Effects of gestational age at birth on health outcomes at 3 and 5 years of age: population based cohort study

Objective To investigate the burden of later disease associated with moderate/late preterm (32-36 weeks) and early term (37-38 weeks) birth. Design Secondary analysis of data from the Millennium Cohort Study (MCS). Setting Longitudinal study of infants born in the United Kingdom between 2000 and 2002. Participants 18 818 infants participated in the MCS. Effects of gestational age at birth on health outcomes at 3 (n=14 273) and 5 years (n=14 056) of age were analysed. Main outcome measures Growth, hospital admissions, longstanding illness/disability, wheezing/asthma, use of prescribed drugs, and parental rating of their children’s health. Results Measures of general health, hospital admissions, and longstanding illness showed a gradient of increasing risk of poorer outcome with decreasing gestation, suggesting a “dose-response” effect of prematurity. The greatest contribution to disease burden at 3 and 5 years was in children born late/moderate preterm or early term. Population attributable fractions for having at least three hospital admissions between 9 months and 5 years were 5.7% (95% confidence interval 2.0% to 10.0%) for birth at 32-36 weeks and 7.2% (1.4% to 13.6%) for birth at 37-38 weeks, compared with 3.8% (1.3% to 6.5%) for children born very preterm (<32 weeks). Similarly, 2.7% (1.1% to 4.3%), 5.4% (2.4% to 8.6%), and 5.4% (0.7% to 10.5%) of limiting longstanding illness at 5 years were attributed to very preterm birth, moderate/late preterm birth, and early term birth. Conclusions These results suggest that health outcomes of moderate/late preterm and early term babies are worse than those of full term babies. Additional research should quantify how much of the effect is due to maternal/fetal complications rather than prematurity itself. Irrespective of the reason for preterm birth, large numbers of these babies present a greater burden on public health services than very preterm babies.

Survival of extremely premature babies in a geographically defined population: prospective cohort study of 1994-9 compared with 2000-5

Objective To assess changes in survival for infants born before 26 completed weeks of gestation. Design Prospective cohort study in a geographically defined population. Setting Former Trent health region of the United Kingdom. Subjects All infants born at 22+0 to 25+6 weeks’ gestation to mothers living in the region. Terminations were excluded but all other births of babies alive at the onset of labour or the delivery process were included. Main outcome measures Outcome for all infants was categorised as stillbirth, death without admission to neonatal intensivecare, death before discharge from neonatal intensivecare, and survival to discharge home in two time periods: 1994-9 and 2000-5 inclusive. Results The proportion of infants dying in delivery rooms was similar in the two periods, but a significant improvement was seen in the number of infants surviving to discharge (P<0.001). Of 497 infants admitted to neonatal intensive care in 2000-5, 236 (47%) survived to discharge compared with 174/490 (36%) in 1994. These changes were attributable to substantial improvements in the survival of infants born at 24 and 25 weeks. During the 12 years of the study none of the 150 infants born at 22 weeks’ gestation survived. Of the infants born at 23 weeks who were admitted to intensive care, there was no significant improvement in survival to discharge in 2000-5 (12/65 (18%) in 2000-5 v 15/81 (19%) in 1994-9). Conclusions Survival of infants born at 24 and 25 weeks of gestation has significantly increased. Although over half the cohort of infants born at 23 weeks wasadmitted to neonatalintensive care, there was no improvement in survival at this gestation. Care for infants born at 22 weeks remained unsuccessful.

Should paediatric intensive care be centralised? Trent versus Victoria

BACKGROUND The mortality rate is lower among children admitted to specialist paediatric intensive care units (ICUs) than among those admitted to mixed adult and paediatric units in non-tertiary hospitals. In the UK, however, few children receive intensive care in specialist paediatric units. We compared the ICU mortality rate in children from the area the Trent Health Authority, UK, with the rate in children from Victoria, Australia, where paediatric intensive care is highly centralised. METHODS We studied all children under 16 years of age from Trent and Victoria who received intensive care between April 1, 1994, and March 31, 1995. Children younger than 1 month were excluded unless they had cardiac disorders. We developed a logistic regression model that used information gathered at the time of admission to ICU to adjust for risk of mortality. FINDINGS The rates of admission of children to intensive care were similar for Trent and Victoria (1.22 and 1.18 per 1000 children per year), but the mean duration of an ICU stay was 3.93 days for Trent children compared with 2.14 days for children from Victoria. 74 (7.3%) of the 1014 children from Trent died, compared with 60 (5.0%) of the 1194 children from Victoria. With adjustment for severity of illness at the time of admission to ICU, the odds ratio for the risk of death for Trent versus Victoria was 2.09 (95% CI 1.37-3.19, p < 0.0005). There were 31.7 (14.0-50.4) excess deaths in Trent children, which is equivalent to 42.8% of the deaths in ICU, and 11.1% of all deaths in children between the ages of 1 month and 16 years in Trent. INTERPRETATION If Trent is representative of the whole country, there are 453 (200-720) excess deaths a year in the UK that are probably due to suboptimal results from paediatric intensive care. If the ratio of paediatric ICUs to children were the same in the UK as in Victoria, there would be only 12 paediatric ICUs in the country. Our findings suggest that substantial reductions in mortality could be achieved if every UK child who needed endotracheal intubation for more than 12-24 h were admitted to one of 12 large specialist paediatric ICUs.

The routinization of hospice : charisma and bureaucratization

In 25 years the number of hospices in Britain has multiplied from under 15 in 1965 to over 430 in 1991. During this period, often working out with the mainstream health system, the hospices actively sought to transform terminal care. More recently a process of diversification and legitimation has meant that hospices have become increasingly subject to mainstream influence. Using Webers concept of charisma we examine the development of the hospice movement during this period of expansion. We suggest there are a number of factors leading to the routinization of hospice care including the ways in which it was sponsored and developed at the local level, and pressures toward bureaucratization and professionalization. We make links with recent developments in the health services. Finally we consider whether it is possible for the hospice movement to sustain its founding ideals.

UK collaborative randomised trial of neonatal extracorporeal membrane oxygenation: follow-up to age 4 years

Extracorporeal membrane oxygenation (ECMO) is a supportive intensive-care technique used for babies with acute respiratory failure. We examined morbidity at age 4 years in surviving children recruited to the UK Collaborative ECMO Trial, and provide long-term data on ECMO support compared with contemporary conventional care. The neonatal ECMO policy resulted in improved survival and a favourable outcome. We therefore advocate the safety and efficacy of this intervention.

United Kingdom collaborative randomized trial of neonatal extracorporeal membrane oxygenation: follow-up to age 7 years.

OBJECTIVE. The UK Collaborative ECMO trial provided an opportunity to describe mortality and morbidity associated with a neonatal ECMO policy compared with conventional management. The improved survival in the ECMO group was not offset by an increase in disability at 4 years, but the children were too young to assess educational and other longer-term impacts. The objective of this study was to assess the longer-term impact of these policies at age 7 years. METHODS. A psychologist assessed 90 of the 100 children available for follow-up without prior knowledge of treatment allocation. The assessments took place at the childrens schools within 3 months of their 7th birthdays. RESULTS. Sixty-eight of 89 (76%) children recorded a cognitive level within the normal range. Learning problems were similar in the 2 groups, and there were notable difficulties with spatial and processing tasks. A higher respiratory morbidity and increased risk of behavioral problems among children treated conventionally persisted. Progressive sensorineural hearing loss was found in both groups. CONCLUSIONS. The underlying disease processes appear to be the major influence on morbidity at 7 years. The beneficial influence of an ECMO policy is still present at 7 years.

Extending specialist palliative care to all

How to extend palliative care services to all patients needing them is an issue currently exercising a range of bodies in contemporary Britain. This paper first considers the evidence regarding the needs of dying patients with long term conditions other than cancer and concludes that there is evidence to support their presumed need for palliative care. It then considers five potential barriers to extending specialist palliative care services to non-cancer patients in Britain. These are the skill base of current specialists in palliative care, difficulties in identifying candidates for specialist palliative care, the views of potential users of these services, resource implications and vested interests in present health service arrangements.

Early term and late preterm birth are associated with poorer school performance at age 5 years: a cohort study

Objective To compare school performance at age 5 years in children born at full term (39–41 weeks gestation) with those born at early term (37–38 weeks gestation), late preterm (34–36 weeks gestation), moderately preterm (32–33 weeks gestation) and very preterm (<32 weeks gestation). Design Population-based cohort (UK Millennium Cohort Study). Participants Seven thousand six hundred and fifty children born in 2000–2001 and attending school in England in 2006. Methods School performance was measured using the foundation stage profile (FSP), a statutory assessment by teachers at the end of the childs first school year. The FSP comprises 13 assessment scales (scored from 1 to 9). Children who achieve an average of 6 points per scale and at least 6 in certain scales are classified as ‘reaching a good level of overall achievement’. Results Fifty-one per cent of full term children had not reached a good level of overall achievement; this proportion increased with prematurity (55% in early term, 59% in late preterm, 63% in moderately preterm and 66% in very preterm children). Compared with full term children, an elevated risk remained after adjustment, even in early term (adjusted RR 1.05, 95% 1.00 to 1.11) and late preterm children (adjusted RR 1.12, 95% CI 1.04 to 1.22). Similar effects were noted for ‘not working securely’ in mathematical development, physical development and creative development. The effects of late preterm and early term birth were small in comparison with other risk factors. Conclusions Late preterm and early term birth are associated with an increased risk of poorer educational achievement at age 5 years.

Palliative care in the community for cancer and end-stage cardiorespiratory disease: the views of patients, lay-carers and health care professionals.

Primary care plays an important role in delivering care to people who are dying. However, providing palliative care to people dying with conditions other than cancer may be more problematic, because it may be more difficult to establish an exact prognosis or to identify their needs. This article draws on qualitative research, which explored the views of health professionals, patients and their carers about care provided at the end of life. Differences between the care of people with cancer and those with end-stage cardiorespiratory disease were found in four main areas: management and progression of disease, communication and information, health care in the community and awareness of dying. The research shows that even in PHCTs (primary health care teams) committed to the delivery of palliative care, people dying with end-stage cardiorespiratory disease are less likely than those with cancer to receive full, and easily understood, information, to be aware that they are dying or to receive district nursing care. There is an increasing call for palliative care to be extended to all, but further work is needed to develop appropriate packages of care for those dying with conditions other than cancer.
