Published by the National Centre for Education and Training on Addiction (NCETA). www.nceta.flinders.edu.au Design and layout by Inprint Design www.inprint.com.au Foreword Over recent years, there has been growing awareness of potential harms that can result from the misuse of pharmaceutical drugs. This concern culminated in the decision by the Ministerial Council on Drugs (MCDS) through the Inter-Governmental Committee on Drugs (IGCD) to take decisive action to develop a comprehensive set of strategic responses. This task was overseen by Victorian Department of Health who in 2010 called for tenders to undertake the development of Australia’s first national strategy to address pharmaceutical drug misuse. The National Centre for Education & Training on Addiction (NCETA) headed a consortium that was awarded this tender. As part of the process of developing the strategy, a comprehensive examination was undertaken of relevant contextual factors. This document provides a summary overview of these contextual factors. It is hoped that this document will contribute to understanding the complex nature of pharmaceutical misuse and will help inform appropriate preventive responses. NCETA The National Centre for Education and Training on Addiction is an internationally recognised research centre that works as a catalyst for change in the alcohol and other drugs (AOD) field. Our mission is to advance the capacity of organisations and workers to respond to alcohol-and drug-related problems. Our core business is the promotion of workforce development (WFD) principles, research and evaluation of effective practices; investigating the prevalence and effect of alcohol and other drug use in society; and the development and evaluation of prevention and intervention programs, policy and resources for workplaces and organisations. NCETA is based at Flinders University and is a collaboration between the University, the Australian Government Department of Health and Ageing and the SA Department of Health.

  • The Frail Elderly and Integral Health Management Centered on the Individual and the Family Editorial 307
    http://dx.doi.org/10.1590/1981-22562017020.170061 The frail elderly and integral health management centered on the individual and the family Editorial 307 The rapid aging of the Brazilian population, combined with an increase in longevity, has had serious consequences for the structure of health care networks, with an increased burden of chronic diseases and especially of functional disabilities. Unfortunately, the care offered to frail elderly people with multiple chronic health conditions, poly-disabilities or complex needs is fragmented, inefficient, ineffective and discontinuous, which can further harm their health. The hospital-based health system of the 19th and 20th centuries that is designed to deal with acute and especially infectious diseases is inadequate for meeting the needs of chronic patients for long-term, continuous treatment. The response of the health system to the new demands means the use of a set of management technologies that are capable of ensuring optimal standards of health care in a resolutive, efficient, scientifically structured manner, which is safe for patients and health professionals, timely, equitable, humanized and sustainable, is essential. The threefold goal of a better care experience, coupled with improved populational health and reduced costs developed by the Institute of Healthcare Improvement (Triple Aim), is the best strategy for reorganizing and optimizing health system performance. Providing the best care experience means understanding the particularities of health in the elderly. The use of parameters based on risk factors, diseases and/or age is inappropriate and is associated with a high risk of iatrogenic illness. Vitality is extremely heterogeneous among the elderly and chronological age is a precarious metric for the assessment of the homeostatic reserve of the individual.

  • Conference Book
    2017 EACME Annual Conference “Justice in Health Care – Values in Conflict” September 7-9, 2017 Barcelona CONFERENCE BOOK ii Welcome to Barcelona Both the European Association of Centres of Medical Ethics (EACME) and the Borja Institute of Bioethics-Ramon Llull University (Barcelona) organize the 2017 EACME Annual Conference. The European Association of Centres of Medical Ethics (EACME) is, since its creation in December 1986, an international research and communication network with the aim to promote research, education and consultation in the field of (bio)- medical ethics. The Borja Institute of Bioethics-Ramon Llull University (Barcelona) was founded in 1976 with the main goal of studying in depth the problems raised by progress in biomedical science and its implications for society and its values, disseminating its findings in specialized publications. Recent developments in several countries in Europe, such as austerity measures, lead to concerns about the conflict between justice in health care with other eco- nomic and political values. That is why the Programme of 2017 EACME Annual Conference, under the topic \Justice in Health Care { Values in Conflict”, focuses on the following important issues: • Determinants of Health { What does health mean? Looking beyond WHO definition { Lifestyles and health { Quality of life { Social expectations and medicalisation of life { Salutogenesis and health-promotion activities • Healthcare Systems: at the Service of What? { Ethical issues in different models of Healthcare Systems { Sustainability

  • 1 Proposal to WONCA Executive Establish a Special Interest Group
    Proposal to WONCA Executive Establish a Special Interest Group on Quaternary Prevention and Overmedicalization Introduction: Justification and Importance “Medicine increasingly focuses on the problems that result from an excess of medical care, in particular overscreening and overdiagnosis. In a new framework or paradigm, based on patient doctor relationships, quaternary prevention (P4) describes the protection of patients from diagnostic tests, interventions and treatments that offer no benefit for overall morbidity or mortality for the individual, and may cause physical or psychological harm. It includes the protection of patients from misled well-meaning doctors and from a system in which the commercial interests of pharmaceutical and diagnostic companies, and governments working in a marketised model of health care, that can distort care, medicalize normal life and waste resources”. Jamoulle M, Mangin D (not published). Definitions The original definition of Quaternary Prevention was formulated in 1986 Action taken to identify patient at risk of overmedicalization, to protect him from new medical invasion, and to suggest to him interventions, which are ethically acceptable.1 WONCA International Dictionary of General/Family Practice, accepted the term in 1999.2 The concept of quaternary prevention is grounded in the ethical principles of medicine, an epistemological understanding of a paradigm crisis or struggle that is challenging the predominant biological paradigm in health, and the realization of a movement that includes citizens, patients, care providers and public health policies. Quaternary prevention provides a complex but necessary approach oriented to provide person -focused care; promote equity in healthcare; prevent overdiagnosis, unnecessary interventions, and avoid harm: and so, in few words, to humanize medicine.

  • (Iha) Meeting Report
    Justification of the Use of CT in Asymptomatic People for Individual Health Assessment (IHA) 26-28 September 2016, Seoul, Korea Workshop organized by the World Health Organization (WHO), in cooperation with the Korean Society of Radiology (KSR) and the Korean National Evidence-based Healthcare Collaborating Agency (NECA) MEETING REPORT 1. Introduction Constant innovation of health technology has expanded the applications of radiation in medical imaging and improved patient care. The justification of such exposures is based on the judgment that the clinical benefit of the medical imaging procedure will outweigh the radiation detriment. The established scenario for medical imaging in many parts of the world involves a patient with signs and/or symptoms being referred to a radiological procedure. In this scenario, the healthcare service is provided to people with a clinical condition to determine the presence or absence of disease, as a basis for making further treatment decisions. In this scenario, evidence-based imaging referral guidelines developed for a number of clinical conditions can support the justification process and enhance appropriateness of referrals by informing referrers and radiologists of the most appropriate examination. The scenario is different when medical imaging is performed on apparently healthy people (i.e. asymptomatic people) to detect early disease or risk factors for disease. In this context, medical imaging may take place within a formal population screening program (e.g. national mammography screening programs) or as an individual health assessment (IHA). The present workshop was built upon the outcomes of an expert consultation kindly hosted by Bundesamt fur Strahlenshutz (BfS) in Munich, Germany, in October 20141Error! Reference source not found.

Florianópolis, SC, Brasil. Quaternary Prevention (P4) is an action taken to identify patients at risk of overmedicalisation, to protect them from new medical invasions, and to suggest interventions ethically acceptable. Recently, three European articles have proposed a new definition: “to protect individuals from more harmful than beneficial interventions”. The objective is to discuss this proposal critically. We have identified and analysed seven criticisms to P4 original definition. Five are unfounded: (1) Ethically vague; (2) Restricted scope; (3) Creation of an unnecessary step; (4) Focus on medicalisation; (5) Demedicalisation non-scientific based. The remaining two do not justify a new definition: (6) Changing visual representation; (7) Centeredness on Evidence-Based Medicine (EBM). The new proposal reduces the scope of P4 and the professional role. The original definition is robust and incorporates the challenge of social/cultural iatrogeny resulting from overmedicalisation, partially unattainable via EBM. Keywords: Quaternary prevention.
