Colposuspension with propylene mesh. A new technique for correction of urinary stress incontinence

This paper describes a survey undertaken to assess the caseload of HIV infected patients who received medical care from statutory service providers in England and Wales in 1996 in order to inform health authorities about the size and composition of their resident population of such patients. A total of 13,670 HIV infected patients were identified as living in England and Wales, 70% of whom lived in the Thames NHS executive regions. Over half the total caseload received care within their health authority of residence. Regional care centres attracted patients from wider areas, however, particularly in the North West and Thames regions. This survey of prevalent diagnosed HIV infections, one of a series conducted annually, provides public health specialists with information relevant to their localities without compromising patient confidentiality. Along with other data from the surveillance of AIDS cases and HIV infections it contributes to the assessment and projection of demands on health and social services and provides evidence on which to develop and direct national and local health campaigns.     

AIDS and severe HIV disease: combined predictions for the United Kingdom to 1999

The number of HIV infections prevalent in the United Kingdom (UK) at the end of 1994 have been estimated. Estimates of the future annual incidence and prevalence of AIDS and severe HIV disease have been calculated for the UK by combining recently published projections for Scotland with projections produced for England and Wales adjusted to account for Northern Ireland. The number of HIV infections prevalent in the UK at the end of 1994 was estimated to be about 23,000, 36% of them undiagnosed. It was estimated that 52% of prevalent infections were in homo/bisexual men, and 32% were in people exposed through heterosexual intercourse. Between 2100 and 2190 new cases of AIDS are expected to be reported in the UK each year from 1995 to 1999. It is predicted that a 30% rise in the number of cases exposed through heterosexual intercourse and a 17% rise in cases who inject drugs will be balanced by a 7% fall in cases among homo/bisexual men. Prevalent AIDS cases in the UK are expected to rise by 15%, from 3740 at the end of 1995 to 4290 at the end of 1999. The number of people expected to be living with severe HIV disease, including AIDS, will also rise by about 15%, from 7545 at the end of 1995 to 8650 at the end of 1999.     

Sexually transmitted diseases among teenagers in England and Wales

A profile of sexually transmitted diseases (STDs) and HIV infections among teenagers in England and Wales was obtained from reports of newly diagnosed STDs among teenagers attending genitourinary medicine (GUM) clinics in 1995, laboratory reports of newly diagnosed HIV infections between 1985 when reporting began and the end of 1995, and the prevalence of HIV (unlinked anonymous programme) among teenagers attending genitourinary medicine clinics and antenatal clinics in 1994 and 1995. STD reports were analysed by sex, age group, and place of residence of patients--whether in the NHS Thames regions or elsewhere in England and Wales. High rates of STDs were reported in teenagers, particularly in girls. The incidences of gonorrhoea, chlamydia infection, and first attack genital wart infections were higher in teenage girls than in any other age group. Boys under 16 years of age had substantially higher rates of infection with all STDs in the Thames regions than elsewhere. Rates of gonorrhoea in teenagers of both sexes in the Thames regions were more than twice those in the rest of the country. Infection rates for genital herpes, and chlamydia in girls, were also higher in the Thames regions, although the geographical differences were less marked. The seroprevalence of HIV among heterosexual teenagers was very low. In contrast, 226 HIV infections among teenage boys had probably been acquired through sexual intercourse with other males. Unlinked anonymous testing revealed HIV antibody in 7.5% of routinely collected serology specimens taken from teenage homosexual or bisexual males attending GUM clinics in London. The high rates of STDs among teenage girls and all teenagers in the Thames regions make these groups a high priority for sexual health promotion, with special consideration given to homo/bisexual male teenagers. Detailed surveillance of risk factors for STDs, and further studies of teenage sexual behaviour will help to effectively target resources to improve the sexual health of teenagers in England and Wales.     

Influenza surveillance in England and Wales: October 1995 to June 1996

This report summarises information collected for the surveillance of influenza virus infection in England and Wales from October 1995 to June 1996 (weeks 40/95 to 25/96). Total respiratory disease' activity, as reported by the Birmingham Research Unit of the Royal College of General Practitioners, rose to peaks in weeks 48/95, 51/95, and 01/96. The first peak coincided with a peak in "influenza and flu-like illness'. The subsequent peaks were accounted for by an increase in reports of acute bronchitis, including bronchiolitis, and may have been associated with the annual rise in infections with respiratory syncytial virus. Influenza A virus was responsible for most infections, with moderate activity occurring in the early part of the winter, peaking in December (week 48/95). Influenza A subtype H3N2 predominated until week 07/96, after which subtype H1N1 accounted for most infections. Influenza activity was first seen in central and northern England, followed by the south of England, Wales, and Scotland. Circulating influenza viruses were antigenically similar to the components of the 1995/96 vaccine. International surveillance during 1995/96 has led to a different H3N2 component being included in the influenza vaccine recommended for 1996/97.     

Health status of and access to health services by residents of urban encampments in Los Angeles

This paper reports findings from a survey of 134 homeless people living in 42 urban encampments in central Los Angeles. These data, of concern to public health officials, include the physical conditions in the camps, the health status of residents, their use of drugs and alcohol, and their access to and use of health care services such as substance abuse treatment. Many encampment residents report poor health status; over 30 percent report chronic illnesses, and 40 percent report a substance abuse problem. Although outreach efforts have had success in bringing HIV and tuberculosis screening services to encampments, residents report significant barriers to using primary health care and drug and alcohol treatment services. Public hospitals and clinics remain the major source of primary medical care for homeless people living in encampments. Outreach and case management continue to be critical components of improved access to health care for homeless people.     

Combining HIV and AIDS surveillance: an experience from an Italian region

BACKGROUND: Surveillance systems based on the reporting of AIDS cases do not provide a completely up to date picture of the trend of the HIV epidemic, stressing the need for systems based on the diagnosis of HIV infection. However, implementation of these systems has been hindered by low feasibility, poor access to HIV testing, and problems related to confidentiality. The advantages and disadvantages of the two systems and of combined use were explored by comparing and integrating information from AIDS and HIV testing registries in a region of Northern Italy. METHODS: Linkage of AIDS and HIV testing registries allowed the annual number of incident and prevalent infections to be calculated. For linked cases, concordance of exposure category was determined. RESULTS: Up to the end of 1995, 2186 AIDS cases and 5306 HIV-positive individuals were diagnosed. Linkage identified 1212 individuals reported to both registries. From 1990 to 1995, annual AIDS incidence steadily increased, while incidence of new HIV diagnoses decreased. The AIDS-to-AIDS-free ratio among those infected decreased from 1:5.6 in 1989 to 1:4.2 in 1995. The proportion of women and noninjecting drug users was higher among AIDS-free cases than among AIDS cases. The concordance of the exposure category was high (K = 0.70; 95% CI: 0.67-0.74), but it varied by exposure category; the highest concordance was for injecting drug users. CONCLUSIONS: Integrated use of the information provided by these surveillance systems allowed us to better understand and foresee the AIDS epidemic dynamics. The data also suggested that the reliability of information on exposure category may vary among categories.     

The provision of renal replacement therapy for adults in England and Wales: recent trends and future directions

We assessed the level of provision of renal replacement therapy for adults in England and Wales. All autonomous main renal units in England (n = 52) and Wales (n = 5) were surveyed in 1996. Data for England were compared to the 1993 National Renal Review. The acceptance rate in England 1995 was 82 (80-85) per million population (p.m.p.) compared with 67 (65-70) p.m.p. in 1991-2. The rate in 1995 in Wales was 109 (98-122) p.m.p. The prevalence rate in England was 476 p.m.p. at end-1995 compared to 393 p.m.p. in 1993, in Wales it was 487 p.m.p. The number of main renal units in England did not rise between 1993 and 1995; capacity was increased by use of more treatment shifts and temporary haemodialysis stations, and by opening more satellite units. The main growth was in hospital haemodialysis. There was an uneven geographical distribution of services. Patients accepted were older with more comorbidity. The use of better-quality processes of dialysis increased. The steady-state position for RRT will not be reached for over a decade. Health authorities will face continued pressure to fund increases in quantity and quality improvements. A stronger evidence base of the effectiveness of therapies, and a national registry to monitor the equity and cost-effectiveness of services are needed.     

Cytomegalovirus infection in England and Wales: 1992 and 1993

Cytomegalovirus causes illness through primary infection but also remains latent within the host and may be reactivated, especially if immunity is impaired. We have examined reports of cytomegalovirus infection from laboratories in England and Wales received by the PHLS Communicable Disease Surveillance Centre in 1992 and 1993. A total of 2938 reports were received, and 103 people had recurrent infections within the study period. The age distribution had peaks in infants (< 1 year of age) and in people aged 25 to 34 years. In almost a half of the patients (1371; 49%) factors were reported that indicated impaired immunity. Eighty-three of the 103 with recurrent infection (81%) were also reported to have impaired immunity. Children under 5 years accounted for 18% (543/2938) of reports. There were 930 reports of infections in people over 5 years of age who were not reported as immunocompromised. The data presented confirm that cytomegalovirus causes substantial morbidity in young children and people with impaired immunity. Cytomegalovirus infection causes considerable morbidity, especially hepatic, in patients whose immunity is thought to be normal.     

Patterns of mortality among Bangladeshis in England and Wales

OBJECTIVES: To investigate the patterns of mortality among Bangladeshis living in England and Wales. METHODS: An analysis of national mortality data, classified by country of birth, for the latest period (1988-1992), using the method of indirect standardization for deriving standardized mortality ratios (SMRs) with the age- and sex-specific rates for England and Wales as the standard (= 100). The SMRs were derived for Bangladeshi-born men and women aged 20-69 years for major disease entities. RESULTS: The mortality among Bangladeshi men was significantly higher (SMR 118 and 95% CI 111-126) than the levels prevalent in England and Wales. In contrast, the mortality among Bangladeshi women was significantly lower (SMR 71 and 95% CI 61-82). The cancer mortality overall was lower than expected in both sexes, with the exception of cancer of the liver and gall bladder. The mortality from breast cancer (SMR 16 and 95% CI 6-34) and cervical cancer (SMR 51 and 95% CI 14-131) was lower than expected. Bangladeshi men experienced high mortality from diabetes (SMR 685 and 95% CI 529-874), coronary heart disease (SMR 148 and 95% CI 134-163) and cerebrovascular disease (SMR 267 and 95% CI 222-319); they also experienced excess deaths from cirrhosis of the liver (SMR 254 and 95% CI 175-357). CONCLUSIONS: The findings establish significant variations in the recent health experiences of Bangladeshi men living in England and Wales, posing a major challenge for purchasers of care. If the Health of the Nation strategy is to ensure that equity in health and health care is to apply to all those living in this country, the Bangladeshi population needs special targeting.     

Uptake of interventions to reduce mother-to-child transmission of HIV in the United Kingdom and Ireland

OBJECTIVES: To describe the uptake of interventions to reduce mother-to-child transmission of HIV infection. DESIGN: Voluntary confidential reporting of HIV infection in pregnancy and childhood; telephone interview with key professionals in all London maternity units. SUBJECTS AND SETTING: HIV-infected pregnant women and children in the United Kingdom and Ireland. MAIN OUTCOME MEASURES: Trends in breastfeeding, use of zidovudine, mode of delivery and terminations of pregnancy. RESULTS: Between 1990 and 1995, 14 (4%) out of 314 women diagnosed with HIV infection before delivery breastfed compared with 109 (77%) out of 142 diagnosed after delivery. Since 1994, zidovudine use has increased in each 6-month period (14, 39, 67, and 75%; chi 2 = 17.5, P < 0.001), although in 1995 it was the policy of only 48% of London maternity units to offer zidovudine to HIV-infected women. During 1995, 44% of HIV-infected women were delivered by elective Cesarean section. Since 1990, 20% of women first diagnosed in pregnancy were reported to have their pregnancy terminated. CONCLUSIONS: Although detection of previously undiagnosed HIV infection in pregnancy remains low in the United Kingdom, and particularly in London, HIV-infected pregnant women who are aware of their status are increasingly active in taking up interventions to reduce transmission to their infants. If all HIV-infected women attending for antenatal care in London consented to testing and took up interventions and termination of pregnancy at the rates observed in this study, the number of vertically infected babies born in London each year could be reduced from an estimated 41 to 13.     

Meningococcal disease in England and Wales: 1995

The number of laboratory confirmed cases of meningococcal infection in England and Wales rose in 1995 for the first time since 1990. Culture confirmed cases rose to 1459, an increase of 29% over the 1994 total, due largely to increased disease activity in the last quarter of 1995. Cases diagnosed by non-culture methods totalled 431, giving a total of 1890 laboratory confirmed cases. Notifications reported to the Office of Population Censuses and Surveys also increased to a similar extent. Northern regions generally had higher rates of disease activity and greater increases in rates. Meningococcal disease caused by serogroup C strains accounted for the main increase in culture confirmed cases and made up 32% of the total in 1995. Disease caused by C2a strains showed a particularly large increase. A change in the age distribution was noted with a greater proportion of patients in older age groups. Among group B isolates, B4 P1.4 strains continued to be identified most commonly.     

Fatal and non-fatal childhood injuries in Metropolitan Toronto, 1986-1991

OBJECTIVE: To estimate the prevalence of human immunodeficiency virus (HIV) infection among health care workers who donate blood. DESIGN: Point prevalence survey of blood donors. SETTING: 20 U.S. blood centers that participate in an ongoing interview study of HIV-seropositive blood donors. MEASUREMENTS: Prevalence rates for HIV in persons who reported being health care workers were measured directly for 6 of the 20 blood centers. For the other 14 centers, we derived the numerator from the interview study in the same manner used for the 6 centers; we estimated the denominator using blood collection logs at those centers and extrapolations from the survey completed at the 6 blood centers. RESULTS: Between March 1990 and August 1991, 8519 health care workers donated blood at 6 hospitals and other medical facilities. Three persons were HIV seropositive: Two reported being health care workers and having nonoccupational risk factors for HIV infection; the occupation and other possible risk factors of the third seropositive donor could not be determined. Therefore, the highest overall prevalence of HIV infection among health care worker donors at these 6 centers was 0.04% (3 of 8519; upper limit of 95% CI, 0.1%). We estimated that during the same period, approximately 36,329 health care workers were tested for HIV at all 20 centers. Twenty-seven persons infected with HIV who donated at hospitals were identified; 7 did not return for interviews, so their health care occupations could not be verified. Thus, the highest estimated overall prevalence of HIV infection among health care worker donors at the 20 centers was 0.07% (27 of 36,329; upper limit of CI, 0.1%). Of the 20 known health care worker donors, 11 reported nonoccupational risks for HIV infection; 3 of the remaining 9 health care workers described occupational blood exposures that could have resulted in transmission of HIV. CONCLUSIONS: Blood donors can serve as a sentinel cohort when evaluating the risk for occupationally acquired HIV infection. These findings suggest that among the many health care worker donors in this study, HIV infection attributable to occupational exposure was uncommon.     

A survey of psychologists' education, knowledge, and experience treating clients with HIV/AIDS.

Practicing psychologists are providing services to persons with HIV infection and those at-risk for AIDS. However, most practitioners have not received formal training about HIV/AIDS. In this study, the majority of psychologists surveyed had treated persons at-risk for the virus but had not received HIV/AIDS information in formal educational programs. Most respondents obtained knowledge through popular media. There is a growing body of specialized knowledge about HIV/AIDS for mental health professionals. In addition to better serving HIV-infected clients, psychologists with current multidisciplinary HIV/AIDS knowledge will be valuable members of health care teams.

Financing HIV service provision in England: estimated impact of the cost of antiretroviral combination therapy

The objective of this study was to provide population-based estimates on the cost of HIV service provision in England and the use of dual or triple antiretroviral combination therapy. Contemporary cost estimates of treating HIV-infected individuals by clinical stage of HIV infection (indexed to 1995/96 prices) were linked to the number of diagnosed HIV-infected individuals using statutory medical services in England during 1996. Two cost measures were used: the first one was based on average hospital prices derived from a number of English HIV units. These results were compared with those estimated using standard unit costs obtained through specific costing studies performed at a national HIV referral centre. Overall annual expenditure on HIV service provision was estimated for different treatment scenarios as was expenditure by clinical stage of HIV infection. Using hospital prices, in 1996 the total annual cost estimate for HIV service provision amounted to pound sterling 131 m (range pound sterling 83 m to pound sterling 233 m), or pound sterling 150 m (95% CI pound sterling 126 m to pound sterling 173 m) using standard costs, if all patients with HIV disease were treated with AZT monotherapy. For all eligible patients to be treated with dual therapy, cost estimates amounted to pound sterling 161 m (range pound sterling 126 m to pound sterling 173 m) per year using hospital prices or pound sterling 180 m (95% CI pound sterling 156 m to pound sterling 203 m) when using standard cost estimates, while for triple therapy annual estimated expenditure amounted to pound sterling 204 m per year (range pound sterling 157 m to pound sterling 306 m) when using hospital prices or pound sterling 223 m (95% CI pound sterling 199 m to pound sterling 246 m) using standard costs. Increasingly costs will be more evenly distributed across the 3 stages of HIV infection, with a greater proportion of costs generated by HIV-infected individuals before the onset of AIDS. Using non-standardized hospital prices may systematically underestimate the real cost of service provision. Monitoring prospectively the use, cost and outcome of HIV service provision in a standardized format will provide information on the actual cost impact over the next 2-3 years of combination therapy compared with the scenario-based estimates produced in this paper.     

Utilisation of genitourinary medicine services by general practitioners: effect of geographic location, fundholding status, and potential effect of total fundholding

OBJECTIVES: To determine the current utilisation of genitourinary medicine (GUM) services by general practitioners (GPs) and any changes likely to occur with moves towards a primary care led NHS. METHODS: A questionnaire survey of practising GPs appearing in the Medical Directory in England and Wales to determine the effect of geographical location, fundholding status, and potential effect of total fundholding on referrals to GUM clinics. RESULTS: Referral patterns for STDs varied according to the genital infection concerned, being highest for gonorrhoea and lowest for Trichomonas vaginalis infection. Referral patterns were little affected by geographic location of the practice or fundholding status. The reported intention on becoming total fundholding was a modest shift towards more STDs being treated in the community which varied according to the genital infection concerned. CONCLUSIONS: Although some GPs elect to always treat some STDs in the community most refer patients to GUM clinics. There appears to be little enthusiasm among GPs, should they become total fundholders, to extend their range of services to include STD provision.     

Excess mortality in England and Wales, and in Greater London, during the 1995 heatwave

STUDY OBJECTIVE: To assess the impact on mortality of the heatwave in England and Wales during July and August 1995 and to describe any difference in mortality impact between the Greater London urban population and the national population. DESIGN: Analysis of variation in daily mortality in England and Wales and in Greater London during a five day heatwave in July and August 1995, by age, sex, and cause. SETTING: England and Wales, and Greater London. MAIN RESULTS: An estimated 619 extra deaths (8.9% increase, approximate 95% confidence interval 6.4, 11.3%) were observed during this heatwave in England and Wales, relative to the expected number of deaths based on the 31-day moving average for that period. Excess deaths were apparent in all age groups, most noticeably in women and for deaths from respiratory and cerebrovascular disease. Using published daily mortality risk coefficients for air pollutants in London, it was estimated that up to 62% of the excess mortality in England and Wales during the heatwave may be attributable to concurrent increases in air pollution. In Greater London itself, where daytime temperatures were higher (and with lesser falls at night), mortality increased by 16.1% during the heatwave. Using the same risk coefficients to estimate the excess mortality apparently attributable to air pollution, more than 60% of the total excess in London was apparently attributable to the effects of heat. CONCLUSION: Analysis of this episode shows that exceptionally high temperatures in England and Wales, though rare, do cause increases in daily mortality.     

Tuberculosis in England and Wales in 1993: results of a national survey. Public Health Laboratory Service/British Thoracic Society/Department of Health Collaborative Group

BACKGROUND: A national survey of tuberculosis notifications in England and Wales was carried out in 1993 to determine the notification rate of tuberculosis and the trends in the occurrence of disease by ethnic group in comparison with the findings of similar surveys in 1978/79, 1983, and 1988. The prevalence of HIV infection in adults notified with tuberculosis in the survey period was also estimated. METHODS: Clinical, bacteriological, and sociodemographic information was obtained on all newly notified cases of tuberculosis in England and Wales during the six months from 2 January to 2 July 1993. The prevalence of HIV infection in 16-54 year old patients with tuberculosis notified throughout 1993 was assessed using "unlinked anonymous" testing supplemented by matching of the register of patients with tuberculosis with that of patients with AIDS reported to the PHLS AIDS centre. Annual notification rates were calculated using population estimates from the 1993 Labour Force Survey. RESULTS: A total of 2706 newly notified patients was eligible for inclusion in the survey of whom 2458 were previously untreated the comparable figures for 1988 were 2408 and 2163. The number of patients of white ethnic origin decreased from 1142 (53%) in 1988 to 1088 (44%) in 1993 whereas those of patients of Indian, Pakistani, or Bangladeshi (Indian subcontinent (ISC)) ethnic origin increased from 843 (39%) in 1988 to 1014 (41%) and those of "other" (non-white, non-ISC) ethnic origins increased from 178 (8%) to 356 (14%). The largest increase was seen in the black African ethnic group from 37 in 1988 to 171 in 1993. Forty nine per cent of patients had been born abroad and the highest rates were seen in those who had recently arrived in this country. The overall annual notification rate for previously untreated tuberculosis in England and Wales increased between 1988 and 1993 from 8.4 to 9.2 per 100,000 population. The rate declined in the white, Indian, and black Caribbean ethnic groups and increased in all other groups. In the white group the rate of decline has slowed since the last survey: in several age groups the rates were higher in 1993 than 1988 but the numbers in these groups were small. Thirty six (4.1%) of the 882 previously untreated respiratory cases were resistant to isoniazid and three (0.3%) to isoniazid and rifampicin. Sixty two (2.3%) adults aged 16-54 years were estimated to be HIV-infected. Evidence of under-reporting of HIV positive tuberculosis patients was found. CONCLUSIONS: The number of cases and annual notification rate for previously untreated tuberculosis increased between 1988 and 1993. Although the decline in rates in the white population has continued, the rate of decline has slowed. The high rates in the ISC ethnic group population have continued to decline since 1988 whereas rates in the black African group have increased. An increased proportion of cases were found among people born abroad, particularly those recently arrived in this country. In previously untreated cases the level of drug resistance remains low and multi-drug resistance is rare. A small proportion of adults with tuberculosis were infected with HIV but there may be selective undernotification of tuberculosis in these patients.     

The role of the general practitioner in the community care of people with HIV infection and AIDS: a comparative study of high- and low-prevalence areas in England

BACKGROUND: Policy for the care of people suffering from HIV and AIDS has changed over the past decade. Schemes for shared primary and secondary care have been met with varying success, and patients may be reluctant to become involved. No systematic evaluation comparing the views of primary care providers and users in areas of varying HIV prevalence has been published. AIM: To examine the role of general practice in areas of England with low and high human immunodeficiency virus (HIV) prevalence and to compare barriers to general practice care in each area. METHOD: We used focus groups, semistructured questionnaires and interviews in north London (high HIV prevalence) and Nottingham (low HIV prevalence). RESULTS: Four focus groups took place in London. A total of 411 general practitioners (GPs) in London and 405 in Nottingham replied to postal questionnaires. Overall, 121 primary care staff in 40 London practices and 26 staff in five Nottingham practices were interviewed. In all, 54 people infected with HIV were interviewed in London and 20 in Nottingham. Providers and users regarded the 24-hour availability and the familiar environment of general practice as its key assets. Lack of expertise and time were its disadvantages. Providers were concerned about inadequate communication with specialist services. Although providers were concerned about confidentiality, whether they had liberal and sympathetic attitudes was more important in deciding whether people with HIV used the service. In the low-prevalence area, general practice involvement was the result of individual initiatives, and practices were not integrated into specialist care. In the high-prevalence area, HIV care was more usual in general practice, but there was also little integration with HIV services. CONCLUSIONS: In high-prevalence districts, a strategy to make HIV care routine for all GPs may be appropriate. In low-prevalence areas, a network of selected, strategically located, relatively high-involvement practices may be more effective in meeting the primary care needs of people with HIV infection and acquired immunodeficiency syndrome (AIDS).     

Consumer information, patient satisfaction surveys, and public reports

This article describes information useful for consumers and purchasers in making choices about health care services. Two types of information are described, patient satisfaction surveys and public reports about the price and outcomes of health care services such as those published by the Pennsylvania Health Care Cost Containment Council. Patient satisfaction surveys can be used to provide valuable information about health care. The goal of patient satisfaction reporting is to incorporate the patient's perspective to improve care. Public reports about the price and outcome of hospital and physician services not only facilitate consumer and purchaser choice, they also encourage continuous quality improvement by providers.
