Levelling up health in the early years: A cost-analysis of infant feeding and healthcare

BACKGROUND

Although breastfeeding is recommended as the optimal form of nutrition in the first six months, it is not sustained as the predominant mode of feeding infants in Scotland. This study estimated the impact of infant feeding choices on primary and secondary healthcare service costs in a 13-year birth cohort.

METHOD

Using linked administrative datasets, in a retrospective cohort design of 502,948 singletons born in Scotland between 1997 and 2009, we estimated the cost of GP consultations and hospital admissions by area deprivation and mode of infant feeding up to 6-8 weeks for ten common childhood conditions from birth to 27 months. Additionally, we calculated the potential healthcare savings if all infants in the cohort had been exclusively breastfed at 6-8 weeks. Discounting of 1.5% was applied following current health economic conventions and 2009/10 used as the base year.

RESULTS

Over the study period, the estimated cost of hospital admissions in the cohort was £111 million and £2 million for the 2% subset of the cohort with primary care records. Within each quintile of deprivation, exclusively breastfed infants used fewer healthcare services and incurred lower costs compared to infants fed (any) formula milk. At least £10 million of healthcare costs may have been avoided if formula-fed infants had been exclusively breastfed within the first 6-8 weeks of birth.

CONCLUSIONS

This study using a representative birth cohort demonstrates how breastmilk can promote equitable child health by reducing childhood illness and healthcare utilisation in the early years.

Hospital admissions for stress-related presentations among school-aged adolescents during term time versus holidays in England: weekly time series and retrospective cross-sectional analysis

BACKGROUND

Schools are a potential stressor for adolescents and may contribute to emergency hospital admissions.

AIMS

We describe rates of stress-related presentations (SRPs) among school-aged adolescents (11-17 years) during school terms and holidays, and explore differences by age and gender.

METHOD

Using national administrative hospital data, we defined an SRP as an emergency hospital admission with a primary diagnosis related to pain, psychosomatic symptoms (e.g. fatigue) or mental health problems, or with self-harm indicated in any diagnostic position. We estimated incidence rate ratios for weekly SRPs in term time versus holidays from 2014-2015 to 2017-2018, using negative binomial regression models, stratified by age and gender. We estimated the cumulative incidence of any SRP between 11 and 17 years by analysing prior hospital admission histories of adolescents with an SRP in 2017-2018.

RESULTS

Over the 4-year study period, 305 491 SRPs in 171 013 school-aged adolescents accounted for 31% of emergency admissions for this group. SRPs were predominantly for mental health problems or self-harm (38%), or pain (35%). Weekly admission rates for SRPs were higher in term time than holidays for all ages (age-specific incidence rate ratios were 1.15-1.49 for girls and 1.08-1.60 for boys). Rates were highest for girls aged 14 and 15 years. The estimated cumulative incidence of any SRP between 11 and 17 years was 7.9% for girls and 4.1% for boys.

CONCLUSIONS

Hospital admissions for SRPs are common among adolescents, affecting around two girls and one boy in every classroom. Higher rates in term time than holidays suggest that school factors may contribute.

Timing of paediatric orchidopexy in universal healthcare systems: international administrative data cohort study

BACKGROUND

International guidelines in 2008 recommended orchidopexy for undescended testis at 6-12 months of age to reduce the risk of testicular cancer and infertility. Using administrative data from England, Finland, Ontario (Canada), Scotland and Sweden (with data from Victoria (Australia) and Iceland in supplementary analyses), the aim of this study was to investigate compliance with these guidelines and identify potential socioeconomic inequities in the timing of surgery before 1 and 3 years.

METHODS

All boys born in 2003-2011 with a diagnosis code of undescended testis and procedure codes indicating orchidopexy before their fifth birthday were identified from administrative health records. Trends in the proportion of orchidopexies performed before 1 and 3 years of age were investigated, as were socioeconomic inequities in adherence to the guidelines.

RESULTS

Across all jurisdictions, the proportion of orchidopexies occurring before the first birthday increased over the study period. By 2011, from 7·6 per cent (Sweden) to 27·9 per cent (Scotland) of boys had undergone orchidopexy by their first birthday and 71·5 per cent (Sweden) to 90·4 per cent (Scotland) by 3 years of age. There was limited evidence of socioeconomic inequities for orchidopexy before the introduction of guidelines (2008). Across all jurisdictions for boys born after 2008, there was consistent evidence of inequities in orchidopexy by the first birthday, favouring higher socioeconomic position. Absolute differences in these proportions between the highest and lowest socioeconomic groups ranged from 2·5 to 5·9 per cent across jurisdictions.

CONCLUSION

Consistent lack of adherence to the guidelines across jurisdictions questions whether the guidelines are appropriate.

Informing the 'early years' agenda in Scotland: understanding infant feeding patterns using linked datasets

BACKGROUND

Providing infants with the 'best possible start in life' is a priority for the Scottish Government. This is reflected in policy and health promotion strategies to increase breast feeding, which gives the best source of nutrients for healthy infant growth and development. However, the rate of breast feeding in Scotland remains one of the lowest in Europe. Information is needed to provide a better understanding of infant feeding and its impact on child health. This paper describes the development of a unique population-wide resource created to explore infant feeding and child health in Scotland.

METHODS

Descriptive and multivariate analyses of linked routine/administrative maternal and infant health records for 731,595 infants born in Scotland between 1997 and 2009.

RESULTS

A linked dataset was created containing a wide range of background, parental, maternal, birth and health service characteristics for a representative sample of infants born in Scotland over the study period. There was high coverage and completeness of infant feeding and other demographic, maternal and infant records. The results confirmed the importance of an enabling environment--cultural, family, health service and other maternal and infant health-related factors--in increasing the likelihood to breast feed.

CONCLUSIONS

Using the linked dataset, it was possible to investigate the determinants of breast feeding for a representative sample of Scottish infants born between 1997 and 2009. The linked dataset is an important resource that has potential uses in research, policy design and targeting intervention programmes.

Early death in those previously hospitalised for mental healthcare in Scotland: a nationwide cohort study, 1986-2010

OBJECTIVES

To compare the mortality in those previously hospitalised for mental disorder in Scotland to that experienced by the general population.

DESIGN

Population-based historical cohort study using routinely available psychiatric hospital discharge and death records.

SETTING

All Scotland.

PARTICIPANTS

Individuals with a first hospital admission for mental disorder between 1986 and 2009 who had died by 31 December 2010 (34 243 individuals).

OUTCOMES

The main outcome measure was death from any cause, 1986-2010. Excess mortality was presented as standardised mortality ratios (SMRs) and years of life lost (YLL). Excess mortality was assessed overall and by age, sex, main psychiatric diagnosis, whether the psychiatric diagnosis was 'complicated' (ie, additional mental or physical ill-health diagnoses present), cause of death and time period of first admission.

RESULTS

111 504 people were included in the study, and 34 243 had died by 31 December 2010. The average reduction in life expectancy for the whole cohort was 17 years, with eating disorders (39-year reduction) and 'complicated' personality disorders (27.5-year reduction) being worst affected. 'Natural' causes of death such as cardiovascular disease showed modestly elevated relative risk (SMR1.7), but accounted for 67% of all deaths and 54% of the total burden of YLL. Non-natural deaths such as suicide showed higher relative risk (SMR5.2) and tended to occur at a younger age, but were less common overall (11% of all deaths and 22% of all YLL). Having a 'complicated' diagnosis tended to elevate the risk of early death. No worsening of the overall excess mortality experienced by individuals with previous psychiatric admission over time was observed.

CONCLUSIONS

Early death for those hospitalised with mental disorder is common, and represents a significant inequality even in well-developed healthcare systems. Prevention of suicide and cardiovascular disease deserves particular attention in the mentally disordered.
