Codes of best practice in competitive markets for managers

We study firms' corporate governance in environments where possibly heterogeneous shareholders compete for possibly heterogeneous managers. A firm, formed by a shareholder and a manager, can sign either an incentive contract or a contract including a Code of Best Practice. A Code allows for a better manager's control but makes manager's decisions hard to react when market conditions change. It tends to be adopted in markets with low volatility and in low-competitive environments. The firms with the best projects tend to adopt the Code when managers are not too heterogeneous while the best managers tend to be hired through incentive contracts when the projects are similar. Although the matching between shareholders and managers is often positively assortative, the shareholders with the best projects might be willing to renounce to hire the best managers, signing contracts including Codes with lower-ability managers.

Traitement pharmacologique de la schizophrénie: évaluation comparative de la qualité des recommandations de pratique clinique [Comparative evaluation of clinical practice guidelines for the treatment of schizophrenia]

INTRODUCTION: Many clinical practice guidelines (CPG) have been published in reply to the development of the concept of "evidence-based medicine" (EBM) and as a solution to the difficulty of synthesizing and selecting relevant medical literature. Taking into account the expansion of new CPG, the question of choice arises: which CPG to consider in a given clinical situation? It is of primary importance to evaluate the quality of the CPG, but until recently, there has been no standardized tool of evaluation or comparison of the quality of the CPG. An instrument of evaluation of the quality of the CPG, called "AGREE" for appraisal of guidelines for research and evaluation was validated in 2002. AIM OF THE STUDY: The six principal CPG concerning the treatment of schizophrenia are compared with the help of the "AGREE" instrument: (1) "the Agence nationale pour le développement de l'évaluation médicale (ANDEM) recommendations"; (2) "The American Psychiatric Association (APA) practice guideline for the treatment of patients with schizophrenia"; (3) "The quick reference guide of APA practice guideline for the treatment of patients with schizophrenia"; (4) "The schizophrenia patient outcomes research team (PORT) treatment recommendations"; (5) "The Texas medication algorithm project (T-MAP)" and (6) "The expert consensus guideline for the treatment of schizophrenia". RESULTS: The results of our study were then compared with those of a similar investigation published in 2005, structured on 24 CPG tackling the treatment of schizophrenia. The "AGREE" tool was also used by two investigators in their study. In general, the scores of the two studies differed little and the two global evaluations of the CPG converged; however, each of the six CPG is perfectible. DISCUSSION: The rigour of elaboration of the six CPG was in general average. The consideration of the opinion of potential users was incomplete, and an effort made in the presentation of the recommendations would facilitate their clinical use. Moreover, there was little consideration by the authors regarding the applicability of the recommendations. CONCLUSION: Globally, two CPG are considered as strongly recommended: "the quick reference guide of the APA practice guideline for the treatment of patients with schizophrenia" and "the T-MAP".

General Practitioners' willingness to pay for continuing medical education in a fee-for-service universal coverage health care system

Background: Sponsoring of physicians meetings by life science companies has led to reduced participation fees but might influence physician's prescription practices. A ban on such sponsoring may increase participation fees. We aimed to evaluate factors associated with physicians' willingness to pay for medical meetings, their position on the sponsoring of medical meetings and their opinion on alternative financing options. Methods: An anonymous web-based questionnaire was sent to 447 general practitioners in one state in Switzerland, identified through their affiliation to a medical association. The questionnaire evaluated physicians' willingness to pay for medical meetings, their perception of a bias in prescription practices induced by commercial support, their opinion on the introduction of a binding legislation and alternative financing options, their frequency of exchange with sales representatives and other relevant socioeconomic factors. We built a multivariate predictor logistic regression model to identify determinants of willingness to pay. Results: Of the 115 physicians who responded (response rate 26%), 48% were willing to pay more than what they currently pay for congresses, 79% disagreed that commercial support introduced a bias in their prescription practices and 61% disagreed that it introduced a bias in their colleagues' prescription practices. Based on the multivariate logistic regression, perception of a bias in peers prescription practices (OR=7.47, 95% CI 1.65-38.18) and group practice structure (OR=4.62, 95% CI 1.34-22.29) were significantly associated with an increase in willingness to pay. Two thirds (76%) of physicians did not support the introduction of a binding legislation and 53% were in favour of creating a general fund administered by an independent body. Conclusion: Our results suggest that almost half of physicians surveyed are willing to pay more than what they currently pay for congresses. Predictors of an increase in physicians' willingness to pay were perception of the influence of bias in peers prescription practices and group practice structure. Most responders did not agree that sponsoring introduced prescribing bias nor did they support the 2 introduction of a binding legislation prohibiting sponsoring but a majority did agree to an independent body that would centrally administer a general fund.

Current Molecular Imaging of Spinal Tumors in Clinical Practice.

Energy metabolism measurements in spinal cord tumors, as well as in osseous spinal tumors/metastasis in vivo, are rarely performed only with molecular imaging (MI) by positron emission tomography (PET). This imaging modality developed from a small number of basic clinical science investigations followed by subsequent work that influenced and enhanced the research of others. Apart from precise anatomical localization by coregistration of morphological imaging and quantification, the most intriguing advantage of this imaging is the opportunity to investigate the time course (dynamics) of disease-specific molecular events in the intact organism. Most importantly, MI represents one of the key technologies in translational molecular neuroscience research, helping to develop experimental protocols that may later be applied to human patients. PET may help monitor a patient at the vertebral level after surgery and during adjuvant treatment for recurrent or progressive disease. Common clinical indications for MI of primary or secondary CNS spinal tumors are: (i) tumor diagnosis, (ii) identification of the metabolically active tumor compartments (differentiation of viable tumor tissue from necrosis) and (iii) prediction of treatment response by measurement of tumor perfusion or ischemia. While spinal PET has been used under specific circumstances, a question remains as to whether the magnitude of biochemical alterations observed by MI in CNS tumors in general (specifically spinal tumors) can reveal any prognostic value with respect to survival. MI may be able to better identify early disease and to differentiate benign from malignant lesions than more traditional methods. Moreover, an adequate identification of treatment effectiveness may influence patient management. MI probes could be developed to image the function of targets without disturbing them or as treatment to modify the target's function. MI therefore closes the gap between in vitro and in vivo integrative biology of disease. At the spinal level, MI may help to detect progression or recurrence of metastatic disease after surgical treatment. In cases of nonsurgical treatments such as chemo-, hormone- or radiotherapy, it may better assess biological efficiency than conventional imaging modalities coupled with blood tumor markers. In fact, PET provides a unique possibility to correlate topography and specific metabolic activity, but it requires additional clinical and experimental experience and research to find new indications for primary or secondary spinal tumors.

Weekly sport practice and adolescent well-being.

OBJECTIVE: Sport practice is widely encouraged, both in guidelines and in clinical practice, because of its broad range of positive effects on health. However, very limited evidence directly supports this statement among adolescents and the sport duration that we should recommend remains unknown. We aimed to determine sport durations that were associated with poor well-being. METHODS: We conducted a survey including 1245 adolescents (16-20 years) from the general Swiss population. Participants were recruited from various settings (sport centres, peers of sport practicing adolescents, websites) and asked to complete a web-based questionnaire. Weekly sport practice was categorised into four groups: low (0-3.5 h), average (≈ recommended 7 h (3.6-10.5)), high (≈14 h (10.6-17.5)) and very high (>17.5 h). We assessed well-being using the WHO-5 Well-Being Index. RESULTS: Compared with adolescents in the average group, those in the very high group had a higher risk of poor well-being (OR 2.29 (95% CI 1.11 to 4.72)), as did those in the low group (OR 2.33 (1.58 to 3.44)). In contrast, those in the high group had a lower risk of poor well-being than those in the average group (OR 0.46 (0.23 to 0.93)). CONCLUSIONS: We found an inverted, U-shaped relationship between weekly sport practice duration and well-being among adolescents. The peak scores of well-being were around 14 h per week of sport practice, corresponding to twice the recommended 7 h. Practicing higher sport durations was an independent risk factor of poor well-being.

Major depressive disorders in the general hospital: how to implement guidelines.

OBJECTIVE: An implementation study that evaluated the impact of previously adopted guidelines on the clinical practice of medical residents was conducted to improve the recognition and treatment of major depressive disorders (MDDs) in hospitalized patients with somatic diseases. METHODS: Guidelines were implemented in two wards (ENT and oncology) using intranet diffusion, interactive sessions with medical residents, and support material. Discharge letters of 337 and 325 patients, before and after the intervention, respectively, were checked for statement of diagnosis or treatment of MDDs and, in a post hoc analysis, for any mention about psychiatric management. RESULTS: No difference was found in the number of diagnosed or treated MDDs before and after the intervention. However, significantly more statements about psychological status (29/309 vs. 13/327) and its management (36/309 vs. 19/327) were observed after the intervention (P<.01). CONCLUSION: The intervention was not successful in improving the management of MDDs. However, a possible effect on general psychological aspects of medical diseases was observed.

Code of Practice on Fluoridation of Drinking Water 2007 Fluoridation of drinking water, the main aim of which is the prevention and control of dental caries (dental decay), commenced in Ireland in 1964 after the introduction of the Health (Fluoridation of Water Supplies) Act 1960. The Act provides that health authorities shall arrange for the fluoridation of public piped water supplies. The Act also provides that sanitary (local) authorities may act as the agents of health authorities in fluoridating public piped water supplies. Currently approximately 73% of the population receives fluoridated water from public water supplies. Click here to download PDF 195kb

A Study to Examine the Attitudes of General Practitioners Towards Drug Users in the North East Region of Ireland

The research examines general practitioners attitudes and how these effect the management of drug misusers within their practice. The methodology is quantitative in approach. The instrument used is a structured postal questionnaire. Participants include all general practitioners within the North East region of Ireland. Anonymity and confidentiality of all respondents are guaranteed. Data was collected over a six week period, under the following headings - attitudes and beliefs, factors influencing treatment, treatment options, training and demographics. Attitudes and beliefs towards drug users were measured using a five point Likert scale ranging from strongly agrees to strongly disagree. The data was analysed with the aid of a computer package, SPSS allowing descriptive statistics to be presented. Results indicate that the majority of respondents are male. There appears to be sympathy towards drug users and that treatment approaches should be holistic. However, there appears to be a major lack of confidence in treating and managing drug misusers. Patient, social and practice factors all influence the decision to the drug misuser. Treatment options are varied, ranging from methadone maintenance to referral for residential treatment. However, a number of respondents offer no treatment for drug misusers. General practitioners do not feel adequately trained in treating and/or managing this client group. Results indicate that improved communication, ongoing education and more research is needed in this area.This resource was contributed by The National Documentation Centre on Drug Use.

Accident & Emergency Nursing Assessment of Deliberate Self Harm. Exploring the Impact of Introducing a Suicide Education Programme and a Suicide Intent Scale into A&E/MAU Nursing Practice: A Pilot Study

A proposal to pilot nursing assessment of self harm in Accident and Emergency Departments (A&E) was developed by key stakeholders in nurse education and suicide prevention in the South East and submitted to the National Council for the Professional Development of Nursing and Midwifery in April 2002.The proposal included the introduction of a suicide intent scale. Following an initial training programme, a suicide intent scale was utilised by nursing staff in A&E and the Medical Assessment Unit (MAU),Wexford General Hospital and evaluated over a period of nine months. Four months into the study the National Suicide Research Foundation (NSRF) was invited to collaboratively prepare a successful submission to the Health Research Board (HRB) as part of ‘Building Partnerships for a Healthier Future Research Awards 2004’. The NSRF undertook independent scientific evaluation of the outcomes of the suicide awareness programme. The study is in line with priorities determined by Reach Out, the National Strategy for Action on Suicide Prevention 2005-2014 (HSE, 2005) and the HSE-South East Suicide Prevention Programme through raising nursing staff awareness of the public health issue of suicide/deliberate self harm and by improving the efficiency and quality of nursing services offered to persons who present to acute hospitals with deliberate self harm. The study findings indicate evidence to positively support nursing assessment of DSH using a suicide intent scale in terms of assessing behavioural characteristics of individual clients and their suicide risk. Enhanced confidence levels of nursing personnel in caring for suicidal clients was demonstrated by staff who participated in an education programme related to risk assessment and specifically the use of a suicide intent scale.This resource was contributed by The National Documentation Centre on Drug Use.

Prevalence, awareness, treatment and control of high blood pressure in a Swiss city general population: the CoLaus study.

BACKGROUND: This study is aimed to assess the prevalence of awareness, treatment and control of high blood pressure (HBP) and associated factors in a Swiss city. DESIGN: Population-based cross-sectional study of 6182 participants (52.5% women) aged 35-75 years living in Lausanne, Switzerland. METHODS: HBP was defined as blood pressure >/=140/90 mmHg or current antihypertensive medication. RESULTS: The overall prevalence of HBP was 36% (95% confidence interval: 35-38%). Among participants with HBP, 63% were aware of it. Among participants aware of HBP, 78% were treated, and among those treated, 48% were controlled (BP <140/90 mmHg). In multivariate analysis, HBP prevalence was associated with older age, male sex, low educational level, high alcohol intake, awareness of diabetes or dyslipidaemia, obesity and parental history of myocardial infarction. HBP awareness was associated with older age, female sex, awareness of diabetes or dyslipidaemia, obesity and parental history of myocardial infarction. HBP control was associated with younger age, higher educational level and no alcohol intake. Alone or in combination, sartans were the most often prescribed antihypertensive medication category (41%), followed by diuretics, beta-blockers, angiotensin converting enzyme inhibitors and calcium channel blockers. Only 31% of participants treated for HBP were taking >/=2 antihypertensive medications. CONCLUSION: Although more than half of all participants with HBP were aware and more than three-quarters of them received a pharmacological treatment, less than half of those treated were adequately controlled.

Assessment of drug-induced hepatotoxicity in clinical practice: a challenge for gastroenterologists.

Currently, pharmaceutical preparations are serious contributors to liver disease; hepatotoxicity ranking as the most frequent cause for acute liver failure and post-commercialization regulatory decisions. The diagnosis of hepatotoxicity remains a difficult task because of the lack of reliable markers for use in general clinical practice. To incriminate any given drug in an episode of liver dysfunction is a step-by-step process that requires a high degree of suspicion, compatible chronology, awareness of the drug's hepatotoxic potential, the exclusion of alternative causes of liver damage and the ability to detect the presence of subtle data that favors a toxic etiology. This process is time-consuming and the final result is frequently inaccurate. Diagnostic algorithms may add consistency to the diagnostic process by translating the suspicion into a quantitative score. Such scales are useful since they provide a framework that emphasizes the features that merit attention in cases of suspected hepatic adverse reaction as well. Current efforts in collecting bona fide cases of drug-induced hepatotoxicity will make refinements of existing scales feasible. It is now relatively easy to accommodate relevant data within the scoring system and to delete low-impact items. Efforts should also be directed toward the development of an abridged instrument for use in evaluating suspected drug-induced hepatotoxicity at the very beginning of the diagnosis and treatment process when clinical decisions need to be made. The instrument chosen would enable a confident diagnosis to be made on admission of the patient and treatment to be fine-tuned as further information is collected.
