Evaluation of general practice computer templates. Lessons from a pilot randomised controlled trial.

We conducted a pilot randomised trial of computerised templates for the management of asthma and diabetes in general practice in six general practices in North London. Uptake of the guidelines by general practitioners and practice nurses was assessed using qualitative (semi-structured interviews designed to assess the users' views) and quantitative (change in use of the template during the study period) outcome measures. The practice nurses used the templates frequently but general practitioners rarely used them. Several reasons were offered for non-use of the templates, such as the length of the template and non-involvement in the care of asthma or diabetes. Despite this, however, health professionals were favourably disposed to the use of templates for general clinical care. Pilot investigations of computerised templates are best achieved by observational or quasi-experimental methods rather than a randomised controlled trial. The use of both qualitative and quantitative methods in this study allowed exploration of the barriers to use of computers.

Prostitution and risk of HIV: female prostitutes in London.

OBJECTIVE: To measure the prevalence of HIV and to describe established risk factors in female prostitutes. DESIGN: A cross sectional survey. SETTING: A genitourinary medicine clinic, streets, and magistrates' courts in London. SUBJECTS: 280 female prostitutes recruited between April 1989 and August 1991. MAIN OUTCOME MEASURES: Infection with HIV-1, reported risk behaviours, and prevalence of sexually transmitted infections. RESULTS: 228 of the women had HIV tests, and two (0.9% (95% confidence interval 0% to 2.1%)) were infected with HIV-1. Reported use of condoms was high for commercial clients and low for non-paying partners: 98% (251/255) of women used condoms with all clients and 12% (25/207) with non-paying partners for vaginal intercourse. Twenty two women were current or past injecting drug users. Of the 193 women examined for sexually transmitted infections, 27 had an acute infection (gonorrhoea, chlamydia, trichomonas, or primary genital herpes) at the time of interview. Infection was associated with younger age and increasing numbers of non-paying sexual partners, but not with duration of prostitution, numbers of clients, or reports of condom failures. When age and numbers of non-paying partners were analysed by logistic regression they remained significantly associated with sexually transmitted infections. CONCLUSIONS: A large and diverse sample of prostitutes had a low prevalence of infection with HIV and high levels of use of condoms in commercial sex. There was a significant risk of other sexually transmitted infections associated with prostitutes' non-commercial sexual relationships, in which unprotected sex is common. Interventions to reduce the risk of sexually transmitted infections in prostitutes should address both commercial and non-commercial sexual partnerships.

Comparison of ofloxacin with doxycycline in the treatment of non-gonococcal urethritis and cervical chlamydial infection.

The efficacy of ofloxacin was compared with that of doxycycline in the treatment of non-gonococcal urethritis (NGU) and cervical chlamydial infection in an open randomized study. In total, 182 men and 100 women were enrolled: 92 men and 50 women received ofloxacin at a dose of 400 mg once daily for seven days, and 90 men and 50 women received doxycycline at a dose of 100 mg twice daily for seven days. All women and 42 men, that is 29 men in the ofloxacin group (32%) and 13 in the doxycycline group (14%) were chlamydia-positive on entry into the study. Patients were reviewed on completion of the treatment course (day 8) and two weeks later (day 22). Clinical cure rates for NGU in assessable patients in each treatment group were similar; 73% in the ofloxacin group and 63% in the doxycycline group at day 8, and 70% and 90% in the respective treatment groups on study completion. Repeat tests for chlamydiae were negative for all male and female patients at both day 8 and day 22. Both ofloxacin and doxycycline were well tolerated. We conclude that ofloxacin given at a dose of 400 mg once daily for seven days is a safe and effective alternative treatment for NGU and cervical chlamydial infection.

An update on HIV-testing at a London sexually transmitted diseases clinic: long-term impact of the AIDS media campaigns.

Trends in the number of tests for HIV-1 antibody at a London sexually transmitted diseases clinic showed substantial changes between September 1985 and June 1988. From an average of 100 tests per month between September 1985 and August 1986, the average increased to 365 tests per month for September 1986 to August 1987. This levelled off at 243 tests per month between September 1987 and June 1988. The average number of positive tests per month between September 1985 and June 1988 remained constant, though the number of seropositive tests in females increased. Male and female populations displayed similar temporal patterns. The greatest increase was seen in the tests generated by heterosexual males and females with no other risk factors. This group generated 42% of the 8012 tests performed during the study period. The Clinic's catchment area predominantly included London and surrounding areas and temporal patterns were similar for residents from each of the Thames Regions. The temporal patterns observed coincided with periods of increased media attention on HIV infection/AIDS and involved campaigns by the popular press, television, Department of Health Education Authority. The increase in tests during the time of maximum media exposure, the subsequent plateau at a level substantially higher compared with the period preceding the media campaigns and the large increase in heterosexual males and females tested, all suggest that the campaigns have contributed to increasing awareness of HIV infection/AIDS as a major contemporary public health problem.

Risk factors for HIV-1 infection in a British population: lessons from a London sexually transmitted diseases clinic.

Between September 1985 and June 1988, 6923 people (4550 men and 2373 women) were tested for HIV-1 antibodies at a sexually transmitted disease clinic, London, UK. Of the 6923 individuals tested, 558 (8%) were seropositive, of whom 523 (94%) were men and 35 (6%) women. Of the seropositives, 84% were homosexual or bisexual men, 5% were intravenous drug users, 4% were heterosexual contacts of HIV seropositives, 4% had multiple risk factors, 2% were heterosexual contacts of central African partners and 1% were heterosexuals with no other risk factors. This prevalence pattern conforms to that observed in other industrialized nations. For the women, heterosexual intercourse with an HIV-infected partner, intravenous drug use and heterosexual contact with a partner from central Africa were the main risk factors for infection. The important risk factors among the men were heterosexual contact with an HIV-seropositive partner, being homosexual or bisexual, intravenous drug use and heterosexual contact with a resident from central Africa. heterosexual and homosexual transmission were implicated as the main routes for viral spread in this British population.

Prostitutes can help prevent the transmission of HIV.

Social stigma and misconceptions about prostitution are barriers to promoting sexual health. This paper discusses the use of public health interventions to break down these barriers. It also attempts to offer some understanding of female prostitutes in particular and explain why they should not be driven underground.

Knowledge and attitudes to prescribed drugs in young and elderly patients.

Increasing patient knowledge of drug therapy is said to improve compliance and may reduce adverse drug reactions. We assessed patient knowledge of prescribed drugs in fifty patients attending a hypertension clinic [outpatients] and in elderly patients on admission to (n = 129) and on discharge from (n = 100) an acute geriatric assessment unit. We found that 88% of outpatients, 40% of elderly admissions, and 41% of elderly discharges knew the indications for their therapy; only 40% of outpatients, 8% of elderly admissions and 12% of elderly discharges could name their medications. Patients said that their information came principally from the prescribing doctor. In a further study we assessed doctor, nurse, young and elderly patients' ability to discriminate between commonly prescribed white tablets. Errors were made by the doctors on 25% occasions, nurses on 40% occasions and patients on 61% occasions. Young patients made errors 67% of the time and elderly patients 55% of the time. These studies indicate that both inpatients and outpatients, both young and elderly have poor knowledge of their medications. In addition, many commonly prescribed drugs are not easily distinguishable by patient, prescriber or drug administrator. We conclude that there is a need to improve knowledge both in patients and in prescribers. We suggest that prescribers should consider the colour and shape of medications prescribed concurrently as many "little white tablets" are difficult to tell apart.
