Hepatitis C among drug users: consensus guidelines on management in general practice

Hepatitis C virus infection in Irish drug users and prisoners - a scoping review

BACKGROUND

Hepatitis C infection is a major public health concern globally. In Ireland, like other European countries, people who use drugs (PWUD) and prisoners carry a larger HCV disease burden than the general population. Recent advances in HCV management have made HCV elimination across Europe a realistic goal. Engaging these two marginalised and underserved populations remains a challenge. The aim of this review was to map key findings and identify gaps in the literature (published and unpublished) on HCV infection in Irish PWUD and prisoners.

METHODS

A scoping review guided by the methodological framework set out by Levac and colleagues (based on previous work by Arksey & O'Malley).

RESULTS

A total of 58 studies were identified and divided into the following categories; Epidemiology, Guidelines and Policy, Treatment Outcomes, HCV-related Health Issues and qualitative research reporting on Patients' and Health Providers' Experiences. This review identified significantly higher rates of HCV infection among Irish prisoners and PWUD than the general population. There are high levels of undiagnosed and untreated HCV infection in both groups. There is poor engagement by Irish PWUD with HCV services and barriers have been identified. Prison hepatology nurse services have a positive impact on treatment uptake and outcomes. Identified gaps in the literature include; lack of accurate epidemiological data on incident infection, untreated chronic HCV infection particularly in PWUD living outside Dublin and those not engaged with OST.

CONCLUSION

Ireland like other European countries has high levels of undiagnosed and untreated HCV infection. Collecting, synthesising and identifying gaps in the available literature is timely and will inform national HCV screening, treatment and prevention strategies.

Problem alcohol use among problem drug users: development and content of clinical guidelines for general practice

BACKGROUND

Problem alcohol use is common and associated with considerable adverse outcomes among patients who attend primary care in Ireland and other European countries for opiate substitution treatment.

AIMS

This paper aims to describe the development and content of clinical guidelines for the management of problem alcohol use among this population.

METHODS

The guidelines were developed in three stages: (1) identification of key stakeholders, (2) development of evidence-based draft guidelines, and (3) determination of a modified 'Delphi-facilitated' consensus among the group members.

RESULTS

The guidelines incorporate advice for physicians on all aspects of care, including (1) definition of problem alcohol use among problem drug users, (2) alcohol screening, (3) brief intervention, and (4) subsequent management of patients with alcohol dependence.

CONCLUSIONS

Primary care has an important role to play in the care of problem alcohol use among problem drug users, especially opiate substitution patients. Further research on strategies to inform the implementation of these guidelines is a priority.

Criteria for Referring Patients With Outpatient Gastroenterological Disease for Specialist Consultation: A Review of the Literature

Background

Demands on gastroenterology are growing, as a result of the high prevalence of digestive diseases, the impact of colon cancer screening programs and an aging population. Prioritizing referrals to gastroenterology would assist in managing wait times. Our objectives were (1) to assess whether there were consistent criteria to guide referrals from family physicians for gastroenterological outpatient consultation and (2) to determine if there were different levels of urgency or priority in referral criteria.

Methods

We conducted a scoping review, searching Medline, Embase and Cochrane databases from 1997 to 2009, using the terms referral, triage, consultation and at least one from a list of gastroenterology-specific search terms. Of 2978 initial results, 51 papers were retrieved, and 20 were retained after review by two reviewers. Additional publications were identified through hand searches of retained papers, website searches and nomination by a panel of specialists.

Results

Thirty-four papers, reports or websites were retained. No referral criteria covered the spectrum of disorders that might be referred by family physicians to gastroenterologists. Criteria for referral were most commonly listed for suspected colorectal cancer, followed by suspected upper GI cancer, hepatitis, and functional disorders.

Conclusions

A clinical panel comprised of gastroenterologists and primary care providers, informed by this literature review, are completing the work of formulating a Gastroenterology Priority Referral Score, and plan to test the reliability and validity of the tool for determining the relative urgency for referral from primary care to gastroenterology.

Health of the homeless in Dublin: has anything changed in the context of Ireland's economic boom?

BACKGROUND

In the context of the Irish economic boom we assessed the health, service utilisation and risk behaviour of homeless people in north Dublin city and compared findings with a 1997 study.

METHODS

A census of homeless adults in north Dublin city was conducted in 2005 using an adapted interviewer-administered questionnaire from the 1997 study.

RESULTS

A total of 363 (70%) of the target population participated. Compared to 1997 the population was younger (81% versus 70% under 45 years, P < 0.01) with a higher proportion of women (39% versus 29%, P < 0.05) and long-term homeless (66% versus 44%, P < 0.001). Drug misuse superseded alcohol as the main addiction with a doubling of the proportion reporting past or current drug use (64% versus 32%, P < 0.001). The prevalence of comparable physical chronic conditions was largely unchanged while depression (51% versus 35%, P < 0.01) and anxiety (42% versus 32%, P < 0.05) had increased. There were high rates of blood-borne infections, such as HIV (6%), hepatitis B (5%) and hepatitis C (36%) in 2005 and dental problems (53%) all of which can be associated with drug use. Access to free healthcare had not increased. Similar proportions reported not having medical cards (40% versus 45% NS). Homeless people continued to have higher usage of secondary care services than the general population.

CONCLUSIONS

This study shows a changing disease profile among the homeless population consistent with a growing drug using population. It confirms that the homeless population in Dublin in terms of health remain excluded from the benefits of an economic boom despite a government policy aimed at redressing social inclusion.

Management of hepatitis C among drug users attending general practice in Ireland: baseline data from the Dublin area hepatitis C in general practice initiative

OBJECTIVE

In Ireland, general practice is increasingly providing long-term care for injecting drug users, 62-81% of whom are infected with hepatitis C (HCV). Clinical guidelines for the management of HCV among drug users have recently been developed in Ireland, and this study aimed to describe HCV care among drug users attending general practice in the greater Dublin area, prior to the implementation of the clinical practice guidelines.

METHODS

The clinical records of 196 patients attending 25 general practices in the Eastern Regional Health Authority area of Ireland for methadone maintenance treatment were examined on site and anonymized data collected on HCV care processes.

RESULTS

Patients had been attending general practice for methadone maintenance treatment for a mean of 30.7 months, 72% were male and 51% had provided a urine sample testing positive for metabolites of drugs of abuse other than methadone in the previous 3 months. There was evidence that 77%, 69% and 60% had been screened for HCV, human immunodeficiency virus (HIV) and hepatitis B (HBV), respectively. Among those who had been tested, the prevalence of HCV, HIV and HBV infection was 69%, 10% and 11%, respectively. Of those known to be HCV positive, 36 (35%) had been tested for HCV-RNA (29 testing positive), 31 (30%) had been referred to a hepatology clinic, 24 (23%) had attended a clinic, 13 (13%) had a liver biopsy performed and three (3%) had started treatment for HCV.

CONCLUSION

While the majority of patients have been screened for blood-borne viruses, a minority of those infected with HCV have had subsequent investigations or treatment. New interventions to facilitate optimum care in this regard need to be considered.

Guidelines for the management of hepatitis C in general practice: a semi-qualitative interview survey of GPs’ views regarding content and implementation

BACKGROUND

Hepatitis C is a common infection among people who attend GPs for methadone maintenance treatment.

AIM

To determine the views of GPs towards clinical guidelines for the management of hepatitis C among current or former injecting drug users in advance of their implementation.

METHODS

A purposive sample of 14 GPs (10% of the total prescribing methadone at the time the guidelines were developed) was invited to review a pre-publication draft of the guidelines and interviewed regarding content, presentation, perceived barriers to implementation and suggested interventions to facilitate effective implementation of the guidelines.

RESULTS

GPs indicated the guidelines were useful but suggested aspects of presentation should be clarified. Organisational issues were identified as the principal barriers to effective implementation, with the provision of additional nursing support the principal intervention suggested to facilitate implementation.

CONCLUSIONS

Interviewing intended recipients may be an important step in ensuring clinical practice guidelines are effectively implemented.
