    Just how difficult can it be counting up R&D funding for emerging technologies (and is tech mining with proxy measures going to be any better?)

    Decision makers considering policy or strategy related to the development of emerging technologies expect high quality data on the support for different technological options. A natural starting point would be R&D funding statistics. This paper explores the limitations of such aggregated data in relation to the substance and quantification of funding for emerging technologies. Using biotechnology as an illustrative case, we test the utility of a novel taxonomy to demonstrate the endemic weaknesses in the availability and quality of data from public and private sources. Using the same taxonomy, we consider the extent to which tech-mining presents an alternative, or potentially complementary, way to determine support for emerging technologies using proxy measures such as patents and scientific publications

    Conceptual graph-based knowledge representation for supporting reasoning in African traditional medicine

    Get PDF
    Although African patients use both conventional or modern and traditional healthcare simultaneously, it has been proven that 80% of people rely on African traditional medicine (ATM). ATM includes medical activities stemming from practices, customs and traditions which were integral to the distinctive African cultures. It is based mainly on the oral transfer of knowledge, with the risk of losing critical knowledge. Moreover, practices differ according to the regions and the availability of medicinal plants. Therefore, it is necessary to compile tacit, disseminated and complex knowledge from various Tradi-Practitioners (TP) in order to determine interesting patterns for treating a given disease. Knowledge engineering methods for traditional medicine are useful to model suitably complex information needs, formalize knowledge of domain experts and highlight the effective practices for their integration to conventional medicine. The work described in this paper presents an approach which addresses two issues. First it aims at proposing a formal representation model of ATM knowledge and practices to facilitate their sharing and reusing. Then, it aims at providing a visual reasoning mechanism for selecting best available procedures and medicinal plants to treat diseases. The approach is based on the use of the Delphi method for capturing knowledge from various experts which necessitate reaching a consensus. Conceptual graph formalism is used to model ATM knowledge with visual reasoning capabilities and processes. The nested conceptual graphs are used to visually express the semantic meaning of Computational Tree Logic (CTL) constructs that are useful for formal specification of temporal properties of ATM domain knowledge. Our approach presents the advantage of mitigating knowledge loss with conceptual development assistance to improve the quality of ATM care (medical diagnosis and therapeutics), but also patient safety (drug monitoring)

    Quality of medication use in primary care - mapping the problem, working to a solution: a systematic review of the literature

    Get PDF
    Background: The UK, USA and the World Health Organization have identified improved patient safety in healthcare as a priority. Medication error has been identified as one of the most frequent forms of medical error and is associated with significant medical harm. Errors are the result of the systems that produce them. In industrial settings, a range of systematic techniques have been designed to reduce error and waste. The first stage of these processes is to map out the whole system and its reliability at each stage. However, to date, studies of medication error and solutions have concentrated on individual parts of the whole system. In this paper we wished to conduct a systematic review of the literature, in order to map out the medication system with its associated errors and failures in quality, to assess the strength of the evidence and to use approaches from quality management to identify ways in which the system could be made safer. Methods: We mapped out the medicines management system in primary care in the UK. We conducted a systematic literature review in order to refine our map of the system and to establish the quality of the research and reliability of the system. Results: The map demonstrated that the proportion of errors in the management system for medicines in primary care is very high. Several stages of the process had error rates of 50% or more: repeat prescribing reviews, interface prescribing and communication and patient adherence. When including the efficacy of the medicine in the system, the available evidence suggested that only between 4% and 21% of patients achieved the optimum benefit from their medication. Whilst there were some limitations in the evidence base, including the error rate measurement and the sampling strategies employed, there was sufficient information to indicate the ways in which the system could be improved, using management approaches. The first step to improving the overall quality would be routine monitoring of adherence, clinical effectiveness and hospital admissions. Conclusion: By adopting the whole system approach from a management perspective we have found where failures in quality occur in medication use in primary care in the UK, and where weaknesses occur in the associated evidence base. Quality management approaches have allowed us to develop a coherent change and research agenda in order to tackle these, so far, fairly intractable problems

    Estimates of patient costs related with population morbidity: Can indirect costs affect the results?

    Get PDF
    A number of health economics works require patient cost estimates as a basic information input. However the accuracy of cost estimates remains in general unspecified. We propose to investigate how the allocation of indirect costs or overheads can affect the estimation of patient costs in order to allow for improvements in the analysis of patient costs estimates. Instead of focusing on the costing method, this paper proposes to highlight changes in variance explained observed when a methodology is chosen. We compare three overhead allocation methods for a specific Spanish population adjusted using the Clinical Risk Groups (CRG), and we obtain different series of full-cost group estimates. As a result, there are significant gains in the proportion of the variance explained, depending upon the methodology used. Furthermore, we find that the global amount of variation explained by risk adjustment models depends mainly on direct costs and is independent of the level of aggregation used in the classification system.Patient costs, Clinical Risk Groups, Variation explained, Overhead allocation

    Internet addiction: a systematic review of epidemiological research for the last decade

    Get PDF
    In the last decade, Internet usage has grown tremendously on a global scale. The increasing popularity and frequency of Internet use has led to an increasing number of reports highlighting the potential negative consequences of overuse. Over the last decade, research into Internet addiction has proliferated. This paper reviews the existing 68 epidemiological studies of Internet addiction that (i) contain quantitative empirical data, (ii) have been published after 2000, (iii) include an analysis relating to Internet addiction, (iv) include a minimum of 1000 participants, and (v) provide a full-text article published in English using the database Web of Science. Assessment tools and conceptualisations, prevalence, and associated factors in adolescents and adults are scrutinised. The results reveal the following. First, no gold standard of Internet addiction classification exists as 21 different assessment instruments have been identified. They adopt official criteria for substance use disorders or pathological gambling, no or few criteria relevant for an addiction diagnosis, time spent online, or resulting problems. Second, reported prevalence rates differ as a consequence of different assessment tools and cut-offs, ranging from 0.8% in Italy to 26.7% in Hong Kong. Third, Internet addiction is associated with a number of sociodemographic, Internet use, and psychosocial factors, as well as comorbid symptoms and disorder in adolescents and adults. The results indicate that a number of core symptoms (i.e., compulsive use, negative outcomes and salience) appear relevant for diagnosis, which assimilates Internet addiction and other addictive disorders and also differentiates them, implying a conceptualisation as syndrome with similar etiology and components, but different expressions of addictions. Limitations include the exclusion of studies with smaller sample sizes and studies focusing on specific online behaviours. Conclusively, there is a need for nosological precision so that ultimately those in need can be helped by translating the scientific evidence established in the context of Internet addiction into actual clinical practice

    Systematic review of the safety of medication use in inpatient, outpatient and primary care settings in the Gulf Cooperation Council countries

    Background Errors in medication use are a patient safety concern globally, with different regions reporting differing error rates, causes of errors and proposed solutions. The objectives of this review were to identify, summarise, review and evaluate published studies on medication errors, drug related problems and adverse drug events in the Gulf Cooperation Council (GCC) countries. Methods A systematic review was carried out using six databases, searching for literature published between January 1990 and August 2016. Research articles focussing on medication errors, drug related problems or adverse drug events within different healthcare settings in the GCC were included. Results Of 2094 records screened, 54 studies met our inclusion criteria. Kuwait was the only GCC country with no studies included. Prescribing errors were reported to be as high as 91% of a sample of primary care prescriptions analysed in one study. Of drug-related admissions evaluated in the emergency department the most common reason was patient non-compliance. In the inpatient care setting, a study of review of patient charts and medication orders identified prescribing errors in 7% of medication orders, another reported prescribing errors present in 56% of medication orders. The majority of drug related problems identified in inpatient paediatric wards were judged to be preventable. Adverse drug events were reported to occur in 8.5–16.9 per 100 admissions with up to 30% judged preventable, with occurrence being highest in the intensive care unit. Dosing errors were common in inpatient, outpatient and primary care settings. Omission of the administered dose as well as omission of prescribed medication at medication reconciliation were common. Studies of pharmacists’ interventions in clinical practice reported a varying level of acceptance, ranging from 53% to 98% of pharmacists’ recommendations. Conclusions Studies of medication errors, drug related problems and adverse drug events are increasing in the GCC. However, variation in methods, definitions and denominators preclude calculation of an overall error rate. Research with more robust methodologies and longer follow up periods is now required.Peer reviewe

    The Sources of Quality in the Pharmaceutical Industry

    Get PDF
    This paper analyzes the sources of quality of a pharmaceutical product. After identifying eight quality dimensions, a framework of hypothetical sources that contribute the most to shape those dimensions is established. The framework, based on Garvin’s pioneering work, is applied to case studies of laboratories operating in Argentina. Framework relevance is considered using correlation analysis. Laboratories are ranked through expert opinion by the quality of its products using the eight dimensions mentioned above; it is observed that there is no perfect parallelism in ranking along all dimensions, possibly revealing different managerial priorities and uses of resources among laboratories, as well as different sources of quality and different business strategies. Correlation analysis also suggests that the study of a pharmaceutical product is a complex task when a modern concept of quality is considered. Once the existence of different quality dimensions is accepted, the following two questions are investigated: (1) Are there specific sources of quality that support some dimensions (and not others) and that are based on identifiable organizational aspects or specific technologies? (2) What are the generic sources of quality (affecting all dimensions) and in what way do they contribute to improve performance or highlight quality dimensions? It is assumed as a starting point that among the sources of quality there are generic sources, affecting all dimensions, and specific sources, which affect only some dimensions. In concrete cases, specific quality sources are identified, although the search for specific quality sources for each dimension is not conclusive. The study of generic quality sources, however, suggests that corporate systems, corporate culture, and management policies contribute to incorporate quality in a product. Thus quality results from the interaction between generic and specific sources. In the final part of the paper, recommendations for academics and industrialists are provided, as well as some conclusions.Pharmaceutical product, Garvin’s quality dimensions, quality sources, pharmaceutical laboratories in Argentina, corporate systems, corporate culture.

    Consideration of the novel psychoactive substances (‘legal highs’)

    Get PDF
    Original report can be found at: http://www.homeoffice.gov.uk/ Crown Copyright, the Advisory Council/ The Home Office. This work is published under an open government license.The Advisory Council on the Misuse of Drugs (ACMD) committed to providing the Government with advice on novel psychoactive substances (often colloquially termed „legal highs‟). This is a relatively recent phenomenon, exemplified by the drug known as mephedrone. The actions by the ACMD and subsequently by the Government on this drug have gone some way to reducing the potential harms caused by this substance. However, there is more that can be done. The advent of novel psychoactive substances has changed the face of the drug scene remarkably and with rapidity. The range of substances now available, their lack of consistency and the potential harms users are exposed to are now complex and multi-faceted. In light of this we have pleasure in enclosing the Council‟s report. This report provides advice on high level issues that ACMD believe the Government should give careful consideration to in addressing legally available psychoactive substances. The report does not purport to provide a single solution to the problem, but rather a number of practicable options that, in combination, seek to tackle the on-going sale, supply and consequential harms. It is important that the Government recognises that each and every department, that has a locus of responsibility in drug issues should both take personal ownership and share collective responsibility of the recommendations in this report. Tackling the issues that are raised by novel psychoactive substances requires a co-ordination of efforts that can only be realised by a strategic and co-operative approach. The ACMD has identified lead departments for each of the recommendations that should assist and guide the Government in this aim. The ACMD provides key recommendations in this report on legislation, public health, education and research. The key legislative measures are primarily concerned with tightening the enforcement of existing legislation and moving the responsibility for the supply of novel psychoactive substances to the vendors, such that the burden of proof falls to them. The ACMD believe it is for vendors to prove that such substances are neither analogues of current medicines nor products harmful to consumers in their intended form. The ACMD also makes key recommendations around public awareness from local to international initiatives.Final Published versio

    Handbuch Kommunikationsstrategien zur SchÀrfung des Umweltbewusstseins im Umgang mit Arzneimitteln : Forschungsvorhaben 37 08 61 400 des Umweltbundesamtes

    Get PDF
    In Germany, as in almost all industrial countries, active pharmaceutical substances can now be found in virtually all water bodies and occasionally also in drinking water. Even though the concentrations in question tend to be very low, there are initial signs of their impact on aquatic life. There is no evidence as yet of any acute consequences for human health. It is, however, impossible to rule out long-term consequences from these minimal concentrations or unexpected effects from the interaction between various active ingredients (cocktail effect). At special risk here are sensitive segments of the population such as children and the chronically ill. There is thus a need for action on precautionary grounds. The main actors in the health system are largely unaware of the problem posed by drug residues in water. Although knowledge cannot be equated with awareness – given the existence of the ‘not wanting to know' phenomenon – the first step is to generate a consolidated knowledge base. Only by creating awareness of the problem can further strategies be implemented to ultimately enlighten and bring about behavioural change. At stake here is the overall everyday handling of medications, including prescription, compliance, and drug-free disease prevention down to the doctor-patient relationship. The latter, namely, is often characterised by misunderstandings and a lack of communication about the – supposed – need to prescribe drugs. The first part of the strategy for the general public involves using various channels and media to address three different target groups. These were identified by ISOE in an empirical survey as reacting differently to the problem under review: · ‘The Deniers/Relativists' · ‘The Truth-Seekers' · ‘The Hypersensitives' The intention is to address each target group in the right tone and using the most suitable line of reasoning via specific media and with the proper degree of differentiation. The ‘Truth-Seekers' play an opinion-leading role here. They can be provided with highly differentiated information through sophisticated media which they then pass on to their dialogue partners in an appropriate form. The second part of the strategy for the general public relates to the communication of proper disposal routes for expired drugs. The goal is to confine disposal to pharmacies so that on no account are they flushed down the sink or toilet. Based on an analysis of typical errors in existing communications media on this topic, ISOE prepared recommendations for drafting proper information materials. In addressing pharmacists, the first priority is to convey hard facts: to this end we propose a PR campaign to place articles in the main specialist media. At the same time, the subject should feature in training and continuing education programmes. Another aim is to strengthen the advisory function of the pharmacies. The environmentally sensitive target group would indeed react positively to having their attention drawn to the issue of drug residues in water. For all other customers, the pharmacists can and should act as consultants: they emphasise how important it is to take medication as instructed (compliance) and use suitable pack sizes, and warn older customers in particular about the potential hazards of improper drug intake. The first stage of the communications strategy for doctors likewise revolves around knowledge. Here, however, it is important to take into account their self-image as scientists while in fact having little grasp of this specific area. The line to take is that of ‘discursive selfenlightenment'. This means that the issue of drug residues in water cannot be conveyed to doctors by laymen but must be taken up and imparted via the major media of the medical profession and by medical association officials (top-down). The second stage, namely that of raising doctors’ awareness of the problem, is likely to encounter strong resistance from some of the medical profession. They may fear a threat of interference in treatment plans from an environmental perspective and feel the need to emphasise that doctors are not responsible for environmental issues. As shown in empirical surveys by ISOE, such a defensive reaction is ultimately down to an underlying taboo: people are loath to discuss the over-prescription taking place in countless doctors' surgeries. And it is a fact that this problem cannot be tackled from the environmental perspective, although the goals of water protection are indeed consistent with the economic objectives of restraint in the deployment of drugs. Any communications measure for this target group has to bear in mind that doctors feel restricted by what they see as a ‘perpetual health reform' no matter which government is in power. On no account are they prepared to tolerate any new form of regulation, in this case for environmental reasons. An entirely different view of the problem is taken by ‘critical doctors' such as specialists in environmental health and those with a naturopathic focus. They are interested in the problem because they see a connection between the quality of our environment and our health. What is more, they have patients keen to be prescribed as few drugs as possible and who are instead interested in ‘talking medicine'. So, any communication strategy intent on tackling the difficult problem of oversubscribing drugs needs to look carefully at the experiences of these medical professionals and also at a ‘bottom-up strategy'. Implementation of strategic communications should be entrusted to an agency with experience in ‘issue management'. Knowledge of social marketing and the influencing of behaviour are further prerequisites. All important decisions should be taken by a consensus committee (‘MeriWa'1 round table), in which the medical profession, pharmacists and consumers are represented.In Deutschland und in fast allen IndustrielĂ€ndern finden sich mittlerweile Medikamentenwirkstoffe in nahezu allen GewĂ€ssern und vereinzelt auch im Trinkwasser. Auch wenn die Konzentrationen in der Regel sehr gering sind, lassen sich erste Anzeichen fĂŒr Auswirkungen auf Wasserlebewesen nachweisen. Akute Folgen fĂŒr die menschliche Gesundheit sind bisher nicht erwiesen. Es kann allerdings nicht ausgeschlossen werden, dass sich Langzeitfolgen dieser Niedrigstkonzentrationen entwickeln und unerwartete Effekte durch die Wechselwirkung zwischen verschiedenen Wirkstoffen (Cocktaileffekt) entstehen. Besonders gefĂ€hrdet sind dabei sensible Bevölkerungsgruppen wie Kinder und chronisch Kranke. Es besteht daher nicht zuletzt aus VorsorgegrĂŒnden Handlungsbedarf. Das Problem der Medikamentenreste im Wasser ist bei den wichtigsten Akteuren des Gesundheitssystems weitgehend unbekannt. Auch wenn Wissen nicht mit Bewusstsein gleichgesetzt werden kann – denn es gibt auch das PhĂ€nomen des Nicht-Wissen-Wollens – geht es in einem ersten Schritt darum, fundiertes Wissen zu erzeugen. Nur auf Basis dieser Sensibilisierung können weitere Strategien umgesetzt und letztendlich AufklĂ€rung und VerhaltensĂ€nderungen erreicht werden. Dabei geht es um die gesamte Alltagspraxis im Umgang mit Medikamenten. Diese umfasst Fragen der Verschreibung, der Compliance, der nichtmedikamentösen Krankheitsvorsorge bis hin zum Arzt-Patienten-VerhĂ€ltnis. Das ist nĂ€mlich hĂ€ufig von MissverstĂ€ndnissen und mangelnder Kommunikation ĂŒber – vermeintliche – Verschreibungsnotwendigkeiten geprĂ€gt. Der erste Teil der Strategie fĂŒr die Bevölkerung soll ĂŒber unterschiedliche KanĂ€le und Medien drei unterschiedliche Zielgruppen ansprechen, die in einer empirischen Untersuchung vom ISOE identifiziert wurden und auf das angesprochene Problem ganz unterschiedlich reagieren: · ‚Die Verleugner/Relativierer‘ · ‚Die AufklĂ€rungsinteressierten‘ · ‚Die Hypersensiblen‘ Jede Zielgruppe soll in der passenden sprachlichen und argumentativen Art und Weise durch spezifische Medien und mit dem richtigen Grad der Differenziertheit angesprochen werden. Dabei spielen „die AufklĂ€rungsinteressierten“ eine Opinionleader-Rolle. Sie können ĂŒber anspruchsvolle Medien mit sehr differenzierten Informationen versorgt werden und geben dieses Wissen dann in angemessener Form an ihre GesprĂ€chspartner weiter. Der zweite Teil der Strategie fĂŒr die Bevölkerung bezieht sich auf die Kommunikation richtiger Entsorgungswege fĂŒr Altmedikamente. Ziel ist es, dass Medikamentenreste nur noch in der Apotheke, keinesfalls aber in der SpĂŒle oder in der Toilette entsorgt werden. Auf Grundlage einer Analyse typischer Fehler in bereits bestehenden Kommunikationsmedien zu diesem Thema hat das ISOE Empfehlungen zur richtigen Konzeption von Infomaterialien erarbeitet. Bei der Ansprache der Apotheker geht es in einem ersten Schritt um die Vermittlung von Faktenwissen: Wir schlagen dazu eine PR-Kampagne vor, die Artikel in den wichtigsten Fachmedien platziert. Gleichzeitig soll das Thema auch Teil der Aus- und Fortbildung werden. ZusĂ€tzlich soll die Beraterfunktion der Apotheken gestĂ€rkt werden. Die spezielle Zielgruppe der umweltsensiblen Kunden wĂŒrde durchaus positiv darauf reagieren, wenn sie auf die Problematik der Medikamentenreste im Wasser hingewiesen wĂŒrde. Bei allen anderen Kunden können und sollen die Apotheker ihre Rolle als Berater wahrnehmen: Sie betonen, wie wichtig die korrekte Einnahme (Compliance) und adĂ€quate PackungsgrĂ¶ĂŸen sind und warnen ihre Kunden, insbesondere die Ă€lteren, auch vor potenziellen Fehleinnahmen. Bei der Kommunikationsstrategie fĂŒr Ärzte geht es im ersten Schritt ebenfalls um Wissen. Dabei muss aber deren SelbstverstĂ€ndnis als Wissenschaftler bei gleichzeitig niedrigem Wissensstand in diesem speziellen Feld berĂŒcksichtigt werden. Hier muss der Weg einer ‚diskursiven SelbstaufklĂ€rung‘ beschritten werden. Das Thema Medikamentenreste im Wasser kann somit nicht von Laien von außen an die Ärzte herangetragen werden, sondern muss in wichtigen Medien der Ärzteschaft und durch VerbandsfunktionĂ€re angenommen und kommuniziert werden (top-down). Wenn es im zweiten Schritt um eine Problemsensibilisierung geht, muss mit starkem Widerstand eines Teils der Ärzteschaft gerechnet werden. Sie könnten fĂŒrchten, dass eine Einmischung in HeilungsplĂ€ne aus Umweltsicht droht und betonen, dass Ärzte nicht fĂŒr Umweltfragen zustĂ€ndig seien. Letztlich steht – das haben empirische Untersuchungen des ISOE gezeigt – hinter dieser Problemabwehr ein Tabu: Es soll nicht darĂŒber gesprochen werden, dass in zahlreichen Praxen zu viel verschrieben wird. Diese Problematik kann tatsĂ€chlich nicht aus der Umweltperspektive angegangen werden. Doch decken sich hier die Ziele des GewĂ€sserschutzes mit den ökonomischen Zielen eines sparsamen Umgangs mit Arzneimitteln. Bei jeder Kommunikationsmaßnahme fĂŒr diese Zielgruppe muss berĂŒcksichtigt werden, dass sich die Ärzte von dem, was sie als ‚Dauergesundheitsreform‘ aller Regierungen wahrnehmen, gegĂ€ngelt fĂŒhlen. Sie sind keinesfalls bereit, eine neue Form der Regulierung, diesmal aus UmweltgrĂŒnden, hinzunehmen. Ganz anders wird das Problem von ‚kritischen Ärzten‘ wie Umweltmedizinern und von Ärzten mit Naturheilschwerpunkt gesehen. Sie interessieren sich fĂŒr die Problematik, weil sie einen Zusammenhang zwischen UmweltqualitĂ€t und Gesundheit sehen. Außerdem haben sie Patienten, die an möglichst wenig Medikamentenverschreibungen, dafĂŒr aber an einer ‚sprechenden Medizin‘ interessiert sind. Wenn eine Kommunikationsstrategie also auch das schwierige Problem der ĂŒbermĂ€ĂŸigen Verschreibungen angehen will, empfiehlt es sich, die Erfahrungen dieser Mediziner einzubeziehen und zusĂ€tzlich auf eine ‚Bottom-up-Strategie‘ abzuzielen. Mit der Umsetzung der strategischen Kommunikation sollte eine Agentur beauftragt werden, die Erfahrungen im ‚Issue Management‘ vorweisen kann. Weiterhin sollte die Agentur Kenntnisse im Social Marketing und der Beeinflussung von Verhalten haben. Alle wichtigen Entscheidungen sollten von einem Konsens-Gremium (Runder Tisch ‚MeriWa‘1) verabschiedet werden, in dem die Ärzteschaft, die Apotheker sowie die Verbraucherinnen und Verbraucher angemessen reprĂ€sentiert sind
