Hospital care for viral gastroenteritis in socio-economic and geographical context in Sweden 2006-2013

Intersectional inequalities in paediatric infectious diseases: a national cohort study in Sweden

BACKGROUND

It is well known that socially deprived children are more likely to be hospitalised for infections. Less is known about how different social disadvantages interact. Therefore, we examine intersectional inequalities in overall, upper respiratory, lower respiratory, enteric and genitourinary infections in the first 5 years of life.

METHODS

We conducted a population-based retrospective cohort study of Swedish children born between 1998 and 2015. Inequalities were examined using analysis of individual heterogeneity and discriminatory accuracy as the analytical framework. A variable with 60 intersectional strata was created by combining information on maternal education, household income, sex/gender and maternal migration status. We estimated the incidence rates of infectious disease hospitalisation for each intersectional strata and the associations between intersectional strata and infectious disease hospitalisations using logistic regression models. We furthermore quantified the discriminatory ability of the intersectional strata with respect to infectious disease hospitalisation.

RESULTS

The study included 1785 588 children and 318 080 hospital admissions. The highest overall incidence of hospitalisations for infections was found in boys born to low-educated mothers who lived in families with the lowest household income. The overall incidence of infections was unrelated to household income in children born to highly educated mothers. The ability of the intersectional strata to discriminate between children with and without infections was poor.

CONCLUSION

We found that inequalities in paediatric infectious diseases were shaped by the intersections of different social disadvantages. These inequalities should be addressed by public health policies that reach all children.

Socioeconomic circumstances, health-related behaviours and paediatric infections: a mediation analysis

OBJECTIVE

To examine how the effect of disadvantaged socioeconomic circumstances on the risk of paediatric infections is mediated by pregnancy smoking, excess weight during pregnancy and breast feeding in children under 5 years of age.

DESIGN

A population-level, retrospective cohort study. The Swedish Medical Birth Register was combined with the National Patient Register, the longitudinal integration database for health insurance and labour market studies, the Cause of Death Register and a local register held by the Child Health Care Unit in Uppsala Region.

SETTING

Uppsala Region, Sweden.

PATIENTS

63 216 term and post-term singletons born to women who resided in Uppsala Region, Sweden between 1997 and 2015.

MAIN OUTCOME MEASURES

Number of hospital admissions for infectious diseases. Secondary outcomes were the number of hospitalisations for respiratory and enteric infections, respectively.

RESULTS

The effect of disadvantaged socioeconomic circumstances, that is, low maternal education on the overall risk of paediatric infections was mediated to a considerable (33%-64%) proportion by pregnancy smoking, excess weight during pregnancy and breast feeding.

CONCLUSIONS

Pregnancy smoking, excess weight during pregnancy and breast feeding mediate a considerable proportion of the association between deprived socioeconomic circumstances and paediatric infectious diseases. Therefore, inequalities in paediatric infectious diseases may be reduced by public health policies addressing these health-related behaviours.

Emergency department utilisation by homeless children in Dublin, Ireland: a retrospective review

INTRODUCTION

Despite increasing prevalence, European family homelessness remains under-researched.

METHODS

A retrospective review was performed of homeless children attending a paediatric emergency department in Dublin, Ireland, from 1 January 2017 to 31 December 2020. Comparison was made with a random cohort of 1500 non-homeless paediatric attendances in 2019. Homelessness was defined using the European Typology of Homelessness and Housing Exclusion, including those with addresses of no fixed abode, government homeless accommodation and certain residential settings. The objectives were to compare presentations between homeless and non-homeless children. We were interested in determining differences regarding demographics, healthcare utilisation, clinical presentation and outcomes.

RESULTS

Of 197 437 attendances 3138 (1.59%) were homeless. Compared with the non homeless, homeless children were less likely to be ethnically Irish (37.4% vs 74.6%, p<0.001) or have been born in Ireland (82.3% vs 96.2%, p<0.001). Irish Travellers (3% vs 0.8%), Roma (22.5% vs 2.4%) and black (21.1% vs 4.2%) ethnicities were over-represented (p<0.001) in the homeless cohort.Homeless children were younger (age <12 months: 26% vs 16%; p<0.001), less likely to be fully vaccinated (73.6% vs 81.9%, p<0.001) and have registered general practitioners (89.7% vs 95.8%, p<0.001). They were more likely to represent within 2 weeks (15.9% vs 10.5%, p<0.001), and use ambulance transportation (13.2% vs 6.7%, p<0.001). Homeless children had lower acuity presentations (triage category 4-5: 47.2% vs 40.7%, p<0.001) and fewer admissions (5.9% vs 8.4%, p<0.001) than non-homeless children.

DISCUSSION

Infants, Irish Travellers, Roma and black ethnicities were over-represented in homeless presentations. Homeless children had increased reliance on emergency services for primary healthcare needs.

Global and Swedish review of rotavirus vaccines showed considerable reductions in morbidity and mortality

Rotavirus infections cause severe gastroenteritis in small children, with both high morbidity and mortality. The rotavirus vaccine has been recommended by the World Health Organization since 2009 and was being used by 108 countries by 2019. It joined Sweden's national immunisation programme that year, after 5 years of selective regional use. This review summarises the baseline facts and evidence, the most common vaccines and the global direct and indirect effects, with a special focus on Sweden. CONCLUSION: The vaccine has had a considerable impact on global and Swedish morbidity and mortality, but some indirect effects and socioeconomic differentials need research.

All-cause gastroenteritis hospitalisations of children decreased after the introduction of rotavirus vaccine in Stockholm

BACKGROUND

In Stockholm, Sweden, rotavirus vaccination was offered to children born after 1 March 2014. Our aim was to describe rates of hospitalisation due to community-acquired gastroenteritis before and after the introduction of the vaccine, and aetiology, underlying medical conditions and complications in admitted children.

METHODS

We retrospectively included patients from our catchment area hospitalised with a diagnosis of gastroenteritis during ten infection seasons 2008/2009-2017/2018, whereof six seasons prevaccination and four seasons postvaccination. We studied virus detection data and the patients' medical records.

RESULTS

We included 3718 episodes in 3513 children. In 2967 (80%), stools were tested with virus isolation, ELISA, PCR, or bacterial culture; 479 (16%) tested negative. The incidence rates, with 95% confidence intervals, for children <5 years hospitalised for rotavirus gastroenteritis were 2.9 (2.8-3.1) per 1000 person-years prevaccination and 0.65 (0.56-0.74) postvaccination, for a rate ratio (RR) of 0.22 (0.19-0.26, p < .001). The rates for all-cause gastroenteritis were 5.6 (5.4-5.9) prevaccination and 2.5 (2.3-2.7) postvaccination, RR 0.45 (0.42-0.50, p < .001). In 5-17-year-old children norovirus dominated with little change over time. Of patients <5 years, those with underlying conditions constituted a larger proportion postvaccination than prevaccination (30.7% vs. 24.2%, p < .001). A complication other than dehydration, most commonly seizures, arose in 8.8% of the patients <5 years prevaccination and 11.4% postvaccination (p < .05).

CONCLUSIONS

Rotavirus vaccination reduced the number of children <5 years requiring hospital care for gastroenteritis. We saw no replacement of rotavirus by other viruses.

Children hospitalised with four common viral diseases showed epidemiological differences but few socio-economic variations

AIM

This study explored the differences in demographic and socio-economic factors between children hospitalised due to four common viral infections.

METHODS

Demographic data were obtained from Statistics Sweden on >3000 children admitted to Astrid Lindgren Children's Hospital in 2009-2014 with rotavirus, influenza, respiratory syncytial virus (RSV) or chickenpox. We compared demographic and socio-economic factors between case groups using logistic regression with rotavirus cases as reference.

RESULTS

There were differences in the median age at admission; RSV cases were younger (0.4 years), influenza (2.4 years) and chickenpox cases (2.7 years) older than rotavirus cases (1.2 years). RSV, influenza and chickenpox cases lived in families with more children than rotavirus cases. RSV and influenza cases were more likely to have underlying chronic conditions. Mothers of RSV cases were more likely to be born in Sweden. Further socio-economic differences were not robustly confirmed in sensitivity analyses.

CONCLUSION

We found a few differences in demographic factors between children hospitalised with the four common infections, which were mainly explained by the epidemiology and transmission patterns of these infections.

The Effect of Rotavirus Vaccine on Socioeconomic Differentials of Paediatric Care Due to Gastroenteritis in Swedish Infants

Background: Previous Swedish studies have shown a social gradient on paediatric care for viral gastroenteritis. Aim: To study the effect of a free rotavirus vaccine programme on hospital care for viral gastroenteritis. Method: A register-based national cohort study of paediatric in- and outpatient care for viral gastroenteritis in children <2 years old in two Swedish counties in 2014–2017, with the rest of the country as comparison. Adjusted hazard ratios were estimated by the differences-in-differences (DiD) estimator in Cox regression in the entire cohort and by social indicators. Results: Reductions of 37% and 24% for inpatient care, and 11 % and 21% for outpatient care for viral gastroenteritis were found in the Stockholm and Jönköping counties, respectively, after adjusting for time trends and social indicators. For inpatient care, the change was similar over social groups in both counties. In the larger county of Stockholm, smaller reductions in outpatient care were detected for children in socially disadvantaged families. Conclusions: A free rotavirus vaccination programme moderately reduced paediatric care for viral gastroenteritis. There were indications of an increase in socioeconomic differences in paediatric outpatient care for viral gastroenteritis, but further studies are needed to confirm this result in a broader health care perspective.
