Injecting nation: achieving control of hepatitis C in Australia

Since Australia banned heroin in 1953 consumption of illicit drugs, deaths, crime and corruption related to drugs have steadily increased. Injecting drug use (IDU) in Australia is now a significant public health problem linked each year to approximately 500 overdose deaths and more than 6000 hepatitis C infections. At least 85% of prevalent and incident hepatitis C cases in Australia are injecting drug users (IDUs) with annual incidence estimated at 15%. Although poorly documented, increasing numbers of patients with end-stage liver disease from hepatitis C now appear to present in Australia. This reflects a heroin-injecting epidemic commencing a quarter of a century ago, the close association between drug injecting and hepatitis C and the long delay between hepatitis C infection and complications. The overall health and economic burden of hepatitis C may soon exceed HIV. Control is far more difficult to achieve for hepatitis C than HIV because of much higher baseline prevalence levels and far greater infectiousness by blood to blood spread. Transmission appears to follow minimal breaches of infection control guidelines. Hepatitis C has not yet become a priority public health issue in Australia. No national prevention strategy has been proposed. Prevention strategies (such as needle exchange or methadone) which controlled HIV among IDUs should be expanded, with the expectation of some useful reduction of spread but without achieving control of hepatitis C. Other options for control must be considered. Eradicating illicit drug use in Australia is unachievable. Virtually eradicating injecting drug use by facilitating a switch to non-injecting routes of administration (NIROA) is achievable (although difficult) and this could control hepatitis C. NIROA will have the probable additional benefit of reducing drug overdose deaths. NIROA has begun recently to replace injecting in several countries without government intervention. Powerful cultural, pharmacological and economic factors strongly reinforce drug injecting. Economic impediments to NIROA could be reduced by drug policy reform. Facilitating a switch to NIROA carries some risk of increased discrimination directed against an already marginalized population. A major obstacle to harm reduction is the common assumption that any relaxation of drug policy invariably leads to increased consumption. Switching the predominant route of administration of illicit drugs from IDU to NIROA should be the major focus of national efforts to control hepatitis C and overdose deaths in Australia.     

Accounting for susceptibility in risk assessment: The need for full disclosure

Many Environmental Laws create the unrealistic expectation that science can be used to determine ‘safety'. The many uncertainties surrounding environmental risks, as well as individual, group and societal differences about what is considered ‘safe', make it inevitable that policy decisions must be made. It is appropriate that such decisions be shaped by politics and social issues, as well as be informed by science and economics, but care should be taken to distinguish between policy and fact. Not much is known about the nature and magnitude of environmental susceptibilities. Credible environmental decisions require that scientists, risk assessors and decision-makers acknowledge this, and that they take care to distinguish policy calls from scientific fact.     

Cannabis laws: an analysis of costs

There is evidence that the use of cannabis is increasing in Australia, with stable black-market prices, despite the 9-year National Campaign Against Drug Abuse, increasing expenditure to enforce the laws against cannabis use, and the seizure of large plantations of cannabis plants. Recent government data are used to estimate the conservative cost of drug-law enforcement against cannabis use as being $329m in 1991-92. Alternatives to the existing regime are examined, including expiation, decriminalization, and legalization.     

The development of guidelines for drug and alcohol dependence treatment: affecting policy and practice

The rationale and methodology behind the Australian Quality Assurance Project is described. The Project aimed to develop guidelines for treatment content based on three sources of information: research findings, current practice and expert opinion. The issue of the gap between research and practice is discussed, as well as the role of dissemination in altering clinician behaviour.     

Harnessing harm reduction in Australia: an interview with the Hon. Neal Blewett. Interview by Steve Allsop

The National Campaign Against Drug Abuse (NCADA) was established in April 1985. Aiming to provide a national framework to minimize the harmful consequences of drug use, the original 3-year programme was extended to 1997. A key figure in the NCADA, Dr Neal Blewett, was interviewed to gain his perspective on the development and implementation of the Campaign over its first 10 years.

A Systemic and Value-Based Approach to Strategic Reform of the Mental Health System

Most writers now recognize that mental health policy and the mental health system are extremely resistant to real changes that reflect genuine biopsychosocial paradigms of mental disorder. Writers bemoaning the intransigence of the mental health system tend to focus on a small analytical level, only to find themselves mired in the rationalities of the existing system. Problems are acknowledged to be system-wide, yet few writers have used a method of analysis appropriate for systemic problems. Drawing upon the General System Theory (GST) analytical perspective, this article advances a systematic approach to understand the mental health system and to facilitate the development of reform strategies that recognize the system's complexity and changing nature. The article first discusses the failure of major reform efforts in the mental health system and the limitations of mainstream analysis of mental health politics and policies with respect to the objectives of analysis and reform. This article describes how systems thinking has thus far influenced the study of the mental health policy and politics system, and argues that a systemic perspective is profitable for reconceiving the mental health system, enabling a fresh basis for the development of reform strategies. The mental health system should be seen as a social system influenced by larger political and economic dimensions, not just as a 'delivery system' scientifically constructed by neutral experts. Furthermore, the policy planning process should be viewed as part and parcel of a mental health system modeled as complex and dynamic. The systemic perspective outlined here should help both to clarify the value-based objectives that we hold for the system and, consequently, to plan for the strategic reforms that have so far eluded us.

Elderly immigrants and the saga of welfare reform

In 1996 Congress enacted legislation which, among other things, substantially cut off Supplemental Security Income payments and food stamps for present and future legal alien residents of the United States, and made it much harder for them to qualify for Medicaid. For low-income elderly immigrants, who constituted more than two-thirds of aliens on SSI, the adverse and potential impacts were substantial in terms of economic hardship and access to health care. In the months that followed, their plight received significant attention from the media and state and local politicians who now had greater economic and social responsibilities thrust upon them. One year later, Congress restored SSI benefits only for aliens who been receiving them before August 22, 1996 and made it easier for them to qualify for Medicaid. Food stamp benefits, however, were not restored. The limited scope of this restoration of benefits means that many of today's older immigrants, as well as those in the future, will be faced with serious problems in meeting their basic income and health care needs.     

Challenges of and strategies for changing prescribing practices of health care providers

Problems related to inappropriate prescribing practices of physicians in general are well recognized. Dietary fluoride supplements have been implicated as one of the contributing factors in an increase in dental fluorosis. Inappropriate prescribing practices of providers have been cited as a major factor in this implication. Numerous studies of physicians and dentists have documented a lack of knowledge and inappropriate prescribing practices regarding fluoride supplements. The purpose of this paper is to identify barriers to changing fluoride-prescribing practices of health care providers and to suggest strategies for implementing change. To increase optimal and appropriate use of fluoride supplements, educational interventions are necessary for all user groups--detail men and women, physicians, dentists, pharmacists, nurse practitioners, dental hygienists, and the public. In addition, environmental supports for the educational activities in the form of policy, regulation, standards of care, and guidelines are recommended for consideration.
