Ukrainian migrants' and war refugees' admissions to hospital: evidence from the Polish Nationwide General Hospital Morbidity Study, 2014-2022

BACKGROUND

Considering the rapid influx of Ukrainian migrants and war refugees into Poland, the knowledge of their health condition is becoming increasingly important for health system policy and planning. The aim of the study was to assess war-related changes in the frequency and structure of hospitalizations among Ukrainian migrants and refugees in Poland.

METHODS

The study is based on the analysis of hospital admission records of Ukrainian patients, which were collected in the Nationwide General Hospital Morbidity Study from 01.01.2014 to 31.12.2022.

RESULTS

In the study period, 13,024 Ukrainians were hospitalized in Poland, 51.7% of whom had been admitted to hospital after February 24, 2022. After the war broke out, the average daily hospital admissions augmented from 2.1 to 21.6 person/day. A noticeable increase in the share of women (from 50% to 62%) and children (from 14% to 51%) was also observed. The average age of patients fell from 33.6 ± 0.2 years to 24.6 ± 0.3 years. The most frequently reported hospital events among the migrants until 23.02.2022 were injuries (S00-T98) - 26.1%, pregnancy, childbirth and the puerperium (O00-O99) - 18.4%, and factors influencing health status and contact with health services (Z00-Z99) - 8.4%. After the war started, the incidence of health problems among migrants and war refugees changed, with pregnancy, childbirth and the puerperium (O00-O99) being the most common - 14.9%, followed by abnormal clinical and lab findings (R00-R99) - 11.9%, and infectious and parasitic diseases (A00-B99) - 11.0%.

CONCLUSIONS

Our findings may support health policy planning and delivering adequate healthcare in refugee-hosting countries.

Health service utilisation for acute respiratory infections in infants graduating from the neonatal intensive care unit: a population-based cohort study

BACKGROUND

Despite advances in neonatal intensive care, babies admitted to Neonatal Intensive Care Units (NICU) suffer from adverse outcomes. We aim to describe the longer-term respiratory infectious morbidity of infants discharged from NICU using state-wide population-based linked data in Western Australia.

STUDY DESIGN

We used probabilistically linked population-based administrative data to analyse respiratory infection morbidity in a cohort of 23,784 infants admitted to the sole tertiary NICU, born 2002-2013 with follow up to 2015. We analysed incidence rates of secondary care episodes (emergency department presentations and hospitalisations) by acute respiratory infection (ARI) diagnosis, age, gestational age and presence of chronic lung disease (CLD). Poisson regression was used to investigate the differences in rates of ARI hospital admission between gestational age groups and those with CLD, after adjusting for age at hospital admission.

RESULTS

From 177,367 child-years at risk (i.e., time that a child could experience an ARI outcome), the overall ARI hospitalisation rate for infants and children aged 0-8 years was 71.4/1000 (95% confidence interval, CI: 70.1, 72.6), with the highest rates in infants aged 0-5 months (242.9/1000). For ARI presentations to emergency departments, equivalent rates were 114/1000 (95% CI: 112.4, 115.5) and 337.6/1000, respectively. Bronchiolitis was the most common diagnosis among both types of secondary care, followed by upper respiratory tract infections. Extremely preterm infants (< 28 weeks gestation at birth) were 6.5 (95% CI: 6.0, 7.0) times more likely and those with CLD were 5.0 (95% CI: 4.7, 5.4) times more likely to be subsequently admitted for ARI than those in NICU who were not preterm or had CLD after adjusting for age at hospital admission.

CONCLUSIONS

There is an ongoing burden of ARI in children who graduate from the NICU, especially those born extremely preterm, that persists into early childhood. Early life interventions to prevent respiratory infections in these children and understanding the lifelong impact of early ARI on later lung health are urgent priorities.

COVID-19 transport restrictions in Ireland: impact on air quality and respiratory hospital admissions

Aim

Exposure to poor air quality is a well-established factor for exacerbation of respiratory system diseases (RSDs); whether air pollutants are a cause of the development of RSD, however, remains unclear. This study aimed to examine the relationship between COVID-19 transport restrictions and hospital admissions because of RSD in Dublin city and county for 2020.

Study design

This was a retrospective population-based cohort.

Methods

Admission data were collected from the Health Service Executive Hospital In-patient Enquiry. Daily count of hospital admissions with Dublin city and county address with primary diagnosis of RSD was performed. The daily air nitrogen dioxide (NO₂) data were obtained from the Environmental Protection Agency (EPA).

Results

During the period of transport restrictions, there was a reduction in the annual mean NO₂ from 25 μg/m³ to 17 μg/m³ (P < 0.001), and decreases in hospital admissions for RSD were observed. Among the 9934 patient episodes included in this study, the mean age at admission was 61.5 years, 57.8% were female (n = 5744), and mean (standard deviation) length of stay was 7.5 (13.52) days.

Conclusion

This study, using routinely gathered data, suggests that decreases in ambient NO₂ as related to COVID-19 transport restrictions were significantly associated with lower asthma and chronic obstructive pulmonary disease admissions.

Impact of COVID-19 Lockdown Restrictions: Ambient NO2 and Asthma Hospital Admissions

Aim The World Health Organization (WHO) declared the COVID-19 pandemic a global health emergency. Many countries of the world, including Ireland, closed their borders and imposed nationwide lockdown. During this period, all major anthropogenic transport activities, which contribute to atmospheric pollution, were restricted. The current study examines the impact of the transport restrictions on ambient nitrogen dioxide (NO2) concentrations and hospital admissions for asthma across Ireland. Methods This is a retrospective population-based cohort study. National ambient air quality monitoring network data were analysed to investigation variations in NO2 concentrations. Asthma hospital admissions data were collected from the HSE Hospital In-patient Enquiry (HIPE) for Cork, Dublin, and Meath. Results During the period of transport restrictions, there were reductions in the annual mean NO2 for Cork, Dublin and Meath (i.e. 12µg/m3 to 11µg/m3 (p = 1); 25µg/m3 to 17µg/m3 (p < 0.001); and 23µg/m3 to 21µg/m3 (p = 1)). Reductions in asthma hospital admissions were also observed. Among the 8,471 patient episodes included in this study, the mean [SD] age at admission was 47.2[22.9] years; 61% were female (n=5,134); mean [SD] length of stay was 4.9[10.9] days. Conclusion The findings of this study provide an opportunity to explore the impact of NO2 emissions for Cork, Dublin and Meath on asthma hospital admissions, in order to improve air quality modelling and policy development of management of asthma.

Hospitalizations among children involved in the child protection system: A long-term birth cohort study from infancy to adulthood using administrative data

BACKGROUND

Despite considerable health consequences of child abuse and neglect, there is limited evidence on hospitalizations in this population.

OBJECTIVES

To describe frequency and reasons for hospitalization by lifetime child protection system (CPS) involvement.

PARTICIPANTS

608,540 children born from January 1, 1986 to June 30, 2017 in South Australia, Australia METHODS: Using linked administrative data on CPS involvement and hospitalizations, we descriptively examined cumulative incidence, cumulative count and reasons for hospitalization from infancy to early adulthood by CPS involvement.

RESULTS

By 16.5 years of age, cumulative incidence of ever-being hospitalized was 58% (95% CI 58-58) for children with no CPS involvement and significantly higher (72% (95% CI 71-73) to 88% (95% CI 86-90), P < 0.001) among those with different levels of CPS involvement. Cumulative mean counts of hospitalizations were highest at every age for those placed in out-of-home-care (reaching 7.7 by 16.5 years), almost four times higher than for children with no CPS involvement (2.0 by 16.5 years). Most frequent reasons for hospitalizations were similar across CPS involvement in the early years. From adolescence through early adulthood, mental health, and 'injury, poisoning or toxic effects of drugs' were frequent reasons for hospitalization among individuals with CPS involvement.

CONCLUSIONS

This study highlights the vulnerability of children who have been maltreated, or are at risk of maltreatment, and the urgency of implementing effective preventive strategies early in life including consideration of adequate responses of child protection services. Frequent hospitalizations for mental health and injury confirms the potentially preventable nature of these hospitalizations.

Suicide attempts in Brazil, 1998-2014: an ecological study

Background

Attempted suicide is the main predictor of suicide constituting a major public health issue worldwide. It is estimated that for every completed suicide, 10 to 20 suicide attempts occur. Important part of the occurrences of suicide attempts in Brazil are registered in the hospital information system for coverage of more than 70 % allows to evaluate the extent of this problem in the country. The scope of this article is to analyse hospitalizations resulting from suicide attempts at public hospitals or services contracted out by the public health system (SUS) in Brazil from 1998 to 2014.

Methods

This is an ecological study of secondary morbidity data obtained from the Hospital Information System. The overall rate of suicide attempts per 100 000 (10⁵) individuals and rates stratified by age group and sex were calculated. To measure trends, simple linear regression coefficients were calculated. The hospital mortality rate was calculated per 100 individuals.

Results

The overall rate of hospitalization decreased from 1998 to 2014. The young and adult age groups had the highest hospitalization rates. Men were admitted more and the elderly had higher hospital mortality rates. The main cause of hospitalization was poisoning, accounting for 70.4 % of hospitalizations. Among the people who used poisoning by non-medical drugs as the method of attempted suicide, 58 178 (69.6 %) were men and 49 585 people who are poisoned by medical drugs (60.1 %) were women.

Conclusions

Although hospitalization rates for attempted suicide have declined in Brazil, it remains a serious public health problem. Because a suicide attempt is the main predictor of suicide, studies to identify those most vulnerable to attempted suicide will help in the development of prevention strategies for mental health.
