    The authors closely analyze a case in which a Peer Review Organization cited a physician for treatment with potential for significant adverse effect. They also critique the regulatory scheme under which peer review occurs and conclude that such regulation interferes with physicians\u27 primary obligations, fails to encourage cost-effective behavior and may decrease the quality of medical care

    SOME ASPECTS OF PAYMENT BY NEGOTIABLE INSTRUMENT: A COMPARATIVE STUDY

    Get PDF
    The scenes are laid in London, New York, Berlin, and Paris. The plot begins with a debtor\u27s giving his creditor a negotiable instrument in payment of the debt. Complications are introduced when the creditor fails to perfect his rights on the instrument, and yet, naturally enough, wishes to collect his debt. Initially both debtor and creditor are satisfied when the negotiable instrument is given in payment. If it is a time instrument, the debtor has obtained an extension of credit. The creditor, on the other hand, has placed his claim in liquid form; he may realize upon it by discounting the instrument. The Anglo-American, German, and French legal systems, in their own way, attempt to safeguard both the interests of the debtor and the creditor

    Background:New York City (NYC) remains an epicenter of the HIV epidemic in the United States. Given the variety of evidence-based HIV prevention strategies available and the significant resources required to implement each of them, comparative studies are needed to identify how to maximize the number of HIV cases prevented most economically.Methods:A new model of HIV disease transmission was developed integrating information from a previously validated micro-simulation HIV disease progression model. Specification and parameterization of the model and its inputs, including the intervention portfolio, intervention effects and costs were conducted through a collaborative process between the academic modeling team and the NYC Department of Health and Mental Hygiene. The model projects the impact of different prevention strategies, or portfolios of prevention strategies, on the HIV epidemic in NYC.Results:Ten unique interventions were able to provide a prevention benefit at an annual program cost of less than 360,000,thethresholdforconsiderationasacostsavingintervention(becauseofoffsetsbyfutureHIVtreatmentcostsaverted).Anoptimizedportfolioofthesespecificinterventionscouldresultinuptoa34360,000, the threshold for consideration as a cost-saving intervention (because of offsets by future HIV treatment costs averted). An optimized portfolio of these specific interventions could result in up to a 34% reduction in new HIV infections over the next 20 years. The cost-per-infection averted of the portfolio was estimated to be 106,378; the total cost was in excess of 2billion(overthe20yearperiod,orapproximately2 billion (over the 20 year period, or approximately 100 million per year, on average). The cost-savings of prevented infections was estimated at more than 5billion(orapproximately5 billion (or approximately 250 million per year, on average).Conclusions:Optimal implementation of a portfolio of evidence-based interventions can have a substantial, favorable impact on the ongoing HIV epidemic in NYC and provide future cost-saving despite significant initial costs. © 2013 Kessler et al

    What Do Prosecutors Maximize? An Analysis of Drug Offenders and Concurrent Jurisdiction

    This paper presents a model of prosecutors' decision-making processes in which prosecutors (both federal and state) internalize some of the benefits of reducing crime, but also care about developing their own human capital. Since U.S. attorneys make their decision first, they have the opportunity to take the cases that will further their human capital development, knowing that the local district attorneys will handle the other cases. Using two surveys on prison admissions, we find that defendants who are better educated, richer, married, white, have higher-paying occupations more likely to be incarcerated in the federal system. Conversely, state prisons are more likely to incarcerate individuals who are particularly likely to be difficult prisoners, despite the supposed advantages of federal prisons in dealing with the most dangerous criminals.

    The effectiveness and cost-effectiveness of mindfulness-based cognitive therapy compared with maintenance antidepressant treatment in the prevention of depressive relapse/recurrence: results of a randomised controlled trial (the PREVENT study)

    Background: Individuals with a history of recurrent depression have a high risk of repeated depressive relapse/recurrence. Maintenance antidepressant medication (m-ADM) for at least 2 years is the current recommended treatment, but many individuals are interested in alternatives to m-ADM. Mindfulness-based cognitive therapy (MBCT) has been shown to reduce the risk of relapse/recurrence compared with usual care but has not yet been compared with m-ADM in a definitive trial. Objectives: To establish whether MBCT with support to taper and/or discontinue antidepressant medication (MBCT-TS) is superior to and more cost-effective than an approach of m-ADM in a primary care setting for patients with a history of recurrent depression followed up over a 2-year period in terms of preventing depressive relapse/recurrence. Secondary aims examined MBCT’s acceptability and mechanism of action. Design: Single-blind, parallel, individual randomised controlled trial. Setting: UK general practices. Participants: Adult patients with a diagnosis of recurrent depression and who were taking m-ADM. Interventions: Participants were randomised to MBCT-TS or m-ADM with stratification by centre and symptomatic status. Outcome data were collected blind to treatment allocation and the primary analysis was based on the principle of intention to treat. Process studies using quantitative and qualitative methods examined MBCT’s acceptability and mechanism of action. Main outcomes measures: The primary outcome measure was time to relapse/recurrence of depression. At each follow-up the following secondary outcomes were recorded: number of depression-free days, residual depressive symptoms, quality of life, health-related quality of life and psychiatric and medical comorbidities. Results: In total, 212 patients were randomised to MBCT-TS and 212 to m-ADM. The primary analysis did not find any evidence that MBCT-TS was superior to m-ADM in terms of the primary outcome of time to depressive relapse/recurrence over 24 months [hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.67 to 1.18] or for any of the secondary outcomes. Cost-effectiveness analysis did not support the hypothesis that MBCT-TS is more cost-effective than m-ADM in terms of either relapse/recurrence or quality-adjusted life-years. In planned subgroup analyses, a significant interaction was found between treatment group and reported childhood abuse (HR 1.89, 95% CI 1.06 to 3.38), with delayed time to relapse/recurrence for MBCT-TS participants with a more abusive childhood compared with those with a less abusive history. Although changes in mindfulness were specific to MBCT (and not m-ADM), they did not predict outcome in terms of relapse/recurrence at 24 months. In terms of acceptability, the qualitative analyses suggest that many people have views about (dis)/continuing their ADM, which can serve as a facilitator or a barrier to taking part in a trial that requires either continuation for 2 years or discontinuation. Conclusions: There is no support for the hypothesis that MBCT-TS is superior to m-ADM in preventing depressive relapse/recurrence among individuals at risk for depressive relapse/recurrence. Both treatments appear to confer protection against relapse/recurrence. There is an indication that MBCT may be most indicated for individuals at greatest risk of relapse/recurrence. It is important to characterise those most at risk and carefully establish if and why MBCT may be most indicated for this group

    Study protocol for a randomized controlled trial comparing mindfulness-based cognitive therapy with maintenance anti-depressant treatment in the prevention of depressive relapse/recurrence: the PREVENT trial.

    BACKGROUND: Depression is a common and distressing mental health problem that is responsible for significant individual disability and cost to society. Medication and psychological therapies are effective for treating depression and maintenance anti-depressants (m-ADM) can prevent relapse. However, individuals with depression often express a wish for psychological help that can help them recover from depression in the long-term. We need to develop psychological therapies that prevent depressive relapse/recurrence. A recently developed treatment, Mindfulness-based Cognitive Therapy (MBCT, see http://www.mbct.co.uk) shows potential as a brief group programme for people with recurring depression. In two studies it has been shown to halve the rates of depression recurring compared to usual care.This trial asks the policy research question, is MBCT superior to m-ADM in terms of: a primary outcome of preventing depressive relapse/recurrence over 24 months; and, secondary outcomes of (a) depression free days, (b) residual depressive symptoms, (c) antidepressant (ADM) usage, (d) psychiatric and medical co-morbidity, (e) quality of life, and (f) cost effectiveness? An explanatory research question asks is an increase in mindfulness skills the key mechanism of change? METHODS/DESIGN: The design is a single blind, parallel RCT examining MBCT vs. m-ADM with an embedded process study. To answer the main policy research question the proposed trial compares MBCT plus ADM-tapering with m-ADM for patients with recurrent depression. Four hundred and twenty patients with recurrent major depressive disorder in full or partial remission will be recruited through primary care. Depressive relapse/recurrence over two years is the primary outcome variable. The explanatory question will be addressed in two mutually informative ways: quantitative measurement of potential mediating variables pre/post-treatment and a qualitative study of service users' views and experiences. DISCUSSION: If the results of our exploratory trial are extended to this definitive trial, MBCT will be established as an alternative approach to maintenance anti-depressants for people with a history of recurrent depression. The process studies will provide evidence about the effective components which can be used to improve MBCT and inform theory as well as other therapeutic approaches.
