Factors associated with injecting risk behaviour among serial community-wide samples of injecting drug users in Glasgow 1990-94: implications for control and prevention of blood-borne viruses.

AIMS: To examine the association between recipient-sharing of needles and syringes and demographic characteristics, injecting behaviour and needle and syringe exchange utilisation. DESIGN: Self-report data from serial cross-sectional surveys. SETTING: Multiple street, needle and syringe exchange and drug treatment sites throughout Glasgow. PARTICIPANTS: 2576 current injecting drug users (IDUs) recruited during 1990-94. FINDINGS: In the multiple logistic regression analysis, a significantly lower level of recipient-sharing was associated with respondents who resided within 1 mile of a needle and syringe exchange compared to those who lived further away (adjusted OR 1.3; 95% CI 1.0-1.6), and by IDUs who reported obtaining either 6-15, 16-30, or > 30 sterile needles and syringes in an average week from a needle exchange and/or pharmacist (adjusted ORs 0.55, 0.34, 0.25; 95% CIs 0.3-0.9, 0.2-0.6 and 0.2-0.4, respectively) compared to those who obtained no sterile equipment from these sources. Recipient-sharing of needles and syringes in the previous 6 months reduced significantly between 1990 (43%) and 1991-94 (27-33%) (p < 0.0001); this decline was not explained by needle and syringe exchange utilization, suggesting that additional factors were influencing behavioural change at that time. CONCLUSION: Our data indicate that improving injectors' convenience of access to exchange facilities and increasing the numbers of sterile needles and syringes available to them is likely to result in further reductions in recipient-sharing, and thus the potential for blood-borne virus transmission, among IDUs.

One-year follow-up of opiate injectors treated with oral methadone in a GP-centred programme.

AIMS: To examine changes in drug-related behaviour in opiate-dependent injectors treated with oral methadone, in a shared care scheme where consumption of the daily dose is usually supervised by a community pharmacist. DESIGN: One-year cohort study. SETTING: Recruitment from the main routes into methadone prescribing in Glasgow during 1996: General Practitioner Drug Misuse Clinic Scheme and the Drug Problem Service. PARTICIPANTS: Current opiate injectors entering methadone treatment. FINDINGS: Among the 204 injectors recruited, 148 (73%) were re-interviewed at 6 months and 118 (58%) at both 6 and 12 months. Twenty-nine per cent of the cohort remained continuously on methadone for 12 months. In that group, over the 12-month period, self-reported daily opiate injecting reduced from 78% to 2%; overdose in the previous 6 months from 24% to 2%; mean daily drug spend from 50 Pounds to 4 Pounds; and mean monthly number of acquisitive crimes reduced from 13 to three. Assuming participants lost to follow-up were unchanged, significant improvements in the total cohort were seen in daily opiate injecting (from 80% at recruitment to 43% at 12 months), overdose (from 27% to 15%), mean daily drug spend (from 63 Pounds to 38 Pounds) and mean monthly number of acquisitive crimes (from 18 to 11). Discontinuation of treatment was mainly due to imprisonment (39%) or sanctions by the prescriber (33%). CONCLUSION: Treatment of opiate-dependent drug injectors with methadone in a community-wide general practitioner-centred scheme, with supervised daily consumption, was associated with major beneficial change for a substantial proportion of patients.

A lasting public health response to an outbreak of HIV infection in a Scottish prison?

Between April and June 1993, 8 cases of acute clinical hepatitis B infection and 2 seroconversions to HIV infection were detected among drug injecting inmates of HM Prison Glenochil in Scotland. To prevent the further spread of infection, an initiative which involved counselling and voluntary attributable HIV testing was conducted over a 10-day period commencing at the end of June. A team of 18 counsellors and phlebotomists was brought together rapidly as part of a unique organizational exercise in the field of public health. Fourteen cases of HIV infection were identified of which 13 were almost certainly infected in Glenochil. Following the exercise, a range of harm reduction measures for injecting prisoners was introduced; these included the availability of hepatitis B vaccine, provision of bleach tablets which could be used to clean injecting equipment, a methadone detoxification programme, increased training for prison officers and improved access to drug and harm minimization counselling for inmates. By mid-1996 all these measures had been sustained and several could be found in many other prisons throughout Scotland. Follow-up investigations showed no evidence of epidemic spread of HIV during the 12 months after the initiative. While the frequency of injecting and needle/syringe sharing may have decreased over the last 3 years, these activities are still being reported and it is highly likely that transmissions of bloodborne infections, in particular hepatitis C, continue to occur. The surveillance and prevention of infections associated with injecting drug use in the prison setting remain a high public health priority.

The Sexual Health Help Centre: a service for young people.

BACKGROUND: The Sexual Health Help Centre (SHHC) was opened in 1995 to provide treatment, advice and information on family planning and sexual health issues for young people under the age of 20 years, in a way which is open and non-threatening. This paper describes an evaluation conducted during the first 9 months of service operation. METHODS: Young people's experience of the SHHC were elicited, and compared with their experiences of conventional family planning services in Glasgow. RESULTS: The SHHC has been successful in attracting young people for help with family planning problems and provides a more acceptable environment than conventional family planning services. However, a greater number of young men and young people under the age of 16 should be encouraged to attend the service. CONCLUSION: Young people are more likely to visit family planning services if they are offered a wide range of family planning and sexual health services in a non-judgmental, non-threatening environment.

Injecting-related harm and treatment-seeking behaviour among injecting drug users.

AIMS: This study aims to identify the physical harm associated with injecting drug use and examine the treatment-seeking behaviour of injecting drug users (IDUs). Specific attention is given to the factors associated with presentation and non-presentation of injecting-related problems. DESIGN: Participants were interviewed by research staff using a semi-structured questionnaire, then physically examined by a medical team. SETTING: Needles exchanges in Glasgow. PARTICIPANTS: One hundred and twelve injecting drug users. FINDINGS: Respondents' accounts of their current injecting-related problems were found to be consistent with the clinician's findings, suggesting that IDUs are able to self-diagnose injecting-related harm. However, almost three-quarters had not sought help for these problems. Qualitative data suggest the main reasons for non-presentation, or delayed presentation, of injecting-related problems are normalization of injecting-related harm and a reluctance to attend available services. Almost half of those seeking treatment for injecting-related problems did so during an emergency or crisis. CONCLUSIONS: Low threshold services, such as needle exchanges, may have to take a more proactive stance to encourage injectors to present with injecting-related problems. This may help reduce injecting-related harms, especially the resulting medical complications, which would in turn relieve the pressure on other services such as hospital Accident and Emergency Departments.

Management of HIV infected health care workers: lessons from three cases.

Three cases in which doctors in Glasgow were diagnosed as having HIV infection were all handled differently in relation to telling patients and the media. In the first patients were not told because the doctor had been doing administrative work and there was thought to be no risk to patients; although the media did report the case, it accepted the assurances given. In the second case, where a doctor had done many jobs in different specialties and places, the media identified the doctor before most patients had been informed: most calls to the helpline subsequently set up by the health authority were from patients who had not been treated by this doctor. This episode, however, allowed the incident team to be prepared for the next case, enabling the helpline to be established swiftly. In this case the doctor voluntarily identified himself, and this served to allay public fears and reduce the number of inappropriate calls to the helpline.

A primary health care service for Glasgow street sex workers--6 years experience of the "drop-in centre', 1989-1994.

In Glasgow, a health and social care centre opened in 1988 principally to facilitate HIV prevention among street prostitutes, most of whom are injecting drug users. During 1992 to 1994, 551 women made 17,554 visits to the medical room which is functional 5 nights per week. The mean age of the sex workers was 26 years (range 15 to 62) and 89% injected drugs. Fifty-five per cent of the attendances were for needle/syringe exchange only whilst the remainder involved other health care provision. Common presenting problems included abscesses, burns and venous thromboses, reflecting the high proportion of sex workers who injected drugs. Most women always used condoms for penetrative commercial sex and symptomatic sexually transmitted disease was seen infrequently. In addition to the provision of injecting equipment and condoms, other key prevention activities included Hepatitis B vaccination and cervical screening. The prevalence of HIV infection amongst the women remains under 5% and most seropositives were known to be infected before the Centre opened. This initiative shows that if multidisciplinary health and social services are provided to street sex workers at a time and place convenient to their work, the benefits are considerable.

Theatre in AIDS education--a controlled study.

Theatre is now widely used in HIV and AIDS education for young people. However, research concerning its effectiveness has largely been conducted without using comparison or control groups and there is little evidence that other types of intervention are more or less effective. The present study was designed to measure the effects of a theatre production on HIV knowledge, attitudes and risk behaviour of young people compared with that of a standard health education seminar which used group work techniques. Both interventions were designed for young people between the ages of 12 and 18 and held in 10 youth projects in socially deprived areas of Glasgow. Five youth projects were randomly assigned to each intervention. All participants were asked to complete a self-administered HIV knowledge, attitude and behavioural questionnaire immediately before and after the event and 2 months later. Research focus groups were also used. A total of 35 young people attending the standard seminars completed three self-administered questionnaires, and 18 participated in all three focus groups. Forty-two young people attending the theatre performances completed three self-administered questionnaires and 16 participated in all three focus groups. There was little impact on the knowledge and attitudes of either audience, although there was some evidence of attitudinal change among those exposed to the health education discussion session. More of the theatre group reported a behavioural change 2 months after attending the play but only in relation to buying and carrying condoms. It is uncertain whether this led to safer sex practices. This study does not support the view that theatre in AIDS education has a significant impact on HIV knowledge, attitudes and risk behaviour.

Outbreak of HIV infection in a Scottish prison.

OBJECTIVE--To investigate the possible spread of HIV infection and its route of transmission among prison inmates. DESIGN--In response to an outbreak of acute clinical hepatitis B and two seroconversions to HIV infection, counselling and testing for HIV were offered to all inmates over a two week period in July 1993. Information was sought about drug injecting, sexual behaviour, and previous HIV testing. SETTING--HM Prison Glenochil in Scotland. SUBJECTS--Adult male prisoners. MAIN OUTCOME MEASURES--Uptake of HIV counselling and testing; occurrence and mode of HIV transmission within the prison. RESULTS--Of a total 378 inmates, 227 (60%) were counselled and 162 (43%) tested for HIV. Twelve (7%) of those tested were positive for antibody to HIV. One third (76) of those counselled had injected drugs at some time, of whom 33 (43%) had injected in Glenochil; all 12 seropositive men belonged to this latter group. Thirty two of these 33 had shared needles and syringes in the prison. A further two inmates who injected in the prison were diagnosed as positive for HIV two months previously. Evidence based on sequential results and time of entry into prison indicated that eight transmissions definitely occurred within prison in the first half of 1993. CONCLUSION--This is the first report of an outbreak of HIV infection occurring within a prison. Restricted access to injecting equipment resulted in random sharing and placed injectors at high risk of becoming infected with HIV. Measures to prevent further spread of infection among prison injectors are urgently required.
