Capacity building for international tuberculosis control through operations research training.

SETTING: In resource-poor countries, few tuberculosis (TB) program staff at the national, provincial, and even district levels have the basic analytical and epidemiological skills necessary for collecting and analyzing quality data pertaining to national TB control program (NTP) improvements. This includes setting program priorities, operations planning, and implementing and evaluating program activities. OBJECTIVES: To present a model course for building capacity in basic epidemiology and operations research (OR). DESIGN: A combination of didactic lectures and applied field exercises were used to achieve the main objectives of the 6-day OR course. These were to increase the understanding of quantitative and qualitative research concepts, study design, and analytic methods, and to increase awareness of how these methods apply to the epidemiology and control of TB; and to demonstrate the potential uses of OR in answering practical questions on NTP effectiveness. As a final outcome, course participants develop OR proposals that are funded and later implemented. RESULTS: Since 1997, this OR course has been conducted nine times in five countries; 149 key NTP and laboratory staff have been trained in OR methods, and 44 OR protocols have been completed or are underway. CONCLUSION: This low-cost model course can be adapted to a wide range of public health issues.

A national disease registry moves beyond clinical impact, fostering measurable cost savings at the community hospital level.

National disease registries have existed for many years, and give hospitals and medical professionals centralized, disease-specific databases that can be used to study both treatment protocols and quality outcomes. To date, most efforts have focused on the quality management and clinical aspects of disease registries. However, Sierra Nevada Memorial Hospital, using the National Registry for Myocardial Infarction, recently concluded a study that identified and then attempted to quantify several positive financial effects on the hospital in terms of improved cost outcomes and resource management. The study concluded that activities that improve clinical outcomes (reduce mortality, morbidity, and complications) for acute myocardial infarction (AMI) patients can have a wide range of effects not only for the patients themselves, but also on the cost of care and the utilization of resources. The study discovered that these effects can be measured and expressed quantitatively or qualitatively. Consequently, improving the clinical quality of AMI patient care or reducing the costs of that care can be expected to produce enhanced value for health care consumers, providers, and the health care economy. Furthermore, it is highly likely that this principle would apply to many other kinds of disease registry programs when used to support quality improvement activities.

Basal cell carcinomas cause little handicap.

Basal cell carcinoma (BCC) is the most common type of skin cancer and the incidence of BCC is expected to rise, with increased demand on dermatology resources. Little is known of the effect on people's lives of having skin cancer. The aim of this study was to quantify the handicap caused gy basal cell carcinomas before and after therapy. Forty-four patients (22 males, mean age = 65 yrs, range = 35-81 yrs) with 48 BCCs were recruited and 37 patients completed the study. Each patient completed the UK Sickness Impact Profile (UKSIP) and the Dermatology Life Quality Index (DLQI) at the initial visit to the dermatology clinic, 1 week after treatment and 3 months after treatment. Lesions had been present for a mean of 25 months (range = 1-240 months), their mean diameter was 9.6mm (range = 3-35mm) and the sites were head and neck (79%), trunk (17%) and limbs (4%). There was no relationship between the quality of life score and size of lesion. Overall the scores at presentation were very low, rising 1 week after treatment and falling to below the initial scores at 3 months (mean UKSIP 0.4%, 0.7%, 0.13%; mean DLQI 5.3% 8.7%, 1.2%). BCCs cause little handicap. This may explain the delay in seeking medical attention and should be considered in planning public health education about BCCs.

Complement C6 and C7 DNA polymorphisms analysed by PCR in seven ethnic groups and characterisation of the C6 MspI RFLP.

Five polymorphisms in the C6 and C7 genes have been investigated in seven ethnic groups. The allele frequencies are broadly similar in most groups except C7 M/N which is monomorphic in our group of Africans, and C6 MspI and C7 S367T where the allele frequencies in African and Cape Coloured subjects are very different from the other ethnic groups. There is very little allelic association except between C6 A/B and C6 MspI. Seventeen of the 32 possible haplotypes have been observed, suggesting that much recombination has taken place. We describe a new method for the investigation of the MspI RFLP located in intron 3 of C6 (approximately 3 kbp 3' from exon 3 and 1.5 kbp 5' from exon 4) and its molecular basis, together with an improved method for the isolation of DNA from stored serum.

Removal of iron dextran by hemodialysis: an in vitro study.

Intravenous iron dextran is frequently prescribed for iron-deficient hemodialysis patients, a practice that has increased during the erythropoietin era. Whether iron dextran is removed by hemodialysis has been a concern, especially for high permeability membranes. The purpose of this in vitro study was to measure iron dextran clearance by nine different hemodialyzers (Fresenius F3, F8, and F80B; Baxter CF25, CA150, CA210, and CT190; Toray BK2.1P; and Hospal Filtral 16) representing six types of membranes (polysulfone, cuprophane, cellulose acetate, cellulose triacetate, polymethylmethacrylate, and polyacrylonitrile) and including membranes considered high efficiency and high flux. Clearances were assessed using a closed-loop, fixed-volume reservoir model. Absolute drug removal also was determined over the 30-minute experiments. Iron dextran clearance did not exceed 25 mL/min, and clearances also were minimal after a single automated reuse with glutaraldehyde sterilant. A maximum of 8% of iron dextran was removed during the experiment. We conclude that iron dextran clearance by the nine hemodialyzers studied was small or too low to be detected in this sensitive in vitro dialysis system and that adjusting dosing schedules is not needed.

HIV testing among injecting drug users in Glasgow.

The use of saliva rather than blood for epidemiological studies of HIV prevalence, especially among injecting drug users, has several practical advantages. In a cross-sectional, behavioural and prevalence study among drug users in Glasgow during 1990, salivary samples were therefore obtained by the use of salivettes. Such samples were requested for anonymous anti-HIV testing from 498 persons in locations varying from residential rehabilitation centres to the open streets. Of this number, 35 refused to give a sample, resulting in a compliance rate of 93%. Of the 463 salivettes received by the laboratory, eight were found to be dry. Of the remaining 455 specimens, eight were found to be positive for HIV-1 antibody by means of an IgG antibody capture ELISA, so giving a prevalence rate of 1.8%. The results of testing saliva and blood spot samples collected at the same time on filter paper from 98 persons for HIV-1 antibody were 100% concordant. The study confirms the experience of others that specimens of saliva are easy to collect under variable conditions by non-medical staff and demonstrates that the salivette can provide an HIV antibody test result the same as that obtained from a blood spot. The prevalence of HIV antibody determined in this study is similar to that of other studies taking place in the city during the same period of time.

HIV prevalence and HIV risk behaviour among injecting drug users in London and Glasgow.

This paper reports on the British findings from a cross-national study of HIV prevalence and HIV risk behaviour among 1,037 injecting drug users (IDUs) recruited from a variety of treatment- and community-based settings during 1990. Confirmed HIV saliva test results show 12.8% (63) of London respondents and 1.8% (8) of Glasgow respondents to be HIV antibody positive. Among London respondents, a higher rate of prevalence was found in those with no experience of drug treatment. A greater proportion of Glasgow respondents (68%) than London respondents (47%) reported sharing used injecting equipment in the 6 months prior to interview. The majority (88% in both cities) attempted cleaning borrowed equipment, although less than a third (31% in London and 30% in Glasgow) usually used bleach. The majority of respondents (71% in London and 82% in Glasgow) were sexually active with partners of the opposite sex in the last 6 months, and respondents had a mean number of 2.4 non-commercial sexual partners in London and 2.1 in Glasgow. Levels of reported condom use were comparable with reports in the heterosexual population as a whole, with 70% of London respondents and 75% of Glasgow respondents never using condoms with primary partners, and 34% of London and 52% of Glasgow respondents never using condoms with casual partners. Half (48%) of London respondents and 42% of Glasgow respondents reported sexual intercourse with non-injecting private sexual partners, while 14% of female respondents in London and 22% in Glasgow had engaged in prostitution. Levels of risk-taking in each of the two cities indicate the potential for further transmission of HIV among drug injectors, and their sexual and sharing partners.

The inappropriateness of psycho-social models of risk behaviour for understanding HIV-related risk practices among Glasgow male prostitutes.

Much the most common models of HIV-related risk behaviour are those psychosocial models derived from studies of health behaviour and tested on large interview samples of American gay men. These models were not appropriate for understanding risk behaviour among 32 Glasgow male prostitutes. Whereas psycho-social models conceive of risk behaviour as volitional and individualistic, ethnographic data indicate that the male prostitutes' risk practices were constrained and emergent from the immediate circumstances of the sexual encounter. Unsafe sex was associated with client control. Safer sex was associated with countervailing prostitute strategies of influence. These data confirm the utility of self-empowerment approaches to health education.

Facing up to acne.

Acne is generally considered to be a trivial condition, confined to adolescents, who are expected to 'grow out' of it by the time they become part of the working population. Dr Andrew Finlay's experience suggests otherwise and argues that acne can affect older sufferers and disable employees who are not referred for appropriate treatment.

A new method of estimating prevalence of injecting drug use in an urban population: results from a Scottish city.

Using modelling techniques derived from behavioural ecology, unnamed identifier data from a variety of partial samples of injecting drug users [IUDs] were used to estimate the prevalence of this population in Glasgow during 1989. The model yielded an estimate of 9424 [95% confidence interval +/- 2460] which represents a prevalence rate of 15 per 1000 population aged 15-55. The estimated male:female ratio was 2.64:1 and the modal IDU aged 20-24. These figures should facilitate assessment of the service requirements of this group and provide a basis from which the number of IDUs infected with HIV and the number likely to progress to AIDS can be determined. As the methodology required to facilitate reliable prevalence estimates utilizes relatively easy to obtain information it could be repeated in other urban centres where drug injecting is known to occur.
