Developing a probabilistic graphical structure from a model of mental-health clinical risk expertise

This paper explores the process of developing a principled approach for translating a model of mental-health risk expertise into a probabilistic graphical structure. The Galatean Risk Screening Tool [1] is a psychological model for mental health risk assessment based on fuzzy sets. This paper details how the knowledge encapsulated in the psychological model was used to develop the structure of the probability graph by exploiting the semantics of the clinical expertise. These semantics are formalised by a detailed specification for an XML structure used to represent the expertise. The component parts were then mapped to equivalent probabilistic graphical structures such as Bayesian Belief Nets and Markov Random Fields to produce a composite chain graph that provides a probabilistic classification of risk expertise to complement the expert clinical judgements. © Springer-Verlag 2010.

Understanding data collection behaviour of mental health practitioners

Failure to detect patients at risk of attempting suicide can result in tragic consequences. Identifying risks earlier and more accurately helps prevent serious incidents occurring and is the objective of the GRiST clinical decision support system (CDSS). One of the problems it faces is high variability in the type and quantity of data submitted for patients, who are assessed in multiple contexts along the care pathway. Although GRiST identifies up to 138 patient cues to collect, only about half of them are relevant for any one patient and their roles may not be for risk evaluation but more for risk management. This paper explores the data collection behaviour of clinicians using GRiST to see whether it can elucidate which variables are important for risk evaluations and when. The GRiST CDSS is based on a cognitive model of human expertise manifested by a sophisticated hierarchical knowledge structure or tree. This structure is used by the GRiST interface to provide top-down controlled access to the patient data. Our research explores relationships between the answers given to these higher-level 'branch' questions to see whether they can help direct assessors to the most important data, depending on the patient profile and assessment context. The outcome is a model for dynamic data collection driven by the knowledge hierarchy. It has potential for improving other clinical decision support systems operating in domains with high dimensional data that are only partially collected and in a variety of combinations.

Representing human expertise by the OWL web ontology language to support knowledge engineering in decision support systems

Clinical decision support systems (CDSSs) often base their knowledge and advice on human expertise. Knowledge representation needs to be in a format that can be easily understood by human users as well as supporting ongoing knowledge engineering, including evolution and consistency of knowledge. This paper reports on the development of an ontology specification for managing knowledge engineering in a CDSS for assessing and managing risks associated with mental-health problems. The Galatean Risk and Safety Tool, GRiST, represents mental-health expertise in the form of a psychological model of classification. The hierarchical structure was directly represented in the machine using an XML document. Functionality of the model and knowledge management were controlled using attributes in the XML nodes, with an accompanying paper manual for specifying how end-user tools should behave when interfacing with the XML. This paper explains the advantages of using the web-ontology language, OWL, as the specification, details some of the issues and problems encountered in translating the psychological model to OWL, and shows how OWL benefits knowledge engineering. The conclusions are that OWL can have an important role in managing complex knowledge domains for systems based on human expertise without impeding the end-users' understanding of the knowledge base. The generic classification model underpinning GRiST makes it applicable to many decision domains and the accompanying OWL specification facilitates its implementation.

Implementing a knowledge management system within an NHS hospital:a case study exploring the roll-out of an Electronic Patient Record (EPR)

This research aims to contribute to understanding the implementation of knowledge management systems (KMS) in the field of health through a case study, leading to theory building and theory extension. We use the concept of the business process approach to knowledge management as a theoretical lens to analyse and explore how a large teaching hospital developed, executed and practically implemented a KMS. A qualitative study was conducted over a 2.5 year period with data collected from semi-structured interviews with eight members of the strategic management team, 12 clinical users and 20 patients in addition to non-participant observation of meetings and documents. The theoretical propositions strategy was used as the overarching approach for data analysis. Our case study provides evidence that true patient centred approaches to supporting care delivery with a KMS benefit from process thinking at both the planning and implementation stages, and an emphasis on the knowledge demands resulting from: the activities along the care pathways; where cross-overs in care occur; and knowledge sharing for the integration of care. The findings also suggest that despite the theoretical awareness of KMS implementation methodologies, the actual execution of such systems requires practice and learning. Flexible, fluid approaches through rehearsal are important and communications strategies should focus heavily on transparency incorporating both structured and unstructured communication methods.

Hálapénz a magyar egészségügyben = Gratitude money in the Hungarian health sector

A tanulmány szerzői lakossági és orvosi minta kikérdezése alapján arra keresik a választ, hogy a valóságban mennyire elterjedt a hálapénz adása és elfogadása a magyar egészségügyben, miként szóródik az egyes orvosi szakmák között, és mekkora az egyes beavatkozási formák hálapénzára. A kapott eredmények szerint, a hálapénzárak nyilvánossá tételének korlátai ellenére a piac szereplői többé-kevésbé egyöntetűen ítélik meg, mi mennyibe kerül. A szerzők megbecsülik az egy év leforgása alatt kifizetett hálapénz összegét. Ennek alapján arra a következtetésre jutnak, hogy az "átlagorvos" hálapénzből származó bevétele bő másfélszerese hálapénz nélkül vett jövedelmének. __________ The authors examine the incidence, in the Hungarian health sector, of gratitude payments from patients to doctors, based on a questionnaire administered to samples of the public and of the medical profession. They look at how the payments are distributed among the branches of medicine, and what payment is customary for various medical treatments. The survey findings show that although there are constraints on public knowledge of the size of gratitude payments, market actors more or less agree in their estimates of what provisions cost. Based on this, the authors conclude that the income the "average" doctor receives from gratitude payments is at least one-and-a-half times as much as his or her income apart from gratitude money.

The impact of the recession on health care expenditure — How does the Czech Republic, Hungary, Poland and Slovakia compare to other OECD countries?

In the past few years, several papers have been published in the international literature on the impact of the economic crisis on health and health care. However, there is limited knowledge on this topic regarding the Central and Eastern European (CEE) countries. The main aims of this study are to examine the effect of the financial crisis on health care spending in four CEE countries (the Czech Republic, Hungary, Poland and Slovakia) in comparison with the OECD countries. In this paper we also revised the literature for economic crisis related impact on health and health care system in these countries. OECD data released in 2012 were used to examine the differences in growth rates before and after the financial crisis. We examined the ratio of the average yearly growth rates of health expenditure expressed in USD (PPP) between 2008–2010 and 2000–2008. The classification of the OECD countries regarding “development” and “relative growth” resulted in four clusters. A large diversity of “relative growth” was observed across the countries in austerity conditions, however the changes significantly correlate with the average drop of GDP from 2008 to 2010. To conclude, it is difficult to capture visible evidence regarding the impact of the recession on the health and health care systems in the CEE countries due to the absence of the necessary data. For the same reason, governments in this region might have a limited capability to minimize the possible negative effects of the recession on health and health care systems.

Doctor-Patient Knowledge Transfer: Innovative Technologies and Policy Implications

The aim of this study was to empirically investigate the barriers in doctor-patient communication and knowledge transfer and the role of innovative technologies in overcoming these barriers. We applied qualitative research methods. Our results show that patients extensively use information sources, primarily the Internet before the visits. Patients regularly apply a self-diagnosis regarding their diseases. This implies several risks as many of them are not able to properly interpret the found information and at the same time the information might not be reliable. To overcome these risks efforts are required within the fields of technology developments for making web sites more reliable and improvement of the health culture of patients, as well. Our research identified the most significant barriers of doctor-patient communication including limited time, the patients’ distress, inadequate health culture and prior knowledge, as well as poor communication skills of some clinicians. Technology might help clinicians to use their limited time more effectively. In the long term, innovative technology solutions might take over some tasks of the health care personnel if they provide reliable health information adapted to the patient’s health, emotional and psychosocial status. Barriers of access to the new technology should be identified and addressed otherwise it would increase the already existing knowledge gap between patients and doctors.

Managerial work roles of health care executives in the changing environment of academic medical centers

The current U.S. health care system faces numerous environmental challenges. To compete and survive, health care organizations are developing strategies to lower costs and increase efficiency and quality. All of these strategies require rapid and precise decision making by top level managers. The purpose of this study is to determine the relationship between the environment, made up of unfavorable market conditions and limited resources, and the work roles of top level managers, specifically in the settings of academic medical centers. Managerial work roles are based on the ten work roles developed by Henry Mintzberg, in his book, The Nature of Managerial Work (1973). ^ This research utilized an integrated conceptual framework made up of systems theory in conjunction with role, attribution and contingency theories to illustrate that four most frequently performed Mintzberg's work roles are affected by the two environment dimensions. The study sample consisted of 108 chief executive officers in academic medical centers throughout the United States. The methods included qualitative methods in the form of key informants and case studies and quantitative in the form of a survey questionnaire. Research analysis involved descriptive statistics, reliability tests, correlation, principal component and multivariate analyses. ^ Results indicated that under the market condition of increased revenue based on capitation, the work roles increased. In addition, under the environment dimension of limited resources, the work roles increased when uncompensated care increased while Medicare and non-government funding decreased. ^ Based on these results, a typology of health care managers in academic medical centers was created. Managers could be typed as a strategy-formulator, relationship-builder or task delegator. Therefore, managers who ascertained their types would be able to use this knowledge to build their strengths and develop their weaknesses. Furthermore, organizations could use the typology to identify appropriate roles and responsibilities of managers for their specific needs. Consequently, this research is a valuable tool for understanding health care managerial behaviors that lead to improved decision making. At the same time, this could enhance satisfaction and performance and enable organizations to gain the competitive edge . ^

The knowledge and use of critical thinking teaching strategies of faculty in associate degree nursing education programs

The purpose of this study was to determine the knowledge and use of critical thinking teaching strategies by full-time and part-time faculty in Associate Degree Nursing (ADN) programs. ^ Sanders CTI (1992) instrument was adapted for this study and pilot-tested prior to the general administration to ADN faculty in Southeast Florida. This modified instrument, now termed the Burroughs Teaching Strategy Inventory (BTSI), returned reliability estimates (Cronbach alphas of .71, .74, and .82 for the three constructs) comparable to the original instrument. The BTSI was administered to 113 full-time and part-time nursing faculty in three community college nursing programs. The response rate was 92% for full-time faculty (n = 58) and 61% for part-time faculty (n = 55). ^ The majority of participants supported a combined definition of critical thinking in nursing which represented a composite of thinking skills that included reflective thinking, assessing alternative viewpoints, and the use of problem-solving. Full-time and part-time faculty used different teaching strategies. Full-time faculty most often used multiple-choice exams and lecture while part-time faculty most frequently used discussion within their classes. One possible explanation for specific strategy choices and differences might be that full-time faculty taught predominately in theory classes where certain strategies would be more appropriate and part-time faculty taught predominately clinical classes. Both faculty types selected written nursing care plans as the second most effective critical thinking strategy. ^ Faculty identified several strategies as being effective in teaching critical thinking. These strategies included discussion, case studies, higher order questioning, and concept analysis. These however, were not always the strategies that were used in either the classroom or clinical setting. ^ Based on this study, the author recommends that if the profession continues to stress critical thinking as a vital component of practice, nursing faculty should receive education in appropriate critical teaching strategies. Both in-service seminars and workshops could be used to further the knowledge and use of critical thinking strategies by faculty. Qualitative research should be done to determine why nursing faculty use self-selected teaching strategies. ^

A worksite nutrition education program increased firefighters' knowledge and resulted in healthier attitudes toward fad diets

The effectiveness of a worksite nutrition education program to improve firefighters' knowledge and weight management strategies was evaluated. One hundred fifty Miami-Dade Fire Rescue workers recruited for the study were randomly assigned to an intervention or a control group. The intervention group attended four 30-minute worksite nutrition education sessions. A nutrition knowledge test completed by both groups before and after the intervention showed no significant differences between groups for pre-intervention nutrition knowledge. The post-intervention increase in nutrition knowledge was significantly greater (p < 0.001) for the intervention group (16.8% ± 8.2) compared to the control group (4% ± 8.9). No significant pre-intervention difference was found between the groups' predilection toward a ketogenic diet. A statistically significant (p < 0.01) reduction was seen in the intervention group's willingness (0.57 ± 1.06) to use this diet compared to the control group (0.02 ± 0.99). Results indicate that worksite nutrition education can improve firefighters' knowledge and weight reduction strategies. ^

Nursing curriculum: Changing students' knowledge and biases towards older adults

Caring for the older adult is a topic debated and discussed at all levels of today's society. Nurses are expected to educate patients and family members about their medications and care following hospitalization or contact with the health care system. The majority of these patients are elderly. The purpose of the study was to determine if a course on aging would affect the knowledge and biases of nursing students in a Baccalaureate nursing program at a Southeast Florida University. Nursing students (N = 52) were surveyed at the beginning of the semester using Palmore's Facts on Aging Quiz that is structured to determine the knowledge and biases of individuals towards the older adult. Students were surveyed before and after the nursing course that had a didactic and clinical component in the hospital setting. Analysis of the data by Chi square and repeated measure ANOVA supported the hypothesis that a course segment on aging would affect the knowledge level of the nursing students and result in changes of their biases toward the older adult. ^

The knowledge and promotion of exercise to older adults with type 2 diabetes by dietitian diabetes educators

The extent to which Registered Dietitians (RD) promote exercise as part of diabetes self-management education to older diabetic adults has not been established. This study explored the exercise-related knowledge, design, and content of educational programs among RDs who were Certified Diabetes Educators (CDEs) and non-CDEs. The Exercise Teaching Questionnaire was completed by 94 CDEs and 73 non-CDEs in Florida, California, and Texas. ^ CDEs had significantly (p < 0.001) higher mean Knowledge, Design, and Content scores (11.8 ± 1.1, 33.5 ± 9.4, 26.9 ± 4.8, respectively) than non-CDEs (11.1 ± 1.6, 29.2 ± 11.1, 22.4 ± 7.4, respectively). However, Knowledge means for both CDEs and non-CDEs were above the 85 percentile. Design and content scale responses showed that while dietitians provided basic information about safety and benefits related to exercise, they frequently reported “never” or only “sometimes” making exercise recommendations. ^ Although these results suggest that RDs are knowledgeable about exercise for older adults with Type 2 diabetes, greater importance should be made on training RDs to promote exercise, perhaps with an emphasis on a comprehensive team approach. ^
