Infants in Trinidad excrete more 5-L-oxoproline (L-pyroglutamic acid) in urine than infants in England: an environmental not ethnic difference.

The demand for glycine to satisfy normal growth during early life is considerable and most has to be made endogenously. The extent to which adequate glycine is available can be assessed by measuring the urinary excretion of 5-L-oxoproline. The excretion of 5-L-oxoproline at 6 weeks of age for infants in Trinidad of African, Indian or mixed parentage (398 mumol/mmol creatinine) was significantly greater than for infants born in England of Caucasian parentage (194 mumol/mmol creatinine). There was no relationship between 5-L-oxoproline excretion and either sex or pattern of feeding. There were significant inverse relationships between 5-L-oxoproline/creatinine and birth weight, and head circumference either at birth or 6 weeks of age, suggesting that limited availability of glycine is associated with poorer growth before and after birth. For a group of infants born in England of Indian parentage, excretion of 5-L-oxoproline (155 mumol/mmol creatinine) was not different to infants of Caucasian parentage, but significantly less than infants born in Trinidad. The demonstration that 5-L-oxoproline/creatinine was similar in infants born in England, regardless of parentage, shows that the differences between England and Trinidad are related to environment and are unlikely to be accounted for by genetic differences or ethnicity.

Observations on the incidence of herds with non-visible lesioned tuberculin test reactors in south-west England.

The herd incidence of confirmed Mycobacterium bovis infection in cattle in the south-west of England has been approximately ten times that of the remainder of England and Wales; this greater incidence has been attributed to infection from badgers. The incidence of herds with only non-visible lesioned tuberculin test reactors, from which M. bovis was not isolated, has also remained higher in the south-west region. The incidences of these latter unconfirmed incidents were compared in parishes in the south-west region in which M. bovis in cattle had been confirmed, and those where M. bovis had not been confirmed, for the period 1979-83. This analysis was carried out both for those parishes in which herds had been subjected to annual tuberculin testing and for those subjected to biennial tuberculin testing. The incidence of unconfirmed incidents was significantly higher in parishes in which confirmed incidents had occurred, and this difference was found in both the annual and biennially tested parishes. The relative risks for the incidence of unconfirmed incidents in annually and biennially tested parishes were 1.89 and 2.56, respectively. The incidence of unconfirmed incidents in biennially tested parishes was lower than in annually tested parishes. The incidence of non-specific tuberculin test reactor herds was estimated from tuberculin test results in the eastern region of England during a period when tuberculosis was not confirmed in cattle. A comparison of this incidence and that of unconfirmed incidents in the south-west region suggests that approximately 70% of the unconfirmed incidents in the south-west were related to exposure to M. bovis. The results of the analyses indicate that unconfirmed incidents cannot be completely ignored in epidemiological analyses and studies of bovine tuberculosis in the problem areas of the south-west region of England.

The changing epidemiology of diagnosed prevalent HIV infections in England: greatest impact on the London environs.

Data from the 1997-2004 Surveys of Prevalent HIV Infections Diagnosed were analysed by three geographical areas of residence and treatment to describe the heterogeneous growth of the HIV epidemic in England and provide projections to 2007. Between 1997 and 2004, the number of diagnosed HIV-infected adults resident in England increased by 163% (14,223 to 37,459). Within the 'London environs' the increase was 360% (742 to 3411), within the rest of England 219% (4417 to 14,088) and within London 120% (9064 to 19,960). By 2004, the London environs had the largest proportion of infections acquired through heterosexual sex (and in particular women) and the most recently diagnosed population. Projections indicate over half of diagnosed HIV-infected adults will live outside London by 2007. The epidemiology of diagnosed HIV infection within the London environs is likely to be a predictor of future trends in England overall.

The duration and magnitude of influenza epidemics: a study of surveillance data from sentinel general practices in England, Wales and the Netherlands.

Weekly incidence data for influenza-like illness, routinely collected in sentinel general practices in England and Wales and in the Netherlands over 10 winter periods (week 37 in one year to week 20 in the next, 1987/1988-1996/1997) were examined in conjunction with matching virus isolate data to define epidemic periods of influenza in the two countries. We first defined the background rates of recording influenza-like illness which occurred at times when only sporadic or no isolations of virus were reported. The background rates were similar in the two networks with mean weekly incidence in England and Wales of 28.1 per 100,000 (all ages) and in the Netherlands 29.8. Epidemic periods defined as lying above the upper 95% confidence level of the background rate lasted on an average of about 10 weeks. Once epidemics were recognised, peak incidence was generally achieved within 4 weeks. The excess population (all ages) consulting general practitioners during influenza epidemic periods was calculated from the difference between the observed and background incidence rates, and expressed as a percentage of the total population. In the 10 periods surveyed, the percentage of the population consulting and diagnosed with influenza-like illness in England and Wales ranged from 0.4% in 1991/1992 to 1.7% in 1989/1990 and in the Netherlands from 0.5% in 1990/ 1991 to 2.1% in 1989/1990. The duration and epidemic periods were broadly similar in the two countries though the excess consulting population during the 10 epidemics studied averaged 0.85% in England and Wales compared with 1.39% in the Netherlands. There were substantial differences between the two countries in the impact of influenza in individual years, as measured in the consulting population even though the predominant virus (sub)types were similar.

Kaposi's sarcoma in England and Wales before the AIDS epidemic.

The epidemiological features of Kaposi's Sarcoma (KS) incidence in England and Wales in the period 1971-1980 are reviewed. The epidemiology of KS in England and Wales in this period is distinct from that associated with the AIDS epidemic. The incidence was probably very low compared to other Western countries, there was little male excess, and no indication, based on marital status data, of a raised incidence in male homosexuals. Half the cases registered were in people born outside the UK. The region of birth distribution in these migrants reflected the known pre-AIDS geographic distribution of KS and also pointed to high risks in those from Middle Eastern countries and the Caribbean. The very low incidence rates of KS in natives of England and Wales suggests that the background prevalence of the causative agent for KS was low in England and Wales prior to the AIDS epidemic.

Cancer mortality in Indian and British ethnic immigrants from the Indian subcontinent to England and Wales.

Risk of cancer mortality from 1973 to 1985 in persons born in the Indian subcontinent who migrated to England and Wales was analysed by ethnicity, and compared with cancer mortality in the England and Wales native population, using data from England and Wales death certificates. There were substantial highly significant raised risks in Indian ethnic migrants for cancers of the mouth and pharynx, gall bladder, and liver in each sex, larynx and thyroid in males, and oesophagus in females. There were also substantial raised risks in these migrants of each sex for non-Hodgkin's lymphoma and myeloma. For the mouth and pharynx, and liver in each sex, and gall bladder in females, there were also raised risks of lesser magnitude in British ethnic migrants. For colon and rectal cancer and cutaneous melanoma in each sex, ovarian cancer in women and bladder cancer in men, there were appreciable significantly reduced risks in the Indian ethnic migrants not shared by those of British ethnicity. Appreciable raised risks in British ethnic migrants not shared by those of Indian ethnicity occurred for nasopharyngeal cancer in males, soft tissue malignancy in both sexes and non-melanoma skin cancer in males. In migrants of both ethnicities there were appreciable significantly raised risks in each sex for leukaemia and decreased risks in each sex for gastric cancer, for lung cancer except in females of British ethnicity and in males for testicular cancer. The results suggest the need for public health measures to combat the high risks of oral and pharyngeal cancers and liver cancer in the Indian ethnic immigrant population of England and Wales, by prevention of betel quid chewing and hepatitis transmission respectively. The data also imply that early exposures or early acquired behaviours in India, or exposures during migration, may increase the risk of leukaemia and reduce the risks of gastric and testicular cancers in the migrants irrespective of their ethnicity. Aetiological studies would be worthwhile to investigate the reasons for the sizeable decreased risk of colon and rectal cancer and increased risk of gall bladder cancer in each sex and the increased risk of thyroid and laryngeal cancer in males and oesophageal cancer in females of Indian ethnicity but not of British ethnicity who have migrated from the Indian subcontinent.

Back to the bedpans: the debates over preregistration nursing education in England.

AIMS OF THE PAPER: This paper aims to examine the recent debates in both the general and professional press over the future of preregistration education in England, in the light of the sociological literature on the professions, and the nature of nursing knowledge. The literature on the Project 2000 reforms, although by now well worn, will also be discussed briefly. BACKGROUND/RATIONALE: The bulk of nursing education in England moved into higher education in the 1990s. Unlike other higher education in England, it is not funded by the Department for Education and Employment, but commissioned by the National Health Service (NHS), to which it is expected to be highly responsive. DESIGN/METHODS: This paper is based on a brief literature survey, plus policy documents and media reports. FINDINGS/CONCLUSION: It will be argued that the process of professionalization is not a straightforward one, and has its potential for reversals of fortune, and that nursing occupies a marginal place in higher education in England.

Estimation of the risk of hepatitis B virus, hepatitis C virus and human immunodeficiency virus infectious donations entering the blood supply in England, 1993-2001.

BACKGROUND AND OBJECTIVES: The frequency of hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV) infectious donations entering the blood supply in England is too low to monitor using observational studies. The expected frequency of infectious donations can be estimated and these estimates may be used to contribute to monitoring of blood safety and used in the design of strategies to decrease the risk of transfusion-transmitted infections. MATERIALS AND METHODS: The prevalence and incidence of hepatitis B surface antigen (HBsAg), and antibodies to HCV and HIV (anti-HCV and anti-HIV, respectively) in donors in England, between 1993 and 2001, were used together with data about the length of negative 'window-periods' of current assays for each of these markers and data about test performance, to estimate the number of infectious donations that enter the blood supply. The risks were calculated separately for donations from new donors and from repeat donors, and for the three time periods 1993-95, 1996-98 and 1999-01. RESULTS: The estimated frequency of infectious donations entering the blood supply in England, between 1993 and 2001 was 1 in 260,000 for HBV and 1 in 8 million for HIV. For HCV, the frequency of infectious donations was 1 in 520,000 during 1993-98 and fell to 1 in 30 million during 1999-2001 when all donations were tested for HCV RNA. The frequency of HBV- and HCV-infectious donations entering the blood supply fell over these 9 years: the frequency of HIV-infectious donations remained essentially unchanged. The risk from donations from new donors was found to be approximately sevenfold higher than the risk from donations from repeat donors. CONCLUSIONS: The risks of HBV-, HCV- or HIV-infectious donations entering the blood supply in England are very low, and have decreased since 1993. Although the accuracy of these estimates is imperfect, mainly owing to uncertainty in some assumptions and to small numbers of infections, they provide some quantification of the risk of HBV, HCV or HIV transmission by transfusion, and allow comparison of the magnitude of these risks for each infection and over time. The methods we have used have been developed and improved from previously published methods.

Long-term trends in home advantage in professional team sports in North America and England (1876-2003).

Home advantage is quantitatively defined and calculated for each season since the start of the main professional sports in North America and England. Over 400,000 games are analysed. The leagues represented are the National League (1876-2002) and American League (1901-2002) for baseball, the National Hockey League (1917-2003) for ice hockey, the National Football League (1933-2002) for American football, the National Basketball Association (1946-2003) for basketball, and the four levels of professional football, formerly called the Football League, in England (1888-2003). Problems caused by unbalanced playing schedules are considered. The results are presented graphically to show long-term trends and sudden changes. The highest levels of home advantage for all sports were in their early years of existence. Home advantage in ice hockey, basketball and football in England has declined over the last two decades. In baseball there has been very little change over the last 100 years, with home advantage consistently lower than in other sports. There was a large drop in home advantage in football in England following the 7-year suspension of the league during the Second World War. The trends and changes provide some evidence that travel and familiarity contribute to home advantage, but little in support of crowd effects.

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.

Suicide and self-poisoning in three countries--a study from Ireland, England and Wales, and Denmark.

Because it has been suggested that both the frequency of deliberate self-poisoning and the characteristics of those who self-poison differ between Ireland, and England and Wales on the one hand and Denmark on the other we have examined self-poisoning rates and suicide rates in these three countries. Higher self-poisoning rates were found for England and Wales than for the other two countries below age 35. After this age self-poisoning rates decline in both England and Ireland but female rates continue to rise in Denmark up to age 45. Danish suicide rates are conspicuously higher than those of both England and Wales, and Ireland. Because combined death rates for suicide, undetermined and accidental deaths diminish but do not remove the differences between countries it is suggested that the Danish suicide death rate reflects a genuinely higher rate of suicide in that country.

Mortality of hepatitis B surface antigen-positive blood donors in England and Wales.

BACKGROUND: Large population-based cohort studies in areas of high hepatitis B virus (HBV) prevalence have provided the evidence establishing hepatitis B surface antigen (HBsAg) carriage as a risk factor for hepatocellular carcinoma (HCC) and liver disease. Fewer studies have examined this in Western countries, where both HBV infection and carriage are less common and transmission patterns differ. This is the only prospective population-based study to examine this relationship in Europe. METHODS: In all, 2681 male and 977 female blood donors in England and Wales, found to be HBsAg positive during routine blood-donation screening, were followed up from recruitment in 1970-1982 to December 1999 and their cause-specific mortality was analysed. This was compared with that of the general population of England and Wales. RESULTS: During a mean of 22 years of follow-up, 17.4% of the 420 deaths were due to HCC or liver disease. There were 20 deaths from HCC in male HBsAg carriers, representing a significantly high standardized mortality ratio (SMR) compared to the male population of England and Wales of 26 (SMR = 26.26; 95% CI: 16.04- 40.54). The HCC incidence rate in males was 33.5 per 100 000 person years and 4.4 per 100 000 person years in females. Men had 8.5 (SMR = 8.50; 95% CI: 6.25- 11.31) and women had 3.9 times the risk of death from liver disease (SMR = 3.89; 95% CI: 1.26-9.09). The risk of circulatory disease deaths was reduced in both males and females. There was a significant increased risk of non-Hodgkins lymphoma that was not apparent in the first decade of follow-up. The increased risk of HCC and liver disease in men fell with follow-up. CONCLUSION: Hepatitis B surface antigen carriage is a significant risk factor in England and Wales for both liver disease and HCC mortality. However, this risk has declined with duration of follow-up. This could be due to natural reversion to HBsAg negativity or as a result of treatment and avoidance of other risk factors. The increased risk of non-Hodgkins lymphoma seen in longer follow-up is likely to be related to HIV infection acquired subsequent to recruitment.

The costs and effectiveness of surveillance of communicable disease: a case study of HIV and AIDS in England and Wales.

BACKGROUND: In England and Wales, surveillance of communicable disease is carried out and co-ordinated by the Public Health Laboratory Service (PHLS). The surveillance of HIV infection and AIDS is undertaken by the PHLS AIDS Centre at the Communicable Disease Surveillance Centre (CDSC). Epidemiological data derived from surveillance are not, however, a free good: they are a resource with an associated opportunity cost and should therefore be open to economic appraisal alongside other users of health care resources such as medical interventions. This paper assembles information on the current surveillance of HIV and AIDS in England and Wales, and explores methods for performing an economic evaluation of such activities. METHODS: An examination of the cost and effectiveness of the PHLS AIDS Centre's epidemiological surveillance mechanisms for HIV and AIDS in England and Wales was undertaken. The total costs of each component of surveillance of HIV and AIDS in England and Wales were calculated. Two categories of cost were estimated: peripheral costs incurred by reporters in reporting AIDS cases or HIV infections or by laboratories in collecting samples; and central costs incurred by the PHLS AIDS Centre in processing and analysing incoming data. Using these cost data and information from a cost-effectiveness register, the additional health gains that would have to be obtained from surveillance to make the programme broadly cost-effective in comparison with other accepted uses of health service resources were then estimated. RESULTS: In the financial year 1993-1994 the total costs of surveillance were estimated to be 1.4 million pounds. To avoid being considered relatively cost-ineffective at least 3.5 infections per annum need to be averted. To be considered favourably cost-effective, approximately 9.5 infections per annum need to be averted. CONCLUSIONS: In 1993-1994, expenditure on surveillance of HIV and AIDS accounted for less than 1 per cent of the total allocation of resources to the National Health Service for all HIV and AIDS activities. Given these cost estimates, the number of infections which surveillance would have to contribute towards preventing in order to be considered cost-effective is low.

Impact of paracetamol pack size restrictions on poisoning from paracetamol in England and Wales: an observational study.

BACKGROUND: About 500 drug poisoning deaths involving paracetamol (acetaminophen) occur every year in England and Wales. To reduce the number of deaths, regulations were introduced in 1998 to restrict the sale of paracetamol. In this paper, we evaluate the impact of these regulations. METHODS: Mortality data for England and Wales were provided by the Office for National Statistics. Deaths were defined as due to compound paracetamol (paracetamol in combination with another analgesic, a low dose opioid or other ingredients) or paracetamol only, with or without alcohol or other drugs. The Department of Health provided data on all hospital admissions with a primary diagnosis of paracetamol poisoning. RESULTS: Mortality rates for paracetamol only were similar for males and females, and decreased from about 4.5 to 2.8 per million between 1997 and 1999 and again from about 3.1 to 2.2 per million between 2001 and 2002. These falls may be attributable to random variation in the rates. Deaths involving compound paracetamol, which were not subject to the 1998 regulations, remained relatively constant over the study period. There was evidence of a decreasing trend in paracetamol only mortality rates and this followed overall trends for other drug poisoning excluding opioids and drugs of misuse. Hospital admissions due to paracetamol poisoning increased from about 27 000 to 33 000 between 1995/1996 and 1997/1998 and then decreased to 25 000 in 2001/2002. There were almost 50 per cent more admissions for females than males, with the highest admission rates amongst females aged 15-24 years old. CONCLUSIONS: Between 1993 and 2002, mortality rates and hospital admissions due to paracetamol poisoning declined. However, the contribution of the 1998 regulations to this decline is not clear. Paracetamol poisoning continues to be an important public health issue in England and Wales and represents significant workload for the NHS in England.

Visiting hours policies in New England intensive care units: strategies for improvement.

OBJECTIVE: Dying patients often feel isolated and alone, and restricted visiting hours in the intensive care unit (ICU) has been shown to increase anxiety and dissatisfaction in both critically ill patients and their families. Unrestricted visiting has been identified as a top-ten need by families of patients in the ICU. Because emotional distress experienced by patients and families may persist well beyond the ICU stay, an open visiting policy, by meeting the needs of patients and families, may improve the quality of end-of-life care in the ICU. This two-part study included a survey to determine the visiting hours policies of New England-area hospital ICUs, and nursing focus groups to describe challenges and barriers that nursing staff working in an open ICU have experienced and to provide solutions that will facilitate implementation of an open visiting hours policy. DESIGN: Two-part study: survey and focus groups. SETTING: ICUs in New England and one medical ICU in a tertiary care hospital. SUBJECTS: Registered nurses employed in medical ICUs. INTERVENTIONS: Adult ICUs in the six New England states were located using a library listing of all regional hospitals. A telephone questionnaire interview was used to ascertain visiting hours policies in each ICU. Six focus-group sessions were conducted with nursing staff who work in an urban, northeastern ICU with 8 yrs of experience with an unrestricted visiting hours policy. MEASUREMENTS AND MAIN RESULTS: A total of 171 hospitals completed the questionnaire (96%). From all ICUs surveyed, 62 (32%) had unrestricted, open visiting hours. Out of these, 57 (92%) were medical ICUs or mixed medical/surgical ICUs. Nursing staff identified three major areas of concern with an open visiting hours policy: space, conflict, and burden. Strategies for resolution that are either employed or advocated by nursing staff are described. CONCLUSIONS: The majority of ICUs in New England have restricted visiting hours. Only one third of ICUs have open visiting policies. Nursing concerns with an unrestricted ICU were identified and solutions were offered that may provide guidance for other ICUs considering adopting an open visiting hours policy.

New estimates of herpes simplex virus type 2 seroprevalence in England: 'high' but stable seroprevalence over the last decade.

OBJECTIVES: There have been few recent population-based herpes simplex virus type 2 (HSV-2) seroprevalence studies in England, but reports from the United States have indicated a 30% rise in HSV-2 seroprevalence between 1976 and 1994. This study aimed to ascertain trends in HSV-2 infection in England between 1991 and 2000. STUDY DESIGN: Anonymized serum residues collected through public health laboratories across England from individuals aged 16 to 64 years seeking health care through the National Health Service in 1991 (n = 2259) and 2000 (n = 3646) were tested for anti-HSV-2 IgG using the HerpeSelect 2 enzyme-linked immunosorbent assay IgG (Focus). RESULTS: In 9 sites across England, the age- and sex-standardized HSV-2 seroprevalence was 9.7% (95% confidence interval, 8.4-11.0%). Data from 4 sites common to both study years indicated no change in HSV-2 seroprevalence between 1991 and 2000. CONCLUSIONS: After adjustment for age, sex, and geographic location, there was no evidence of a change in seroprevalence between 1991 and 2000.

Identification and characterization of transmissible Pseudomonas aeruginosa strains in cystic fibrosis patients in England and Wales.

Most past studies of cross-infection with Pseudomonas aeruginosa among cystic fibrosis (CF) patients in the UK suggest that it is a rare occurrence. However, two recent reports of highly transmissible strains in patients in regional centres in England (Liverpool and Manchester) have raised questions as to the extent of the problem and prompted a nationwide survey to establish the distribution of P. aeruginosa strain genotypes among these patients. Isolates of P. aeruginosa were requested from over 120 hospitals in England and Wales and a sample size of approximately 20% of the CF patient population in each centre was recommended. In total, 1225 isolates were received from 31 centres (range 1 to 330). Single patient isolates were typed by SpeI macrorestriction and PFGE. A panel of strains of the common genotypes including representatives of reported transmissible strains was assembled and further characterized by fluorescent amplified fragment length polymorphism (FAFLP) genotyping. At least 72% of all patients harboured strains with unique genotypes. Small clusters of related strains were evident in some centres, presumably indicating limited transmission of local strains. The most prevalent strain was indistinguishable from that previously described as the 'Liverpool' genotype, and accounted for approximately 11% of patient isolates from 15 centres in England and Wales. The second most common genotype (termed Midlands 1) was recovered from 86 patients in nine centres and the third genotype, which matched closely the PFGE profile of Clone C, a genotype originally described in Germany, was found in eight centres and was isolated from 15 patients. A fourth genotype, identical to the published Manchester strain, was found in three centres. FAFLP analysis revealed some microheterogeneity among strains of the Liverpool genotype but all isolates of this genotype were positive by PCR for a strain-specific marker. These data suggest that cross-infection with P. aeruginosa has occurred both within and widely between CF centres in England and Wales. The two most common genotypes accounted for more than one-fifth of patients' isolates examined and transmissible genotypes were found in all but three centres studied. These results emphasize the need for continued surveillance of P. aeruginosa genotypes in CF patients to provide informed infection control policy in treatment centres.

Maternal mortality and manpower. Comparisons in relation to anaesthetists, obstetricians, and paediatricians in England and Wales and in Japan.

In 1982 maternal mortality in England and Wales was given seven per 100 000 compared to 18 per 100 000 total births in Japan. This represented 160 more deaths in Japan. Perinatal mortality rates were similar in England and Wales and Japan, being 11.3 and 10.1 per 1000 respectively. The prevalence of obstetricians and paediatricians per 100 000 total births are approximately similar in England and Wales and in Japan, whereas the rates for anaesthetists are five times less in Japan. In England and Wales, 13% of maternal deaths were related to anaesthetic misadventures, but the Japanese incidence is not known. However, more than 50% of anaesthetics for Caesarean sections in district hospitals in Japan are administered by obstetricians. A pilot study in Japan would be necessary to determine the precise role of anaesthetic provision on maternal mortality. Maternal mortality may prove a useful indicator of anaesthetic service deficiency.
