Prevalence of HIV, hepatitis B and associated risk behaviours in clients of a needle-exchange in central London.

In order to determine the prevalence of risk behaviour for, and antibodies to HIV and hepatitis B in clients of a needle-exchange scheme in central London we employed an anonymous, self-administered questionnaire along with salivary antibody testing by immunoglobulin (Ig) G antibody capture immunoassay. Two hundred and thirty-two subjects (193 men, 39 women; median age 32) participated; a response rate of 89%. Clients were long-term, frequent injectors. Lending used equipment at any time was reported by 55%, and borrowing by 52%. Of those who had shared needles and syringes during the last year, the majority had lent to, or borrowed from, one person only (53 and 55%, respectively). Younger clients (less than 29 years of age) reported more recent sharing than older clients (greater than 30 years of age). Five out of 211 (2.4%) samples tested for anti-HIV were positive. One hundred and eleven out of 199 (56%) samples were positive for anti-hepatitis B core (HBc). In this population of needle-exchange attenders there is no evidence of further spread of HIV, and a low prevalence of HIV infection appears to have been sustained. However, the high prevalence of anti-HBc provides evidence of previous risk behaviour and so constant vigilance is necessary if further viral spread is to be avoided. This study has established an acceptable method for the anonymous surveillance of current risk behaviour and salivary antibodies to HIV and hepatitis B virus (HBV) in a drug-using population.

Needle-exchange in central London: operating philosophy and communication strategies.

Despite a large number of needle-exchange schemes in the U.K., there are few accounts of how particular agencies attract injecting drug users. This paper describes a busy scheme in London, the take-up of services by clients, and the operating philosophy of the staff. From November 1987 to October 1988 The Exchange saw a mean of 257 clients per month, making an average three visits per client each month. An average of 8,950 needles and syringes were dispensed and 6,918 returned monthly, giving an average return rate of 77%. The Exchange also served as a referral agency to clients; 533 referrals were made, 63.4% of which were to drug and non-medical services, 36.6% to health services, and 9.2% to HIV services. To account for the take-up of services the paper describes The Exchange's open access policy, the staff's communication strategies and their adoption of the philosophy of harm-minimization in relation to injecting drug use. It is argued that these must be seen as integral to needle-exchange if it is to succeed as a comprehensive service.

Evaluation of needle exchange in central London: behaviour change and anti-HIV status over one year.

From November 1987 to October 1988, numbers of clients, visits made and syringes dispensed and returned were monitored at the needle exchange of the Middlesex Hospital, London, UK. A sample of clients were interviewed 1 month after entry to the scheme and again 3 months later to evaluate changes in injecting and sexual risk behaviours for HIV infection. Clients were asked to donate saliva for anti-HIV immunoglobulin G (IgG) antibody capture radioimmunoassay (GACRIA). The rate of lending and borrowing used injecting equipment fell, both compared with rates prior to entry to the scheme and during the period of study. Frequency of injecting did not increase and there was reduced incidence of abscesses. There was a highly significant correlation between multiple sexual partners and condom use and a reduction in the proportion of clients with multiple partners. On entry to the study, seven out of 121 (6%) clients were anti-HIV positive; after 3 months, a further two clients tested were found to be anti-HIV positive. Anti-HIV positivity prevalence for the year of study was nine out of 121 (7%). The scheme attracts clients, reduces injecting-related risk for HIV infection and has high equipment return rates. Saliva testing is acceptable to clients. Continued monitoring of anti-HIV in saliva is indicated.

Insomnia: nonpharmacologic management by private practice physicians.

We report a survey investigation on the perceived value of behavioral assessment and the use of nonpharmacologic treatment of insomnia by 159 physicians in private practice in Davidson County, Tennessee. They generally attributed limited value to behavioral assessment, and reported infrequent use of nonpharmacologic treatment. However, the more patients the physicians saw with insomnia as the chief symptom, the more they tended to value behavioral assessment and other diagnostic procedures. Endorsement of behavioral assessment and all other diagnostic practices was in turn related to the use of behavioral treatment techniques. We suggest that a lack of awareness of the value of alternative assessment and treatment strategies may account for physicians' limited use of nonpharmacologic approaches to this common yet frequently serious medical problem.
