Involving peers in research: the UNSW community reference panel.

There is limited literature about how to best "do" community involvement in research and no one model of community involvement in research that has been shown to be more effective than others. This paper presents one way to receive the input of people with experiences relevant to research with marginalised groups, including people who use and inject drugs. The UNSW Community Reference Panel is a virtual network of people from across Australia who are engaged to provide input and consultation on research design, processes, materials, and outputs. Although this panel goes some way towards community involvement and consultation in the research process, it does not take the place of other aspects of community governance and ownership, especially as informed by principles of research with Indigenous peoples. This model is an example of a means to bring the voices and perspectives of people who are generally excluded from the research and decision-making structures that affect their lives, including people who inject drugs, to influence the questions that are asked in research, how research gets done, and to what purpose research findings are put.

Introducing hepatitis C virus healthcare pathways in addiction care in the Netherlands with a Breakthrough project: a mixed method study.

BACKGROUND: People who inject drugs (PWID) are disproportionally affected by the hepatitis C virus (HCV) infection. In the Netherlands, active HCV transmission in PWID has practically been halted but uptake of HCV testing and linkage to care remains insufficient in this risk group. A national HCV in Addiction Care (HAC) quality improvement project based on the Breakthrough methodology (i.e. Breakthrough project) aimed to secure proper linkage to care in PWID by introducing local HCV healthcare screening and treatment pathways in addiction care units. AIM: To qualitatively appraise the local HCV healthcare pathways; to evaluate the yield in terms of number of PWID screened, diagnosed, referred, and treated; and to identify best practices and barriers to successful participation in the HAC Breakthrough project. METHODS: Between 2013 and 2016, 12 units of addiction care centers throughout the Netherlands participated in two series of a HAC Breakthrough project. Local multidisciplinary teams created HCV healthcare pathways. Quality assessment of HCV healthcare pathways was performed retrospectively and data on screening results was collected. In-depth interviews were conducted to elucidate best practices and essential elements for successful participation. RESULTS: In total, six HCV healthcare pathways were submitted by ten teams of which 83% was judged to be of "good" or "sufficient" quality. Uptake of HCV-antibody screening was 40% (N = 487/1219) and uptake of HCV-RNA in HCV-antibody positives was 59% (N = 107/181). The project resulted in 76 (6%) newly detected cases of persistent HCV viremia. Of all HCV-RNA positives, 92% was referred to a hepatitis treatment center. In 39% (N = 27/70) of those referred, treatment initiation was documented and 82% (N = 22/27) achieved a sustained virological response. Teams identified several best practices including motivational counseling training, oral swabs for anti-HCV testing, facilitating complementary HCV RNA testing, and supervised hospital visits. CONCLUSION: The HAC Breakthrough project has brought about good quality HCV healthcare pathways in the majority of participating addiction care centers and has successfully linked PWID with ongoing HCV viremia to care. Uptake of HCV screening and treatment after referral were identified as the main gaps to be closed in the HCV cascade of care to achieve final HCV elimination in Dutch PWID (i.e. micro-elimination).

Clinical effectiveness of pharmacy-led versus conventionally delivered antiviral treatment for hepatitis C in patients receiving opioid substitution therapy: a study protocol for a pragmatic cluster randomised trial.

INTRODUCTION: Hepatitis C virus (HCV) infection affects 0.7% of the general population, and up to 40% of people prescribed opioid substitution therapy (OST) in Scotland. In conventional care, less than 10% of OST users are tested for HCV and less than 25% of these initiate treatment. Community pharmacists see this group frequently to provide OST supervision. This study examines whether a pharmacist-led 'test & treat' pathway increases cure rates for HCV. METHODS AND ANALYSIS: This protocol describes a cluster-randomised trial where 60 community pharmacies provide either conventional or pharmacy-led care. All pharmacies offer dried blood spot testing (DBST) for HCV. Participants have attended the pharmacy for OST for 3 months; are positive for HCV genotype 1 or 3; are not co-infected with HIV and/or hepatitis B; have no decompensated liver disease; are not pregnant. For conventional care, pharmacists refer HCV-positive participants to a local centre for assessment. In the pharmacy-led arm, pharmacists assess participants themselves in the pharmacy. Drug prescribing is by nurse prescribers (conventional arm) or pharmacist prescribers (pharmacy-led arm). Treatment in both arms is delivered as daily modified directly observed therapy in a pharmacy. Primary trial outcome is number of sustained virological responses at 12 weeks after treatment completion. Secondary trial outcomes are number of tests taken; treatment uptake; completion; adherence; re-infection. An economic evaluation will assess potential cost-effectiveness. Qualitative research interviews with clients and health professionals assess acceptability of a pharmacist-led pathway. ETHICS AND DISSEMINATION: This protocol has been ethically approved by the East of Scotland Research Ethics Committee 2 (15/ES/0086) and complies with the Declaration of Helsinki and principles of Good Clinical Practice. Caldicott guardian approval was given on 16 December 2016 to allow NHS Tayside to pass information to the cluster community pharmacies about the HCV test status of patients that they are seeing to provide OST supervision. NHS R&D approvals have been obtained from each health board taking part in the study. Informed consent is obtained before study enrolment and only anonymised data are stored in a secured database, enabling an audit trail. Results will be submitted to international peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT02706223; Pre-results.

Development and Preliminary Evaluation of an Integrated Cognitive-Behavior Treatment for Chronic Pain and Substance Use Disorder in Patients with the Hepatitis C Virus.

OBJECTIVE: Individuals with the hepatitis C virus (HCV) have high rates of both chronic pain and substance use disorder (SUD). Despite high comorbidity, there are limited data available on effective methods of treatment for co-occurring chronic pain and SUD. In this study, we sought to develop and conduct preliminary testing of an integrated cognitive-behavior therapy (CBT) for chronic pain and SUD in patients with HCV. DESIGN: Descriptive, including pretreatment, posttreatment, and follow-up testing. SETTING AND PATIENTS: Outpatient clinic as part of one VA Medical Center. PARTICIPANTS: Veterans with chronic pain, SUD, and HCV. INTERVENTION: Eight-session integrated group CBT for chronic pain and SUD in patients with HCV. METHODS: Participants completed standardized measures of pain, function, depression severity, and alcohol and substance use at baseline, post-treatment, and 3-month follow-up. RESULTS: Generalized estimating equations identified improvements in pain interference, reducing cravings for alcohol and other substances, and decreasing past-month alcohol and substance use. The proportion of participants who met diagnostic criteria for current SUD demonstrated a four-fold decrease over the course of the study from 24% at baseline to 15% at post-treatment and 6% at 3-month follow-up. On response to a global impression of change, 94% of participants noted improvement from baseline. CONCLUSIONS: Results from this pilot study suggest that a customized CBT for patients with both chronic pain and SUD (CBT-cp.sud) may be beneficial in improving important pain and addiction-related outcomes in patients with HCV. Larger scale investigations of this intervention appear warranted.

[Hepatitis C: diagnosis, anti-viral therapy, after-care. Hungarian consensus guideline]. / Hepatitis C-vírus-fertozés: diagnosztika, antivirális terápia, kezelés utáni gondozás. Magyar konszenzusajánlás.

Approximately 70,000 people are infected with hepatitis C virus in Hungary, and more than half of them are not aware of their infection. From the point of infected individuals early recognition and effective treatment of related liver injury may prevent consequent advanced liver diseases and complications (liver cirrhosis, liver failure and liver cancer) and can increase work productivity and life expectancy. Furthermore, these could from prevent further spread of the virus as well as reduce substantially long term financial burden of related morbidity, as a socioeconomic aspect. Pegylated interferon + ribavirin dual therapy, which is available in Hungary since 2003, can clear the virus in 40-45% of previously not treated (naïve), and in 5-21% of previous treatment-failure patients. Addition of a direct acting first generation protease inhibitor drug (boceprevir or telaprevir) to the dual therapy increases the chance of sustained viral response to 63-75% and 59-66%, respectively. These two protease inhibitors are available and financed for a segment of Hungarian patients since May 2013. Between 2013 and February 2015, other direct acting antivirals and interferon-free combination therapies have been registered for the treatment of chronic hepatitis C with a potential efficacy over 90% and typically with a short duration of 8-12 weeks. Indication of therapy includes exclusion of contraindications to the drugs and demonstration of viral replication with consequent liver injury, i.e., inflammation and/or fibrosis in the liver. Non-invasive methods (elastography and biochemical methods) are accepted and preferred for staging liver damage (fibrosis). For initiation of treatment accurate and timely molecular biology tests are mandatory. Eligibility for treatment is a subject of individual central medical review. Due to budget limitations therapy is covered only for a proportion of patients by the National Health Insurance Fund. Priority is given to those with urgent need based on a Hungarian Priority Index system reflecting primarily the stage of liver disease, and considering also additional factors, i.e., activity and progression of liver disease, predictive factors of treatment and other special issues. Approved treatments are restricted to the most cost-effective combinations based on the cost per sustained viral response value in different patient categories with consensus between professional organizations, National Health Insurance Fund and patient organizations. More expensive therapies might be available upon co-financing by the patient or a third party. Interferon-free treatments and shorter therapy durations preferred as much as financially feasible. A separate budget is allocated to cover interferon-free treatments for the most-in-need interferon ineligible/intolerant patients, and for those who have no more interferon-based therapy option.

[Representations of Care of Migrants from the former Soviet Union with Alcohol or Drug Problems in Germany]. / Versorgungsvorstellungen von Migranten aus der früheren Sowjetunion mit Alkohol- oder Drogenproblemen in Deutschland.

OBJECTIVE: Which representations of care can be found in migrants with alcohol or drug problems from the former Soviet Union? How do they correspond with views in the care system? METHODS: Episodic interviews with 46 migrants, expert interviews with 33 service providers; analysis with thematic coding. RESULTS: For migrants and experts holistic care is important, which include spiritual-religious components but are also control-oriented. CONCLUSION: The cultural specificity of migrants' care representations should be acknowledged by the health care system much more.

Chronic liver disease--an increasing problem: a study of hospital admission and mortality rates in England, 1979-2005, with particular reference to alcoholic liver disease.

AIMS: To determine time trends in hospital admissions for chronic liver disease in England between 1989/1990 and 2002/2003, mortality rates in England and Wales between 1979 and 2005, and the influence of alcohol-related disease on these trends. METHODS: Hospital episode statistics for admissions in England were obtained from the Information Center for Health and Social Care and mortality data for England and Wales from the Office for National Statistics. RESULTS: Hospital admission rates for chronic liver disease increased by 71% in males and 43% in females over the study period. This increase was largely due to alcoholic liver disease, admission rates for which more than doubled between 1989/1990 and 2002/2003. While there was a smaller rise for chronic viral hepatitis B and C, admission rates declined for hepatitis A, autoimmune hepatitis, and primary biliary cirrhosis. Mortality rates for chronic liver disease more than doubled between 1979 and 2005. Two thirds of these deaths were attributable to alcohol-related liver disease in 2005. The highest rate of alcoholic liver disease mortality was in the 45-64 age group, and the largest percentage increase between 1979 and 2005 occurred in the 25-34 age group. CONCLUSIONS: Hospital admissions and mortality in England from chronic liver disease are increasing. The underlying reasons are complex, but alcohol-induced liver disease makes a major contribution. There are clear social and health implications if the trend continues and addressing alcohol-related liver disease should be a public health priority.

Comparison of drug abuse in Germany and China.

Drug abuse has a long, but also different history in Germany and China. The Opium War largely influenced the history of China in 19th century; however, China was once recognized as a drug-free nation for 3 decades from the 1950s to the 1980s. Drug abuse has spread quickly since re-emerging as a national problem in China in the late 1980s. The number of registered drug abusers increased from 70 000 in 1990 to more than 1 million by the end of 2005. In past decades, illicit drug trafficking and production have swept most provinces in China, and drug abuse has caused many problems for both abusers and the community. One major drug-related problem is the spread of HIV, which has caused major social and economic damage in China. Germany, the largest developed European country, also faces the drug and addiction problem. Germany has about 150 000 heroin addicts, for whom HIV/AIDS has become a serious threat since the mid 1980s. To control the drug problem, the German Government adopted the pAction Plan on Drugs and Addictionq in 2003; the China Central Government approved a similar regulation in the antidrug campaign in 2005. Germany has experience in reducing drug-related harm. The methadone maintenance treatment (MMT) program has run for more than 20 years and the public has become more tolerant of addicts. In 2003, China began the MMT program for controlling the spread of HIV/AIDS. It is necessary for China to learn from developed countries to acquire success in its antidrug campaign. In this review, we will go over the differences and similarities in drug abuse between Germany and China. The differences are related to history, population and economics, drug policy context, drug laws, HIV/hepatitis C virus infection, the MMT program and so on. These 2 nations have drug abuse problems with different histories and currently use different approaches to handle illicit drug marketing and use. The legal penalties for illicit drug offences reflect the social differences of these 2 nations with respect to the seriousness of particular types of crimes. The characteristics of the MMT program may also influence patterns of drug abuse in these 2 nations and China should improve the MMT program based on the successful model in Europe, the USA, and Australia. We recommend more dialogue and collaboration between Germany and China.

Body composition, gender, and illicit drug use in an urban cohort.

This cross-sectional study of adult (137 male, 128 female), urban, community dwelling users and nonusers of illicit drugs evaluated associations of demographic, medical, and drug factors with body composition. The population was 49% HIV-positive and 94% African-American. In multivariate analysis, there were no body composition differences among males based on drug use. Among females, the highest tertile of drug use had less fat (12.3 vs.19.9 kg, p = .01) and lower body mass index (21.9 vs. 25.1, p = .01) versus less frequent or nonusers. These data suggest a sex difference in body composition associated with drug use.

Hepatitis C for addiction professionals.

A disease whose reputation is often worse than its reality, hepatitis C is usually benign. Most infected individuals do not experience symptoms requiring treatment, and roughly half of those treated will become free of detectable virus for an extended, perhaps permanent, period. Moreover, a growing body of data suggests that drug users can attain successful treatment outcomes, even when not completely abstinent. Addiction professionals belong in the forefront of prevention and management of this disease. We can assist our patients by helping them stabilize their lifestyles, correcting misperceptions about the disease, teaching prevention and health maintenance, promoting access to diagnosis and treatment, monitoring for treatment side effects, and providing encouragement to remain in treatment.

Co-morbidity of infectious and addictive diseases in St. Petersburg and the Leningrad Region, Russia.

The Russian health care system is organized around specific diseases, with relatively little focus on integration across specialties to address co-morbidities. This organizational structure presents new challenges in the context of the recent epidemics of injection drug use (IDU) and HIV. This paper uses existing and new data to examine the prevalence of reported new cases of drug dependence (heroin) and HIV over time as well as associations between drug dependence and alcoholism, hepatitis B and C, and tuberculosis in the City of St. Petersburg and the Leningrad region. We found a sharp rise in reported cases of IDU beginning in 1991 and continuing until 2002/2003, followed by a sharp rise in newly reported cases of HIV. These rises were followed by a drop in new cases of HIV and drug addiction in 2002/2003 and a drop in the proportion of HIV-positive individuals with IDU as a risk factor. Infection with hepatitis B and C were common, especially among injection drug users (38 and 85%, respectively), but also in alcoholics (7 and 14%). Tuberculosis was more common in alcoholics (53%) than in persons with alcoholism and drug dependence (10%), or with drug dependence alone (4%). Though these data have many limitations, they clearly demonstrate that drug dependence and/or alcoholism, HIV, hepatitis, and tuberculosis frequently co-occur in St. Petersburg and the Leningrad Region. Prevention and treatment services across medical specialties should be integrated to address the wide range of issues that are associated with these co-morbidities.

Using latent class analysis to identify patterns of hepatitis C service provision in drug-free treatment programs in the U.S.

Hepatitis C virus (HCV) infection is a global health problem, and in many countries (including the U.S.), illicit drug users constitute the group at greatest risk for contracting and transmitting HCV. Drug treatment programs are therefore unique sites of opportunity for providing medical care and support for many HCV infected individuals. This paper determines subtypes of a large sample of U.S. drug-free treatment programs (N=333) according to services they provide to patients with HCV infection, and examines the organizational and aggregate patient characteristics of programs in these subtypes. A latent class analysis identified four subtypes of HCV service provision: a "Most Comprehensive Services" class (13% of the sample), a "Comprehensive Off-Site Medical Services" class (54%), a "Medical Monitoring Services" class (8%) and a "Minimal Services" class (25%). "Comprehensive" services class programs were less likely to be outpatient and private for profit than those in the other two classes. It is of concern that so many programs belong to the "Minimal Services" class, especially because some of these programs serve many injection drug users. "Minimal Services" class programs in the U.S. need to innovate services so that their HCV infected patients can get the medical and support care they need. Similar analyses in other countries can inform their policy makers about the capacity of their drug treatment programs to provide support to their HCV infected patients.

Buprenorphine and methadone in the treatment of opioid dependence: methods and design of the COBRA study.

Buprenorphine and methadone are the two established substitution drugs licensed in many countries for the treatment of opioid dependence. Little is known, however, about how these two drugs are applied and how they work in clinical practice. In this paper we present the aims, methods, design and sampling issues of a collaborative multi-stage epidemiological study (COBRA) to address these issues. Based on a nationally representative sample of substitution physicians, the study is designed as an observational, naturalistic study, consisting of three major parts. The first part was a national survey of substitution doctors (prestudy, n = 379 doctors). The second part was a cross-sectional study (n = 223 doctors), which consisted of a target-week assessment of 2,694 consecutive patients to determine (a) the severity and problem profiles and treatment targets; (b) the choice and dosage scheme of the substitution drug; (c) past and current interventions, including treatment of comorbid hepatitis C; and (d) cross-sectional differences between the two drugs with regard to comorbidity, clinical course, acceptance/compliance and social integration. The third part consists of a prospective-longitudinal cohort study of 48 methadone-treated and 48 buprenorphine-treated patients. The cohort is followed up over a period of 12 months to investigate whether course and outcome of the patients differ by type or treatment received in terms of clinical, psychosocial, pharmaco-economic and other related measures. The response rate among substitution doctors was 57.1%; that among eligible patients was 71.7%. Comparisons with the federal registers reveal that the final samples of doctors and patients may be considered nationally representative with regard to regional distribution, training, type of setting as well as the frequency of patients treated with buprenorphine or methadone. The COBRA study provides a unique comprehensive database, informing about the natural allocation and intervention processes in routine care and about the course and outcome of patients treated with buprenorphine or methadone.

[The legal and occupational health aspects of B and C type viral hepatitis]. / A hepatitis B-vírus- es a hepatitis C-vírus-fertozés jogi es foglalkozás-egészségügyi vonatkozásai.

INTRODUCTION: Viral hepatitis is a problem of population health. Recent data show an estimated number of 400 million patients infected with hepatitis B and 170 million with hepatitis C virus in the world. The prevalence of HBV infected patients is estimated to 50000, the prevalence of the HCV patients to 70,000 in Hungary. AIMS: The authors report the legal and occupational health aspects of viral hepatitis. The knowledge of these facts could help both the patients and doctors. This paper is on the employment, occupational restrictions of the infected patients, the legal aspects of the discrimination and the vaccination. The authors report the knowledge, rules and restrictions relating to health service employees in a separate subchapter. They call the attention to the occupational health aspects in relation to the infected patients and health service employees from the point of view of the occupational health specialist, the commissioner responsible for safeguarding the patients' interest and the specialist attending the infected patients.

Outpatient drug treatment program directors' hepatitis C-related beliefs and their relationship to the provision of HCV services.

The hepatitis C virus (HCV) continues to penetrate populations within the United States, especially within the drug-abusing population. Therefore, drug users need access to HCV testing and medical care, and drug treatment programs are well situated to provide these services. Because directors of these programs are gatekeepers who can influence decisions about service provision, their beliefs about the value of providing particular services for drug treatment program patients are of considerable importance. Directors of 121 outpatient drug treatment programs throughout the United States responded to an in-depth telephone survey that included questions on their beliefs about providing HCV services in drug treatment programs. We constructed an eight-item scale to examine these beliefs and investigated the relationship between them and the actual HCV services offered. Overall, directors were moderately supportive of the provision of HCV medical services (on-site or through referral) during drug treatment. Our findings indicate that there is a positive significant relationship between director's beliefs and the provision of HCV antibody testing, follow-up testing, and the provision of HCV medication.

A 25-year follow-up study of drug addicts hospitalised for acute hepatitis: present and past morbidity.

The aim of the study was to investigate present and past morbidity in drug addicts, 25 years after hospitalisation for acute hepatitis B or hepatitis nonA-nonB. The hospital records for 214 consecutively admitted patients were analysed, and a follow-up study on 66 of the 144 patients still alive was performed. At follow-up, 1 of 54 (1.8%) hepatitis B patients was still HBsAg positive. Twelve patients originally diagnosed as hepatitis nonA-nonB were all among 54 found to be anti-hepatitis C virus (anti-HCV) positive, and the total anti-HCV prevalence was 81.8%. Twelve (22.2%) of the HCV cases were unknown before the follow-up examination. Four (6.1%) participants were anti-human immunodeficiency virus positive, only 1 was on antiretroviral therapy, and none had developed AIDS. Other chronic somatic diseases were a minor problem, whereas drug users reported skin infections as a frequent complication. Forty-three patients (65%) had abandoned addictive drugs since the hospital stay. Serious mental disorders were reported by 19 patients (28.8%), and 17 (25.8%) regarded themselves as present (9) and former (8) compulsive alcohol drinkers. A large proportion of the participants were granted disability pension (39%), a majority because of psychiatric disorders, drug and alcohol abuse.
