during their creation and publishing of Clinical Knowledge Resources has been developed. This tool is named the Clinical Knowledge Manager (CKM) and supports the development, review and publication of Clinical Knowledge Resources. Also, post-publication activities such as adding terminology bindings, translating the Clinical Knowledge Resource into another language and republishing it are supported. The acceptance of Clinical Knowledge Resources depends on their quality and being able to determine their quality, for example it is important to know that a broad umber of reviewers from various clinical disciplines have been involved in the development of the Clinical Knowledge Resource. We are still far from realizing the vision of a global repository of a great number of reusable, high-quality Clinical Knowledge Resources, which can provide the basis for broad semantic interoperability between systems. However progress towards this aim is being made around the world.

The purpose of this study was to describe the development of a clinical model for lung cancer patients treated with stereotactic body radiotherapy (SBRT) within a knowledge-based algorithm for treatment planning, and to evaluate the model performance and applicability to different planning techniques, tumor locations, and beam arrangements. 105 SBRT plans for lung cancer patients previously treated at our institution were included in the development of the knowledge-based model (KBM). The KBM was trained with a combination of IMRT, VMAT, and 3D CRT techniques. Model performance was validated with 25 cases, for both IMRT and VMAT. The full KBM encompassed lesions located centrally vs. peripherally (43:62), upper vs. lower (62:43), and anterior vs. posterior (60:45). Four separate sub-KBMs were created based on tumor location. Results were compared with the full KBM to evaluate its robustness. Beam templates were used in conjunction with the optimizer to evaluate the model's ability to handle suboptimal beam placements. Dose differences to organs-at-risk (OAR) were evaluated between the plans gener-ated by each KBM. Knowledge-based plans (KBPs) were comparable to clinical plans with respect to target conformity and OAR doses. The KBPs resulted in a lower maximum spinal cord dose by 1.0 ± 1.6 Gy compared to clinical plans, p = 0.007. Sub-KBMs split according to tumor location did not produce significantly better DVH estimates compared to the full KBM. For central lesions, compared to the full KBM, the peripheral sub-KBM resulted in lower dose to 0.035 cc and 5 cc of the esophagus, both by 0.4Gy ± 0.8Gy, p = 0.025. For all lesions, compared to the full KBM, the posterior sub-KBM resulted in higher dose to 0.035 cc, 0.35 cc, and 1.2 cc of the spinal cord by 0.2 ± 0.4Gy, p = 0.01. Plans using template beam arrangements met target and OAR criteria, with an increase noted in maximum heart dose (1.2 ± 2.2Gy, p = 0.01) and GI (0.2 ± 0.4, p = 0.01) for the nine-field plans relative to KBPs planned with custom beam angles. A knowledge-based model for lung SBRT consisting of multiple treatment modalities and lesion loca-tions produced comparable plan quality to clinical plans. With proper training and validation, a robust KBM can be created that encompasses both IMRT and VMAT techniques, as well as different lesion locations. © 2016 The Authors.

Biosafety is the primary concern in clinical translation of nanomedicine. As an intrinsic ingredient of human blood without immunogenicity and encouraged by its successful clinical application in Abraxane, albumin has been regarded as a promising material to produce nanoparticles for bioimaging and drug delivery. The strategies for synthesizing albumin-based nanoparticles could be generally categorized into five classes: template, nanocarrier, scaffold, stabilizer and albumin-polymer conjugate. This review introduces approaches utilizing albumin in the preparation of nanoparticles and thereby provides scientists with knowledge of goal-driven design on albumin-based nanomedicine.

Knowledge-based computer systems for radiotherapy planning.
Kalet, I J; Paluszynski, W
1990-08-01
Radiation therapy is one of the first areas of clinical medicine to utilize computers in support of routine clinical decision making. The role of the computer has evolved from simple dose calculations to elaborate interactive graphic three-dimensional simulations. These simulations can combine external irradiation from megavoltage photons, electrons, and particle beams with interstitial and intracavitary sources. With the flexibility and power of modern radiotherapy equipment and the ability of computer programs that simulate anything the machinery can do, we now face a challenge to utilize this capability to design more effective radiation treatments. How can we manage the increased complexity of sophisticated treatment planning? A promising approach will be to use artificial intelligence techniques to systematize our present knowledge about design of treatment plans, and to provide a framework for developing new treatment strategies. Far from replacing the physician, physicist, or dosimetrist, artificial intelligence-based software tools can assist the treatment planning team in producing more powerful and effective treatment plans. Research in progress using knowledge-based (AI) programming in treatment planning already has indicated the usefulness of such concepts as rule-based reasoning, hierarchical organization of knowledge, and reasoning from prototypes. Problems to be solved include how to handle continuously varying parameters and how to evaluate plans in order to direct improvements.

An interactive, virtual-patient module was produced on compact disc (CD-ROM) in response to the critical need to increase dental students' clinical exposure to patients with developmental disabilities. A content development team consisting of dental faculty members, parents of children with developmental disabilities, an individual with a developmental disability, and educational specialists developed the interactive, virtual-patient module. The module focused on a young man with congenital deafblindness presenting as a new patient with a painful molar. Students were required to make decisions regarding clinical interactions throughout the module. Differences in both comfort and knowledge level were measured pre- and post-module completion, as well as the dental students' overall satisfaction with the learning experience. Significant results were obtained in students' perceived comfort and knowledge base. Participants reported overall satisfaction using the modules. This study demonstrated that an interactive, multi-media (CD-ROM), virtual patient learning module for dental students could be an effective tool in providing students needed clinical exposure to patients with developmental disabilities.

The biomedical disciplines and the structure of biomedical and clinical knowledge.
Nederbragt, H
2000-11-01
The relation between biomedical knowledge and clinical knowledge is discussed by comparing their respective structures. The knowledge of a disease as a biological phenomenon is constructed by the interaction of facts and theories from the main biomedical disciplines: epidemiology, diagnostics, clinical trial, therapy development and pathogenesis. Although these facts and theories are based on probabilities and extrapolations, the interaction provides a reliable and coherent structure, comparable to a Kuhnian paradigma. In the structure of clinical knowledge, i.e. knowledge of the patient with the disease, not only biomedical knowledge contributes to the structure but also economic and social relations, ethics and personal experience. However, the interaction between each of the participating "knowledges" in clinical knowledge is not based on mutual dependency and accumulation of different arguments from each, as in biomedical knowledge, but on competition and partial exclusion. Therefore, the structure of biomedical knowledge is different from that of clinical knowledge. This difference is used as the basis for a discussion in which the place of technology, evidence-based medicine and the gap between scientific and clinical knowledge are evaluated.
Collaborative research, knowledge and emergence.

We use the notion of emergence to consider the sorts of knowledge that can be produced in a collaborative research project. The notion invites us to see collaborative work as a developmental dynamic system in which various changes constantly occur. Among these we examine two sorts of knowledge that can be produced: scientific knowledge, and collaborative knowledge. We argue that collaborative knowledge can enable researchers to reflectively monitor their collaborative project, so as to encourage its most productive changes. On the basis of examples taken from this special issue, we highlight four modes of producing collaborative knowledge and discuss the possible uses of such knowledge.

Development of de novo alloantibodies against recipient's red blood cell (RBC) antigens by engrafted donor's lymphocytes is a known phenomenon in the setting of allogeneic hematopoietic stem cell transplantation (HSCT). This situation is usually clinically insignificant. We report a case of early clinically relevant hemolytic anemia in a blood group A 1 D+ patient, due to a limited production of anti-D and anti-A 1 produced by nonpreviously sensitized newly engrafted donor's immune system. A 31-year-old Caucasian woman, blood group A 1 , D+, with Hodgkin's lymphoma, received an unmanipulated haploidentical allogeneic peripheral blood HSCT after a nonmyeloablative conditioning regimen. Donor blood group was A 2 B, D-. The patient had an uneventful course until Day +34, when she developed clinically significant hemolytic anemia with a positive direct antiglobulin test. Anti-D and anti-A 1 produced by the donor-engrafted lymphocytes were detected both in serum and in eluate. The hemolysis produced an accelerated group change, turning the patient's ABO group into A 2 B 2 weeks after the detection of the alloantibodies. As the residual patient's RBCs progressively disappeared, anti-D and anti-A 1 production decreased and were not detected in serum by Day +41. This case illustrates that de novo alloantibody production against ABO and D antigens by the newly engrafted donor's lymphocytes can occasionally cause clinically significant anemia. To our knowledge, this is the first case reported of clinically significant hemolytic anemia due to a transient anti-D anti-A 1 alloimmunization after T-cell-repleted haploidentical HSCT. © 2017 AABB.

Background As a response to the criticisms evidence-based practice currently faces, groups of health care researchers and guideline makers have started to call for the appraisal and inclusion of different kinds of knowledge in guideline production (other than randomized controlled trials [RCTs]) to better link with the informal knowledge used in clinical practice. In an ethnographic study, Gabbay and Le May showed that clinicians in everyday practice situations do not explicitly or consciously use guidelines. Instead, they use mindlines: collectively shared, mostly tacit knowledge that is shaped by many sources, including accumulated personal experiences, education (formal and informal), guidance, and the narratives about patients that are shared among colleagues. In this study on informal knowledge, we consider virtual networks of clinicians as representative of the mindlines in the wider medical community, as holders of knowledge, as well as catalysts of knowing. Objective The aim of this study was to explore how informal knowledge and its creation in communities of clinicians can be characterized as opposed to the more structured knowledge produced in guideline development. Methods This study included a qualitative study of postings on three large virtual networks for physicians in the United Kingdom, the Netherlands, and Norway, taking the topic of statins as a case study and covering more than 1400 posts. Data were analyzed thematically with reference to theories of collaborative knowledge construction and communities of practice. Results The dataset showed very few postings referring to, or seeking to adhere to, explicit guidance and recommendations. Participants presented many instances of individual case narratives that highlighted quantitative test results and clinical examination findings. There was an emphasis on outliers and the material, regulatory, and practical constraints on knowledge use by clinicians. Participants conveyed not-so-explicit knowledge as tacit and practical knowledge and used a prevailing style of pragmatic reasoning focusing on what was likely to work in a particular case. Throughout the discussions, a collective conceptualization of statins was generated and reinforced in many contexts through stories, jokes, and imagery. Conclusions Informal knowledge and knowing in clinical communities entail an inherently collective dynamic practice that includes explicit and nonexplicit components. It can be characterized as knowledge-in-context in practice, with a strong focus on casuistry. Validity of knowledge appears not to be based on criteria of consensus, coherence, or correspondence but on a more polyphonic understanding of truth. We contend that our findings give enough ground for further research on how exploring mindlines of clinicians online could help improve guideline development processes. PMID:29396385

Artemisinin-resistant Plasmodium falciparum parasites are rapidly spreading in Southeast Asia, yet nothing is known about their transmission. This knowledge gap and the possibility that these parasites will spread to Africa endanger global efforts to eliminate malaria. Here we produce gametocytes from parasite clinical isolates that displayed artemisinin resistance in patients and in vitro, and use them to infect native and non-native mosquito vectors. We show that contemporary artemisinin-resistant isolates from Cambodia develop and produce sporozoites in two Southeast Asian vectors, Anopheles dirus and Anopheles minimus, and the major African vector, Anopheles coluzzii (formerly Anopheles gambiae M). The ability of artemisinin-resistant parasites to infect such highly diverse Anopheles species, combined with their higher gametocyte prevalence in patients, may explain the rapid expansion of these parasites in Cambodia and neighbouring countries, and further compromise efforts to prevent their global spread.

Considerable knowledge has been gathered on the physiological role of estrogens. However, fairly little information is available on the role of compounds produced in the breakdown process of estrone and estradiol wich may play a role in various diseases associated with estrogen impact. To date, approximately 15 extragonadal estrogen-related compounds have been identified. These metabolites may exert protective, or, instead, pro-inflammatory and/or pro-oncogenic activity in a tissue-specific manner. Systemic and local estrogen metabolite levels are not necesserily correlated, which may promote the diagnostic significance of the locally produced estrogen metabolites in the future. The aim of the present study is a bibliographic review of the extragonadal metabolome in peripheral tissues, and to highlight the role of the peripheral tissue homeostasis of estrogens as well as the non-hormonal biological activity and clinical significance of the estrogen metabolome.

Attention to Local Health Burden and the Global Disparity of Health Research

Most studies on global health inequality consider unequal health care and socio-economic conditions but neglect inequality in the production of health knowledge relevant to addressing disease burden. We demonstrate this inequality and identify likely causes. Using disability-adjusted life years (DALYs) for 111 prominent medical conditions, assessed globally and nationally by the World Health Organization, we linked DALYs with MEDLINE articles for each condition to assess the influence of DALY-based global disease burden, compared to the global market for treatment, on the production of relevant MEDLINE articles, systematic reviews, clinical trials and research using animal models vs. humans. We then explored how DALYs, wealth, and the production of research within countries correlate with this global pattern. We show that global DALYs for each condition had a small, significant negative relationship with the production of each type of MEDLINE articles for that condition. Local processes of health research appear to be behind this. Clinical trials and animal studies but not systematic reviews produced within countries were strongly guided by local DALYs. More and less developed countries had very different disease profiles and rich countries publish much more than poor countries. Accordingly, conditions common to developed countries garnered more clinical research than those common to less developed countries. Many of the health needs in less developed countries do not attract attention among developed country researchers who produce the vast majority of global health knowledge—including clinical trials—in response to their own local needs. This raises concern about the amount of knowledge relevant to poor populations deficient in their own research infrastructure. We recommend measures to address this critical dimension of global health inequality. PMID:24691431

The traditional use of medicinal plants for treatment of infectious diseases by an indigenous Mbyá-Guarani tribe from South Brazil was assessed by evaluating the antibiotic and antibiofilm activities against relevant bacterial pathogens. Aqueous extracts from 10 medicinal plants were prepared according to indigenous Mbyá-Guarani traditional uses. To evaluate antibiotic (OD600) and antibiofilm (crystal violet method) activities, Pseudomonas aeruginosa ATCC 27853, Staphylococcus epidermidis ATCC 35984 and seven multi-drug resistant Klebsiella pneumoniae carbapenemase (KPC)-producing bacterial clinical isolates were challenged with the extracts. Furthermore, the susceptibility profile of KPC-producing bacteria and the ability of these isolates to form biofilm were evaluated. The plants Campomanesia xanthocarpa, Maytenus ilicifolia, Bidens pilosa and Verbena sp. showed the best activity against bacterial growth and biofilm formation. The majority of KPC-producing isolates, which showed strong ability to form biofilm and a multidrug resistance profile, was inhibited by more than 50% by some extracts. The Enterobacter cloacae (KPC 05) clinical isolate was the only one resistant to all extracts. This study confirms the importance of indigenous traditional medicinal knowledge and describes for the first time the ability of these plants to inhibit biofilm formation and/or bacterial growth of multi-drug resistant KPC-producing isolates.

The pharma-industries are facing a number of crucial business issues to improve operational excellence in product time-to-market and wide regulatory compliance. These organizations own, produce, and manipulate a lot of knowledge. The new regulations by Health Authorities (HA) to pharma-industries should make the content and format of new drug application uniform worldwide. In this paper we suggest a novel approach of a pharma-industry to capture, process, and transmit clinical data electronically. The approach begins with an analysis of the knowledge generation points, some of them being outside the company. Implementations are grounded on the use of a de facto standard platform being Microsoft, having acceptable cost levels. The proposed infrastructure is integrated into existing company environment and technological platform, minimizing cost and risks, but improving efficiency and efficacy of new drug dossier compilation.

To consider the currently available knowledge and understanding of the symptom of urgency. Each faculty member reviewed the literature base of a different aspect of urgency and along with their personal clinical experience provided a base of evidence for discussion. This overview summarises relevant published literature and the current clinical experience of the authors. Whilst the mechanisms producing the sensation of urgency are still not fully understood and we are working within a definition that may complicate measurement and treatment, our pressing need is to effectively manage our patients for whom the practical nature of urgency can be all too apparent. Health care professionals have an important role to play today in helping to alleviate the widespread problem of urgency and its consequences.
XML, Ontologies, and Their Clinical Applications.
Yu, Chunjiang; Shen, Bairong
2016-01-01
The development of information technology has resulted in its penetration into every area of clinical research. Various clinical systems have been developed, which produce increasing volumes of clinical data. However, saving, exchanging, querying, and exploiting these data are challenging issues. The development of Extensible Markup Language (XML) has allowed the generation of flexible information formats to facilitate the electronic sharing of structured data via networks, and it has been used widely for clinical data processing. In particular, XML is very useful in the fields of data standardization, data exchange, and data integration. Moreover, ontologies have been attracting increased attention in various clinical fields in recent years. An ontology is the basic level of a knowledge representation scheme, and various ontology repositories have been developed, such as Gene Ontology and BioPortal. The creation of these standardized repositories greatly facilitates clinical research in related fields. In this chapter, we discuss the basic concepts of XML and ontologies, as well as their clinical applications.
Recommendations Service for Chronic Disease Patient in Multimodel Sensors Home Environment

Abstract With advanced technologies in hand, there exist potential applications and services built around monitoring activities of daily living (ADL) of elderly people at nursing homes. Most of the elderly people in these facilities are suffering from different chronic diseases such as dementia. Existing technologies are mainly focusing on non-medication interventions and monitoring of ADL for addressing loss of autonomy or well-being. Monitoring and managing ADL related to cognitive behaviors for non-medication intervention are very effective in improving dementia patients' conditions. However, cognitive functions of patients can be improved if appropriate recommendations of medications are delivered at a particular time. Previously we developed the Secured Wireless Sensor Network Integrated Cloud Computing for Ubiquitous-Life Care (SC3). SC3 services were limited to monitoring ADL of elderly people with Alzheimer's disease and providing non-medication recommendations to the patient. In this article, we propose a system called the Smart Clinical Decision Support System (CDSS) as an integral part of the SC3 platform. Using the Smart CDSS, patients are provided with access to medication recommendations of expert physicians. Physicians are provided with an interface to create clinical knowledge for medication recommendations and to observe the patient's condition. The clinical knowledge created by physicians as the knowledge base of the Smart CDSS produces recommendations to the caregiver for medications based on each patient's symptoms. PMID:25559934

Multimedia Workstations: Electronic Assistants for Health-Care Professionals.
Degoulet, P; Jean, F-C; Safran, C
1996-01-01
The increasing costs of health care and the economic reality has produced an interesting paradox for the health professional to perform more clinical work with fewer support personnel. Moreover, an explosion of the knowledge-base that underlies sound clinical care not only makes effective time management critical, but also knowledge management compelling. A multimedia workstation is an electronic assistant for the busy health professional that can help with administrative tasks and give access to clinical information and knowledge networks. The multimedia nature of processed information reflects an evolution of medical technologies that involve more and more complex objects such as video sequences or digitized signals. Analysis of the 445 Medline-indexed publications for the January 1991 to December 1994 period, that included the word "workstation" either in their title or in their abstract, helps in refining objectives and challenges both for health professionals and decision makers. From an engineering perspective, development of a workstation requires the integration into the same environments of tools to localize, access, manipulate and communicate the required information. The long-term goal is to establish an easy access in a collaborative working environment that gives the end-user the feeling of a single virtual health enterprise, driven by an integrated computer system when the information system relies on a set of heterogeneous and geographically distributed components. Consequences in terms of migration from traditional client/server architectures to more client/network architectures are considered.

Many challenges to adaptation decision-making and action have been identified across peer-reviewed and gray literature. These challenges have primarily focused on the use of climate knowledge for adaptation decision-making, the process of adaptation decision-making, and the needs of the decision-maker. Studies on climate change knowledge systems often discuss the imperative role of climate knowledge producers in adaptation decision-making processes and stress the need for producers to engage in knowledge co-production activities and to more effectively meet decision-maker needs. While the influence of climate knowledge producers on the co-production of science for adaptation decision-making is well-recognized, hardly any research has taken a direct approach to analyzing the challenges that climate knowledge producers face when undertaking science co-production. Those challenges can influence the process of knowledge production and may hinder the creation, utilization, and dissemination of actionable knowledge for adaptation decision-making. This study involves semi-structured interviews, focus groups, and participant observations to analyze, identify, and contextualize the challenges that climate knowledge producers in Sweden face as they endeavor to create effective climate knowledge systems for multiple contexts, scales, and levels across the European Union. Preliminary findings identify complex challenges related to education, training, and support; motivation, willingness, and culture; varying levels of prioritization; professional roles and responsibilities; the type and amount of resources available; and professional incentive structures. These challenges exist at varying scales and levels across individuals, organizations, networks, institutions, and disciplines. This study suggests that the creation of actionable knowledge for adaptation decision-making is not supported across scales and levels in the climate knowledge production landscape. Additionally, enabling the production of actionable knowledge for adaptation decision-making requires multi-level effort beyond the individual level.

The growing scientific knowledge and technology development are leading to radical changes in biological and medical research. The prevalent lines of development deal with a pragmatic evolution of controlled clinical trials, a massive diffusion of observational research, which is progressively incorporated in clinical practice, new models and designs of clinical research, the systematic use of information technology to build up vast networks of medical centers producing huge amounts of shared data to be managed through the big data methodology, personalized as well as precision medicine, a reshaped physician-patient relationship based on a co-working principle. All this is leading to profound changes in public health governance, a renewal of clinical epidemiology and prevention, a modified structure of several specific sectors of medical care, hopefully guided by scientific evidences. A few aspects of such an evolving picture are discussed in this article.
The placebo puzzle: examining the discordant space between biomedical science and illness/healing.
Pohlman, Shawn; Cibulka, Nancy J; Palmer, Janice L; Lorenz, Rebecca A; SmithBattle, Lee
2013-03-01
The placebo response presents an enigma to biomedical science: how can 'inert' or 'sham' procedures reduce symptoms and produce physiological changes that are comparable to prescribed treatments? In this study, we examine this puzzle by explicating the discordant space between the prevailing biomedical paradigm, which focuses on a technical understanding of diagnosis and treatment, and a broader understanding of illness and healing as relational and embodied. Although biomedical achievements are impressive, the knowledge resulting from this paradigm is limited by its ontological and epistemological assumptions. When the body and world are objectified, illness meanings, therapeutic relationships, and healing practices are dismissed or distorted. In spite of a robust critique of the tenets of biomedicine for guiding practice, the biomedical paradigm retains a tenacious hold on evidence-based medicine and nursing, downplaying our clinical understanding of the sentient body, patients' life-worlds, and illness and healing. In reality, skilled nurses rely on multiple forms of knowledge in providing high-quality care to particular patients. Clinically wise nurses integrate their experience and knowledge of patients' priorities, fears, and illness trajectories along with biomedical findings to make astute judgments and promote health and healing. © 2012 Blackwell Publishing Ltd.
Nurse teachers' knowledge in curriculum planning and implementation.
Thomas, Eiddwen; Davies, Brian
2006-10-01
Nurses are required to base care on research evidence but research findings on nursing practice often suggest that the linkage is poor and ritualistic routines often prevail. The study explored the origin and nature of knowledge utilised by nurse teachers when developing and implementing a curriculum. In a single, ethnographic case study data were collected from two curriculum development and two curriculum implementation groups, using interviews, participant observation and documents. The study drew directly on Bernstein's theory of the pedagogic device and cultural reproduction. Findings suggested that even though nurse education appears to be dominated by policies and guidelines produced by state agencies, it was teachers operating at institutional and classroom levels who determined what was delivered to student nurses as they relied upon their experience of teaching and clinical practice to plan and implement curriculum. Notwithstanding both national and local aspirations to the contrary, teaching and assessment practices were mostly teacher- rather than student-centred, with heavy reliance on propositional knowledge. The practices identified within this study may induce approaches to learning that may be antithetical to delivering research based care within a prevailing climate that advocates evidence-based practice, clinical effectiveness and governance.
Student-written single-best answer questions predict performance in finals.

Single-best answer (SBA) questions are widely used for assessment in medical schools; however, often clinical staff have neither the time nor the incentive to develop high-quality material for revision purposes. A student-led approach to producing formative SBA questions offers a potential solution. Cardiff University School of Medicine students created a bank of SBA questions through a previously described staged approach, involving student question-writing, peer-review and targeted senior clinician input. We arranged questions into discrete tests and posted these online. Student volunteer performance on these tests from the 2012/13 cohort of final-year medical students was recorded and compared with the performance of these students in medical school finals (knowledge and objective structured clinical examinations, OSCEs). In addition, we compared the performance of students that participated in question-writing groups with the performance of the rest of the cohort on the summative SBA assessment. Often clinical staff have neither the time nor the incentive to develop high-quality material for revision purposes Performance in the end-of-year summative clinical knowledge SBA paper correlated strongly with performance in the formative student-written SBA test (r = ~0.60, p <0.01). There was no significant correlation between summative OSCE scores and formative student-written SBA test scores. Students who wrote and reviewed questions scored higher than average in the end-of-year summative clinical knowledge SBA paper. Student-written SBAs predict performance in end-of-year SBA examinations, and therefore can provide a potentially valuable revision resource. There is potential for student-written questions to be incorporated into summative examinations. © 2015 John Wiley & Sons Ltd.

Medical knowledge encompasses both conceptual (facts or "what" information) and procedural knowledge ("how" and "why" information). Conceptual knowledge is known to be an essential prerequisite for clinical problem solving. Primarily, medical students learn from textbooks and often struggle with the process of applying their conceptual knowledge to clinical problems. Recent studies address the question of how to foster the acquisition of procedural knowledge and its application in medical education. However, little is known about the factors which predict performance in procedural knowledge tasks. Which additional factors of the learner predict performance in procedural knowledge? Domain specific conceptual knowledge (facts) in clinical nephrology was provided to 80 medical students (3rd to 5th year) using electronic flashcards in a laboratory setting. Learner characteristics were obtained by questionnaires. Procedural knowledge in clinical nephrology was assessed by key feature problems (KFP) and problem solving tasks (PST) reflecting strategic and conditional knowledge, respectively. Results in procedural knowledge tests (KFP and PST) correlated significantly with each other. In univariate analysis, performance in procedural knowledge (sum of KFP+PST) was significantly correlated with the results in (1) the conceptual knowledge test (CKT), (2) the intended future career as hospital based doctor, (3) the duration of clinical clerkships, and (4) the results in the written German National Medical Examination Part I on preclinical subjects (NME-I). After multiple regression analysis only clinical clerkship experience and NME-I performance remained independent influencing factors. Performance in procedural knowledge tests seems independent from the degree of domain specific conceptual knowledge above a certain level. Procedural knowledge may be fostered by clinical experience. More attention should be paid to the interplay of individual clinical clerkship experiences and structured teaching of procedural knowledge and its assessment in medical education curricula.
Nurses' competence in genetics: An integrative review.
Wright, Helen; Zhao, Lin; Birks, Melanie; Mills, Jane
2018-01-29
The aim of this integrative review was to update a mixed method systematic review by Skirton, O'Connor, and Humphreys (2012) that reported on nurses' levels of competence in using genetics in clinical practice. Three electronic databases were searched using selected key words. Research studies published in English between January 2011 and September 2017 reporting levels of nurse competence in genetics or genomics were eligible for inclusion. The selected studies were subjected to thematic analysis. Three main themes were identified: (i) genomic knowledge and utilization, (ii) perceived relevance to practice, and (iii) genomic education. While the reviewed papers produced varied findings, many nurses were shown to have poor genomic knowledge and/or competency, and yet there was a consensus that most nurses believe genomics is important to their practice. The present review indicated that in the past 5 years nurses have made minimal progress toward achieving the core genomic competencies appropriate for clinical practice. © 2018 John Wiley & Sons Australia, Ltd.
Patient consent to publication and data sharing in industry and NIH-funded clinical trials.

Participants are recruited into clinical trials under the assumption that the research will contribute to medical knowledge. Therefore, non-publication trials-and, more recently, lack of data sharing-are widely considered to violate the trust of trial participants. Existing practices regarding patient consent to publication and data sharing have not been evaluated. Analyzing informed consent forms (ICFs), we studied what trial participants were told regarding investigators' intention to contribute to medical knowledge, publish trial results, and share de-identified trial data. We obtained 98 ICFs of industry-funded pre-marketing trials for all (17) antibiotics approved by the European Medicines Agency and 46 ICFs of publicly funded trials from the National Heart, Lung and Blood Institute Biologic Specimen and Data Repository Information Coordinating Center (BioLINCC) data repository. Three authors independently reviewed ICFs to identify and extract what was stated or implied regarding: (1) publication of results; (2) sharing de-identified data; (3) data ownership; (4) confidentiality of identifiable data; and (5) whether the trial will produce knowledge that offers public benefit. Consensus was obtained from the two reviewers with the greatest overall agreement on all five measures. Disagreements were resolved through discussion among all authors. Four (3%) trials indicated a commitment to publish trial results; 140 (97%) did not commit to publishing trial results; six (4%) indicated a commitment to share de-identified data with third party researchers. Commitments to share were more common in publicly funded trials than industry-funded trials (7% vs 3%). A total of 103 (72%) ICFs indicated the trials will or may produce knowledge that offers public benefits, while 131 (91%) ICFs left unstated who "owned" trial data; of those with statements, the sponsor always claimed ownership. Patient confidentiality was guaranteed in 137 (95%) trials. Our results suggest that consent forms rarely disclose investigators' intentions regarding the sharing of de-identified data or publication of trial results.

The advent of advanced therapies in the pharmaceutical industry has moved the spotlight into virus-like particles and viral vectors produced in cell culture holding great promise in a myriad of clinical targets, including cancer prophylaxis and treatment. Even though a couple of cases have reached the clinic, these products have yet to overcome a number of biological and technological challenges before broad utilization. Concerning the manufacturing processes, there is significant research focusing on the optimization of current cell culture systems and, more recently, on developing scalable downstream processes to generate material for pre-clinical and clinical trials. We review the current options for downstream processing of these complex biopharmaceuticals and underline current advances on knowledge-based toolboxes proposed for rational optimization of their processing. Rational tools developed to increase the yet scarce knowledge on the purification processes of complex biologicals are discussed as alternative to empirical, "black-boxed" based strategies classically used for process development. Innovative methodologies based on surface plasmon resonance, dynamic light scattering, scale-down high-throughput screening and mathematical modeling for supporting ion-exchange chromatography show great potential for a more efficient and cost-effective process design, optimization and equipment prototyping.

Both the underuse and overuse of clinical preventive services relative to evidence-based guidelines are a public health concern. Informed consumers are an important foundation of many components of the Affordable Care Act, including coverage mandates for proven clinical preventive services recommended by the US Preventive Services Task Force. Across sociodemographic groups, however, knowledge of and positive attitudes toward evidence-based guidelines for preventive care are extremely low. Given the demonstrated low levels of consumers' knowledge of and trust in guidelines, coupled with their strong preference for involvement in preventive care decisions, better education and decision-making support for evidence-based preventive services are greatly needed. Both the underuse and overuse of clinical preventive services are a serious public health problem. The goal of our study was to produce population-based national data that could assist in the design of communication strategies to increase knowledge of and positive attitudes toward evidence-based guidelines for clinical preventive services (including the US Preventive Services Task Force, USPSTF) and to reduce uncertainty among patients when guidelines change or are controversial. In late 2013 we implemented an Internet-based survey of a nationally representative sample of 2,529 adults via KnowledgePanel, a probability-based survey panel of approximately 60,000 adults, statistically representative of the US noninstitutionalized population. African Americans, Hispanics, and those with less than a high school education were oversampled. We then conducted descriptive statistics and multivariable logistic regression analysis to identify the prevalence of and sociodemographic characteristics associated with key knowledge and attitudinal variables. While 36.4% of adults reported knowing that the Affordable Care Act requires insurance companies to cover proven preventive services without cost sharing, only 7.7% had heard of the USPSTF. Approximately 1 in 3 (32.6%) reported trusting that a government task force would make fair guidelines for preventive services, and 38.2% believed that the government uses guidelines to ration health care. Most of the respondents endorsed the notion that research/scientific evidence and expert medical opinion are important for the creation of guidelines and that clinicians should follow guidelines based on evidence. But when presented with patient vignettes in which a physician made a guideline-based recommendation against a cancer-screening test, less than 10% believed that this recommendation alone, without further dialogue and/or the patient's own research, was sufficient to make such a decision. Given these demonstrated low levels of knowledge and mistrust regarding guidelines, coupled with a strong preference for shared decision making, better consumer education and decision supports for evidence-based guidelines for clinical preventive services are greatly needed. © 2016 Milbank Memorial Fund.

The prevalence of diabetes in China has surged from 0.67% before 1980 to 11.6% currently. It is even higher than the prevalence in the United States. Certainly, China's economic open-ups, improving living standard, and modernization have propagated the surge. From a traditional public-health point of view, increased food intake and decreased exercise were the main contributors. A new knowledge of colon microbiota could be applied to provide a second harvest of food energy; for example, large molecules of carbohydrates, which are undigested by the stomach and small intestine, produce by-products that the body can absorb in the colon. Colon microbiota can ferment these carbohydrates to the short-chain fatty acid butyrate. This is an energy source that may even cause nonalcoholic fatty liver. How these colon microbiota contribute to the surge of diabetes and whether this new knowledge can be used to control diabetes and metabolic syndrome are questions for future scientific studies. Clinically, however, colon microbiota have had immediate applications; fecal microbiota have been transplanted from healthy persons to treat recurrent Clostridium difficile infection at Mayo Clinic. In addition, a stool biobank of healthy persons was established at Mayo Clinic for future clinical applications. © 2016 by the Association of Clinical Scientists, Inc.
Challenging Nurses’ Cultural Competence of Disability to Improve Interpersonal Interactions
Roscigno, Cecelia I.
2013-01-01
Worldwide, at least 6.9 billion people have an impairment producing health condition (IPHC). Insensitive encounters with health care providers (HCPs) can result in negative appraisals, fear, and avoidance, but little is known about what things are commonly perceived as insensitive. A review of published narratives describing negative encounters with HCPs was conducted. Narrative analysis was used to compare, contrast, and synthesize six themes describing the common negative encounters: (a) ignoring or minimizing their knowledge; (b) detached interpersonal interactions; (c) placing a negative skew on their life quality; (d) a lack of HCP knowledge related to their complete needs; (e) assuming they should be asexual and childless; and, (f) an inherent power differential. The medical model of disability is perceived by individuals with IPHCs to inform negative encounters perceived as insensitive. This preliminary knowledge is important so we can address education needs, plan future research questions, and establish clinical practice improvements. PMID:23291869

Background Laser plays an increasingly prominent role in skin rejuvenation. The advent of fractional photothermolysis revolutionizes its application. Microcolumns of skin are focally injured, leaving intervening normal skin to facilitate rapid wound healing and orderly tissue remodeling. The Problem Even with the popularity of fractional laser devices, we still have limited knowledge about the ideal treatment parameters and postlaser wound care. Basic/Clinical Science Advances Many clinicians believe that higher microbream energy in fractional laser devices results in better clinical outcome. Two recent studies argue against this assumption. One article demonstrates that lower fluence can induce comparable molecular changes with fewer side effects. Another study corroborates this by showing that lower-density settings produce similar clinical outcome in scar remodeling as higher-density ones, but with fewer side effects. To shed light on the optimal post-treatment wound care regimen from fractional ablative resurfacing, another paper shows that platelet-rich plasma (PRP) can reduce transepidermal water loss and skin color changes within 1 month after treatment. Clinical Care Relevance For fractional nonablative resurfacing, lower settings in fluence or density may produce similar dermal remodeling as higher settings and with a better side-effect profile. Moreover, autologous PRP appears to expedite wound healing after fractional ablative resurfacing. Conclusion Lower microbeam energy in fractional laser resurfacing produces similar molecular changes and clinical outcome with fewer side effects. The findings might portend a shift in the paradigm of treatment parameters. Autologous PRP can facilitate better wound healing, albeit modestly. Long-term follow-ups and larger studies are necessary to confirm these findings. PMID:24527307

Objectives (1) To determine the impact of a digital educational intervention on the knowledge, attitudes, confidence and behavioural intention of registered children’s nurses working with children and young people (CYP) admitted with self-harm. (2) To explore the perceived impact, suitability and usefulness of the intervention. Intervention A digital educational intervention that had been co-produced with CYP service users, registered children’s nurses and academics. Setting A prospective, uncontrolled, intervention study with preintervention and postintervention measurement, conducted at a large acute NHS Trust in the UK. Participants From a pool of 251 registered children’s nurses and 98 participants were recruited to complete the intervention (response rate=39%). At follow-up, 52% of participants completed the postintervention questionnaire, with 65% (n=33) of those reporting to have completed the digital educational intervention. Primary outcome measures Attitude towards self-harm in CYP was measured using a 13-item questionnaire; knowledge of self-harm in CYP was measured through an adapted 12-item questionnaire; confidence in different areas of practice was measured through Likert Scale responses; self-efficacy for working with CYP who have self-harmed was measured through an adapted version of the Self-efficacy Towards Helping Scale; clinical behavioural intention was measured by the Continuing Professional Development Reaction Questionnaire. Semistructured interviews were undertaken with a purposive sample of participants. Results For those who completed the intervention (n=33), improvements were observed in knowledge (effect size, ES: 0.69), confidence, and in some domains relating to attitudes (effectiveness domain-ES: 0.49), and clinical behavioural intention (belief about consequences-ES:0.49; moral norm-ES: 0.43; beliefs about capability-ES: 0.42). Qualitative findings suggest participants experienced skill development, feelings of empowerment and reflection on own practice. Conclusions The effect of the intervention is promising and demonstrates the potential it has in improving registered children’s nurse’s knowledge, confidence and attitudes. However, further testing is required to confirm this. PMID:28473515

The ubiquity of DNA sequencing and the advent of medical imaging, electronic health records, and "omics" technologies have produced a deluge of data. Making meaning of those data-creating scientific knowledge and useful clinical information-will vastly exceed the capacity of even the largest institutions. Data must be shared to achieve the promises of genomic science and precision medicine. © 2017 Cook-Deegan and McGuire; Published by Cold Spring Harbor Laboratory Press.
An occult aldosterone-producing adenoma initially presenting as hyperosmolar hyperglycaemic state.
Kuo, Feng-Chih; Hung, Yi-Jen; Hsieh, Chang-Hsun; Hsiao, Fone-Ching
2012-09-01
Aldosterone-producing adenoma (APA), one of the most common causes of primary hyperaldosteronism, is clinically characterized by hypertension, increased sodium retention, increased potassium excretion and altered glucose metabolism. APA can also manifest in the form of hyperosmolar hyperglycaemic state (HHS), which is a life-threatening acute diabetic complication. Infection and inadequate fluid replacement are the common precipitating and predisposing factors for the occurrence of HHS. Here, we report a case of occult APA with the initial presentation of HHS, in which an unusually rapid correction of diabetes was observed after correct diagnosis and surgical resection of the APA. To our knowledge, this is the first case with such manifestations and outcome.

Clinical decision support (CDS) knowledge, embedded over time in mature medical systems, presents an interesting and complex opportunity for information organization, maintenance, and reuse. To have a holistic view of all decision support requires an in-depth understanding of each clinical system as well as expert knowledge of the latest evidence. This approach to clinical decision support presents an opportunity to unify and externalize the knowledge within rules-based decision support. Driven by an institutional need to prioritize decision support content for migration to new clinical systems, the Center for Knowledge Management and Health Information Technology teams applied their unique expertise to extract content from individual systems, organize it through a single extensible schema, and present it for discovery and reuse through a newly created Clinical Support Knowledge Acquisition and Archival Tool (CS-KAAT). CS-KAAT can build and maintain the underlying knowledge infrastructure needed by clinical systems.

Systems medicine, using and adapting methods and approaches as developed within systems biology, promises to be essential in ongoing efforts of realizing and implementing personalized medicine in clinical practice and research. Here we review and critically assess these opportunities and challenges using our work on COPD as a case study. We find that there are significant unresolved biomedical challenges in how to unravel complex multifactorial components in disease initiation and progression producing different clinical phenotypes. Yet, while such a systems understanding of COPD is necessary, there are other auxiliary challenges that need to be addressed in concert with a systems analysis of COPD. These include information and communication technology (ICT)-related issues such as data harmonization, systematic handling of knowledge, computational modeling, and importantly their translation and support of clinical practice. For example, clinical decision-support systems need a seamless integration with new models and knowledge as systems analysis of COPD continues to develop. Our experience with clinical implementation of systems medicine targeting COPD highlights the need for a change of management including design of appropriate business models and adoption of ICT providing and supporting organizational interoperability among professional teams across healthcare tiers, working around the patient. In conclusion, in our hands the scope and efforts of systems medicine need to concurrently consider these aspects of clinical implementation, which inherently drives the selection of the most relevant and urgent issues and methods that need further development in a systems analysis of disease.
Patient or consumer? The colonization of the psychiatric clinic.
Evans, Alicia M
2005-12-01
Information is given a privileged place in the psychiatric clinic, as illustrated by the prevalence and volume of data to be collected and forms to be completed by psychiatric nurses. Information though is different to knowledge. The present paper argues that information is part of a managerial discourse that implies commodification whereas knowledge is part of a clinical discourse that allows room for the suffering of the patient. Information belongs to the discourse of managerialism, one that positions the patient as customer/consumer and in doing so renders them unsuffering. The patient's suffering is silenced by their construction as a consumer. The discourse of managerialism seeks a complete data set of information. By way of contrast, another discourse, that of psychoanalysis offers the institution the idea that there are always holes, gaps, and uncertainty. The idea of uncertainty, gaps, things remaining unknown and a limit sits uncomfortably with the dominant discourse of managerialism; one that demands no limits, complete data sets, and many satisfied customers. This market model of managerialism denies the potential of the therapeutic relationship; that something curative might be produced via the transference. In addition, the managerialist discourse potentially positions the patient as both illegitimate and unsuffering.

As a response to the criticisms evidence-based practice currently faces, groups of health care researchers and guideline makers have started to call for the appraisal and inclusion of different kinds of knowledge in guideline production (other than randomized controlled trials [RCTs]) to better link with the informal knowledge used in clinical practice. In an ethnographic study, Gabbay and Le May showed that clinicians in everyday practice situations do not explicitly or consciously use guidelines. Instead, they use mindlines: collectively shared, mostly tacit knowledge that is shaped by many sources, including accumulated personal experiences, education (formal and informal), guidance, and the narratives about patients that are shared among colleagues. In this study on informal knowledge, we consider virtual networks of clinicians as representative of the mindlines in the wider medical community, as holders of knowledge, as well as catalysts of knowing. The aim of this study was to explore how informal knowledge and its creation in communities of clinicians can be characterized as opposed to the more structured knowledge produced in guideline development. This study included a qualitative study of postings on three large virtual networks for physicians in the United Kingdom, the Netherlands, and Norway, taking the topic of statins as a case study and covering more than 1400 posts. Data were analyzed thematically with reference to theories of collaborative knowledge construction and communities of practice. The dataset showed very few postings referring to, or seeking to adhere to, explicit guidance and recommendations. Participants presented many instances of individual case narratives that highlighted quantitative test results and clinical examination findings. There was an emphasis on outliers and the material, regulatory, and practical constraints on knowledge use by clinicians. Participants conveyed not-so-explicit knowledge as tacit and practical knowledge and used a prevailing style of pragmatic reasoning focusing on what was likely to work in a particular case. Throughout the discussions, a collective conceptualization of statins was generated and reinforced in many contexts through stories, jokes, and imagery. Informal knowledge and knowing in clinical communities entail an inherently collective dynamic practice that includes explicit and nonexplicit components. It can be characterized as knowledge-in-context in practice, with a strong focus on casuistry. Validity of knowledge appears not to be based on criteria of consensus, coherence, or correspondence but on a more polyphonic understanding of truth. We contend that our findings give enough ground for further research on how exploring mindlines of clinicians online could help improve guideline development processes. ©Sietse Wieringa, Eivind Engebretsen, Kristin Heggen, Trisha Greenhalgh.

From clinical trial to prescription.
Carpenter, William T
2002-03-01
There are many steps between drug discovery and prescribing for a patient. Each step has problems. In this issue of ARCHIVES, Klein and colleagues propose changes in clinical trials that would result in more meaningful information for the treating physician. Of particular importance is the gap between what a physician needs to know and what is produced in the clinical trials that leads to approval of a new drug by the US Food and Drug Administration (FDA). Their recommendations for improving clinical trials are cogent, but broad-based implementation depends on an organizational structure and political effectiveness not presently in place. Most important, as the authors note, is an effective work group representing industry, regulatory agencies, and academic and federal science, addressing clinical trials issues with public participation. While improved quality and relevance of data from clinical trials will strengthen the scientific foundation of pharmacotherapy, other problems impede the delivery of objective information to the treating physician. Most hotly debated is the role of money in the creation and dissemination of knowledge.

Background Food-drug interactions can produce undesirable outcomes during the therapy process. The pharmacist is responsible for providing patients counseling about common food-drug interactions. Knowledge of such interactions is important to avoid their occurrence. Objective This study aimed to assess the knowledge and awareness of community pharmacists about common food-drug interactions. Setting Pharmacists working in community pharmacies across Northern Palestine. Method This is a cross-sectional study, which involved a convenience sample of 259 pharmacists working in community pharmacies in Palestine. A self-administered questionnaire consisted of 29 questions (mainly yes/no questions) was used to assess pharmacists' knowledge towards the most common and clinically significant interactions between food and medicines. Main outcome measure Pharmacists' issues related to the knowledge of food drug interactions were evaluated. Results A total of 320 questionnaires were distributed of which 259 were completed providing a response rate 80.9%. One pharmacist from each community pharmacy was asked to complete the questionnaire. The overall knowledge score of food-drug interactions for the pharmacists was 17.9 (61.7%) out of a possible maximum of 29. The pharmacists surveyed in this study have demonstrated good knowledge of some interactions; but poor knowledge of others. Conclusion Pharmacists' knowledge about common food-drug interactions is inadequate. These findings support the need for training and educational courses for pharmacists regarding food-drug interactions.

Salmonella and Shiga toxin-producing Escherichia coli are two of the main causes of foodborne disease globally, and while they have been implicated as possible causes of foodborne disease within the Caribbean region, the actual incidence is unknown. Trinidad and Tobago, one of the larger countries in the Caribbean, has an estimated annual foodborne disease burden of over 100,000 cases and, similar to other countries, the etiology of most of these cases is unknown. Both pathogens can reside as part of the normal gastrointestinal microflora of many wild and domestic animals, with animals acting as reservoirs, spillover hosts, or dead-end hosts. Carriage in animal species can be asymptomatic or, in the case of Salmonella in particular, there may be clinical manifestation in animals, which resemble the disease seen in humans. In this review, we will focus on the epidemiology of these two foodborne pathogens in Trinidad and Tobago and identify any knowledge gaps in the published literature. The filling of this critical knowledge void is essential for the development and implementation of appropriate mechanisms to reduce the dissemination and transmission of these pathogens, not only in Trinidad and Tobago, but also in the wider Caribbean.

Background Medical knowledge encompasses both conceptual (facts or “what” information) and procedural knowledge (“how” and “why” information). Conceptual knowledge is known to be an essential prerequisite for clinical problem solving. Primarily, medical students learn from textbooks and often struggle with the process of applying their conceptual knowledge to clinical problems. Recent studies address the question of how to foster the acquisition of procedural knowledge and its application in medical education. However, little is known about the factors which predict performance in procedural knowledge tasks. Which additional factors of the learner predict performance in procedural knowledge? Methods Domain specific conceptual knowledge (facts) in clinical nephrology was provided to 80 medical students (3rd to 5th year) using electronic flashcards in a laboratory setting. Learner characteristics were obtained by questionnaires. Procedural knowledge in clinical nephrology was assessed by key feature problems (KFP) and problem solving tasks (PST) reflecting strategic and conditional knowledge, respectively. Results Results in procedural knowledge tests (KFP and PST) correlated significantly with each other. In univariate analysis, performance in procedural knowledge (sum of KFP+PST) was significantly correlated with the results in (1) the conceptual knowledge test (CKT), (2) the intended future career as hospital based doctor, (3) the duration of clinical clerkships, and (4) the results in the written German National Medical Examination Part I on preclinical subjects (NME-I). After multiple regression analysis only clinical clerkship experience and NME-I performance remained independent influencing factors. Conclusions Performance in procedural knowledge tests seems independent from the degree of domain specific conceptual knowledge above a certain level. Procedural knowledge may be fostered by clinical experience. More attention should be paid to the interplay of individual clinical clerkship experiences and structured teaching of procedural knowledge and its assessment in medical education curricula.

Over the past several decades, the appearance of pink-pigmented bacteria in clinical specimens has gone from being a microbiologic curiosity in the clinical laboratory to the recognition of these aerobic microorganisms as etiologic agents of human disease, most notably bloodstream infections. Advances in the fields of molecular taxonomy and phylogenetics indicate that at least four distinct genera and eight different species are associated with clinical infections in susceptible patient populations. However, these bacteria are slow growing and present multiple diagnostic challenges to the microbiology laboratory including culture, isolation, and identification to species rank. This article provides a current review of these unusual non-fermentative chromogenic bacteria including their disease spectrum, taxonomy, and laboratory identification. The review also highlights the pitfalls or shortcomings we currently have in our knowledge of these microbes and their disease-producing capabilities.

Collaborations between neuroscience and music therapy promise many mutual benefits given the different knowledge bases, experiences and specialist skills possessed by each discipline. Primarily, music therapists deliver music-based interventions on a daily basis with numerous populations; neuroscientists measure clinical changes in ways that provide an evidence base for progressing clinical care. Although recent developments suggest that partnerships between the two can produce positive outcomes for both fields, these collaborations are not considered mainstream. The following dialog between an experienced professional from each discipline explores the potential for collaboration, as well as the misconceptions that may be preventing further synergies from developing.

OBJECTIVE Today's medical school graduates have significant deficits in physical examination skills. Medical educators have been searching for methods to effectively teach and maintain these skills in students. The objective of this study was to determine if an auscultation curriculum centered on a portable multimedia CD-ROM was effective in producing and maintaining significant gains in cardiac auscultatory skills. DESIGN Controlled cohort study PARTICIPANTS All 168 third-year medical students at 1 medical school in an academic medical center. INTERVENTIONS Students were tested before and after exposure to 1 or more elements of the auscultation curriculum: teaching on ward/clinic rotations, CD-ROM comprehensive cases with follow-up seminars, and a CD-ROM 20-case miniseries. The primary outcome measures were student performance on a 10-item test of auscultation skill (listening and identifying heart sound characteristics) and a 30-item test of auscultation knowledge (factual questions about auscultation). A subset of students was tested for attenuation effects 9 or 12 months after the intervention. RESULTS Compared with the control group (1 month clinical rotation alone), students who were also exposed to the CD-ROM 20-case miniseries had significant improvements in auscultation skills scores (P < .05), but not knowledge. Additional months of clerkship, comprehensive CD-ROM cases, and follow-up seminars increased auscultation knowledge beyond the miniseries alone (P < .05), but did not further improve auscultation skills. Students' auscultation knowledge diminished one year after the intervention, but auscultation skills did not. CONCLUSION In addition to the standard curriculum of ward and conference teaching, portable multimedia tools may help improve quality of physical examination skills. PMID:11722691

Two major views on the relationship between basic science knowledge and clinical knowledge stand out; the Two-world view seeing basic science and clinical science as two separate knowledge bases and the encapsulated knowledge view stating that basic science knowledge plays an overt role being encapsulated in the clinical knowledge. However, resent research has implied that a more complex relationship between the two knowledge bases exists. In this study, we explore the relationship between immediate relevant basic science (physiology) and clinical knowledge within a specific domain of medicine (echocardiography). Twenty eight medical students in their 3rd year and 45 physicians (15 interns, 15 cardiology residents and 15 cardiology consultants) took a multiple-choice test of physiology knowledge. The physicians also viewed images of a transthoracic echocardiography (TTE) examination and completed a checklist of possible pathologies found. A total score for each participant was calculated for the physiology test, and for all physicians also for the TTE checklist. Consultants scored significantly higher on the physiology test than did medical students and interns. A significant correlation between physiology test scores and TTE checklist scores was found for the cardiology residents only. Basic science knowledge of immediate relevance for daily clinical work expands with increased work experience within a specific domain. Consultants showed no relationship between physiology knowledge and TTE interpretation indicating that experts do not use basic science knowledge in routine daily practice, but knowledge of immediate relevance remains ready for use.

Medical knowledge is one of six core competencies in medicine. Medical student assessments should be valid and reliable. We assessed the relationship between faculty and resident global assessment of pediatric medical student knowledge and performance on a standardized test in medical knowledge. Retrospective cross-sectional study of medical students on a pediatric clerkship in academic year 2008-2009 at one academic health center. Faculty and residents rated students' clinical knowledge on a 5-point Likert scale. The inter-rater reliability of clinical knowledge ratings was assessed by calculating the intra-class correlation coefficient (ICC) for residents' ratings, faculty ratings, and both rating types combined. Convergent validity between clinical knowledge ratings and scores on the National Board of Medical Examiners (NBME) clinical subject examination in pediatrics was assessed with Pearson product moment correlation correction and the coefficient of the determination. There was moderate agreement for global clinical knowledge ratings by faculty and moderate agreement for ratings by residents. The agreement was also moderate when faculty and resident ratings were combined. Global ratings of clinical knowledge had high convergent validity with pediatric examination scores when students were rated by both residents and faculty. Our findings provide evidence for convergent validity of global assessment of medical students' clinical knowledge with NBME subject examination scores in pediatrics.

Isotope scanning using technetium 99m pertechnetate has fallen into disuse since the advent of x-ray computerized tomography. Regional brain blood flow studies have been pursued on a research basis. Increased regional blood flow during focal seizure activity has been demonstrated and is of use in localizing such foci. Cisternography as a predictive tool in normal pressure hydrocephalus is falling into disuse. Positron tomographic scanning is a potent research tool that can demonstrate both regional glycolysis and blood flow. Unfortunately, it is extremely expensive and complex to apply in a clinical setting. With support from the National Institutes of Health, sevenmore » extramural centers have been funded to develop positron tomographic capabilities, and they will greatly advance our knowledge of stroke pathophysiology, seizure disorders, brain tumors, and various degenerative diseases. Nuclear magnetic resonance imaging is a potentially valuable tool since it creates tomographic images representing the distribution of brain water. No tissue ionization is produced, and images comparable to second-generation computerized tomographic scans are already being produced in humans.« less
Ecto- and endoparasites of new world camelids.

2009-07-01
Parasitism in New World camelids (NWC), which is associated with both ecto- and endoparasites, is a major health concern throughout the world. Clinical disease has been noted as causing severe economic losses; subclinical issues have yet to be addressed. Despite the advances made in the knowledge and understanding of parasites of NWC, old parasites continue to plague producers, and new issues have arisen. This article updates information on the major ecto- and endoparasites of NWC, including diagnostic techniques and issues relative to anthelmintic resistance in nematodes.

Streptomycetes comprise very important industrial bacteria, producing two-thirds of all clinically relevant secondary metabolites. They are mycelial microorganisms with complex developmental cycles that include programmed cell death (PCD) and sporulation. Industrial fermentations are usually performed in liquid cultures (large bioreactors), conditions in which Streptomyces strains generally do not sporulate, and it was traditionally assumed that there was no differentiation. In this work, we review the current knowledge on Streptomyces pre-sporulation stages of Streptomyces differentiation. PMID:23496097

Clinical Bioinformatics is currently growing and is based on the integration of clinical and omics data aiming at the development of personalized medicine. Thus the introduction of novel technologies able to investigate the relationship among clinical states and biological machineries may help the development of this field. For instance the Affymetrix DMET platform (drug metabolism enzymes and transporters) is able to study the relationship among the variation of the genome of patients and drug metabolism, detecting SNPs (Single Nucleotide Polymorphism) on genes related to drug metabolism. This may allow for instance to find genetic variants in patients which present different drug responses, in pharmacogenomics and clinical studies. Despite this, there is currently a lack in the development of open-source algorithms and tools for the analysis of DMET data. Existing software tools for DMET data generally allow only the preprocessing of binary data (e.g. the DMET-Console provided by Affymetrix) and simple data analysis operations, but do not allow to test the association of the presence of SNPs with the response to drugs. We developed DMET-Analyzer a tool for the automatic association analysis among the variation of the patient genomes and the clinical conditions of patients, i.e. the different response to drugs. The proposed system allows: (i) to automatize the workflow of analysis of DMET-SNP data avoiding the use of multiple tools; (ii) the automatic annotation of DMET-SNP data and the search in existing databases of SNPs (e.g. dbSNP), (iii) the association of SNP with pathway through the search in PharmaGKB, a major knowledge base for pharmacogenomic studies. DMET-Analyzer has a simple graphical user interface that allows users (doctors/biologists) to upload and analyse DMET files produced by Affymetrix DMET-Console in an interactive way. The effectiveness and easy use of DMET Analyzer is demonstrated through different case studies regarding the analysis of clinical datasets produced in the University Hospital of Catanzaro, Italy. DMET Analyzer is a novel tool able to automatically analyse data produced by the DMET-platform in case-control association studies. Using such tool user may avoid wasting time in the manual execution of multiple statistical tests avoiding possible errors and reducing the amount of time needed for a whole experiment. Moreover annotations and the direct link to external databases may increase the biological knowledge extracted.

This paper will present an overview of the developmental effort in harmonizing clinical knowledge modeling using the Detailed Clinical Models (DCMs), and will explain how it can contribute to the preservation of Electronic Health Records (EHR) data. Clinical knowledge modeling is vital for the management and preservation of EHR and data. Such modeling provides common data elements and terminology binding with the intention of capturing and managing clinical information over time and location independent from technology. Any EHR data exchange without an agreed clinical knowledge modeling will potentially result in loss of information. Many attempts exist from the past to model clinical knowledge for the benefits of semantic interoperability using standardized data representation and common terminologies. The objective of each project is similar with respect to consistent representation of clinical data, using standardized terminologies, and an overall logical approach. However, the conceptual, logical, and the technical expressions are quite different in one clinical knowledge modeling approach versus another. There currently are synergies under the Clinical Information Modeling Initiative (CIMI) in order to create a harmonized reference model for clinical knowledge models. The goal for the CIMI is to create a reference model and formalisms based on for instance the DCM (ISO/TS 13972), among other work. A global repository of DCMs may potentially be established in the future.

The design and analysis of research may cause systematic gender dependent errors to be produced in results because of gender insensitivity or androcentrism. Gender bias in research could be defined as a systematically erroneous gender dependent approach related to social construct, which incorrectly regards women and men as similar/different. Most gender bias can be found in the context of discovery (development of hypotheses), but it has also been found in the context of justification (methodological process), which must be improved. In fact, one of the main effects of gender bias in research is partial or incorrect knowledge in the results, which are systematically different from the real values. This paper discusses some forms of conceptual and methodological bias that may affect women's health. It proposes a framework to analyse gender bias in the design and analysis of research carried out on women's and men's health problems, and on specific women's health issues. Using examples, the framework aims to show the different theoretical perspectives in a social or clinical research context where forms of selection, measurement and confounding bias are produced as a result of gender insensitivity. Finally, this paper underlines the importance of re‐examining results so that they may be reinterpreted to produce new gender based knowledge. PMID:18000118

Methods on developing new (de novo) clinical practice guidelines (CPGs) have received substantial attention. However, the volume of literature is not matched by research into alternative methods of CPG development using existing CPG documents-a specific issue for guideline development groups in low- and middle-income countries. We report on how we developed a context specific prehospital CPG using an alternative guideline development method. Difficulties experienced and lessons learnt in applying existing global guidelines' recommendations to a national context are highlighted. The project produced the first emergency care CPG for prehospital providers in Africa. It included > 270 CPGs and produced over 1000 recommendations for prehospital emergency care. We encountered various difficulties, including (1) applicability issues: few pre-hospital CPGs applicable to Africa, (2) evidence synthesis: heterogeneous levels of evidence classifications and (3) guideline quality. Learning points included (1) focusing on key CPGs and evidence mapping, (2) searching other resources for CPGs, (3) broad representation on CPG advisory boards and (4) transparency and knowledge translation. Re-inventing the wheel to produce CPGs is not always feasible. We hope this paper will encourage further projects to use existing CPGs in developing guidance to improve patient care in resource-limited settings.
‘A Most Protean Disease’: Aligning Medical Knowledge of Modern Influenza, 1890–1914
Bresalier, Michael
2012-01-01
This article reconstructs the process of defining influenza as an infectious disease in the contexts of British medicine between 1890 and 1914. It shows how professional agreement on its nature and identity involved aligning different forms of knowledge produced in the field (public health), in the clinic (metropolitan hospitals) and in the laboratory (bacteriology). Two factors were crucial to this process: increasing trust in bacteriology and the organisation of large-scale collective investigations into influenza by Britain’s central public authority, the Medical Department of the Local Government Board. These investigations integrated epidemiological, clinical and bacteriological evidence into a new definition of influenza as a specific infection, in which a germ – Bacillus influenzae – was determined as playing a necessary but not sufficient role in its aetiology, transmission and pathogenesis. In defining ‘modern influenza’, bacteriological concepts and techniques were adapted to and selectively incorporated into existing clinical, pathological and epidemiological approaches. Mutual alignment thus was crucial to its construction and, more generally, to shaping developing relationships between laboratory, clinical and public health medicine in turn-of-the-century Britain. While these relationships were marked by tension and conflict, they were also characterised by important patterns of convergence, in which the problems, interests and practices of public health professionals, clinicians and laboratory pathologists were made increasingly commensurable. Rather than retrospectively judge the late nineteenth-century definition of influenza as being based on the wrong microbe, this article argues for the need to examine how it was established through a particular alignment of medical knowledge, which then underpinned medical approaches to the disease up to and beyond the devastating 1918–19 pandemic.

A compromised oral health condition amongst patients with special health care needs (SHCN) has been associated with the reluctance and shortage of skills of dental professionals in managing such patients. Lack of training and experience at the undergraduate level are reported barriers to the provision of care for this patient cohort. Undergraduate education therefore, plays an important role in producing professionals with the knowledge, skills and positive attitude in treating patients with SHCN. This study aims to determine the level of knowledge, comfort and attitudes of Malaysian undergraduate dental students towards caring for patients with SHCN, as well as their perception on education in this field. A self-administered questionnaire was administered in the classroom style to final year undergraduate dental students in Malaysian public dental schools. Most students were aware of Special Needs Dentistry (SND) as a specialty after being informed by academic staff. The majority of the students demonstrated poor knowledge in defining SND and felt uncomfortable providing care for such patients. They perceived their undergraduate training in SND as inadequate with most students agreeing that they should receive didactic and clinical training at undergraduate level. A high percentage of students also expressed interest in pursuing postgraduate education in this area of dentistry despite the lack of educational exposure during undergraduate years. The study supports a need for educational reform to formulate a curriculum that is more patient-centred, with earlier clinical exposure in various clinical settings for students to treat patients with special health care needs, applying the concept of holistic care in a variable clinical condition. © 2014 John Wiley & Sons A/S.

Objectives Androgens are essential for the development and growth of the penis, and they regulate erectile physiology by multiple mechanisms. Our goal is to provide a concise overview of the basic research and how this knowledge can be translated into a new clinical paradigm for patient management. In addition, this new paradigm may serve as a basis for stimulating constructive debate regarding the use of testosterone in men, and to promote new, innovative basic and clinical research to further understand the underlying mechanisms of androgen action in restoring erectile physiology. Methods A literature review was performed utilizing the US National Library of Medicine's PubMed database. Results On the basis of evidence derived from laboratory animal studies and clinical data, we postulate that androgen insufficiency disrupts cellular-signaling pathways and produces pathologic alterations in penile tissues, leading to erectile dysfunction. In this review, we discuss androgen-dependent cellular, molecular, and physiologic mechanisms modulating erectile function in the animal model, and the implication of this knowledge in testosterone use in the clinical setting to treat erectile dysfunction. The new clinical paradigm incorporates many of the consensed points of view discussed in traditional consensed algorithms exclusively designed for men with androgen insufficiency. There are, however, novel and innovative differences with this new clinical paradigm. This paradigm represents a fresh effort to provide mandatory and optional management strategies for men with both androgen insufficiency and erectile dysfunction. Conclusions The new clinical paradigm is evidence-based and represents one of the first attempts to address a logical management plan for men with concomitant hormonal and sexual health concerns.

This study systematically examined how experienced Speech-Language Pathologists (SLPs) use the processes of reflection to develop knowledge relevant for practice in the context of head and neck cancer (HNC) rehabilitation. In-depth, semi-structured interviews were conducted with 12 SLPs working in HNC rehabilitation in North America. Grounded theory methodology was adopted for data collection and analysis. The findings inform a preliminary reflective practice model that depicts the processes of reflection used by practitioners interviewed. Nine categories of reflective processes were identified by participant SLPs in terms of the processes of reflection: ongoing questioning, experimenting through trial and error, integrating knowledge from past cases, embracing surprise, thinking out of the box, being in the moment, consulting with colleagues, putting oneself in the patients' shoes, and discerning ethical issues. These findings provide empirical evidence that supports Schön's theory of reflective practice and contribute to knowledge about the ways in which SLPs use processes of reflection in the context of HNC rehabilitation. The findings of this study have implications for how SLPs perceive and consider their role as knowledge-users and knowledge producers in their day-to-day clinical work, as well as for building capacity for reflective practice.

Patients' knowledge about oral anticoagulant therapy may favor the achievement of therapeutic results and the prevention of adverse pharmacotherapy-related events. Brazil lacks validated instruments for assessing the patient's knowledge about treatment with warfarin. This study aimed to perform the cross-cultural adaptation of the Oral Anticoagulation Knowledge (OAK) Test instrument from English into Portuguese. This is a methodological study developed in an anticoagulation clinic of a public university hospital. The study included initial translation, synthesis of translations, back-translation, review by the experts committee and pre-testing with 30 individuals. We obtained semantic equivalence through the analysis of the referential and general meaning of each item. The conceptual equivalence of the items sought to demonstrate the relevance and acceptability of the instrument. The process of cross-cultural adaptation produced the final version of the OAK Test in Brazilian Portuguese entitled "Teste de Conhecimento sobre Anticoagulação Oral". There was a suitable semantic and conceptual equivalence between the adapted version and the original version, as well as an excellent acceptability of this instrument.

Intensity modulated radiation therapy (IMRT) is widely used to achieve a highly conformal dose and improve treatment outcome. However, plan quality and planning time are institute and planner dependent, and no standardized tool exists to recognize an optimal plan. RapidPlan, a knowledge-based algorithm, can generate constraints to assist optimization and produce high-quality IMRT plans. This report evaluated the quality and efficiency of using RapidPlan in nasopharyngeal carcinoma (NPC) IMRT planning. RapidPlan was configured using 79 radical IMRT plans for NPC; 20 consecutive NPC patients indicated for radical radiation therapy between October 2014 and May 2015 were then recruited to assess its performance. The ability of RapidPlan to produce acceptable plans was evaluated. For plans that could not achieve clinical acceptance, manual touch-up was performed. The IMRT plans produced without RapidPlan (manual plans) and with RapidPlan (RP-2 plans, including those with manual touch-up) were compared in terms of dosimetric quality and planning efficiency. RapidPlan by itself could produce clinically acceptable plans for 9 of the 20 patients; manual touch-up increased the number of acceptable plans (RP-2 plans) to 19. The target dose coverage and conformity were very similar. No difference was found in the maximum dose to the brainstem and optic chiasm. RP-2 plans delivered a higher maximum dose to the spinal cord (46.4 Gy vs 43.9 Gy, P=.002) but a lower dose to the parotid (mean dose to right parotid, 37.3 Gy vs 45.4 Gy; left, 34.4 Gy vs 43.1 Gy; P<.001) and the right cochlea (mean dose, 48.6 Gy vs 52.6 Gy; P=.02). The total planning time for RP-2 plans was significantly less than that for manual plans (64 minutes vs 295 minutes, P<.001). This study shows that RapidPlan can significantly improve planning efficiency and produce quality IMRT plans for NPC patients. Copyright © 2016 Elsevier Inc. All rights reserved.

This handbook is intended to be an accessible, easy-to-consult guide to help professionals produce or adapt Evidence-Based Documents. Such documents will help standardize both clinical practice and decision-making, the quality always being monitored in such a way that established references are complied with. Evidence-Based Health Care Committee, a member of "Virgen del Rocío" University Hospital quality structure, proposed the preparation of a handbook to produce Evidence-Based Documents including: a description of products, characteristics, qualities, uses, methodology of production, and application scope of every one of them. The handbook consists of seven Evidence-Based tools, one chapter on critical analysis methodology of scientific literature, one chapter with internet resources, and some appendices with different assessment tools. This Handbook provides general practitioners with a great opportunity to improve quality and as a guideline to standardize clinical healthcare, and managers with a strategy to promote and encourage the development of documents in an effort to reduce clinical practice variability, as well as giving patients the opportunity of taking part in planning their own care.

Education in the workplace for the physician: clinical management states as an organizing framework.
Greenes, R A
2000-01-01
Medical educators are interested in approaches to making selected relevant knowledge available in the context of problem-based care. This is of value both during the process of care and as a means of organizing information for offline self-study. Four trends in health information technology are relevant to achieving the goal and can be expected to play a growing role in the future. First, health care enterprises are developing approaches for access to information resources related to the care of a patient, including clinical data and images but also communication tools, referral and other logistic tools, decision support, and educational materials. Second, information for patients and methods for patient-doctor interaction and decision making are becoming available. Third, computer-based methods for representation of practice guidelines are being developed to support applications that can incorporate their logic. Finally, considering patients as being in particular "clinical management states" (or CMSs) for specific problems, approaches are being developed to use guidelines as a kind of "predictive" framework to enable development of interfaces for problem-based clinical encounters. The guidelines for a CMS can be used to identify the kinds of resources specifically needed for clinical encounters of that type. As the above trends converge to produce problem-specific environments, professional specialty organizations and continuing medical education course designers will need to focus energies on organizing and updating medical knowledge to make it available in CMS-specific contexts.

There is growing evidence in the UK that some National Health Service improvements, particularly in the postnatal period, are having an impact on the quality and variety of student midwives' clinical experiences, making it challenging for them to meet the standards set by the regulatory body for midwives and receive a licence to practice. A possible solution to this may be the introduction of a Student Midwife integrated Learning Environment (SMiLE) focusing upon the delivery of postnatal care (PN) through a student run clinic. To identify the current state of knowledge, regarding the educational outcomes of students who engage with student run clinics (SRC) and the satisfaction of clients who attend them. Search strategy--BNI, CINAHL, EMBASE, and MEDLINE were searched for articles published until April 2014. Studies, nationally and internationally, were carried out on healthcare students running their own clinics. Outcome measures were the evaluation of educational outcomes of students and client satisfaction were included. Data were extracted, analysed and synthesised to produce a summary of knowledge, regarding the effectiveness of SRCs. 6 studies were selected for this review. The findings that SRC can offer advantages in improving educational outcomes of students and provide an effective service to clients are encouraging. However, given the limited number of high-quality studies included in this review, further research is required to investigate the effectiveness of SRC. Copyright © 2014 Elsevier Ltd.

In order to expand the present knowledge of the pathogenic potential of Blastoschizomyces capitatus in central venous catheter (CVC)-related bloodstream infections, six strains of the organism recovered from three leukemic patients with CVC-related fungemia in different years were investigated. Isolates and control strains were tested for their genetic relatedness and for their ability to produce slime in glucose-containing solutions. DNA restriction enzyme analysis revealed that all strains of B. capitatus were identical, whereas slime production assays and examination of ex vivo material showed that they were able to produce large amounts of slime. Slime production may therefore play a relevant pathogenic role in cases of CVC-related fungemia caused by B. capitatus.

Clinical guidelines have been shown to improve the quality of medical care and to reduce its costs. However, most guidelines exist in a free-text representation and, without automation, are not sufficiently accessible to clinicians at the point of care. A prerequisite for automated guideline application is a machine-comprehensible representation of the guidelines. In this study, we designed and implemented a scalable architecture to support medical experts and knowledge engineers in specifying and maintaining the procedural and declarative aspects of clinical guideline knowledge, resulting in a machine comprehensible representation. The new framework significantly extends our previous work on the Digital electronic Guidelines Library (DeGeL) The current study designed and implemented a graphical framework for specification of declarative and procedural clinical knowledge, Gesher. We performed three different experiments to evaluate the functionality and usability of the major aspects of the new framework: Specification of procedural clinical knowledge, specification of declarative clinical knowledge, and exploration of a given clinical guideline. The subjects included clinicians and knowledge engineers (overall, 27 participants). The evaluations indicated high levels of completeness and correctness of the guideline specification process by both the clinicians and the knowledge engineers, although the best results, in the case of declarative-knowledge specification, were achieved by teams including a clinician and a knowledge engineer. The usability scores were high as well, although the clinicians' assessment was significantly lower than the assessment of the knowledge engineers.

Dementia is a clinical syndrome characterized by progressive degeneration in cognitive ability that limits the capacity for independent living. Interventions are needed to target the medical, social, psychological, and knowledge needs of caregivers and patients. This study used a mixed methods approach to evaluate the effectiveness of a dementia novela presented in an audio-visual format in improving dementia attitudes, beliefs and knowledge. Adults from Los Angeles (N = 42, 83% female, 90% Hispanic/Latino, mean age = 42.2 years, 41.5% with less than a high school education) viewed an audio-visual novela on dementia. Participants completed surveys immediately before and after viewing the material. The novela produced significant improvements in overall knowledge (t(41) = -9.79, p < .0001) and led to positive increases in specific attitudes toward people with dementia but not in beliefs that screening would be beneficial. Qualitative results provided concordant and discordant evidence for the quantitative findings. Results indicate that an audio-visual novela can be useful for improving attitudes and knowledge about dementia, but further work is needed to investigate the relation with health disparities in screening and treatment behaviors. Audio visual novelas are an innovative format for health education and change attitudes and knowledge about dementia.

It is becoming increasingly necessary, in France, to develop a more efficient public health policy and define research in terms of the perspective of its use for public decisions and clinical practice. One possible solution consists of knowledge transfer and sharing based on a continuous exchange and interaction process between scientists and potential users of research data - field workers and health policy decision-makers. Such a process would involve collaboration with users to help them apply the evidence produced by research as well as the mobilization of research scientists to develop research more adapted to needs. This article defines the goals of development of knowledge transfer in the French setting. The conceptual bases are defined and four strategic axes and their operational modalities are developed. This proposal also integrates all of the public authorities concerned: promote knowledge transfer; reinforce observation and diffusion of evidence and its usability; promote the development of more adapted public health research by facilitating research scientist /research data user relationships; assist the various parties in the exchange and sharing of knowledge. Apart from improving the efficiency of health policies, the development of knowledge transfer and sharing would also strengthen the credibility of certain intervention strategies, especially in the field of prevention, by designing evidence-based strategies.
Rethinking production of Taxol® (paclitaxel) using endophyte biotechnology.
Kusari, Souvik; Singh, Satpal; Jayabaskaran, Chelliah
2014-06-01
Taxol® (generic name paclitaxel) represents one of the most clinically valuable natural products known to mankind in the recent past. More than two decades have elapsed since the notable discovery of the first Taxol®-producing endophytic fungus, which was followed by a plethora of reports on other endophytes possessing similar biosynthetic potential. However, industrial-scale Taxol® production using fungal endophytes, although seemingly promising, has not seen the light of the day. In this opinion article, we embark on the current state of knowledge on Taxol® biosynthesis focusing on the chemical ecology of its producers, and ask whether it is actually possible to produce Taxol® using endophyte biotechnology. The key problems that have prevented the exploitation of potent endophytic fungi by industrial bioprocesses for sustained production of Taxol® are discussed. Copyright © 2014 Elsevier Ltd.

Social work and the Uniform Accident and Sickness Policy Provision Law: a pilot project.
Cochran, Gerald; Davis, King
2012-01-01
The Uniform Accident and Sickness Policy Provision Law (UPPL) is a statute existing in 26 states that permits health insurance companies to deny payment for claims made by individuals who have sustained injuries as a result of drug or alcohol use. This law presents a series of complicated clinical and ethical dilemmas for social workers and other medical personnel. The majority of contributions to the national discussion regarding the UPPL have been produced by the medical, nursing, and policy/legal disciplines. Social work has, however, remained silent. It is paramount that social workers add their perspective and insight to this debate. This article discusses the first survey, to the authors' knowledge, of social workers practicing in health care settings regarding their knowledge and beliefs about the UPPL.
Basic Sciences Fertilizing Clinical Microbiology and Infection Management
2017-01-01
Abstract Basic sciences constitute the most abundant sources of creativity and innovation, as they are based on the passion of knowing. Basic knowledge, in close and fertile contact with medical and public health needs, produces distinct advancements in applied sciences. Basic sciences play the role of stem cells, providing material and semantics to construct differentiated tissues and organisms and enabling specialized functions and applications. However, eventually processes of “practice deconstruction” might reveal basic questions, as in de-differentiation of tissue cells. Basic sciences, microbiology, infectious diseases, and public health constitute an epistemological gradient that should also be an investigational continuum. The coexistence of all these interests and their cross-fertilization should be favored by interdisciplinary, integrative research organizations working simultaneously in the analytical and synthetic dimensions of scientific knowledge.

SU-E-P-43: A Knowledge Based Approach to Guidelines for Software Safety
DOE Office of Scientific and Technical Information (OSTI.GOV)
Salomons, G; Kelly, D
Purpose: In the fall of 2012, a survey was distributed to medical physicists across Canada. The survey asked the respondents to comment on various aspects of software development and use in their clinic. The survey revealed that most centers employ locally produced (in-house) software of some kind. The respondents also indicated an interest in having software guidelines, but cautioned that the realities of cancer clinics include variations, that preclude a simple solution. Traditional guidelines typically involve periodically repeating a set of prescribed tests with defined tolerance limits. However, applying a similar formula to software is problematic since it assumes thatmore » the users have a perfect knowledge of how and when to apply the software and that if the software operates correctly under one set of conditions it will operate correctly under all conditions Methods: In the approach presented here the personnel involved with the software are included as an integral part of the system. Activities performed to improve the safety of the software are done with both software and people in mind. A learning oriented approach is taken, following the premise that the best approach to safety is increasing the understanding of those associated with the use or development of the software. Results: The software guidance document is organized by areas of knowledge related to use and development of software. The categories include: knowledge of the underlying algorithm and its limitations; knowledge of the operation of the software, such as input values, parameters, error messages, and interpretation of output; and knowledge of the environment for the software including both data and users. Conclusion: We propose a new approach to developing guidelines which is based on acquiring knowledge-rather than performing tests. The ultimate goal is to provide robust software guidelines which will be practical and effective.« less

Objectives. We carried out an independent short-term impact evaluation of a social marketing campaign designed to reduce syphilis infections among men who have sex with men in south Florida in 2004. Methods. Venue-based surveys were conducted shortly after the campaign began and 6 months later to assess changes in exposure to campaign materials, awareness, knowledge about syphilis, perceptions of risk, sexual behavior, clinic visits, and testing and treatment for syphilis among participants. Results. Exposure to social marketing campaign materials increased from 18.0% at baseline to 36.5% at follow-up (P< .001). Awareness of syphilis and perceptions of risk increased among Broward County residents but not among Miami–Dade County residents. Risky sexual practices and patterns of recreational drug use did not change. No significant increases in knowledge, clinic visits, or testing or treatment for syphilis among participants were detected over the 6-month study period. Conclusions. None of the campaign objectives were fully met. The interventions were insufficient to produce a significant impact among men who have sex with men in south Florida. PMID:18172146

To identify the information needs of children with nocturnal enuresis, and to design, produce and evaluate an interactive computer program to provide this information. The program was developed over an 18-month period using information provided by children, parents and professionals, and was evaluated in a hospital-based enuresis clinic in 65 children. Usability and knowledge gained were also evaluated in 43 healthy children aged 8-10 years attending a local inner-city primary school. An interactive program about nocturnal enuresis was developed, which runs on a personal computer and uses sound, voice, cartoon drawings and animation in a modular design. Knowledge scores increased in clinic attendees and in schoolchildren after using the program (Wilcoxon matched pairs test, P < 0.001). This improvement was maintained when the program was re-tested 6-10 months later. This interactive computer program holds children's attention and increases their understanding of enuresis. Interactive multimedia may be useful to complement the information provided by health professionals. This method of communication may be particularly useful for children with a low level of literacy.

The concern of academics and clinicians about the alleged dichotomy between theoretical concepts and the practice of nursing has been the catalyst for the development of a pocket-sized aid for nurses, known as the Knowledge Underpinning Practice Orientation Dial (KUPOD [N]/The Dial). A mixed method approach was used incorporating a questionnaire and a focus group of educators. The Dial was introduced, as part of a module, undertaken by a cohort of second-year Diploma in Nursing (Adult Branch) students. Twenty-eight students returned the questionnaire (response rate=85%). Results revealed that the Dial was easy to use in a variety of situations and locations. Respondents used the Dial within clinical and classroom settings and for self directed study. They reported that it was a practical and effective aid to learning, assisting in correlating theory and practice. It supported reflection and enhanced confidence in the clinical area, indicating that this economically produced tool helps to bridge the theory-practice gap. The Dial is now being introduced as a learning resource to a wider range of students.

Knowledge of the genetic changes that lead to disease has grown and continues to grow at a rapid pace. However, there is a need for clinical devices that can be used routinely to translate this knowledge into the treatment of patients. Use in a clinical setting requires high sensitivity and specificity (>97%) in order to prevent misdiagnoses. Single strand conformational polymorphism (SSCP) and heteroduplex analysis (HA) are two DNA-based, complementary methods for mutation detection that are inexpensive and relatively easy to implement. However, both methods are most commonly detected by slab gel electrophoresis, which can be labor-intensive, time-consuming, and often the methods are unable to produce high sensitivity and specificity without the use of multiple analysis conditions. Here we demonstrate the first blinded study using microchip electrophoresis-SSCP/HA. We demonstrate the ability of microchip electrophoresis-SSCP/HA to detect with 98% sensitivity and specificity >100 samples from the p53 gene exons 5–9 in a blinded study in an analysis time of less than 10 minutes.

We carried out an independent short-term impact evaluation of a social marketing campaign designed to reduce syphilis infections among men who have sex with men in south Florida in 2004. Venue-based surveys were conducted shortly after the campaign began and 6 months later to assess changes in exposure to campaign materials, awareness, knowledge about syphilis, perceptions of risk, sexual behavior, clinic visits, and testing and treatment for syphilis among participants. Exposure to social marketing campaign materials increased from 18.0% at baseline to 36.5% at follow-up (P< .001). Awareness of syphilis and perceptions of risk increased among Broward County residents but not among Miami-Dade County residents. Risky sexual practices and patterns of recreational drug use did not change. No significant increases in knowledge, clinic visits, or testing or treatment for syphilis among participants were detected over the 6-month study period. None of the campaign objectives were fully met. The interventions were insufficient to produce a significant impact among men who have sex with men in south Florida.

An electronic health record (EHR) can assist the delivery of high-quality patient care, in part by providing the capability for a broad range of clinical decision support, including contextual references (e.g., Infobuttons), alerts and reminders, order sets, and dashboards. All of these decision support tools are based on clinical knowledge; unfortunately, the mechanisms for managing rules, order sets, Infobuttons, and dashboards are often unrelated, making it difficult to coordinate the application of clinical knowledge to various components of the clinical workflow. Additional complexity is encountered when updating enterprise-wide knowledge bases and delivering the content through multiple modalities to different consumers. We present the experience of Mayo Clinic as a case study to examine the requirements and implementation challenges related to knowledge management across a large, multi-site medical center. The lessons learned through the development of our knowledge management and delivery platform will help inform the future development of interoperable knowledge resources.

Knowledge Acquisition of Generic Queries for Information Retrieval
Seol, Yoon-Ho; Johnson, Stephen B.; Cimino, James J.
2002-01-01
Several studies have identified clinical questions posed by health care professionals to understand the nature of information needs during clinical practice. To support access to digital information sources, it is necessary to integrate the information needs with a computer system. We have developed a conceptual guidance approach in information retrieval, based on a knowledge base that contains the patterns of information needs. The knowledge base uses a formal representation of clinical questions based on the UMLS knowledge sources, called the Generic Query model. To improve the coverage of the knowledge base, we investigated a method for extracting plausible clinical questions from the medical literature. This poster presents the Generic Query model, shows how it is used to represent the patterns of clinical questions, and describes the framework used to extract knowledge from the medical literature.

This paper is a report of the development and testing of a questionnaire measuring knowledge and skills of cancer clinical trials nurse in Australia. The role of cancer clinical trials nurse, widely acknowledged as an integral member of the clinical research team, has evolved in recent years. Elements of the clinical trials nurse role in cancer have previously been described. To evaluate specific cancer clinical trials nurse educational and training needs, the development of a valid and reliable tool is required. In 2009, a study was conducted in three stages. Stage I: questionnaire development and pilot testing; stage II: focus group; stage III: national survey. Internal consistency reliability testing and multi-trait analysis of item convergent/divergent validity were employed. Regression analysis was used to identify predictors of clinical trials nurse knowledge and skills. The national survey was a 48-item questionnaire, measuring six clinical trial knowledge and seven skills sub-scales. Of 61 respondents, 90% were women, with mean age 43 years, 19 years as a Registered Nurse and 5 years as a cancer clinical trials nurse. Self-reported knowledge and skills were satisfactory to good. Internal consistency reliability was high (Cronbach's alpha: knowledge = 0·98; skills = 0·90). Criteria for item convergent/divergent validity were met. Number of years as cancer clinical trials nurse was positively related to self-reported knowledge and skills. Preliminary data suggest that the national survey is reliable and valid. Data have contributed to better understanding the knowledge and skills of cancer clinical trials nurse in Australia and development of a postgraduate course in clinical trials. © 2011 Blackwell Publishing Ltd.

Focused ultrasonic propulsion is a new noninvasive technique designed to move kidney stones and stone fragments out of the urinary collecting system. However, to our knowledge the extent of tissue injury associated with this technique is not known. We quantitated the amount of tissue injury produced by focused ultrasonic propulsion under simulated clinical treatment conditions and under conditions of higher power or continuous duty cycles. We compared those results to extracorporeal shock wave lithotripsy injury. A human calcium oxalate monohydrate stone and/or nickel beads were implanted by ureteroscopy in 3 kidneys of live pigs weighing 45 to 55 kg and repositioned using focused ultrasonic propulsion. Additional pig kidneys were exposed to extracorporeal shock wave lithotripsy level pulse intensity or continuous ultrasound exposure 10 minutes in duration using an ultrasound probe transcutaneously or on the kidney. These kidneys were compared to 6 treated with an unmodified Dornier HM3 lithotripter (Dornier Medical Systems, Kennesaw, Georgia) using 2,400 shocks at 120 shock waves per minute and 24 kV. Histological analysis was performed to assess the volume of hemorrhagic tissue injury created by each technique according to the percent of functional renal volume. Extracorporeal shock wave lithotripsy produced a mean ± SEM lesion of 1.56% ± 0.45% of functional renal volume. Ultrasonic propulsion produced no detectable lesion with simulated clinical treatment. A lesion of 0.46% ± 0.37% or 1.15% ± 0.49% of functional renal volume was produced when excessive treatment parameters were used with the ultrasound probe placed on the kidney. Focused ultrasonic propulsion produced no detectable morphological injury to the renal parenchyma when using clinical treatment parameters but produced injury comparable in size to that of extracorporeal shock wave lithotripsy when using excessive treatment parameters.

Informatics in neurocritical care: new ideas for Big Data.
Flechet, Marine; Grandas, Fabian Güiza; Meyfroidt, Geert
2016-04-01
Big data is the new hype in business and healthcare. Data storage and processing has become cheap, fast, and easy. Business analysts and scientists are trying to design methods to mine these data for hidden knowledge. Neurocritical care is a field that typically produces large amounts of patient-related data, and these data are increasingly being digitized and stored. This review will try to look beyond the hype, and focus on possible applications in neurointensive care amenable to Big Data research that can potentially improve patient care. The first challenge in Big Data research will be the development of large, multicenter, and high-quality databases. These databases could be used to further investigate recent findings from mathematical models, developed in smaller datasets. Randomized clinical trials and Big Data research are complementary. Big Data research might be used to identify subgroups of patients that could benefit most from a certain intervention, or can be an alternative in areas where randomized clinical trials are not possible. The processing and the analysis of the large amount of patient-related information stored in clinical databases is beyond normal human cognitive ability. Big Data research applications have the potential to discover new medical knowledge, and improve care in the neurointensive care unit.

B cells have been generally considered to be positive regulators of immune responses because of their ability to produce antigen-specific antibodies and to activate T cells through antigen presentation. Impairment of B cell development and function may cause inflammatory and autoimmune diseases. Recently, specific B cell subsets that can negatively regulate immune responses have been described in mouse models of a wide variety of inflammatory and autoimmune diseases. The concept of those B cells, termed regulatory B cells, is now recognized as important in the murine immune system. Among several regulatory B cell subsets, IL-10-producing regulatory B cells are the most widely investigated. On the basis of discoveries from studies of such mice, human regulatory B cells that produce IL-10 in most cases are becoming an active area of research. There have been emerging data suggesting the importance of human regulatory B cells in various diseases. Revealing the immune regulation mechanisms of human regulatory B cells in human inflammatory and autoimmune diseases could lead to the development of novel B cell targeted therapies. This review highlights the current knowledge on regulatory B cells, mainly IL-10-producing regulatory B cells, in animal models of inflammatory and autoimmune diseases and in clinical research using human samples. © The Japanese Society for Immunology. 2015.

Danish research-active clinical nurses overcome barriers in research utilization.
Adamsen, Lis; Larsen, Kristian; Bjerregaard, Lene; Madsen, Jan K
2003-03-01
The aim of this study was to examine whether there was a difference between clinical nurses who were research-active, and clinical nurses who were nonresearch-active in utilization of research. A further aim was to identify the most significant barriers faced by a group of Danish clinical nurses in their use of research. Discrepancy between the improved quality of research results and the lack of implementing them was the starting point for a series of studies which showed the types of barriers clinical nurses found especially cumbersome when applying the research results of other researchers. This study investigates whether the clinical nurses' own engagement in research had any impact on their perception of research utilization. The study had an exploratory and descriptive design. Seventy-nine Danish clinical nurses participated and semi-structured interviewing was used as the research method. There was a statistically significant difference between the research-active and nonresearch-active nurses on various variables. The study showed that, to a larger extent, research-active nurses used evidence-based knowledge and were generally more internationally orientated. Furthermore, two important barriers for research utilization were identified by all 79 clinical nurses included in the study, i.e. 90% of the nurses explained that the quantity of research results was overwhelming, and 75% of them found that they were unable to evaluate the quality of the research. Clinical nurses, who were research-active themselves, experienced more success in overcoming some of the barriers, which existed in applying research to practice. The research potential found amongst clinical nurses in Denmark needed to be further supported through training and guidance in research methodology, establishing introductory stipends and part-time research positions. By doing so, some of the barriers affecting research utilization and the so-called theory-practice gap might be reduced. Further empirical studies, based on Giddens theory of sociological reflectivity, might see clinical nurses in a more serious light and simultaneously perceive them as producers of knowledge.
Theory as metaphor: clinical knowledge and its communication.
Colman, Warren
2009-04-01
This paper investigates the relationship between clinical knowledge and psychological theory and considers the implications for clinical writing. I argue that clinical knowledge is a way of understanding rather than a body of facts and compare clinical material to 'texts' that generate multiple and indeterminate meanings. Analytic theories, which represent the crystallization of ways of understanding clinical phenomena, have an inherently metaphorical 'as if' quality since they are derived from and adapted to the clinical process of making meaning by representing psychic states in symbolic form. Thus good clinical writing demonstrates an integration of theory and clinical material into a unified network of symbolic meanings. Redfearn's paper, 'The captive, the treasure, the hero and the "anal" stage of development' (1979), is discussed as an exemplar of such integration. It is suggested that clinical knowledge is equivalent to the skill of making effective interpretations.

Food insecurity is associated with poor health outcomes, yet is not routinely addressed in health care. This study was conducted to determine if education regarding food insecurity as a health issue could modify knowledge, attitudes, and clinical behavior. Educational sessions on food insecurity and its impact on health were conducted in 2015 at three different family medicine residency programs and one medical school. A pre/post survey was given immediately before and after this session. Attendees were encouraged to identify and implement individual and system-based changes to integrate food insecurity screening and referrals into their clinical practices. Participants completed follow-up surveys approximately 1 year later, and the authors obtained systems-level data from electronic health records and databases. Pre/post means (SD) were compared using t-tests. The numbers of patients screened and referred were calculated. Eighty-five participants completed the pre/post survey during the educational sessions (51 medical students, 29 residents, 5 faculty). Self-reported knowledge of food insecurity, resources, and willingness to discuss with patients increased (P<0.0001 for all). Each program identified a feasible systems-based change. Follow-up surveys demonstrated increased discussion of food insecurity during clinical visits and referrals to food resources. Over 1,600 patients were screened for food insecurity as a result of systems-based changes. Educational interventions focused on the role of food insecurity in health can produce improvements in knowledge and attitudes toward addressing food insecurity, increase discussions with patients about food insecurity, and result in measurable patient and systems-level changes.

(1) To determine the impact of a digital educational intervention on the knowledge, attitudes, confidence and behavioural intention of registered children's nurses working with children and young people (CYP) admitted with self-harm.(2) To explore the perceived impact, suitability and usefulness of the intervention. A digital educational intervention that had been co-produced with CYP service users, registered children's nurses and academics. A prospective, uncontrolled, intervention study with preintervention and postintervention measurement, conducted at a large acute NHS Trust in the UK. From a pool of 251 registered children's nurses and 98 participants were recruited to complete the intervention (response rate=39%). At follow-up, 52% of participants completed the postintervention questionnaire, with 65% (n=33) of those reporting to have completed the digital educational intervention. Attitude towards self-harm in CYP was measured using a 13-item questionnaire; knowledge of self-harm in CYP was measured through an adapted 12-item questionnaire; confidence in different areas of practice was measured through Likert Scale responses; self-efficacy for working with CYP who have self-harmed was measured through an adapted version of the Self-efficacy Towards Helping Scale; clinical behavioural intention was measured by the Continuing Professional Development Reaction Questionnaire. Semistructured interviews were undertaken with a purposive sample of participants. For those who completed the intervention (n=33), improvements were observed in knowledge (effect size, ES: 0.69), confidence, and in some domains relating to attitudes (effectiveness domain-ES: 0.49), and clinical behavioural intention (belief about consequences-ES:0.49; moral norm-ES: 0.43; beliefs about capability-ES: 0.42). Qualitative findings suggest participants experienced skill development, feelings of empowerment and reflection on own practice. The effect of the intervention is promising and demonstrates the potential it has in improving registered children's nurse's knowledge, confidence and attitudes. However, further testing is required to confirm this. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

Clinical management of comorbidities is a challenge, especially in a clinical decision support setting, as it requires the safe and efficient reconciliation of multiple disease-specific clinical procedures to formulate a comorbid therapeutic plan that is both effective and safe for the patient. In this paper we pursue the integration of multiple disease-specific Clinical Practice Guidelines (CPG) in order to manage co-morbidities within a computerized Clinical Decision Support System (CDSS). We present a CPG integration framework-termed as COMET (Comorbidity Ontological Modeling & ExecuTion) that manifests a knowledge management approach to model, computerize and integrate multiple CPG to yield a comorbid CPG knowledge model that upon execution can provide evidence-based recommendations for handling comorbid patients. COMET exploits semantic web technologies to achieve (a) CPG knowledge synthesis to translate a paper-based CPG to disease-specific clinical pathways (CP) that include specialized co-morbidity management procedures based on input from domain experts; (b) CPG knowledge modeling to computerize the disease-specific CP using a Comorbidity CPG ontology; (c) CPG knowledge integration by aligning multiple ontologically-modeled CP to develop a unified comorbid CPG knowledge model; and (e) CPG knowledge execution using reasoning engines to derive CPG-mediated recommendations for managing patients with comorbidities. We present a web-accessible COMET CDSS that provides family physicians with CPG-mediated comorbidity decision support to manage Atrial Fibrillation and Chronic Heart Failure. We present our qualitative and quantitative analysis of the knowledge content and usability of COMET CDSS.
Estimating Return on Investment in Translational Research: Methods and Protocols
Trochim, William; Dilts, David M.; Kirk, Rosalind
2014-01-01
Assessing the value of clinical and translational research funding on accelerating the translation of scientific knowledge is a fundamental issue faced by the National Institutes of Health and its Clinical and Translational Awards (CTSA). To address this issue, the authors propose a model for measuring the return on investment (ROI) of one key CTSA program, the clinical research unit (CRU). By estimating the economic and social inputs and outputs of this program, this model produces multiple levels of ROI: investigator, program and institutional estimates. A methodology, or evaluation protocol, is proposed to assess the value of this CTSA function, with specific objectives, methods, descriptions of the data to be collected, and how data are to be filtered, analyzed, and evaluated. This paper provides an approach CTSAs could use to assess the economic and social returns on NIH and institutional investments in these critical activities. PMID:23925706

Helminthic parasites and seizures.
Garcia, Hector H; Modi, Manish
2008-08-01
A large number of helminthic parasites are known to involve the central nervous system (CNS) and produce neurologic symptoms including seizures and epilepsy. Taenia solium (the pork tapeworm) is perhaps most widely prevalent and well known for its association with seizures and epilepsy. Many of the other helminthic disorders have fairly restricted geographic predilections and their occurrence in much of the remaining world is limited to rare cases among travelers and immigrants. Nonetheless, knowledge about the helminthic disorders, the life cycle of their causative agents, and their clinical manifestations and diagnostic features are important in order to recognize them.

Exposure to drugs early in life has complex and long-lasting implications for brain structure and function. This review summarizes work to date on the immediate and long-term effects of prenatal exposure to cocaine. In utero cocaine exposure produces disruptions in brain monoamines, particularly dopamine, during sensitive periods of brain development, and leads to permanent changes in specific brain circuits, molecules, and behavior. Here, we integrate clinical studies and significance with mechanistic preclinical studies, to define our current knowledge base and identify gaps for future investigation. PMID:27345015

Spider bites represent an unusual and potentially over-represented clinical diagnosis. Despite a common fear of spiders, known as arachnophobia, current knowledge suggests that only a small number of families within the order Araneae are medically relevant. Moreover, most cutaneous spider reactions, including both evenomations and physical trauma, produce mild, local symptoms which may be managed with supportive care alone. The differential diagnosis for spider bites may be broad, especially if the offending arachnid is not seen or found. We describe a series of spiders relevant to the dermatologist in the United States.
Systematic reviews, systematic error and the acquisition of clinical knowledge
2010-01-01
Background Since its inception, evidence-based medicine and its application through systematic reviews, has been widely accepted. However, it has also been strongly criticised and resisted by some academic groups and clinicians. One of the main criticisms of evidence-based medicine is that it appears to claim to have unique access to absolute scientific truth and thus devalues and replaces other types of knowledge sources. Discussion The various types of clinical knowledge sources are categorised on the basis of Kant's categories of knowledge acquisition, as being either 'analytic' or 'synthetic'. It is shown that these categories do not act in opposition but rather, depend upon each other. The unity of analysis and synthesis in knowledge acquisition is demonstrated during the process of systematic reviewing of clinical trials. Systematic reviews constitute comprehensive synthesis of clinical knowledge but depend upon plausible, analytical hypothesis development for the trials reviewed. The dangers of systematic error regarding the internal validity of acquired knowledge are highlighted on the basis of empirical evidence. It has been shown that the systematic review process reduces systematic error, thus ensuring high internal validity. It is argued that this process does not exclude other types of knowledge sources. Instead, amongst these other types it functions as an integrated element during the acquisition of clinical knowledge. Conclusions The acquisition of clinical knowledge is based on interaction between analysis and synthesis. Systematic reviews provide the highest form of synthetic knowledge acquisition in terms of achieving internal validity of results. In that capacity it informs the analytic knowledge of the clinician but does not replace it. PMID:20537172

Theory suggests that personality traits evolved to have costs and benefits, with the effectiveness of a trait dependent on how these costs and benefits relate to the present circumstances. This suggests that traits that are generally viewed as positive can have a 'dark side' and those generally viewed as negative can have a 'bright side' depending on changes in context. We test this in a sample of 220 UK medical students with respect to associations between the Big 5 personality traits and learning outcomes across the 5 years of a medical degree. The medical degree offers a changing learning context from pre-clinical years (where a more methodical approach to learning is needed) to the clinical years (where more flexible learning is needed, in a more stressful context). We argue that while trait conscientiousness should enhance pre-clinical learning, it has a 'dark side' reducing the acquisition of knowledge in the clinical years. We also suggest that anxiety has a 'bright side' enhancing the acquisition of skills in the clinical years. We also explore if intelligence enhances learning across the medical degree. Using confirmatory factor analysis and structural equation modelling we show that medical skills and knowledge assessed in the pre-clinical and clinical years are psychometrically distinguishable, forming a learning 'backbone', whereby subsequent learning outcomes are predicted by previous ones. Consistent with our predictions conscientiousness enhanced preclinical knowledge acquisition but reduced the acquisition of clinical knowledge and anxiety enhanced the acquisition of clinical skills. We also identified a curvilinear U shaped association between Surgency (extraversion) and pre-clinical knowledge acquisition. Intelligence predicted initial clinical knowledge, and had a positive total indirect effect on clinical knowledge and clinical skill acquisition. For medical selection, this suggests that selecting students high on conscientiousness may be problematic, as it may be excluding those with some degree of moderate anxiety.

The broad adoption of clinical decision support systems within clinical practice has been hampered mainly by the difficulty in expressing domain knowledge and patient data in a unified formalism. This paper presents a semantic-based approach to the unified representation of healthcare domain knowledge and patient data for practical clinical decision making applications. A four-phase knowledge engineering cycle is implemented to develop a semantic healthcare knowledge base based on an HL7 reference information model, including an ontology to model domain knowledge and patient data and an expression repository to encode clinical decision making rules and queries. A semantic clinical decision support system is designed to provide patient-specific healthcare recommendations based on the knowledge base and patient data. The proposed solution is evaluated in the case study of type 2 diabetes mellitus inpatient management. The knowledge base is successfully instantiated with relevant domain knowledge and testing patient data. Ontology-level evaluation confirms model validity. Application-level evaluation of diagnostic accuracy reaches a sensitivity of 97.5%, a specificity of 100%, and a precision of 98%; an acceptance rate of 97.3% is given by domain experts for the recommended care plan orders. The proposed solution has been successfully validated in the case study as providing clinical decision support at a high accuracy and acceptance rate. The evaluation results demonstrate the technical feasibility and application prospect of our approach. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.
The MMPI Assistant: A Microcomputer Based Expert System to Assist in Interpreting MMPI Profiles
Tanner, Barry A.
1989-01-01
The Assistant is an MS DOS program to aid clinical psychologists in interpreting the results of the Minnesota Multiphasic Personality Inventory (MMPI). Interpretive hypotheses are based on the professional literature and the author's experience. After scores are entered manually, the Assistant produces a hard copy which is intended for use by a psychologist knowledgeable about the MMPI. The rules for each hypothesis appear first on the monitor, and then in the printed output, followed by the patient's scores on the relevant scales, and narrative hypotheses for the scores. The data base includes hypotheses for 23 validity configurations, 45 two-point clinical codes, 10 high scoring single-point clinical scales, and 10 low scoring single-point clinical scales. The program can accelerate the production of test reports, while insuring that actuarial rules are not overlooked. It has been especially useful as a teaching tool with graduate students. The Assistant requires an IBM PC compatible with 128k available memory, DOS 2.x or higher, and a printer.
PHEOCHROMOCYTOMA: IMPLICATIONS IN TUMORIGENESIS AND THE ACTUAL MANAGEMENT
Shah, Urvi; Giubellino, Alessio; Pacak, Karel
2012-01-01
Pheochromocytomas and paragangliomas are rare neuroendocrine catecholamine producing tumors with varied clinical presentations, biochemistries and genetic makeup. These features outline the complexity and the difficulties in studying and understanding the oncogenesis of these tumors. The study of families with genetically inherited mutations in pheochromocytoma susceptibility genes has greatly enhanced our understanding of the pathophysiology and mechanisms of oncogenesis of the disease, and consequently changed our clinical approach. Several molecular pathways and mutations in their important regulatory proteins have been identified. Such mutations are responsible for the dysregulation of metabolic pathways involved in oxygen and nutrient sensing, apoptosis regulation, cell proliferation, migration and invasion. The knowledge derived from the study of these pathways will be fundamental in the future clinical management of these patients. As a rare disease that often masks its clinical presentation, the diagnosis is frequently missed and a high level of suspicion is required. Management of this disease requires a multidisciplinary team approach and has been discussed along with advances in its treatment. PMID:22691888

This article analyses data from a longitudinal, ethnographic study conducted in the United States to examine how 100 mothers of children with genetic disorders used the Internet to interpret, produce, and circulate genetic knowledge pertaining to their child's condition. We describe how they came to value their own experiential knowledge, helped shift the boundaries of what counts as authoritative knowledge, and assumed the role of genetic citizen, fighting for specific rights while shouldering and contesting concomitant duties and obligations. This exploration of e-health use contributes to our understanding of the social practices and power relations that cut across online and off-line worlds to co-produce genetic knowledge and genetic citizenship in multiple contexts.

'Transfer' is the application of a previously learned concept to solve a new problem in another context. Transfer is essential for basic science education because, to be valuable, basic science knowledge must be transferred to clinical problem solving. Therefore, better understanding of interventions that enhance the transfer of basic science knowledge to clinical reasoning is essential. This review systematically identifies interventions described in the health professions education (HPE) literature that document the transfer of basic science knowledge to clinical reasoning, and considers teaching and assessment strategies. A systematic search of the literature was conducted. Articles related to basic science teaching at the undergraduate level in HPE were analysed using a 'transfer out'/'transfer in' conceptual framework. 'Transfer out' refers to the application of knowledge developed in one learning situation to the solving of a new problem. 'Transfer in' refers to the use of previously acquired knowledge to learn from new problems or learning situations. Of 9803 articles initially identified, 627 studies were retrieved for full text evaluation; 15 were included in the literature review. A total of 93% explored 'transfer out' to clinical reasoning and 7% (one article) explored 'transfer in'. Measures of 'transfer out' fostered by basic science knowledge included diagnostic accuracy over time and in new clinical cases. Basic science knowledge supported learning - 'transfer in' - of new related content and ultimately the 'transfer out' to diagnostic reasoning. Successful teaching strategies included the making of connections between basic and clinical sciences, the use of commonsense analogies, and the study of multiple clinical problems in multiple contexts. Performance on recall tests did not reflect the transfer of basic science knowledge to clinical reasoning. Transfer of basic science knowledge to clinical reasoning is an essential component of HPE that requires further development for implementation and scholarship. © 2018 John Wiley & Sons Ltd and The Association for the Study of Medical Education.
Global standards and local knowledge building: Upgrading small producers in developing countries
Perez-Aleman, Paola
2012-01-01
Local knowledge building is a crucial factor for upgrading small producers and improving their market competitiveness and livelihoods. The rise of global standards affecting food safety and environmental sustainability in agriculture sparks debates on the impact on smallholders in developing countries. This article presents a perspective on the links of international standards to knowledge and institution building for developing the capabilities of small producers. Interacting with global practices, indigenous private and public actors create local institutions to develop capabilities for product and process innovations that contribute to economic development and enhance food security. Local innovation depends on collective strategic efforts through increasing networks among small producers and other organizations, including firms, nongovernmental organizations, and government, that foster knowledge circulation and bring diverse resources and support to build local capabilities.

The emergence of carbapenem-resistant Escherichia coli has become a serious challenge to manage in the clinic because of multidrug resistance. Here we report the draft genome sequence of NDM-3-producing E. coli strain NT1 isolated from a bloodstream infection in China. Whole genomic DNA of E. coli strain NT1 was extracted and was sequenced using an Illumina HiSeq™ X Ten platform. The generated sequence reads were assembled using CLC Genomics Workbench. The draft genome was annotated using Rapid Annotation using Subsystem Technology (RAST). Bioinformatics analysis was further performed. The genome size was calculated at 5,353 620bp, with 5297 protein-coding sequences and the presence of genes conferring resistance to aminoglycosides, β-lactams, quinolones, macrolides, phenicols, sulphonamides, tetracycline and trimethoprim. In addition, genes encoding virulence factors were also identified. To our knowledge, this is the first report of an E. coli strain producing NDM-3 isolated from a human bloodstream infection. The genome sequence will provide valuable information to understand antibiotic resistance mechanisms and pathogenic mechanisms in this strain. Close surveillance is urgently needed to monitor the spread of NDM-3-producing isolates. Copyright © 2018 International Society for Chemotherapy of Infection and Cancer. Published by Elsevier Ltd.

Background Today’s medical students are the future physicians of people living with HIV/AIDS (PLWHA). It is therefore essential that medical students possess the appropriate knowledge and attitudes regarding PLWHA. This study aims to evaluate knowledge and attitudes of pre-clinical Israeli medical students and to assess whether their knowledge and attitudes change throughout their pre-clinical studies. Methods A cross-sectional study was conducted among all pre-clinical medical students from the four medical schools in Israel during the academic year of 2010/2011 (a total of 1,470 students). A self-administered questionnaire was distributed. The questionnaire sought student responses pertaining to knowledge of HIV transmission and non-transmission routes, basic knowledge of HIV/AIDS treatment and attitudes towards HIV/AIDS. Results The study’s response rate was 62.24 percent. Knowledge among pre-clinical medical students was generally high and showed a statistically significant improvement as students progressed through their pre-clinical studies. However, there were some misconceptions, mostly regarding HIV transmission via breastfeeding and knowledge of HIV prevention after exposure to the virus. Students’ attitudes were found to include stigmatizing notions. Furthermore, the majority of medical students correlated HIV with shame and fear. In addition, students’ attitudes toward HIV testing and providing confidential medical information were contradictory to health laws, protocols and guidelines. Overall, no positive changes in students’ attitudes were observed during the pre-clinical years of medical school. Conclusion The knowledge of pre-clinical medical students in Israel is generally high, although there are some knowledge inadequacies that require more emphasis in the curricula of the medical schools. Contrary to HIV-related knowledge, medical students’ attitudes are unaffected by their progression through medical school. Therefore, medical schools in Israel should modify their curricula to include teaching methods aimed at improving HIV-related attitudes and adherence to medical professionalism. PMID:24650351

A changing undergraduate demographic and the need to help students develop advanced critical thinking skills in neuroanatomy courses has prompted many faculty to consider new teaching methods including clinical case studies. This study compared primarily conventional and inquiry-based clinical case (IBCC) teaching methods to determine which would produce greater gains in critical thinking and content knowledge. Results showed students in the conventional neuroanatomy course gained less than 3 national percentile ranks while IBCC students gained over 7.5 within one academic term using the valid and reliable California Critical Thinking Skills Test. In addition to 2.5 times greater gains in critical thinking, IBCC teaching methods also produced 12% greater final exam performance and 11% higher grades using common grade performance benchmarks. Classroom observations also indicated that IBCC students were more intellectually engaged and participated to a greater extent in classroom discussions. Through the results of this study, it is hoped that faculty who teach neuroanatomy and desire greater critical thinking and content student learning outcomes will consider using the IBCC method.

A comprehensive knowledge of mitral valve (MV) anatomy is crucial in the assessment of MV disease. While the use of three-dimensional (3D) modelling and printing in MV assessment has undergone early clinical evaluation, the precision and usefulness of this technology requires further investigation. This study aimed to assess and validate 3D modelling and printing technology to produce patient-specific 3D MV models. A prototype method for MV 3D modelling and printing was developed from computed tomography (CT) scans of a plastinated human heart. Mitral valve models were printed using four 3D printing methods and validated to assess precision. Cardiac CT and 3D echocardiography imaging data of four MV disease patients was used to produce patient-specific 3D printed models, and 40 cardiac health professionals (CHPs) were surveyed on the perceived value and potential uses of 3D models in a clinical setting. The prototype method demonstrated submillimetre precision for all four 3D printing methods used, and statistical analysis showed a significant difference (p<0.05) in precision between these methods. Patient-specific 3D printed models, particularly using multiple print materials, were considered useful by CHPs for preoperative planning, as well as other applications such as teaching and training. This study suggests that, with further advances in 3D modelling and printing technology, patient-specific 3D MV models could serve as a useful clinical tool. The findings also highlight the potential of this technology to be applied in a variety of medical areas within both clinical and educational settings.

Knowledge transfer to clinicians and consumers by the Cochrane Musculoskeletal Group.
Santesso, Nancy; Maxwell, Lara; Tugwell, Peter S; Wells, George A; O'connor, Annette M; Judd, Maria; Buchbinder, Rachelle

The Cochrane Musculoskeletal Group (CMSG) is one of 50 groups of the Cochrane Collaboration that prepares, maintains, and disseminates systematic reviews of treatments for musculoskeletal diseases. Once systematic reviews are completed, the next challenge is presenting the results in useful formats to be integrated into the healthcare decisions of clinicians and consumers. The CMSG recommends 3 methods to aid knowledge translation and exchange between clinicians and patients: produce clinical relevance tables, create graphical displays using face figures, and write consumer summaries and patient decision aids. Accordingly, CMSG has developed specific guidelines to help researchers and authors convert the pooled estimates of metaanalyses in the systematic reviews to user-friendly numbers. First, clinical relevance tables are developed that include absolute and relative benefits or harms and the numbers needed to treat. Next, the numbers from the clinical relevance tables are presented graphically using faces. The faces represent a group of 100 people and are shaded according to how many people out of 100 benefited or were harmed by the interventions. The user-friendly numbers are also included in short summaries and decision aids written for patients. The different levels of detail in the summaries and decision aids provide patients with tools to prepare them to discuss treatment options with their clinicians. Methods to improve the effects and usability of systematic reviews by providing results in more clinically relevant formats are essential. Both clinicians and consumers can use these products to use evidence-based information in individual and shared decision-making.

In organisational theory there is an assumption that knowledge is used effectively in healthcare systems that perform well. Actors in healthcare systems focus on managing knowledge of clinical processes like, for example, clinical decision-making to improve patient care. We know little about connecting that knowledge to administrative processes like high-risk medical device procurement. We analysed knowledge-related factors that influence procurement and clinical procedures for orthopaedic medical devices in Mexico. We based our qualitative study on 48 semi-structured interviews with various stakeholders in Mexico: orthopaedic specialists, government officials, and social security system managers or administrators. We took a knowledge-management related perspective (i) to analyse factors of managing knowledge of clinical procedures, (ii) to assess the role of this knowledge and in relation to procurement of orthopaedic medical devices, and (iii) to determine how to improve the situation. The results of this study are primarily relevant for Mexico but may also give impulsion to other health systems with highly standardized procurement practices. We found that knowledge of clinical procedures in orthopaedics is generated inconsistently and not always efficiently managed. Its support for procuring orthopaedic medical devices is insufficient. Identified deficiencies: leaders who lack guidance and direction and thus use knowledge poorly; failure to share knowledge; insufficiently defined formal structures and processes for collecting information and making it available to actors of health system; lack of strategies to benefit from synergies created by information and knowledge exchange. Many factors are related directly or indirectly to technological aspects, which are insufficiently developed. The content of this manuscript is novel as it analyses knowledge-related factors that influence procurement of orthopaedic medical devices in Mexico. Based on our results we recommend that the procurement mechanism should integrate knowledge from clinical procedures adequately in their decision-making. Without strong guidance, organisational changes, and support by technological solutions to improve the generation and management of knowledge, procurement processes for orthopaedic high-risk medical devices will remain sub-optimal.

Advances in genetics have had a profound impact on health care. Yet, many nurses, as well as other health care providers, have limited genetic knowledge and feel uncomfortable integrating genetics into their practice. Very little is known about perceived genetic knowledge and clinical comfort among Taiwanese nurses enrolled in a Registered Nurse to Bachelor of Science in Nursing program. To examine perceived knowledge and clinical comfort with genetics among Taiwanese nurses enrolled in a Registered Nurse to Bachelor of Science in Nursing program and to assess how genetics has been integrated into their past and current nursing programs. The study also sought to examine correlations among perceived knowledge, integration of genetics into the nursing curriculum, and clinical comfort with genetics. A descriptive, cross-sectional study. Taiwanese nurses enrolled in a Registered Nurse to Bachelor of Science in Nursing program were recruited. A total of 190 of 220 nurses returned the completed survey (86.36% response rate). Descriptive statistics and the Pearson product-moment correlation were used for data analysis. Most nurses indicated limited perceived knowledge and clinical comfort with genetics. Curricular hours focused on genetics in a current nursing program were greater than those in past nursing programs. The use of genetic materials, attendance at genetic workshops and conferences, and clinically relevant genetics in nursing practice significantly related with perceived knowledge and clinical comfort with genetics. However, there were no correlations between prior genetic-based health care, perceived knowledge, and clinical comfort with genetics. This study demonstrated the need for emphasizing genetic education and practice to ensure health-related professionals become knowledgeable about genetic information. Given the rapidly developing genetic revolution, nurses and other health care providers need to utilize genetic discoveries to optimize health outcomes. Copyright © 2012 Elsevier Ltd.

The creation of clinical decision support systems has received a strong impulse over the last years, but their integration into a clinical routine has lagged behind, partly due to a lack of interoperability and trust by physicians. We report on the implementation of a clinical foundation framework in Arden Syntax, comprising knowledge units for (a) preprocessing raw clinical data, (b) the determination of single clinical concepts, and (c) more complex medical knowledge, which can be modeled through the composition and configuration of knowledge units in this framework. Thus, it can be tailored to clinical institutions or patients' caregivers. In the present version, we integrated knowledge units for several infection-related clinical concepts into the framework and developed a clinical event monitoring system over the framework that employs three different scenarios for monitoring clinical signs of bloodstream infection. The clinical event monitoring system was tested using data from intensive care units at Vienna General Hospital, Austria.
KAT: A Flexible XML-based Knowledge Authoring Environment

As part of an enterprise effort to develop new clinical information systems at Intermountain Health Care, the authors have built a knowledge authoring tool that facilitates the development and refinement of medical knowledge content. At present, users of the application can compose order sets and an assortment of other structured clinical knowledge documents based on XML schemas. The flexible nature of the application allows the immediate authoring of new types of documents once an appropriate XML schema and accompanying Web form have been developed and stored in a shared repository. The need for a knowledge acquisition tool stems largely from the desire for medical practitioners to be able to write their own content for use within clinical applications. We hypothesize that medical knowledge content for clinical use can be successfully created and maintained through XML-based document frameworks containing structured and coded knowledge.

Visual impairment is a significant public health concern, particularly in low- and middle-income countries where eye care is predominantly provided at the primary healthcare (PHC) level, known as primary eye care. This study aimed to perform an evaluation of primary eye care services in three districts of South Africa and to assess whether an ophthalmic health system strengthening (HSS) package could improve these services. Baseline surveys were conducted in Cape Winelands District, Johannesburg Health District and Mopani District at 14, 25 and 36 PHC facilities, respectively. Thereafter, the HSS package, comprising group training, individual mentoring, stakeholder engagement and resource provision, was implemented in 20 intervention sites in Mopani District, with the remaining 16 Mopani facilities serving as control sites. At baseline, less than half the facilities in Johannesburg and Mopani had dedicated eye care personnel or sufficient space to measure visual acuity. Although visual acuity charts were available in most facilities, <50% assessed patients at the correct distance. Median score for availability of nine essential drugs was <70%. Referral criteria knowledge was highest in Cape Winelands and Johannesburg, with poor clinical knowledge across all districts. Several HSS interventions produced successful outcomes: compared to control sites there was a significant increase in the proportion of intervention sites with eye care personnel and resources such as visual acuity charts (p = 0.02 and <0.01, respectively). However, engaging with district pharmacists did not improve availability of essential drugs (p = 0.47). Referral criteria knowledge improved significantly in intervention sites (p<0.01) but there was no improvement in clinical knowledge (p = 0.76). Primary eye care in South Africa faces multiple challenges with regard to organisation of care, resource availability and clinical competence. The HSS package successfully improved some aspects of this care, but further development is warranted together with debate regarding the positioning of eye services at PHC level. PMID:29758069

Background Obtaining informed consent for clinical trials is especially challenging when working in rural, resource-limited areas, where there are often high levels of illiteracy and lack of experience with clinical research. Such an area, a remote field site in the northeastern part of the state of Minas Gerais, Brazil, is currently being prepared for clinical trials of experimental hookworm vaccines. This study was conducted to assess whether special educational tools can be developed to increase the knowledge and comprehension of potential clinical trial participants and thereby enable them to make truly informed decisions to participate in such research. Methodology/Principal Findings An informational video was produced to explain the work of the research team and the first planned hookworm vaccine trial, using a pedagogical method based on analogies. Seventy-two adults living in a rural community of Minas Gerais were administered a structured questionnaire that assessed their knowledge of hookworm, of research and of the planned hookworm vaccine trial, as well as their attitudes and perceptions about the researchers and participation in future vaccine trials. The questionnaire was administered before being shown the educational video and two months after and the results compared. After viewing the video, significant improvements in knowledge related to hookworm infection and its health impact were observed: using a composite score combining related questions for which correct answers were assigned a value of 1 and incorrect answers a value of 0, participants had a mean score of 0.76 post-video compared to 0.68 pre-video (p = 0.0001). Similar improvements were seen in understanding the purpose of vaccination and the possible adverse effects of an experimental vaccine. Although 100% of participants expressed a positive opinion of the researchers even before viewing the film and over 90% said that they would participate in a hookworm vaccine trial, an increase in the number who expressed fear of being vaccinated with a novel vaccine was seen after viewing the video (51.4% post-video versus 29.2% pre-video). Increases were also seen in the proportion who thought that participation in a vaccine trial would be inconvenient or disrupt their daily activities. Conclusions/Significance Even in rural, resource-limited populations, educational tools can be specially designed that significantly improve understanding and therefore the likelihood of obtaining truly informed consent for participation in clinical research. The observed changes in the knowledge and perceptions of the research participants about hookworm infection and the experimental hookworm vaccine demonstrate that the video intervention was successful in increasing understanding and that the subjects acquired knowledge pertinent to the planned research.

Most references to "leadership" and "learning" as sources of quality improvement in medical care reflect an implicit commitment to the decision technology of "clinical judgement". All attempts to sustain this waning decision technology by clinical guidelines, care pathways, "evidence based practice", problem based curricula, and other stratagems only increase the gap between what is expected of doctors in today's clinical situation and what is humanly possible, hence the morale, stress, and health problems they are increasingly experiencing. Clinical guidance programmes based on decision analysis represent the coming decision technology, and proactive adaptation will produce independent doctors who can deliver excellent evidence based and preference driven care while concentrating on the human aspects of the therapeutic relation, having been relieved of the unbearable burdens of knowledge and information processing currently laid on them. History is full of examples of the incumbents of dominant technologies preferring to die than to adapt, and medicine needs both learning and leadership if it is to avoid repeating this mistake. Key Words: decision technology; clinical guidance programmes; decision analysis PMID:11700381
Problem-based learning: a review of the educational and psychological theory.
Onyon, Clare
2012-02-01
Problem-based learning (PBL) is a teaching method where the use of clinical problems is the starting point for learning, and it is through the process of working through these problems that students acquire the knowledge and skills required to be a doctor. Many advantages of PBL over traditional curricula have been proposed. On reviewing the evidence on the results of PBL curricula for producing better doctors, students tend to perform either a little better or a little worse in examinations. In this article the educational and psychological theories supporting PBL are described. There is a wealth of theory underpinning the use of PBL to teach clinical medicine, despite disappointing results. Future research should concentrate on the reasons behind this uncoupling of theory and outcomes. © Blackwell Publishing Ltd 2012.
Ductal carcinoma in situ: USC/Van Nuys Prognostic Index and the impact of margin status.
Silverstein, Melvin J; Buchanan, Claire
2003-12-01
As our knowledge of ductal carcinoma in situ (DCIS) continues to evolve, treatment decision-making has become increasingly complex and controversial for both patients and physicians. Treatment options include mastectomy, and breast conservation with or without radiation therapy. Data produced from the randomized clinical trials for DCIS has provided the basis for important treatment recommendations, but are not without limitations. In this article, we review our prospectively collected database consisting of 1036 patients with DCIS treated at the Van Nuys Breast Center and the USC/Norris Comprehensive Cancer Center. We review the use of the USC/Van Nuys Prognostic Index, a clinical algorithm designed to assist physicians in selection of appropriate treatments, and examine the impact of margin status as a sole predictor of local recurrence.
Tools developed and disseminated by guideline producers to promote the uptake of their guidelines.

The uptake of clinical practice guidelines (CPGs) is inconsistent, despite their potential to improve the quality of health care and patient outcomes. Some guideline producers have addressed this problem by developing tools to encourage faster adoption of new guidelines. This review focuses on the effectiveness of tools developed and disseminated by guideline producers to improve the uptake of their CPGs. To evaluate the effectiveness of implementation tools developed and disseminated by guideline producers, which accompany or follow the publication of a CPG, to promote uptake. A secondary objective is to determine which approaches to guideline implementation are most effective. We searched the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL); NHS Economic Evaluation Database, HTA Database; MEDLINE and MEDLINE In-Process and other non-indexed citations; Embase; PsycINFO; CINAHL; Dissertations and Theses, ProQuest; Index to Theses; Science Citation Index Expanded, ISI Web of Knowledge; Conference Proceedings Citation Index - Science, ISI Web of Knowledge; Health Management Information Consortium (HMIC), and NHS Evidence up to February 2016. We also searched trials registers, reference lists of included studies and relevant websites. We included randomised controlled trials (RCTs) and cluster-RCTs, controlled before-and-after studies (CBAs) and interrupted time series (ITS) studies evaluating the effects of guideline implementation tools developed by recognised guideline producers to improve the uptake of their own guidelines. The guideline could target any clinical area. Two review authors independently extracted data and assessed the risk of bias of each included study using the Cochrane 'Risk of bias' criteria. We graded our confidence in the evidence using the approach recommended by the GRADE working group. The clinical conditions targeted and the implementation tools used were too heterogenous to combine data for meta-analysis. We report the median absolute risk difference (ARD) and interquartile range (IQR) for the main outcome of adherence to guidelines. We included four cluster-RCTs that were conducted in the Netherlands, France, the USA and Canada. These studies evaluated the effects of tools developed by national guideline producers to implement their CPGs. The implementation tools evaluated targeted healthcare professionals; none targeted healthcare organisations or patients.One study used two short educational workshops tailored to barriers. In three studies the intervention consisted of the provision of paper-based educational materials, order forms or reminders, or both. The clinical condition, type of healthcare professional, and behaviour targeted by the CPG varied across studies.Two of the four included studies reported data on healthcare professionals' adherence to guidelines. A guideline tool developed by the producers of a guideline probably leads to increased adherence to the guidelines; median ARD (IQR) was 0.135 (0.115 and 0.159 for the two studies respectively) at an average four-week follow-up (moderate certainty evidence), which indicates a median 13.5% greater adherence to guidelines in the intervention group. Providing healthcare professionals with a tool to improve implementation of a guideline may lead to little or no difference in costs to the health service. Implementation tools developed by recognised guideline producers probably lead to improved healthcare professionals' adherence to guidelines in the management of non-specific low back pain and ordering thyroid-function tests. There are limited data on the relative costs of implementing these interventions.There are no studies evaluating the effectiveness of interventions targeting the organisation of care (e.g. benchmarking tools, costing templates, etc.), or for mass media interventions. We could not draw any conclusions about our second objective, the comparative effectiveness of implementation tools, due to the small number of studies, the heterogeneity between interventions, and the clinical conditions that were targeted.

Impact of voice- and knowledge-enabled clinical reporting--US example.
Bushko, Renata G; Havlicek, Penny L; Deppert, Edward; Epner, Stephen
2002-01-01
This study shows qualitative and quantitative estimates of the national and the clinic level impact of utilizing voice and knowledge enabled clinical reporting systems. Using common sense estimation methodology, we show that the delivery of health care can experience a dramatic improvement in four areas as a result of the broad use of voice and knowledge enabled clinical reporting: (1) Process Quality as measured by cost savings, (2) Organizational Quality as measured by compliance, (3) Clinical Quality as measured by clinical outcomes and (4) Service Quality as measured by patient satisfaction. If only 15 percent of US physicians replaced transcription with modem clinical reporting voice-based methodology, about one half billion dollars could be saved. $6.7 Billion could be saved annually if all medical reporting currently transcribed was handled with voice-and knowledge-enabled dictation and reporting systems.

Clinical simulations can provide students with realistic clinical learning environments to increase their knowledge, self-confidence, and decrease their anxiety prior to entering clinical practice settings. To compare the effectiveness of two maternal newborn clinical simulation scenarios; virtual clinical simulation and face-to-face high fidelity manikin simulation. Randomized pretest-posttest design. A public research university in Canada. Fifty-six third year Bachelor of Science in Nursing students. Participants were randomized to either face-to-face or virtual clinical simulation and then to dyads for completion of two clinical simulations. Measures included: (1) Nursing Anxiety and Self-Confidence with Clinical Decision Making Scale (NASC-CDM) (White, 2011), (2) knowledge pretest and post-test related to preeclampsia and group B strep, and (3) Simulation Completion Questionnaire. Before and after each simulation students completed a knowledge test and the NASC-CDM and the Simulation Completion Questionnaire at study completion. There were no statistically significant differences in student knowledge and self-confidence between face-to-face and virtual clinical simulations. Anxiety scores were higher for students in the virtual clinical simulation than for those in the face-to-face simulation. Students' self-reported preference was face-to-face citing the similarities to practicing in a 'real' situation and the immediate debrief. Students not liking the virtual clinical simulation most often cited technological issues as their rationale. Given the equivalency of knowledge and self-confidence when undergraduate nursing students participate in either maternal newborn clinical scenarios of face-to-face or virtual clinical simulation identified in this trial, it is important to take into the consideration costs and benefits/risks of simulation implementation.

The new generation of health information standards, where the syntax and semantics of the content is explicitly formalized, allows for interoperability in healthcare scenarios and analysis in clinical research settings. Studies involving clinical and genomic data include accumulating knowledge as relationships between genotypic and phenotypic information as well as associations within the genomic and clinical worlds. Some involve analysis results targeted at a specific disease; others are of a predictive nature specific to a patient and may be used by decision support applications. Representing knowledge is as important as representing data since data is more useful when coupled with relevant knowledge. Any further analysis and cross-research collaboration would benefit from persisting knowledge and data in a unified way. This paper describes a methodology used in Hypergenes, an EC FP7 project targeting Essential Hypertension, which captures data and knowledge using standards such as HL7 CDA and Clinical Genomics, aligned with the CEN EHR 13606 specification. We demonstrate the benefits of such an approach for clinical research as well as in healthcare oriented scenarios.
Nursing knowledge: hints from the placebo effect.
Zanotti, Renzo; Chiffi, Daniele
2017-07-01
Nursing knowledge stems from a dynamic interplay between population-based scientific knowledge (the general) and specific clinical cases (the particular). We compared the 'cascade model of knowledge translation', also known as 'classical biomedical model' in clinical practice (in which knowledge gained at population level may be applied directly to a specific clinical context), with an emergentist model of knowledge translation. The structure and dynamics of nursing knowledge are outlined, adopting the distinction between epistemic and non-epistemic values. Then, a (moderately) emergentist approach to nursing knowledge is proposed, based on the assumption of a two-way flow from the general to the particular and vice versa. The case of the 'placebo effect' is analysed as an example of emergentist knowledge. The placebo effect is usually considered difficult to be explained within the classical biomedical model, and we underscore its importance in shaping nursing knowledge. In fact, nurses are primarily responsible for administering placebo in the clinical setting and have an essential role in promoting the placebo effect and reducing the nocebo effect. The beliefs responsible for the placebo effect are as follows: (1) interactive, because they depend on the relationship between patients and health care professionals; (2) situated, because they occur in a given clinical context related to certain rituals; and (3) grounded on higher order beliefs concerning what an individual thinks about the beliefs of others. It is essential to know the clinical context and to understand other people's beliefs to make sense of the placebo effect. The placebo effect only works when the (higher order) beliefs of doctors, nurses and patients interact in a given setting. Finally, we argue for a close relationship between placebo effect and nursing knowledge. © 2016 John Wiley & Sons Ltd.

Opioid, cannabinoid, and transient receptor potential (TRP) systems: effects on body temperature
Rawls, Scott M.; Benamar, Khalid
2014-01-01
Cannabinoid and opioid drugs produce marked changes in body temperature. Recent findings have extended our knowledge about the thermoregulatory effects of cannabinoids and opioids, particularly as related to delta opioid receptors, endogenous systems, and transient receptor potential (TRP) channels. Although delta opioid receptors were originally thought to play only a minor role in thermoregulation compared to mu and kappa opioid receptors, their activation has been shown to produce hypothermia in multiple species. Endogenous opioids and cannabinoids also regulate body temperature. Mu and kappa opioid receptors are thought to be in tonic balance, with mu and kappa receptor activation producing hyperthermia and hypothermia, respectively. Endocannabinoids participate in the febrile response, but more studies are needed to determine if a cannabinoid CB1 receptor tone exerts control over basal body temperature. A particularly intense research focus is TRP channels, where TRPV1 channel activation produces hypothermia whereas TRPA1 and TRPM8 channel activation causes hyperthermia. The marked hyperthermia produced by TRPV1 channel antagonists suggests these warm channels tonically control body temperature. A better understanding of the roles of cannabinoid, opioid, and TRP systems in thermoregulation may have broad clinical implications and provide insights into interactions among neurotransmitter systems involved in thermoregulation.

Comparative Effectiveness and Implementation Research: Directions for Neurology
Vickrey, Barbara G.; Hirtz, Deborah; Waddy, Salina; Cheng, Eric M.; Johnston, S. Claiborne
2013-01-01
There is an enormous unmet need for knowledge about how new insights from discovery and translational research can yield measurable, population-level improvements in health and reduction in mortality among those having or at risk for neurological disease. Once several, well-conducted randomized controlled trials establish the efficacy of a given therapy, implementation research can generate new knowledge about barriers to uptake of the therapy into widespread clinical care, and what strategies are effective in overcoming those barriers and in addressing health disparities. Comparative effectiveness research aims to elucidate the relative value (including clinical benefit, clinical harms, and/or costs) of alternative efficacious management approaches to a neurological disorder, generally through direct comparisons, and may include comparisons of methodologies for implementation. Congress has recently appropriated resources and established an institute to prioritize funding for such research. Neurologists and neuroscientists should understand the scope and objectives of comparative effectiveness and implementation research, their range of methodological approaches (formal literature syntheses, randomized trials, observational studies, modeling), and existing research resources (centers for literature synthesis, registries, practice networks) relevant to research for neurological conditions, in order to close the well-documented “evidence-to-practice gap.” Future directions include building this research resource capacity, producing scientists trained to conduct rigorous comparative effectiveness and implementation research, and embracing innovative strategies to set research priorities in these areas.

Importance of Recognizing Carpal Tunnel Syndrome for Neurosurgeons: A Review
YUNOKI, Masatoshi; KANDA, Takahiro; SUZUKI, Kenta; UNEDA, Atsuhito; HIRASHITA, Koji; YOSHINO, Kimihiro
2017-01-01
Idiopathic carpal tunnel syndrome (CTS) is a common complaint, reflecting entrapment neuropathy of the upper extremity. CTS produces symptoms similar to those of other conditions, such as cervical spondylosis or ischemic or neoplastic intracranial disease. Because of these overlaps, patients with CTS are often referred to a neurosurgeon. Surgical treatment of CTS was started recently in our department. Through this experience, we realized that neurosurgeons should have an increased awareness of this condition so they can knowledgeably assess patients with a differential diagnosis that includes CTS and cervical spinal and cerebral disease. We conducted a literature review to gain the information needed to summarize current knowledge on the clinical, pathogenetic, and therapeutic aspects of CTS. Because the optimal diagnostic criteria for this disease are still undetermined, its diagnosis is based on the patient’s history and physical examination, which should be confirmed by nerve conduction studies and imaging modalities such as magnetic resonance imaging and ultrasonography. Treatment methods include observation, medication, splinting, steroid injections, and surgical intervention. Understanding the clinical features and pathogenesis of CTS, as well as the therapeutic options available to treat it, is important for neurosurgeons if they are to provide the correct management of patients with this disease.

[Prescription of drugs of systemic use by dentists].
Castilho, L S; Paixão, H H; Perini, E
1999-06-01
The study of the prescription pattern of antibacterial and analgesic/antiinflammatory systemic medication by dentists. Observational study based in questionnaires answered by a representative, randomly selected sample of 163 general dentists from the Metropolitan Region of Belo Horizonte, Southeastern Brazil. Some of the topics verified were: the most frequently prescribed drugs in the fortnight prior to the study, the use of generic names of drugs in the prescriptions, attendance at refresher courses on pharmacology, self-assessment of degree of knowledge on pharmacology, the importance given to this subject in the dentist's professional career, and the filling out of the clinical chart and the registration of the drugs prescribed on it. It was observed that the drugs were usually prescribed by their commercial name. There were a trend to prescribe more antiinflamatory than analgesics drugs. A small, but worrying, 13% of dentists didnot fill out the clinical chart for all the patients and 43% of the sample didnot register the drugs prescribed on it. The courses on pharmacology seemed to produce no significant alteration in self valuation as to the degree of knowledge in pharmacology and the use of the generic names of drugs.

Knowledge of the genetic changes that lead to disease has grown and continues to grow at a rapid pace. However, there is a need for clinical devices that can be used routinely to translate this knowledge into the treatment of patients. Use in a clinical setting requires high sensitivity and specificity (>97%) in order to prevent misdiagnoses. Single-strand conformational polymorphism (SSCP) and heteroduplex analysis (HA) are two DNA-based, complementary methods for mutation detection that are inexpensive and relatively easy to implement. However, both methods are most commonly detected by slab gel electrophoresis, which can be labor-intensive, time-consuming, and often the methods are unable to produce high sensitivity and specificity without the use of multiple analysis conditions. Here, we demonstrate the first blinded study using microchip electrophoresis (ME)-SSCP/HA. We demonstrate the ability of ME-SSCP/HA to detect with 98% sensitivity and specificity >100 samples from the p53 gene exons 5-9 in a blinded study in an analysis time of <10 min.

A knowledge authoring tool for clinical decision support.
Dunsmuir, Dustin; Daniels, Jeremy; Brouse, Christopher; Ford, Simon; Ansermino, J Mark
2008-06-01
Anesthesiologists in the operating room are unable to constantly monitor all data generated by physiological monitors. They are further distracted by clinical and educational tasks. An expert system would ideally provide assistance to the anesthesiologist in this data-rich environment. Clinical monitoring expert systems have not been widely adopted, as traditional methods of knowledge encoding require both expert medical and programming skills, making knowledge acquisition difficult. A software application was developed for use as a knowledge authoring tool for physiological monitoring. This application enables clinicians to create knowledge rules without the need of a knowledge engineer or programmer. These rules are designed to provide clinical diagnosis, explanations and treatment advice for optimal patient care to the clinician in real time. By intelligently combining data from physiological monitors and demographical data sources the expert system can use these rules to assist in monitoring the patient. The knowledge authoring process is simplified by limiting connective relationships between rules. The application is designed to allow open collaboration between communities of clinicians to build a library of rules for clinical use. This design provides clinicians with a system for parameter surveillance and expert advice with a transparent pathway of reasoning. A usability evaluation demonstrated that anesthesiologists can rapidly develop useful rules for use in a predefined clinical scenario.

To describe the adequacy of research information among people with cancer at the time they accept or decline participation in a cancer clinical trial. Cross-sectional, descriptive. An urban, academic, National Cancer Institute-designated comprehensive cancer center. 197 patients with advanced gastrointestinal cancer. Mailed survey; self-reported data. Adequacy of research information (actual knowledge, perceived adequacy of information, and perceived understanding), cancer clinical trial participation, and satisfaction with the decision to participate. Most respondents (88%) perceived themselves as having adequate information to make an informed decision regarding cancer clinical trial participation. In addition, 35% demonstrated adequate knowledge of basic clinical research. Patients decide to accept or decline cancer clinical trials without having adequate knowledge. Nurses have an important role in educating patients regarding cancer clinical trials. The ideal teachable moment may not occur at the time of diagnosis; other less stressful opportunities may present when the patient is more receptive.
Current Status and Future Prospects of Clinical Psycholog
Baker, Timothy B.; McFall, Richard M.; Shoham, Varda

SUMMARY The escalating costs of health care and other recent trends have made health care decisions of great societal import, with decision-making responsibility often being transferred from practitioners to health economists, health plans, and insurers. Health care decision making increasingly is guided by evidence that a treatment is efficacious, effective–disseminable, cost-effective, and scientifically plausible. Under these conditions of heightened cost concerns and institutional–economic decision making, psychologists are losing the opportunity to play a leadership role in mental and behavioral health care: Other types of practitioners are providing an increasing proportion of delivered treatment, and the use of psychiatric medication has increased dramatically relative to the provision of psychological interventions. Research has shown that numerous psychological interventions are efficacious, effective, and cost-effective. However, these interventions are used infrequently with patients who would benefit from them, in part because clinical psychologists have not made a convincing case for the use of these interventions (e.g., by supplying the data that decision makers need to support implementation of such interventions) and because clinical psychologists do not themselves use these interventions even when given the opportunity to do so. Clinical psychologists’ failure to achieve a more significant impact on clinical and public health may be traced to their deep ambivalence about the role of science and their lack of adequate science training, which leads them to value personal clinical experience over research evidence, use assessment practices that have dubious psychometric support, and not use the interventions for which there is the strongest evidence of efficacy. Clinical psychology resembles medicine at a point in its history when practitioners were operating in a largely prescientific manner. Prior to the scientific reform of medicine in the early 1900s, physicians typically shared the attitudes of many of today’s clinical psychologists, such as valuing personal experience over scientific research. Medicine was reformed, in large part, by a principled effort by the American Medical Association to increase the science base of medical school education. Substantial evidence shows that many clinical psychology doctoral training programs, especially PsyD and for-profit programs, do not uphold high standards for graduate admission, have high student–faculty ratios, deemphasize science in their training, and produce students who fail to apply or generate scientific knowledge. A promising strategy for improving the quality and clinical and public health impact of clinical psychology is through a new accreditation system that demands highquality science training as a central feature of doctoral training in clinical psychology. Just as strengthening training standards in medicine markedly enhanced the quality of health care, improved training standards in clinical psychology will enhance health and mental health care. Such a system will (a) allow the public and employers to identify scientifically trained psychologists; (b) stigmatize ascientific training programs and practitioners; (c) produce aspirational effects, thereby enhancing training quality generally; and (d) help accredited programs improve their training in the application and generation of science. These effects should enhance the generation, application, and dissemination of experimentally supported interventions, thereby improving clinical and public health. Experimentally based treatments not only are highly effective but also are cost-effective relative to other interventions; therefore, they could help control spiraling health care costs. The new Psychological Clinical Science Accreditation System (PCSAS) is intended to accredit clinical psychology training programs that offer highquality science-centered education and training, producing graduates who are successful in generating and applying scientific knowledge. Psychologists, universities, and other stakeholders should vigorously support this new accreditation system as the surest route to a scientifically principled clinical psychology that can powerfully benefit clinical and public health.

Little research has been completed exploring knowledge development and transfer from and between simulated and clinical practice settings in nurse education. This study sought to explore the content learned, and the knowledge transferred, in a hybrid mental health clinical course consisting of simulated and clinical setting experiences. A qualitative, interpretive descriptive study design. Clinical practice consisted of six 10-hour shifts in a clinical setting combined with six two-hour simulations. 12 baccalaureate nursing students enrolled in a compressed time frame program at a large, urban, Canadian university participated. Document analysis and a focus group were used to draw thematic representations of content and knowledge transfer between clinical environments (i.e., simulated and clinical settings) using the constant comparative data analysis technique. Four major themes arose: (a) professional nursing behaviors; (b) understanding of the mental health nursing role; (c) confidence gained in interview skills; and, (d) unexpected learning. Nurse educators should further explore the intermingling of simulation and clinical practice in terms of knowledge development and transfer with the goal of preparing students to function within the mental health nursing specialty.

Basic Sciences Fertilizing Clinical Microbiology and Infection Management.
Baquero, Fernando
2017-08-15
Basic sciences constitute the most abundant sources of creativity and innovation, as they are based on the passion of knowing. Basic knowledge, in close and fertile contact with medical and public health needs, produces distinct advancements in applied sciences. Basic sciences play the role of stem cells, providing material and semantics to construct differentiated tissues and organisms and enabling specialized functions and applications. However, eventually processes of "practice deconstruction" might reveal basic questions, as in de-differentiation of tissue cells. Basic sciences, microbiology, infectious diseases, and public health constitute an epistemological gradient that should also be an investigational continuum. The coexistence of all these interests and their cross-fertilization should be favored by interdisciplinary, integrative research organizations working simultaneously in the analytical and synthetic dimensions of scientific knowledge. © The Author 2017.

Rural development and family planning behavior in Bangladesh Villages.
Alauddin, M
1979-01-01
Variarion in knowledge and usage of contraceptive methods was examined across Bangladesh villages. It was hypothesized that the variation can be explained by 3 sets of factors measured at the village level: development programs, family planning program efforts, and given environmental and socioeconomic conditions. The data were drawn from the Bangladesh Fertility Survey and the 1974 Bangladesh Population Census. The 3 sets of factors taken together explained a greater proportion of the variance in knowledge and contraceptive usage than each of the sets taken either singly or in paired combination. Knowledge of clinical contraceptive methods was found to be affected more by development programs than by either family planning or environmental and socioeconomic conditions. Despite the fact that both development and family planning variables have independent and about equal effects on ever use of contraception, each of them separately is not likely to produce as much contraceptive usage as would both of them jointly. In terms of policy, if both development and family planning programs are provided to the villages, the effect on fertility may be maximized.
Theorizing Race and Racism: Preliminary Reflections on the Medical Curriculum.
Braun, Lundy
2017-05-01
The current political economic crisis in the United States places in sharp relief the tensions and contradictions of racial capitalism as it manifests materially in health care and in knowledge-producing practices. Despite nearly two decades of investment in research on racial inequality in disease, inequality persists. While the reasons for persistence of inequality are manifold, little attention has been directed to the role of medical education. Importantly, medical education has failed to foster critical theorizing on race and racism to illuminate the often-invisible ways in which race and racism shape biomedical knowledge and clinical practice. Medical students across the nation are advocating for more critical anti-racist education that centers the perspectives and knowledge of marginalized communities. This Article examines the contemporary resurgence in explicit forms of white supremacy in light of growing student activism and research that privileges notions of innate differences between races. It calls for a theoretical framework that draws on Critical Race Theory and the Black Radical Tradition to interrogate epistemological practices and advocacy initiatives in medical education.
Postoperative self-efficacy and psychological morbidity in radical prostatectomy1
da Mata, Luciana Regina Ferreira; de Carvalho, Emilia Campos; Gomes, Cássia Regina Gontijo; da Silva, Ana Cristina; Pereira, Maria da Graça
2015-01-01
Objective: evaluate the general and perceived self-efficacy, psychological morbidity, and knowledge about postoperative care of patients submitted to radical prostatectomy. Identify the relationships between the variables and know the predictors of self-efficacy. Method: descriptive, cross-sectional study, conducted with 76 hospitalized men. The scales used were the General and Perceived Self-efficacy Scale and the Hospital Anxiety and Depression Scale, in addition to sociodemographic, clinical and knowledge questionnaires. Results: a negative relationship was found for self-efficacy in relation to anxiety and depression. Psychological morbidity was a significant predictor variable for self-efficacy. An active professional situation and the waiting time for surgery also proved to be relevant variables for anxiety and knowledge, respectively. Conclusion: participants had a good level of general and perceived self-efficacy and small percentage of depression. With these findings, it is possible to produce the profile of patients about their psychological needs after radical prostatectomy and, thus, allow the nursing professionals to act holistically, considering not only the need for care of physical nature, but also of psychosocial nature.

The NCI Genomic Data Commons as an engine for precision medicine.
Jensen, Mark A; Ferretti, Vincent; Grossman, Robert L; Staudt, Louis M
2017-07-27
The National Cancer Institute Genomic Data Commons (GDC) is an information system for storing, analyzing, and sharing genomic and clinical data from patients with cancer. The recent high-throughput sequencing of cancer genomes and transcriptomes has produced a big data problem that precludes many cancer biologists and oncologists from gleaning knowledge from these data regarding the nature of malignant processes and the relationship between tumor genomic profiles and treatment response. The GDC aims to democratize access to cancer genomic data and to foster the sharing of these data to promote precision medicine approaches to the diagnosis and treatment of cancer.
Pre-sporulation stages of Streptomyces differentiation: state-of-the-art and future perspectives.
Yagüe, Paula; López-García, Maria T; Rioseras, Beatriz; Sánchez, Jesús; Manteca, Angel

Streptomycetes comprise very important industrial bacteria, producing two-thirds of all clinically relevant secondary metabolites. They are mycelial microorganisms with complex developmental cycles that include programmed cell death (PCD) and sporulation. Industrial fermentations are usually performed in liquid cultures (large bioreactors), conditions in which Streptomyces strains generally do not sporulate, and it was traditionally assumed that there was no differentiation. In this work, we review the current knowledge on Streptomyces pre-sporulation stages of Streptomyces differentiation. © 2013 Federation of European Microbiological Societies.

The applied biochemistry of PEDF and implications for tissue homeostasis
BROADHEAD, MATTHEW L.; BECERRA, S. PATRICIA; CHOONG, PETER F. M.; DASS, CRISPIN R.
2012-01-01
Pigment epithelium-derived factor (PEDF) is an endogenously produced glycoprotein with a spectrum of biological roles across diverse pathologies. Recent research has focused on the biochemical properties of PEDF and its associated receptors. This review discusses the recent developments in PEDF biochemistry and how this new knowledge will help progress our understanding of PEDF as a molecular mediator for anti-angiogenesis and -tumorigenesis. Additionally, pathophysiological roles for PEDF in healing and tissue homeostasis are being revealed and our enhanced understanding of the interactions between PEDF and its receptors may yet prove useful in propelling PEDF towards clinical application.

We have developed a hand-held in vivo scanning device for use in the oral cavity. We produced, using this scanning device, in vivo OCT images of dental tissues in human volunteers. All the OCT images were analyzed for the presence of clinically relevant anatomical structures. The gingival margin, periodontal sulcus, and dento-enamel junction were visible in all the images. The cemento-enamel junction was discernible in 64% of the images and the alveolar bone presumptively identified for 71% of the images. These images represent, to our knowledge, the first in vivo OCT images of human dental tissue.

Antenatal care (ANC) is a key strategy to decreasing maternal mortality in low-resource settings. ANC clinics provide resources to improve nutrition and health knowledge and promote preventive health practices. We sought to compare the knowledge, attitude and practices (KAP) among women seeking and not-seeking ANC in rural Kenya. Data from a community-based cross-sectional survey conducted in Western Province, Kenya were used. Nutrition knowledge (NKS), health knowledge (HKS), attitude score (AS), and dietary diversity score (DDS) were constructed indices. χ2 test and Student's t-test were used to compare proportions and means, respectively, to assess the difference in KAP among pregnant women attending and not-attending ANC clinics. Multiple regression analyses were used to assess the impact of the number of ANC visits (none, <4, ≥4) on knowledge and practice scores, adjusting for maternal socio-demographic confounders, such as age, gestational age, education level and household wealth index. Among the 979 pregnant women in the survey, 59% had attended ANC clinics while 39% had not. The mean (±SD) NKS was 4.6 (1.9) out of 11, HKS was 6.2 (1.7) out of 12, DDS was 4.9 (1.4) out of 12, and AS was 7.4 (2.2) out of 10. Nutrition knowledge, attitudes, and DDS were not significantly different between ANC clinic attending and non-attending women. Among women who attended ANC clinics, 82.6% received malaria and/or antihelmintic treatment, compared to 29.6% of ANC clinic non-attendees. Higher number of ANC clinic visits and higher maternal education level were significantly positively associated with maternal health knowledge. Substantial opportunities exist for antenatal KAP improvement among women in Western Kenya, some of which could occur with greater ANC attendance. Further research is needed to understand multi-level factors that may affect maternal knowledge and practices.

The aim of this study was to investigate the associations between dental knowledge, the source of dental knowledge and oral health behavior in a group of students at a university in Japan. A total of 2,220 university students (1,276 males, 944 females) volunteered to undergo an oral examination and answer a questionnaire. The questionnaire assessed dental knowledge, the source of dental knowledge and oral health behavior (e.g., daily frequency of tooth brushing, use of dental floss and regular dental checkups). The odds ratio and 95% confidence interval for oral health behavior based on dental knowledge and source of dental knowledge were calculated using logistic regression models. Of the participants, 1,266 (57.0%) students obtained dental knowledge from dental clinics, followed by school (39.2%) and television (29.1%). Logistic regression analyses indicated that use of dental floss was significantly associated with source of dental knowledge from dental clinics (P = 0.006). Receiving regular dental checkups was significantly associated with source of dental knowledge; the positive source was dental clinic (P < 0.001) and the negative sources were school (P = 0.004) and television (P = 0.018). Dental clinic was the most common source of dental knowledge and associated with better oral health behavior among the Japanese university students in this study. PMID:28594914
Clinical Knowledge from Observational Studies: Everything You Wanted to Know but Were Afraid to Ask.

Well-done randomized trials provide accurate estimates of treatment effect by producing groups that are similar on all measures except for the intervention of interest. However, inferences of efficacy in tightly-controlled experimental settings may not translate into similar effectiveness in real-world settings. Observational studies generally enable inferences over a wider range of patient characteristics and evaluation of a broader range of outcomes over a longer period than randomized trials. However, clinicians are often reluctant to incorporate the findings of observational studies into clinical practice. Reason for uncertainty regarding observational studies include a lack of familiarity with observational research methods, occasional disagreements between results of observational studies and randomized trials, the perceived risk of spurious results from systematic bias, and prior teaching that randomized trials are the most reliable source of medical evidence. We propose that a better understanding of observational research will enhance clinicians' ability to distinguish reliable observational studies from those that are subjected to biases and, therefore, provide more confidence to apply observational research results into clinical practice when appropriate. Herein, we explain why observational studies may be perceived as less conclusive than randomized trials, address situations in which observational research and randomized trials produced different findings, and provide information on observational study design so that quality can be evaluated. We conclude that observational research is a valuable source of medical evidence and that clinical action is strongest when supported by both high quality observational studies and randomized trials.

Knowledge generated by site representatives through their participation in clinical trials is valuable for testing new products in use and obtaining final market approval. The leverage of this important knowledge is however challenged as the former direct relationships between in-house staff in the industry and site representatives are changing. The process of clinical trials has increased in complexity over the years, resulting in additional management layers. Besides an increase in internal management layers, sponsors often also outsource various tasks related to clinical trials to a CRO (Contract Research Organization) and thereby adding another link in the relationships between site and sponsor. These changes are intended to optimize the time-consuming and costly trial phases; however, there is a need to study whether valuable knowledge and experience is compromised in the process. Limited research exists on the full range of clinical practice insights obtained by investigators during and after clinical trials and how well these insights are transferred to study sponsors. This study explores the important knowledge-transfer processes between sites and sponsors and to what extent sites' knowledge gained in clinical trials is utilized by the industry. Responses from 451 global investigative site representatives are included in the study. The analysis of the extensive dataset reveals that the current processes of collaboration between sites and the industry restrict the leverage of valuable knowledge gained by physicians in the process of clinical trials. These restrictions to knowledge-transfer between site and sponsor are further challenged if CRO partners are integrated in the trial process. Copyright © 2013 Elsevier Inc. All rights reserved.

Heart disease is a leading cause of morbidity and mortality in men and women. Our understanding of heart disease stems chiefly from clinical trials on men, but key features of the disease differ in women. This article reports findings from the first Canadian national survey of women that focuses on knowledge, perceptions, and lifestyle related to heart health. A cross-country survey using an adaptation of an instrument used in the United States was undertaken in spring of 2013. Based on online (208) and telephone (1446) responses from a randomly selected sample of women aged 25 or older, a total sample of 1654 weighted percentage estimates were produced. The overall response rate was 12.5%. Just under half of women were able to name smoking as a risk factor of heart disease, and less than one quarter named hypertension or high cholesterol. Fewer than half of women knew the major symptoms of heart disease. Most women prefer to receive information on heart health from their doctor, but only slightly more than half report that their doctor includes discussion of prevention and lifestyle during clinical consultations. Most women lack knowledge of heart disease symptoms and risk factors, and significant proportions are unaware of their own risk status. The findings underscore the opportunity for patient education and intervention regarding risk and prevention of heart disease. Copyright © 2014 Canadian Cardiovascular Society.

Personalized medicine, the ability to tailor diagnostic and treatment decisions for individual patients, is seen as the evolution of modern medicine. We characterize here the informatics resources available today or envisioned in the near future that can support clinical interpretation of genomic test results. We assume a clinical sequencing scenario (germline whole-exome sequencing) in which a clinical specialist, such as an endocrinologist, needs to tailor patient management decisions within his or her specialty (targeted findings) but relies on a genetic counselor to interpret off-target incidental findings. We characterize the genomic input data and list various types of knowledge bases that provide genomic knowledge for generating clinical decision support. We highlight the need for patient-level databases with detailed lifelong phenotype content in addition to genotype data and provide a list of recommendations for personalized medicine knowledge bases and databases. We conclude that no single knowledge base can currently support all aspects of personalized recommendations and that consolidation of several current resources into larger, more dynamic and collaborative knowledge bases may offer a future path forward.

The advent of the knowledge-based economy has underlined the importance of intellectual capital that is possessed by knowledge intensive organizations. Three general observations of knowledge intensive work produced by actors working in such organizations served as the basis for the initiation of this research. First, knowledge intensive tasks become increasingly complex. Second, actors that perform such tasks experience an increase in cognitive load. Third, the desired quality of task performance and the produced task results are at stake due to the aforementioned two developments. In this research we investigate how supply and demand of intangible assets such as knowledge, cognitive characteristics, and quality factors can be matched based on market mechanisms.

Given that clinicians presented with identical clinical information will act in different ways, there is a need to introduce into routine clinical practice methods and tools to support the scientific homogeneity and accountability of healthcare decisions and actions. The benefits expected from such action include an overall reduction in cost, improved quality of care, patient and public opinion satisfaction. Computer-based medical data processing has yielded methods and tools for managing the task away from the hospital management level and closer to the desired disease and patient management level. To this end, advanced applications of information and disease process modelling technologies have already demonstrated an ability to significantly augment clinical decision making as a by-product. The wide-spread acceptance of evidence-based medicine as the basis of cost-conscious and concurrently quality-wise accountable clinical practice suffices as evidence supporting this claim. Electronic libraries are one-step towards an online status of this key health-care delivery quality control environment. Nonetheless, to date, the underlying information and knowledge management technologies have failed to be integrated into any form of pragmatic or marketable online and real-time clinical decision making tool. One of the main obstacles that needs to be overcome is the development of systems that treat both information and knowledge as clinical objects with same modelling requirements. This paper describes the development of such a system in the form of an intelligent clinical information management system: a system which at the most fundamental level of clinical decision support facilitates both the organised acquisition of clinical information and knowledge and provides a test-bed for the development and evaluation of knowledge-based decision support functions.

Purpose One of the major issues faced by academic health science centers (AHSCs) is the need for mechanisms to foster the integration of research, clinical, and educational activities to achieve the vision of evidence-informed decision making (EIDM) and optimal client care. The paper aims to discuss this issue. Design/methodology/approach This paper synthesizes literature on organizational learning and collaboration, evidence-informed organizational decision making, and learning-based organizations to derive insights concerning the nature of effective workplace learning in AHSCs. Findings An evidence-informed model of collaborative workplace learning is proposed to aid the alignment of research, clinical, and educational functions in AHSCs. The model articulates relationships among AHSC academic functions and sub-functions, cross-functional activities, and collaborative learning processes, emphasizing the importance of cross-functional activities in enhancing collaborative learning processes and optimizing EIDM and client care. Cross-functional activities involving clinicians, researchers, and educators are hypothesized to be a primary vehicle for integration, supported by a learning-oriented workplace culture. These activities are distinct from interprofessional teams, which are clinical in nature. Four collaborative learning processes are specified that are enhanced in cross-functional activities or teamwork: co-constructing meaning, co-learning, co-producing knowledge, and co-using knowledge. Practical implications The model provides an aspirational vision and insight into the importance of cross-functional activities in enhancing workplace learning. The paper discusses the conceptual and empirical basis to the model, its contributions and limitations, and implications for AHSCs. Originality/value The model's potential utility for health care is discussed, with implications for organizational culture and the promotion of cross-functional activities.

Background: Testing coagulation factor activities requires that multiple dilutions be assayed and analyzed to produce a single result. The slope of the line created by plotting measured factor concentration against sample dilution is evaluated to discern the presence of inhibitors giving rise to nonparallelism. Moreover, samples producing results on initial dilution falling outside the analytic measurement range of the assay must be tested at additional dilutions to produce reportable results. Methods: The complexity of this process has motivated a large clinical reference laboratory to develop advanced computer algorithms with automated reflex testing rules to complete coagulation factor analysis. A method was developed for autoverification of coagulation factor activity using expert rules developed with on an off the shelf commercially available data manager system integrated into an automated coagulation platform. Results: Here, we present an approach allowing for the autoverification and reporting of factor activity results with greatly diminished technologist effort. Conclusions: To the best of our knowledge, this is the first report of its kind providing a detailed procedure for implementation of autoverification expert rules as applied to coagulation factor activity testing. Advantages of this system include ease of training for new operators, minimization of technologist time spent, reduction of staff fatigue, minimization of unnecessary reflex tests, optimization of turnaround time, and assurance of the consistency of the testing and reporting process.

The InterMed Collaboratory is an interdisciplinary project involving six participating medical institutions. There are two broad mandates for the effort. The first is to further the development, sharing, and demonstration of numerous software and system components, data sets, procedures and tools that will facilitate the collaborations and support the application goals of these projects. The second is to provide a distributed suite of clinical applications, guidelines, and knowledge-bases for clinical, educational, and administrative purposes. To define the interactions among the components, datasets, procedures, and tools that we are producing and sharing, we have identified a model composed of seven tiers, each of which supports the levels above it. In this paper we briefly describe those tiers and the nature of the collaborative process with which we have experimented. PMID:8947641

Assessment of the knowledge and application as well as perceived utility by doctors of clinical governance tools in order to explore their impact on clinical units' performance measured through mortality rates and efficiency indicators. This research is a cross-sectional study with a deterministic record-linkage procedure. The sample includes n = 1250 doctors (n = 249 chiefs of clinical units; n = 1001 physicians) working in six public hospitals located in the Emilia-Romagna Region in Italy. Survey instruments include a checklist and a research-made questionnaire which were used for data collection about doctors' knowledge and application as well as perceived utility of clinical governance tools. The analysis was based on clinical units' performance indicators which include patients' mortality, extra-region active mobility rate, average hospital stay, bed occupancy, rotation and turnover rates, and the comparative performance index as efficiency indicators. The clinical governance tools are known and applied differently in all the considered clinical units. Significant differences emerged between roles and organizational levels at which the medical leadership is carried out. The levels of knowledge and application of clinical governance practices are correlated with the clinical units' efficiency indicators (bed occupancy rate, bed turnover interval, and extra-region mobility). These multiple linear regression analyses highlighted that the clinical governance knowledge and application is correlated with clinical units' mortality rates (odds ratio, -8.677; 95% confidence interval, -16.654, -0.700). The knowledge and application, as well as perceived utility by medical professionals of clinical governance tools, are associated with the mortality rates of their units and with some efficiency indicators. However, the medical frontline staff seems to not consider homogeneously useful the clinical governance tools application on its own clinical practice.

Patient satisfaction is regarded as an integral component of the quality of medical care. Therefore, as part of an ongoing process of outcome assessment, we analysed levels of satisfaction of care among patients and parents in our diabetes clinic and its relationship to short-term metabolic control outcome, diabetes knowledge and health-related quality of life (HRQOL). In 2004, parents and their children aged 5-18 years attending the Royal Children's Hospital (RCH) diabetes clinic completed questionnaires reporting their satisfaction with care provided, HRQOL and diabetes knowledge. Concurrent HbA(1c) levels were also recorded. The reporting profile was 83 patients, 24 fathers and 110 mothers. Generally, both patients and parents were satisfied with diabetes care provided at our tertiary centre. Satisfaction of care was not associated with the clinical outcome of metabolic control (measured by HbA(1c) levels), diabetes knowledge or HRQOL measures. Most patients and their parents in the RCH diabetes clinic appear generally satisfied with their diabetes care. The degree of satisfaction of care cannot be presumed according to clinical outcome, diabetes knowledge or HRQOL measures.

Human pluripotent stem cells have made a remarkable impact on science, technology and medicine by providing a potentially unlimited source of human cells for basic research and clinical applications. In recent years, knowledge gained from the study of human embryonic stem cells and mammalian somatic cell reprogramming has led to the routine production of human induced pluripotent stem cells (hiPSCs) in laboratories worldwide. hiPSCs show promise for use in transplantation, high throughput drug screening, "disease-in-a-dish" modeling, disease gene discovery, and gene therapy testing. This review will focus on the first application, beginning with a discussion of methods for producing retinal lineage cells that are lost in inherited and acquired forms of retinal degenerative disease. The selection of appropriate hiPSC-derived donor cell type(s) for transplantation will be discussed, as will the caveats and prerequisite steps to formulating a clinical Good Manufacturing Practice (cGMP) product for clinical trials.

Giardia duodenalis is one of the most prevalent enteroparasites in children. This parasite produces several clinical manifestations. The aim of this study was to determine the prevalence of genotypes of G. duodenalis causing infection in a region of southeastern Mexico. G. duodenalis cysts were isolated (33/429) from stool samples of children and molecular genotyping was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis, targeting the triosephosphate isomerase ( tpi ) and glutamate dehydrogenase ( gdh ) genes. The tpi gene was amplified in all of the cyst samples, either for assemblage A (27 samples) or assemblage B (6 samples). RFLP analysis classified the 27 tpi -A amplicons in assemblage A, subgenotype I. Samples classified as assemblage B were further analysed using PCR-RFLP of the gdh gene and identified as assemblage B, subgenotype III. To our knowledge, this is the first report of assemblage B of G. duodenalis in human clinical samples from Mexico. PMID:24676655

A wealth of clinical data exists in clinical documents in the form of electronic health records (EHRs). This data can be used for developing knowledge-based recommendation systems that can assist clinicians in clinical decision making and education. One of the big hurdles in developing such systems is the lack of automated mechanisms for knowledge acquisition to enable and educate clinicians in informed decision making. An automated knowledge acquisition methodology with a comprehensible knowledge model for cancer treatment (CKM-CT) is proposed. With the CKM-CT, clinical data are acquired automatically from documents. Quality of data is ensured by correcting errors and transforming various formats into a standard data format. Data preprocessing involves dimensionality reduction and missing value imputation. Predictive algorithm selection is performed on the basis of the ranking score of the weighted sum model. The knowledge builder prepares knowledge for knowledge-based services: clinical decisions and education support. Data is acquired from 13,788 head and neck cancer (HNC) documents for 3447 patients, including 1526 patients of the oral cavity site. In the data quality task, 160 staging values are corrected. In the preprocessing task, 20 attributes and 106 records are eliminated from the dataset. The Classification and Regression Trees (CRT) algorithm is selected and provides 69.0% classification accuracy in predicting HNC treatment plans, consisting of 11 decision paths that yield 11 decision rules. Our proposed methodology, CKM-CT, is helpful to find hidden knowledge in clinical documents. In CKM-CT, the prediction models are developed to assist and educate clinicians for informed decision making. The proposed methodology is generalizable to apply to data of other domains such as breast cancer with a similar objective to assist clinicians in decision making and education.

In an era of expanding health sectors and rising costs, doctors are expected to have a working knowledge of health economics to better use resources and improve outcomes and quality of health care. This article recognizes the dearth of knowledge and application of economic analyses in medical education and clinical practice in Saudi Arabia. In particular, it highlights the desirability of knowledge of health economics in ensuring certain competencies in medical education and the rationale for inviting doctors to apply knowledge of economics in Saudi Arabia. In addition, the article discusses challenges that hinder integrating health economics into clinical practice. Furthermore, the article typifies some of the important economic phenomena that physicians need to discern. Besides, the article provides implications for incorporating economic analysis into medical education and clinical practice in Saudi Arabia. Finally, the article concludes by demonstrating how health economics can enhance doctors' knowledge and recommends the country to move towards integrating health economics into medical education and clinical practice for best practice.

While the results of clinical research are clearly valuable in the care of critically ill patients, the limitations of such information and the role of other forms of medical knowledge for clinical decision making have not been carefully examined. The leadership of three large professional societies representing critical care practitioners convened a diverse group representing a wide variety of views regarding the role of clinical research results in clinical practice to develop a document to serve as a basis for agreement and a framework for ongoing discussion. Consensus was reached on several issues. While the results of rigorous clinical research are important in arriving at the best course of action for an individual critically ill patient, other forms of medical knowledge, including clinical experience and pathophysiologic reasoning, remain essential. No single source of knowledge is sufficient to guide clinical decisions, nor does one kind of knowledge always take precedence over others. Clinicians will find clinical research compelling for a variety of reasons that go beyond study design. While clinical practice guidelines and protocols based upon clinical research may improve care and decrease variability in practice, clinicians must be able to understand and articulate the rationale as to why a particular protocol or guideline is used or why an alternative approach is taken. Making this clinical reasoning explicit is necessary to understand practice variability. Understanding the strengths and weaknesses of different kinds of medical knowledge for clinical decision making and factors beyond study design that make clinical research compelling to clinicians can provide a framework for understanding the role of clinical research in practice.

The College of Medicine of the University of Ibadan recently revised its MBBS and BDS curricula to a competency-based medical education method of instruction. This paper reports the process of revising the methods of instruction and assessment in the core basic medical sciences directed at producing medical and dental graduates with a sound knowledge of the subjects sufficient for medical and dental practice and for future postgraduate efforts in the field or related disciplines. The health needs of the community and views of stakeholders in the Ibadan medical and dental schools were determined, and the “old” curriculum was reviewed. This process was directed at identifying the strengths and weaknesses of the old curricula and the newer competences required for modern-day medical/dental practice. The admission criteria and processes and the learning methods of the students were also studied. At the end of the review, an integrated, system-based, community-oriented, person-centered, and competency-driven curriculum was produced and approved for implementation. Four sets of students have been admitted into the curriculum. There have been challenges to the implementation process, but these have been overcome by continuous faculty development and reorientation programs for the nonteaching staff and students. Two sets of students have crossed over to the clinical school, and the consensus among the clinical teachers is that their knowledge and application of the basic medical sciences are satisfactory. The Ibadan medical and dental schools are implementing their competency-based medical education curricula successfully. The modifications to the teaching and assessment of the core basic medical science subjects have resulted in improved learning and performance at the final examinations. PMID:27486351

The glial cell line-derived neurotrophic factor (GDNF) is a well-established trophic agent for dopaminergic (DA) neurons in vitro and in vivo. GDNF is necessary for maintenance of neuronal morphological and neurochemical phenotype and protects DA neurons from toxic damage. Numerous studies on animal models of Parkinson’s disease (PD) have reported beneficial effects of GDNF on nigrostriatal DA neuron survival. However, translation of these observations to the clinical setting has been hampered so far by side effects associated with the chronic continuous intra-striatal infusion of recombinant GDNF. In addition, double blind and placebo-controlled clinical trials have not reported any clinically relevant effect of GDNF on PD patients. In the past few years, experiments with conditional Gdnf knockout mice have suggested that GDNF is necessary for maintenance of DA neurons in adulthood. In parallel, new methodologies for exogenous GDNF delivery have been developed. Recently, it has been shown that a small population of scattered, electrically interconnected, parvalbumin positive (PV+) GABAergic interneurons is responsible for most of the GDNF produced in the rodent striatum. In addition, cholinergic striatal interneurons appear to be also involved in the modulation of striatal GDNF. In this review, we summarize current knowledge on brain GDNF delivery, homeostasis, and its effects on nigrostriatal DA neurons. Special attention is paid to the therapeutic potential of endogenous GDNF stimulation in PD. PMID:25762899

Whooping cough is a re-emerging infection in the world and Latin America. It was considered relevant to investigate the clinical and epidemiological profile of Bordetella spp. and Bordetella pertussis infection in Córdoba province, Argentina; evaluating, at the same time, the co-infection with virus producing respiratory infections that may be confused with whooping cough. All whooping cough suspected cases were studied by Polimerase Chain Reaction, amplifying the repeated insertion sequence (IS) 481 and the promoter gene encoding pertussis toxin, between 2011 and 2013. The data were obtained from the clinical and epidemiological records. From 2,588 whooping cough suspected cases, 11.59% was infected by Bordetella spp. and 9.16% was confirmed as Bordetella pertussis infection. The rate of infection was 7.22 and 1.84 per 100,000 for 2011 and 2012, respectively. The infection presented a seasonal tendency and it was mainly found on the group of children between 13 and 24 months old. The co-infection with virus producing respiratory infections, were uncommon. Paroxysmal cough, cyanosis and/or vomiting were predictors of the infection for Bordetella pertussis. To deal with the re-emergence of whooping cough is important the knowledge of the regional epidemiological situation. This paper shows the situation of these infections in the regional clinical and epidemiological context, and makes the information available for health decision-making.

Tissue engineered tracheae have been successfully implanted to treat a small number of patients on compassionate grounds. The treatment has not become mainstream due to the time taken to produce the scaffold and the resultant financial costs. We have developed a method for decellularization (DC) based on vacuum technology, which when combined with an enzyme/detergent protocol significantly reduces the time required to create clinically suitable scaffolds. We have applied this technology to prepare porcine tracheal scaffolds and compared the results to scaffolds produced under normal atmospheric pressures. The principal outcome measures were the reduction in time (9 days to prepare the scaffold) followed by a reduction in residual DNA levels (DC no-vac: 137.8±48.82 ng/mg vs. DC vac 36.83±18.45 ng/mg, p<0.05.). Our approach did not impact on the collagen or glycosaminoglycan content or on the biomechanical properties of the scaffolds. We applied the vacuum technology to human tracheae, which, when implanted in vivo showed no significant adverse immunological response. The addition of a vacuum to a conventional decellularization protocol significantly reduces production time, whilst providing a suitable scaffold. This increases clinical utility and lowers production costs. To our knowledge this is the first time that vacuum assisted decellularization has been explored. Copyright © 2015 John Wiley & Sons, Ltd.

Guillain-Barré syndrome (GBS) is an immune-mediated inflammatory disorder of the peripheral nervous system (PNS). Experimental autoimmune neuritis (EAN) is a useful animal model for studying GBS. Currently, GBS remains a life-threatening disorder and more effective therapeutic strategies are in urgent need. Accumulating evidence has revealed that T helper (Th) 17 cells and their cytokines are pathogenic in GBS/EAN. Drugs attenuated clinical signs of GBS/EAN, in part, by decreasing Th17 cells or IL-17A. Th17 cells and their cytokines might be potential therapeutic targets. Approaches targeting Th17 cells or their cytokines are in development in treating Th17 cells-involved disorders. In this review, we summarize the up-to-date knowledge on roles of Th17 cells and their cytokines in GBS/EAN, as well potential approaches targeting Th17 cells and their cytokines as clinical applications. As Th17 cells produce different sets of pro-inflammatory cytokines and Th17-related cytokines are not exclusively produced by Th17 cells, targeting Th17 cell development may be superior to blocking a single Th17 cytokine to treat Th17 cells-involved disorders. Considering the essential role of retinoic acid-related orphan receptor γT (RORγT) and IL-23 in Th17 cell development, RORγT inhibitors or IL-23 antagonists may provide better clinical efficacy in treating GBS/EAN.
Appearance of colonies of Prototheca on CHROMagar Candida medium.

The microorganisms capable of producing opportunist infections include the yeast-like organisms of the genus Candida, and the unicellular algae of the genus Prototheca, which share common features and can, therefore, lead to confusion. Their colonies are almost identical and they grow in the same culture media used routinely in mycology. CHROMagar Candida is a new chromogenic differential isolation medium that facilitates the presumptive differentiation of some of the most clinically important yeast-like organisms. To our knowledge, the use of CHROMagar Candida with Prototheca spp. has not been reported in the literature. This report describes the growth of 151 strains of Prototheca on CHROMagar Candida compared to the growth of a total of 326 well-characterized yeast organisms of the genera Candida, Cryptococcus, Trichosporon, Geotrichum, and Saccharomyces. It is clinically relevant to note that algae of the genus Prototheca (P. wickerhamii, P. zopfii, and P. stagnora) and of the genus Candida parapsilosis produced similar cream-colored colonies on CHROMagar Candida medium. Based on their growth on CHROMagar, a new species of Candida is described, C. zeylanoides, which has blue-green colonies. The colonies of two species of Trichosporon are also differentiated: the blue-green colonies of T. beigelii and the pink colonies of T. capitatum.
Animal models of Parkinson's disease: limits and relevance to neuroprotection studies.
Bezard, Erwan; Yue, Zhenyu; Kirik, Deniz; Spillantini, Maria Grazia

Over the last two decades, significant strides has been made toward acquiring a better knowledge of both the etiology and pathogenesis of Parkinson's disease (PD). Experimental models are of paramount importance to obtain greater insights into the pathogenesis of the disease. Thus far, neurotoxin-based animal models have been the most popular tools employed to produce selective neuronal death in both in vitro and in vivo systems. These models have been commonly referred to as the pathogenic models. The current trend in modeling PD revolves around what can be called the disease gene-based models or etiologic models. The value of utilizing multiple models with a different mechanism of insult rests on the premise that dopamine-producing neurons die by stereotyped cascades that can be activated by a range of insults, from neurotoxins to downregulation and overexpression of disease-related genes. In this position article, we present the relevance of both pathogenic and etiologic models as well as the concept of clinically relevant designs that, we argue, should be utilized in the preclinical development phase of new neuroprotective therapies before embarking into clinical trials.

Friedreich's ataxia (FA) is the most frequent hereditary ataxia syndrome, while painful muscle spasms and spasticity have been reported in 11-15% of FA patients. This report describes the successful management of painful spasms in a 65-year-old woman with FA via intrathecal baclofen (ITB) therapy following unsuccessful medical treatments. To our knowledge, this is the third reported case in the literature. Unfortunately, the pathophysiological characteristics of muscle spasms in FA are not well explored and understood while the therapeutic mechanisms of the different treatments are rather vague. Taking into consideration the suggested spinal atrophy in FA, the clinical resemblance of FA and chronic spinal injury muscle spasms, together with the rapid ITB therapy effectiveness in alleviating FA muscle spasms, we attempted to suggest a putative pathophysiological mechanism acting at the spinal level and possibly explained by the presence of independent spinal locomotor systems producing muscle spasms. Specifically, overexcitement of these centers, due to loss of normal regulation from upper CNS levels, may result in the uncontrolled firing of secondary motor neurons and may be the key to producing muscle spasms. However, further research under experimental and clinical settings seems to be necessary. © 2018 S. Karger AG, Basel.

Bisphosphonate-induced osteonecrosis of the jaw (BONJ) represents a growing concern for dentists and patients, in that it may alter clinical care. This study assesses the knowledge and perceptions of practicing dentists in relation to the risk of BONJ and how their knowledge and perceptions influence their decisions when developing treatment plans. For this study, a sample of dentists (n = 93) in South Texas completed a 38-item survey about BONJ knowledge and perception and their current clinical practices for patients undergoing bisphosphonate therapy. Knowledge score groupings reflected differences between low-knowledge and high-knowledge dentists in terms of their behavior concerning medical history, alternative treatments offered, and routine blood testing for patients on bisphosphonate therapy.

The author's reflections on knowledge transfer/translation highlight the importance of the circular process between science and practice knowledge, leading to the notion of "knowledge exchange." She addresses the dilemmas of translating knowledge into clinical practice by describing her academic contributions to knowledge exchange within Family Systems Nursing (FSN). Teaching and research strategies are offered that address the circularity between science and practice knowledge. The evolution of 20 years of teaching, research, and clinical experience has resulted in the recent creation of a Center of Excellence in Family Nursing at the University of Montreal. The three main objectives of the Center uniquely focus on knowledge exchange by providing (a) a training context for skill development for nurses specializing in FSN, (b) a research milieu for knowledge "creation" and knowledge "in action" studies to further advance the practice of FSN, and (c) a family healing setting to support families who experience difficulty coping with health issues.

The Art of Clinical Supervision program was developed, implemented, and evaluated to determine nursing staff knowledge of and attitudes toward nursing students and the clinical supervision thereof. A key point of the program was the inclusion of strategies to promote one's attitude toward working with students. A mixed methods approach of surveys, online reflections, and interviews was used to determine the program's effect. The findings highlighted a positive impact on participants' self-knowledge and attitudes toward students and student clinical supervision.
Integration of a knowledge-based system and a clinical documentation system via a data dictionary.
Eich, H P; Ohmann, C; Keim, E; Lang, K
1997-01-01
This paper describes the design and realisation of a knowledge-based system and a clinical documentation system linked via a data dictionary. The software was developed as a shell with object oriented methods and C++ for IBM-compatible PC's and WINDOWS 3.1/95. The data dictionary covers terminology and document objects with relations to external classifications. It controls the terminology in the documentation program with form-based entry of clinical documents and in the knowledge-based system with scores and rules. The software was applied to the clinical field of acute abdominal pain by implementing a data dictionary with 580 terminology objects, 501 document objects, and 2136 links; a documentation module with 8 clinical documents and a knowledge-based system with 10 scores and 7 sets of rules.

The goal of the scientist-practitioner (S-P) training model is to produce clinical psychologists equipped to integrate and utilize both science and practice in the clinical and research domains. However, much has been written regarding the possible shortcomings of S-P training and whether clinical psychology graduate students are actually gaining the knowledge and skills to integrate science and practice during graduate training and beyond (Chang, Lee, & Hargreaves, 2008; Gelso, 2006; Merlo, Collins, & Bernstein, 2008; Phillips, 1993). As such, the present study assessed ratings of satisfaction, perception of ability, and use of the S-P training model within 653 clinical psychology graduate students enrolled in programs that are members of the Council of University Directors of Clinical Psychology. Findings suggest that students are consistently trained in the integration of science and practice and have confidence in their abilities to apply the S-P integration to research and clinical work. However, despite understanding the ways in which science can influence practice, over one third of students reported that they rarely use science-based decisions when informing clients of the clinical services they will be providing. The implications of these results support the need for a more detailed evaluation of clinical psychology graduate students as well as the use of research-informed practice and the process of providing clients with information they need to make informed choices about treatment. © 2012 Wiley Periodicals, Inc.
Formal Representations of Eligibility Criteria: A Literature Review
Weng, Chunhua; Tu, Samson W.; Sim, Ida; Richesson, Rachel
2010-01-01
Standards-based, computable knowledge representations for eligibility criteria are increasingly needed to provide computer-based decision support for automated research participant screening, clinical evidence application, and clinical research knowledge management. We surveyed the literature and identified five aspects of eligibility criteria knowledge representations that contribute to the various research and clinical applications: the intended use of computable eligibility criteria, the classification of eligibility criteria, the expression language for representing eligibility rules, the encoding of eligibility concepts, and the modeling of patient data. We consider three of them (expression language, codification of eligibility concepts, and patient data modeling), to be essential constructs of a formal knowledge representation for eligibility criteria. The requirements for each of the three knowledge constructs vary for different use cases, which therefore should inform the development and choice of the constructs toward cost-effective knowledge representation efforts. We discuss the implications of our findings for standardization efforts toward sharable knowledge representation of eligibility criteria. PMID:20034594
Knowledge about anti-tuberculosis treatment among nurses at tuberculosis clinics.
Yükseltürk, Neriman; Dinç, Leyla
2013-02-01
Nurses are primary responsible for Direct Observation Therapy Strategy and administration of anti-tuberculosis (TB) medications. Lack of knowledge might result with medication errors and ineffective TB control. The purpose of this study was to assess knowledge of nurses about anti-TB treatment. A descriptive cross-sectional study was conducted in Turkey with 208 nurses employed at TB and lung disease clinics of health-care settings in Ankara. Data were collected through a questionnaire, which included questions about demographics and a knowledge test with true-false questions related to TB treatment. Overall scores were high with a mean score of 18.5 out of 24, but there was knowledge deficiency in effects and side-effects of anti-TB drugs. Knowledge is foundational for any practice and for TB control. Clinical experience and continuing education after graduation influence the level of knowledge. © 2013 Wiley Publishing Asia Pty Ltd.
Medical data mining: knowledge discovery in a clinical data warehouse.

Clinical databases have accumulated large quantities of information about patients and their medical conditions. Relationships and patterns within this data could provide new medical knowledge. Unfortunately, few methodologies have been developed and applied to discover this hidden knowledge. In this study, the techniques of data mining (also known as Knowledge Discovery in Databases) were used to search for relationships in a large clinical database. Specifically, data accumulated on 3,902 obstetrical patients were evaluated for factors potentially contributing to preterm birth using exploratory factor analysis. Three factors were identified by the investigators for further exploration. This paper describes the processes involved in mining a clinical database including data warehousing, data query and cleaning, and data analysis. PMID:9357597
Medical teachers conceptualize a distinctive form of clinical knowledge.
Barrett, J; Yates, L; McColl, G
2015-05-01
For over four decades, there have been efforts to specify the types of knowledge that medical students need, how that knowledge is acquired and how its constituent parts are related. It is one of the areas of continuing concern underlying medical education reform. Despite their importance to medical students' learning and development, the perspectives of medical teachers in hospitals are not always considered in such discourse. This study sought to generate an understanding of these teachers' values, perspectives and approaches by listening to them and seeing them in their everyday teaching work, finding and understanding the meanings they bring to the work of medical teaching in hospitals. In interviews, all of the teachers talked more about the optimal forms of knowledge that are important for students than they talked about the form of the teaching itself. Many revealed to students what knowledge they do and do not value. They had a particular way of thinking about clinical knowledge as existing in the people and the places in which the teaching and the clinical practice happen, and represented this as 'real' knowledge. By implication, there is other knowledge in medical education or in students' heads that is not real and needs to be transformed. Their values, practices and passions add texture and vitality to existing ways of thinking about the characteristics of clinical knowledge, how it is depicted in the discourse and the curriculum and how it is more dynamically related to other knowledge than is suggested in traditional conceptualizations of knowledge relationships.
[Clinical research XXIV. From clinical judgment to ethics in research on humans].
Pérez-Rodríguez, Marcela; Palacios-Cruz, Lino; Rivas-Ruiz, Rodolfo; Talavera, Juan O

Bioethics in research is an essential part of the structured review process of an article and it is based on three fundamental principles: respect for persons, beneficence and justice. In addition to not providing valid knowledge, a research with inadequate design, execution and statistical analysis is not ethical either, since these methodological deficiencies will produce information that will not be useful and, therefore, the risks that the participants were exposed to will have been in vain. Beyond scientific validity, there are other aspects that outline if an investigation is ethical, such as the clinical and social value of a study, a fair selection of participants, favorable risk-benefit balance, an independent review, the informed consent and respect for participants and potential participants. Throughout the article here presented, the documents that profile the behavior of investigators to protect the participants, such as the Declaration of Helsinki, the national regulations that rule us and the differences between research without risk, with minimal risk and with greater than minimal risk are discussed. That like in daily life, behavior in research involving human participants must be self-regulated, ie, people with knowledge of the existence of the law discover that the man is outside the realm of nature where work is done under the necessity of natural causality, and falls within the scope of the will; only if the man is free to decide their actions may be a law regulating their action.

Knowledge in the era of Omics and Big Data has been increasingly conceptualized as a public good. Sharing of de-identified patient data has been advocated as a means to increase confidence and public trust in the results of clinical trials. On the other hand, research has shown that the current research and development model of the biopharmaceutical industry has reached its innovation capacity. In response to that, the biopharmaceutical industry has adopted open innovation practices, with sharing of clinical trial data being among the most interesting ones. However, due to the free rider problem, clinical trial data sharing among biopharmaceutical companies could undermine their innovativeness. Based on the theory of public goods, we have developed a commons arrangement and devised a model, which enables secure and fair clinical trial data sharing over a Virtual Knowledge Bank based on a web platform. Our model uses data as a virtual currency and treats knowledge as a club good. Fair sharing of clinical trial data over the Virtual Knowledge Bank has positive effects on the innovation capacity of the biopharmaceutical industry without compromising the intellectual rights, proprietary interests and competitiveness of the latter. The Virtual Knowledge Bank is a sustainable and self-expanding model for secure and fair clinical trial data sharing that allows for sharing of clinical trial data, while at the same time it increases the innovation capacity of the biopharmaceutical industry. © 2016 S.

One of the greatest challenges facing biomedical research is the integration and sharing of vast amounts of information, not only for individual researchers, but also for the community at large. Agent Based Modeling (ABM) can provide a means of addressing this challenge via a unifying translational architecture for dynamic knowledge representation. This paper presents a series of linked ABMs representing multiple levels of biological organization. They are intended to translate the knowledge derived from in vitro models of acute inflammation to clinically relevant phenomenon such as multiple organ failure. ABM development followed a sequence starting with relatively direct translation from in-vitro derived rules into a cell-as-agent level ABM, leading on to concatenated ABMs into multi-tissue models, eventually resulting in topologically linked aggregate multi-tissue ABMs modeling organ-organ crosstalk. As an underlying design principle organs were considered to be functionally composed of an epithelial surface, which determined organ integrity, and an endothelial/blood interface, representing the reaction surface for the initiation and propagation of inflammation. The development of the epithelial ABM derived from an in-vitro model of gut epithelial permeability is described. Next, the epithelial ABM was concatenated with the endothelial/inflammatory cell ABM to produce an organ model of the gut. This model was validated against in-vivo models of the inflammatory response of the gut to ischemia. Finally, the gut ABM was linked to a similarly constructed pulmonary ABM to simulate the gut-pulmonary axis in the pathogenesis of multiple organ failure. The behavior of this model was validated against in-vivo and clinical observations on the cross-talk between these two organ systems. A series of ABMs are presented extending from the level of intracellular mechanism to clinically observed behavior in the intensive care setting. The ABMs all utilize cell-level agents that encapsulate specific mechanistic knowledge extracted from in vitro experiments. The execution of the ABMs results in a dynamic representation of the multi-scale conceptual models derived from those experiments. These models represent a qualitative means of integrating basic scientific information on acute inflammation in a multi-scale, modular architecture as a means of conceptual model verification that can potentially be used to concatenate, communicate and advance community-wide knowledge.

Rigor in clinical knowledge representation is necessary foundation for meaningful interoperability, exchange and reuse of electronic health record (EHR) data. It is critical for clinicians to understand principles and implications of using clinical standards for knowledge representation within EHRs. To educate clinicians and students about knowledge representation and to evaluate their success of applying the manual lookups method for assigning Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT) concept identifiers using formally mapped concepts from the Omaha System interface terminology. Clinicians who were students in a doctoral nursing program conducted 21 lookups for Omaha System terms in publicly available SNOMED CT browsers. Lookups were deemed successful if results matched exactly with the corresponding code from the January 2013 SNOMED CT-Omaha System terminology cross-map. Of the 21 manual lookups attempted, 12 (57.1%) were successful. Errors were due to semantic gaps differences in granularity and synonymy or partial term matching. Achieving rigor in clinical knowledge representation across settings, vendors and health systems is a globally recognized challenge. Cross-maps have potential to improve rigor in SNOMED CT encoding of clinical data. Further research is needed to evaluate outcomes of using of terminology cross-maps to encode clinical terms with SNOMED CT concept identifiers based on interface terminologies.
Executable medical guidelines with Arden Syntax-Applications in dermatology and obstetrics.
Seitinger, Alexander; Rappelsberger, Andrea; Leitich, Harald; Binder, Michael; Adlassnig, Klaus-Peter
2016-08-12
Clinical decision support systems (CDSSs) are being developed to assist physicians in processing extensive data and new knowledge based on recent scientific advances. Structured medical knowledge in the form of clinical alerts or reminder rules, decision trees or tables, clinical protocols or practice guidelines, score algorithms, and others, constitute the core of CDSSs. Several medical knowledge representation and guideline languages have been developed for the formal computerized definition of such knowledge. One of these languages is Arden Syntax for Medical Logic Systems, an International Health Level Seven (HL7) standard whose development started in 1989. Its latest version is 2.10, which was presented in 2014. In the present report we discuss Arden Syntax as a modern medical knowledge representation and processing language, and show that this language is not only well suited to define clinical alerts, reminders, and recommendations, but can also be used to implement and process computerized medical practice guidelines. This section describes how contemporary software such as Java, server software, web-services, XML, is used to implement CDSSs based on Arden Syntax. Special emphasis is given to clinical decision support (CDS) that employs practice guidelines as its clinical knowledge base. Two guideline-based applications using Arden Syntax for medical knowledge representation and processing were developed. The first is a software platform for implementing practice guidelines from dermatology. This application employs fuzzy set theory and logic to represent linguistic and propositional uncertainty in medical data, knowledge, and conclusions. The second application implements a reminder system based on clinically published standard operating procedures in obstetrics to prevent deviations from state-of-the-art care. A to-do list with necessary actions specifically tailored to the gestational week/labor/delivery is generated. Today, with the latest versions of Arden Syntax and the application of contemporary software development methods, Arden Syntax has become a powerful and versatile medical knowledge representation and processing language, well suited to implement a large range of CDSSs, including clinical-practice-guideline-based CDSSs. Moreover, such CDS is provided and can be shared as a service by different medical institutions, redefining the sharing of medical knowledge. Arden Syntax is also highly flexible and provides developers the freedom to use up-to-date software design and programming patterns for external patient data access. Copyright © 2016.

Assessment of the iodine concentration in table salt at the production stage in South Africa.
Jooste, Pieter L.
2003-01-01
OBJECTIVE: To determine the iodine content of iodized salt at the production stage, to assess the perceptions and knowledge of salt producers about the prevention and control of iodine deficiency, and to examine the internal quality control procedures used during iodization in South Africa. METHOD: Salt samples were collected for iodine analysis by titration from the 12 producers iodizing salt in South Africa. Information on the producers' knowledge of iodine deficiency disorders and on internal quality control was obtained by means of questionnaires. FINDINGS: The legal requirement of 40-60 ppm iodine was met in 30.9% of salt samples; 57.9% contained more than 30 ppm iodine; 34.8% contained under 20 ppm iodine. There were shortcomings in perceptions and knowledge about iodine deficiency disorders and in the internal quality control procedures of a substantial proportion of the producers. CONCLUSION: In order to encourage and support salt producers to achieve optimal iodization there should be an information, education and communication strategy aimed at improving knowledge of iodine deficiency disorders and at raising the standard of internal quality control procedures. External monitoring should continue. PMID:12973644
The Idea of Patents vs. the Idea of University.
de Campos, Thana Cristina
2015-01-01
It is generally accepted that patents are a driving force for innovation through research and development. But the university's involvement in patenting is problematic as well. In particular, it is in tension with the idea of a university itself. If patents entail a restriction on the accessibility of the scientific knowledge that has been patented, and if the main purpose of universities is to produce and disseminate knowledge to the public, then, there is a tension: when universities patent their research innovations, they are making the scientific knowledge they produce less accessible to the public. The paper argues that university patenting contradicts the very idea of a university as an institution whose mission is fundamentally to disseminate the knowledge it produces to the public. The practice of university patenting involves an un-academic attitude thus: by inciting an attitude towards knowledge that is not consistent with the proper attitudes and goals of a university, university patenting hurts university's integrity.
Knowledge enabled plan of care and documentation prototype.
DaDamio, Rebecca; Gugerty, Brian; Kennedy, Rosemary
2006-01-01
There exist significant challenges in integrating the plan of care into documentation and point of care operational processes. A plan of care is often a static artifact that meets regulatory standards with limited influence on supporting goal-directed care delivery processes. Although this prototype is applicable to many clinical disciplines, we will highlight nursing processes in demonstrating a knowledge-driven computerized solution that fully integrates the plan of care within documentation. The knowledge-driven solution reflects evidenced-based practice; is an effective tool for managing problems, orders/interventions, and the patient's progress towards expected outcomes; meets regulatory standards; and drives quality and process improvement. The knowledge infrastructure consists of fully represented terminology, structured clinical expressions utilizing the controlled terminology and clinical knowledge representing evidence-based practice.

Background Australian General Practitioners (GPs) are in the forefront of primary health care and in an excellent position to communicate with their patients and educate them about Complementary Medicines (CMs) use. However previous studies have demonstrated that GPs lack the knowledge required about CMs to effectively communicate with patients about their CMs use and they perceive a need for information resources on CMs to use in their clinical practice. This study aimed to develop, implement, and evaluate a CMs information resource in Queensland (Qld) general practice. Methods The results of the needs assessment survey of Qld general practitioners (GPs) informed the development of a CMs information resource which was then put through an implementation and evaluation cycle in Qld general practice. The CMs information resource was a set of evidence-based herbal medicine fact sheets. This resource was utilised by 100 Qld GPs in their clinical practice for four weeks and was then evaluated. The evaluation assessed GPs' (1) utilisation of the resource (2) perceived quality, usefulness and satisfaction with the resource and (3) perceived impact of the resource on their knowledge, attitudes, and practice of CMs. Results Ninety two out of the 100 GPs completed the four week evaluation of the fact sheets and returned the post-intervention survey. The herbal medicine fact sheets produced by this study were well accepted and utilised by Qld GPs. The majority of GPs perceived that the fact sheets were a useful resource for their clinical practice. The fact sheets improved GPs' attitudes towards CMs, increased their knowledge of those herbal medicines and improved their communication with their patients about those specific herbs. Eighty-six percent of GPs agreed that if they had adequate resources on CMs, like the herbal medicine fact sheets, then they would communicate more to their patients about their use of CMs. Conclusion Further educational interventions on CMs need to be provided to GPs to increase their knowledge of CMs and to improve their communication with patients about their CMs use.

[Knowledge management system for laboratory work and clinical decision support].
Inada, Masanori; Sato, Mayumi; Yoneyama, Akiko
2011-05-01
This paper discusses a knowledge management system for clinical laboratories. In the clinical laboratory of Toranomon Hospital, we receive about 20 questions relevant to laboratory tests per day from medical doctors or co-medical staff. These questions mostly involve the essence to appropriately accomplish laboratory tests. We have to answer them carefully and suitably because an incorrect answer may cause a medical accident. Up to now, no method has been in place to achieve a rapid response and standardized answers. For this reason, the laboratory staff have responded to various questions based on their individual knowledge. We began to develop a knowledge management system to promote the knowledge of staff working for the laboratory. This system is a type of knowledge base for assisting the work, such as inquiry management, laboratory consultation, process management, and clinical support. It consists of several functions: guiding laboratory test information, managing inquiries from medical staff, reporting results of patient consultation, distributing laboratory staffs notes, and recording guidelines for laboratory medicine. The laboratory test information guide has 2,000 records of medical test information registered in the database with flexible retrieval. The inquiry management tool provides a methos to record all questions, answer easily, and retrieve cases. It helps staff to respond appropriately in a short period of time. The consulting report system treats patients' claims regarding medical tests. The laboratory staffs notes enter a file management system so they can be accessed to aid in clinical support. Knowledge sharing using this function can achieve the transition from individual to organizational learning. Storing guidelines for laboratory medicine will support EBM. Finally, it is expected that this system will support intellectual activity concerning laboratory work and contribute to the practice of knowledge management for clinical work support.
Evidence, research, knowledge: a call for conceptual clarity.
Scott-Findlay, Shannon; Pollock, Carolee
2004-01-01
To dispel some of the conceptual confusion in the field of evidence-based practice that has resulted from the overlapping use of the terms research, evidence, and knowledge. Theoretical discussion. Often the terms research and knowledge are used as synonyms for evidence, but the overlap is never complete. The term evidence has long been understood to mean the findings of research. Recent attempts to broaden the definition of evidence to include clinical experience and experiential knowledge have been misguided. Broadening our understanding of the basis for clinical decision making and conceptualizing evidence are quite different tasks. Other factors (not other forms of evidence) do shape the clinical decision-making process, but they are not evidence. We might better term them knowledge. Confusing evidence with these other factors has hindered research and the improvement of clinical decision making in health care. We argue that this confusion results from the use of the term evidence when we really mean either research findings or knowledge. In this article, we have argued for specificity in the use of the term evidence. We urge the restriction of the term evidence to research findings, and while we acknowledge the importance of other influences on the clinical decision-making process, we insist that they are not evidence. The time has come to value personal experience and experiential knowledge for what they are-we should not have to disguise them as types of evidence for them to be deemed of any value. Being specific to language, the goal is to improve clinical decision making by increasing practitioners' reliance on research findings (evidence) while acknowledging (and valuing) the important part played by other forms of knowledge in the decision-making process. The distinctions are important.
Knowledge acquisition for temporal abstraction.
Stein, A; Musen, M A; Shahar, Y
1996-01-01
Temporal abstraction is the task of detecting relevant patterns in data over time. The knowledge-based temporal-abstraction method uses knowledge about a clinical domain's contexts, external events, and parameters to create meaningful interval-based abstractions from raw time-stamped clinical data. In this paper, we describe the acquisition and maintenance of domain-specific temporal-abstraction knowledge. Using the PROTEGE-II framework, we have designed a graphical tool for acquiring temporal knowledge directly from expert physicians, maintaining the knowledge in a sharable form, and converting the knowledge into a suitable format for use by an appropriate problem-solving method. In initial tests, the tool offered significant gains in our ability to rapidly acquire temporal knowledge and to use that knowledge to perform automated temporal reasoning.
Health information literacy: hardwiring behavior through multilevels of instruction and application.
Leasure, A Renee; Delise, Donna; Clifton, Shari C; Pascucci, Mary Ann
2009-01-01
To produce a healthcare provider who is competent in accessing health information, nursing faculty members, in tandem with medical librarians, play a crucial role in establishing the knowledge base for student competency in health information literacy. The time to prepare nursing students to meet the information challenges and opportunities of today's healthcare environment is not after graduation, but rather while they are in school. By incorporating health information literacy skill building throughout the curriculum, nursing faculty members can prepare their students to enter the workforce equipped with the skills they need to find, retrieve, appraise, and apply information to their clinical practice.

Objective Cognitive impairment is a characteristic of schizophrenia. This impairment may affect the retention of information required for ongoing knowledgeable participation in clinical trials. This study monitored retention of study-related knowledge--including assessment of therapeutic misconception--in people with stable, DSM-IV schizophrenia during participation in placebo-controlled clinical trials of adjunctive agents. Stability was defined as being on an antipsychotic with no change in medication or dose over the previous 4 weeks. Method Individuals enrolling in one of seven clinical trials were approached for participation. Participants came from research clinics and community mental health centers. At baseline, clinical trial consent forms were reviewed and study knowledge assessed. Participants were randomized to follow-up assessments at weeks 1, 4, and 8; weeks 4 and 8; or at week 8 only. Clinical trial consent forms were not re-reviewed at any follow-up visit. Results Fifty-nine participants were enrolled; analysis included 52 participants with at least one follow-up visit. Study knowledge did not decrease meaningfully in any group. Therapeutic misconception was not observed in participants during the study. The group assessed most frequently demonstrated significant improvement over baseline (t44= 3.43, p= 0.001). Retention of study knowledge was not related to symptoms, but had a weak correlation with cognitive capacity (R= 0.28, p= 0.07). Performance did not differ between participants from research clinics and those from community mental health centers. Conclusions Clinically-stable people with schizophrenia enrolling in a placebo-controlled adjunctive medication study, once determined to have capacity to consent to a clinical trial, retained appropriate study knowledge for at least 8 weeks. In the absence of a specific reason to suspect a loss of decisional capacity, there appears to be no need to routinely re-evaluate participants during this type of clinical trial. PMID:23842013

The healthcare industry is dependent upon the provision of well designed medical devices. To achieve this it is recommended that user-centred design should begin early, and continue throughout device development. This is a challenge, particularly for smaller companies who may lack the necessary expertise and knowledge. The aim of this study was to conduct a rigorous yet focused investigation into the user requirements for a new medical imaging device. Open-ended semi-structured interviews were conducted with potential clinical users of the device to investigate the clinical need for the device and the potential benefits for patients and clinical users. The study identified a number of new and significant clinical needs that suggested that the concept of the device should be fundamentally changed. The clinical and organisational priorities of the clinical users were identified, as well as a number of factors that would act as barriers to the safe and effective adoption of the device. The developers reported that this focused approach to early requirements elicitation would result in an improved product, reduce the time to market, and save the time and cost of producing and evaluating an inappropriate prototype.

Core competencies in clinical neuropsychology training across the world.
Hessen, Erik; Hokkanen, Laura; Ponsford, Jennie; van Zandvoort, Martine; Watts, Ann; Evans, Jonathan; Haaland, Kathleen Y
2018-05-01
This work aimed to review main competency requirements from training models in countries with well-established specialties in clinical neuropsychology and to extract core competencies that likely will apply to clinical neuropsychologists regardless of regional and cultural context. We reviewed standards for post-graduate training in clinical neuropsychology from countries in Europe, Australia, and North America based on existing literature, presentations at international conferences, and from description of the training models from national psychological or neuropsychological associations. Despite differences, the reviewed models share similar core competencies considered necessary for a specialty in clinical neuropsychology: (1) In-depth knowledge of general psychology including clinical psychology (post-graduate level), ethical, and legal standards. (2) Expert knowledge about clinically relevant brain-behavioral relationships. (3) Comprehensive knowledge about, and skills in, related clinical disciplines. (4) In-depth knowledge about and skills in neuropsychological assessment, including decision-making and diagnostic competency according to current classification of diseases. (5) Competencies in the area of diversity and culture in relation to clinical neuropsychology. (6) Communication competency of neuropsychological findings and test results to relevant and diverse audiences. (7) Knowledge about and skills in psychological and neuropsychological intervention, including treatment and rehabilitation. All the models have undergone years of development in accordance with requirements of national health care systems in different parts of the world. Despite differences, the common core competency requirements across different regions of the world suggest generalizability of these competencies. We hope this summary can be useful as countries with less established neuropsychology training programs develop their models.
Knowledge Translation Tools are Emerging to Move Neck Pain Research into Practice.
Macdermid, Joy C; Miller, Jordan; Gross, Anita R
2013-01-01
Development or synthesis of the best clinical research is in itself insufficient to change practice. Knowledge translation (KT) is an emerging field focused on moving knowledge into practice, which is a non-linear, dynamic process that involves knowledge synthesis, transfer, adoption, implementation, and sustained use. Successful implementation requires using KT strategies based on theory, evidence, and best practice, including tools and processes that engage knowledge developers and knowledge users. Tools can provide instrumental help in implementing evidence. A variety of theoretical frameworks underlie KT and provide guidance on how tools should be developed or implemented. A taxonomy that outlines different purposes for engaging in KT and target audiences can also be useful in developing or implementing tools. Theoretical frameworks that underlie KT typically take different perspectives on KT with differential focus on the characteristics of the knowledge, knowledge users, context/environment, or the cognitive and social processes that are involved in change. Knowledge users include consumers, clinicians, and policymakers. A variety of KT tools have supporting evidence, including: clinical practice guidelines, patient decision aids, and evidence summaries or toolkits. Exemplars are provided of two KT tools to implement best practice in management of neck pain-a clinician implementation guide (toolkit) and a patient decision aid. KT frameworks, taxonomies, clinical expertise, and evidence must be integrated to develop clinical tools that implement best evidence in the management of neck pain.

Structured patient data like Electronic Health Records (EHRs) are a valuable source for clinical research. However, the sensitive nature of such information requires some anonymisation procedure to be applied before releasing the data to third parties. Several studies have shown that the removal of identifying attributes, like the Social Security Number, is not enough to obtain an anonymous data file, since unique combinations of other attributes as for example, rare diagnoses and personalised treatments, may lead to patient's identity disclosure. To tackle this problem, Statistical Disclosure Control (SDC) methods have been proposed to mask sensitive attributes while preserving, up to a certain degree, the utility of anonymised data. Most of these methods focus on continuous-scale numerical data. Considering that part of the clinical data found in EHRs is expressed with non-numerical attributes as for example, diagnoses, symptoms, procedures, etc., their application to EHRs produces far from optimal results. In this paper, we propose a general framework to enable the accurate application of SDC methods to non-numerical clinical data, with a focus on the preservation of semantics. To do so, we exploit structured medical knowledge bases like SNOMED CT to propose semantically-grounded operators to compare, aggregate and sort non-numerical terms. Our framework has been applied to several well-known SDC methods and evaluated using a real clinical dataset with non-numerical attributes. Results show that the exploitation of medical semantics produces anonymised datasets that better preserve the utility of EHRs. Copyright © 2012 Elsevier Inc. All rights reserved.
The gap between available knowledge and its use in clinical psychiatry.

The time span between knowledge becoming available and its integration into daily clinical routine is lengthy. This phenomenon is explored in this study. We used the outcomes of our activities for investigating and strengthening the research-based activities to improve physical health in the routines of clinical psychiatric wards as examples for our analyses. The time span between new knowledge becoming available and its implementation into general clinical treatment is very long. However, a shortening of this time span is seen through active leadership backup and clinical research experience among psychiatrists and staff in the wards. In particular, the involvement of medical students interested in clinical research activities seems to have a positive impact. Academia needs to be re-implemented into clinical psychiatry. Staff with research experience is needed in all professions to increase evidence-based practice. Leaders must take responsibility for implementing new knowledge into the routines of the department and must support staff in these activities on a daily basis. © 2015 John Wiley & Sons A/S.

There has been widespread acknowledgement of the need to build capacity in knowledge translation however much of the existing work focuses on building capacity amongst researchers rather than with clinicians directly. This paper's aim is to describe a research project for developing a knowledge translation capacity building program for occupational therapy clinicians. Participatory action research methods were used to both develop and evaluate the knowledge translation capacity-building program. Participants were occupational therapists from a large metropolitan hospital in Australia. Researchers and clinicians worked together to use the action cycle of the Knowledge to Action Framework to increase use of knowledge translation itself within the department in general, within their clinical teams, and to facilitate knowledge translation becoming part of the department's culture. Barriers and enablers to using knowledge translation were identified through a survey based on the Theoretical Domains Framework and through focus groups. Multiple interventions were used to develop a knowledge translation capacity-building program. Fifty-two occupational therapists participated initially, but only 20 across the first 18 months of the project. Barriers and enablers were identified across all domains of the Theoretical Domains Framework. Interventions selected to address these barriers or facilitate enablers were categorised into ten different categories: educational outreach; teams working on clinical knowledge translation case studies; identifying time blocks for knowledge translation; mentoring; leadership strategies; communication strategies; documentation and resources to support knowledge translation; funding a knowledge translation champion one day per week; setting goals for knowledge translation; and knowledge translation reporting strategies. Use of these strategies was, and continues to be monitored. Participants continue to be actively involved in learning and shaping the knowledge translation program across the department and within their specific clinical areas. To build capacity for knowledge translation, it is important to involve clinicians. The action cycle of the Knowledge to Action framework is a useful guide to introduce the knowledge translation process to clinicians. It may be used to engage the department as a whole, and facilitate the learning and application of knowledge translation within specific clinical areas. Research evaluating this knowledge translation program is being conducted.

This study examined the effectiveness of the clinical teaching associate (CTA) model to improve clinical learning outcomes in nursing students. Students were randomly allocated to either the CTA (n = 28) or traditional training group (n = 32), and their clinical knowledge, skills, and satisfaction with the learning experience were assessed and compared. The results showed that the CTA model was equally effective in improving clinical knowledge, skills, and satisfaction of nursing students.
Organists and organ music composers.
Foerch, Christian; Hennerici, Michael G
2015-01-01
Clinical case reports of patients with exceptional musical talent and education provide clues as to how the brain processes musical ability and aptitude. In this chapter, selected examples from famous and unknown organ players/composers are presented to demonstrate the complexity of modified musical performances as well as the capacities of the brain to preserve artistic abilities: both authors are active organists and academic neurologists with strong clinical experience, practice, and knowledge about the challenges to play such an outstanding instrument and share their interest to explore potentially instrument-related phenomena of brain modulation in specific transient or permanent impairments. We concentrate on the sites of lesions, suggested pathophysiology, separate positive (e.g., seizures, visual or auditory hallucinations, or synesthesia [an involuntary perception produced by stimulation of another sense]) and negative phenomena (e.g., amusia, aphasia, neglect, or sensory-motor deficits) and particularly address aspects of recent concepts of temporary and permanent network disorders. © 2015 Elsevier B.V.

Transmission, Human Population, and Pathogenicity: the Ebola Case in Point.
Delgado, Rafael; Simón, Fernando
2018-03-01
The 2013-2016 Ebola outbreak in West Africa has been the largest ever of a known disease in a new context that produced an unprecedented impact and is changing the international approach to responding to public health emergencies. The unprecedented scale of the outbreak, the use of advanced technology for detecting and characterizing the infectious agent, along with the opportunity to treat patients in modern facilities have greatly increased our knowledge of the disease and its transmission. Also, for the first time, an important international effort has been deployed to control the spread of the epidemic by providing care to patients and by adopting basic measures of public health control. Apart from supportive treatment and intensive therapy with fluids and electrolytes, no new compounds have been proved to be clinically effective to treat Ebola virus disease; however, a specific vaccine has shown significant protection in clinical trials in Guinea, opening an expectation for controlling future outbreaks.
[Fundamentals and Clinical Applications of Transcranial Magnetic Stimulation in Neuropsychiatry].
Malavera, Mayra; Silva, Federico; García, Ronald; Rueda, Ligia; Carrillo, Sandra
2014-03-01
Transcranial Magnetic Stimulation (TMS) is a non-invasive method for stimulation of brain that is based on the ability of a generated magnetic field to penetrate skull and brain meninges, inducing an electric current in the brain tissues that produces neuronal depolarization. TMS can be applied as single pulse of stimulation, pairs of stimuli separated by variable intervals to the same or different brain areas, or as trains of repetitive stimuli at various frequencies. Its mechanism of action is currently unknown. Repetitive TMS can modify the excitability of the cerebral cortex, and has been postulated as a diagnostic and therapeutic tool in the area of neuropsychiatry. The aim of this article is to review the knowledge of the TMS as regards its basic principles, pathophysiological mechanism, and its usefulness in clinical practice.

The purpose of this article is to highlight a number of underlying issues that may be useful for a comprehensive review of the management of Health-Related Science, Technology and Innovation policies (ST&I/H), and its strategies and priorities. It is an analytical study supported by an extensive review of the technical and journalistic literature, clippings, legislation and federal government directives. The results show that the Healthcare Production Complex undeniably and increasingly needs science to maintain itself. One may infer that a framework of institutional milestones is being built in Brazil, to strengthen, guide and encourage Research and Development, and that clinical research creates scientific knowledge to address public healthcare issues by generating new inputs or enhancing existing techniques, processes and technologies that will be produced, marketed and used in the different segments, thus feeding the Healthcare Productive Complex.
GEM at 10: a decade's experience with the Guideline Elements Model.
Hajizadeh, Negin; Kashyap, Nitu; Michel, George; Shiffman, Richard N
2011-01-01
The Guideline Elements Model (GEM) was developed in 2000 to organize the information contained in clinical practice guidelines using XML and to represent guideline content in a form that can be understood by human readers and processed by computers. In this work, we systematically reviewed the literature to better understand how GEM was being used, potential barriers to its use, and suggestions for improvement. Fifty external and twelve internally produced publications were identified and analyzed. GEM was used most commonly for modeling and ontology creation. Other investigators applied GEM for knowledge extraction and data mining, for clinical decision support for guideline generation. The GEM Cutter software-used to markup guidelines for translation into XML- has been downloaded 563 times since 2000. Although many investigators found GEM to be valuable, others critiqued its failure to clarify guideline semantics, difficulties in markup, and the fact that GEM files are not usually executable.

The uptake and use of clinical guidelines is often insufficient to change clinical behaviour and reduce variation in practice. As a consequence of diverse organisational contexts, the simple provision of guidelines cannot ensure fidelity or guarantee their use when making decisions. Implementation research in surgery has focused on understanding what evidence exists for clinical practice decisions but limits understanding to the technical, educational and accessibility issues. This research aims to identify where, when and how evidence and knowledge are used in orthopaedic decision-making and how variation in these factors contributes to different approaches to implementation of clinical guidance in practice. We used in-depth case studies to examine guideline implementation in real-life surgical practice. We conducted comparative case studies in three English National Health Service hospitals over a 12-month period. Each in-depth case study consisted of a mix of qualitative methods including interviews, observations and document analysis. Data included field notes from observations of day-to-day practice, 64 interviews with NHS surgeons and staff and the collection of 121 supplementary documents. Case studies identified 17 sources of knowledge and evidence which influenced clinical decisions in elective orthopaedic surgery. A comparative analysis across cases revealed that each hospital had distinct approaches to decision-making. Decision-making is described as occurring as a result of how 17 types of knowledge and evidence were privileged and of how they interacted and changed in context. Guideline implementation was contingent and mediated through four distinct contextual levels. Implementation could be assessed for individual surgeons, groups of surgeons or the organisation as a whole, but it could also differ between these levels. Differences in how evidence and knowledge were used contributed to variations in practice from guidelines. A range of complex and competing sources of evidence and knowledge exists which influence the working practices of healthcare professionals. The dynamic selection, combination and use of each type of knowledge and evidence influence the implementation and use of clinical guidance in practice. Clinical guidelines are a fundamental part of practice, but represent only one type of evidence influencing clinical decisions. In the orthopaedic speciality, other distinct sources of evidence and knowledge are selected and used which impact on how guidelines are implemented. New approaches to guideline implementation need to appreciate and incorporate this diverse range of knowledge and evidence which influences clinical decisions and to take account of the changing contexts in which decisions are made.

In this article based on a literary study, the form of knowledge named familiarity knowledge is examined. Although rooted in the philosophical tradition of Wittgenstein and Polanyi, the development of familiarity knowledge is tied in with clinical practice and particular patients and contexts while paying attention to the framework factors influencing the setting as a whole as well as with theoretical knowledge relevant to the situation at hand. Palliative care makes a backdrop for some of the discussion. Familiarity knowledge can never be context free and attends to that which is unique in every nurse-patient relationship. Both assertive and familiarity knowledge are needed to care for dying patients in a competent, sensitive, and truly caring manner. Mentors need to help students synthesize assertive knowledge and familiarity knowledge during their clinical studies to enrich both kinds of knowledge and deepen their understanding. Student nurses expertly mentored and tutored while caring for dying patients living at home become, for instance, less apprehensive about facing dying patients than students not so mentored. Nurses need to understand the complexity of nursing care to be able to see the uniqueness of the situation and approach the individual patient on the bases of experience and insight.
MO-DE-BRA-05: Developing Effective Medical Physics Knowledge Structures: Models and Methods
DOE Office of Scientific and Technical Information (OSTI.GOV)
Sprawls, P
Purpose: Develop a method and supporting online resources to be used by medical physics educators for teaching medical imaging professionals and trainees so they develop highly-effective physics knowledge structures that can contribute to improved diagnostic image quality on a global basis. Methods: The different types of mental knowledge structures were analyzed and modeled with respect to both the learning and teaching process for their development and the functions or tasks that can be performed with the knowledge. While symbolic verbal and mathematical knowledge structures are very important in medical physics for many purposes, the tasks of applying physics in clinicalmore » imaging--especially to optimize image quality and diagnostic accuracy--requires a sensory conceptual knowledge structure, specifically, an interconnected network of visually based concepts. This type of knowledge supports tasks such as analysis, evaluation, problem solving, interacting, and creating solutions. Traditional educational methods including lectures, online modules, and many texts are serial procedures and limited with respect to developing interconnected conceptual networks. A method consisting of the synergistic combination of on-site medical physics teachers and the online resource, CONET (Concept network developer), has been developed and made available for the topic Radiographic Image Quality. This was selected as the inaugural topic, others to follow, because it can be used by medical physicists teaching the large population of medical imaging professionals, such as radiology residents, who can apply the knowledge. Results: Tutorials for medical physics educators on developing effective knowledge structures are being presented and published and CONET is available with open access for all to use. Conclusion: An adjunct to traditional medical physics educational methods with the added focus on sensory concept development provides opportunities for medical physics teachers to share their knowledge and experience at a higher cognitive level and produce medical professionals with the enhanced ability to apply physics to clinical procedures.« less
Beyond Trust: Plagiarism and Truth.
Penders, Bart
2018-03-01
Academic misconduct distorts the relationship between scientific practice and the knowledge it produces. The relationship between science and the knowledge it produces is, however, not something universally agreed upon. In this paper I will critically discuss the moral status of an act of research misconduct, namely plagiarism, in the context of different epistemological positions. While from a positivist view of science, plagiarism only influences trust in science but not the content of the scientific corpus, from a constructivist point of view both are at stake. Consequently, I argue that discussions of research misconduct and responsible research ought to be explicitly informed by the authors' views on the relationship between science and the knowledge it produces.
People Use their Knowledge of Common Events to Understand Language, and Do So as Quickly as Possible
McRae, Ken; Matsuki, Kazunaga
2011-01-01
People possess a great deal of knowledge about how the world works, and it is undoubtedly true that adults use this knowledge when understanding and producing language. However, psycholinguistic theories differ regarding whether this extra-linguistic pragmatic knowledge can be activated and used immediately, or only after a delay. The authors present research that investigates whether people immediately use their generalized knowledge of common events when understanding language. This research demonstrates that (i) individual isolated words immediately activate event-based knowledge; (ii) combinations of words in sentences immediately constrain people’s event-based expectations for concepts that are upcoming in language; (iii) syntax modulates people’s expectations for ensuing concepts; and (iv) event-based knowledge can produce expectations for ensuing syntactic structures. It is concluded that theories of sentence comprehension must allow for the rapid dynamic interplay among these sources of information. PMID:22125574

Academic activity during internship is essentially practical and ward rounds are traditionally considered the cornerstone of clinical education. However, the efficacy and effectiveness of ward rounds for learning purposes have been under-investigated and it is necessary to assess alternative educational paradigms for this activity. This study aimed to compare the educational effectiveness of ward rounds conducted with two different learning methodologies. Student subjects were first tested on 30 true/false questions to assess their initial degree of knowledge on pneumonia and diarrhoea. Afterwards, they attended ward rounds conducted using an active and a traditional learning methodology. The participants were submitted to a second test 48hours later in order to assess knowledge acquisition and were asked to answer two questions about self-directed learning and their opinions on the two learning methodologies used. Seventy-two medical students taking part in a paediatric clinic rotation were enrolled. The active methodology proved to be more effective than the traditional methodology for the three outcomes considered: knowledge acquisition (33 students [45.8%] versus 21 students [29.2%]; p=0.03); self-directed learning (38 students [52.8%] versus 11 students [15.3%]; p<0.001), and student opinion on the methods (61 students [84.7%] versus 38 students [52.8%]; p<0.001). The active methodology produced better results than the traditional methodology in a ward-based context. This study seems to be valuable in terms of the new evidence it demonstrates on learning methodologies in the context of the ward round. © Blackwell Publishing Ltd 2011.

Over the last 15 years there has been an increasingly energetic search for theories and definitions in the burgeoning area of knowledge translation (KT) in the health care context. The focus has been on the design and evaluation of KT activities with little attention to developing a considered KT theoretical/methodological approach that takes a more distanced critical inquiry to the studying of KT interventions. As such, what has been overlooked in the health professions KT literature to date is a suitably complex conceptualisation of translation that encompasses the multiplicity of KT interventions, the dynamic environments in which they are occurring, and the production of new knowledge which arises from their interactions. Attending to these epistemological issues; i.e. issues of the type of knowledge and how it is produced, is crucial to developing a relational understanding of the production and emergence of context-specific clinical knowledge and practice in KT processes. Such an approach is compared to the traditional KT evaluations by KT practitioners themselves of the compliance or non-compliance of individual and organisational behaviour change. A Sociology of KT (SKT) is proposed to complement the applied and evaluative research practice of implementing planned action KT activities. The purpose of a SKT basic research agenda is to understand both the context-specific nature of KT interventions and the epistemological premises of the activities of KT implementers themselves, in order to advance the science of KT and inform, complement and add to the success of applied and evaluative KT research in the future.

To debate about the application of on-going 'revolutions' in medical knowledge to Spanish neurological journals in the 21st century. This article reviews the current status of five revolutions in the field of health sciences, in general, and in neurological sciences, in particular: 1) the knowledge revolution: to translate the scientific investigation to the patient, with knowledge needs-driven research agenda with founder commissioning research to answer questions posed by clinicians, managers and patients, and systematic and critical appraisal reviews as the creator of quality improved knowledge; 2) the evidence based medicine revolution: the pyramid information of '4S', with systems (guidelines and computerized decision support systems), synopses (secondary journals), syntheses (systematic reviews and meta-analysis) and studies (original studies published in journals); 3) the web revolution: the possibility of dissemination of biomedical documentation by means of the Internet network are producing changes in the traditional way of conceiving scientific publication; the Internet represents a great advantage for investigation and also for clinical practice, since it permits free, universal access to databases and the interchange of texts, images and videos; 4) the open access revolution: to take full control over all operations related to the process of publish (to create, publish, communicate, distribute, reproduce and transform) with no need of any intermediaries, and to transform fundamental aspects concerning the circulation of knowledge, its use and availability; and 5) the librarian revolution: the project of a Virtual Health Library in Spain as a tool to access and disseminate scientific and technical knowledge on health through the Internet.

Institutional Review Board (IRB) members have a duty to protect the integrity of the research process, but little is known about their basic knowledge of clinical research study designs. A nationwide sample of IRB members from major US research universities completed a web-based questionnaire consisting of 11 questions focusing on basic knowledge about clinical research study designs. It included questions about randomized controlled trials (RCTs) and other observational research study designs. Potential predictors (age, gender, educational attainment, type of IRB, current IRB membership, years of IRB service, clinical research experience, and self-identification as a scientist) of incorrect answers were evaluated using multivariate logistic regression models. 148 individuals from 36 universities participated. The majority of participants, 68.9% (102/148), were holding a medical or doctoral degree. Overall, only 26.5% (39/148) of participants achieved a perfect score of 11. On the six-question subset addressing RCTs, 46.6% (69/148) had a perfect score. Most individual questions, and the summary model of overall quiz score (perfect vs. not perfect), revealed no significant predictors - indicating that knowledge deficits were not limited to specific subgroups of IRB members. For the RCT knowledge score there was one significant predictor: compared with MDs, IRB members without a doctoral degree were three times as likely to answer at least one RCT question incorrectly (Odds Ratio: 3.00, 95% CI 1.10-8.20). However, even among MD IRB members, 34.1% (14/41) did not achieve a perfect score on the six RCT questions. This first nationwide study of IRB member knowledge about clinical research study designs found significant knowledge deficits. Knowledge deficits were not limited to laypersons or community advocate members of IRBs, as previously suggested. Akin to widespread ethical training requirements for clinical researchers, IRB members should undergo systematic training on clinical research designs.
Mediated learning in the workplace: student perspectives on knowledge resources.
Shanahan, Madeleine
2015-01-01
In contemporary clinical practice, student radiographers can use many types of knowledge resources to support their learning. These include workplace experts, digital and nondigital information sources (eg, journals, textbooks, and the Internet), and electronic communication tools such as e-mail and social media. Despite the range of knowledge tools available, there is little available data about radiography students' use of these resources during clinical placement. A 68-item questionnaire was distributed to 62 students enrolled in an Australian university undergraduate radiography program after they completed a clinical placement. Researchers used descriptive statistics to analyze student access to workplace experts and their use of digital and nondigital information sources and electronic communication tools. A 5-point Likert scale (1 = very important; 5 = not important) was used to assess the present importance and perceived future value of knowledge tools for workplace learning. Of the 53 students who completed and returned the questionnaire anonymously, most rely on the knowledge of practicing technologists and on print and electronic information sources to support their learning; some students also use electronic communication tools. Students perceive that these knowledge resources also will be important tools for their future learning as qualified health professionals. The findings from this study present baseline data regarding the value students attribute to multiple knowledge tools and regarding student access to and use of these tools during clinical placement. In addition, most students have access to multiple knowledge tools in the workplace and incorporate these tools simultaneously into their overall learning practice during clinical placement. Although a range of knowledge tools is used in the workplace to support learning among student radiographers, the quality of each tool should be critically analyzed before it is adopted in practice. Integrating practice-based learning with learning mediated by information sources provides a more complete paradigm of learning during clinical placement.
Knowledge-driven genomic interactions: an application in ovarian cancer.

Effective cancer clinical outcome prediction for understanding of the mechanism of various types of cancer has been pursued using molecular-based data such as gene expression profiles, an approach that has promise for providing better diagnostics and supporting further therapies. However, clinical outcome prediction based on gene expression profiles varies between independent data sets. Further, single-gene expression outcome prediction is limited for cancer evaluation since genes do not act in isolation, but rather interact with other genes in complex signaling or regulatory networks. In addition, since pathways are more likely to co-operate together, it would be desirable to incorporate expert knowledge to combine pathways in a useful and informative manner. Thus, we propose a novel approach for identifying knowledge-driven genomic interactions and applying it to discover models associated with cancer clinical phenotypes using grammatical evolution neural networks (GENN). In order to demonstrate the utility of the proposed approach, an ovarian cancer data from the Cancer Genome Atlas (TCGA) was used for predicting clinical stage as a pilot project. We identified knowledge-driven genomic interactions associated with cancer stage from single knowledge bases such as sources of pathway-pathway interaction, but also knowledge-driven genomic interactions across different sets of knowledge bases such as pathway-protein family interactions by integrating different types of information. Notably, an integration model from different sources of biological knowledge achieved 78.82% balanced accuracy and outperformed the top models with gene expression or single knowledge-based data types alone. Furthermore, the results from the models are more interpretable because they are framed in the context of specific biological pathways or other expert knowledge. The success of the pilot study we have presented herein will allow us to pursue further identification of models predictive of clinical cancer survival and recurrence. Understanding the underlying tumorigenesis and progression in ovarian cancer through the global view of interactions within/between different biological knowledge sources has the potential for providing more effective screening strategies and therapeutic targets for many types of cancer.

Previously we generated a chronic obstructive pulmonary disease (COPD) specific knowledge base (http://www.copdknowledgebase.eu) from clinical and experimental data, text-mining results and public databases. This knowledge base allowed the retrieval of specific molecular networks together with integrated clinical and experimental data. The COPDKB has now been extended to integrate over 40 public data sources on functional interaction (e.g. signal transduction, transcriptional regulation, protein-protein interaction, gene-disease association). In addition we integrated COPD-specific expression and co-morbidity networks connecting over 6 000 genes/proteins with physiological parameters and disease states. Three mathematical models describing different aspects of systemic effects of COPD were connected to clinical and experimental data. We have completely redesigned the technical architecture of the user interface and now provide html and web browser-based access and form-based searches. A network search enables the use of interconnecting information and the generation of disease-specific sub-networks from general knowledge. Integration with the Synergy-COPD Simulation Environment enables multi-scale integrated simulation of individual computational models while integration with a Clinical Decision Support System allows delivery into clinical practice. The COPD Knowledge Base is the only publicly available knowledge resource dedicated to COPD and combining genetic information with molecular, physiological and clinical data as well as mathematical modelling. Its integrated analysis functions provide overviews about clinical trends and connections while its semantically mapped content enables complex analysis approaches. We plan to further extend the COPDKB by offering it as a repository to publish and semantically integrate data from relevant clinical trials. The COPDKB is freely available after registration at http://www.copdknowledgebase.eu.

Objective: Clinical trials investigating drugs that target specific genetic alterations in tumors are important for promoting personalized cancer therapy. The goal of this project is to create a knowledge base of cancer treatment trials with annotations about genetic alterations from ClinicalTrials.gov. Methods: We developed a semi-automatic framework that combines advanced text-processing techniques with manual review to curate genetic alteration information in cancer trials. The framework consists of a document classification system to identify cancer treatment trials from ClinicalTrials.gov and an information extraction system to extract gene and alteration pairs from the Title and Eligibility Criteria sections of clinical trials. By applying the framework to trials at ClinicalTrials.gov, we created a knowledge base of cancer treatment trials with genetic alteration annotations. We then evaluated each component of the framework against manually reviewed sets of clinical trials and generated descriptive statistics of the knowledge base. Results and Discussion: The automated cancer treatment trial identification system achieved a high precision of 0.9944. Together with the manual review process, it identified 20 193 cancer treatment trials from ClinicalTrials.gov. The automated gene-alteration extraction system achieved a precision of 0.8300 and a recall of 0.6803. After validation by manual review, we generated a knowledge base of 2024 cancer trials that are labeled with specific genetic alteration information. Analysis of the knowledge base revealed the trend of increased use of targeted therapy for cancer, as well as top frequent gene-alteration pairs of interest. We expect this knowledge base to be a valuable resource for physicians and patients who are seeking information about personalized cancer therapy. PMID:27013523

Advancements in informatics in radiotherapy are opening up opportunities to improve our ability to assess treatment plans. Models on individualizing patient dose constraints from prior patient data and shape relationships have been extensively researched and are now making their way into commercial products. New developments in knowledge based treatment planning involve understanding the impact of the radiation dosimetry on the patient. Akin to radiobiology models that have driven intensity modulated radiotherapy optimization, toxicity and outcome predictions based on treatment plans and prior patient experiences may be the next step in knowledge based planning. In order to realize these predictions, itmore » is necessary to understand how the clinical information can be captured, structured and organized with ontologies and databases designed for recall. Large databases containing radiation dosimetry and outcomes present the opportunity to evaluate treatment plans against predictions of toxicity and disease response. Such evaluations can be based on dose volume histogram or even the full 3-dimensional dose distribution and its relation to the critical anatomy. This session will provide an understanding of ontologies and standard terminologies used to capture clinical knowledge into structured databases; How data can be organized and accessed to utilize the knowledge in planning; and examples of research and clinical efforts to incorporate that clinical knowledge into planning for improved care for our patients. Learning Objectives: Understand the role of standard terminologies, ontologies and data organization in oncology Understand methods to capture clinical toxicity and outcomes in a clinical setting Understand opportunities to learn from clinical data and its application to treatment planning Todd McNutt receives funding from Philips, Elekta and Toshiba for some of the work presented.« less

The application of evidence-based and standardized knowledge is an important basis for coordinated and effective clinical work. A multicenter study, which was conducted in 30 clinical neurology departments and included 99 junior and senior registrars, addressed aspects of practical knowledge of stroke treatment by open structured oral interviews which were analyzed with respect to interphysician and guideline conformity. In addition, the participants were asked to rate the usefulness of various informational sources and describe their informational sources used according to the aspects of practical knowledge addressed. The respective departmental directors were questioned about the sources of medical knowledge accessible in their clinic. In almost all hospitals, physicians had access to a library and the Internet. However, departments differed with respect to their information management (frequency and type of medical education, quality management, participation in research activities). In accordance with other studies, the knowledge sources reported most often were textbooks, journals and clinical studies. For most sources, the usefulness rankings largely corresponded to the rankings of user behavior. Both were only weak predictors for interphysician and guideline conformity. They are more closely related to the within-department homogeneity of practical knowledge than to interdepartmental and guideline conformity. Within-department homogeneity is enhanced by the use of recent, published and evidence-based sources and topical interaction with clinical colleagues. Guideline conformity was related to the use of databases and professional journals. A preference for colleagues from out-patient practices diminished both interphysician and guideline conformity. It seems there is still untapped potential for within-department knowledge management, such as medical education, implementation and use of guidelines and topical discussions, which may enhance the homogeneity and guideline conformity of the practical knowledge that clinicians apply.

Unsustainable health care costs coupled with opportunity for improvement in health care outcomes in the United States are stimulating meaningful transformation in the way we deliver care. One approach in this transformation focuses on minimizing unnecessary variation in physician practices, instead focusing on evidence-based medicine in a more uniform manner. Clinical practice guidelines contain evidence-based recommendations, articulate goals of care, and can help to reduce unnecessary variation. While thousands of clinical practice guidelines are in existence, a clinical gap exists between knowledge and clinical performance. With thoughtful guidelines implementation strategies in place, organizations can begin to close the gap and translate best practice knowledge into care. Health systems that have done this effectively have seen improved clinical outcomes, improved patient satisfaction, and lower cost per patient.

Commissioning a new treatment planning system (TPS) involves many time-consuming tasks. We investigated the role that knowledge-based planning (KBP) can play in aiding a clinic's transition to a new TPS. Sixty clinically treated prostate/prostate bed intensity-modulated radiation therapy (IMRT) plans were exported from an in-house TPS and were used to create a KBP model in a newly implemented commercial application. To determine the benefit that KBP may have in a TPS transition, the model was tested on 2 groups of patients. Group 1 consisted of the first 10 prostate/prostate bed patients treated in the commercial TPS after the transition from the in-house TPS. Group 2 consisted of 10 patients planned in the commercial TPS after 8 months of clinical use. The KBP-generated plan was compared with the clinically used plan in terms of plan quality (ability to meet planning objectives and overall dose metrics) and planning efficiency (time required to generate clinically acceptable plans). The KBP-generated plans provided a significantly improved target coverage (p = 0.01) compared with the clinically used plans for Group 1, but yielded plans of comparable target coverage to the clinically used plans for Group 2. For the organs at risk, the KBP-generated plans produced lower doses, on average, for every normal-tissue objective except for the maximum dose to 0.1 cc of rectum. The time needed for the KBP-generated plans ranged from 6 to 15 minutes compared to 30 to 150 and 15 to 60 minutes for manual planning in Groups 1 and 2, respectively. KBP is a promising tool to aid in the transition to a new TPS. Our study indicates that high-quality treatment plans could have been generated in the newly implemented TPS more efficiently compared with not using KBP. Even after 8 months of the clinical use, KBP still showed an increase in plan quality and planning efficiency compared with manual planning.

Overviews of reviews are an evolving form of evidence synthesis. The Cochrane Child Health Field has been producing overviews since 2006, during which time the methods that have been used have changed, both due to the development of guidance within The Cochrane Collaboration and to the decisions made by individual author teams. This paper studies the first 29 overviews published in EBCH. To describe some aspects of the approaches taken in EBCH overviews to producing evidence syntheses relevant to the healthcare needs of children; to highlight the contribution that overviews can make to the knowledge base for treatment for a particular population. Data was extracted on: whether the overview included systematic review (SR) data only, or also data from individual trials not present in the included SRs; name(s) of the Cochrane Review Group (CRG) that prepared the included SRs; topics of the overviews as compared to the topics of the included reviews; age-subgroup analyses presented in the overviews. In 23 overviews, all published in 2012, the authors included trial data as well as SR data; two overviews addressed conditions not explicitly addressed by the included reviews; three overviews included pre-specified age-subgroup analyses. The aim of clinical relevance has been achieved by means such as: drawing from reviews produced by multiple CRGs; using SR evidence to explore clinically relevant topics that may not match exactly with the topics covered by the SRs; ensuring that the evidence in overviews is as up to date as possible by redoing searches and including trials not incorporated in the included SRs; and, where permitted by the data, using age-subgroup analyses to present the data in a way which matches the stages of childhood development. Overview authors are dependent on the nature of the data and methods reported in the included SRs. This suggests a need for further study about how SRs could be conducted in order to facilitate the conduct of overviews. Copyright © 2013 The Cochrane Collaboration.

There has been a growing emphasis on evidence-informed decision-making in health care. Systematic reviews, such as those produced by the Cochrane Collaboration, have been a key component of this movement. The UK National Institute for Health Research (NIHR) Systematic Review Programme currently supports 20 Cochrane Review Groups (CRGs). The aim of this study was to identify the impacts of Cochrane reviews published by NIHR-funded CRGs during the years 2007-2011. We sent questionnaires to CRGs and review authors, interviewed guideline developers and used bibliometrics and documentary review to get an overview of CRG impact and to evaluate the impact of a sample of 60 Cochrane reviews. We used a framework with four categories (knowledge production, research targeting, informing policy development and impact on practice/services). A total of 1,502 new and updated reviews were produced by the 20 NIHR-funded CRGs between 2007 and 2011. The clearest impacts were on policy with a total of 483 systematic reviews cited in 247 sets of guidance: 62 were international, 175 national (87 from the UK) and 10 local. Review authors and CRGs provided some examples of impact on practice or services, for example, safer use of medication, the identification of new effective drugs or treatments and potential economic benefits through the reduction in the use of unproven or unnecessary procedures. However, such impacts are difficult to objectively document, and the majority of reviewers were unsure if their review had produced specific impacts. Qualitative data suggested that Cochrane reviews often play an instrumental role in informing guidance, although a poor fit with guideline scope or methods, reviews being out of date and a lack of communication between CRGs and guideline developers were barriers to their use. Health and economic impacts of research are generally difficult to measure. We found that to be the case with this evaluation. Impacts on knowledge production and clinical guidance were easier to identify and substantiate than those on clinical practice. Questions remain about how we define and measure impact, and more work is needed to develop suitable methods for impact analysis.

Background Recognizing the importance of increased patient participation in healthcare decisions leads decision makers to consider effective ways to incorporate patient perspectives in Health Technology Assessment (HTA) processes. The implementation of local health HTA units in university hospitals in Quebec provides a unique opportunity to foster an increased participation of patients in decisions regarding health technologies and clinical interventions. This project explores strategies that could be effective in involving patients in HTA activities at the local level. To do so, three objectives are pursued: 1) To synthesise international knowledge and experiences on patient and public involvement in HTA activities; 2) To explore the perceptions of stakeholders (administrators, clinical managers, healthcare professionals, HTA producers, and patients) regarding strategies for involving patients in various HTA activities; and 3) To produce a consensual strategic framework that could guide interventions for involving patients in HTA activities at the local level. Methods A systematic review of the literature will be conducted to synthesise international knowledge and experiments regarding the implication of patients and public in HTA. Then, focus groups will be carried out with representatives of various stakeholder groups in order to explore their perceptions regarding patient participation in HTA. Based on findings from the systematic review and the focus groups, a framework to support patient participation in HTA activities will be proposed. It will then be validated during a deliberative meeting with the research team, composed of scientists and decision makers, and representatives from different groups involved in HTA in Quebec. This deliberative meeting will aim at identifying the type and the degree of participation as well as the adequate timing for involving patients in local HTA activities. Discussion Given the actual state of evidence, integrating patient perspective in HTA activities has the potential to improve the quality of healthcare services. This study provides an opportunity to bridge the gap between HTA producers and its ultimate end-user: the patient. It will provide guidance to support local HTA units in Quebec and elsewhere in their decisions regarding patient participation. The framework developed could be applied to design and implement strategies for involving patients in HTA activities. PMID:19327160

A substantial body of literature demonstrates that communication skills in medicine can be taught and retained through teaching and practice. Considerable evidence also reveals that characteristics such as gender, age, language and attitudes affect communication skills performance. Our study examined the characteristics, attitudes and prior communication skills training of residents to determine the relationship of each to patient-doctor communication. The relationship between communication skills proficiency and clinical knowledge application (biomedical and ethical) was also examined through the use of doctor-developed clinical content checklists, as very little research has been conducted in this area. A total of 78 first- and second-year residents across all departments at Dalhousie Medical School participated in a videotaped 4-station objective structured clinical examination presenting a range of communication and clinical knowledge challenges. A variety of instruments were used to gather information and assess performance. Two expert raters evaluated the videotapes. Significant relationships were observed between resident characteristics, prior communication skills training, clinical knowledge and communication skills performance. Females, younger residents and residents with English as first language scored significantly higher, as did residents with prior communication skills training. A significant positive relationship was found between the clinical content checklist and communication performance. Gender was the only characteristic related significantly to attitudes. Gender, age, language and prior communication skills training are related to communication skills performance and have implications for resident education. The positive relationship between communication skills proficiency and clinical knowledge application is important and should be explored further.

Nursing education contains both theoretical and practical training processes. Clinical training is the basis of nursing education. The quality of clinical training is closely related to the quality of the clinical learning environment. This study aimed to determine the transfer of theoretical knowledge into clinical practice by nursing students and the difficulties they experience during this process. A qualitative research design was used in the study. The study was conducted in 2015 with 30 nursing students in a university located in the east of Turkey, constituting three focus groups. The questions directed to the students during the focus group interviews were as follows: What do you think about your clinical training? How do you evaluate yourself in the process of putting your theoretical knowledge into clinical practice? What kind of difficulties are you experiencing in clinical practices? The data were interpreted using the method of content analysis. Most of the students reported that theoretical information they received was excessive, their ability to put most of this information into practice was weak, and they lacked courage to touch patients for fear of implementing procedures incorrectly. As a result of the analysis of the data, five main themes were determined: clinical training, guidance and communication, hospital environment and expectations. The results of this study showed that nursing students found their clinical knowledge and skills insufficient and usually failed to transfer their theoretical knowledge into clinical practices. The study observed that nursing students experienced various issues in clinical practices. In order to fix these issues and achieve an effective clinical training environment, collaboration should be achieved among nursing instructors, nurses, nursing school and hospital managements. Additionally, the number of nursing educators should be increased and training programs should be provided regarding effective clinical training methods. Copyright © 2018 Elsevier Ltd.

The purpose of medical education is to produce competent and capable professional practitioners who can combine the art and science of medicine. Moreover, this process must prepare individuals to practise in a field in which knowledge is increasing and the contexts in which that knowledge is applied are changing in unpredictable ways. The 'basic sciences' are important in the training of a physician. The goal of basic science training is to learn it in a way that the material can be applied in practice. Much effort has been expended to integrate basic science and clinical training, while adding many other topics to the medical curriculum. This effort has been challenging. The aims of the paper are (1) to propose a unifying conceptual framework that facilitates knowledge integration among all levels of living systems from cell to society and (2) illustrate the organizing principles with two examples of the framework in action - cybernetic systems (with feedback) and distributed robustness. Literature related to hierarchical and holarchical frameworks was reviewed. An organizing framework derived from living systems theory and spanning the range from molecular biology to health systems management was developed. The application of cybernetic systems to three levels (regulation of pancreatic beta cell production of insulin, physician adjustment of medication for glycaemic control and development and action of performance measures for diabetes care) was illustrated. Similarly distributed robustness was illustrated by the DNA damage response system and principles underlying patient safety. Each of the illustrated organizing principles offers a means to facilitate the weaving of basic science and clinical medicine throughout the course of study. The use of such an approach may promote systems thinking, which is a core competency for effective and capable medical practice. Published 2016.

To evaluate the feasibility of implementing an interdisciplinary, multifaceted knowledge translation intervention within long-term care (LTC) and to identify any challenges that should be considered in designing future studies. Cluster randomized controlled trial. Forty LTC homes across the province of Ontario, Canada. LTC teams composed of physicians, nurses, pharmacists, and other staff. Cluster-level feasibility measures, including recruitment, retention, data completion, and participation in the intervention. A process evaluation was completed by directors of care indicating which process/policy changes had been implemented. Recruitment and retention rates were 22% and 63%, respectively. Good fidelity with the intervention was achieved, including attendance at educational meetings. After ViDOS, 7 process indicators were being newly implemented by more than 50% of active intervention homes. Despite recruitment and retention challenges, the multifaceted intervention produced a number of policy/process changes and had good intervention fidelity.

Caffeine is the most commonly used drug in the world. Although consumption of low to moderate doses of caffeine is generally safe, an increasing number of clinical studies are showing that some caffeine users become dependent on the drug and are unable to reduce consumption despite knowledge of recurrent health problems associated with continued use. Thus, the World Health Organization and some health care professionals recognize caffeine dependence as a clinical disorder. In this comprehensive literature review, we summarize published research on the biological evidence for caffeine dependence; we provide a systematic review of the prevalence of caffeine dependence and rates of endorsement of clinically meaningful indicators of distress and functional impairment among habitual caffeine users; we discuss the diagnostic criteria for Caffeine Use Disorder-a condition for further study included in the Diagnostic and Statistical Manual of Mental Disorders ( 5 th ed .); and we outline a research agenda to help guide future clinical, epidemiological, and genetic investigations of caffeine dependence. Numerous controlled laboratory investigations reviewed in this article show that caffeine produces behavioral and physiological effects similar to other drugs of dependence. Moreover, several recent clinical studies indicate that caffeine dependence is a clinically meaningful disorder that affects a nontrivial proportion of caffeine users. Nevertheless, more research is needed to determine the reliability, validity, and prevalence of this clinically important health problem.

Electronic Health Record (EHR) use in India is generally poor, and structured clinical information is mostly lacking. This work is the first attempt aimed at evaluating unstructured text mining for extracting relevant clinical information from Indian clinical records. We annotated a corpus of 250 discharge summaries from an Intensive Care Unit (ICU) in India, with markups for diseases, procedures, and lab parameters, their attributes, as well as key demographic information and administrative variables such as patient outcomes. In this process, we have constructed guidelines for an annotation scheme useful to clinicians in the Indian context. We evaluated the performance of an NLP engine, Cocoa, on a cohort of these Indian clinical records. We have produced an annotated corpus of roughly 90 thousand words, which to our knowledge is the first tagged clinical corpus from India. Cocoa was evaluated on a test corpus of 50 documents. The overlap F-scores across the major categories, namely disease/symptoms, procedures, laboratory parameters and outcomes, are 0.856, 0.834, 0.961 and 0.872 respectively. These results are competitive with results from recent shared tasks based on US records. The annotated corpus and associated results from the Cocoa engine indicate that unstructured text mining is a viable method for cohort analysis in the Indian clinical context, where structured EHR records are largely absent.

The Ling 6(HL) test offers a calibrated version of naturally produced speech sounds in dB HL for evaluation of detection thresholds. Aided performance has been previously characterized in adults. The purpose of this work was to evaluate and refine the Ling 6(HL) test for use in pediatric hearing aid outcome measurement. This work is presented across two studies incorporating an integrated knowledge translation approach in the characterization of normative and typical performance, and in the evaluation of clinical feasibility, utility, acceptability, and implementation. A total of 57 children, 28 normally hearing and 29 with binaural sensorineural hearing loss, were included in Study 1. Children wore their own hearing aids fitted using Desired Sensation Level v5.0. Nine clinicians from The Network of Pediatric Audiologists participated in Study 2. A CD-based test format was used in the collection of unaided and aided detection thresholds in laboratory and clinical settings; thresholds were measured clinically as part of routine clinical care. Confidence intervals were derived to characterize normal performance and typical aided performance according to hearing loss severity. Unaided-aided performance was analyzed using a repeated-measures analysis of variance. The audiologists completed an online questionnaire evaluating the quality, feasibility/executability, utility/comparative value/relative advantage, acceptability/applicability, and interpretability, in addition to recommendation and general comments sections. Ling 6(HL) thresholds were reliably measured with children 3-18 yr old. Normative and typical performance ranges were translated into a scoring tool for use in pediatric outcome measurement. In general, questionnaire respondents generally agreed that the Ling 6(HL) test was a high-quality outcome evaluation tool that can be implemented successfully in clinical settings. By actively collaborating with pediatric audiologists and using an integrated knowledge translation framework, this work supported the creation of an evidence-based clinical tool that has the potential to be implemented in, and useful to, clinical practice. More research is needed to characterize performance in alternative listening conditions to facilitate use with infants, for example. Future efforts focused on monitoring the use of the Ling 6(HL) test in daily clinical practice may help describe whether clinical use has been maintained across time and if any additional adaptations are necessary to facilitate clinical uptake.

Decision support tools increasingly integrate clinical knowledge such as medication indications and contraindications with electronic health record (EHR) data to support clinical care and patient safety. The availability of this encoded information and patient data provides an opportunity to develop measures of clinical decision complexity that may be of value for quality improvement and research efforts. We investigated the feasibility of using encoded clinical knowledge and EHR data to develop a measure of comorbidity interrelatedness (the degree to which patients' co-occurring conditions interact to generate clinical complexity). Using a common clinical scenario-decisions about blood pressure medications in patients with hypertension-we quantified comorbidity interrelatedness by calculating the number of indications and contraindications to blood pressure medications that are generated by patients' comorbidities (e.g., diabetes, gout, depression). We examined properties of comorbidity interrelatedness using data from a decision support system for hypertension in the Veterans Affairs Health Care System.

Salient findings and interpretations from the canimpact clinical cancer research study are visually represented in two synthesis maps for the purpose of communicating an integrated presentation of the study to clinical cancer researchers and policymakers. Synthesis maps integrate evidence and expertise into a visual narrative for knowledge translation and communication. A clinical system synthesis map represents the current Canadian primary care and cancer practice systems, proposed as a visual knowledge translation from the mixed-methods canimpact study to inform Canadian clinical research, policy, and practice discourses. Two synthesis maps, drawn together from multiple canimpact investigations and sources, were required to articulate critical differences between the clinical system and patient perspectives. The synthesis map of Canada-wide clinical cancer systems illustrates the relationships between primary care and the full cancer continuum. A patient-centred map was developed to represent the cancer (and primary care) journeys as experienced by breast and colorectal cancer patients.

Beside acquiring knowledge, medical students should also develop the ability to apply and reflect on it, requiring higher-order cognitive processing. Ideally, students should have reached higher-order cognitive processing when they enter the clinical program. Whether this is the case, is unknown. We investigated students' cognitive processing, and awareness of their knowledge during medical school. Data were gathered from 347 first-year preclinical and 196 first-year clinical students concerning the 2008 and 2011 Dutch progress tests. Questions were classified based upon Bloom's taxonomy: "simple questions" requiring lower and "vignette questions" requiring higher-order cognitive processing. Subsequently, we compared students' performance and awareness of their knowledge in 2008 to that in 2011 for each question type. Students' performance on each type of question increased as students progressed. Preclinical and first-year clinical students performed better on simple questions than on vignette questions. Third-year clinical students performed better on vignette questions than on simple questions. The accuracy of students' judgment of knowledge decreased over time. The progress test is a useful tool to assess students' cognitive processing and awareness of their knowledge. At the end of medical school, students achieved higher-order cognitive processing but their awareness of their knowledge had decreased.

Stress in dental students is well established with potential psychological distress, emotional exhaustion and burnout-related symptoms. Little attention has been given to the problems encountered by dental students during the transition from theoretical or paraclinical training to the clinical environment. The aim of this study was to adopt a qualitative research methods approach to understand the perceived stressors during students' clinical transition and provide insights for curriculum planners to enhance learning. This study analysed four groups of 2nd- and 3rd-year BDS students' experiences in focus group interviews relating to their pre-clinical and clinical transitions. The interviews were recorded and transcribed verbatim, and a thematic analysis was performed using an inductive qualitative approach. Key overlapping domains identified were the transition gap and stresses. The transition gap was subclassified into knowledge and skill (hard and soft), and stresses was subcategorised into internal and external stresses. On first coming to clinics, students experienced knowledge gaps of unfamiliar clinical treatments with mismatches between knowledge acquisition and clinical exposure. Students felt incompetent owing to the stresses attributable to curriculum design, staff and the patient. This negatively affected their confidence and clinical performance. A range of challenges have been identified that will allow curriculum designer's to plan a more supportive learning experience to help students during their transition to clinical practice giving them timely knowledge, confidence and clinical performance to better prepare them for entering clinics. © 2018 John Wiley & Sons A/S.

The high incidence of fatal diseases, inequitable access to health care, and socioeconomic disparities in India generate plentiful clinical bad news including diagnosis of a life-limiting disease, poor prognosis, treatment failure, and impending death. These contexts compel health care professionals to become the messengers of bad news to patients and their families. In global literature on breaking bad news, there is very little about such complex clinical interactions occurring in India or guiding health care providers to do it well. The purpose of this article is to identify the issues for future research that would contribute to the volume, comprehensiveness, and quality of empirical literature on breaking bad news in clinical settings across India. Towards this end, we have synthesized the studies done across the globe on breaking bad news, under four themes: (a) deciding the amount of bad news to deliver; (b) attending to cultural and ethical issues; (c) managing psychological distress; and (d) producing competent messengers of bad news. We believe that robust research is inevitable to build an indigenous knowledge base, enhance communicative competence among health care professionals, and thereby to improve the quality of clinical interactions in India.
Electronic cigarettes and nicotine clinical pharmacology.
Schroeder, Megan J; Hoffman, Allison C
2014-05-01
To review the available literature evaluating electronic cigarette (e-cigarette) nicotine clinical pharmacology in order to understand the potential impact of e-cigarettes on individual users, nicotine dependence and public health. Literature searches were conducted between 1 October 2012 and 30 September 2013 using key terms in five electronic databases. Studies were included in the review if they were in English and publicly available; non-clinical studies, conference abstracts and studies exclusively measuring nicotine content in e-cigarette cartridges were excluded from the review. Nicotine yields from automated smoking machines suggest that e-cigarettes deliver less nicotine per puff than traditional cigarettes, and clinical studies indicate that e-cigarettes deliver only modest nicotine concentrations to the inexperienced e-cigarette user. However, current e-cigarette smokers are able to achieve systemic nicotine and/or cotinine concentrations similar to those produced from traditional cigarettes. Therefore, user experience is critically important for nicotine exposure, and may contribute to the products' ability to support and maintain nicotine dependence. Knowledge about e-cigarette nicotine pharmacology remains limited. Because a user's e-cigarette experience may significantly impact nicotine delivery, future nicotine pharmacokinetic and pharmacodynamic studies should be conducted in experienced users to accurately assess the products' impact on public health.
“Evidence-Based Dentistry in Oral Surgery: Could We Do Better?”
Nocini, Pier Francesco; Verlato, Giuseppe; Frustaci, Andrea; de Gemmis, Antonio; Rigoni, Giovanni; De Santis, Daniele
2010-01-01
Evidence-based Dentistry (EBD), like Evidence-based Medicine (EBM), was born in order to seek the “best available research evidence” in the field of dentistry both in research and clinical routine. But evidence is not clearly measurable in all fields of healthcare: in particular, while drug effect is rather independent from clinician’s characteristics, the effectiveness of surgical procedures is strictly related to surgeon’s expertise, which is difficult to quantify. The research problems of dentistry have a lot in common with other surgical fields, where at the moment the best therapeutic recommendations and guidelines originates from an integration of evidence-based medicine and data from consensus conferences. To cope with these problems, new instruments have been developed, aimed at standardizing clinical procedures (CAD-CAM technology) and at integrating EBM achievements with the opinions of expert clinicians (GRADE System). One thing we have to remember however: it is necessary to use the instruments developed by evidence-based medicine but is impossible to produce sound knowledge without considering clinical expertise and quality of surgical procedures simultaneously. Only in this way we will obtain an evidence-based dentistry both in dental research and clinical practice, which is up to third millennium standards. PMID:20871758

The Bobath concept in contemporary clinical practice.
Graham, Julie Vaughan; Eustace, Catherine; Brock, Kim; Swain, Elizabeth; Irwin-Carruthers, Sheena
2009-01-01
Future development in neurorehabilitation depends upon bringing together the endeavors of basic science and clinical practice. The Bobath concept is widely utilized in rehabilitation following stroke and other neurological conditions. This concept was first developed in the 1950s, based on the neuroscience knowledge of those times. The theoretical basis of the Bobath concept is redefined based on contemporary neuroscience and rehabilitation science. The framework utilized in the Bobath concept for the analysis of movement and movement dysfunction is described. This framework focuses on postural control for task performance, the ability to move selectively, the ability to produce coordinated sequences of movement and vary movement patterns to fit a task, and the role of sensory input in motor behaviour and learning. The article describes aspects of clinical practice that differentiate this approach from other models of practice. Contemporary practice in the Bobath concept utilizes a problem-solving approach to the individual's clinical presentation and personal goals. Treatment is focused toward remediation, where possible, and guiding the individual towards efficient movement strategies for task performance. The aim of this article is to provide a theoretical framework on which future research into the Bobath concept can be based.

DNA-encoded chemical library technology was developed with the vision of its becoming a transformational platform for drug discovery. The hope was that a new paradigm for the discovery of low-molecular-weight drugs would be enabled by combining the vast molecular diversity achievable with combinatorial chemistry, the information-encoding attributes of DNA, the power of molecular biology, and a streamlined selection-based discovery process. Here, we describe the discovery and early clinical development of GSK2256294, an inhibitor of soluble epoxide hydrolase (sEH, EPHX2), by using encoded-library technology (ELT). GSK2256294 is an orally bioavailable, potent and selective inhibitor of sEH that has a long half life and produced no serious adverse events in a first-time-in-human clinical study. To our knowledge, GSK2256294 is the first molecule discovered from this technology to enter human clinical testing and represents a realization of the vision that DNA-encoded chemical library technology can efficiently yield molecules with favorable properties that can be readily progressed into high-quality drugs. © 2017 Wiley-VCH Verlag GmbH & Co.

Engaging Clinical Nurses in Quality Improvement Projects.
Moore, Susan; Stichler, Jaynelle F
2015-10-01
Clinical nurses have the knowledge and expertise required to provide efficient and proficient patient care. Time and knowledge deficits can prevent nurses from developing and implementing quality improvement or evidence-based practice projects. This article reviews a process for professional development of clinical nurses that helped them to define, implement, and analyze quality improvement or evidence-based practice projects. The purpose of this project was to educate advanced clinical nurses to manage a change project from inception to completion, using the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) Change Acceleration Process as a framework. One-to-one mentoring and didactic in-services advanced the knowledge, appreciation, and practice of advanced practice clinicians who completed multiple change projects. The projects facilitated clinical practice changes, with improved patient outcomes; a unit cultural shift, with appreciation of quality improvement and evidence-based projects; and engagement with colleagues. Project outcomes were displayed in poster presentations at a hospital exposition for knowledge dissemination. Copyright 2015, SLACK Incorporated.

To compare the effectiveness of team-based learning (TBL) to that of traditional lectures on learning outcomes in a therapeutics course sequence. A revised TBL curriculum was implemented in a therapeutic course sequence. Multiple choice and essay questions identical to those used to test third-year students (P3) taught using a traditional lecture format were administered to the second-year pharmacy students (P2) taught using the new TBL format. One hundred thirty-one multiple-choice questions were evaluated; 79 tested recall of knowledge and 52 tested higher level, application of knowledge. For the recall questions, students taught through traditional lectures scored significantly higher compared to the TBL students (88%±12% vs. 82%±16%, p=0.01). For the questions assessing application of knowledge, no differences were seen between teaching pedagogies (81%±16% vs. 77%±20%, p=0.24). Scores on essay questions and the number of students who achieved 100% were also similar between groups. Transition to a TBL format from a traditional lecture-based pedagogy allowed P2 students to perform at a similar level as students with an additional year of pharmacy education on application of knowledge type questions. However, P3 students outperformed P2 students regarding recall type questions and overall. Further assessment of long-term learning outcomes is needed to determine if TBL produces more persistent learning and improved application in clinical settings.
Optimizing care of residents with Parkinsonism in supervised facilities.

People with Parkinsonism (PWP) in residential facilities are usually elderly, cognitively impaired, physically disabled with poor quality of life and a high mortality rate. This paper aims to determine if the care of PWP in residential facilities could be improved by addressing staff knowledge on Parkinson related issues. A curriculum based on the Victorian Comprehensive Parkinson Program (VCPP) was developed and delivered to 118 staff members in 9 facilities across Melbourne. Measures of staff knowledge were undertaken at baseline, 1, 3 and 12 months. Data from a total of 49 residents were used in the analysis. Measures were taken at baseline, 1, 3 and 12 months included dementia screen (MMSE), geriatric depression scale (GDS), quality of life (PDQ39), fatigue (PDFS16), monthly falls diary, Unified Parkinson Disease Rating Scale (I,II,III) Hoehn & Yahr scale (H&Y) and resident/family questionnaire (RFQ) which focused on quality of care provision. It was found that the staff knowledge assessment scores (max = 37) significantly improved post education (P < 0.01) from baseline mean (11.1) and were maintained to 12 months mean (29.0). The residents group improved significantly for all measures at 1 month and these improvements were maintained up to 12 months (except for UPDRS III). This study demonstrated how a simple intervention, resulting in improved staff knowledge, produced a significant and clinically meaningful improvement in the care of PWP.

MO-C-9A-01: Effective Medical Physics Educational Activities: Models and Methods
DOE Office of Scientific and Technical Information (OSTI.GOV)
Sprawls, P
Medical physics is learned in a combination of activities including classroom sessions, individual study, small-group collaborative problem solving, and direct experience in the laboratory or clinical environment. Each type of learning activity is characterized by its effectiveness in producing the desired knowledge for the learner and the cost in terms of resources and human effort required providing it. While learning and teaching is a human activity, modern technology provides a variety of tools that can be used to enhance human performance. The class or conference room is the common setting for educational sessions in both academic institutions and continuing educationmore » conferences and programs such as those sponsored by the AAPM. A major value of a class/conference room program is efficiency by bringing a group of learners together to share in a common learning experience under the guidance of one or more experienced learning facilitators (lecturers or presenters). A major challenge is that the class/conference room is separated from the real world of medical physics. The design of an educational activity needs to take into consideration the desired outcomes with respect to what the learners should be able to do. The distinction is that of being able to apply the knowledge to perform specific physics functions rather than just knowing and being able to recall facts, and perhaps do well on written examinations. These are different types of knowledge structures within the human brain and distinctly different learning activities to develop each. Much of medical physics education, especially at the post-graduate and continuing education level, is for the purpose of enhancing the ability of physicists and other related professionals to perform applied procedures and tasks and requires specific types of knowledge.In this session we will analyze various learning activity models, the values and limitations of each, and how they can be used in medical physics education. An example we will use is optimizing CT image quality and dose which is an important topic for medical physicists, radiologists and residents, along with technologists. The knowledge structure for this is best developed by a combination of learning activities including class/conference discussions, individual study and review, and direct observation and interaction in the clinical setting under the direction of a knowledgeable leader.The function of the human brain will be considered with respect to learning experiences that contribute to effective medical physics knowledge structures. The characteristics of various types of educational activities will be compared with respect to their effectiveness for producing desired outcomes along with their limitations. Emphasis will be given to the design of highly-effective classroom/conference presentations, and activities will be demonstrated with an emphasis on using technology to enhance human performance of both learners and the learning facilitators. Learning Objectives: Develop and provide highly effective medical physics educational sessions. Use technology to enhance human performance in the educational process. Identify and analyze various models of educational activities Select and use educational activities that contribute value to the medical physics profession.« less

Knowing for Nursing Practice: Patterns of Knowledge and Their Emulation in Expert Systems
Abraham, Ivo L.; Fitzpatrick, Joyce J.
1987-01-01
This paper addresses the issue of clinical knowledge in nursing, and the feasibility of emulating this knowledge into expert system technology. The perspective on patterns of knowing for nursing practice, advanced by Carper (1978), serves as point of departure. The four patterns of knowing -- empirics, esthetics, ethics, personal knowledge -- are evaluated as to the extent to which they can be emulated in clinical expert systems, given constraints imposed by the current technology of these systems.
Data management in clinical research: An overview

Clinical Data Management (CDM) is a critical phase in clinical research, which leads to generation of high-quality, reliable, and statistically sound data from clinical trials. This helps to produce a drastic reduction in time from drug development to marketing. Team members of CDM are actively involved in all stages of clinical trial right from inception to completion. They should have adequate process knowledge that helps maintain the quality standards of CDM processes. Various procedures in CDM including Case Report Form (CRF) designing, CRF annotation, database designing, data-entry, data validation, discrepancy management, medical coding, data extraction, and database locking are assessed for quality at regular intervals during a trial. In the present scenario, there is an increased demand to improve the CDM standards to meet the regulatory requirements and stay ahead of the competition by means of faster commercialization of product. With the implementation of regulatory compliant data management tools, CDM team can meet these demands. Additionally, it is becoming mandatory for companies to submit the data electronically. CDM professionals should meet appropriate expectations and set standards for data quality and also have a drive to adapt to the rapidly changing technology. This article highlights the processes involved and provides the reader an overview of the tools and standards adopted as well as the roles and responsibilities in CDM. PMID:22529469
Automated interviews on clinical case reports to elicit directed acyclic graphs.
Luciani, Davide; Stefanini, Federico M
2012-05-01
Setting up clinical reports within hospital information systems makes it possible to record a variety of clinical presentations. Directed acyclic graphs (Dags) offer a useful way of representing causal relations in clinical problem domains and are at the core of many probabilistic models described in the medical literature, like Bayesian networks. However, medical practitioners are not usually trained to elicit Dag features. Part of the difficulty lies in the application of the concept of direct causality before selecting all the causal variables of interest for a specific patient. We designed an automated interview to tutor medical doctors in the development of Dags to represent their understanding of clinical reports. Medical notions were analyzed to find patterns in medical reasoning that can be followed by algorithms supporting the elicitation of causal Dags. Clinical relevance was defined to help formulate only relevant questions by driving an expert's attention towards variables causally related to nodes already inserted in the graph. Key procedural features of the proposed interview are described by four algorithms. The automated interview comprises questions on medical notions, phrased in medical terms. The first elicitation session produces questions concerning the patient's chief complaints and the outcomes related to diseases serving as diagnostic hypotheses, their observable manifestations and risk factors. The second session focuses on questions that refine the initial causal paths by considering syndromes, dysfunctions, pathogenic anomalies, biases and effect modifiers. A case study concerning a gastro-enterological problem and one dealing with an infected patient illustrate the output produced by the algorithms, depending on the answers provided by the doctor. The proposed elicitation framework is characterized by strong consistency with medical background and by a progressive introduction of relevant medical topics. Revision and testing of the subjectively elicited Dag is performed by matching the collected answers with the evidence included in accepted sources of biomedical knowledge.

Research on cancer epigenetics has flourished in the last decade. Nevertheless growing evidence point on the importance to understand the mechanisms by which epigenetic changes regulate the genesis and progression of cancer growth. Several epigenetic targets have been discovered and are currently under validation for new anticancer therapies. Drug discovery approaches aiming to target these epigenetic enzymes with small-molecules inhibitors have produced the first pre-clinical and clinical outcomes and many other compounds are now entering the pipeline as new candidate epidrugs. The most studied targets can be ascribed to histone deacetylases and DNA methyltransferases, although several other classes of enzymes are able to operate post-translational modifications to histone tails are also likely to represent new frontiers for therapeutic interventions. By acknowledging that the field of cancer epigenetics is evolving with an impressive rate of new findings, with this review we aim to provide a current overview of pre-clinical applications of small-molecules for cancer pathologies, combining them with the current knowledge of epigenetic targets in terms of available structural data and drug design perspectives.

Organ donation as transition work: Policy discourse and clinical practice in The Netherlands.
Paul, Katharina T; Avezaat, Cees J J; Ijzermans, Jan N; Friele, Roland D; Bal, Roland A
2014-07-01
An increasing number of patients become eligible for organ transplants. In the Netherlands, at the level of policy discourse, growing waiting lists are often referred to as a persistent "shortage" of organs, producing a "public health crisis." In this way, organ donation is presented as an ethical, social, and medical necessity. Likewise, policy discourse offers a range of seemingly unambiguous solutions: improving logistical infrastructure at the level of hospitals, developing organizational and legal protocols, as well as public information campaigns. Instead of taking these problem and solution definitions as given, we critically examine the relationship between policy discourse and clinical practice. Based on a historical review, first, we trace the key moments of transformation where organ donation became naturalized in Dutch policy discourse, particularly in its altruistic connotation. Second, based on in-depth interviews with medical professionals, we show how those involved in organ donation continue to struggle with the controversial nature of their clinical practice. More specifically, we highlight their use of different forms of knowledge that underlie clinicians' "transition work": from losing a patient to "gaining" a donor. © The Author(s) 2013.
What do we (not) know about how paracetamol (acetaminophen) works?
Toussaint, K; Yang, X C; Zielinski, M A; Reigle, K L; Sacavage, S D; Nagar, S; Raffa, R B
2010-12-01
Although paracetamol (acetaminophen), N-(4-Hydroxyphenyl)acetamide, is one of the world's most widely used analgesics, the mechanism by which it produces its analgesic effect is largely unknown. This lack is relevant because: (i) optimal pain treatment matches the analgesic mechanism to the (patho)physiology of the pain and (ii) modern drug discovery relies on an appropriate screening assay. To review the clinical profile and preclinical studies of paracetamol as means of gaining insight into its mechanism of analgesic action. A literature search was conducted of clinical and preclinical literature and the information obtained was organized and reviewed from the perspective of its contribution to an understanding of the mechanism of analgesic action of paracetamol. Paracetamol's broad spectrum of analgesic and other pharmacological actions is presented, along with its multiple postulated mechanism(s) of action. No one mechanism has been definitively shown to account for its analgesic activity. Further research is needed to uncover the mechanism of analgesic action of paracetamol. The lack of this knowledge affects optimal clinical use and impedes drug discovery efforts. © 2010 The Authors. JCPT © 2010 Blackwell Publishing Ltd.
Principles and practice of external digital photography in ophthalmology
Mukherjee, Bipasha; Nair, Akshay Gopinathan
2012-01-01
It is mandatory to incorporate clinical photography in an ophthalmic practice. Patient photographs are routinely used in teaching, presentations, documenting surgical outcomes and marketing. Standardized clinical photographs are part of an armamentarium for any ophthalmologist interested in enhancing his or her practice. Unfortunately, many clinicians still avoid taking patient photographs for want of basic knowledge or inclination. The ubiquitous presence of the digital camera and digital technology has made it extremely easy and affordable to take high-quality images. It is not compulsory to employ a professional photographer or invest in expensive equipment any longer for this purpose. Any ophthalmologist should be able to take clinical photographs in his/her office settings with minimal technical skill. The purpose of this article is to provide an ophthalmic surgeon with guidelines to achieve standardized photographic views for specific procedures, to achieve consistency, to help in pre-operative planning and to produce accurate pre-operative and post-operative comparisons, which will aid in self-improvement, patient education, medicolegal documentation and publications. This review also discusses editing, storage, patient consent, medicolegal issues and importance of maintenance of patient confidentiality. PMID:22446907
Pharmacotherapy and motor recovery after stroke.
Viale, Luciano; Catoira, Natalia Paola; Di Girolamo, Guillermo; González, Claudio Daniel
2018-01-01
Stroke is one of the most prevalent neurological diseases worldwide, especially among the elderly population. There are various mechanisms that enhance motor recovery after a stroke. In clinical practice, we have the opportunity to enhance plasticity by designing specific rehabilitation programs. Areas covered: There are a variety of drugs commonly administered to people after the acute phase of a stroke. These drugs may modify motor performance. Herein reviewed is the evidence concerning motor enhancement or decline in stroke patients, produced by drugs commonly used in rehabilitation settings. An extensive review of animal and human studies is performed. Expert commentary: Many of the clinical trials carried out were underpowered. Modest evidence supports the claim that there are agents that can affect motor rehabilitation after a stroke. Amphetamine-like agents, serotonin reuptake inhibitors, and levodopa might improve motor outcomes, while antipsychotics, some antiepileptic drugs, and GABAmimetic drugs could impair the recovery process. To draw definite recommendations, more comprehensive knowledge about the efficacy, long-term effects, and safety of these drugs is required. There are also other interesting molecules that open a promising field for basic and clinical research, in the search for new therapeutic options.

Intuition: A Concept Analysis.
Chilcote, Deborah R
2017-01-01
The purpose of this article is to conceptually examine intuition; identify the importance of intuition in nursing education, clinical practice, and patient care; encourage acceptance of the use of intuition; and add to the body of nursing knowledge. Nurses often report using intuition when making clinical decisions. Intuition is a rapid, unconscious process based in global knowledge that views the patient holistically while synthesizing information to improve patient outcomes. However, with the advent of evidence-based practice (EBP), the use of intuition has become undervalued in nursing. Walker and Avant's framework was used to analyze intuition. A literature search from 1987 to 2014 was conducted using the following keywords: intuition, intuition and nursing, clinical decision making, clinical decision making and intuition, patient outcomes, EBP, and analytical thinking. The use of intuition is reported by nurses, but is not legitimized within the nursing profession. Defining attributes of intuition are an unconscious, holistic knowledge gathered without using an analytical process and knowledge derived through synthesis, not analysis. Consequences include verification of intuition through an analytical process and translating that knowledge into a course of action. This article supports the use of intuition in nursing by offering clarity to the concept, adds to the nursing knowledge base, encourages a holistic view of the patient during clinical decision making, and encourages nurse educators to promote the use of intuition. © 2016 Wiley Periodicals, Inc.

Schizophrenia is a complex disorder, and the knowledge about it can have a positive impact. The purpose of this study was to make the translation and cultural adaptation of the Knowledge About Schizophrenia Test (KAST) into Portuguese and determine the influence of clinical and socio-demographic factors on knowledge. The test was applied to 189 caregivers of patients enrolled in Schizophrenia Program of the Federal University of São Paulo, 30 caregivers of clinical patients of the General Outpatient Clinic of the same University, and 30 health professionals. The face and content validity of the test was established. The mean value (SD) obtained with the application of the final version to caregivers of schizophrenic patients was 12.96 (2.45) - maximum 17. Level of knowledge increased considering the following order: caregivers of clinical patients, caregivers of patients with schizophrenia and mental health professionals. The intraclass correlation coefficient (0.592) obtained in the test-retest was statistically significant. An influence of social class, race, gender and education of the caregiver on the test was observed, and the last two factors were more relevant. The KAST translated and adapted into Portuguese is a valid instrument and can be used as an evaluation tool on psychoeducational interventions. Copyright © 2015 Elsevier B.V. All rights reserved.
[Relationships with microbiology: the view from other specialties].
Santiago, Emilio Bouza; Garau, Javier; Crespo, Rafael Zaragoza; Gonzalo de Liria, Carlos Rodrigo
2010-10-01
The major advances produced in infectious diseases, partly favored by technological development in the last few years, together with current changes in healthcare, have led to a new scenario in which, far from the control of infectious diseases, clinical microbiology has acquired an undoubted leading role. This new panorama implies collaboration among distinct health professionals within the same healthcare setting, with common and occasionally conflicting interests. Setting aside the individual differences that can be produced in the daily life of our hospitals, all health professionals should understand one another, not only because such cooperation is required for optimal patient care but also because synergistic collaboration among professions would improve professional development. Based on this principle of a multidisciplinary approach, collaboration and mutual respect, the moment seems opportune for the various professionals involved in infectious diseases (infectologists, internists, pediatricians and intensivists) to express their view of the specialty of clinical microbiology. The present article includes reflections, from a highly liberal and personal point of view, on how mutual relationships can be approached and on how greater knowledge of infectious diseases can continue to be gained in Spain. In all these reflections, the questions of where we come from and where we are going are explicit or implicit. Copyright © 2010 Elsevier España S.L. All rights reserved.

Objective To assess the feasibility, acceptability and changes in knowledge among cancer patients assigned to receive a 160 page book on experimental cancer therapies and clinical trials. Methods We enrolled 20 patients with cancer who had never participated in a clinical trial, and randomly assigned them to receive the book either during Week 1or Week 4 of the study. We collected baseline patient demographic and cancer related information as well as knowledge about cancer clinical trials at Week 0. Follow-up surveys were administered at Weeks 3 and 6 for both study groups. Comparisons were made within and between groups randomized to receive the book Early (at Week 1) to those who received it Later (at Week 4). Results One hundred percent of data were captured in both groups at baseline, which decreased to 77.8% by Week 6. The vast majority of participants found the book moderately or very useful (89% in the Early Group at Week 3 and 95.5% in the Late Group at Week 6). Within group pair-wise comparisons found significant difference between baseline and Week 6 in content-specific knowledge scores among participants in the Late Group (79% vs. 92.1%, p=0.01). Global knowledge scores increased significantly for variables reflecting knowledge that promotes decisions to participate in clinical trials. Conclusions Providing published reading material to patients with cancer is both feasible and acceptable. Offering information to patients about cancer clinical trials, using a book designed for patients with cancer may influence knowledge related to decision to participate in clinical trials.

Advancements in informatics in radiotherapy are opening up opportunities to improve our ability to assess treatment plans. Models on individualizing patient dose constraints from prior patient data and shape relationships have been extensively researched and are now making their way into commercial products. New developments in knowledge based treatment planning involve understanding the impact of the radiation dosimetry on the patient. Akin to radiobiology models that have driven intensity modulated radiotherapy optimization, toxicity and outcome predictions based on treatment plans and prior patient experiences may be the next step in knowledge based planning. In order to realize these predictions, itmore » is necessary to understand how the clinical information can be captured, structured and organized with ontologies and databases designed for recall. Large databases containing radiation dosimetry and outcomes present the opportunity to evaluate treatment plans against predictions of toxicity and disease response. Such evaluations can be based on dose volume histogram or even the full 3-dimensional dose distribution and its relation to the critical anatomy. This session will provide an understanding of ontologies and standard terminologies used to capture clinical knowledge into structured databases; How data can be organized and accessed to utilize the knowledge in planning; and examples of research and clinical efforts to incorporate that clinical knowledge into planning for improved care for our patients. Learning Objectives: Understand the role of standard terminologies, ontologies and data organization in oncology Understand methods to capture clinical toxicity and outcomes in a clinical setting Understand opportunities to learn from clinical data and its application to treatment planning Todd McNutt receives funding from Philips, Elekta and Toshiba for some of the work presented.« less
More than Anecdotes: Fishers' Ecological Knowledge Can Fill Gaps for Ecosystem Modeling.
Bevilacqua, Ana Helena V; Carvalho, Adriana R; Angelini, Ronaldo; Christensen, Villy
2016-01-01
Ecosystem modeling applied to fisheries remains hampered by a lack of local information. Fishers' knowledge could fill this gap, improving participation in and the management of fisheries. The same fishing area was modeled using two approaches: based on fishers' knowledge and based on scientific information. For the former, the data was collected by interviews through the Delphi methodology, and for the latter, the data was gathered from the literature. Agreement between the attributes generated by the fishers' knowledge model and scientific model is discussed and explored, aiming to improve data availability, the ecosystem model, and fisheries management. The ecosystem attributes produced from the fishers' knowledge model were consistent with the ecosystem attributes produced by the scientific model, and elaborated using only the scientific data from literature. This study provides evidence that fishers' knowledge may suitably complement scientific data, and may improve the modeling tools for the research and management of fisheries.
Abnormal appearances: inspection, display and the clinic.
Featherstone, Katie; Atkinson, Paul
2014-01-01
We provide an examination of the field of dysmorphology, a clinical speciality that in its current form combines a long history of inspection and display with the identification and representation of associated underlying molecular changes. The recognition and description of abnormal appearances is thus increasingly accompanied by genetic and other molecular investigations. Our analysis draws on our long-term ethnographic engagement with a UK clinical genetics service and the work of two clinical genetics teams within a regional teaching hospital. We document the intersection of genetic science with clinical work to suggest that while molecular testing often identifies the genetic basis for unusual appearances and abnormal development, it does not fully supplant clinical apperception and interpretation. The two modes of knowledge--the clinical and the biomedical--co-exist in the work and the discourse of dysmorphology practice. The contemporary dysmorphology clinic thus encapsulates the epistemological systems of modern medicine, grounded in the clinical gaze and on the classificatory systems of classic nosology. Within such a system of clinical knowledge, the 'monstrous' does not escape the boundaries of knowledge. Monstrous appearances are accommodated and domesticated within the classificatory systems of normal medicine.
A multidisciplinary approach to reducing spurious hyperkalemia in hospital outpatient clinics.
Loh, Tze Ping; Sethi, Sunil K
2015-10-01
To describe a multidisciplinary effort to investigate and reduce the occurence of outpatient spurious hyperkalaemia. Spurious hyperkalemia is a falsely elevated serum potassium result that does not reflect the in vivo condition of a person. A common practice of fist clenching/pumping during phlebotomy to improve vein visualisation is an under-appreciated cause of spurious hyperkalemia. Pre- and postinterventional study. Objective evidence of spurious hyperkalaemia was sought by reviewing archived laboratory results. A literature review was undertaken to summarise known causes of spurious hyperkalaemia and develop a best practice in phlebotomy. Subsequently, nurses from the Urology Clinic were interviewed, observed and surveyed to understand their phlebotomy workflow and identify potential areas of improvement by comparing to the best practice in phlebotomy. Unexplained (potentially spurious) hyperkalaemia was defined as a serum potassium of >5·0 mmol/l in a patient without stage 5 chronic kidney disease or haemolysed blood sample. Nurses from the Urology Clinic showed significant knowledge gap regarding causes of spurious hyperkalaemia when compared to the literature review. Direct observation revealed patients were routinely asked to clench their fists, which may cause spurious hyperkalaemia. Following these observations, several educational initiatives were administered to address the knowledge gap and stop fist clenching. The rate of unexplained hyperkalaemia at the Urology clinic reduced from a baseline of 16·0-3·8%, 58 weeks after intervention. Similar education intervention was propagated to all 18 other specialist outpatient clinic locations, which saw their rate of unexplained hyperkalaemia decrease from 5·4 to 3·7%. To ensure sustainability of the improvements, the existing phlebotomy standard operating protocol, educational and competency testing materials at variance with the best practice were revised. A simple intervention of avoiding fist clenching/pumping during phlebotomy produced significant reduction in the rate of spurious hyperkalemia. © 2015 John Wiley & Sons Ltd.

[Research applications in digital radiology. Big data and co].
Müller, H; Hanbury, A
2016-02-01
Medical imaging produces increasingly complex images (e.g. thinner slices and higher resolution) with more protocols, so that image reading has also become much more complex. More information needs to be processed and usually the number of radiologists available for these tasks has not increased to the same extent. The objective of this article is to present current research results from projects on the use of image data for clinical decision support. An infrastructure that can allow large volumes of data to be accessed is presented. In this way the best performing tools can be identified without the medical data having to leave secure servers. The text presents the results of the VISCERAL and Khresmoi EU-funded projects, which allow the analysis of previous cases from institutional archives to support decision-making and for process automation. The results also represent a secure evaluation environment for medical image analysis. This allows the use of data extracted from past cases to solve information needs occurring when diagnosing new cases. The presented research prototypes allow direct extraction of knowledge from the visual data of the images and to use this for decision support or process automation. Real clinical use has not been tested but several subjective user tests showed the effectiveness and efficiency of the process. The future in radiology will clearly depend on better use of the important knowledge in clinical image archives to automate processes and aid decision-making via big data analysis. This can help concentrate the work of radiologists towards the most important parts of diagnostics.
Preparing for the primary care clinic: an ambulatory boot camp for internal medicine interns

Introduction Internal medicine (IM) interns start continuity clinic with variable ambulatory training. Multiple other specialties have utilized a boot camp style curriculum to improve surgical and procedural skills, but boot camps have not been used to improve interns’ ambulatory knowledge and confidence. The authors implemented and assessed the impact of an intern ambulatory boot camp pilot on primary care knowledge, confidence, and curricular satisfaction. Methods During July 2014, IM interns attended ambulatory boot camp. It included clinically focused case-based didactic sessions on common ambulatory topics as well as orientation to the clinic and electronic medical records. Interns anonymously completed a 15-question pre-test on topics covered in the boot camp as well as an identical post-test after the boot camp. The interns were surveyed regarding their confidence and satisfaction. Results Thirty-eight interns participated in the boot camp. Prior to the boot camp, few interns reported confidence managing common outpatient conditions. The average pre-test knowledge score was 46.3%. The average post-test knowledge score significantly improved to 76.1% (p<0.001). All interns reported that the boot camp was good preparation for clinics and 97% felt that the boot camp boosted their confidence. Conclusions The ambulatory boot camp pilot improved primary care knowledge, and interns thought it was good preparation for clinic. The ambulatory boot camp was well received and may be an effective way to improve the preparation of interns for primary care clinic. Further assessment of clinical performance and expansion to other programs and specialties should be considered. PMID:26609962

This study's objective is to develop and use a scalable genuine technology platform for clinical decision support based on Arden Syntax, which was extended by fuzzy set theory and fuzzy logic. Arden Syntax is a widely recognized formal language for representing clinical and scientific knowledge in an executable format, and is maintained by Health Level Seven (HL7) International and approved by the American National Standards Institute (ANSI). Fuzzy set theory and logic permit the representation of knowledge and automated reasoning under linguistic and propositional uncertainty. These forms of uncertainty are a common feature of patients' medical data, the body of medical knowledge, and deductive clinical reasoning.
Building a Knowledge to Action Program in Stroke Rehabilitation.
Janzen, Shannon; McIntyre, Amanda; Richardson, Marina; Britt, Eileen; Teasell, Robert
2016-09-01
The knowledge to action (KTA) process proposed by Graham et al (2006) is a framework to facilitate the development and application of research evidence into clinical practice. The KTA process consists of the knowledge creation cycle and the action cycle. The Evidence Based Review of Stroke Rehabilitation is a foundational part of the knowledge creation cycle and has helped guide the development of best practice recommendations in stroke. The Rehabilitation Knowledge to Action Project is an audit-feedback process for the clinical implementation of best practice guidelines, which follows the action cycle. The objective of this review was to: (1) contextualize the Evidence Based Review of Stroke Rehabilitation and Rehabilitation Knowledge to Action Project within the KTA model and (2) show how this process led to improved evidence-based practice in stroke rehabilitation. Through this process, a single centre was able to change clinical practice and promote a culture that supports the use of evidence-based practices in stroke rehabilitation.

Universities are increasingly regarded as key actors in the new 'knowledge economy', with requirements to produce market-oriented knowledge and engage in commercialization. This is of particular significance in the biomedical field, reflecting the perceived gap between success in terms of scientific discoveries and its transformation into products. The dominant discourse attributes this situation to 'blocks' in the translational pathway from 'bench to bedside', leading to policies to 'reengineer' the research enterprise. This study examines a pilot initiative established by the UK's Medical Research Council (MRC). This involved employing a change agent (Research Translator) supported by a small amount of translational funding to promote the culture and practice of translational research at a university/hospital site in England. An ethnographically informed case study involving semi-structured and open exploratory interviews, observation and document review, was conducted in 2008. Analysis and interpretation were informed by Bourdieu's logic of practice applied to science. The requirements of translational research promoted by the Research Translator and its sources of capital (authority, prestige etc) were largely congruent with the 'field' of clinical science. In contrast, translational research diverged from perceptions of 'legitimate' science and requirements for capital accumulation held by the majority of basic scientists who often described this research as 'high risk' and were resistant to the Research Translator's advice. However some differences in motivations and practices were identified within groups of scientists associated with career stage, work environment and specialty. We argue that there are convergent and divergent forces that influence scientists' readiness to adopt a market-oriented translational research model and in turn facilitate or constrain the effectiveness of a knowledge broker. We also identify ways in which current structures and policies continue to promote a continuum of forms of knowledge production, thus challenging notions of a linear shift.

Little is known about the degree of utilization of information resources on diabetes by general practitioners (GPs) and its impact on their clinical behavior in developing countries. Such information is vital if GPs' diabetes knowledge is to be improved. This cross-sectional study recruited 319 GPs in the summer of 2008. Questions were about the updates on diabetes knowledge in the previous two years, utilization of information resources (domestic and foreign journals, congresses, the Internet, reference books, mass media, and peers), attitude toward the importance of each resource, and impact of each resource on clinical behavior. A total of 62% of GPs had used information resources for improving their knowledge on diabetes in the previous two years. Domestic journals accounted for the highest utilization (30%) and the highest importance score (83 points from 100); with the importance score not being affected by sex, years elapsed after graduation, and numbers of diabetic visits. Clinical behavior was not influenced by the information resources listed; whereas knowledge upgrade, irrespective of the sources utilized, had a significantly positive correlation with clinical behavior. Domestic journals constituted the main information resource utilized by the GPs; this resource, however, in tandem with the other information resources on diabetes exerted no significant impact on the GPs' clinical behavior. In contrast to the developed countries, clinical guidelines do not have any place as a source of information and or practice. Indubitably, the improvement of diabetes knowledge transfer requires serious interventions to improve information resources as well as the structure of scientific gatherings and collaborations.

The Hegemonic Medical Model is discussed and is articulated with the postulates of the sociology of the professions. The information takes Aids as a specific topic, because it involves the aspects of recent scientific development, of clinical and epidemiological importance and due to the research which is being done for its treatment and the production of immunizations. This is a case study of students enrolled in different years of study for medical degrees at the three main universities in México City. A closed-question questionnaire was handed out, checked and corrected, the variables of which were related to three types of knowledge, that is, basic, technical and general. The students were revealed to master this subject to only a minor extent the extensions of the knowledge of the disciplines of the profession however being applied to new cases without the suitable accuracy. A certain degree of dissociation was found to exist among the different types of knowledge which were researched, the professional know-how having been noted to clearly conform within specialized, segmented, curative logic of the Hegemonic Medical Model. The technical, problem-solving knowledge employed in clinical use prevails over the systematic, abstract knowledge of the general knowledge of medicine. A clear notion of the processes based on the dominant medical pattern is revealed in the single-causal relations of the disease. There is an extension of the basic knowledge a the resolving of clinical problems. The medical students are oriented toward taking in knowledge which will be useful to them in clinical practice.
Diagnosis demystified: CT as diagnostic tool in endodontics

Diagnosis in endodontics is usually based on clinical and radiographical presentations, which are only empirical methods. The role of healing profession is to apply knowledge and skills towards maintaining and restoring the patient's health. Recent advances in imaging technologies have added to correct interpretation and diagnosis. CT is proving to be an effective tool in solving endodontic mysteries through its three-dimensional visualisation. CT imaging offers many diagnostic advantages to produce reconstructed images in selected projection and low-contrast resolution far superior to that of all other X-ray imaging modalities. This case report is an endeavour towards effective treatment planning of cases with root fracture, root resorption using spiral CT as an adjuvant diagnostic tool. PMID:23814212

Parathormone (PTH), produced by parathyroid glands, is the main regulator of calcium homeostasis. Hypoparathyroidism (hypoPT), due to decrease of PTH production, is a rare disease. Symptoms are multiple, altering function of several organs and leading to a decrease of quality of life. Acquired etiologies, including thyroïdectomy, the main cause of hypoPT, can be distinguished from congenital etiologies, including genetic defects. HypoPT, which is classically treated by supplementation by calcium and active vitamin D, can now be treated by recombinant injection in certain indications as a poor control under classical therapy. Here are summarized current knowledge on etiologies, epidemiology, clinical manifestations and management of hypoPT. © 2017 Elsevier Masson SAS. Tous droits réservés.

Ambulatory Morning Report: A Case-Based Method of Teaching EBM Through Experiential Learning.
Luciano, Gina L; Visintainer, Paul F; Kleppel, Reva; Rothberg, Michael B
2016-02-01
Evidence-based medicine (EBM) skills are important to daily practice, but residents generally feel unskilled incorporating EBM into practice. The Kolb experiential learning theory, as applied to curricular planning, offers a unique methodology to help learners build an EBM skill set based on clinical experiences. We sought to blend the learner-centered, case-based merits of the morning report with an experientially based EBM curriculum. We describe and evaluate a patient-centered ambulatory morning report combining the User's Guides to the Medical Literature approach to EBM and experiential learning theory in the internal medicine department at Baystate Medical Center. The Kolb experiential learning theory postulates that experience transforms knowledge; within that premise we designed a curriculum to build EBM skills incorporating residents' patient encounters. By developing structured clinical questions based on recent clinical problems, residents activate prior knowledge. Residents acquire new knowledge through selection and evaluation of an article that addresses the structured clinical questions. Residents then apply and use new knowledge in future patient encounters. To assess the curriculum, we designed an 18-question EBM test, which addressed applied knowledge and EBM skills based on the User's Guides approach. Of the 66 residents who could participate in the curriculum, 61 (92%) completed the test. There was a modest improvement in EBM knowledge, primarily during the first year of training. Our experiential curriculum teaches EBM skills essential to clinical practice. The curriculum differs from traditional EBM curricula in that ours blends experiential learning with an EBM skill set; learners use new knowledge in real time.
Practice-Based Knowledge Discovery for Comparative Effectiveness Research: An Organizing Framework
Lucero, Robert J.; Bakken, Suzanne
2014-01-01
Electronic health information systems can increase the ability of health-care organizations to investigate the effects of clinical interventions. The authors present an organizing framework that integrates outcomes and informatics research paradigms to guide knowledge discovery in electronic clinical databases. They illustrate its application using the example of hospital acquired pressure ulcers (HAPU). The Knowledge Discovery through Informatics for Comparative Effectiveness Research (KDI-CER) framework was conceived as a heuristic to conceptualize study designs and address potential methodological limitations imposed by using a single research perspective. Advances in informatics research can play a complementary role in advancing the field of outcomes research including CER. The KDI-CER framework can be used to facilitate knowledge discovery from routinely collected electronic clinical data. PMID:25278645

Taxonomy development and knowledge representation of nurses' personal cognitive artifacts.
McLane, Sharon; Turley, James P
2009-11-14
Nurses prepare knowledge representations, or summaries of patient clinical data, each shift. These knowledge representations serve multiple purposes, including support of working memory, workload organization and prioritization, critical thinking, and reflection. This summary is integral to internal knowledge representations, working memory, and decision-making. Study of this nurse knowledge representation resulted in development of a taxonomy of knowledge representations necessary to nursing practice.This paper describes the methods used to elicit the knowledge representations and structures necessary for the work of clinical nurses, described the development of a taxonomy of this knowledge representation, and discusses translation of this methodology to the cognitive artifacts of other disciplines. Understanding the development and purpose of practitioner's knowledge representations provides important direction to informaticists seeking to create information technology alternatives. The outcome of this paper is to suggest a process template for transition of cognitive artifacts to an information system.
Medical and psychology students' knowledge and attitudes regarding aging and sexuality.
Snyder, Rachel J; Zweig, Richard A
2010-01-01
The current study surveys medical and doctoral psychology students (N = 100) from an urban northeastern university regarding knowledge and attitudes toward elderly sexuality and aging using the Facts on Aging Quiz, the Aging Sexuality Knowledge and Attitudes Scale, and measures of interest in gerontology, academic/clinical exposure to aging and sexuality, and contact with elders. The current study found that psychology students demonstrated greater aging knowledge than medical students; however, both groups showed gaps in knowledge about sexuality. Married students had greater academic/clinical exposure and greater knowledge about aging but less permissive attitudes toward elderly sexuality. Generally, knowledge about aging was the strongest correlate of knowledge about sexuality. Level of knowledge about sexuality was not associated with attitudes. Attitudes toward sexuality and aging may be more strongly tied to demographic variables reflective of religious beliefs or adherence to sociocultural norms.

Written and clinical tests compared the change in clinical knowledge and practical clinical skill of first-year dental students watching a clinical video recording of the three-step etch-and-rinse resin bonding system to those using an interactive dental video game teaching the same procedure. The research design was a randomized controlled trial with eighty first-year dental students enrolled in the preclinical operative dentistry course. Students' change in knowledge was measured through written examination using a pre-test and a post-test, as well as clinical tests in the form of a benchtop shear bond strength test. There was no statistically significant difference between teaching methods in regards to change in either knowledge or clinical skills, with one minor exception relating to the wetness of dentin following etching. Students expressed their preference for an interactive self-paced method of teaching.

Clinicians and clinical researchers often seek information in electronic health records (EHRs) that are relevant to some concept of interest, such as a disease or finding. The heterogeneous nature of EHRs can complicate retrieval, risking incomplete results. We frame this problem as the presence of two gaps: 1) a gap between clinical concepts and their representations in EHR data and 2) a gap between data representations and their locations within EHR data structures. We bridge these gaps with a knowledge structure that comprises relationships among clinical concepts (including concepts of interest and concepts that may be instantiated in EHR data) and relationships between clinical concepts and the database structures. We make use of available knowledge resources to develop a reproducible, scalable process for creating a knowledge base that can support automated query expansion from a clinical concept to all relevant EHR data.
Student-Run Clinics: A Novel Approach to Integrated Care, Teaching and Recruitment.
Mishan, Liza I; Dragatsi, Dianna
2017-05-01
The purpose of this study is to assess the educational impact of incorporating a psychiatry consult service into a medical student-run clinic. In November 2014, a psychiatry consult service was introduced at the Columbia-Harlem Homeless Medical Partnership (CHHMP), a student-run clinic located in Harlem, New York. From September 2015 to January 2016, surveys (Qualtrics) were then distributed to student members of the clinic. Surveys assessed how the psychiatric consult service impacted students' knowledge, skills and attitudes about psychiatry. According to survey results (83.8% response rate, n = 31), 100% of students at CHHMP agreed that the psychiatry consult service is a useful addition to the clinic, and 94% agreed that the service helped increase their perceived knowledge of psychiatry. Survey results suggest that having a psychiatry consult service at a student-run clinic is a beneficial educational model in increasing medical students' perceived knowledge and comfort with psychiatry.

Culturally secure health care settings enhance accessibility by Aboriginal Australians and improve their satisfaction with service delivery. A culturally secure health service recognises and responds to the legitimate cultural rights of the recipients of care. Focus is upon the health care system as well as the practice and behaviours of the individuals within it. In an attempt to produce culturally secure practitioners, the inclusion of Aboriginal content in health professional programs at Australian universities is now widespread. Studies of medical students have identified the positive impact of this content on knowledge and attitudes towards Aboriginal people but relatively little is known about the responses of students in other health professional education programs. This study explored undergraduate midwifery students' knowledge and attitudes towards Aboriginal people, and the impact of Aboriginal content in their program. The study surveyed 44 students who were in their first, second and third years of a direct entry, undergraduate midwifery program at a Western Australian (WA) university. The first year students were surveyed before and after completion of a compulsory Aboriginal health unit. Second and third year students who had already completed the unit were surveyed at the end of their academic year. Pre- and post-unit responses revealed a positive shift in first year students' knowledge and attitudes towards Aboriginal people and evidence that teaching in the unit was largely responsible for this shift. A comparison of post-unit responses with those from students in subsequent years of their program revealed a significant decline in knowledge about Aboriginal issues, attitudes towards Aboriginal people and the influence of the unit on their views. Despite this, all students indicated a strong interest in more clinical exposure to Aboriginal settings. The inclusion of a unit on Aboriginal health in an undergraduate midwifery program has been shown to enhance knowledge and shift attitudes towards Aboriginal people in a positive direction. These gains may not be sustained, however, without vertical integration of content and reinforcement throughout the program. Additional midwifery-specific Aboriginal content related to pregnancy and birthing, and recognition of strong student interest in clinical placements in Aboriginal settings provide opportunities for future curriculum development.

Introduction: Physician adherence to guideline recommendations regarding the provision of counseling and support for smokers willing to quit is low. A lack of training during undergraduate medical education has been identified as a potential cause. This prospective intervention study evaluated a novel teaching module for medical students. Methods: As part of a 6-week cardiovascular course, 125 fourth-year undergraduate medical students received a multimodal and interactive teaching module on smoking cessation, including online learning material, lectures, seminars, and practical skills training. Short- and medium-term effects on knowledge, skills, attitudes, and self-reported practice were measured using written examinations and an objective structured clinical examination at the end of the module and 6 months later. Results were compared to data obtained from a historical control cohort (n = 70) unexposed to the intervention. Results: At the 6-month follow-up, scores in the knowledge test were significantly higher in the intervention than the control group (61.1% vs. 51.7%; p < .001). A similar pattern was observed in the objective structured clinical examination (71.5% vs. 60.5%; p < .001). More students in the intervention than control group agreed that smoking was a chronic disease (83.1% vs. 68.1%; p = .045). The control group was more likely to report recording smoking status (p = .018), but no group difference was detected regarding the report of advising to quit (p = .154). Conclusions: A novel teaching module for undergraduate medical students produced a sustained learning outcome in terms of knowledge, skills, and attitudes but not self-reported practice. Implications: Studies across the world have identified considerable knowledge gaps and deficits in practical training with regard to smoking cessation counseling in undergraduate medical students. This paper describes a teaching intervention informed by current recommendations for the design of educational activities aimed at enabling medical students to deliver adequate behavior change counseling. The teaching module was tailored to the needs of a specific healthcare system. Given its effectiveness as demonstrated in this prospective study, a rollout of this intervention in medical schools might have the potential to substantially improve medical students’ knowledge, skills, and attitudes in relation to smoking cessation counseling.

The actions of relaxin on the human cardiovascular system.
Sarwar, Mohsin; Du, Xiao-Jun; Dschietzig, Thomas B; Summers, Roger J
2017-05-01
The insulin-like peptide relaxin, originally identified as a hormone of pregnancy, is now known to exert a range of pleiotropic effects including vasodilatory, anti-fibrotic, angiogenic, anti-apoptotic and anti-inflammatory effects in both males and females. Relaxin produces these effects by binding to a cognate receptor RXFP1 and activating a variety of signalling pathways including cAMP, cGMP and MAPKs as well as by altering gene expression of TGF-β, MMPs, angiogenic growth factors and endothelin receptors. The peptide has been shown to be effective in halting or reversing many of the adverse effects including fibrosis in animal models of cardiovascular disease including ischaemia/reperfusion injury, myocardial infarction, hypertensive heart disease and cardiomyopathy. Relaxin given to humans is safe and produces favourable haemodynamic changes. Serelaxin, the recombinant form of relaxin, is now in extended phase III clinical trials for the treatment of acute heart failure. Previous clinical studies indicated that a 48 h infusion of relaxin improved 180 day mortality, yet the mechanism underlying this effect is not clear. This article provides an overview of the cellular mechanism of effects of relaxin and summarizes its beneficial actions in animal models and in the clinic. We also hypothesize potential mechanisms for the clinical efficacy of relaxin, identify current knowledge gaps and suggest new ways in which relaxin could be useful therapeutically. This article is part of a themed section on Recent Progress in the Understanding of Relaxin Family Peptides and their Receptors.

ImproveCareNow (ICN) is the largest pediatric learning health system in the nation and started as a quality improvement collaborative. To test the feasibility and validity of using ICN data for clinical research, we evaluated the effectiveness of anti-tumor necrosis factor-α (anti-TNFα) agents in the management of pediatric Crohn disease (CD). Data were collected in 35 pediatric gastroenterology practices (April 2007 to March 2012) and analyzed as a sequence of nonrandomized trials. Patients who had moderate to severe CD were classified as initiators or non-initiators of anti-TNFα therapy. Among 4130 patients who had pediatric CD, 603 were new users and 1211 were receiving anti-TNFα therapy on entry into ICN. During a 26-week follow-up period, rate ratios obtained from Cox proportional hazards models, adjusting for patient and disease characteristics and concurrent medications, were 1.53 (95% confidence interval [CI], 1.20-1.96) for clinical remission and 1.74 (95% CI, 1.33-2.29) for corticosteroid-free remission. The rate ratio for corticosteroid-free remission was comparable to the estimate produced by the adult SONIC study, which was a randomized controlled trial on the efficacy of anti-TNFα therapy. The number needed to treat was 5.2 (95% CI, 3.4-11.1) for clinical remission and 5.0 (95% CI, 3.4-10.0) for corticosteroid-free remission. In routine pediatric gastroenterology practice settings, anti-TNFα therapy was effective at achieving clinical and corticosteroid-free remission for patients who had Crohn disease. Using data from the ICN learning health system for the purpose of observational research is feasible and produces valuable new knowledge. Copyright © 2014 by the American Academy of Pediatrics.
Road Map For Diffusion Of Innovation In Health Care.
Balas, E Andrew; Chapman, Wendy W
2018-02-01
New scientific knowledge and innovation are often slow to disseminate. In other cases, providers rush into adopting what appears to be a clinically relevant innovation, based on a single clinical trial. In reality, adopting innovations without appropriate translation and repeated testing of practical application is problematic. In this article we provide examples of clinical innovations (for example, tight glucose control in critically ill patients) that were adopted inappropriately and that caused what we term a malfunction. To address the issue of malfunctions, we review various examples and suggest frameworks for the diffusion of knowledge leading to the adoption of useful innovations. The resulting model is termed an integrated road map for coordinating knowledge transformation and innovation adoption. We make recommendations for the targeted development of practice change procedures, practice change assessment, structured descriptions of tested interventions, intelligent knowledge management technologies, and policy support for knowledge transformation, including further standardization to facilitate sharing among institutions.
Diagnostic reasoning and underlying knowledge of students with preclinical patient contacts in PBL.
Diemers, Agnes D; van de Wiel, Margje W J; Scherpbier, Albert J J A; Baarveld, Frank; Dolmans, Diana H J M
2015-12-01
Medical experts have access to elaborate and integrated knowledge networks consisting of biomedical and clinical knowledge. These coherent knowledge networks enable them to generate more accurate diagnoses in a shorter time. However, students' knowledge networks are less organised and students have difficulties linking theory and practice and transferring acquired knowledge. Therefore we wanted to explore the development and transfer of knowledge of third-year preclinical students on a problem-based learning (PBL) course with real patient contacts. Before and after a 10-week PBL course with real patients, third-year medical students were asked to think out loud while diagnosing four types of paper patient problems (two course cases and two transfer cases), and explain the underlying pathophysiological mechanisms of the patient features. Diagnostic accuracy and time needed to think through the cases were measured. The think-aloud protocols were transcribed verbatim and different types of knowledge were coded and quantitatively analysed. The written pathophysiological explanations were translated into networks of concepts. Both the concepts and the links between concepts in students' networks were compared to model networks. Over the course diagnostic accuracy increased, case-processing time decreased, and students used less biomedical and clinical knowledge during diagnostic reasoning. The quality of the pathophysiological explanations increased: the students used more concepts, especially more model concepts, and they used fewer wrong concepts and links. The findings differed across course and transfer cases. The effects were generally less strong for transfer cases. Students' improved diagnostic accuracy and the improved quality of their knowledge networks suggest that integration of biomedical and clinical knowledge took place during a 10-week course. The differences between course and transfer cases demonstrate that transfer is complex and time-consuming. We therefore suggest offering students many varied patient contacts with the same underlying pathophysiological mechanism and encouraging students to link biomedical and clinical knowledge. © 2015 John Wiley & Sons Ltd.

Purpose: Intensity modulated radiation therapy (IMRT) is widely used to achieve a highly conformal dose and improve treatment outcome. However, plan quality and planning time are institute and planner dependent, and no standardized tool exists to recognize an optimal plan. RapidPlan, a knowledge-based algorithm, can generate constraints to assist optimization and produce high-quality IMRT plans. This report evaluated the quality and efficiency of using RapidPlan in nasopharyngeal carcinoma (NPC) IMRT planning. Methods and Materials: RapidPlan was configured using 79 radical IMRT plans for NPC; 20 consecutive NPC patients indicated for radical radiation therapy between October 2014 and May 2015 weremore » then recruited to assess its performance. The ability of RapidPlan to produce acceptable plans was evaluated. For plans that could not achieve clinical acceptance, manual touch-up was performed. The IMRT plans produced without RapidPlan (manual plans) and with RapidPlan (RP-2 plans, including those with manual touch-up) were compared in terms of dosimetric quality and planning efficiency. Results: RapidPlan by itself could produce clinically acceptable plans for 9 of the 20 patients; manual touch-up increased the number of acceptable plans (RP-2 plans) to 19. The target dose coverage and conformity were very similar. No difference was found in the maximum dose to the brainstem and optic chiasm. RP-2 plans delivered a higher maximum dose to the spinal cord (46.4 Gy vs 43.9 Gy, P=.002) but a lower dose to the parotid (mean dose to right parotid, 37.3 Gy vs 45.4 Gy; left, 34.4 Gy vs 43.1 Gy; P<.001) and the right cochlea (mean dose, 48.6 Gy vs 52.6 Gy; P=.02). The total planning time for RP-2 plans was significantly less than that for manual plans (64 minutes vs 295 minutes, P<.001). Conclusions: This study shows that RapidPlan can significantly improve planning efficiency and produce quality IMRT plans for NPC patients.« less

Adiponectin and Polycystic Ovary Syndrome
Groth, Susan W.
2013-01-01
Introduction Polycystic ovary syndrome (PCOS) has a prevalence of 5–8% in women of reproductive age. Women with PCOS have an increased risk of metabolic syndrome and associated comorbidities. Adiponectin is a circulating protein produced by adipocytes. Circulating levels of adiponectin are inversely related to adipocyte mass. Low levels occur with insulin resistance, type 2 diabetes, metabolic syndrome, and obesity-related cardiovascular disease. This article reviews the literature on the link between adiponectin and PCOS and the potential use of adiponectin as a biomarker for PCOS. Method Data-based studies on adiponectin and PCOS and adiponectin measurement were identified through the Medline (1950–2009) and ISI Web of Knowledge (1973–2009) databases. Results Fifteen studies related to adiponectin and PCOS met inclusion criteria and were included in this review. These studies present evidence that adiponectin is linked to insulin resistance, insulin sensitivity, body mass index (BMI), and adiposity. In women with PCOS, lower levels, as opposed to higher levels, of adiponectin occur in the absence of adiposity. Conclusion The relationships between adiponectin and insulin resistance and sensitivity, metabolic syndrome, and BMI in women with PCOS suggest that adiponectin potentially could serve as a marker for disease risk and provide opportunity for earlier intervention if knowledge is successfully translated from laboratory to clinical practice. However, further study of the relationship between adiponectin and PCOS is required before there can be direct application to clinical practice. PMID:20498127

A three-year, National Institutes of Health-funded residential project at a southeastern research university immersed 83 secondary science teachers in a summer institute called “Bench to Bedside.” Teachers were provided with knowledge, skills, experiences, and incentives to improve their science teaching and increase their awareness of scientific processes, technologies, and careers by examining the translational medicine continuum of basic to clinical research. This was done with the help of medical school researchers, clinical personnel, biotechnology entrepreneurs, program mentors, and prior year participants. A critical component of the institute was the preparation and implementation of an action research project that reflected teachers’ newly acquired knowledge and skills. Action research proposals were critiqued by project team members and feedback provided prior to action research implementation in schools during the following year. Teachers shared their action research with colleagues and project team at a symposium and online as a critical step in networking the teachers. Results of a mixed methods program evaluation strategy indicate that the program produced significant gains in teachers’ confidence to explain advanced biosciences topics, development of action research skills, and formation of a statewide biosciences network of key stakeholders. Constraints of time, variation in teacher content and action research background, technology availability, and school-related variables, among others, are discussed. PMID:29733086

This paper describes a qualitative program evaluation which sought to identify factors that either assist or impede the adoption of clinical evidence in everyday practice. Thirteen Australian projects were funded in a competitive grant program to adopt innovative strategies to improve the uptake of research evidence in everyday clinical practice. Project leaders' reports were analysed to collate common themes related to 1) critical elements in successful application of research knowledge, 2) barriers to implementing evidence, and 3) lessons for other organisations that might implement a similar project. Despite the diversity of the methods used to establish projects and the range of topics and clinical settings, many similarities were identified in the perceived critical success elements, barriers, and lessons for adopting clinical evidence. Eighteen themes emerged across the data including: leadership support; key stakeholder involvement; practice changes; communication; resources; education of staff; evaluation of outcomes; consumers; knowledge gaps; adoption/implementing staff; access to knowledge; risk assessment; collaboration; effectiveness of clinical research evidence; structure/organisation; cultural barriers; previous experiences; and information technology. Leaders of projects to adopt evidence in clinical practice identified barriers, critical success elements and lessons that impacted on their projects. A range of influences on the adoption of evidence were identified, and this knowledge can be used to assist others undertaking similar projects.

There is a paucity of formal clinician education concerning cancer survivorship care, which produces care barriers and poorer outcomes for survivors of childhood cancer. To address this, we implemented a curriculum in childhood cancer survivorship care for pediatric residents at the University of California, Los Angeles (UCLA). We examined the efficacy of this curriculum following program completion. A case-based curriculum was created and integrated within existing educational structures using Kern's model. We utilized the retrospective pre-posttest method to evaluate participating residents' knowledge, clinical skills, and attitudes towards cancer survivorship topics before and after receiving the curriculum. Pre-posttest items were compared using paired t tests and one-sided binomial tests. We analyzed free-response question items for major themes using constant comparative methods. Thirty-four residents completed the curriculum and its evaluation. Each assessment item significantly increased from pre- to post-curriculum; p < 0.05. Greater than 40% of residents improved in all but one assessment item post-curriculum; p < 0.05. Residents reported the curriculum enhanced their pediatric knowledge base (M = 3.24; SD = 0.65) and would recommend it to other residency programs; M = 3.24; SD = 0.69. Major themes included residents' request for additional oncofertility information, training in counseling survivors, and cancer survivorship training opportunities. A cancer survivorship curriculum can successfully increase trainees' knowledge, clinical skills, and comfort in discussing topics relevant to survivorship care. With increasing numbers of childhood cancer survivors living into adulthood, residents will likely treat this population regardless of intended career path. This curriculum represents one method to deliver formal cancer survivorship training.
Dissociating response systems: erasing fear from memory.
Soeter, Marieke; Kindt, Merel
2010-07-01
In addition to the extensive evidence in animals, we previously showed that disrupting reconsolidation by noradrenergic blockade produced amnesia for the original fear response in humans. Interestingly, the declarative memory for the fear association remained intact. These results asked for a solid replication. Moreover, given the constructive nature of memories, the intact recollection of the fear association could eventually 'rebuild' the fear memory, resulting in the spontaneous recovery of the fear response. Yet, perseverance of the amnesic effects would have substantial clinical implications, as even the most effective treatments for psychiatric disorders display high percentages of relapse. Using a differential fear conditioning procedure in humans, we replicated our previous findings by showing that administering propranolol (40mg) prior to memory reactivation eliminated the startle fear response 24h later. But most importantly, this effect persisted at one month follow-up. Notably, the propranolol manipulation not only left the declarative memory for the acquired contingency untouched, but also skin conductance discrimination. In addition, a close association between declarative knowledge and skin conductance responses was found. These findings are in line with the supposed double dissociation of fear conditioning and declarative knowledge relative to the amygdala and hippocampus in humans. They support the view that skin conductance conditioning primarily reflects contingency learning, whereas the startle response is a rather specific measure of fear. Furthermore, the results indicate the absence of a causal link between the actual knowledge of a fear association and its fear response, even though they often operate in parallel. Interventions targeting the amygdalar fear memory may be essential in specifically and persistently dampening the emotional impact of fear. From a clinical and ethical perspective, disrupting reconsolidation points to promising interventions persistently erasing fear responses from trauma memory without affecting the actual recollection.
Rational decision-making in mental health: the role of systematic reviews.
Gilbody, Simon M.; Petticrew, Mark
1999-09-01
BACKGROUND: "Systematic reviews" have come to be recognized as the most rigorous method of summarizing confusing and often contradictory primary research in a transparent and reproducible manner. Their greatest impact has been in the summarization of epidemiological literature - particularly that relating to clinical effectiveness. Systematic reviews also have a potential to inform rational decision-making in healthcare policy and to form a component of economic evaluation. AIMS OF THE STUDY: This article aims to introduce the rationale behind systematic reviews and, using examples from mental health, to introduce the strengths and limitations of systematic reviews, particularly in informing mental health policy and economic evaluation. METHODS: Examples are selected from recent controversies surrounding the introduction of new psychiatric drugs (anti-depressants and anti-schizophrenia drugs) and methods of delivering psychiatric care in the community (case management and assertive community treatment). The potential for systematic reviews to (i) produce best estimates of clinical efficacy and effectiveness, (ii) aid economic evaluation and policy decision-making and (iii) highlight gaps in the primary research knowledge base are discussed. Lastly examples are selected from outside mental health to show how systematic reviews have a potential to be explicitly used in economic and health policy evaluation. RESULTS: Systematic reviews produce the best estimates of clinical efficacy, which can form an important component of economic evaluation. Importantly, serious methodological flaws and areas of uncertainty in the primary research literature are identified within an explicit framework. Summary indices of clinical effectiveness can be produced, but it is difficult to produce such summary indices of cost effectiveness by pooling economic data from primary studies. Modelling is commonly used in economic and policy evaluation. Here, systematic reviews can provide the best estimates of effectiveness and, importantly, highlight areas of uncertainty that can be used in "sensitivity analysis". DISCUSSION: Systematic reviews are an important recent methodological advance, the potential for which has only begun to be realized in mental health. This use of systematic reviews is probably most advanced in producing critical summaries of clinical effectiveness data. Systematic reviews cannot produce valid and believable conclusions when the primary research literature is of poor quality. An important function of systematic reviews will be in highlighting this poor quality research which is of little use in mental health decision making. IMPLICATIONS FOR HEALTH PROVISION: Health care provision should be both clinically and cost effective. Systematic reviews are a key component in ensuring that this goal is achieved. IMPLICATIONS FOR HEALTH POLICIES: Systematic reviews have potential to inform health policy. Examples presented show that health policy is often made without due consideration of the research evidence. Systematic reviews can provide robust and believable answers, which can help inform rational decision-making. Importantly, systematic reviews can highlight the need for important primary research and can inform the design of this research such that it provides answers that will help in forming healthcare policy. IMPLICATIONS FOR FURTHER RESEARCH: Systematic reviews should precede costly (and often unnecessary) primary research. Many areas of health policy and practice have yet to be evaluated using systematic review methodology. Methods for the summarization of economic data are methodologically complex and deserve further research

Background Cosmetics can affect the skin condition profoundly, and yet no survey has been performed in Koreans visiting dermatology clinics. Objective To assess knowledge and consumer behavior regarding cosmetics in Koreans visiting dermatology clinics. Methods A questionnaire consisting of 43 questions concerning demographics and use/knowledge/selection/purchase of cosmetics was given to patients and accompanying persons who visited dermatologic clinics in university and private clinic settings. Results In total 1,015 subjects (73.2% females, mean age 32.5 years) completed the survey. Education level was college or higher in 72.8%. Thirty-one percent had been diagnosed with a skin disorder, atopic dermatitis and seborrheic dermatitis being the most frequent diagnoses (33.7% and 16.8%, respectively). The frequency of makeup/sunscreen/functional cosmetics use, amount of sunscreen use, recognition of functional cosmetics, and knowledge of shelf life were significantly correlated with level of education. Among “functional cosmetics,” whitening products were used most frequently (29.2%). Regardless of education level, 79.2% purchased cosmetics without checking ingredients, and 85.7% were unaware of the all-ingredient-labelling regulations, and yet subjects considered ingredient the most important factor when purchasing a product. Conclusion Outpatient subjects in their twenties and thirties are the most knowledgeable about cosmetics in Korea. PMID:28392645

To better understand the literature searching preferences of clinical providers we conducted an institution-wide survey assessing the most preferred knowledge searching techniques. A survey regarding literature searching preferences was sent to 1862 unique clinical providers throughout Mayo Clinic. The survey consisted of 25 items asking respondents to select which clinical scenarios most often prompt literature searches as well as identify their most preferred knowledge resources. A total of 450 completed surveys were returned and analyzed (24% response rate). 48% of respondents perform literature searches for more than half of their patient interactions with 91% of all searches occurring either before or within 3 hours of the patient interaction. When a search is performed 57% of respondents prefer synthesized information sources as compared to only 13% who prefer original research. 82% of knowledge searches are performed on a workstation or office computer while just 10% occur on a mobile device or at home. Providers in our survey demonstrate a need to answer clinical questions on a regular basis, especially in the diagnosis and therapy domains. Responses suggest that most of these searches occur using synthesized knowledge sources in the patient care setting within a very short time from the patient interaction.
Closing the gap between knowledge and clinical application: challenges for genomic translation.
Burke, Wylie; Korngiebel, Diane M
2015-01-01
Despite early predictions and rapid progress in research, the introduction of personal genomics into clinical practice has been slow. Several factors contribute to this translational gap between knowledge and clinical application. The evidence available to support genetic test use is often limited, and implementation of new testing programs can be challenging. In addition, the heterogeneity of genomic risk information points to the need for strategies to select and deliver the information most appropriate for particular clinical needs. Accomplishing these tasks also requires recognition that some expectations for personal genomics are unrealistic, notably expectations concerning the clinical utility of genomic risk assessment for common complex diseases. Efforts are needed to improve the body of evidence addressing clinical outcomes for genomics, apply implementation science to personal genomics, and develop realistic goals for genomic risk assessment. In addition, translational research should emphasize the broader benefits of genomic knowledge, including applications of genomic research that provide clinical benefit outside the context of personal genomic risk.

Widespread cooperation between domain experts and front-line clinicians is a key component of any successful clinical knowledge management framework. Peer review is an established form of cooperation that promotes the dissemination of new knowledge. The authors describe three peer collaboration scenarios that have been implemented using the knowledge management infrastructure available at Intermountain Healthcare. Utilization results illustrating the early adoption patterns of the proposed scenarios are presented and discussed, along with succinct descriptions of planned enhancements and future implementation efforts.

What is psychiatry? Co-producing complexity in mental health
Pickersgill, Martyn
2012-01-01
What is psychiatry? Such a question is increasingly important to engage with in light of the development of new diagnostic frameworks that have wide-ranging and international clinical and societal implications. I suggest in this reflective essay that ‘psychiatry' is not a singular entity that enjoins consistent forms of critique along familiar axes; rather, it is a heterogeneous assemblage of interacting material and symbolic elements (some of which endure, and some of which are subject to innovation). In underscoring the diversity of psychiatry, I seek to move towards further sociological purchase on what remains a contested and influential set of discourses and practices. This approach foregrounds the relationships between scientific knowledge, biomedical institutions, social action and subjective experience; these articulations co-produce both psychiatry and each other. One corollary of this emphasis on multiplicity and incoherence within psychiatric theory, research and practice, is that critiques which elide this complexity are rendered problematic. Engagements with psychiatry are, I argue, best furthered by recognising its multifaceted nature. PMID:23226975
The socio-organizational age of artificial intelligence in medicine.
Stefanelli, M
2001-08-01
The increasing pressure on Health Care Organizations (HCOs) to ensure efficiency and cost-effectiveness, balancing quality of care and cost containment, will drive them towards a more effective management of medical knowledge derived from research findings. The relation between science and health services has until recently been too casual. The primary job of medical research has been to understand the mechanisms of disease and produce new treatments, not to worry about the effectiveness of the new treatments or their implementation. As a result many new treatments have taken years to become part of routine practice, ineffective treatments have been widely used, and medicine has been opinion rather than evidence based. This results in suboptimal care for patients. Knowledge management technology may provide effective approaches in speeding up the diffusion of innovative medical procedures whose clinical effectiveness have been proved: the most interesting one is represented by computer-based utilization of evidence-based clinical guidelines. As researchers in Artificial Intelligence in Medicine (AIM), we are committed to foster the strategic transition from opinion to evidence-based decision making. Reviews of the effectiveness of various methods of guideline dissemination show that the most predictable impact is achieved when the guideline is made accessible through computer-based and patient specific reminders that are integrated into the clinician's workflow. However, the traditional single doctor-patient relationship is being replaced by one in which the patient is managed by a team of health care professionals, each specializing in one aspect of care. Such shared care depends critically on the ability to share patient-specific information and medical knowledge easily among them. Strategically there is a need to take a more clinical process view of health care delivery and to identify the appropriate organizational and information infrastructures to support this process. Thus, the great challenge for AIM researchers is to exploit the astonishing capabilities of new technologies to disseminate their tools to benefit HCOs by assuring the conditions of knowledge management and organizational learning at the fullest extent possible. To achieve such a strategic goal, a guideline can be viewed as a model of the care process. It must be combined with an organization model of the specific HCO to build patient careflow management systems. Artificial intelligence can be extensively used to design innovative tools to support all the development stages of those systems. However, exploiting the knowledge represented in a guideline to build them requires to extend today's workflow technology by solving some challenging problems.
Knowledge bases, clinical decision support systems, and rapid learning in oncology.
Yu, Peter Paul
2015-03-01
One of the most important benefits of health information technology is to assist the cognitive process of the human mind in the face of vast amounts of health data, limited time for decision making, and the complexity of the patient with cancer. Clinical decision support tools are frequently cited as a technologic solution to this problem, but to date useful clinical decision support systems (CDSS) have been limited in utility and implementation. This article describes three unique sources of health data that underlie fundamentally different types of knowledge bases which feed into CDSS. CDSS themselves comprise a variety of models which are discussed. The relationship of knowledge bases and CDSS to rapid learning health systems design is critical as CDSS are essential drivers of rapid learning in clinical care.

To move beyond a select few genes/drugs, the successful adoption of pharmacogenomics into routine clinical care requires a curated and machine-readable database of pharmacogenomic knowledge suitable for use in an electronic health record (EHR) with clinical decision support (CDS). Recognizing that EHR vendors do not yet provide a standard set of CDS functions for pharmacogenetics, the Clinical Pharmacogenetics Implementation Consortium (CPIC) Informatics Working Group is developing and systematically incorporating a set of EHR-agnostic implementation resources into all CPIC guidelines. These resources illustrate how to integrate pharmacogenomic test results in clinical information systems with CDS to facilitate the use of patient genomic data at the point of care. Based on our collective experience creating existing CPIC resources and implementing pharmacogenomics at our practice sites, we outline principles to define the key features of future knowledge bases and discuss the importance of these knowledge resources for pharmacogenomics and ultimately precision medicine. © The Author 2016.

One antidote to moral distress is stronger moral agency-that is, an enhanced ability to act to bring about change. The Clinical Ethics Residency for Nurses, an educational program developed and run in two large northeastern academic medical centers with funding from the Health Resources and Services Administration, intended to strengthen nurses' moral agency. Drawing on Improving Competencies in Clinical Ethics Consultation: An Education Guide, by the American Society for Bioethics and Humanities, and on the goals of the nursing profession, CERN sought to change attitudes, increase knowledge, and develop skills to act on one's knowledge. One of the key insights the faculty members brought to the design of this program is that knowledge of clinical ethics is not enough to develop moral agency. In addition to lecture-style classes, CERN employed a variety of methods based in adult learning theory, such as active application of ethics knowledge to patient scenarios in classroom discussion, simulation, and the clinical practicum. Overwhelmingly, the feedback from the participants (sixty-seven over three years of the program) indicated that CERN achieved transformative learning. © 2014 by The Hastings Center.

To review Bayesian methodology and its utility to clinical decision making and research in the critical care field. Clinical, epidemiological, and biostatistical studies on Bayesian methods in PubMed and Embase from their inception to December 2013. Bayesian methods have been extensively used by a wide range of scientific fields, including astronomy, engineering, chemistry, genetics, physics, geology, paleontology, climatology, cryptography, linguistics, ecology, and computational sciences. The application of medical knowledge in clinical research is analogous to the application of medical knowledge in clinical practice. Bedside physicians have to make most diagnostic and treatment decisions on critically ill patients every day without clear-cut evidence-based medicine (more subjective than objective evidence). Similarly, clinical researchers have to make most decisions about trial design with limited available data. Bayesian methodology allows both subjective and objective aspects of knowledge to be formally measured and transparently incorporated into the design, execution, and interpretation of clinical trials. In addition, various degrees of knowledge and several hypotheses can be tested at the same time in a single clinical trial without the risk of multiplicity. Notably, the Bayesian technology is naturally suited for the interpretation of clinical trial findings for the individualized care of critically ill patients and for the optimization of public health policies. We propose that the application of the versatile Bayesian methodology in conjunction with the conventional statistical methods is not only ripe for actual use in critical care clinical research but it is also a necessary step to maximize the performance of clinical trials and its translation to the practice of critical care medicine.

This study evaluated second-, third-, and fourth-year dental students' ability to identify systemic conditions associated with periodontal disease, risk factors most important for referral, and medications with an effect on the periodontium and their ability to apply this knowledge to make clinical decisions regarding treatment and referral of periodontal patients. A twenty-one question survey was administered at one U.S. dental school in the spring semester of 2012 to elicit the students' knowledge and confidence regarding clinical reasoning. The response rate was 86 percent. Periodontal risk factors were accurately selected by at least 50 percent of students in all three classes; these were poorly controlled diabetes, ≥6 mm pockets posteriorly, and lack of response to previous non-surgical therapy. Confidence in knowledge, knowledge of risk factors, and knowledge of medications with an effect on the periodontium improved with training and were predictive of better referral decision making. The greatest impact of training was seen on the students' ability to make correct decisions about referral and treatment for seven clinical scenarios. Although the study found a large increase in the students' abilities from the second through fourth years, the mean of 4.6 (out of 7) for the fourth-year students shows that, on average, those students missed correct treatment or referral on more than two of seven clinical cases. These results suggest that dental curricula should emphasize more critical decision making with respect to referral and treatment criteria in managing the periodontal patient.
Power and promise of narrative for advancing physical therapist education and practice.

This perspective article provides a justification for and an overview of the use of narrative as a pedagogical tool for educators to help physical therapist students, residents, and clinicians develop skills of reflection and reflexivity in clinical practice. The use of narratives is a pedagogical approach that provides a reflective and interpretive framework for analyzing and making sense of texts, stories, and other experiences within learning environments. This article describes reflection as a well-established method to support critical analysis of clinical experiences; to assist in uncovering different perspectives of patients, families, and health care professionals involved in patient care; and to broaden the epistemological basis (ie, sources of knowledge) for clinical practice. The article begins by examining how phronetic (ie, practical and contextual) knowledge and ethical knowledge are used in physical therapy to contribute to evidence-based practice. Narrative is explored as a source of phronetic and ethical knowledge that is complementary but irreducible to traditional objective and empirical knowledge-the type of clinical knowledge that forms the basis of scientific training. The central premise is that writing narratives is a cognitive skill that should be learned and practiced to develop critical reflection for expert practice. The article weaves theory with practical application and strategies to foster narrative in education and practice. The final section of the article describes the authors' experiences with examples of integrating the tools of narrative into an educational program, into physical therapist residency programs, and into a clinical practice. © 2015 American Physical Therapy Association.

Governing sex workers in Timor Leste.
Harrington, Carol
2011-01-01
This paper argues that international security forces in Timor Leste depend upon civilian partners in HIV/AIDs "knowledge networks" to monitor prostitutes' disease status. These networks produce mobile expertise, techniques of government and forms of personhood that facilitate international government of distant populations without overt coercion. HIV/AIDs experts promote techniques of peer education, empowerment and community mobilisation to construct women who sell sex as health conscious sex workers. Such techniques make impoverished women responsible for their disease status, obscuring the political and economic contexts that produced that status. In the militarised context of Timor Leste, knowledge of the sexual conduct of sub-populations labelled high risk circulates among global HIV/AIDs knowledge networks, confirming their expert status while obscuring the sexual harm produced by military intervention. HIV/AIDs knowledge networks have recently begun to build Timorese sex worker organisations by contracting an Australian sex worker NGO to train a Timorese NGO tasked with building sex worker identity and community. Such efforts fail to address the needs and priorities of the women supposedly empowered. The paper engages theories of global knowledge networks, mobile technologies of government, and governmentality to analyse policy documents, reports, programmes, official statements, speeches, and journalistic accounts regarding prostitution in Timor Leste.

Curricula changes in physical therapist education programs in Canada emphasize evidence-based practice skills, including literature retrieval and evaluation. Do graduates use these skills in practice? The aim of this study was to evaluate the use of research information in the clinical decision making of therapists with different years of experience and evidence-based practice preparation. Perceptions about evidence-based practice were explored qualitatively. A cross-sectional study with 4 graduating cohorts was conducted. Eighty physical therapists representing 4 different graduating cohorts participated in interviews focused on 2 clinical scenarios. Participants had varying years of clinical experience (range=1-15 years) and academic knowledge of evidence-based practice skills. Therapists discussed the effectiveness of interventions related to the scenarios and identified the sources of information used to reach decisions. Participants also answered general questions related to evidence-based practice knowledge. Recent graduates demonstrated better knowledge of evidence-based practice skills compared with therapists with 6 to 15 years of clinical experience. However, all groups used clinical experience most frequently as their source of information for clinical decisions. Research evidence was infrequently included in decision making. This study used a convenience sample of therapists who agreed to volunteer for the study. The results suggest a knowledge-to-practice gap; graduates are not using the new skills to inform their practice. Tailoring academic evidence-based activities more to the time constraints of clinical practice may help students to be more successful in applying evidence in practice. Academic programs need to do more to create and nurture environments in both academic and clinical settings to ensure students practice using evidence-based practice skills across settings. © 2015 American Physical Therapy Association.

The purpose of this article is to discuss the role of the adult-gerontology clinical nurse specialist in addressing the problem of delirium in hospitalized older adults through strategies to improve nurse knowledge. Delirium is a significant issue in hospitalized older adults. This acute confusional state can adversely impact older adults in various ways. Delirium has been implicated in (1) poor physical, cognitive, and psychological outcomes, (2) prolonged hospitalizations, (3) increased costs of care, (4) need for continued postacute care, and (5) patient and provider stress. To prevent delirium, nurses must possess the knowledge to identify risk factors and institute preventive strategies. Once a change in mental status occurs, it is critical that nurses recognize delirium and the steps necessary to provide safe, effective care. Nurses are the major providers of bedside care; however, multiple studies have identified a lack of nurse knowledge regarding delirium. The adult-gerontology clinical nurse specialist can be instrumental in fostering knowledge on this important issue. Multiple interventions can be conducted by the adult-gerontology clinical nurse specialist with acute care nurses to increase delirium knowledge. A review of the literature revealed strategies that might be used in the hospital setting. Before educational endeavors, it is crucial to assess baseline nurse knowledge of delirium. Educational strategies can then include use of standardized delirium assessment tools, implementation of the Geriatric Resource Nurse model, fostering geriatric case studies and simulations, conducting geriatric grand rounds, and development of structured delirium educational programs. Exploring the patient experience, post delirium, can provide an invaluable, first-hand account of the acute confusional state. This information can impact nurse knowledge as well as patient safety and well-being. Geriatric certification and professional organizational involvement can be encouraged. Numerous online geriatric resources can be shared with nurses to enhance knowledge of delirium. Improved nurse knowledge will assist in preventing/decreasing incidents of delirium and thwart the negative outcomes associated with delirium occurrence in hospitalized older adults. Nurse knowledge can be measured and patient care assessed to determine the effectiveness of the proposed educational strategies. The goal of the identified adult-gerontology clinical nurse specialist-led educational initiatives is to improve knowledge of delirium, which will assist nurses in providing evidence-based, safe, appropriate care to all hospitalized older adults.
Scotland's Knowledge Network: translating knowledge into action to improve quality of care.
Wales, A; Graham, S; Rooney, K; Crawford, A

The Knowledge Network (www.knowledge.scot.nhs.uk) is Scotland's online knowledge service for health and social care. It is designed to support practitioners to apply knowledge in frontline delivery of care, helping to translate knowledge into better health-care outcomes through safe, effective, person-centred care. The Knowledge Network helps to combine the worlds of evidence-based practice and quality improvement by providing access to knowledge about the effectiveness of clinical interventions ('know-what') and knowledge about how to implement this knowledge to support individual patients in working health-care environments ('know-how'). An 'evidence and guidance' search enables clinicians to quickly access quality-assured evidence and best practice, while point of care and mobile solutions provide knowledge in actionable formats to embed in clinical workflow. This research-based knowledge is complemented by social networking services and improvement tools which support the capture and exchange of knowledge from experience, facilitating practice change and systems improvement. In these cases, the Knowledge Network supports key components of the knowledge-to-action cycle--acquiring, creating, sharing and disseminating knowledge to improve performance and innovate. It provides a vehicle for implementing the recommendations of the national Knowledge into Action review, which outlines a new national approach to embedding knowledge in frontline practice and systems improvement.

The goal of the CDS Consortium (CDSC) is to assess, define, demonstrate, and evaluate best practices for knowledge management and clinical decision support in healthcare information technology at scale - across multiple ambulatory care settings and Electronic Health Record technology platforms. In the course of the CDSC research effort, it became evident that a sound legal foundation was required for knowledge sharing and clinical decision support services in order to address data sharing, intellectual property, accountability, and liability concerns. This paper outlines the framework utilized for developing agreements in support of sharing, accessing, and publishing content via the CDSC Knowledge Management Portal as well as an agreement in support of deployment and consumption of CDSC developed web services in the context of a research project under IRB oversight.
Ontology-based reusable clinical document template production system.

Clinical documents embody professional clinical knowledge. This paper shows an effective clinical document template (CDT) production system that uses a clinical description entity (CDE) model, a CDE ontology, and a knowledge management system called STEP that manages ontology-based clinical description entities. The ontology represents CDEs and their inter-relations, and the STEP system stores and manages CDE ontology-based information regarding CDTs. The system also provides Web Services interfaces for search and reasoning over clinical entities. The system was populated with entities and relations extracted from 35 CDTs that were used in admission, discharge, and progress reports, as well as those used in nursing and operation functions. A clinical document template editor is shown that uses STEP.

Previously published evidence has established major clinical benefits from using computer-aided design, computer-aided manufacturing, and additive manufacturing to produce patient-specific devices. These include cutting guides, drilling guides, positioning guides, and implants. However, custom devices produced using these methods are still not in routine use, particularly by the UK National Health Service. Oft-cited reasons for this slow uptake include the following: a higher up-front cost than conventionally fabricated devices, material-choice uncertainty, and a lack of long-term follow-up due to their relatively recent introduction. This article identifies a further gap in current knowledge - that of design rules, or key specification considerations for complex computer-aided design/computer-aided manufacturing/additive manufacturing devices. This research begins to address the gap by combining a detailed review of the literature with first-hand experience of interdisciplinary collaboration on five craniofacial patient case studies. In each patient case, bony lesions in the orbito-temporal region were segmented, excised, and reconstructed in the virtual environment. Three cases translated these digital plans into theatre via polymer surgical guides. Four cases utilised additive manufacturing to fabricate titanium implants. One implant was machined from polyether ether ketone. From the literature, articles with relevant abstracts were analysed to extract design considerations. In all, 19 frequently recurring design considerations were extracted from previous publications. Nine new design considerations were extracted from the case studies - on the basis of subjective clinical evaluation. These were synthesised to produce a design considerations framework to assist clinicians with prescribing and design engineers with modelling. Promising avenues for further research are proposed.
A New Clinical Pain Knowledge Test for Nurses: Development and Psychometric Evaluation.
Bernhofer, Esther I; St Marie, Barbara; Bena, James F
2017-08-01
All nurses care for patients with pain, and pain management knowledge and attitude surveys for nurses have been around since 1987. However, no validated knowledge test exists to measure postlicensure clinicians' knowledge of the core competencies of pain management in current complex patient populations. To develop and test the psychometric properties of an instrument designed to measure pain management knowledge of postlicensure nurses. Psychometric instrument validation. Four large Midwestern U.S. hospitals. Registered nurses employed full time and part time August 2015 to April 2016, aged M = 43.25 years; time as RN, M = 16.13 years. Prospective survey design using e-mail to invite nurses to take an electronic multiple choice pain knowledge test. Content validity of initial 36-item test "very good" (95.1% agreement). Completed tests that met analysis criteria, N = 747. Mean initial test score, 69.4% correct (range 27.8-97.2). After revision/removal of 13 unacceptable questions, mean test score was 50.4% correct (range 8.7-82.6). Initial test item percent difficulty range was 15.2%-98.1%; discrimination values range, 0.03-0.50; final test item percent difficulty range, 17.6%-91.1%, discrimination values range, -0.04 to 1.04. Split-half reliability final test was 0.66. A high decision consistency reliability was identified, with test cut-score of 75%. The final 23-item Clinical Pain Knowledge Test has acceptable discrimination, difficulty, decision consistency, reliability, and validity in the general clinical inpatient nurse population. This instrument will be useful in assessing pain management knowledge of clinical nurses to determine gaps in education, evaluate knowledge after pain management education, and measure research outcomes.

To assess the impact of an elective clinical research course on second- and third-year pharmacy students' knowledge of clinical research methods, training programs, career options, and interest in pursuing postgraduate training. A 2-credit hour elective course in clinical research was designed that included lectures, discussions, workshops, and in-class presentations related to study design and implementation, protocol synthesis, research evaluation, ethical and legal considerations, data analysis, and professional opportunities involving clinical research. Learner knowledge of these topics was assessed using several methods, including 3 assignments related to research protocol, ethical documentation, and presentation. A survey instrument designed to evaluate the effect the course had on pharmacy students' knowledge of clinical research methods and interest in pursuing postgraduate training in clinical research was administered. Students who completed the elective had a greater level of familiarity with research-related topics, training options, and career opportunities (p < 0.05) and a greater interest in pursuing a career in clinical research (p < 0.05) than did students in a matched control group. Taking a 2-credit hour elective course in clinical research increased pharmacy students' interest in pursuing a career in clinical research.

Knowledge-related barriers to safely implement early rehabilitation programs in intensive care units (ICUs) may be overcome via targeted education. The purpose of this study was to evaluate the effectiveness of an interactive educational session on short-term knowledge of clinical decision-making for safe rehabilitation of patients in ICUs. A case-based teaching approach, drawing from published safety recommendations for initiation of rehabilitation in ICUs, was used with a multidisciplinary audience. An audience response system was incorporated to promote interaction and evaluate knowledge before vs. after the educational session. Up to 175 audience members, of 271 in attendance (129 (48%) physical therapists, 51 (19%) occupational therapists, 31 (11%) nursing, 14 (5%) physician, 46 (17%) other), completed both the pre- and post-test questions for each of the six unique patient cases. In four of six patient cases, there was a significant (p< 0.001) increase in identifying the correct answer regarding initiation of rehabilitation activities. This learning effect was similar irrespective of participants' years of experience and clinical discipline. An interactive, case-based, educational session may be effective for increasing short-term knowledge, and identifying knowledge gaps, regarding clinical decision-making for safe rehabilitation of patients in ICUs. Implications for Rehabilitation Lack of knowledge regarding the safety considerations for early rehabilitation of ICU patients is a barrier to implementing early rehabilitation. Interactive educational formats, such as the use of audience response systems, offer a new method of teaching and instantly assessing learning of clinically important information. In a small study, we have shown that an interactive, case-based educational format may be used to effectively teach clinical decision-making for the safe rehabilitation of ICU patients to a diverse audience of clinicians.

Our objective was to evaluate the effectiveness of hands-on training at a bedside ultrasound (US) symposium ("Ultrafest") to improve both clinical knowledge and image acquisition skills of medical students. Primary outcome measure was improvement in multiple choice questions on pulmonary or Focused Assessment with Sonography in Trauma (FAST) US knowledge. Secondary outcome was improvement in image acquisition for either pulmonary or FAST. Prospective cohort study of 48 volunteers at "Ultrafest," a free symposium where students received five contact training hours. Students were evaluated before and after training for proficiency in either pulmonary US or FAST. Proficiency was assessed by clinical knowledge through written multiple-choice exam, and clinical skills through accuracy of image acquisition. We used paired sample t-tests with students as their own controls. Pulmonary knowledge scores increased by a mean of 10.1 points (95% CI [8.9-11.3], p<0.00005), from 8.4 to a posttest average of 18.5/21 possible points. The FAST knowledge scores increased by a mean of 7.5 points (95% CI [6.3-8.7] p<0.00005), from 8.1 to a posttest average of 15.6/21. We analyzed clinical skills data on 32 students. The mean score was 1.7 pretest and 4.7 posttest of 12 possible points. Mean improvement was 3.0 points (p<0.00005) overall, 3.3 (p=0.0001) for FAST, and 2.6 (p=0.003) for the pulmonary US exam. This study suggests that a symposium on US can improve clinical knowledge, but is limited in achieving image acquisition for pulmonary and FAST US assessments. US training external to official medical school curriculum may augment students' education.
Is the decline of human anatomy hazardous to medical education/profession?--A review.
Singh, Rajani; Shane Tubbs, R; Gupta, Kavita; Singh, Man; Jones, D Gareth; Kumar, Raj
2015-12-01
The continuous decrease in teaching time, the artificially created scarcity of competent anatomical faculties and a reduced allocation of resources have brought about the decline of anatomy in medical education. As a result of this, anatomical knowledge and the standard of medical education have fallen with consequences including safety in clinical practice. The aim of the present study is to analyze this declining phase of anatomy and its impact on medical education and to consider corrective measures. This article expresses comparative viewpoints based on a review of the literature. Anatomy enables doctors to master the language of medical science so they can communicate with patients, the public and fellow doctors and diagnose and treat diseases successfully in all medical fields. No medical specialist or expert can master their field without adequate knowledge of human anatomy. The shrinkage of anatomical schedules, inadequate faculties and declining allocation of resources is therefore unfortunate. These factors produce stress in both student and faculty creating gaps in anatomical knowledge that means insufficient skill is developed to practice medicine safely. This decline is hazardous not only to the medical profession but also to society. Reforms consisting of balanced rescheduling of medical curricula and optimum resource allocation have been proposed to improve the standard of education of doctors.

To evaluate the impact of traditional counseling and patient-centered counseling, either alone or with recorded audio counseling reinforcement, on glaucoma knowledge and clinical follow-up. Prospective randomized controlled trial. Newly diagnosed adult glaucoma patients were randomized to 1 of 3 categories of glaucoma counseling: traditional counseling, patient-centered counseling, or patient-centered counseling with audio counseling reinforcement. Demographic and clinical information from each subject was ascertained, and all subjects completed the Glaucoma Knowledge Assessment before and after counseling sessions at the time of diagnosis and at 1-month follow-up. Patients were instructed to return to clinic for routine follow-up at 1, 3, 6, 9, and 12 months after enrollment. A multivariate logistic regression model was used to determine factors associated with appropriate clinical follow-up. Overall, only 13.5% of subjects had appropriate clinical follow-up at 1 year, defined as attending at least 3 follow-up visits during that interval, and there was no significant difference between counseling groups. The mean glaucoma knowledge assessment score (GKAS) improved by 77.6% with the initial counseling intervention (P < .0001), decreased by 17.4% within a 1-month period following initial counseling, and improved by 22.8% (P < .001) after the second counseling intervention. Monthly household income over 2500 rupees, GKAS greater than 5 after initial counseling, and undergoing any ocular surgical procedure were all independent predictors of appropriate follow-up. While all 3 counseling methods resulted in transient improvement of patient knowledge regarding glaucomatous disease, follow-up rates were poor for all groups. Poor retention of glaucoma knowledge may impact the likelihood of patient follow-up, and reinforcement with repeated counseling may be beneficial with regard to both disease knowledge and follow-up.

Poor enrollment plagues most clinical trials. Furthermore, despite mandates to improve minority representation in clinical trial participation, little progress has been made. We investigated the knowledge and attitudes of adolescents related to clinical trials and made race/ethnicity comparisons in an attempt to identify a possible educational intervention target. Students aged 13-18 years in southeast Michigan were offered participation through a class at one high school or two academic summer enrichment programs that drew from multiple high schools (73% response). Questionnaires previously validated in adults were administered. Non-Hispanic whites were compared with minorities using Wilcoxon rank-sum tests. Of the 82 respondents, the median age was 16 years (interquartile range: 15-17 years); 22 (28%) were white, 41 (51%) were African American, 11 (14%) were multiracial, 2 (2%) were American Indian or Alaska Native, 1 (1%) was Asian, 3 (4%) were Native Hawaiian or other Pacific Islander, and 2 respondents did not report a race (but did report Hispanic ethnicity). Nine (12%) were Hispanic. Only 27 (33%) had ever heard of a clinical trial. On a scale from 1 (most receptive) to 5 (least receptive) for learning more about a clinical trial for a relevant medical condition, the median score was 2 (interquartile range: 1-3) and for participating in a clinical trial for a relevant medical condition was 2 (interquartile range: 2-3). Overall knowledge was poor, with a median of 46% (interquartile range: 23%-62%) of knowledge answers correct. Knowledge was reduced (p = 0.0006) and attitudes were more negative (p = 0.05) in minorities than non-Hispanic whites, while minorities also endorsed more substantial barriers to trial participation (p = 0.0002). Distrust was similar between minority students and non-Hispanic whites (p = 0.15), and self-efficacy was greater in non-Hispanic whites (p = 0.05). Educational interventions directed toward adolescents that address knowledge, attitudes, and distrust in order to improve clinical trial awareness and receptivity overall are needed and may represent a tool to address disparities in minority enrollment in clinical trials. © The Author(s) 2015.

Background Nurses as the members of health care professionals need to improve their knowledge and competencies particularly in diabetes mellitus through continuing nursing education programs. E-learning is an indirect method of training that can meet nurses’ educational needs. This study is aimed at validating a web-based diabetes education program through measurement of nurses’ knowledge and clinical competency in diabetes and nurses’ perception about its usability and quality. Methods This Quasi-experimental research was conducted on a single group of 31 nurses employed in hospitals affiliated with Shiraz University of Medical Sciences. We used a 125 MCQ knowledge test and Objective Structured Clinical Exam (OSCE) to measure knowledge and clinical competency of nurses in diabetes before and after intervention. A Learning Management System (LMS) was designed to provide educational content in the form of 12 multimedia electronic modules, interactive tests; a forum and learning activities. Nurses were trained for two months in this system after which the post-test was administered. Each nurse completed two questionnaires for measurement of their perceptions on usability and quality. We used descriptive statistics for demographic and descriptive data analysis. Paired t-test was used to compare pre- and post-data using SPSS. Results The findings showed significant differences in knowledge scores (p < 0.001), total score of clinical competencies (p < 0.001), and all ten assessed clinical competencies. The range of ratings given by participants varied on the six usability variables of Web-based training (2.96-4.23 from 5) and eight quality variables of Web-based training (3.58-4.37 from 5). Conclusion Web-based education increased nurses’ knowledge and competencies in diabetes. They positively evaluated Web-based learning usability and quality. It is hoped that this course will have a positive clinical outcomes. PMID:26086025

A Learning Management System (LMS) was designed to provide educational content in the form of 12 multimedia electronic modules, interactive tests; a forum and learning activities. Nurses were trained for two months in this system after which the post-test was administered. Each nurse completed two questionnaires for measurement of their perceptions on usability and quality. We used descriptive statistics for demographic and descriptive data analysis. Paired t-test was used to compare pre- and post-data using SPSS. The findings showed significant differences in knowledge scores (p < 0.001), total score of clinical competencies (p < 0.001), and all ten assessed clinical competencies. The range of ratings given by participants varied on the six usability variables of Web-based training (2.96-4.23 from 5) and eight quality variables of Web-based training (3.58-4.37 from 5). Web-based education increased nurses' knowledge and competencies in diabetes. They positively evaluated Web-based learning usability and quality. It is hoped that this course will have a positive clinical outcomes.

Background Clinical care team members in Department of Veterans' Affairs (VA) facilities nationwide are working to integrate the use of Secure Messaging (SM) into care delivery and identify innovative uses. Identifying best practices for proactive use of SM is a key factor in its successful implementation and sustained use by VA clinical care team members and veterans. Objectives A collaborative project solicited input from VA clinical care teams about their local practices using SM to provide access to proactive patient-centered care for veterans and enhance workflow. Methods This project implemented a single-item cross-sectional qualitative electronic survey via internal e-mail to local coordinators in all 23 Veterans Integrated Service Networks (VISNs). Content analysis was used to manage descriptive data responses. Descriptive statistics described sample characteristics. Results VA clinical care team members across 15 of 23 VISNs responded to the questionnaire. Content analysis of 171 responses produced two global domains: (1) benefits of SM and (2) SM best practices. Benefits of SM use emphasize enhanced and efficient communication and increased access to care. Care team members incorporate SM into their daily clinical practices, using it to provide services before, during, and after clinical encounters as a best practice. SM users suggest improvements in veteran care, clinical team workflow, and efficient use of health resources. Clinical team members invested in the successful implementation of SM integrate SM into their daily practices to provide meaningful and useful veteran-centered care and improve workflow. Conclusion VA clinical care team members can use SM proactively to create an integrated SM culture. With adequate knowledge and motivation to proactively use this technology, all clinical team members within the VA system can replicate best practices shared by other clinical care teams to generate meaningful and useful interactions with SM to enrich veterans' health care experience.
When craft and science collide: Improving therapeutic practices through evidence-based innovations.
Justice, Laura M
2010-04-01
Evidence-based practice (EBP) is a model of clinical decision-making that is increasingly being advocated for use in the field of speech-language pathology. With the increased emphasis on scientific evidence as a form of knowledge important to EBP, clinicians may wonder whether their craft-based knowledge (i.e., knowledge derived from theory and practice), remains a legitimate form of knowledge for use in clinician decisions. This article describes forms of knowledge that may be used to address clinical questions, to include both craft and science. Additionally, the steps used when engaging in EBP are described so that clinicians understand when and how craft comes into play. The major premise addressed within this article is that craft is a legitimate form of knowledge and that engagement in EBP requires one to employ craft-based knowledge.

Research evidence continues to reveal findings important for health professionals' clinical practices, yet it is not consistently disseminated to those who can use it. The resulting deficits in knowledge and service provision may be especially pronounced in low- and middle-income countries that have greater resource constraints. Tuberculosis treatment is an important area for assessing professionals' knowledge and practices because of the effectiveness of existing treatments and recognized gaps in professionals' knowledge about treatment. This study surveyed 384 health professionals in China, India, Iran, and Mexico on their knowledge and practices related to tuberculosis treatment. Few respondents correctly answered all five knowledge questions (12%) or self-reported performing all five recommended clinical practices "often or very often" (3%). Factors associated with higher knowledge scores included clinical specialization and working with researchers. Factors associated with better practices included training in the care of tuberculosis patients, being based in a hospital, trusting systematic reviews of randomized controlled double-blind trials, and reading summaries of articles, reports, and reviews. This study highlights several strategies that may prove effective in improving health professionals' knowledge and practices related to tuberculosis treatment. Facilitating interactions with researchers and training in acquiring systematic reviews may be especially helpful. © The American Society of Tropical Medicine and Hygiene.

Clinical research plays a fundamental role in establishing new treatments. Clinical research coordinators are considered essential in clinical research, and medical professionals such as pharmacists often take on this role. Pharmacy students can be considered future candidates for this task. We used questionnaires to survey the knowledge of and attitudes toward registration trials and clinical research of pharmacy students at Tokushima University Hospital. All pharmacy students (103) to whom questionnaires were sent responded. Almost all respondents were aware of registration trials and clinical research. More than 90% were aware of the existence of clinical research coordinators, and about half (48.6%) understood their role. In clinical research terminology, most respondents were aware of informed consent and related issues, but fewer than 20% were aware of more practical things. In total, 29.1% and 40.8% of the respondents were willing to carry out and coordinate research. These findings suggest that pharmacy students have basic knowledge of clinical research and that many students are willing to carry out and coordinate clinical research. More practical exposure to clinical research may help to strengthen their future contribution. Further studies may help to determine how to provide education on registration trials and clinical research to pharmacy students.

At Intermountain Healthcare (Intermountain), executive clinical content experts are responsible for disseminating consistent evidence-based clinical content throughout the enterprise at the point-of-care. With a paper-based system it was difficult to ensure that current information was received and was being used in practice. With electronic information systems multiple applications were supplying similar, but different, vendor-licensed and locally-developed content. These issues influenced the consistency of clinical practice within the enterprise, jeopardized patient and clinician safety, and exposed the enterprise and its employees to potential financial penalties. In response to these issues Intermountain is developing a knowledge management infrastructure providing tools and services to support clinical content development, deployment, maintenance, and communication. The Intermountain knowledge management philosophy includes strategies guiding clinicians and consumers of health information to relevant best practice information with the intention of changing behaviors. This paper presents three case studies describing different information management problems identified within Intermountain, methods used to solve the problems, implementation challenges, and the current status of each project.
Evidence-based decision-making 7: Knowledge translation.
Manns, Braden J
2015-01-01
There is a significant gap between what is known and what is implemented by key stakeholders in practice (the evidence to practice gap). The primary purpose of knowledge translation is to address this gap, bridging evidence to clinical practice. The knowledge to action cycle is one framework for knowledge translation that integrates policy-makers throughout the research cycle. The knowledge to action cycle begins with the identification of a problem (usually a gap in care provision). After identification of the problem, knowledge creation is undertaken, depicted at the center of the cycle as a funnel. Knowledge inquiry is at the wide end of the funnel, and moving down the funnel, the primary data is synthesized into knowledge products in the form of educational materials, guidelines, decision aids, or clinical pathways. The remaining components of the knowledge to action cycle refer to the action of applying the knowledge that has been created. This includes adapting knowledge to local context, assessing barriers to knowledge use, selecting, tailoring implementing interventions, monitoring knowledge use, evaluating outcomes, and sustaining knowledge use. Each of these steps is connected by bidirectional arrows and ideally involves healthcare decision-makers and key stakeholders at each transition.

More than Anecdotes: Fishers’ Ecological Knowledge Can Fill Gaps for Ecosystem Modeling
Bevilacqua, Ana Helena V.; Carvalho, Adriana R.; Angelini, Ronaldo; Christensen, Villy
2016-01-01
Background Ecosystem modeling applied to fisheries remains hampered by a lack of local information. Fishers’ knowledge could fill this gap, improving participation in and the management of fisheries. Methodology The same fishing area was modeled using two approaches: based on fishers’ knowledge and based on scientific information. For the former, the data was collected by interviews through the Delphi methodology, and for the latter, the data was gathered from the literature. Agreement between the attributes generated by the fishers’ knowledge model and scientific model is discussed and explored, aiming to improve data availability, the ecosystem model, and fisheries management. Principal Findings The ecosystem attributes produced from the fishers’ knowledge model were consistent with the ecosystem attributes produced by the scientific model, and elaborated using only the scientific data from literature. Conclusions/Significance This study provides evidence that fishers’ knowledge may suitably complement scientific data, and may improve the modeling tools for the research and management of fisheries.

To evaluate a programme introducing quality improvement (QI) in nursing education. Betanien College of Nursing and clinical practices at hospitals in Bergen. 52 nursing students from a second year class working in 16 groups undertaking hospital based practical studies. Second year nursing students were assigned to follow a patient during a day's work and to record the processes of care from the patient's perspective. Data collected included waiting times, patient information, people in contact with the patient, investigations, and procedures performed. Students also identified aspects of practice that could be improved. They then attended a 2 day theoretical introductory course in QI and each group produced flow charts, cause/effect diagrams, and outlines of quality goals using structure, process, and results criteria to describe potential improvements. Each group produced a report of their findings. Main measures-A two-part questionnaire completed by the students before and after the intervention was used to assess the development of their understanding of QI. Evidence that students could apply a range of QI tools and techniques in the specific setting of a hospital ward was assessed from the final reports of their clinical attachments. The students had a significantly better knowledge of QI after the introductory course and group work than before it, and most students indicated that they considered the topic highly relevant for their later career. They reported that it was quite useful to observe one patient throughout one shift and, to some extent, they learned something new. Students found the introductory course and working in groups useful, and most thought the programme should be included in the curriculum for other nursing students. They considered it important for nurses in general to have knowledge about QI, indicating a high perceived relevance of the course. All 16 groups delivered reports of their group work which were approved by the tutors. Through the reports, all the groups demonstrated knowledge and ability to apply tools and techniques in their practical studies in a hospital setting. The introduction of a short experience-based programme into the practical studies of second year nursing students enabled them to learn about the concepts, tools, and techniques of continuous QI in a way that should provide them with the skills to undertake it as part of routine practice.

Semantic Web technology can considerably catalyze translational genetics and genomics research in medicine, where the interchange of information between basic research and clinical levels becomes crucial. This exchange involves mapping abstract phenotype descriptions from research resources, such as knowledge databases and catalogs, to unstructured datasets produced through experimental methods and clinical practice. This is especially true for the construction of mutation databases. This paper presents a way of harmonizing abstract phenotype descriptions with patient data from clinical practice, and querying this dataset about relationships between phenotypes and genetic variants, at different levels of abstraction. Due to the current availability of ontological and terminological resources that have already reached some consensus in biomedicine, a reuse-based ontology engineering approach was followed. The proposed approach uses the Ontology Web Language (OWL) to represent the phenotype ontology and the patient model, the Semantic Web Rule Language (SWRL) to bridge the gap between phenotype descriptions and clinical data, and the Semantic Query Web Rule Language (SQWRL) to query relevant phenotype-genotype bidirectional relationships. The work tests the use of semantic web technology in the biomedical research domain named cerebrotendinous xanthomatosis (CTX), using a real dataset and ontologies. A framework to query relevant phenotype-genotype bidirectional relationships is provided. Phenotype descriptions and patient data were harmonized by defining 28 Horn-like rules in terms of the OWL concepts. In total, 24 patterns of SWQRL queries were designed following the initial list of competency questions. As the approach is based on OWL, the semantic of the framework adapts the standard logical model of an open world assumption. This work demonstrates how semantic web technologies can be used to support flexible representation and computational inference mechanisms required to query patient datasets at different levels of abstraction. The open world assumption is especially good for describing only partially known phenotype-genotype relationships, in a way that is easily extensible. In future, this type of approach could offer researchers a valuable resource to infer new data from patient data for statistical analysis in translational research. In conclusion, phenotype description formalization and mapping to clinical data are two key elements for interchanging knowledge between basic and clinical research.

Clinical signs of malnutrition, starvation, cachexia and sarcopenia overlap, as they all imply muscle wasting to a various extent. However, the underlying mechanisms differ fundamentally and therefore distinction between these phenomena has therapeutic and prognostic implications. We aimed to determine whether dietitians in selected European countries have 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia, and use these terms in their daily clinical work. An anonymous online survey was performed among dietitians in Belgium, the Netherlands, Norway and Sweden. 'Sufficient knowledge' was defined as having mentioned at least two of the three common domains of malnutrition according to ESPEN definition of malnutrition (2011): 'nutritional balance', 'body composition' and 'functionality and clinical outcome', and a correct answer to three cases on starvation, cachexia and sarcopenia. Chi-square test was used to analyse differences in experience, work place and number of malnourished patients treated between dietitians with 'sufficient knowledge' vs. 'less sufficient knowledge'. 712/7186 responded to the questionnaire, of which data of 369 dietitians were included in the analysis (5%). The term 'malnutrition' is being used in clinical practice by 88% of the respondents. Starvation, cachexia and sarcopenia is being used by 3%, 30% and 12% respectively. The cases on starvation, cachexia and sarcopenia were correctly identified by 58%, 43% and 74% respectively. 13% of the respondents had 'sufficient knowledge'. 31% of the respondents identified all cases correctly. The proportion of respondents with 'sufficient knowledge' was significantly higher in those working in a hospital or in municipality (16%, P < 0.041), as compared to those working in other settings (7%). The results of our survey among dietitians in four European countries show that the percentage of dietitians with 'sufficient knowledge' regarding malnutrition, starvation, cachexia and sarcopenia is unsatisfactory (13%). The terms starvation, cachexia and sarcopenia are not often used by dietitians in daily clinical work. As only one-third (31%) of dietitians identified all cases correctly, the results of this study seem to indicate that nutrition-related disorders are suboptimally recognized in clinical practice, which might have a negative impact on nutritional treatment. The results of our study require confirmation in a larger sample of dietitians. Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.
Optimizing biomedical science learning in a veterinary curriculum: a review.
Warren, Amy L; Donnon, Tyrone
2013-01-01
As veterinary medical curricula evolve, the time dedicated to biomedical science teaching, as well as the role of biomedical science knowledge in veterinary education, has been scrutinized. Aside from being mandated by accrediting bodies, biomedical science knowledge plays an important role in developing clinical, diagnostic, and therapeutic reasoning skills in the application of clinical skills, in supporting evidence-based veterinary practice and life-long learning, and in advancing biomedical knowledge and comparative medicine. With an increasing volume and fast pace of change in biomedical knowledge, as well as increased demands on curricular time, there has been pressure to make biomedical science education efficient and relevant for veterinary medicine. This has lead to a shift in biomedical education from fact-based, teacher-centered and discipline-based teaching to applicable, student-centered, integrated teaching. This movement is supported by adult learning theories and is thought to enhance students' transference of biomedical science into their clinical practice. The importance of biomedical science in veterinary education and the theories of biomedical science learning will be discussed in this article. In addition, we will explore current advances in biomedical teaching methodologies that are aimed to maximize knowledge retention and application for clinical veterinary training and practice.

This study was to explore the relationship between clinical performance examination (CPX) achievement and epistemological beliefs to investigate the potentials of epistemological beliefs in ill-structured medical problem solving tasks. We administered the epistemological beliefs questionnaire (EBQ) to fourth-year medical students and correlated the results with their CPX scores. The EBQ comprised 61 items reflecting five belief systems: certainty of knowledge, source of knowledge, rigidity of learning, ability to learn, and speed of knowledge acquisition. The CPX included scores for history taking, physical examination, and patient-physician interaction. The higher epistemological beliefs group obtained significantly higher scores on the CPX with regard to history taking and patient-physician interaction. The epistemological beliefs scores on certainty of knowledge and source of knowledge were significantly positively correlated with patient-physician interaction. The epistemological beliefs scores for ability to learn were significantly positively correlated with those for history taking, physical examination, and patient-physician interaction. Students with more sophisticated and advanced epistemological beliefs stances used more comprehensive and varied approaches in the patient-physician interaction. Therefore, educational efforts that encourage discussions pertaining to epistemological views should be considered to improve clinical reasoning and problem-solving competence in the clinic setting.

Inferring precise phenotypic patterns from population-scale clinical data is a core computational task in the development of precision, personalized medicine. The traditional approach uses supervised learning, in which an expert designates which patterns to look for (by specifying the learning task and the class labels), and where to look for them (by specifying the input variables). While appropriate for individual tasks, this approach scales poorly and misses the patterns that we don't think to look for. Unsupervised feature learning overcomes these limitations by identifying patterns (or features) that collectively form a compact and expressive representation of the source data, with no need for expert input or labeled examples. Its rising popularity is driven by new deep learning methods, which have produced high-profile successes on difficult standardized problems of object recognition in images. Here we introduce its use for phenotype discovery in clinical data. This use is challenging because the largest source of clinical data - Electronic Medical Records - typically contains noisy, sparse, and irregularly timed observations, rendering them poor substrates for deep learning methods. Our approach couples dirty clinical data to deep learning architecture via longitudinal probability densities inferred using Gaussian process regression. From episodic, longitudinal sequences of serum uric acid measurements in 4368 individuals we produced continuous phenotypic features that suggest multiple population subtypes, and that accurately distinguished (0.97 AUC) the uric-acid signatures of gout vs. acute leukemia despite not being optimized for the task. The unsupervised features were as accurate as gold-standard features engineered by an expert with complete knowledge of the domain, the classification task, and the class labels. Our findings demonstrate the potential for achieving computational phenotype discovery at population scale. We expect such data-driven phenotypes to expose unknown disease variants and subtypes and to provide rich targets for genetic association studies.

The purpose of this study was to investigate the effects of 1st-grade number knowledge tutoring with contrasting forms of practice. Tutoring occurred 3 times per week for 16 weeks. In each 30-min session, the major emphasis (25 min) was number knowledge; the other 5 min provided practice in 1 of 2 forms. Nonspeeded practice reinforced relations and principles addressed in number knowledge tutoring. Speeded practice promoted quick responding and use of efficient counting procedures to generate many correct responses. At-risk students were randomly assigned to number knowledge tutoring with speeded practice ( n = 195), number knowledge tutoring with nonspeeded practice ( n = 190), and control (no tutoring, n = 206). Each tutoring condition produced stronger learning than control on all 4 mathematics outcomes. Speeded practice produced stronger learning than nonspeeded practice on arithmetic and 2-digit calculations, but effects were comparable on number knowledge and word problems. Effects of both practice conditions on arithmetic were partially mediated by increased reliance on retrieval, but only speeded practice helped at-risk children compensate for weak reasoning ability.
Effects of Working Memory Capacity and Domain Knowledge on Recall for Grocery Prices.
Bermingham, Douglas; Gardner, Michael K; Woltz, Dan J
2016-01-01
Hambrick and Engle (2002) proposed 3 models of how domain knowledge and working memory capacity may work together to influence episodic memory: a "rich-get-richer" model, a "building blocks" model, and a "compensatory" model. Their results supported the rich-get-richer model, although later work by Hambrick and Oswald (2005) found support for a building blocks model. We investigated the effects of domain knowledge and working memory on recall of studied grocery prices. Working memory was measured with 3 simple span tasks. A contrast of realistic versus fictitious foods in the episodic memory task served as our manipulation of domain knowledge, because participants could not have domain knowledge of fictitious food prices. There was a strong effect for domain knowledge (realistic food-price pairs were easier to remember) and a moderate effect for working memory capacity (higher working memory capacity produced better recall). Furthermore, the interaction between domain knowledge and working memory produced a small but significant interaction in 1 measure of price recall. This supported the compensatory model and stands in contrast to previous research.

The current volume and complexity of genetic tests, and the molecular genetics knowledge and health knowledge related to interpretation of the results of those tests, are rapidly outstripping the ability of individual clinicians to recall, understand and convey to their patients information relevant to their care. The tailoring of molecular genetics knowledge and health knowledge in clinical settings is important both for the provision of personalized medicine and to reduce clinician information overload. In this paper we describe the incorporation, customization and demonstration of molecular genetic data (mainly sequence variants), molecular genetics knowledge and health knowledge into a standards-based electronic health record (EHR) prototype developed specifically for this study. We extended the CCR (Continuity of Care Record), an existing EHR standard for representing clinical data, to include molecular genetic data. An EHR prototype was built based on the extended CCR and designed to display relevant molecular genetics knowledge and health knowledge from an existing knowledge base for cystic fibrosis (OntoKBCF). We reconstructed test records from published case reports and represented them in the CCR schema. We then used the EHR to dynamically filter molecular genetics knowledge and health knowledge from OntoKBCF using molecular genetic data and clinical data from the test cases. The molecular genetic data were successfully incorporated in the CCR by creating a category of laboratory results called "Molecular Genetics" and specifying a particular class of test ("Gene Mutation Test") in this category. Unlike other laboratory tests reported in the CCR, results of tests in this class required additional attributes ("Molecular Structure" and "Molecular Position") to support interpretation by clinicians. These results, along with clinical data (age, sex, ethnicity, diagnostic procedures, and therapies) were used by the EHR to filter and present molecular genetics knowledge and health knowledge from OntoKBCF. This research shows a feasible model for delivering patient sequence variants and presenting tailored molecular genetics knowledge and health knowledge via a standards-based EHR system prototype. EHR standards can be extended to include the necessary patient data (as we have demonstrated in the case of the CCR), while knowledge can be obtained from external knowledge bases that are created and maintained independently from the EHR. This approach can form the basis for a personalized medicine framework, a more comprehensive standards-based EHR system and a potential platform for advancing translational research by both disseminating results and providing opportunities for new insights into phenotype-genotype relationships.

To explore interprofessional attitudes arising from shared learning in mental health. Inter-professional education in healthcare is a priority area for improving team-working and communication. Many studies have attempted to evaluate its benefits and challenges, although few emanate from the mental health arena. However, producing evidence to link educational input with clinical outcomes is notoriously difficult. This project attempted to produce evidence for changes in interprofessional attitudes and stereotypes. Mental health nursing students and clinical psychology trainees participated in inter-professional education. An evaluation tool was designed to evaluate the experience and outcomes, and to consider implications for interprofessional working. There was an increase in clarity regarding roles, approaches and resources, and how to collaborate in practice. There was no significant change in professional identity. Many challenges were identified, including differences in academic level, previous experience, expectations, assessment, motivation and effort. Despite the challenges, it remains important to offer collaboration with future mental health colleagues as a foundation for effective team-working. Recommendations are made for creating inter-professional education opportunities for diverse student groups. Mental health professionals need to work effectively in multidisciplinary teams. Drawing on available guidance, managers should encourage and support team members to undertake shared learning where possible, both within clinical settings and through more formal educational provision. In this way, managers can facilitate collaborative relationships which will pay dividends for the provision of effective mental health care. This project adds to the limited knowledge currently available on interprofessional learning and attitudes within a mental health context.

The National Institute of Health's concept of team science is a means of addressing complex clinical problems by applying conceptual and methodological approaches from multiple disciplines and health professions. The ultimate goal is the improved quality of care of patients with an emphasis on better population health outcomes. Collaborative research practice occurs when researchers from >1 health-related profession engage in scientific inquiry to jointly create and disseminate new knowledge to clinical and research health professionals in order to provide the highest quality of patient care to improve population health outcomes. Training of clinicians and researchers is necessary to produce clinically relevant evidence upon which to base patient care for disease management and empirically guided team-based patient care. In this study, we hypothesized that team science is an example of effective and impactful interprofessional collaborative research practice. To assess this hypothesis, we examined the contemporary literature on the science of team science (SciTS) produced in the past 10 years (2005–2015) and related the SciTS to the overall field of interprofessional collaborative practice, of which collaborative research practice is a subset. A modified preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach was employed to analyze the SciTS literature in light of the general question: Is team science an example of interprofessional collaborative research practice? After completing a systematic review of the SciTS literature, the posed hypothesis was accepted, concluding that team science is a dimension of interprofessional collaborative practice. PMID:27619555

The National Institute of Health's concept of team science is a means of addressing complex clinical problems by applying conceptual and methodological approaches from multiple disciplines and health professions. The ultimate goal is the improved quality of care of patients with an emphasis on better population health outcomes. Collaborative research practice occurs when researchers from >1 health-related profession engage in scientific inquiry to jointly create and disseminate new knowledge to clinical and research health professionals in order to provide the highest quality of patient care to improve population health outcomes. Training of clinicians and researchers is necessary to produce clinically relevant evidence upon which to base patient care for disease management and empirically guided team-based patient care. In this study, we hypothesized that team science is an example of effective and impactful interprofessional collaborative research practice. To assess this hypothesis, we examined the contemporary literature on the science of team science (SciTS) produced in the past 10 years (2005-2015) and related the SciTS to the overall field of interprofessional collaborative practice, of which collaborative research practice is a subset. A modified preferred reporting items for systematic reviews and meta-analyses (PRISMA) approach was employed to analyze the SciTS literature in light of the general question: Is team science an example of interprofessional collaborative research practice? After completing a systematic review of the SciTS literature, the posed hypothesis was accepted, concluding that team science is a dimension of interprofessional collaborative practice.

The challenges of knowledge translation in behavioural health care are unique to this field for a variety of reasons including the fact that effective treatment is invariably embedded in a strong relationship between practitioners and the people they serve. Practitioners' knowledge gained from experience and intuition become an even more important consideration in the knowledge translation process since clinicians are, in fact, a component of most treatments. Communication of findings from science must be conceptualized with sensitivity to this reality. Considering knowledge translation as a communication process suggests the application of contemporary theories of communication which emphasize the creation of shared meaning over the transmission of knowledge from one person to the next. In this context outcomes management approaches to create a learning environment within clinical practices that facilitate the goals of knowledge transfer while respecting that the scientific enterprise is neither the sole nor primary repository of knowledge.
MMPI-2-RF characteristics of individuals with interstitial cystitis.
Fazio, Rachel L; Wunderlich, Ted; Wilson, Nicolas; Akeson, Steven
2014-11-01
This study aimed to describe the psychological functioning of interstitial cystitis/bladder pain syndrome patients utilizing MMPI-2-RF scoring. The MMPI-2 was administered to 60 individuals who reported a diagnosis of IC. Responses were scored in the MMPI-2-RF format. Fifty-one protocols were deemed valid. Elevations were discovered on scales FBS-r (symptom validity), RC1 (somatic complaints), and MLS (malaise). Participants were split into two groups based on extreme elevations on RC1; the high RC1 group produced higher scores on 39 scales including clinically significant elevations on 17 scales. Over 25% of this sample had an emotional component to their physical concerns. This knowledge about the psychological characteristics of IC patients may have clinical utility for physicians and other treatment providers. The results argue strongly for psychological evaluation as a component of IC diagnosis and treatment. Those with significant emotional overlay to their somatic complaints may be best managed through psychological interventions and minimally invasive treatments. Copyright © 2014 Elsevier Inc.

The ability to differentially alter specific brain functions via deep brain stimulation (DBS) represents a monumental advance in clinical neuroscience, as well as within medicine as a whole. Despite the efficacy of DBS in the treatment of movement disorders, for which it is often the gold-standard therapy when medical management becomes inadequate, the mechanisms through which DBS in various brain targets produces therapeutic effects is still not well understood. This limited knowledge is a barrier to improving efficacy and reducing side effects in clinical brain stimulation. A field of study related to assessing the network effects of DBS is gradually emerging that promises to reveal aspects of the underlying pathophysiology of various brain disorders and their response to DBS that will be critical to advancing the field. This review summarizes the nascent literature related to network effects of DBS measured by cerebral blood flow and metabolic imaging, functional imaging, and electrophysiology (scalp and intracranial electroencephalography and magnetoencephalography) in order to establish a framework for future studies.

Cholerae is a grave and acute bacterial intestine infection which is caused by a bacilo, V. cholerae 01, that produces toxic products. Its clinical symptoms range from abundant liquid diarrhoea combined with vomiting and rapid dehydration. It is highly lethal when right treatment is not applied. There are also cases of cholera where victims do not show any symptoms of it, that is asymptomatic carriers. Any clinical suspicion of cholerae has to be corroborated by epidemiological data and its diagnostic confirmation should be done by isolating the bacteria, V. cholerae. When beginning the treatment, it is not necessary to confirm the diagnostic and this is based on the restitution of the liquids lost through vomiting and facing using any methods that are recommended for any other type of diarrhoea. The antimicrobial treatment is used only for grave cases. This present revision includes recent knowledge about cholerae emphasising on the effective management of cases through an adequate use of right treatment methods and also using the principal prevention measures against dissemination of this disease.
The use of simulation in teaching the basic sciences.
Eason, Martin P
2013-12-01
To assess the current use of simulation in medical education, specifically, the teaching of the basic sciences to accomplish the goal of improved integration. Simulation is increasingly being used by the institutions to teach the basic sciences. Preliminary data suggest that it is an effective tool with increased retention and learner satisfaction. Medical education is undergoing tremendous change. One of the directions of that change is increasing integration of the basic and clinical sciences to improve the efficiency and quality of medical education, and ultimately to improve the patient care. Integration is thought to improve the understanding of basic science conceptual knowledge and to better prepare the learners for clinical practice. Simulation because of its unique effects on learning is currently being successfully used by many institutions as a means to produce that integration through its use in the teaching of the basic sciences. Preliminary data indicate that simulation is an effective tool for basic science education and garners high learner satisfaction.
Tumor-related interleukins: old validated targets for new anti-cancer drug development.

In-depth knowledge of cancer molecular and cellular mechanisms have revealed a strong regulation of cancer development and progression by the inflammation which orchestrates the tumor microenvironment. Immune cells, residents or recruited, in the inflammation milieu can have rather contrasting effects during cancer development. Accumulated clinical and experimental data support the notion that acute inflammation could exert an immunoprotective effect leading to tumor eradication. However, chronic immune response promotes tumor growth and invasion. These reactions are mediated by soluble mediators or cytokines produced by either host immune cells or tumor cells themselves. Herein, we provide an overview of the current understanding of the role of the best-validated cytokines involved in tumor progression, IL-1, IL-4 and IL-6; in addition to IL-2 cytokines family, which is known to promote tumor eradication by immune cells. Furthermore, we summarize the clinical attempts to block or bolster the effect of these tumor-related interleukins in anti-cancer therapy development.

Genetics is an essential subject to be mastered by health professional students of all types. However, technological advances in genomics and recent pedagogical research have changed the way in which many medical training programs teach genetics to their students. These advances favor a more experience-based education focused primarily on developing student's critical thinking skills. In this review, we examine the current state of genetics education at both the preclinical and clinical levels and the ways in which medical and pedagogical research have guided reforms to current and emerging teaching practices in genetics. We discover exciting trends taking place in which genetics is integrated with other scientific disciplines both horizontally and vertically across medical curricula to emphasize training in scientific critical thinking skills among students via the evaluation of clinical evidence and consultation of online databases. These trends will produce future health professionals with the skills and confidence necessary to embrace the new tools of medical practice that have emerged from scientific advances in genetics, genomics, and bioinformatics.
Distance learning--an educational tool for developing countries.
Dobson, M B
2000-01-01
Many anaesthetists in small hospitals and developing countries have poor access to educational materials. The use of electronic means of publication and distribution, combined with the concepts of distance learning, can lead to better levels of knowledge and clinical practice. A project based on these principles has been set up in Zimbabwe, and is proving helpful to both trainers and trainees. All District Hospitals have been visited, and trainees in them identified. A survey has been completed to identify the subject areas in which training is most necessary. Trainees have been provided with reference materials on CD-ROM which they can access by computer (each hospital has a computer). Specialist anaesthesiologists in the country are producing interactive tutorials which can be sent out by e-mail to every hospital, and these are backed up by a programme of regular visits, seminars and clinical teaching. The programme is proving helpful to both trainees and tutors, and has the potential to be used in the future in other developing countries.
From embryonic stem cells to functioning germ cells: science, clinical and ethical perspectives.
Kiatpongsan, Sorapop
2007-10-01
Embryonic stem cells have been well recognized as cells having a versatile potential to differentiate into all types of cells in the body including germ cells. There are many research studies focusing on the differentiation processes and protocols to derive various types of somatic cells from embryonic stem cells. However, germ cells have unique differentiation process and developmental pathway compared with somatic cells. Consequently, they will require different differentiation protocols and special culture techniques. More understanding and established in vitro systems for gametogenesis will greatly contribute to further progression of knowledge and technology in germ cell biology, reproductive biology and reproductive medicine. Moreover if oocytes can be efficiently produced in vitro, this will play an important role on progression in nuclear transfer and nuclear reprogramming technology. The present article will provide concise review on past important discoveries, current ongoing studies and future views of this challenging research area. An ethical perspective has also been proposed to give comprehensive summary and viewpoint for future clinical application.

Cardiomyopathies (CMPs) are an increasingly recognized cause of heart failure and sudden death, particularly in young patients. Since their original description, major advances were achieved in the phenotype knowledge, natural history, and nosography of CMPs leading to different classification systems and therapies. However, a deeper knowledge of different causes, genotype-phenotype link, and natural history in different disease stages (preclinical, overt disease, and end-stage disease) according to a recognized standard of care (ie, international guidelines) is needed. Clinical registries can fill gaps in our knowledge regarding the uncovered issues on cause, clinical course, and management of CMPs. Copyright © 2017 Elsevier Inc. All rights reserved.

Despite the concerted effort of modern undergraduate curriculum designers, the ability to integrate basic sciences in clinical rotations is an ongoing problem in medical education. Students and newly qualified doctors themselves report worry about the effect this has on their clinical performance. There are examples in the literature to support development of attempts at integrating such aspects, but this "vertical integration" has proven to be difficult. We designed an expert-led integrated program using dissection of porcine hearts to improve the use of cardiac basic sciences in clinical medical students' decision-making processes. To our knowledge, this is the first time in the United Kingdom that an animal model has been used to teach undergraduate clinical anatomy to medical students to direct wider application of knowledge. Action research methodology was used to evaluate the local curriculum and assess learners needs, and the agreed teaching outcomes, methods, and delivery outline were established. A total of 18 students in the clinical years of their degree program attended, completing precourse and postcourse multichoice questions examinations and questionnaires to assess learners' development. Student's knowledge scores improved by 17.5% (p = 0.01; students t-test). Students also felt more confident at applying underlying knowledge to decision-making and diagnosis in clinical medicine. An expert teacher (consultant surgeon) was seen as beneficial to students' understanding and appreciation. This study outlines how the development of a teaching intervention using porcine-based methods successfully improved both student's knowledge and application of cardiac basic sciences. We recommend that clinicians fully engage with integrating previously learnt underlying sciences to aid students in developing decision-making and diagnostic skills as well as a deeper approach to learning.

Clinical practice is a pivotal part of nursing education. It provides students with the opportunity to put the knowledge and skills they have acquired from lectures into practice with real patients, under the guidance of registered nurses. Clinical experience is also essential for shaping the nursing students' identity as future professional nurses. There is a lack of knowledge and understanding of the ways in which students learn practical skills and apply knowledge within and across different contexts, i.e. how they apply clinical skills, learnt in the laboratory in university settings, in the clinical setting. The aim of this study was therefore to explore how nursing students describe, and use, their prior experiences related to practical skills during their clinical practice. An ethnographic case study design was used. Fieldwork included participant observations (82 h), informal conversations, and interviews ( n = 7) that were conducted during nursing students' ( n = 17) clinical practice at an emergency department at a university hospital in Sweden. The overarching theme identified was "Learning about professional identities with respect to situated power". This encompasses tensions in students' learning when they are socialized into practical skills in the nursing profession. This overarching theme consists of three sub-themes: "Embodied knowledge", "Divergent ways of assessing and evaluating knowledge" and "Balancing approaches". Nursing students do not automatically possess the ability to transfer knowledge from one setting to another; rather, their development is shaped by their experiences and interactions with others when they meet real patients. The study revealed different ways in which students navigated tensions related to power differentials. Reflecting on actions is a prerequisite for developing and learning practical skills and professional identities. This highlights the importance of both educators' and the preceptors' roles for socializing students in this process.

For health scientists, knowledge translation refers to the process of facilitating uptake of knowledge into clinical practice or decision making. Since high-quality clinical research that is not applied cannot improve outcomes, knowledge translation is critical for realizing the value and potential for all types of health research. Knowledge translation is particularly relevant for areas within health care where gaps in care are known to exist, which is the case for some areas of management for people with chronic kidney disease (CKD), including assessment of proteinuria. Given that proteinuria is a key marker of cardiovascular and renal risk, forthcoming international practice guidelines will recommend including proteinuria within staging systems for CKD. While this revised staging system will facilitate identification of patients at higher risk for progression of CKD and mortality who benefit from intervention, strategies to ensure its appropriate uptake will be particularly important. This article describes key elements of effective knowledge translation strategies based on the knowledge-to-action cycle framework and describes options for effective knowledge translation interventions related to the new CKD guidelines, focusing on recommendations related to assessment for proteinuria specifically. The article also presents findings from a multidisciplinary meeting aimed at developing knowledge translation intervention strategies, with input from key stakeholders (researchers, knowledge users, decision makers and collaborators), to facilitate implementation of this guideline. These considerations are relevant for dissemination and implementation of guidelines on other topics and in other clinical settings.
Newly graduated nurses' use of knowledge sources: a meta-ethnography.

To advance evidence on newly graduated nurses' use of knowledge sources. Clinical decisions need to be evidence-based and understanding the knowledge sources that newly graduated nurses use will inform both education and practice. Qualitative studies on newly graduated nurses' use of knowledge sources are increasing though generated from scattered healthcare contexts. Therefore, a metasynthesis of qualitative research on what knowledge sources new graduates use in decision-making was conducted. Meta-ethnography. Nineteen reports, representing 17 studies, published from 2000-2014 were identified from iterative searches in relevant databases from May 2013-May 2014. Included reports were appraised for quality and Noblit and Hare's meta-ethnography guided the interpretation and synthesis of data. Newly graduated nurses' use of knowledge sources during their first 2-year postgraduation were interpreted in the main theme 'self and others as knowledge sources,' with two subthemes 'doing and following' and 'knowing and doing,' each with several elucidating categories. The metasynthesis revealed a line of argument among the report findings underscoring progression in knowledge use and perception of competence and confidence among newly graduated nurses. The transition phase, feeling of confidence and ability to use critical thinking and reflection, has a great impact on knowledge sources incorporated in clinical decisions. The synthesis accentuates that for use of newly graduated nurses' qualifications and skills in evidence-based practice, clinical practice needs to provide a supportive environment which nurtures critical thinking and questions and articulates use of multiple knowledge sources. © 2016 John Wiley & Sons Ltd.
Developing practical knowledge content of emergency nursing professionals.
Chu, Wen; Hsu, Li-Ling
2011-06-01
There is a paucity of published research on clinical or practical nursing knowledge. The ways that nurses acquire, develop, and maintain emergency room (ER) nursing care skills is a research area, in particular, that deserves further investigation. This study examined clinical setting learning processes to better understand the practical knowledge content of ER nurses. This study used a phenomenological approach and in-depth interviews of 10 nurses. Each participant had at least 3 years of ER experience. Researchers used Moustakas' method to analyze interview data. Findings were checked for credibility, transferability, dependability, and confirmability. The authors identified four major practical knowledge themes for ER professionals. These were (a) basic emergency treatment procedure routines and symptom management; (b) disease mechanisms, pharmacodynamics, and treatment responses; (c) newly identified diseases, updated emergency treatments and techniques, and medical treatment discussions; and (d) identifying nursing values including nursing attitudes and continuing patient care. Participants in this study had experience with the first three themes and successfully combined various types of nursing knowledge in their nursing care duties. Only few participants indicated experience with the fourth theme. Findings clarify that clinical or practical knowledge in ER nurses evolves first from declarative knowledge (e.g., basic emergency treatment routines and operating procedures) to procedural knowledge (e.g., instructions from supervisors, actual practice, and drills) to conditional knowledge (e.g., observation and treatment involving direct interactions with patients). Nurses should combine and apply the various knowledge types in their nursing practice to assess comprehensively each patient's condition and administer effective treatment and service.
Newly graduated nurses' use of knowledge sources in clinical decision-making: an ethnographic study.

To explore which knowledge sources newly graduated nurses' use in clinical decision-making and why and how they are used. In spite of an increased educational focus on skills and competencies within evidence-based practice, newly graduated nurses' ability to use components within evidence-based practice with a conscious and reflective use of research evidence has been described as being poor. To understand why, it is relevant to explore which other knowledge sources are used. This may shed light on why research evidence is sparsely used and ultimately inform approaches to strengthen the knowledgebase used in clinical decision-making. Ethnographic study using participant-observation and individual semistructured interviews of nine Danish newly graduated nurses in medical and surgical hospital settings. Newly graduates use of knowledge sources was described within three main structures: 'other', 'oneself' and 'gut feeling'. Educational preparation, transition into clinical practice and the culture of the setting influenced the knowledge sources used. The sources ranged from overt easily articulated knowledge sources to covert sources that were difficult to articulate. The limited articulation of certain sources inhibited the critical reflection on the reasoning behind decisions. Reflection is a prerequisite for an evidence-based practice where decisions should be transparent in order to consider if other evidentiary sources could be used. Although there is a complexity and variety to knowledge sources used, there is an imbalance with the experienced nurse playing a key role, functioning both as predominant source and a role model as to which sources are valued and used in clinical decision-making. If newly graduates are to be supported in an articulate and reflective use of a variety of sources, they have to be allocated to experienced nurses who model a reflective, articulate and balanced use of knowledge sources. © 2016 John Wiley & Sons Ltd.

Integrative understanding of preclinical and clinical data is imperative to enable informed decisions and reduce the attrition rate during drug development. The volume and variety of data generated during drug development have increased tremendously. A new information model and visualization tool was developed to effectively utilize all available data and current knowledge. The Knowledge Plot integrates preclinical, clinical, efficacy and safety data by adding two concepts: knowledge from the different disciplines and protein binding. Internal and public available data were gathered and processed to allow flexible and interactive visualizations. The exposure was expressed as the unbound concentration of the compound and the treatment effect was normalized and scaled by including expert opinion on what a biologically meaningful treatment effect would be. The Knowledge Plot has been applied both retrospectively and prospectively in project teams in a number of different therapeutic areas, resulting in closer collaboration between multiple disciplines discussing both preclinical and clinical data. The Plot allows head to head comparisons of compounds and was used to support Candidate Drug selections and differentiation from comparators and competitors, back translation of clinical data, understanding the predictability of preclinical models and assays, reviewing drift in primary endpoints over the years, and evaluate or benchmark compounds in due diligence comparing multiple attributes. The Knowledge Plot concept allows flexible integration and visualization of relevant data for interpretation in order to enable scientific and informed decision-making in various stages of drug development. The concept can be used for communication, decision-making, knowledge management, and as a forward and back translational tool, that will result in an improved understanding of the competitive edge for a particular project or disease area portfolio. In addition, it also builds up a knowledge and translational continuum, which in turn will reduce the attrition rate and costs of clinical development by identifying poor candidates early.

Heart disease is the leading killer of women and remains poorly recognized in high-risk groups. We assessed baseline knowledge gaps and efficacy of a survey-based educational intervention. Four hundred seventy-two women in clinical settings completed pre-/post-surveys for knowledge of: heart disease as the leading killer, risk factors (general and personal levels), heart attack/stroke symptoms, and taking appropriate emergency action. They received a clinic-based educational intervention delivered by healthcare professionals in the course of their clinical care. Change score analyses tested pre-/post-differences in knowledge after the educational intervention, comparing proportions by race, ethnicity, and urban/nonurban status. Knowledge and awareness was low in all groups, especially for American Indian women (p < 0.05). Awareness was overall highest for heart disease as the leading killer, but it was the lowest for taking appropriate action (13% of Hispanic, 13% of American Indian, 29% of African American, and 18% of nonurban women; p < 0.05). For all women, knowledge of the major risk factors was low (58%) as was knowledge of their personal levels for risk factors (73% awareness for hypertension, 54% for cholesterol, and 50% for diabetes). The intervention was effective (% knowledge gain) in all groups of women, particularly for raising awareness of: (1) heart disease as the leading killer in American Indian (25%), Hispanic (18%), and nonurban (15%) women; (2) taking appropriate action for American Indian (80%), African American (64%), non-Hispanic (55%), and urban (56%) women; (3) heart disease risk factors for Hispanic (56%) and American Indian (47%) women; and (4) heart disease and stroke symptoms in American Indian women (54% and 25%, respectively). Significant knowledge gaps persist for heart disease in high-risk women, suggesting that these gaps and groups should be targeted by educational programs. We specify areas of need, and we demonstrate efficacy of a clinic-based educational intervention that can be of utility to busy healthcare professionals.

Racial, ethnic and economic disparities in cancer rates, outcomes, and clinical trials participation persist despite significant research. We examined barriers to clinical trials enrollment among Chinese patients, and developed a navigation program for Chinese gynecologic and breast cancer patients. Six bilingual navigators were trained and a navigator assigned to each patient for at least 2 months. All patients received a clinical trials booklet in Chinese and English. Data collection included pre-and post-navigation surveys, intake forms, and documentation of navigation encounters. Between July 2010 and May 31, 2011, we recruited 28 breast and gynecologic cancer patients. Patients averaged 317 min of navigation (range 63-1,852) during 8 sessions (range 3-28). They improved in 4 of 10 true-false knowledge statements about clinical trials. A patient navigation program for Chinese-speaking cancer patients is feasible. It results in high patient satisfaction rates and modest improvements in clinical trials knowledge and participation.
RN, CIO: an executive informatics career.
Staggers, Nancy; Lasome, Caterina E M
2005-01-01
The Chief Information Officer (CIO) position is a viable new career track for clinical informaticists. Nurses, especially informatics nurses, are uniquely positioned for the CIO role because of their operational knowledge of clinical processes, communication skills, systems thinking abilities, and knowledge about information structures and processes. This article describes essential knowledge and skills for the CIO executive position. Competencies not typical to nurses can be learned and developed, particularly strategic visioning and organizational finesse. This article concludes by describing career development steps toward the CIO position: leadership and management; healthcare operations; organizational finesse; and informatics knowledge, processes, methods, and structures.

With so much emphasis on reducing attrition and becoming more efficient in the delivery of healthcare, there are many opportunities to leverage existing clinical data in drug development and to foster the practice of reverse translation. The application of quantitative approaches to convert clinical trial and real-world data to knowledge will continue to drive innovation. Herein we discuss recent examples of reverse translation and consider future opportunities to capture critical clinical knowledge to inform decision-making in drug development. © 2017 The Authors.

An integrative model for in-silico clinical-genomics discovery science.
Lussier, Yves A; Sarkar, Indra Nell; Cantor, Michael
2002-01-01
Human Genome discovery research has set the pace for Post-Genomic Discovery Research. While post-genomic fields focused at the molecular level are intensively pursued, little effort is being deployed in the later stages of molecular medicine discovery research, such as clinical-genomics. The objective of this study is to demonstrate the relevance and significance of integrating mainstream clinical informatics decision support systems to current bioinformatics genomic discovery science. This paper is a feasibility study of an original model enabling novel "in-silico" clinical-genomic discovery science and that demonstrates its feasibility. This model is designed to mediate queries among clinical and genomic knowledge bases with relevant bioinformatic analytic tools (e.g. gene clustering). Briefly, trait-disease-gene relationships were successfully illustrated using QMR, OMIM, SNOMED-RT, GeneCluster and TreeView. The analyses were visualized as two-dimensional dendrograms of clinical observations clustered around genes. To our knowledge, this is the first study using knowledge bases of clinical decision support systems for genomic discovery. Although this study is a proof of principle, it provides a framework for the development of clinical decision-support-system driven, high-throughput clinical-genomic technologies which could potentially unveil significant high-level functions of genes.
Teaching and Assessing Clinical Reasoning Skills.
Modi, Jyoti Nath; Anshu; Gupta, Piyush; Singh, Tejinder
2015-09-01
Clinical reasoning is a core competency expected to be acquired by all clinicians. It is the ability to integrate and apply different types of knowledge, weigh evidence critically and reflect upon the process used to arrive at a diagnosis. Problems with clinical reasoning often occur because of inadequate knowledge, flaws in data gathering and improper approach to information processing. Some of the educational strategies which can be used to encourage acquisition of clinical reasoning skills are: exposure to a wide variety of clinical cases, activation of previous knowledge, development of illness scripts, sharing expert strategies to arrive at a diagnosis, forcing students to prioritize differential diagnoses; and encouraging reflection, metacognition, deliberate practice and availability of formative feedback. Assessment of clinical reasoning abilities should be done throughout the training course in diverse settings. Use of scenario based multiple choice questions, key feature test and script concordance test are some ways of theoretically assessing clinical reasoning ability. In the clinical setting, these skills can be tested in most forms of workplace based assessment. We recommend that clinical reasoning must be taught at all levels of medical training as it improves clinician performance and reduces cognitive errors.
