National survey of tuberculosis notifications in England and Wales 1978--9. Report from the Medical Research Council Tuberculosis and Chest Diseases Unit.

A survey of all tuberculosis notifications in England and Wales for a six-month period showed that 70% of 3732 newly notified, previously untreated patients had respiratory disease only, 23% had non-respiratory disease only, and 7% had both. Fifty-seven per cent of patients were of white and 35% were of Indian subcontinent (Indian, Pakistani, or Bangladeshi) ethnic origin, the latter group contributing over half the cases of non-respiratory disease. The estimated overall annual notification rate per 100 000 population for 1978--9 was 16.4 for England and 13.5 for Wales. The rates differed considerably between the different ethnic groups in England, the highest rates occurring in the Indian and in the Pakistani and Bangladeshi groups and the lowest in the white group; the differences in the non-respiratory rates were the more striking. Nearly a quarter of patients with respiratory disease had large pulmonary lesions, the proportion being higher for the white group than for the Indian subcontinent group. Over half the patients had positive cultures for tubercle bacilli and over a third had positive smears; both proportions were higher for the white group. This survey has identified many of the problems which tuberculosis presents in England and Wales today. These include the substantial number of patients with sputum-positive disease, the considerable variation in the rates in the different ethnic groups, and the not uncommon occurrence of childhood tuberculosis.     

National survey of notifications of tuberculosis in England and Wales in 1983. Medical Research Council Tuberculosis and Chest Diseases Unit.

In a survey of all notifications of tuberculosis in England and Wales for the first six months of 1983 56% of the 3002 newly notified patients who had not been treated before were of white and 37% were of Indian subcontinent (Indian, Pakistani, or Bangladeshi) ethnic origin, findings similar to those of a survey in 1978-9. In the four and a quarter years between the surveys the number of patients notified had declined by 26%, the decline being 28% among those of white and 23% among those of Indian subcontinent ethnic origin. The white patients were on average older than the patients of Indian subcontinent ethnic origin, and a higher proportion of them had respiratory disease (82% compared with 66%). The pulmonary lesions were on average larger and more often bacteriologically positive in the white patients. There were considerable differences between the ethnic groups in the estimated yearly rates of notifications per 100 000 population in England in 1983. The highest rates occurred in the Indian (178) and the Pakistani and Bangladeshi (169) populations and were roughly 25 times the rate in the white population (6 X 9). In the Indian subcontinent ethnic groups the highest rates occurred among those who had arrived in the United Kingdom within the previous five years.     

Role of the private sector in elective surgery in England and Wales, 1986.

From a sample of 19,000 treatment episodes at 183 of the 193 independent hospitals with operating facilities in England and Wales that were open in 1986 it is estimated that 287,000 residents of England and Wales had elective surgery as inpatients in 1986 (an increase of 77% since 1981) and 72,000 as day cases. From 1985 Hospital In-Patient Enquiry data it was estimated that a further 36,000 similar elective inpatient treatments were undertaken in NHS pay beds (a decrease of 38%) and 21,000 as day cases. Overall, an estimated 16.7% of all residents of England and Wales who had non-abortion elective surgery as inpatients were treated in the private sector, as were 10.5% of all day cases. An estimated 28% of all total hip joint replacements were done privately, and in both the North West and South West Thames regions the proportion of inpatients treated privately for elective surgery was 31%. It is concluded that mainly for reasons of available manpower private sector activity may not be able to grow much more without arresting or reversing the growth of the NHS, in which case some method of calculating NHS resource allocation which takes account of the local strength of the private sector will be needed.     

BCG immunisation in England and Wales: a survey of policy and practice in schoolchildren and neonates.

OBJECTIVE--To determine the policy and practice of district health authorities in England and Wales for BCG immunisation in schoolchildren and neonates. DESIGN--Self completion postal questionnaire survey. PARTICIPANTS--District immunisation coordinators. SETTING--199 district health authorities in England and Wales. RESULTS--Questionnaires were received from 186 districts, a response rate of 94%. Considerable uniformity was observed in many aspects of BCG immunisation policy and practice but some important variations were found. 15 districts no longer carry out a routine schools programme. 148 districts offer BCG to selected groups of neonates and five to all neonates, but 31 districts do not offer BCG to this age group. The recommended action in response to different levels of tuberculin sensitivity in schoolchildren and neonates varied among districts. CONCLUSIONS--Despite the recommendations of the Joint Committee on Vaccination and Immunisation some districts do not offer BCG immunisation to neonates at high risk of tuberculosis and there are important variations in other aspects of BCG policy.     

Patient characteristics and clinical caseload of short stay independent hospitals in England and Wales, 1992-3.

OBJECTIVE--To describe and quantify the patients and clinical activities of independent short stay hospitals. DESIGN--Retrospective survey of hospital records for sampled periods of one financial year and comparison with data from 1981 to 1986. SETTING--217 independent hospitals in England and Wales, 1992-3. MAIN OUTCOME MEASURES--Distributions of sex, age groups, and areas of residence of patients, clinical procedures, financial provision. RESULTS--Data were obtained from 201 (93%) hospitals. An estimated 429,172 inpatients (7% more than 1986) and 249,531 day cases (an increase of 154%) from 1986 were treated in the year. The number of overseas patients was half that in 1986. Clinical case mix remained similar to 1986. Abortion remained the commonest procedure (13% v 19% in 1986). Lens operations, heart operations, endoscopies, and non-surgical cases showed the largest increases from 1986. Proportionately more overseas patients had abortions (30% v 12% for England and Wales residents) and they received 41% of coronary artery bypass grafting. Three quarters of the patients were aged 15-64. The proportion of patients aged over 65 had changed little (19% v 17% in 1986). Estimated average bed occupancy was only 48%. Only one in 20 patients was treated under NHS contract; 90% of episodes were funded through private health insurance. CONCLUSIONS--The demand for treatment in private hospitals continues to increase despite additional investment in the NHS, but the overseas market is falling. Overall, the range of clinical activity has changed little.     

Are healthcare workers in England and Wales at increased risk of tuberculosis?

OBJECTIVE: To determine whether healthcare workers in England and Wales are at increased risk of tuberculosis and to examine the frequency of drug resistance in this population. DESIGN: Comparison of notification rates by occupation obtained from national tuberculosis notification surveys in 1988 and 1993, with denominators from the 1991 census. SUBJECTS: People with notified tuberculosis in professional and associate professional occupations from the two surveys. MAIN OUTCOME MEASURES: Rates of notified tuberculosis in health professionals (mainly doctors) and health associate professionals (mainly nurses) compared with rates in other professional and associate professional occupations, adjusted for ethnic group, sex, and age. RESULTS: 119 cases of tuberculosis were identified in healthcare workers, including 61 nurses and 42 doctors. The crude notification rate in healthcare workers was 11.8 per 100,000 per year (95% confidence interval 9.8 to 14.1) compared with 3.3 per 100,000 per year (2.9 to 3.6) in other professional and associate professional occupations; rate ratios were higher (range 1.7 to 3.2) in all ethnic groups. The relative risk adjusted for ethnic group, sex, and age was 2.4 (95% confidence interval 2.0 to 3.0), slightly higher for health professionals (2.7 (1.9 to 3.8)) than for associate professionals (2.0 (1.5 to 2.6)). No multiple drug resistant strains of tuberculosis were identified in healthcare workers. CONCLUSIONS: Better detection and notification of cases of tuberculosis in healthcare workers may account for some of the apparent increased risk, but these findings imply that tuberculosis remains a hazard for healthcare workers and highlight the importance of ensuring that occupational health monitoring and protection workers are not neglected.     

Ethnic differences in general practitioner consultations.

OBJECTIVE--To examine the levels of general practitioner consultations among the different ethnic groups resident in Britain. DESIGN--The study was based on the British general household surveys of 1983-5 and included 63,966 people aged 0-64. Odds ratios were derived for consultation by ethnic group by using logistic regression analysis adjusting for age and socioeconomic group. SETTING--The results relate to people living in private households in England, Scotland, and Wales. RESULTS--After adjustment for age and socioeconomic class, consultation among adults aged 16-64 was highest among people of Pakistani origin with odds ratios of 2.82 (95% confidence interval 1.86 to 4.28) for men and 1.85 (1.22 to 2.81) for women. Significantly higher consultations were also seen for men of West Indian and Indian origin (odds ratios 1.65 and 1.53 respectively). Ethnic differences were greatest at ages 45-64, when consultation rates in people of Pakistani, Indian, and West Indian origin were much higher in both sexes compared with white people. CONCLUSIONS--The ethnic composition of inner cities is likely to influence the workload and case mix of general practitioners working in these areas.     

Excess years of life lost to COVID-19 and other causes of death by sex,neighbourhood deprivation,and region in England and Wales during 2020: A registry-based study

BackgroundDeaths in the first year of the Coronavirus Disease 2019 (COVID-19) pandemic in England and Wales were unevenly distributed socioeconomically and geographically. However, the full scale of inequalities may have been underestimated to date, as most measures of excess mortality do not adequately account for varying age profiles of deaths between social groups. We measured years of life lost (YLL) attributable to the pandemic, directly or indirectly, comparing mortality across geographic and socioeconomic groups.Methods and findingsWe used national mortality registers in England and Wales, from 27 December 2014 until 25 December 2020, covering 3,265,937 deaths. YLLs (main outcome) were calculated using 2019 single year sex-specific life tables for England and Wales. Interrupted time-series analyses, with panel time-series models, were used to estimate expected YLL by sex, geographical region, and deprivation quintile between 7 March 2020 and 25 December 2020 by cause: direct deaths (COVID-19 and other respiratory diseases), cardiovascular disease and diabetes, cancer, and other indirect deaths (all other causes). Excess YLL during the pandemic period were calculated by subtracting observed from expected values. Additional analyses focused on excess deaths for region and deprivation strata, by age-group. Between 7 March 2020 and 25 December 2020, there were an estimated 763,550 (95% CI: 696,826 to 830,273) excess YLL in England and Wales, equivalent to a 15% (95% CI: 14 to 16) increase in YLL compared to the equivalent time period in 2019. There was a strong deprivation gradient in all-cause excess YLL, with rates per 100,000 population ranging from 916 (95% CI: 820 to 1,012) for the least deprived quintile to 1,645 (95% CI: 1,472 to 1,819) for the most deprived. The differences in excess YLL between deprivation quintiles were greatest in younger age groups; for all-cause deaths, a mean of 9.1 years per death (95% CI: 8.2 to 10.0) were lost in the least deprived quintile, compared to 10.8 (95% CI: 10.0 to 11.6) in the most deprived; for COVID-19 and other respiratory deaths, a mean of 8.9 years per death (95% CI: 8.7 to 9.1) were lost in the least deprived quintile, compared to 11.2 (95% CI: 11.0 to 11.5) in the most deprived. For all-cause mortality, estimated deaths in the most deprived compared to the most affluent areas were much higher in younger age groups, but similar for those aged 85 or over. There was marked variability in both all-cause and direct excess YLL by region, with the highest rates in the North West. Limitations include the quasi-experimental nature of the research design and the requirement for accurate and timely recording.ConclusionsIn this study, we observed strong socioeconomic and geographical health inequalities in YLL, during the first calendar year of the COVID-19 pandemic. These were in line with long-standing existing inequalities in England and Wales, with the most deprived areas reporting the largest numbers in potential YLL.

In a registry-based study, Evangelos Kontopantelis and colleagues examine the excess years of life lost to COVID-19 and other causes of death by sex, neighbourhood deprivation and region in England & Wales during 2020.     

Wartime evacuation and mortality from childhood leukaemia in England and Wales in 1945-9.

OBJECTIVE--To discover whether the wartime government evacuation of children from London and other population centres to rural districts was associated with any increase in childhood leukaemia. DESIGN--Observational study of mortality from leukaemia among the childhood population of England and Wales in relation to the unique population movements during the second world war. The 476 rural districts of England and Wales were ranked according to the ratio of government evacuees (two thirds of them children) to local children in September 1941. The districts were divided into three categories, each with similar numbers of children in 1947 but with different ratios of evacuees to local children ("low," "intermediate," "high"). Mortality from childhood leukaemia was examined in these three rural categories in 1945-9. Urban areas were also examined according to their exposure to evacuees. SETTING--Local authority areas of England and Wales. SUBJECTS--Children aged under 15. RESULTS--47% excess of leukaemia at ages 0-14 years occurred in 1945-9 in the rural "high" category for evacuees relative to the "low" category, with a significant trend across the three categories. There were increases in both the 0-4 and 5-14 year age groups, but these were larger in the older age group. Rates 25% lower than average occurred in rural areas with few evacuees. CONCLUSION--These findings suggest that wartime evacuation increased the incidence of childhood leukaemia in rural areas and that other forms of population mixing may have contributed to the increases in past decades. Overall, they add to the appreciable evidence for an infective basis in childhood leukaemia.     

Tuberculosis among immigrants related to length of residence in England and Wales. Report from the British Thoracic and Tuberculosis Association.

Between 1965 and 1971 the notifications of tuberculosis among lifetime residents of the British Isles declined, but among those born in India, Pakistan, and new Commonwealth countries in Africa tuberculosis notifications increased appreciably. Furthermore, the long-held suspicion that among these immigrants the most recent arrivals in England and Wales have higher rates of tuberculosis than those who have lived here longer was confirmed.     

Child height and intergenerational transmission of health: Evidence from ethnic Indians in England

A large literature documents a widespread prevalence of small stature among Indian children as well as adults. We show that a height gap relative to a richer population such as whites in England also exists, although substantially reduced, among adult immigrants of Indian ethnicity in England. This is despite positive height selection into migration, demonstrated by ethnic Indian adults in England being on average 6–7 cm taller than in India. However, the difference between natives and ethnic Indians in England disappears among their younger sons and daughters, although it re-appears among adolescents. We estimate that, conditional on age, gender and parental height, ethnic Indian children of age 2–4 in England are 6–8% taller than in India. Such degree of catch up in one generation is remarkable, also because in England children of ethnic Indians have much smaller birthweight than whites, by about 0.4 kg on average.     

HIV infection in patients attending clinics for sexually transmitted diseases in England and Wales. Collaborative Study by Consultants in Genitourinary Medicine and the Public Health Laboratory Service.

A national study of the prevalence of HIV antibody designed to monitor sexual spread of HIV infection in England and Wales was made of homosexual and heterosexual patients attending sexually transmitted disease clinics in four districts in 1985, seven in 1986, and 14 in 1987. Patients were invited to participate and were counselled. Among homosexual men in two clinics in south east England, HIV antibody was found in 92 (12.9%) of 711 in 1985, 65 (15.2%) of 428 in 1986, and 81 (14.6%) of 556 in 1987: corresponding findings in the other regions were 16 (5.0%) of 321, 41 (6.3%) of 654, and 21 (3.1%) of 678. The prevalence of HIV antibody was higher in homosexual than bisexual men, in patients aged 25 years or more, or with one or more specified minor complaints. Among heterosexual patients in the south east in 1986, HIV antibody was found in seven (3.0%) of 230 men and three (1.3%) of 233 women and in 1987 in 10 (1.0%) of 962 men and seven (0.7%) of 949 women. In other areas corresponding findings in 1986 were two (0.2%) of 950 men and three (0.4%) of 752 women and in 1987 were three (0.06%) of 5312 men and one (0.02%) of 4778 women. All but one of the heterosexual patients with the antibody were intravenous drug abusers or had had sexual contacts in or were from an area abroad with a high prevalence of AIDS. Failure to identify a heterosexual patient with HIV antibody not in a risk group (other than that of being an attender at the clinic) or who did not have a sexual partner in a risk group suggests that their prevalence in the patient population of the clinics in the south east is less than one in 700 and in the other regions less than one in 3000. Refusals to participate increased during the study but comparisons of patients who agreed and refused in terms of age, the presence of symptoms suggesting AIDS, travel abroad, and number of sexual partners a month showed little evidence of selective bias.     

Increasing antituberculosis drug resistance in the United Kingdom: analysis of national surveillance data

Objective To identify recent trends in, and factors associated with, resistance to antituberculosis drugs in England, Wales, and Northern Ireland.Design Cohort of tuberculosis cases reported to the enhanced tuberculosis surveillance system matched to data on drug susceptibility and national strain typing data.Setting England, Wales, and Northern Ireland 1998-2005.Main outcome measures Unadjusted and adjusted odds ratios for drug resistance and associated factors. Proportion of multidrug resistant tuberculosis cases clustered.Results 28 620 culture confirmed cases were available for analysis. The proportion of cases resistant to isoniazid increased from 5% to 7%. Rifampicin resistance increased from 1.0% to 1.2% and multidrug resistance from 0.8% to 0.9%. Ethambutol and pyrazinamide resistance remained stable at around 0.4% and 0.6%, respectively. Regression analyses showed a significant increase in isoniazid resistance outside London (odds ratio 1.04, 95% confidence interval 1.01 to 1.07, a year, associated with changes in age (0.98, 0.98 to 0.99, a year), place of birth (1.49, 1.16 to 1.92), and ethnicity (P<0.05). In London, the rise (1.05, 1.02 to 1.08, a year) was related mainly to an ongoing outbreak. Increases in rifampicin resistance (1.06, 1.01 to 1.11, a year) and multidrug resistance (1.06, 1.00 to 1.12, a year) were small. A fifth of patients with multidrug resistant tuberculosis in 2004-5 had indistinguishable strain types, and one case was identified as extensively drug resistant.Conclusions The rise in isoniazid resistance reflects increasing numbers of patients from sub-Saharan Africa and the Indian subcontinent, who might have acquired resistance abroad, and inadequate control of transmission in London. The observed increases highlight the need for early case detection, rapid testing of susceptibility to drugs, and improved treatment completion.     

Social class differences in infant mortality in Sweden: comparison with England and Wales.

OBJECTIVES--To investigate social class differences in infant mortality in Sweden in the mid-1980s and to compare their magnitude with that of those found in England and Wales. DESIGN--Analysis of risk of infant death by social class in aggregated routine data for the mid-1980s, which included the linkage of Swedish births to the 1985 census. SETTING--Sweden and England and Wales. SUBJECTS--All live births in Sweden (1985-6) and England and Wales (1983-5) and corresponding infant deaths were analysed. The Swedish data were coded to the British registrar general''s social class schema. MAIN OUTCOME MEASURES--Risk of death in the neonatal and postneonatal period. RESULTS--Taking the non-manual classes as the reference group, in the neonatal period in Sweden the manual social classes had a relative risk for mortality of 1.20 (95% confidence interval 1.02 to 1.43) and those not classified into a social class a relative risk of 1.08 (0.88 to 1.33). In the postneonatal period the equivalent relative risks were 1.38 (1.08 to 1.77) for manual classes and 2.14 (1.65 to 2.79) for the residual; these are similar to those for England and Wales (1.43 (1.36 to 1.51) for manual classes, 2.62 (2.45 to 2.81) for the residual). CONCLUSIONS--The existence of an equitable health care system and a strong social welfare policy in Sweden has not eliminated inequalities in post-neonatal mortality. Furthermore, the very low risk of infant death in the Swedish non-manual group (4.8/1000 live births) represents a target towards which public health interventions should aim. If this rate prevailed in England and Wales, 63% of postneonatal deaths would be avoided.     

Analysis of the sociodemography of gonorrhoea in Leeds, 1989-93.

OBJECTIVE: To investigate the epidemiology of gonorrhoea in an urban area in the United Kingdom. DESIGN: Analysis of all cases of gonorrhoea with regard to age, sex, ethnic group, and socioeconomic group with 1991 census data as a denominator. SETTING: Leeds, a comparatively large urban area (population around 700,000) in the United Kingdom. SUBJECTS: All residents of Leeds with culture proved cases of gonorrhoea during 1989-95. MAIN OUTCOME MEASURE: Relative risk of gonorrhoea. RESULTS: Sex, age, race, and socioeconomic group and area of residence were all independently predictive of risk of infection. Young black men aged 20-29 were at highest risk, with incidences of 3-4% per year. Black subjects were 10 times more likely than white subjects to acquire infection, and subjects from the most deprived socioeconomic areas were more than four times more likely than those from the most affluent areas to acquire infection. CONCLUSIONS: Different ethnic and socioeconomic groups vary in their risk of infection with gonorrhoea within an urban area. Targeted interventions and screening to reduce the incidence of sexually transmitted disease are now priorities.     

Comparison of the activity of short stay independent hospitals in England and Wales, 1981 and 1986.

From a sample of 19,000 treatment episodes at 183 of the 193 independent hospitals with operating facilities in England and Wales that were open during 1986 it is estimated that 404,000 inpatients were treated in 1986 (an increase of 48% since 1981) and 99,000 day cases (an increase of 112%). It was found that the procedure most commonly performed was abortion, though this made up only 19% of the total caseload in 1986 compared with 30% in 1981, otherwise the case mix in 1986 was similar to that in 1981. Fewer patients came from overseas in 1986 than in 1981, but the distribution by age and sex remained the same, with three quarters of the patients aged between 15 and 65. The estimated bed occupancy in the independent hospitals in 1986 was less than 60% nationally and only 52% in the Thames regions. It is concluded that in these five years the nature of the independent hospital sector changed little, and in 1986 the activity still consisted largely of routine cold elective surgery for people of working age, and the regional differences in admission rates to independent hospitals were nearly as great as in 1981.     

Sudden infant death syndrome and postneonatal mortality in immigrants in England and Wales.

To examine ethnic differences in postneonatal mortality and the incidence of sudden infant death in England and Wales during 1982-5 records were analysed, the mother''s country of birth being used to determine ethnic group. Postneonatal mortality was highest in infants of mothers born in Pakistan (6.4/1000 live births) followed by infants of mothers born in the Caribbean (4.5) and the United Kingdom and Republic of Ireland (4.1). Crude rates were lower in infants of mothers born in India (3.9/1000), east and west Africa (3.0), and Bangladesh (2.8) than in infants of mothers born in the United Kingdom despite less favourable birth weights. Mortality ratios standardised separately for maternal age, parity, and social class were significantly higher in infants of mothers born in Pakistan and lower in those of mothers born in Bangladesh. The ratio for infants of Caribbean mothers was significantly higher when adjusted for maternal age. Ratios for infants of Indian and east African mothers did not show significant differences after standardisation. An important finding was a low incidence of sudden infant death in infants of Asian origin. This was paralleled by lower mortality from respiratory causes. During 1975-85 postneonatal mortality in all immigrant groups except Pakistanis fell to a similar or lower rate than that in the United Kingdom group; Pakistanis showed a persistent excess. During 1984-5 several immigrant groups (from the Republic of Ireland, India, west Africa, and the Caribbean) recorded an increase in postneonatal mortality. Surveillance of postneonatal mortality among ethnic communities should be continued, and research is needed to identify the causes underlying the differences.     

Fertility and legal abortion in England and Wales: performance indicators for family planning services.

The relation between fertility rates and legal abortion rates was investigated in a sample of health authorities in England and Wales to see how these varied. Total period fertility rates and total period legal abortion rates were derived from the average number of live births or legal abortions that would be experienced per woman if women experienced the age specific rates of the year in question throughout their childbearing years. The sample of 30 health authorities was selected by taking the districts with the highest and lowest fertility rates in each English region and in Wales in 1986. Total period fertility rates varied from 1.37 in Riverside to 2.42 in Tower Hamlets, while abortion rates varied from 0.25 in East Yorkshire to 0.99 in Riverside. When the two rates were added to provide a potential fertility rate it became clear that some districts with similar potential fertility rates had very different underlying component rates. Such comparisons can be used for service monitoring, indicating the need for better abortion and family planning services in districts with high fertility rates and for better family planning services in those with high abortion rates.     

Patterns of mortality among migrants to England and Wales from the Indian subcontinent.

Causes of deaths in immigrants to England and Wales from the Indian subcontinent were assessed by ethnic subgroup. Observed and expected deaths for 1975-7 were aggregated to calculate proportional mortality ratios. Observed mortality due to infective and parasitic diseases, endocrine diseases (notably diabetes), diseases of the circulatory system (notably ischaemic heart disease and cerebrovascular disease, in males), and diseases of the digestive system (notably cirrhosis of the liver) exceeded expected mortality. Fewer than expected deaths were due to malignant neoplasms (notably lung cancer and chronic bronchitis); proportional mortality ratios for cancer were lower for Hindu groups than for Moslems and were lowest for Punjabis. Mortality due to ischaemic heart disease, high in all groups, was highest in Moslems. Significantly more Punjabi males died from cerebrovascular disease and cirrhosis of the liver. Diabetes was commonest among Gujaratis. The variation seen in the patterns of mortality in the different ethnic groups indicates the need for further epidemiological and health service research centred on these communities.
