Census of neonatal transfers in London and the South East of England.

OBJECTIVES: To determine the number and characteristics of inter-hospital transfers of newborn infants in London and the South East of England. DESIGN: Prospective census of neonatal transfers over a three month period. SETTING: Transfers between the 53 hospitals that provide care for newborn infants within the former Thames regions. DATA SOURCES: Census returns from participating neonatal units. MAIN OUTCOME MEASURES: Number, timing, and hours of staff time spent on transfers. Gestation, birth weight, and reason for transfer of the baby. Time elapsed between request and retrieving team departing and arriving with patient. RESULTS: A daily average of 2.7 urgent, 3.5 elective, and 0.7 short term transfers took place during the census period. The most common reason for urgent transfer was neonatal surgery. Neonatal unit staff spent an average of 21 hours a day off their units accompanying transfers each day. It took over four hours for 90% of ambulances to set off with the retrieving team and over six hours for 90% of teams to reach the baby. CONCLUSIONS: During the census period, services for the transport of neonates in London and the South East of England involved long delays and used appreciable amounts of staff time. It is likely that a small number of dedicated neonatal transfer teams could meet the needs identified in this census more effectively than the 53 hospitals currently involved.

The prevalence and characteristics associated with parent-infant bed-sharing in England.

AIMS: To investigate the characteristics of parent-infant bed-sharing prevalence in England. METHODS: Data on night-time sleeping practices from a two year, local, longitudinal study and a three-year, national, cross-sectional study were obtained. A total of 261 infants in North Tees were followed up at 1 and 3 months of age, as were 1095 infants aged 1 week to 1 year from five English health regions. RESULTS: Data from both studies found that almost half of all neonates bed-shared at some time with their parents (local = 47%, 95% CI 41 to 54; national = 46%, 95% CI 34 to 58), and on any one night in the first month over a quarter of parents slept with their baby (local = 27%, 95% CI 22 to 33; national = 30%, 95% CI 20 to 42). Bed-sharing was not related to younger mothers, single mothers, or larger families, and was not more common in the colder months, at weekends, or among the more socially deprived families; in fact bed-sharing was more common among the least deprived in the first months of life. Breast feeding was strongly associated with bed-sharing, both at birth and at 3 months. Bed-sharing prevalence was uniform with infant age from 3 to 12 months; on any one night over a fifth of parents (national = 21%, 95% CI 18 to 24) slept with their infants. CONCLUSION: Bed-sharing is a relatively common practice in England, not specific to class, but strongly related to breast feeding.

Evaluation of the National Congenital Anomaly System in England and Wales.

OBJECTIVE: To evaluate the National Congenital Anomaly System (NCAS). METHODS: The NCAS in England and Wales based at the Office for National Statistics and the various regional registers that exchange data with it were examined, based on guidelines for evaluating public health surveillance systems, published by the Centres for Disease Control (CDC). Data relating to congenital anomaly notifications received from 1991 to 2002 were analysed. MAIN OUTCOME MEASURES: The main outcome measures were based on CDC standards and included the level of usefulness of the system, simplicity, flexibility, data quality, acceptability, sensitivity, representativeness, timeliness, and stability of the system. RESULTS: The NCAS has two main tiers: the "passive" system of voluntary notifications and the anomaly registers, but many reporting sources within these. It receives about 7000 notifications a year. It is inflexible and has variable data quality. The voluntary nature of reporting affects the system's acceptability. The sensitivity as compared with two regional registers (Trent and Wales) is about 33%. The congenital anomaly registers reporting to the NCAS achieve high levels of coverage and completeness. From 2003, they cover 42% of all births and account for the major proportion of the notifications. CONCLUSIONS: The NCAS serves the important function of monitoring birth defects in England and Wales, but is not currently operating in a timely or effective way. It should be adapted to meet its main objectives more effectively. More regional anomaly registers should be instituted and existing registers supported through central funds.

How protective is breast feeding against diarrhoeal disease in infants in 1990s England? A case-control study.

AIMS: To assess the effect of several measures of infant feeding on diarrhoeal disease, and whether these effects vary according to markers of social deprivation. METHODS: Case-control study of diarrhoeal disease cases presenting to 34 general practices in England. Controls were stratified on age group, area deprivation index for the practice, and whether or not the practice was in London. Data were available on 304 infants (167 cases and 137 controls). RESULTS: After adjustment for confounders, breast feeding was associated with significantly less diarrhoeal disease. Associations were striking even in infants aged > or = 6 months. They did not vary by social class, but were greater in those living in rented council accommodation and in more crowded households. The effect of receiving no breast milk was stronger in more deprived areas than in less deprived areas. The effect of not receiving exclusive breast milk was stronger in more deprived areas than in less deprived areas. In formula fed infants, there was significantly more diarrhoeal disease in those not sterilising bottles/teats with steam or chemicals. The protective effect of breast feeding did not persist beyond two months after breast feeding had stopped. CONCLUSIONS: Breast feeding protects against diarrhoeal disease in infants in England although the degree of protection may vary across infants and wear off after breast feeding cessation. Education about the benefits of breast feeding and the risks of inadequate sterilisation should be targeted at carers in deprived areas or households.

Trends in prevalence and survival of very low birthweight infants, England and Wales: 1983-7.

Between 1983 and 1987 over 99% of all infants born in England and Wales had their birth weights recorded when the birth was registered. Trends in occurrence and one year survival of those who weighed under 1500 g at birth have been calculated in 100 g groups, separately for single and multiple births. By 1987 singleton live births in England and Wales who weighed between 700 and 799 g had a 43% chance of surviving to 1 year compared with a 32% chance five years earlier; those who weighed 800 to 899 g had a 55% chance compared with 46%. The absolute number of survivors weighing between 500 and 999 g at birth increased by nearly 50% between 1983 and 1987, and there was a 30% increase overall in survivors weighing less than 1500 g.

Social environment and height: England and Scotland 1987 and 1988.

This study was designed to investigate the social characteristics associated with the height of primary schoolchildren aged from 5 to 11. Data were analysed for 8491 representative sample children measured in England and Scotland in 1987 and 1988 and 3203 inner city children measured in England in 1987. Height was negatively associated with social class but the association was not significant after allowing for biological variables. A negative gradient of height with size of sibship was evident in white children but was less so in Afro-Caribbean and Asian children. The individual associations of 11 different environmental characteristics were examined after allowing for biological factors and size of sibship. Consistent associations with height included a negative gradient of height with increasing latitude and an association of taller stature with increasing maternal age. A social class gradient in height is accounted for by associations with biological factors, particularly the parental heights; environmental attributes are weakly associated with height after allowing for biological factors.

Trends in growth in England and Scotland, 1972 to 1994.

AIM: To monitor the growth of 5 to 11 year old English and Scottish children from 1972 to 1994. No similar data are available from any other study. DESIGN: Mixed longitudinal. SUBJECTS: In England 7000 children were sampled in the first year, falling to 5000. In Scotland the original sample was 2000 but this was enlarged later to 3500. MAIN OUTCOME MEASUREMENTS: Height, weight, weight for height index, and triceps skinfold thickness. RESULTS: Height of English children in most age groups increased by more than 1 cm and by more than 2 cm in Scotland during the period 1972 to 1994. Triceps skinfold measurement increased by almost 8% in 7 year old English boys and by 7% in 7 year old girls. In Scotland triceps skinfold measurement increased by nearly 10% in 7 year old boys and by 11% in 7 year old girls. Weight for height index followed a similar pattern. CONCLUSION: Children in England and Scotland are becoming taller for a given age. The increases in fatness indicate an urgent need for realistic interventions for reductions in obesity in the whole population. As weight for height index is less sensitive than skinfold thickness we recommend triceps and subscapular skinfold thickness measurements for monitoring obesity in children.

Invasive pneumococcal disease in England and Wales: what is the true burden and what is the potential for prevention using 7 valent pneumococcal conjugate vaccine?

BACKGROUND: The annual reported incidence rates for laboratory confirmed invasive pneumococcal disease (IPD) underestimate the true burden of invasive disease attributable to pneumococcal infection. AIMS: To estimate the proportion of "unspecified" mortality of infectious cause in infants and young children aged 1 month to 4 years reported by the Office for National Statistics (ONS) in England and Wales that could reasonably be attributed to IPD, thereby revising the total number of deaths per year potentially attributable to IPD, and producing a more accurate figure for the number of deaths that may be prevented by a programme of pneumococcal conjugate vaccination. METHODS: Polymerase chain reaction, latex agglutination, and other alternate methodologies to microbiological culture have been applied in various studies to the detection of Streptococcus pneumoniae. Some of these tests have been shown to be more sensitive indicators of pneumococcal infection. In our analysis the implications of these tests were applied theoretically to the "unspecified" clinical deaths caused by septicaemia, meningitis, and pneumonia reported by the ONS, with a 20% correction/reduction factor for nasopharyngeal carriage which these sensitive tests may coincidentally detect. RESULTS: The ONS reported an average of 13 deaths per year (1989-99) in infants and children aged 1 month to 4 years caused by pneumococcal septicaemia, meningitis, or pneumonia. By applying the rates for the more sensitive tests to the most recent ONS "unspecified" mortality data available (1999), the actual annual number of deaths caused by IPD in the age group 1 month to 4 years is shown to be at least as high as 43. CONCLUSIONS: The mortality as a result of IPD in infants and young children may be at least three times the reported rate. The 7 valent pneumococcal conjugate vaccine may have the potential to prevent up to 26 (61%) of the IPD deaths per year in infants and young children in England and Wales alone.

Ascertainment of children with congenital cataract through the National Congenital Anomaly System in England and Wales.

BACKGROUND/AIMS: Congenital ocular anomalies contribute significantly to childhood visual morbidity, with congenital cataract being a major cause of visual impairment throughout the world. As in many other countries, a National Congenital Anomaly System (NCAS) exists in England and Wales to monitor the frequency of ocular and other anomalies in order to identify new public health hazards and inform aetiological research. The aim of this study was to assess level of ascertainment by the NCAS of children with congenital cataract. METHODS: Using independent ophthalmic and paediatric national active surveillance schemes, all infants (< or =1 year) newly diagnosed with congenital and infantile cataract in England and Wales in 1 year from September 1995 were identified. These notifications were compared with those made independently to the NCAS during the same period. The proportion of cases identified by the active surveillance schemes and also notified to the NCAS was determined. RESULTS: 10% (15/149) of eligible children with newly diagnosed congenital or infantile cataract were actually notified to the NCAS. A higher proportion of those diagnosed as neonates (16%, 14/85) than in later infancy (2%, 1/64) was ascertained through the NCAS. There is a need for better verification of notifications and reported information in the NCAS. CONCLUSION: Currently, ascertainment of congenital cataract through the NCAS is low and the system is likely to be insensitive to small but important changes in risk factors for this disorder. This limits its use for monitoring secular and other trends in ocular anomalies. Strategies to improve its future use are discussed, including enhancing the awareness and participation of ophthalmic professionals involved in managing children with anomalies.

A prospective study of injuries and training amongst the England 2003 Rugby World Cup squad.

OBJECTIVES: To assess the aetiology, incidence, severity, and causes of injuries to England rugby union players during preparation for and participation in the 2003 Rugby World Cup. METHOD: A 63 week prospective design was employed to study the training practices and injuries of England rugby players. The team physician reported all training and match injuries and provided details of the location, diagnosis, severity, and mechanism of each injury. The team fitness coach reported details of the number and duration of training sessions and the time dedicated to rugby and conditioning training. Players' stature, body mass, and skinfolds were measured at the beginning and end of the study period. RESULTS: The overall incidence of injury was 17 injuries/1000 h of exposure (match: 218 injuries/1000 h; training: 6.1 injuries/1000 h). The major locations of injuries were the lower (60%) and upper (17%) limbs and the most common diagnoses were muscle and tendon (50%) and joint (non-bone) and ligament (41%) injuries. The highest incidences of match injuries occurred whilst being tackled (50 injuries/1000 h) and in a ruck or maul (35 injuries/1000 h), whilst the greatest incidences of training injuries occurred during endurance running (24 injuries/1000 h) and contact activities (20 injuries/1000 h). Players' average body mass increased and skinfold measurement decreased significantly over the study period. CONCLUSIONS: The incidence of match injuries at international level was found to be higher than previously reported. The tackle, ruck, and maul elements of match play and the endurance running and contact elements of training presented the highest risk of injury for all players.

Regional variations in the incidence of upper urinary tract stones in England and Wales.

Data from the Hospital In-patient Enquiry were used to define the regional patterns of hospital discharge rates for upper urinary tract stones and renal colic in England and Wales. By combining the rates for stones and colic, and by distinguishing emergency from planned admissions, the biases produced by repeated admissions of the same patient and by regional variations in diagnosis and coding may be reduced. There are regional variations in incidence of upper urinary tract stones: Wales and the southern regions of England have a generally higher incidence than northern regions. These variations may be related to regional differences in diet or occupation; or they may partly depend on associations between stone incidence and atmospheric temperature, exposure to ultraviolet irradiation, and hardness of drinking water.

Comparison of central nervous system malformations in spontaneous absortions in Northern Ireland and south-east England.

A study of 1140 pregnancies ending in spontaneous abortion disclosed a central nervous system (CNS) malformation in 4.9% of all complete conceptuses. Life-table analysis suggested that the incidence of CNS malformations is 16/1000 at the beginning of the eighth week of gestation. It was also estimated that only one-fifth of these infants are born alive, 41% being aborted spontaneously and 38% stillborn. A hypothesis that differences in the incidence of CNS malformations result from area differences in the mortality rate of malformed embryos and fetuses was examined by comparing the findings in Northern Ireland, an area of high incidence, with those in south-east England, an area of low incidence. In Northern Ireland 4.6% of complete conceptuses had a CNS malformation compared with 3.0% in south-east England, but the difference was not statistically significant. There is no evidence that in Northern Ireland a lower mortality rate among malformed fetuses and embryos is responsible for the high incidence of malformation at birth. The geographical variation of CNS malformations in the United Kingdom still awaits explanation.

Contribution of general practitioner hospitals in England and Wales.

A survey of a one-in-seven sample of general practitioner hospitals in England and Wales, performed to determine the contribution they make to overall hospital work load and the attitudes of the general practitioners working in them, showed that 3% of acute hospital beds in England and Wales were in general practitioner hospitals, which provided initial hospital care for up to 20% of the population. Altogether 16% of general practitioners and 22% of consultants were on the staffs, and they coped with more than 13% of all casualties, 6% of operations, and 4% of x-ray examinations. Nearly a million casualties were treated at no cost to the National Health Service. Twenty new district general hospitals would be needed to cope with the work load currently dealt with by general practitioner hospitals. The results of this survey indicate that these smaller hospitals deal efficiently and cheaply with their work load, and that morale is high. General practitioner hospitals could have an important part to play in providing certain types of care, but there are no financial incentives to enable general practitioners to realise this potential fully.

Incidence of malignant melanoma of the skin in England and Wales and its relationship to sunshine.

In most of England and Wales the incidence of malignant melanoma of the skin has risen rapidly in recent years, especially in women. Mean incidences in the 14 English health regions and Wales correlated negatively with latitude and positively with hours of sunshine, suggesting that exposure to sunshine was an important causal factor. Male and female incidences within a region tended to show similar yearly fluctuations, implying a common factor affecting the incidence in both men and women with a short latent period of action. This factor may be exposure to sunshine, which may cause melanoma after an induction period of about two years; for women the incidence of melanoma in the regions of England and Wales correlated positively with hours of sunshine two years earlier.

First admissions to psychiatric hospitals in south-east England in 1976 among immigrants from Ireland.

Irish male immigrants had twice and female immigrants 1.7 times the expected number of first admissions to psychiatric hospitals in south-east England in 1976 when the expected number was based on the age- and sex-standardised rates of first admission of the population born in the United Kingdom living in the region. Admissions for alcoholism and alcoholic psychosis were five times higher in men and four times higher in women, and for schizophrenia 2.4 times as high in both sexes, as expected from these rates. When the expected number of first admissions was based on the age- and sex-standardised rates among Irish people living in Ireland the immigrants had fewer admissions than expected. Among migrants from Northern Ireland the number of first admissions was significantly greater than expected. Admissions for alcoholism and alcoholic psychosis in men and women combined were seven times the expected number based on the UK rates. There was no significant difference in the proportion of single people between the Irish immigrants and people born in the UK. Marital state, socioeconomic group, and occupation may partly account for the high number of admissions for alcoholism and schizophrenia among Irish people living in south-east England.

Communicable disease associated with milk and dairy products in England and Wales 1951-80.

In England and Wales between 1951 and 1980 233 reported outbreaks of communicable disease attributed to milk or dairy products affected nearly 10 000 people, of whom four died. Tuberculosis and brucellosis have been controlled, but milk-borne outbreaks of salmonellosis and campylobacter enteritis due to raw or defectively pasteurised milk are common and may be increasing in number. Universal heat treatment of milk is an effective preventive measure, and it is regrettable that the continued sale of untreated milk is to be permitted in England and Wales.

Seasonal variation and time trends in childhood asthma in England and Wales 1975-81.

In England and Wales hospital admissions for childhood asthma almost trebled over the period 1975-81. This may have reflected a true increase in the incidence of acute asthma, a swing from primary to hospital care, or both. The trend was not due to a change in diagnostic fashion. Monthly admissions showed a pronounced seasonal variation with fewest admissions in winter, rising in spring and early summer to peak in the autumn. A deep admission trough was present in August. The monthly admission profile was very similar throughout England and Wales, suggesting that major "trigger" factors were responsible.

Occupational mortality among women in England and Wales.

Occupational mortality in women who died in England and Wales from 1970 to 1972 was analysed. Many of the associations found were consistent with those that have been described for men, with high mortality ratios for cirrhosis in barmaids and publicans, for suicide in the medical and allied professions, and for respiratory disease in textile workers. Parity is a determinant of patterns of disease in working women, and the relative excess of cancer of the breast, ovary, and uterine body in professional and clerical workers probably reflected the high proportion of nulliparous women in these groups. Other associations may have reflected true occupational hazards; one observation requiring further attention was the high proportional mortality ratio for anaemia in textile and clothing workers. The description of the occupational mortality among women in England and Wales is hampered by the incomplete recording of information about women's occupations at registration of death. As women now constitute 40% of the workforce, often have their own specific occupations, and possibly also have their own diseases related to specific occupations it is time for the registrar's guidelines on the recording of women's occupation--last reviewed at the beginning of this century--to be revised.
