Sensitivity and Specificity. Wikipedia. Last Modified on 16 November 2013
Sensitivity and specificity - Wikipedia, the free encyclopedia Create account Log in Article Talk Read Edit View Sensitivity and specificity From Wikipedia, the free encyclopedia Main page Contents Sensitivity and specificity are statistical measures of the performance of a binary classification test, also known in statistics as Featured content classification function. Sensitivity (also called the true positive rate, or the recall rate in some fields) measures the proportion of Current events actual positives which are correctly identified as such (e.g. the percentage of sick people who are correctly identified as having Random article the condition). Specificity measures the proportion of negatives which are correctly identified as such (e.g. the percentage of Donate to Wikipedia healthy people who are correctly identified as not having the condition, sometimes called the true negative rate). These two measures are closely related to the concepts of type I and type II errors. A perfect predictor would be described as 100% Interaction sensitive (i.e. predicting all people from the sick group as sick) and 100% specific (i.e. not predicting anyone from the healthy Help group as sick); however, theoretically any predictor will possess a minimum error bound known as the Bayes error rate. About Wikipedia For any test, there is usually a trade-off between the measures. For example: in an airport security setting in which one is testing Community portal for potential threats to safety, scanners may be set to trigger on low-risk items like belt buckles and keys (low specificity), in Recent changes order to reduce the risk of missing objects that do pose a threat to the aircraft and those aboard (high sensitivity). -

Is This a Seeding Trial? by Mark Hochhauser
Vol. 5, No. 6, June 2009 “Can You Handle the Truth?” Is this a Seeding Trial? By Mark Hochhauser Seeding trials are clinical studies primarily intended to promote use of the study drug by physicians and/or to convert physicians, especially opinion leaders — and study subjects — into advocates for the study drug. Seeding trials seed the market with product samples. The sponsor hopes that physicians and patients will continue using the drug after the trial. Seeding trials are unethical because they exploit study subjects for commercial purposes, create little or no medically useful knowledge, and deceive researchers, subjects and IRBs. In the interest of protecting human welfare, institutional review boards (IRBs) should not approve seeding trials. A seeding trial can occur only because the sponsor “does not disclose its true purpose to anyone who could say ‘no.’” 1 (p. 279) The question for the IRB thus becomes: Is the study under review a seeding trial? Inexperienced investigators and IRB members may not be familiar with the characteristics of seeding trials. Table 1 summarizes the six seeding trial criteria of Kessler, et al2 and six additional criteria of Sox and Rennie1. These researchers suggested that clinical trials sharing one or more of these flaws might be seeding trials, although some information may be difficult or impossible for the IRB to obtain. With the criteria in Table 1, IRBs can identify most seeding studies. Case Study Our IRB reviewed a Phase IIIb rollover trial (“Study A”) using subjects from a Phase III study. Phase III trials are large, multicenter, randomized controlled trials designed to evaluate a drug’s effectiveness in comparison to the standard treatment. -
Recruiting Human Subjects: Industry-Sponsored Clinical Research
Department of Health and Human Services OFFICE OF INSPECTOR GENERAL Recruiting Human Subjects Pressures in Industry-Sponsored Clinical Research JUNE GIBBS BROWN Inspector General JUNE 2000 OEI-01-97-00195 OFFICE OF INSPECTOR GENERAL The mission of the Office of Inspector General (OIG), as mandated by Public Law 95-452, is to protect the integrity of the Department of Health and Human Services programs as well as the health and welfare of beneficiaries served by them. This statutory mission is carried out through a nationwide program of audits, investigations, inspections, sanctions, and fraud alerts. The Inspector General informs the Secretary of program and management problems and recommends legislative, regulatory, and operational approaches to correct them. Office of Evaluation and Inspections The Office of Evaluation and Inspections (OEI) is one of several components of the Office of Inspector General. It conducts short-term management and program evaluations (called inspections) that focus on issues of concern to the Department, the Congress, and the public. The inspection reports provide findings and recommendations on the efficiency, vulnerability, and effectiveness of departmental programs.

Clinical Researcher™ The Authority in Ethical, Responsible Clinical Research April 2018 Volume 32, Issue 4 All contents © 2018 ACRP. All Rights Reserved Clinical Researcher—April 2018 (Volume 32, Issue 4) EXECUTIVE DIRECTOR’S MESSAGE Bringing the Team Together Jim Kremidas [DOI: 10.14524/CR-18-4025] With our ACRP 2018 annual meeting just 10 days away (as of the posting of this issue of Clinical Researcher), it’s an appropriate time to reflect on how we can all work together toward our common goal: providing the highest possible quality in the delivery of clinical trials. We’re all an integral part of a team effort full of dedicated professionals. Working together, we learn from each other. Learning together, we thrive. ACRP’s conference is an excellent opportunity for thought leaders to huddle together to share best practices. To build on what’s working and learn from what isn’t. You and your organization have some ambitious goals. We’ve been working with others in the industry to advance the professionalization of the clinical trial workforce by developing real- world standards based on the competencies required to be an outstanding researcher. We’re also working to spotlight some of the highest performers in our industry. That’s one of the many reasons we’re excited about working with The Avoca Group to jointly recognize leading sponsors and contract research organizations (CROs) at the ACRP/Avoca Awards & Recognition Ceremony on Friday, April 27, during our annual meeting. Finalists for the ACRP/Avoca Quality Awards were chosen by investigational sites through a research study conducted in conjunction with The Avoca Group over an eight-week period in early 2018. -
[T]His Advertising Promotes Only the Most Expensive
presents "[T]his advertising promotes only the most expensive products, it drives prescription costs up and also encourages the 'medicalization' of American life — the sense that pills are needed for most everyday problems that people notice, and many that they don’t." — Jerry Avorn, New York Times Convincing people they are sick and need a drug is a multi-billion dollar industry. In 2015, Big Pharma dropped a record- breaking $5.4 billion on direct-to-consumer (DTC) ads, according to Kantar Media. And it paid off for Big Pharma. The same year, Americans spent a record $457 billion on prescription drugs. The U.S. and New Zealand are the only countries where DTC is legal. Americans also pay more for drugs and devices than any other country. The bulk of these ads appear on TV at a rate of 80 ads per hour of programming, according to Nielsen. Behind the drug and device ads saturating TV, radio and digital media are hidden costs and devastating side effects that companies don't advertise, and critics say the ads drive up drug prices and erode the patient-doctor relationship. With the price of drugs skyrocketing, politicians and health-care providers question Pharma's DTC spending, which exceeds money spent on research and development. Even presidential hopeful Hillary Clinton called for an end to tax breaks for drug ads and for tougher regulations. But the money spent on DTC is just one small cog in Big Pharma's well-oiled marketing machine. Companies spend billions more on getting doctors to write prescriptions for their expensive brand-name drugs or devices for uses not approved by the Food and Drug Administration — a controversial practice called off-label marketing. -
Science and Commerce in Medical Epistemology DISSERTATION
UNIVERSITY OF CALIFORNIA, IRVINE The Fundamental Antagonism: Science and Commerce in Medical Epistemology DISSERTATION submitted in partial satisfaction of the requirements for the degree of DOCTOR OF PHILOSOPHY in Philosophy by Bennett Harvey Holman Dissertation Committee: Professor P. Kyle Stanford, Chair Professor Jeffrey Barrett Associate Professor Kent Johnson Distinguished Professor Brian Skyrms 2015 Portion of Chapter 5 © 2015 University of Chicago Press. Chapter 6 © 2015 University of Chicago Press All other materials © 2015 Bennett Harvey Holman DEDICATION To: My father who inspired me to make the world a better place. And My mother who demanded that I love my work. I learned this, at least, by my experiment: that if one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours. He will put some things behind, will pass an invisible boundary; new, universal, and more liberal laws will begin to establish themselves around and within him; or the old laws be expanded, and interpreted in his favor in a more liberal sense, and he will live with the license of a higher order of beings. In proportion as he simplifies his life, the laws of the universe will appear less complex, and solitude will not be solitude, nor poverty poverty, nor weakness weakness. If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them. Henry David Thoreau Walden No one who has not given the subject especial attention can imagine what impudent mendacity, what incredibly absurd claims, what impossible statements, are indulged in by those nostrum manufacturers who have made the physician their special prey… It is a false and pernicious theory that error should be left alone; that it will die out by itself. -
Sponsorship Bias in Clinical Trials
Sponsorship bias in clinical trials Nr 11 | 2015 (49) | Page 123-130 | Main article | 21-11-2015 Joel Lexchin, the author of the translated article, indicates that the pharmaceutical industry is in a situation of conflict. The economic fate of pharmaceutical companies depends on the favourable outcomes of the trials they sponsor, which may make it tempting for them to try and influence studies they are involved in. This situation exists not only in the pharmaceutical industry, but also in the tobacco industry, the banking community, the food and drinks industry and even, as has recently emerged, in the automotive industry. Lexchin mentions several interventions that the pharmaceutical industry can use to influence the results of the scientific research they sponsor. When these positively biased? results are published in journals as research papers, readers who are unaware of this bias can be misled. Below we discuss a number of points that could help readers evaluate papers that present overly optimistic messages. In fact, most of these aspects have already been discussed in previous issues of Geneesmiddelenbulletin. In Gebu 2012; 46: 138-145, Lexchin discussed several aspects of the way the pharmaceutical industry is influencing the results of clinical drug trials. The present article can be regarded as a further clarification of these matters. Information about new drugs should not be provided by persons who might stand to gain financially from the information provided, even more so when gifts or presents are involved. When doctors of pharmacists read or discuss articles, it might be useful if they do so together with an expert on evidence-based medicine (EBM). -
