Avoidable factors contributing to death of children with head injury.

OBJECTIVE--To assess the incidence of potentially avoidable complications contributing to death of children with head injuries. DESIGN--Retrospective review of children who died with head injuries from 1979 to 1986 from data of the Office of Population Censuses and Surveys, Hospital Activity Analyses, case notes, coroners'' records, and necropsy reports. SETTING--District general hospitals and two regional neurosurgical centres in Northern region. RESULTS--255 Children died from head injury in the region, the mortality being 5.3 per 100,000 children per year. Head injury was the single most important cause of death in children aged greater than 1 year, accounting for 15% of deaths in children aged 1-15 years and a quarter for those aged 5-15 years. 121 Potentially avoidable factors possibly or probably contributing to death occurred in 81 children (32%). Half the children (125) died before admission, 27 of whom (22%) had potentially avoidable factors possibly or probably contributing to death, and 130 died after admission, 54 of whom (42%) had 93 such factors, which included failure of diagnosis or delayed recognition of intracranial haemorrhage or associated injury, inadequate management of the airways, and poor management of the transfer between hospitals. IMPLICATIONS--Regions should revise urgently their guidelines for optimal management and indications for neurosurgical referral to include children with severe head injuries and audit their systems of care for all patients with head injuries.     

Deaths in children with a diagnosis of acute appendicitis in England and Wales 1980-4.

Thirty five children died of acute appendicitis in England and Wales in 1980-4 compared with 204 in 1963-7. Thirteen of the 35 deaths in 1980-4 took place at home or on the day of admission to hospital before operation and a further 18 on the day of operation or the first day after it. Thirty one of the children had peritonitis. A third of the deaths were in children aged 0-4 years, and the hospital fatality rate in this age group was one death in 320 cases compared with one death in 4760 cases in children aged 5-14 years. The fall in the number of deaths between the 1960s and the 1980s was due to improvements in medical care, a reduction in the incidence of appendicitis, and changes in the age structure of the child population. Difficulty and delay in diagnosis and inadequate intravenous therapy are now the main factors contributing to death.     

Pasteurisation and the control of milkborne infection in Britain.

Infections carried in milk, particularly salmonellosis and campylobacter enteritis, have continued to feature in Great Britain in recent years. Less commonly reported infections included an outbreak in 1984 in England due to Streptococcus zooepidemicus, in which 12 people, eight of whom died, were admitted to hospital. The implementation of legislation in 1983 requiring heat treatment of cows'' milk for sale to the public reduced the incidence of milkborne infection in Scotland compared with previous years and compared with England and Wales, where, without legislative control, outbreaks continue to occur. Until compulsory pasteurisation is introduced throughout Britain and dairy farming communities can be persuaded to drink only heat treated milk outbreaks of milkborne infection will continue.     

Control of hydatid disease in Wales.

OBJECTIVES--To evaluate the success of the south Powys hydatid control programme by analysis of trends in cystic disease in humans and sheep and dog infestation. DESIGN--A review of hospital admissions for human hydatid disease in 1984-90, abattoir prevalence surveys of hydatid cysts in adult sheep, arecoline acetarsol and coproantigen surveys of prevalence of Echinococcus infestation in dogs. SETTING--All hospitals in England and Wales, three abattoirs, and dog populations in mid ands south east Wales. SUBJECTS--Residents of England and Wales admitted to hospital between 1984 and 1990 with a new diagnosis of human hydatid disease (International Classification of Diseases (ICD), ninth revision, code 122) acquired in the United Kingdom. RESULTS--The average annual incidence of human hydatid disease in Powys, mid-Wales, fell from 3.9x10(-5) in 1974-83 to 2.3x10(-5) in 1984-90. Age specific incidence rates in Wales declined over this period only in children, and no cases occurred in children (<15 years) in Powys. Two Welsh children who lived in Gwent and mid-Glamorgan were infected. Prevalence of hydatid cysts in old sheep from south Wales declined during the control period, but in 1993 prevalence of cysts was 13%. Prevalence of E granulosus infestation was zero in the control area in 1993, but it was 2.4% in Powys dogs outside the control area in 1989 and 9.2% in dogs in Gwent in 1991. CONCLUSIONS--Human hydatid disease has been successfully controlled in south Powys but cystic echinococcosis is still endemic in sheep in mid-Wales, and there is a focus of infection in humans, sheep, and dogs in the bordering areas of Gwent and mid-Glamorgan. There is considerable potential for an upsurge in human cases if control measures are relaxed.     

Mortality of bereavement.

The death rate of a group of 87 widowers and 279 widows was followed for two years from the death of their spouses. The life tables for England and Wales 1970-2 indicated that the expected number of deaths would be 6 men and 11 women. The actual numbers (9 men and 11 women, 5.5%) were not significantly different, though there were more widowers'' deaths during the first six months of bereavement. There was no significantly greater mortality among those whose spouses had died in hospital; but when this had occurred the health of the second spouse was likely to have been poorer than that of those whose spouses had died at home.     

Unrecognised HIV related deaths.

OBJECTIVES--To establish whether follow up of deaths from selected HIV related causes could increase the number of cases of HIV infection reported to the Public Health Laboratory Service Communicable Disease Surveillance Centre (CDSC), and to estimate the proportion of deaths among HIV positive men that occurred in men who were not known to be HIV positive at the time of death by the person who signed the death certificate. DESIGN--Follow up of draft death entries received by the Office of Population Censuses and Surveys on which one of 11 medical or external causes likely to be related to HIV was stated; letters were sent to the people who signed the certificates. The respondents were invited to report men known to have been HIV positive who were not already on the CDSC register. SETTING--England and Wales. SUBJECTS--Men aged 15-54 who died in February 1989 to July 1989 with one of the 11 selected HIV related diseases as cause of death on their death certificates. MAIN OUTCOME MEASURES--Number of men reported to the CDSC as a result of this follow up; estimate of excess deaths due to an HIV related cause; estimate of the proportion of excess deaths that occurred in those who were not known to be HIV positive at the time of death. RESULTS--Replies were received for 473 deaths (86%). Forty were for men known to have been HIV positive, 31 of whom had been reported to CDSC by the time they died; six were subsequently reported. The respondent did not know that the decreased was HIV positive for 20 (35%) of the 57 excess deaths in men for whom one of the medical causes was stated and 41 (93%) of the 44 excess deaths in men for whom one of the external causes was stated. CONCLUSION--Follow up of death registrations is not an efficient way of increasing the number of cases of HIV infection reported to CDSC. Between 35% and 60% of HIV positive people for whom certain causes are stated may be dying without HIV positivity having been diagnosed. There may be implications for those caring for people with these conditions and those who carry out postmortem examinations.     

Screening for hearing loss in childhood: a study of national practice.

A questionnaire survey of all health districts in England and Wales was carried out at the end of 1984 to document screening programmes for identifying hearing loss in childhood. The response rate was 81.3%. All districts performed distraction testing, all but nine aiming at doing so at 7-9 months of age. All districts tested children''s hearing at school, generally before 7 years of age. The number of times that children were screened both before school and at school varied considerably, from one to six times before school and one to six times at school. Few districts collected information that would allow them to make judgments about the efficiency of effectiveness of their screening programmes.     

Does the decline in child injury mortality vary by social class? A comparison of class specific mortality in 1981 and 1991.

OBJECTIVE: To examine whether the decline in child injury death rates between 1981 and 1991 varied by social class. DESIGN: Comparison of class specific child injury death rates for 1979, 1980, 1982, and 1983, with those for the four years 1989-92. SETTING: England and Wales. SUBJECTS: Children aged 0-15 years. MAIN OUTCOME MEASURES: Death rates from injury and poisoning. RESULTS: Death rates from injury and poisoning have fallen for children in all social classes. The decline for children in social classes IV and V (21% and 2% respectively), however, is smaller than that for children in social classes I and II (32% and 37%). As a result of the differential decline in injury death rates, socioeconomic mortality differentials have increased. In the four years 1979-80 and 1982-83 the injury death rate for children in social class V was 3.5 times that of children in social class I. For the four years 1989-92 the injury death rate for children in social class V was 5.0 times that of children in social class I. Poisson regression modelling showed that the trend in the decline in death rates across the social classes was unlikely to have arisen by chance alone. CONCLUSIONS: Socioeconomic inequalities in child injury death rates have increased. If these gradients persist, the Health of the Nation''s target is likely to be met for children in the non-manual social classes but not for those in the manual social classes.     

Avoidable factors contributing to death after head injury.

We reviewed 116 patients, known to have talked before dying after head injury, to discover factors which had contributed to death but which might have been avoided. All the patients were admitted to a neurosurgical unit and had a neuropathological post-mortem examination. One or more avoidable factors were identified in 86 patients (74%); an avoidable factor was judged certainly to have contributed to death in 63 patients (54%). The most common avoidable factor was delay in the treatment of an intracranial haematoma; others included poorly controlled epilepsy, meningitis, hypoxia, and hypotension. Changes in the management of patients with head injuries which reduce the incidence of avoidable factors should decrease mortality from this condition.     

Vertically transmitted HIV infection in the British Isles.

OBJECTIVE--To describe the epidemiology of vertically acquired HIV infection in the British Isles, the level of underreporting, the vertical transmission rate, and clinical spectrum of paediatric AIDS. DESIGN--Confidential, linked registers based on reporting from obstetricians and paediatricians; anonymous unlinked neonatal HIV serosurveys. SETTING--British Isles. SUBJECTS--Children born to mothers with HIV infection. MAIN OUTCOME MEASURES--Trends in HIV infection and vertical transmission rate. RESULTS--In Scotland and the Irish Republic, where most maternal HIV infection is related to drug misuse, the annual number of reports of children born to infected mothers has fallen since 1989. In England and Wales nearly half of maternal infections have been acquired overseas, and the number of children born to these women, and to women who became infected in Britain, is increasing. In south east England the proportion of live births to women whose infection was identified before delivery was only 17% (50/287), compared with 68% (26/38) in Scotland. The vertical transmission rate was 13.7% (23/168), and 23% of infected children developed AIDS in the first year of life. 41% (38/92) of children born to infected mothers who were ascertained after delivery were breast fed, compared with 5% (12/236) of those ascertained before delivery. CONCLUSIONS--The incidence of vertically transmitted HIV infection is increasing in England and Wales. More extensive antenatal testing would enable infected women to be counselled against breast feeding, which could prevent a substantial proportion of vertical transmission in some areas, and would increase opportunities for early diagnosis and treatment of infected children.     

Meningitis in infancy in England and Wales: follow up at age 5 years

ObjectiveTo describe important sequelae occurring among a cohort of children aged 5 years who had had meningitis during the first year of life and who had been identified by a prospective national study of meningitis in infancy in England and Wales between 1985 and 1987.DesignFollow up questionnaires asking about the children''s health and development were sent to general practitioners and parents of the children and to parents of matched controls. The organism that caused the infection and age at infection were also recorded.SettingEngland and Wales.ParticipantsGeneral practitioners and parents of children who had had meningitis before the age of 1 year and of matched controls.ResultsAltogether, 1584 of 1717 (92.2%) children who had had meningitis and 1391 of 1485 (93.6%) controls were successfully followed up. Among children who survived to age 5 years 247 of 1584 (15.6%) had a disability; there was a 10-fold increase in the risk of severe or moderate disability at 5 years of age among children who had had meningitis (relative risk 10.3, 95% confidence interval 6.7 to 16.0, P<0.001). There was considerable variation in the rates of severe or moderate disability in children infected with different organisms.ConclusionThe long term consequences of having meningitis during the first year of life are significant: 32 of 1717 (1.8%) children died within five years. Not only did almost a fifth of children with meningitis have a permanent, severe or moderately severe disability, but subtle deficits were also more prevalent.

What is already known on this topic

Meningitis in infancy is associated with important long term consequencesThere is considerable variation in outcome depending on which organism caused the infection

What this study adds

This follow up study of 1717 children who had meningitis in infancy found that they had a 10-fold increase in risk of severe or moderate disabilities at age 5 years compared with children in the control groupThe outcome of having meningitis was associated with the age at infection, and children who had meningitis in the neonatal period were more likely to have health and development problems than those older than 1 monthSubtle deficits, such as middle ear disease and visual and behavioural problems, were more prevalent among children who had had meningitis in infancy     

Serum screening for Down's syndrome: experiences of obstetricians in England and Wales.

OBJECTIVES--To assess the experiences of obstetricians in England and Wales of serum screening for Down''s syndrome. DESIGN--Postal questionnaire survey. SUBJECTS--Questionnaires were sent to all practising obstetricians in England and Wales with nonacademic appointments who had not participated in an earlier (randomly sampled) survey of obstetricians'' attitudes (n = 555). Responses were received from 393 (71%), of which 351 were analysed. The data represent about one third of obstetric consultants in England and Wales. MAIN OUTCOME MEASURES--The extent of use of serum screening for Down''s syndrome, and the problems encountered. RESULTS--Serum screening for Down''s syndrome was being offered on some basis by virtually all obstetricians in the survey. Nearly half the sample said that they did not have adequate resources for counselling all the women to whom screening was offered. Many problems were reported, which in all cases were more common than equivalent problems encountered with serum screening for neural tube defects. Over 80% (289) said that women not understanding the test was a problem. CONCLUSIONS--There is considerable confusion associated with serum screening for Down''s syndrome. The precedent of serum screening for neural tube defects does not seem to have lessened the problems experienced, rather the contrary. Many obstetricians report inadequate resources for counselling, which is consistent with the high prevalence of problems associated with women not understanding the test. There is an urgent need to consider what counselling should consist of and who should undertake it and to ensure that necessary resources are available.     

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.     

Final results from 10 year cohort of patients undergoing surveillance for Barrett's oesophagus: observational study

ObjectivesTo review the benefit of an endoscopic surveillance programme for patients with Barrett''s oesophagus.DesignObservational study.SettingUniversity teaching hospital.Participants409 patients in whom Barrett''s oesophagus was identified during 1984-94; 143 were entered into the annual surveillance programme.ResultsThe average period of surveillance was 4.4 years; 55 patients were reassessed in 1994 but only eight remained in the programme in 1999, withdrawal being due to death (not from carcinoma of the oesophagus), illness, or frailty. Five of the patients who entered surveillance developed carcinoma of the oesophagus. Only one cancer was identified as a result of a surveillance endoscopy, the others being detected during endoscopy to investigate altered symptoms. Of the 266 patients who were not suitable for surveillance, one died from oesophageal cancer and 103 from other causes. Surveillance has resulted in 745 endoscopies and about 3000 biopsy specimens.ConclusionThe current surveillance strategy has limited value, and it may be appropriate to restrict surveillance to patients with additional risk factors such as stricture, ulcer, or long segment (>80 mm) Barrett''s oesophagus.     

Be your own coroner: an audit of 500 consecutive deaths in a general practice.

General practitioners'' medical records of a geographically defined population of about 1600-1800 have been retained since 1964. Details of care by general practitioners and hospital correspondence were available for 500 deaths (277 men, 223 women) from 1964 to 1985, including deaths at home, at work, in the street, in short term and long term institutional care, and within six months of release from institutional care. The periods 1964-73 and 1974-85 were compared. The proportion of men aged greater than or equal to 80 who died increased from 20 (14%) in 1964-73 to 22 (16%) in 1974-85, but the proportion of women aged greater than or equal to 80 who died increased from 21 (23%) to 50 (39%). Of all deaths, 223 (45%) were thought to have had avoidable causal factors, of which 132 (59%) were attributed to patients, 45 (20%) to the general practitioner, 9 (4%) to hospitals, and 37 (17%) to others. The number of deaths related to smoking decreased from 31 (43%) in men aged less than 70 to 19 (30%) but in women aged less than 70 increased from 4 (10%) to 11 (26%). The proportion of deaths in women who were already dependent six months before death increased from 55 (58%) to 81 (63%) but in men remained constant at 64 (46%) in the first period and 62 (46%) in the second. Nearly two thirds of all deaths occurred at home in both periods--about twice the proportion for England and Wales--but the proportion of men dying at home decreased from 87 (62%) to 76 (56%). A critical analysis of deaths in whole populations by primary care teams can identify changes that are needed both in the work and organisation of the team and in the behaviour of the population itself.     

Snowmobile-related deaths in Ontario: a 5-year review.

OBJECTIVES: To investigate the demographic characteristics and circumstances surrounding fatal snowmobile accidents in Ontario, to examine the risk factors and to observe any fatality trends over the study period. DESIGN: Case series. PATIENTS: All 131 people who died accidentally while operating a snowmobile in Ontario from 1985-86 to 1989-90. Records were obtained from the chief coroner''s office; registration data were obtained from the Ministry of Transportation. RESULTS: Although the absolute number of deaths increased each year, owing to a rapid increase in the number of registered snowmobiles, the risk of death from snowmobile accidents remained relatively constant. Deaths occurred most frequently in northeastern Ontario. Youths and men predominated among the victims. Fatal accidents occurred more often on lakes (in 66% of the cases in which this information was known) than on roads (in 26%) or trails (in 8%). Weekend fatalities predominated, and deaths occurred most often during times of suboptimal lighting (from 4 pm to 8 am). The driver was killed in 84% of the cases in which the person''s role was known. Alcohol use before death was implicated in 69% of the cases, the level exceeding the Ontario legal limit in 59%. CONCLUSION: Snowmobile-related deaths result from factors that are generally avoidable. Strategies need to be instituted to reduce the rate of these events.     

Epidemiology of suicide pacts in England and Wales, 1988-92.

OBJECTIVE: To describe the epidemiology of suicide pacts in England and Wales DESIGN: Analysis of the death certificates and coroners'' records of all people who died in pacts between 1 January 1988 and 31 December 1992. SUBJECTS: 124 people who committed suicide in 62 pacts. RESULTS: Suicide in a pact accounted for 0.6% of all suicides (124/19721), a rate of 0.6 per million people aged 15 and over. Forty eight pacts were between married couples and five were between family members. The mean age was 56 years. 99 of the 124 subjects were of occupational social classes I-III. Poisoning by car exhaust fumes and drugs accounted for 116 deaths, with both members of each pair using the same method. CONCLUSIONS: Suicide pacts are rare and less common than they were 35 years ago, although the epidemiological profile is similar. People who commit suicide in a pact are more likely than those who commit suicide alone to be female, older, married, and of a high social class.     

Post-Discharge Mortality in Children with Severe Malnutrition and Pneumonia in Bangladesh

Background

Post-discharge mortality among children with severe illness in resource-limited settings is under-recognized and there are limited data. We evaluated post-discharge mortality in a recently reported cohort of children with severe malnutrition and pneumonia, and identified characteristics associated with an increased risk of death.

Methods

Young children (<5 years of age) with severe malnutrition (WHO criteria) and radiographic pneumonia on admission to Dhaka Hospital of icddr,b over a 15-month period were managed according to standard protocols. Those discharged were followed-up and survival status at 12 weeks post-discharge was determined. Verbal autopsy was requested from families of those that died.

Results

Of 405 children hospitalized with severe malnutrition and pneumonia, 369 (median age, 10 months) were discharged alive with a follow-up plan. Of these, 32 (8.7%) died in the community within 3 months of discharge: median 22 (IQR 9–35) days from discharge to death. Most deaths were reportedly associated with acute onset of new respiratory or gastrointestinal symptoms. Those that died following discharge were significantly younger (median 6 [IQR 3,12] months) and more severely malnourished, on admission and on discharge, than those that survived. Bivariate analysis found that severe wasting on admission (OR 3.64, 95% CI 1.66–7.97) and age <12 months (OR 2.54, 95% CI 1.1–8.8) were significantly associated with post-discharge death. Of those that died in the community, none had attended a scheduled follow-up and care-seeking from a traditional healer was more common (p<0.001) compared to those who survived.

Conclusion and Significance

Post-discharge mortality was common in Bangladeshi children following inpatient care for severe malnutrition and pneumonia. The underlying contributing factors require a better understanding to inform the potential of interventions that could improve survival.
